Summary of Significant Accounting Policies	Dec. 31, 2021
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Use of Estimates and Assumptions The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained. Among the more significant estimates are those that relate to: 1) ACL for loans and for unfunded credit commitments, 2) valuation of non-marketable and other equity securities, 3) valuation of equity warrant assets, 4) goodwill, intangible assets and other purchase accounting related adjustments and 5) income taxes. Principles of Consolidation and Presentation Our consolidated financial statements include the accounts of SVB Financial Group and consolidated entities. We consolidate entities in which we have a controlling financial interest. Before we determine whether we have a controlling financial interest, we must evaluate whether the entity is a voting interest entity or a variable interest entity ("VIE"). VIEs are entities where investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support and, as a group, lack one of the following characteristics: (a) the power to direct the activities that most significantly impact the entity’s economic performance, (b) the obligation to absorb the expected losses of the entity or (c) the right to receive the expected returns of the entity. We are considered to hold a controlling financial interest in a VIE when we are the primary beneficiary. A primary beneficiary is the party that has both: (a) the power to direct the activities that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses or receive benefits of a VIE that could potentially be significant to a VIE. Generally, the parties that make management and investment decisions, or parties that can unilaterally remove such decision-makers are deemed to have the power to direct the activities of a VIE. When assessing whether we have the obligation to absorb losses or the right to receive benefits from the VIE, we consider all of our economic interests in the VIE, including any fees and other compensation received for providing investment and management services if that compensation is not customary and commensurate with the services provided. Voting interest entities are entities that (a) have sufficient equity to finance their activities and (b) provide the equity investors power to make significant decisions relating to the entity’s operations. For such entities, we have a controlling financial interest if we hold a majority of voting rights. All significant intercompany accounts and transactions with consolidated entities have been eliminated. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, cash balances due from banks, interest-earning deposits, Federal Reserve deposits, federal funds sold, securities purchased under agreements to resell and other short-term investment securities. For the consolidated statements of cash flows, we consider cash equivalents to be investments that are readily convertible to known amounts of cash, so near to their maturity that they present an insignificant risk of change in fair value due to changes in market interest rates, and purchased in conjunction with our cash management activities. Investment Securities Available-for-Sale Securities and the Allowance for Credit Losses on Available-for-Sale Securities Our AFS securities portfolio is a fixed income investment portfolio that is managed to earn an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and credit diversification and meeting our asset and liability management objectives. The accretion of discounts and amortization of premiums over the contractual terms of the underlying securities are included in interest income. We use estimates of future principal prepayments when applying the effective interest method to prepayable securities. Unrealized gains and losses on AFS securities, net of applicable taxes, are reported in AOCI, a separate component of SVBFG's stockholders' equity. Impairment losses on AFS securities are recognized through earnings when we intend to sell an AFS security, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost. Additionally, we evaluate whether a credit loss exists for securities that we intend to hold. We consider all factors in determining whether a credit loss exists, including the period over which the debt security is expected to recover. A credit impairment is recognized through a valuation allowance against the security with an offset through earnings. The allowance is limited to the amount that fair value is less than the amortized cost basis. Held-to-Maturity Securities and the Allowance for Credit Losses on Held-to-Maturity Securities Debt securities purchased with the positive intent and ability to hold to its maturity are classified as HTM securities and are recorded at amortized cost, net of any ACL. Effective January 1, 2020, we measure ECL on HTM securities on a collective basis by major security type and standard credit rating. Certain securities in our HTM securities portfolio are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. With respect to these securities, we consider the risk of credit loss to be zero and, therefore, we do not record an ECL. The estimate of ECL on our HTM securities that are not guaranteed by the U.S. government considers historical credit loss information and severity of loss in the event of default and leverages external data adjusted for current conditions. A reasonable and supportable forecast period of one year is applied, with immediate reversion to long-term average historical loss rates when remaining contractual lives of securities exceed one year. We do not estimate ECL on AIR from HTM securities as AIR is reversed or written off when the full collection of the AIR related to a security becomes doubtful. AIR from HTM securities totaled $225 million at December 31, 2021 and $55 million at December 31, 2020 and is excluded from the amortized cost disclosures within our HTM security disclosures in Note 9—“Investment Securities” as it is included and reported separately within "Accrued interest receivable and other assets" in our consolidated balance sheets. ECL on bonds that do not share common risk characteristics with our collective portfolio are individually measured based on net realizable value, or the difference between the discounted value of the expected future cash flows and the recorded amortized cost basis of the security. Transfers of investment securities into the HTM category from the AFS category are made at fair value at the date of transfer. The net unrealized gains, net of tax, are retained in other comprehensive income, and the carrying value of the HTM securities are amortized over the life of the securities in a manner consistent with the amortization of a premium or discount. Non-Marketable and Other Equity Securities Non-marketable and other equity securities include investments in venture capital and private equity funds, SPD-SVB, debt funds, private and public portfolio companies, including public equity securities held as a result of equity warrant assets exercised, and investments in qualified affordable housing projects. A majority of these investments are managed through our SVB Capital funds business in funds of funds and direct venture funds. Our accounting for investments in non-marketable and other equity securities depends on several factors, including the level of ownership, power to control and the legal structure of the subsidiary making the investment. As further described below, we base our accounting for such securities on: (i) fair value accounting, (ii) measurement alternative for other investments without a readily determinable fair value, (iii) equity method accounting and (iv) the proportional amortization method which is used only for qualified affordable housing projects. Fair Value Accounting Our consolidated managed funds qualify as investment companies and therefore report their investments at estimated fair value, with unrealized gains and losses reflected as gains on investment securities, net, a component of noninterest income. The portion of any investment gains or losses attributable to other limited partners is reflected as net income attributable to noncontrolling interests and adjusts our net income to reflect its percentage ownership. Our consolidated managed funds of funds make investments in venture capital and private equity funds. A summary of our ownership interests in such funds as of December 31, 2021 is presented in the following table: Limited partnership Company Direct and Indirect Ownership in Limited Partnership Managed funds of funds Strategic Investors Fund, LP 12.6 % Capital Preferred Return Fund, LP 20.0 Growth Partners, LP 33.0 Our direct investments in public portfolio companies are valued based on quoted market prices less a discount if the securities are subject to certain security specific sale restrictions. Gains or losses resulting from changes in the net asset value are recorded as gains on investment securities, net, a component of noninterest income. Other Investments without a Readily Determinable Fair Value Our direct investments in private companies do not have a readily determinable fair value. We measure these investments at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments from the same issuer. Such changes are recognized through earnings. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted. Our investments in unconsolidated funds where we do not have the ability to exercise significant influence over their operating and financial policies are valued using the net asset value as obtained from the general partners of the fund investments because the funds do not have a readily determinable fair value. The general partners of these funds prepare their financial statements using guidance consistent with fair value accounting. We account for differences between our measurement date and the date of the fund investment's net asset value by using the most recent available financial information from the investee general partner, for example September 30th, for our December 31st consolidated financial statements. We adjust the value of our investments for any contributions paid, distributions received from the investment and known significant fund transactions or market events about which we are aware through information provided by the fund managers or from publicly available transaction data during the reporting period. Gains or losses resulting from changes in the net asset value are recorded as gains on investment securities, net, a component of noninterest income. Equity Method Our equity method non-marketable securities consist of investments in venture capital and private equity funds, privately-held companies, debt funds, and joint ventures. Our equity method non-marketable securities and related accounting policies are described as follows: • Equity securities and investments in limited partnerships, such as preferred or common stock in privately-held companies in which we have the ability to exercise significant influence over the investees' operating and financial policies through voting interests, board involvement or other influence are accounted for under the equity method, and • The Bank's joint venture bank in China (SPD-SVB), for which we have 50 percent ownership, is accounted for under the equity method. We recognize our proportionate share of the results of operations of these equity method investees in our results of operations, based on the most current financial information available from the investee. We review our investments accounted for under the equity method at least quarterly for possible other-than-temporary impairment. Our review typically includes an analysis of facts and circumstances for each investment, the expectations of the investment's future cash flows and capital needs, variability of its business and the company's exit strategy. For our fund investments, we use the net asset value per share as provided by the general partners of the fund investments. We account for differences between our measurement date and the date of the fund investment's net asset value by using the most recent available financial information from the investee general partner, for example September 30 th , for our December 31 st consolidated financial statements. We adjust the value of our investments for any contributions paid, distributions received from the investment, and known significant fund transactions or market events about which we are aware through information provided by the fund managers or from publicly available transaction data during the reporting period. We reduce our investment value when we consider declines in value to be other-than-temporary and recognize the estimated loss as a loss on investment securities, a component of noninterest income. Proportional Amortization Method In order to fulfill our responsibilities under the CRA, we invest as a limited partner in low income housing partnerships that operate qualified affordable housing projects and generate tax benefits, including federal low income housing tax credits, for investors. The partnerships are deemed to be VIEs because they do not have sufficient equity investment at risk and are structured with non-substantive voting rights. We are not the primary beneficiary of the VIEs and do not consolidate them. Our investments in low income housing partnerships are recorded in non-marketable and other equity securities within our investment securities portfolio on the consolidated balance sheet. As a practical expedient, we amortize the investment in proportion to the allocated tax benefits under the proportional amortization method of accounting and present such benefits net of investment amortization in income tax expense. Loans Loans are reported at amortized cost which consists of the principal amount outstanding, net of unearned loan fees. Unearned loan fees reflect unamortized deferred loan origination and commitment fees net of unamortized deferred loan origination costs. In addition to cash loan fees, we often obtain equity warrant assets that give us an option to purchase a position in a client company's stock in consideration for providing credit facilities. The grant date fair values of these equity warrant assets are deemed to be loan fees and are deferred as unearned income and recognized as an adjustment of loan yield through loan interest income. The net amount of unearned loan fees is amortized into loan interest income over the contractual terms of the underlying loans and commitments using the constant effective yield method, adjusted for actual loan prepayment experience, or the straight-line method, as applicable. Allowance for Credit Losses The allowance for credit losses for loans considers credit risk and is adjusted by a provision for ECL charged to expense and reduced by the charge-off of loan amounts, net of recoveries. Our allowance for credit losses is an estimate of expected losses inherent with the Company's existing loans at the balance sheet date. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. Loan Portfolio Segments and Classes of Financing Receivables The process to estimate the ECL on loans involves procedures to appropriately consider the unique characteristics of our loan portfolio. Our eight portfolio segments are determined by using the following risk dimensions: (i) underwriting methodology, (ii) industry niche and (iii) life stage. The eight portfolio segments are further disaggregated into eleven classes of financing receivable, or risk-based segments, and represents the level at which credit risk is monitored. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process to estimate ECL. For further information refer to Note 9—“Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments.” Upon completing the acquisition of Boston Private, we evaluated the impact of the acquired loan portfolio on our existing portfolio segments and classes of financing receivables. We have modified both levels of disaggregation to accommodate Boston Private loans. The following provides additional information regarding our portfolio segments and classes of financing receivables: • Global Fund Banking (segment and class) – The vast majority of our GFB portfolio segment consists of capital call lines of credit, the repayment of which is dependent on the payment of capital calls by the underlying limited partner investors in funds managed by certain private equity and venture capital firms. • Investor Dependent (segment) – Loans are made primarily to technology and life science/healthcare companies. These borrowers typically have modest or negative cash flows and rarely have an established record of profitable operations. Repayment of these loans may be dependent upon receipt by borrowers of additional equity financing from venture capital firms or other investors, or in some cases, a successful sale to a third party or an IPO. This portfolio segment is further disaggregated into two classes of financing receivables: ◦ Early-Stage (class) – Loans to pre-revenue, development-stage companies and companies that are in the early phases of commercialization, with revenues of up to $5 million. ◦ Growth Stage (class) – Loans to growth-stage enterprises. We consider companies with revenues between $5 million and $15 million, or pre-revenue clinical-stage biotechnology companies, to be Mid-Stage, and companies with revenues in excess of $15 million to be Later Stage. • Cash Flow Dependent and Innovation C&I (segment) – Loans are made primarily to technology and life science/healthcare companies that are not Investor Dependent, i.e. repayment is not dependent on additional equity financing, a successful sale or an IPO. This portfolio segment consists of two classes of financing receivables: ◦ Cash Flow Dependent – SLBO (class) – Loans are typically used to assist a select group of private equity sponsors with the acquisition of businesses, are larger in size, and repayment is generally dependent upon the cash flows of the combined entities. Acquired companies are typically established, later-stage businesses of scale and characterized by reasonable levels of leverage with loan structures that include meaningful financial covenants. The sponsor’s equity contribution is often 50 percent or more of the acquisition price. ◦ Innovation C&I (class) – Other C&I loans in innovation sectors such as technology and life science/healthcare industries. These loans are dependent on either the borrower’s cash flows or balance sheet for repayment. Cash flow dependent loans require the borrower to maintain cash flow from operations that is sufficient to service all debt. Borrowers must demonstrate normalized cash flow in excess of all fixed charges associated with operating the business. Balance sheet dependent loans include asset-based loans and are structured to require constant current asset coverage (i.e. cash, cash equivalents, accounts receivable, and, to a much lesser extent, inventory) in an amount that exceeds the outstanding debt. The repayment of these arrangements is dependent on the financial condition, and payment ability, of third parties with whom our clients do business. • Private Bank (segment and class) – Loans to our Private Bank clients who are primarily private equity/venture capital professionals and executives in the innovation companies as well as high net worth clients acquired from Boston Private. We offer a customized suite of private banking services, including mortgages, home equity lines of credit, restricted and private stock loans, personal capital call lines of credit, lines of credit against liquid assets and other secured and unsecured lending products. In addition, we provide owner occupied commercial mortgages to Private Bank clients and real estate secured loans to eligible employees through our EHOP. • CRE (segment and class) – Generally acquisition financing loans for commercial properties such as office buildings, retail properties, apartment buildings, and industrial/warehouse space. • Other C&I (segment and class) – Loans that include working capital and revolving lines of credit, as well as term loans for equipment and fixed assets. These loans are primarily to clients that are not in the technology and life sciences/healthcare industries. Additionally, this portfolio segment contains commercial tax-exempt loans to not-for-profit private schools, colleges, public charter schools and other not-for-profit organizations. • Premium Wine and Other (segment) – This portfolio segment consists of two classes of financing receivables: ◦ Premium Wine (class) – Loans to wine producers, vineyards and wine industry or hospitality businesses across the Western United States. A large portion of these loans are secured by real estate collateral such as vineyards and wineries. ◦ Other (class) – Primarily construction and land loans for financing new developments as well as financing for improvements to existing buildings. These also include our community development loans made as part of our responsibilities under the CRA. • PPP (segment and class) – Combined loans issued through the PPP. These loans represent clients across all portfolio segments and are guaranteed by the SBA. We maintain a systematic process for the evaluation of individual loans and portfolio segments for inherent risk of estimated credit losses for loans. At the time of approval, each loan in our portfolio is assigned a credit risk rating. Credit risk ratings are assigned on a scale of 1 to 10, with 1 representing loans with a low risk of nonpayment, 9 representing loans with the highest risk of nonpayment and 10 representing loans which have been charged-off. The credit risk ratings for each loan are monitored and updated on an ongoing basis. This credit risk rating process includes, but is not limited to, consideration of such factors as payment status, the financial condition and operating performance of the borrower, borrower compliance with loan covenants, underlying collateral values and performance trends, the degree of access to additional capital, the presence of credit enhancements such as third party guarantees (where applicable), the degree to which the borrower is sensitive to external factors and the depth and experience of the borrower's management team. Our policies require a committee of senior management to review, at least quarterly, credit relationships with a credit risk rating of 5 through 9 that exceed specific dollar values. Expected Credit Loss Measurement The methodology for estimating the amount of ECL reported in the ACL is the sum of two main components: (1) ECL assessed on a collective basis for pools of loans that share similar risk characteristics which includes a qualitative adjustment based on management’s assessment of the risks that may lead to a future loan loss experience different from our historical loan loss experience and (2) ECL assessed for individual loans that do not share similar risk characteristics with other loans. We do not estimate ECL on AIR on loans as AIR is reversed or written off when the full collection of the AIR related to a loan becomes doubtful, which is when loans are placed on nonaccrual status. AIR on loans totaled $171 million at December 31, 2021 and $126 million at December 31, 2020 and is excluded from the amortized cost disclosures in Note 10—“Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments”, as it is included and reported separately within "Accrued interest receivable and other assets" in our consolidated balance sheets. While the evaluation process of our ACL on loans uses historical and other objective information, the classification of loans and the estimate of the ACL for loans rely on the judgment and experience of our management. A committee comprised of senior management evaluates the appropriateness of the ACL for loans, which includes review of loan portfolio segmentation, quantitative models, internal and external data inputs, economic forecasts, credit risk ratings and qualitative adjustments. Loans That Share Similar Risk Characteristics with Other Loans We derive an estimated ECL assumption from a non-discounted cash flow approach based on our portfolio segments discussed above. This approach incorporates a calculation of three predictive metrics: (1) PD, (2) LGD and (3) EAD, over the estimated life of the exposure. PD and LGD assumptions are developed based on quantitative models and inherent risk of credit loss, both of which involve significant judgment. Renewals and extensions within our control are not considered in the estimated contractual term of a loan. However, we include potential extensions if management has a reasonable expectation that we will execute a TDR with the borrower. The quantitative models are based on historical credit loss experience, adjusted for probability-weighted economic scenarios. These scenarios are used to support a reasonable and supportable forecast period of three years for all portfolio segments. To the extent the remaining contractual lives of loans in the portfolio extend beyond this three-year period, we revert to historical averages using an autoregressive method of mean reversion that will continue to gradually trend towards the mean historical loss over the remaining contractual lives of loans, adjusted for prepayments. The macroeconomic scenarios are reviewed on a quarterly basis. We also apply a qualitative factor adjustment to the results obtained through our quantitative ECL models to consider model imprecision, emerging risk assessments, trends and other subjective factors that may not be adequately represented in quantitative ECL models. These adjustments to historical loss information are for asset specific risk characteristics, and also reflect our assessment of the extent that current conditions and reasonable and supportable forecasts differ from conditions that existed during the period over which historical information was evaluated. These adjustments are aggregated to become our qualitative allocation. Based on our qualitative assessment estimate of changing risks in the lending environment, the qualitative allocation may vary significantly from period to period and may include, but is not limited to, consideration of the following factors: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; • Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the experience, ability and depth of lending management and other relevant staff; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans; • Changes in the quality of our loan review system; • Changes in the value of underlying collateral for collateral-dependent loans; • The existence and effect of any concentrations of credit, and changes in the level of such concentrations; • The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio; and • The effect of limitations of available data, model imprecision and recent macro-economic factors that may not be reflected in the forecast information. Loans That Do Not Share Similar Risk Characteristics We monitor our loan pools to ensure all assets therein continue to share similar risk characteristics with other financial assets inside the pool. Changes in credit risk, borrower circumstances or the recognition of write-offs may indicate that a loan's risk profile has changed, and the asset should be removed from its current pool. For a loan that does not share risk characteristics with other loans, ECL is measured based on the net realizable value, that is, the difference between the discounted value of the expected future cash flows and the amortized cost basis of the loan. When a loan is collateral-dependent and the repayment is expected to be provided substantially through the operation or sale of the collateral, the ECL is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral will be determined by the most recent appraisal, as adjusted to reflect a reasonable marketing period for the sale of the asset(s) and an estimate of reasonable selling expenses. Collateral-dependent loans will have independent appraisals completed and accepted at least annually. Allowance for Credit Losses: Unfunded Credit Commitments We maintain a separate ACL for unfunded credit commitments which is included in other liabilities and the related ECL in our provision for credit losses. We estimate the amount of expected losses by using historical trends to calculate a probability of an unfunded credit commitment being funded and derive historical lifetime expected loss factors for each portfolio segment similar to our funded loan ECL. The collectively assessed ECL for unfunded credit commitments also includes the same qualitative allocations applied for our funded loan ECL. For unfunded credit commitments related to loans that do not share similar risk characteristics with other loans, where applicable, a separate estimate of ECL will be included in our total ACL on unfunded credit commitments. Loan commitments that are determined to be unconditionally cancellable by the Company do not require an ACL on unfunded credit commitments. Uncollectible Loans and Write-offs Our charge-off policy applies to all loans, regardless of portfolio segment. Commercial loans are considered for a full or partial charge-off in the event that principal or interest is over 180 days past due and the loan lacks sufficient collateral and it is not in the process of collection. Consumer loans are considered for a full or partial charge-off in the event that principal or interest is over 120 days past due and the loan lacks sufficient collateral and it is not in the process of collection. We also consider writing off loans in the event of any of the following circumstances: 1) the loan, or a portion of the loan is deemed uncollectible due to: a) the borrower's inability to make recurring payments, b) material changes in the borrower's financial condition, or c) the expected sale of all or a portion of the borrower's business is insufficient to repay the loan in full, or 2) the loan has been identified for charge-off by regulatory authorities. Troubled Debt Restructurings A TDR arises from the modification of a loan where we have granted a concession to the borrower related to the borrower's financial difficulties that we would not have otherwise considered for economic or legal reasons. These concessions may include: (1) deferral of payment for more than an insignificant period of time that does not include sufficient offsetting bor

Business Combination and Asset Acquisition [Abstract]
Business Combination	Business Combination Boston Private On July 1, 2021, we acquired, by merger, 100 percent of the voting equity interests of Boston Private Financial Holdings, Inc., the parent company of Boston Private Bank & Trust Company. The acquisition of Boston Private accelerates SVB’s private bank and wealth management offering, strengthening SVB’s overall platform and ability to fully meet the financial needs of its clients. The acquisition was accounted for as a business combination and accordingly, the results of Boston Private's operations have been included in the Company's consolidated financial statements from the date of acquisition. We acquired Boston Private for $1.2 billion comprised of $2.10 in cash and 0.0228 shares of SVB common stock for each Boston Private share. For the transaction, we issued approximately 1.9 million shares of SVB common stock and registered an additional 99,000 shares of SVB common stock issuable upon the exercise, vesting or settlement of converted legacy Boston Private equity awards. The following table summarizes the allocation of the purchase price to the net assets of Boston Private as of July 1, 2021: (Dollars in millions) July 1, 2021 Cash paid $ 174 Share-based consideration 1,050 Replacement equity awards 10 Total purchase consideration $ 1,234 Fair value of net assets acquired 1,033 Goodwill $ 201 The following table summarizes the estimated fair value of assets acquired and liabilities assumed upon the finalization of the purchase: (Dollars in million) July 1, 2021 Assets acquired: Cash and cash equivalents $ 1,290 Investment securities 1,429 Loans 7,217 Premises and equipment 39 Intangible assets 104 Right-of-use assets 107 Other assets 284 Total assets acquired 10,470 Liabilities assumed: Deposits 8,983 Borrowings 132 Lease liabilities 103 Other liabilities 219 Total liabilities assumed 9,437 Fair value of net assets acquired $ 1,033 The Company recognized identifiable intangible assets of $104 million and goodwill of $201 million as a result of the acquisition. Intangible assets of $104 million are subject to amortization over their estimated useful lives. The goodwill recorded includes expected revenue-generating synergies driven by the broadening of our product suite and strength of the combined platform, providing our teams with expanded capabilities, technology and scalability to meet the increasing needs of our Private Bank clients. Goodwill amounts have been allocated to the SVB Private Bank reporting segment and will not be deductible for tax purposes. The following table summarizes the fair value and estimated useful lives of the other intangible assets at the date of acquisition: (Dollars in millions) Estimated Fair Value Weighted Average Estimated Useful Life - in Years Other intangible assets: Customer relationships $ 85 20 Other 19 6 Total other intangible assets $ 104 Of the $7.2 billion net loans acquired, $1.4 billion exhibited credit deterioration on the date of purchase. The following table provides a summary of these PCD loans at acquisition: (Dollars in millions) July 1, 2021 Par value of PCD loans $ 1,368 PCD ACL at acquisition (22) Non-credit premium on PCD loans 43 Purchase price of PCD loans $ 1,389 Due to the various conversions of Boston Private systems since the date of acquisition, as well as other streamlining and continuing integration of Boston Private's operating activities into those of the Company, reporting for revenue and net income of the former Boston Private operations for the period subsequent to the acquisition is impracticable. Supplementary pro forma financial information related to the acquisition is not included because the impact to the Company's consolidated statements of income is not material. Direct expenses related to the acquisition of Boston Private were expensed as incurred and were $22 million for twelve months ended December 31, 2021. All expenses were included in merger-related charges, a component of noninterest expense, with the exception of $6 million attributable to the three months ended March 31, 2021, which were recorded in professional services. MoffettNathanson LLC On December 10, 2021, we acquired 100 percent of the voting equity interests of MoffettNathanson LLC, a New York-based independent sell-side research firm known for its coverage of high-growth, disruptive companies in the Media, Communications and Technology sectors. The acquisition enables SVB’s investment banking business, SVB Securities, to expand its research coverage to include companies in both the healthcare and technology industries. The acquisition was accounted for as a business combination and accordingly, the results of MoffettNathanson LLC operations have been included in the Company's consolidated financial statements from the date of acquisition.

Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Share-based compensation expense was recorded net of estimated forfeitures for 2021, 2020 and 2019, such that expense was recorded only for those share-based awards that are expected to vest. In 2021, 2020 and 2019, we recorded share-based compensation and related benefits as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Share-based compensation expense $ 136 $ 84 $ 67 Income tax benefit related to share-based compensation expense (35) (20) (16) Capitalized compensation costs 1 1 2 Equity Incentive Plans Our 2006 Equity Incentive Plan (the “2006 Incentive Plan”) was adopted in May 2006, and is amended from time to time. The 2006 Incentive Plan provides for the grant of various types of incentive awards, of which the following have been granted: (i) stock options; (ii) restricted stock awards; (iii) restricted stock units (subject to either time-and/or performance-based vesting); and (iv) other cash or stock settled equity awards. Eligible participants in the 2006 Incentive Plan include directors, employees and consultants. Subject to the provisions of Section 16 of the 2006 Incentive Plan, the maximum aggregate number of shares that may be awarded and sold thereunder is 12,028,505. Restricted stock awards/units are counted against the available-for-issuance limits of the 2006 Incentive Plan as two shares for every one share awarded. Further, if shares acquired under any such award are forfeited, repurchased by SVB Financial, used to satisfy the tax withholding obligations related to an award or otherwise canceled and would otherwise return to the 2006 Incentive Plan, two times the number of such shares will return to the 2006 Incentive Plan and will again become available for issuance. Under the terms of the 2006 Incentive Plan, and subject to certain exceptions, awards granted under the plan are subject to a minimum of at least one year of vesting. Generally in practice, restricted stock units vest annually over four years and require continued employment or other service through the vesting period. Performance-based restricted stock awards/units granted to executives generally vest upon meeting certain performance-based objectives over a three year period and, typically, additional time-based vesting follow the end of the performance period, and require continued employment or other service through the vesting date. Stock options typically vest annually over four years, from the grant date based on continued employment or other service, and expire no later than seven years after the grant date. A select number of awards granted to certain employees will continue to vest in accordance with the normal vesting schedule in the event that the employee retires (upon meeting certain age and service criteria) at least six months after the grant date and prior to the end of the vesting period, subject to certain conditions. For accounting purposes, the requisite service period for these awards is reduced on an individual basis, as necessary, to reflect the employee’s individual retirement eligibility date. The underlying BPFH shares of the legacy Boston Private stock options and restricted stock units were converted into shares of the Company in connection with the Boston Private acquisition on July 1, 2021. Information in this footnote includes the converted legacy Boston Private awards unless otherwise indicated. Upon acquisition, 28,724 options and 67,542 restricted stock units were assumed by the Company from legacy Boston Private plans. All awards assumed from the legacy Boston Private plans will be settled under the respective legacy plans. No future awards will be made under these plans. We maintain the 1999 ESPP under which participating employees may annually contribute up to 10 percent of their gross compensation (not to exceed $25,000) to purchase shares of our common stock at 85 percent of its fair market value at either the beginning or end of each six-month offering period, whichever price is less. To be eligible to participate in the ESPP, an employee must, among other requirements, be employed by the Company on both the date of offering and date of purchase, and be employed customarily for at least 20 hours per week and at least five months per calendar year. We issued 110,886 shares and received $41 million in cash under the ESPP in 2021. At December 31, 2021, a total of 1,059,586 shares of our common stock were still available for future issuance under the ESPP. Unrecognized Compensation Expense As of December 31, 2021, unrecognized share-based compensation expense was as follows: (Dollars in millions) Unrecognized Weighted Average Expected Recognition Period - in Years Stock options $ 18 2.23 Restricted stock awards/units 192 2.62 Total unrecognized share-based compensation expense $ 210 Valuation Assumptions The fair values of share-based awards for employee stock options and employee stock purchases made under our ESPP were estimated using the Black-Scholes option pricing model. The fair values of restricted stock units were based on our closing stock price on the date of grant. The following weighted average assumptions and fair values were used for our employee stock options and restricted stock units: Equity Incentive Plan Awards 2021 2020 2019 Weighted average expected term of options - in years 4.7 4.6 4.6 Weighted average expected volatility of the Company's underlying common stock 43.5 % 41.9 % 35.5 % Risk-free interest rate 0.85 0.37 2.26 Expected dividend yield — — — Weighted average grant date fair value - stock options $ 224.63 $ 66.44 $ 83.50 Weighted average grant date fair value - restricted stock units 554.32 199.51 243.65 The following weighted average assumptions and fair values were used for our ESPP: ESPP 2021 2020 2019 Expected term in years 0.5 0.5 0.5 Weighted average expected volatility of the Company's underlying common stock 36.2 % 51.9 % 38.1 % Risk-free interest rate 0.08 1.12 2.40 Expected dividend yield — — — Weighted average grant date fair value $ 108.83 $ 69.54 $ 52.90 The expected term is based on the implied term of the stock options using factors based on historical exercise behavior. The expected volatilities are based on a blended rate consisting of our historic volatility and our expected volatility over a five-year term which is an indicator of expected volatility and future stock price trends. For 2021, 2020 and 2019, expected volatilities for the ESPP were equal to the historical volatility for the previous six-month periods. The expected risk-free interest rates were based on the yields of U.S. Treasury securities, as reported by the FRB of New York, with maturities equal to the expected terms of the employee stock options.

Investments In Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities Our involvement with VIEs includes our investments in venture capital and private equity funds, debt funds, private and public portfolio companies, investments in qualified affordable housing projects and subordinated debt instruments. The following table presents the carrying amounts and classification of significant variable interests in consolidated and unconsolidated VIEs as of December 31, 2021 and December 31, 2020: (Dollars in millions) Consolidated VIEs Unconsolidated VIEs Maximum Exposure to Loss in Unconsolidated VIEs December 31, 2021: Assets: Cash and cash equivalents $ 13 $ — $ — Non-marketable and other equity securities (1) 768 1,233 1,233 AIR and other assets (2) 31 6 — Total assets $ 812 $ 1,239 $ 1,233 Liabilities: Other liabilities (1) $ 18 $ 482 $ — Long term debt (2) — 90 — Total liabilities $ 18 $ 572 $ — December 31, 2020: Assets: Cash and cash equivalents $ 15 $ — $ — Non-marketable and other equity securities (1) 422 859 859 AIR and other assets 1 — — Total assets $ 438 $ 859 $ 859 Liabilities: Other liabilities (1) $ 1 $ 370 $ — Total liabilities $ 1 $ 370 $ — (1) Included in our unconsolidated non-marketable and other equity securities portfolio at December 31, 2021 and December 31, 2020 are investments in qualified affordable housing projects of $954 million and $616 million, respectively, and related other liabilities consisting of unfunded commitments of $482 million and $370 million, respectively. (2) Included in our unconsolidated accrued interest receivable and other assets at December 31, 2021 are investments in statutory trusts for junior subordinated debt of $6 million and $90 million is included in long term debt previously issued by Boston Private and assumed in the acquisition. Non-marketable and other equity securities Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, SPD-SVB, debt funds, private and public portfolio companies, including public equity securities held as a result of equity warrant assets exercised and investments in qualified affordable housing projects. A majority of these investments are investments held by SVB Financial in third-party funds in which we do not have controlling or significant variable interests. These investments represent our unconsolidated VIEs in the table above. Our non-marketable and other equity securities portfolio also includes investments from SVB Capital. SVB Capital is the funds management business of SVB Financial Group, which focuses primarily on venture capital investments. The SVB Capital family of funds is comprised of direct venture funds that invest in companies and funds of funds that invest in other venture capital funds. We have a controlling and significant variable interest in three of these SVB Capital funds and consolidate these funds for financial reporting purposes. All investments are generally non-redeemable and distributions are expected to be received through the liquidation of the underlying investments throughout the life of the investment fund. Investments may only be sold or transferred subject to the notice and approval provisions of the underlying investment agreement. Subject to applicable regulatory requirements, including the Volcker Rule, we also make commitments to invest in venture capital and private equity funds. For additional details, see Note 21—“Off-Balance Sheet Arrangements, Guarantees and Other Commitments.” The Bank also has variable interests in low income housing tax credit funds, in connection with fulfilling its responsibilities under the CRA, that are designed to generate a return primarily through the realization of federal tax credits. These investments are typically limited partnerships in which the general partner, other than the Bank, holds the power over significant activities of the VIE; therefore, these investments are not consolidated. For additional information on our investments in qualified affordable housing projects see Note 9—“Investment Securities." As of December 31, 2021, our exposure to loss with respect to the consolidated VIEs is limited to our net assets of $794 million and our exposure to loss for our unconsolidated VIEs is equal to our investment in these assets of $1.2 billion.

Reserves on Deposit with the Federal Reserve Bank and Federal Bank Stock	Reserves on Deposit with the Federal Reserve Bank and Federal Bank Stock As was announced on March 15, 2020, the Federal Reserve board reduced reserve requirement ratios to zero percent which effectively eliminated reserve requirements for all depository institutions effective March 26, 2020. Prior to March 26, 2020, the Bank was required to maintain reserves against customer deposits by keeping balances with the Federal Reserve. The cash balances at the Federal Reserve were classified as cash and cash equivalents. Additionally, as a member of the FHLB and FRB, we are required to hold shares of FHLB and FRB stock under the Bank's borrowing agreement. FHLB and FRB stock are recorded at cost as a component of other assets, and any cash dividends received are recorded as a component of other noninterest income.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	Investment Securities Our investment securities portfolio consists of (i) an AFS securities portfolio and a HTM securities portfolio, both of which represent interest-earning investment securities; and (ii) a non-marketable and other equity securities portfolio, which primarily represents investments managed as part of our funds management business as well as public equity securities held as a result of equity warrant assets exercised. Available-for-Sale Securities The major components of our AFS investment securities portfolio at December 31, 2021 and 2020 are as follows: December 31, 2021 (Dollars in millions) Amortized Unrealized Unrealized Carrying AFS securities, at fair value: U.S. Treasury securities $ 15,799 $ 121 $ (70) $ 15,850 U.S. agency debentures 200 — (4) 196 Foreign government debt securities 61 — — 61 Residential MBS: Agency-issued MBS 8,786 13 (210) 8,589 Agency-issued CMO—fixed rate 988 3 (9) 982 Agency-issued CMBS 1,536 27 (20) 1,543 Total AFS securities $ 27,370 $ 164 $ (313) $ 27,221 December 31, 2020 (Dollars in millions) Amortized Unrealized Unrealized Carrying AFS securities, at fair value: U.S. Treasury securities $ 4,198 $ 272 $ — $ 4,470 U.S. agency debentures 234 4 (1) 237 Foreign government debt securities 24 — — 24 Residential MBS: Agency-issued MBS 13,271 233 (1) 13,503 Agency-issued CMO—fixed rate 8,077 40 (10) 8,107 Agency-issued CMBS 4,441 134 (3) 4,572 Total AFS securities $ 30,245 $ 683 $ (15) $ 30,913 The following table summarizes sale activity of AFS securities as recorded in the line item “Gains on investment securities, net," a component of noninterest income: Year ended December 31, (Dollars in millions) 2021 2020 2019 Sales proceeds $ 1,591 $ 2,654 $ 2,189 Net realized gains and losses: Gross realized gains 31 61 1 Gross realized losses — — (5) Net realized gains (losses) $ 31 $ 61 $ (4) The following tables summarize our AFS securities in an unrealized loss position for which an ACL has not been recorded and summarized into categories of less than 12 months, or 12 months or longer as of December 31, 2021 and 2020: December 31, 2021 Less than 12 months 12 months or longer Total (Dollars in millions) Fair Value of Unrealized Fair Value of Unrealized Fair Value of Unrealized AFS securities, at fair value: U.S. Treasury securities $ 7,777 $ (70) $ — $ — $ 7,777 $ (70) U.S. agency debentures 196 (4) — — 196 (4) Residential MBS: Agency-issued MBS 8,280 (210) — — 8,280 (210) Agency-issued CMO —fixed rate 740 (9) — — 740 (9) Agency-issued CMBS 603 (11) 163 (9) 766 (20) Total AFS securities (1) $ 17,596 $ (304) $ 163 $ (9) $ 17,759 $ (313) (1) As of December 31, 2021, we identified a total of 475 investments that were in unrealized loss positions with 4 investments in unrealized loss positions for a period of time greater than 12 months. Based on our analysis of the securities in an unrealized loss position as of December 31, 2021, the decline in value is unrelated to credit loss and is related to changes in market interest rates since purchase and therefore changes in value for securities are included in other comprehensive income. Market valuations and credit loss analyses on assets in the AFS securities portfolio are reviewed and monitored on a quarterly basis. As of December 31, 2021, we do not intend to sell any of our securities in an unrealized loss position prior to recovery of our amortized cost basis, and it is more likely than not that we will not be required to sell any of our securities prior to recovery of our amortized cost basis. None of the investments in our AFS securities portfolio were past due as of December 31, 2021.

(2) As of December 31, 2020, we identified a total of 93 investments that were in unrealized loss positions, of which no investments are in an unrealized loss position for a period of time greater than 12 months. None of the investments in our AFS securities portfolio were past due as of December 31, 2020. The following table summarizes the fixed income securities, carried at fair value, classified as AFS as of December 31, 2021 by the remaining contractual principal maturities. For U.S. Treasury securities, U.S. agency debentures and foreign government debt securities, the expected maturity is the actual contractual maturity of the notes. Expected maturities for MBS may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. MBS classified as AFS typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments.

The securities re-designated consisted of agency-issued CMO's, CMBS', MBS' and U.S. agency debentures with a total carrying value of $8.8 billion. At the time of re-designation the securities included $132 million of pretax net unrealized losses in other comprehensive income and are being amortized over the life of the securities in a manner consistent with the amortization of a premium or discount. Our decision to re-designate the securities was based on our ability and intent to hold these securities to maturity. Factors used in assessing the ability to hold these securities to maturity were future liquidity needs and sources of funding. HTM securities are carried on the balance sheet at amortized cost and the changes in the value of these securities, other than an ACL, are not reported on the financial statements. The components of our HTM investment securities portfolio at December 31, 2021 and 2020 are as follows: December 31, 2021 (Dollars in millions) Amortized Unrealized Unrealized Fair Value ACL (2) HTM securities, at cost: U.S. agency debentures (1) $ 609 $ 8 $ (2) $ 615 $ — Residential MBS: Agency-issued MBS 64,439 124 (887) 63,676 — Agency-issued CMO—fixed rate 10,226 9 (145) 10,090 — Agency-issued CMO—variable rate 100 1 — 101 — Agency-issued CMBS 14,959 39 (277) 14,721 — Municipal bonds and notes 7,157 185 (27) 7,315 1 Corporate bonds 712 2 (5) 709 6 Total HTM securities $ 98,202 $ 368 $ (1,343) $ 97,227 $ 7 (1) Consists of pools of Small Business Investment Company debentures issued and guaranteed by the SBA, an independent agency of the United States.

Allowance for Credit Losses for HTM Securities For HTM securities, the year ended December 31, 2021 had a beginning ACL balance of less than $1 million, a provision for credit losses of $7 million and an ending ACL balance of $7 million. For the year ended December 31, 2020, the beginning ACL balance, the day one impact of adopting ASC 326, the provision for credit losses and the ending balance of ACL for HTM securities, in each case, were all less than $1 million. Credit Quality Indicators On a quarterly basis, management monitors the credit quality for HTM securities through the use of standard credit ratings. The following table summarizes our amortized cost of HTM securities aggregated by credit quality indicator at December 31, 2021 and December 31, 2020: (Dollars in millions) December 31, 2021 December 31, 2020 Municipal bonds and notes: Aaa $ 3,774 $ 2,070 Aa1 2,031 1,145 Aa2 1,154 420 Aa3 172 — A1 26 — Total municipal bonds and notes $ 7,157 $ 3,635 Corporate bonds: Aaa $ 39 $ — Aa1 — — Aa2 42 — Aa3 105 — A1 251 — A2 264 — A3 11 — Total corporate bonds $ 712 $ — The following table summarizes the remaining contractual principal maturities on fixed income investment securities classified as HTM as of December 31, 2021. For U.S. agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected remaining maturities for certain U.S. agency debentures may occur earlier than their contractual maturities because the note issuers have the right to call outstanding amounts ahead of their contractual maturity. Expected maturities for MBS may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. MBS classified as HTM typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments; however, we expect to collect substantially all of the recorded investment on these securities.

We carry our unconsolidated venture capital and private equity fund investments at fair value based on the fund investments' net asset values per share as obtained from the general partners of the investments. For each fund investment, we adjust the net asset value per share for differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example September 30 th for our December 31 st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period. (3) These investments include direct equity investments in private companies. The carrying value is based on the price at which the investment was acquired plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, exit strategies, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted.

Receivables [Abstract]
Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments	Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments We serve a variety of commercial clients in the private equity/venture capital, technology, life science/healthcare, premium wine and commercial real estate industries. Loans made to private equity/venture capital firm clients typically enable them to fund investments prior to their receipt of funds from capital calls and are reported under the Global Fund Banking class of financing receivable below. Our technology clients generally tend to be in the industries of hardware (such as semiconductors, communications, data, storage and electronics), software/internet (such as infrastructure software, applications, software services, digital content and advertising technology) and climate technology and sustainability. Our life science/healthcare clients primarily tend to be in the industries of biopharma, healthtech, medical devices, healthcare services and diagnostics and tools. Loans to our technology and life science/healthcare clients are reported under the Investor Dependent, Cash Flow Dependent - SLBO and Innovation C&I classes of financing receivable below. We also make commercial and industrial loans, such as working capital lines and term loans for equipment and fixed assets, to clients that are not in the technology and life science/healthcare industries, which are reported in the Other C&I class of financing receivable below. Loans to the premium wine industry focus on vineyards and wineries that produce grapes and wines of high quality. Commercial real estate loans are generally acquisition financing for commercial properties such as office buildings, retail properties, apartment buildings and industrial/warehouse space. In addition to commercial loans, we make consumer loans through SVB Private Bank and provide real estate secured loans to eligible employees through our EHOP. We also provide community development loans made as part of our responsibilities under the CRA. These loans are included within “construction loans” below and are primarily secured by real estate. Additionally, beginning in April 2020, we accepted applications under the PPP administered by the SBA under the CARES Act and originated loans to qualified small businesses. Disbursement of PPP funds under the CARES Act originally expired on August 8, 2020, however, on December 27, 2020, the Economic Aid Act was enacted, which extended the application period for PPP loans up to March 31, 2021, and allowed for certain PPP borrowers to apply for second draw loans. The disbursement phase of the PPP was further extended to June 30, 2021 pursuant to the PPP Extension Act of 2021. Loan Portfolio Segments and Classes of Financing Receivables Upon the completion of the acquisition of Boston Private on July 1, 2021, we modified our portfolio segments and classes of financing receivables to accommodate Boston Private loans. Refer to Note 2 — “Summary of Significant Accounting Policies” for additional information on our current portfolio segments and classes of financing receivables. For the periods presented prior to the acquisition in 2021, the following reclassifications have been made to conform to the current period presentation: • Investor Dependent "Mid Stage" and "Later Stage" loans have been combined and presented as "Growth Stage." • "Cash Flow Dependent - Other" and " Balance Sheet Dependent" loans have been combined and presented as "Innovation C&I." Additionally, refer to Note 3 — “Business Combination” for information regarding the Boston Private acquisition. The composition of loans at amortized cost basis broken out by class of financing receivable at December 31, 2021 and December 31, 2020, respectively, is presented in the following table: December 31, (Dollars in millions) 2021 2020 Global fund banking $ 37,958 $ 25,543 Investor dependent: Early stage 1,593 1,486 Growth stage 3,951 3,486 Total investor dependent 5,544 4,972 Cash flow dependent - SLBO 1,798 1,989 Innovation C&I 6,673 5,136 Private bank (4) 8,743 4,901 CRE (4) 2,670 — Premium wine (4) 985 1,053 Other C&I 1,257 — Other (4) 317 28 PPP 331 1,559 Total loans (1) (2) (3) $ 66,276 $ 45,181 ACL (422) (448) Net loans $ 65,854 $ 44,733 (1) Total loans at amortized cost is net of unearned income of $250 million and $226 million at December 31, 2021 and December 31, 2020, respectively. (2) Included within our total loan portfolio are credit card loans of $583 million and $400 million at December 31, 2021 and December 31, 2020, respectively. (3) Included within our total loan portfolio are construction loans of $367 million and $118 million at December 31, 2021 and December 31, 2020, respectively. (4) Of our total loans, the table below includes those secured by real estate at amortized cost at December 31, 2021 and December 31, 2020 and were comprised of the following: December 31, (Dollars in millions) 2021 2020 Real estate secured loans: Private bank: Loans for personal residence $ 6,939 $ 3,392 Loans to eligible employees 455 481 Home equity lines of credit 130 43 Other 135 143 Total private bank loans secured by real estate $ 7,659 $ 4,059 CRE: Multifamily and residential investment $ 1,021 $ — Retail 524 — Office and medical 499 — Manufacturing, industrial and warehouse 336 — Hospitality 142 — Other 148 — Total CRE loans secured by real estate $ 2,670 $ — Premium wine 793 824 Other 334 57 Total real estate secured loans $ 11,456 $ 4,940 Credit Quality Indicators For each individual client, we establish an internal credit risk rating for that loan, which is used for assessing and monitoring credit risk as well as performance of the loan and the overall portfolio. Our internal credit risk ratings are also used to summarize the risk of loss due to failure by an individual borrower to repay the loan. For our internal credit risk ratings, each individual loan is given a risk rating of 1 through 10. Loans risk-rated 1 through 4 are performing loans and translate to an internal rating of “Pass,” with loans risk-rated 1 being cash secured. Loans risk-rated 5 through 7 are performing loans; however, we consider them as demonstrating higher risk, which requires more frequent review of the individual exposures; these translate to an internal rating of “Criticized.” All of our nonaccrual loans are risk-rated 8 or 9 and are classified under the nonperforming category. Loans rated 10 are charged-off and are not included as part of our loan portfolio balance. We review our credit quality indicators on a quarterly basis for performance and appropriateness of risk ratings as part of our evaluation process for our ACL for loans. The following tables summarize the credit quality indicators, broken out by class of financing receivables and vintage year, as of December 31, 2021 and December 31, 2020.

The Moody's Analytics December 2021 forecast was utilized in our quantitative model for the ACL as of December 31, 2021 for both SVB and Boston Private loans. The forecast assumptions included an improvement in the unemployment rate and a strong forecasted gross domestic product growth rate, both of which were a result of ongoing economic stabilization as the pandemic's impact begins to subside. We determined the forecast to be a reasonable view of the outlook for the economy given the available information at current year end. To the extent we identified credit risk considerations that were not captured by the Moody's Analytics December 2021 forecast, we addressed the risk through management's qualitative adjustments to our ACL. The enhancements made to our reserving model were made in normal course, with the primary enhancements being the addition of two years of portfolio data, more granular prepayment models and the re-selection of macroeconomic variables.

Troubled Debt Restructurings As of December 31, 2021, we had 62 TDRs with a total carrying value of $96 million where concessions have been granted to borrowers experiencing financial difficulties in an attempt to maximize collection. There were no unfunded commitments available for funding to the clients associated with these TDRs as of December 31, 2021.

(2) Loans modified in TDRs during 2021 include $33 million of loans acquired from Boston Private that were modified in TDRs. (3) There were $6 million, $31 million and $11 million of partial charge-offs during 2021, 2020 and 2019, respectively. During 2021, $31 million of new TDRs were modified through payment deferrals granted to our clients, $2 million were modified through interest rate reductions, $2 million were modified through settlements, and $22 million were modified through a combination of the above. During 2020, $55 million of new TDRs were modified through payment deferrals and $1 million were modified through partial forgiveness of principal. During 2019, new TDRs of $87 million were modified through payment deferrals and $3 million were modified through partial forgiveness of principal. The following table summarizes the recorded investment in loans modified in TDRs within the previous 12 months that subsequently defaulted during 2021, 2020 and 2019: Year ended December 31, (Dollars in millions) 2021 2020 2019 TDRs modified within the previous 12 months that defaulted during the period: Investor dependent Growth stage $ — $ — $ 11 Total investor dependent — — 11 Cash flow dependent - SLBO — — 37 Premium wine — 1 — Total TDRs modified within the previous 12 months that defaulted in the period (1) $ — $ 1 $ 48 (1) For the years ended December 31, 2021 and December 31, 2020, loan amounts are disclosed using the amortized cost basis as a result of the adoption of CECL. Loan amounts for the year ended December 31, 2019, are disclosed using the gross basis in accordance with the previous methodology. Charge-offs and defaults on previously restructured loans are evaluated to determine the impact to the ACL for loans, if any. The evaluation of these defaults may impact the assumptions used in calculating the reserve on other TDRs and nonaccrual loans as well as management’s overall outlook of macroeconomic factors that affect the reserve on the loan portfolio as a whole. After evaluating the charge-offs and defaults experienced on our TDRs we determined that no change to our reserving methodology for TDRs was necessary to determine the ACL for loans as of December 31, 2021. Allowance for Credit Losses: Unfunded Credit Commitments We maintain a separate ACL for unfunded credit commitments that is determined using a methodology that is inherently similar to the methodology used for calculating the ACL for loans. At December 31, 2021 , our ACL estimates utilized the Moody's economic forecasts from December 2021 as described above. The ACL for unfunded commitments increased by $50 million from the prior year, driven primarily by growth in our ou tstanding commitments and compositional changes in our portfolio. The following table summarizes the activity relating to our ACL for unfunded credit commitments for 2021, 2020 and 2019: December 31, (Dollars in millions) 2021 2020 2019 ACL: unfunded credit commitments, beginning balance $ 121 $ 68 $ 55 Impact of adopting ASC 326 — 23 — Provision for credit losses (1) 50 30 13 ACL: unfunded credit commitments, ending balance (2) $ 171 $ 121 $ 68 (1) The provision for credit losses for unfunded credit commitments for 2021 includes a post-combination initial provision of $2 million related to commitments acquired from Boston Private. (2) The “ACL: unfunded credit commitments” is included as a component of “other liabilities” on our consolidated balance sheets. See Note 21—“Off-Balance Sheet Arrangements, Guarantees and Other Commitments” for additional disclosures related to our commitments to extend credit.

Leases [Abstract]
Leases	Leases We have operating leases for our corporate offices and certain equipment utilized at those properties. We are obligated under a number of noncancelable operating leases for premises and equipment that expire at various dates, through 2030, and in most instances, include options to renew or extend at market rates and terms. Such leases may provide for periodic adjustments of rentals during the term of the lease based on changes in various economic indicators. Total recorded balances for the lease assets and liabilities are as follows: December 31, (Dollars in millions) 2021 2020 Assets: Right-of-use assets - operating leases $ 313 $ 210 Liabilities: Lease liabilities - operating leases 388 259 The components of our lease cost and supplemental cash flow information related to leases for the year ended December 31, 2021 and 2020 were as follows: December 31, (Dollars in millions) 2021 2020 Operating lease cost $ 90 $ 69 Short-term lease cost — 1 Variable lease cost 4 4 Less: sublease income (4) (2) Total lease expense, net $ 90 $ 72 Supplemental cash flows information: Cash paid for amounts included in the measurement of lease liabilities: Cash paid for operating leases $ 66 $ 50 Noncash items during the period: Lease obligations in exchange for obtaining right-of-use assets: Operating leases $ 187 $ 75 The table below presents additional information related to the Company's leases as of December 31, 2021 and 2020: December 31, 2021 2020 Weighted-average remaining term (in years) - operating leases 7.29 6.05 Weighted-average discount rate - operating leases (1) 1.83 % 2.38 % (1) The incremental borrowing rate used to calculate the lease liability was determined based on the facts and circumstances of the economic environment and the Company’s credit standing as of the effective date of ASC 842. Additionally, the total lease term and total lease payments were also considered in determining the rate. Based on these considerations the Company identified credit terms available under its existing credit lines which represent a collateralized borrowing rate that has varying credit terms that could be matched to total lease terms and total lease payments in ultimately determining the implied borrowing rate in each lease contract. The following table presents our undiscounted future cash payments for our operating lease liabilities as of December 31, 2021: Years ended December 31, Operating Leases 2022 $ 77 2023 77 2024 62 2025 50 2026 38 2027 and thereafter 112 Total lease payments $ 416 Less: imputed interest (28) Total lease liabilities $ 388 Lease Exits Following the acquisition of Boston Private, we decided to exit various leased office locations during 2021 and market these spaces for sublease. When a company plans to utilize an ROU asset for less than it was initially intended, ASC 842, Leases, requires an evaluation for impairment and disclosure in accordance with ASC 360-10-45-2, Impairment or Disposal of Long-Lived Assets. We have recognized $39 million of impairment charges related to these leased office locations during 2021. We included impairment and lease exit related expenses in the “Merger-related charges” in our Consolidated Statement of Income for the year ended December 31, 2021.

Junior Subordinated Debentures On July 1, 2021, SVB Financial Group assumed two statutory trusts during the merger with Boston Private. These trusts were formed for the purpose of issuing trust preferred securities and investing the proceeds in junior subordinated debentures. These statutory trusts created by legacy Boston Private are not consolidated within the financial statements, however the total junior subordinated debentures payable to the preferred stockholders of statutory trusts are reported as long-term debt in the financial statements. The preferred securities represent an undivided beneficial interest in the assets of the trusts. We own all of the trusts' common securities. The trusts' only assets are the junior subordinated debentures issued to it by Boston Private on substantially the same payment terms as the trusts' preferred securities. Boston Private Capital Trust II Junior Subordinated Debentures ("Trust II") As of December 31, 2021 there are $100 million of trust preferred securities outstanding. The preferred trust securities issued by Trust II pay interest quarterly based on a floating three-month rate of LIBOR plus 1.68% which are cumulative. So long as the Company is not in default in the payment of interest on the junior subordinated debentures, the Company has the right under the indenture to defer payments of interest for up to 20 consecutive quarterly periods. The Company does not currently intend to exercise its right to defer interest payments on the junior debentures issued to Trust II. If the Company defers interest payments, it would be subject to certain restrictions relating to the payment of dividends on or purchases of its capital stock and payments on its debt securities ranking equal with or junior to the junior subordinated debentures. The effective interest rate on the junior subordinated debentures was 1.898%. The junior subordinated debentures will mature on December 30, 2035. As of December 31, 2021, the carrying value of the Company's investment in Trust II was $3 million, which represents the total amount of common securities in such trust. Boston Private Capital Trust I Junior Subordinated Debenture ("Trust I") As of December 31, 2021 there are less than $1 million of the convertible trust preferred securities outstanding. The convertible trust preferred securities issued by Trust I pay interest quarterly and have a fixed distribution rate of 4.875%. The quarterly distributions are cumulative.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We primarily use derivative financial instruments to manage interest rate risk and currency exchange rate risk and to assist customers with their risk management objectives, which may include currency exchange rate risks and interest rate risks. Also, in connection with negotiating credit facilities and certain other services, we often obtain equity warrant assets giving us the right to acquire stock in private, venture-backed companies in the technology and life science/healthcare industries. Interest Rate Risk Interest rate risk is our primary market risk and can result from timing and volume differences in the repricing of our interest rate sensitive assets and liabilities and changes in market interest rates. To manage interest rate risk on our interest rate sensitive assets, we have entered into interest rate swap contracts to hedge against future changes in interest rates. We designate these interest rate swap contracts as fair value and cash flow hedges. Fair Value Hedges To manage interest rate risk on our AFS securities portfolio, we enter into pay-fixed, receive-floating interest rate swap contracts to hedge against exposure to changes in the fair value of the securities resulting from changes in interest rates. We designate these interest rate swap contracts as fair value hedges that qualify for hedge accounting under ASC 815, Derivatives and Hedging ("ASC 815") and have elected to account for a portion of them using the last-of-layer method as outlined in ASC 815. We record the fair value hedges in other assets and other liabilities. For qualifying fair value hedges, both the changes in the fair value of the derivative and the portion of the fair value adjustments associated with the last-of-layer attributable to the hedged risk will be recognized into earnings as they occur. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "investment securities" as part of interest income, a component of consolidated net income. We assess hedge effectiveness under ASC 815 on a quarterly basis to ensure all hedges remain highly effective and hedge accounting under ASC 815 can be applied. In conjunction with the assessment of effectiveness, we assess the hedged item to ensure it is expected to be outstanding at the hedged item’s assumed maturity date and the last-of-layer method of accounting under ASC 815 can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge per ASC 815, any remaining fair value basis adjustments are allocated to the individual assets in the portfolio and amortized into earnings over a period consistent with the amortization of other discounts and premiums associated with the respective assets. As allowed under GAAP, we applied the "shortcut" method of accounting to a portion of our fair value hedges which assumes there is perfect effectiveness. The following table summarizes the amortized cost basis of hedged assets that are designated and qualify as fair value hedges and the cumulative amount of fair value hedging adjustments included in the carrying value that have been recorded on our consolidated balance sheets as of December 31, 2021: December 31, 2021 (Dollars in millions) Amortized Cost Basis of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (2) AFS securities (1) $ 15,260 $ (125) (1) These amounts include the amortized cost basis of closed portfolios used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. At December 31, 2021, the amortized cost basis of the closed portfolios used in these hedging relationships was $11.2 billion, the amounts of the designated hedged items was $6.7 billion and the cumulative basis adjustments associated with these hedging relationships was $83 million. (2) The balance includes $6 million of hedging adjustments on discontinued hedging relationships at December 31, 2021. Cash Flow Hedges To manage interest rate risk on our variable-interest rate loan portfolio, we enter into interest rate swap contracts to hedge against future changes in interest rates by using hedging instruments to lock in future cash inflows that would otherwise be impacted by movements in the market interest rates. We designate these interest rate swap contracts as cash flow hedges that qualify for hedge accounting under ASC 815 and record them in other assets and other liabilities. For qualifying cash flow hedges, changes in the fair value of the derivative are recorded in AOCI and recognized in earnings as the hedged item affects earnings. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "loans" as part of interest income, a component of consolidated net income. We assess hedge effectiveness under ASC 815 on a quarterly basis to ensure all hedges remain highly effective to ensure hedge accounting under ASC 815 can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge per ASC 815, any amounts remaining as gain or loss in AOCI are reclassified into earnings in the line item "loans" as part of interest income, a component of consolidated net income. As of March 31, 2020, all derivatives previously classified as hedges with notional balances totaling $5.0 billion and a net asset fair value of $228 million were terminated. As of December 31, 2021, the total unrealized gains on terminated cash flow hedges remaining in AOCI is $116 million, or $83 million net of tax. The unrealized gains will be reclassified into interest income as the underlying forecasted transactions impact earnings through the original maturity of the hedged forecasted transactions. The total remaining term over which the unrealized gains will be reclassified into earnings is approximately three years. Currency Exchange Risk We enter into foreign exchange forward contracts to economically reduce our foreign exchange exposure risk associated with the net difference between foreign currency denominated assets and liabilities. We do not designate any foreign exchange forward contracts as derivative instruments that qualify for hedge accounting. Gains or losses from changes in currency rates on foreign currency denominated instruments are recorded in the line item "other" as part of noninterest income, a component of consolidated net income. We may experience ineffectiveness in the economic hedging relationship, because the instruments are revalued based upon changes in the currency’s spot rate on the principal value, while the forwards are revalued on a discounted cash flow basis. We record forward agreements in gain positions in other assets and loss positions in other liabilities, while net changes in fair value are recorded in the line item "other" as part of noninterest income, a component of consolidated net income. Other Derivative Instruments Also included in our derivative instruments are equity warrant assets and client forward and option contracts, and client interest rate contracts. For further description of these other derivative instruments, refer to Note 2—“Summary of Significant Accounting Policies.” Counterparty Credit Risk We are exposed to credit risk if counterparties to our derivative contracts do not perform as expected. We mitigate counterparty credit risk through credit approvals, limits, monitoring procedures and obtaining collateral, as appropriate. With respect to measuring counterparty credit risk for derivative instruments, we measure the fair value of a group of financial assets and financial liabilities on a net risk basis by counterparty portfolio. The total notional or contractual amounts and fair value of our derivative financial instruments at December 31, 2021 and December 31, 2020 were as follows: December 31, 2021 December 31, 2020 Notional or Fair Value Notional or Fair Value (Dollars in millions) Derivative Assets (1) Derivative Liabilities (1) Derivative Assets (1) Derivative Liabilities (1) Derivatives designated as hedging instruments: Interest rate risks: Interest rate swaps (2) $ 10,700 $ 18 $ — $ — $ — $ — Interest rate swaps — — — — — — Derivatives not designated as hedging instruments: Currency exchange risks: Foreign exchange forwards and swaps 701 16 — 68 — — Foreign exchange forwards and swaps 62 — 2 567 — 20 Other derivative instruments: Equity warrant assets 322 277 — 253 203 — Client foreign exchange forwards and swaps 8,245 146 — 8,026 215 — Client foreign exchange forwards and swaps 7,764 — 126 7,491 — 188 Client foreign currency options 688 9 — 98 2 — Client foreign currency options 688 — 9 98 — 2 Client interest rate derivatives 2,178 99 — 1,082 68 — Client interest rate derivatives (2) 2,315 — 101 1,251 — 27 Total derivatives not designated as hedging instruments 547 238 488 237 Total derivatives $ 565 $ 238 $ 488 $ 237 (1) Derivative assets and liabilities are included in "accrued interest receivable and other assets " and " other liabilities " , respectively, on our consolidated balance sheets. (2) The amount reported reflects reductions of approximately $112 million of derivative assets and $45 million of derivative liabilities at December 31, 2021 and 2020, respectively, reflecting variation margin treated as settlement of the related derivative fair values for legal and accounting purposes as required by central clearing houses.

Noninterest Income

Noninterest Income	12 Months Ended
Noninterest Income	Dec. 31, 2021
Revenue from Contract with Customer [Abstract]
Noninterest Income	Noninterest Income All of the Company's revenue from contracts with customers within the scope of ASC 606 is recognized within noninterest income. Included below is a summary of noninterest income for the years ended December 31, 2021, 2020 and 2019: Year ended December 31, (Dollars in millions) 2021 2020 2019 Noninterest income: Gains on investment securities, net $ 761 $ 421 $ 135 Gains on equity warrant assets, net 560 237 138 Client investment fees 75 132 182 Wealth management and trust fees 44 — — Foreign exchange fees 262 179 159 Credit card fees 131 98 119 Deposit service charges 112 90 89 Lending related fees 76 57 50 Letters of credit and standby letters of credit fees 51 47 43 Investment banking revenue 459 414 195 Commissions 79 67 56 Other 128 98 55 Total noninterest income $ 2,738 $ 1,840 $ 1,221 Gains on investment securities, net Net gains on investment securities include both gains and losses from our non-marketable and other equity securities, which include public equity securities as a result of exercised equity warrant assets, gains and losses from sales of our AFS debt securities portfolio, when applicable, and carried interest. Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, our China Joint Venture, debt and credit funds, private and public portfolio companies, which include public equity securities held as a result of exercised equity warrant assets and qualified affordable housing projects. We experience variability in the performance of our non-marketable and other equity securities from period to period, which results in net gains or losses on investment securities (both realized and unrealized). This variability is due to a number of factors, including unrealized changes in the values of our investments, changes in the amount of realized gains from distributions, changes in liquidity events and general economic and market conditions. Unrealized gains from non-marketable and other equity securities for any single period are typically driven by valuation changes. The extent to which any unrealized gains or losses will become realized is subject to a variety of factors, including, among other things, the expiration of certain sales restrictions to which these equity securities may be subject to (e.g., lock-up agreements), changes in prevailing market prices, market conditions, the actual sales or distributions of securities, and the timing of such actual sales or distributions, which, to the extent such securities are managed by our managed funds, are subject to our funds' separate discretionary sales/distributions and governance processes. Carried interest is comprised of preferential allocations of profits recognizable when the return on assets of our individual managed fund of funds and direct venture funds exceeds certain performance targets and is payable to us, as the general partners of the managed funds. The carried interest we earn is often shared with employees, who are also members of the general partner entities. We record carried interest on a quarterly basis by measuring fund performance to date versus the performance target. For our unconsolidated managed funds, carried interest is recorded as gains on investment securities, net. For our consolidated managed funds, it is recorded as a component of net income attributable to noncontrolling interests. Carried interest allocated to others is recorded as a component of net income attributable to noncontrolling interests. Any carried interest paid to us (or our employees) may be subject to reversal to the extent fund performance declines to a level where inception to date carried interest is lower than actual payments made by the funds. The limited partnership agreements for our funds provide that carried interest is generally not paid to the general partners until the funds have provided a full return of contributed capital to the limited partners. Accrued, but unpaid carried interest may be subject to reversal to the extent that the fund performance declines to a level where inception-to-date carried interest is less than prior amounts recognized. Carried interest income is accounted for under an ownership model based on ASC 323 — Equity Method of Accounting and ASC 810 — Consolidation. Our AFS securities portfolio is a fixed income investment portfolio that is managed with the objective of earning an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and credit diversification as well as addressing our asset/liability management objectives. Though infrequent, sales of debt securities in our AFS securities portfolio may result in net gains or losses and are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk. Gains on investment securities are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our investment-related activities. A summary of gains and losses on investment securities for 2021, 2020 and 2019 is as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Gains on non-marketable and other equity securities, net $ 730 $ 360 $ 139 Gains (losses) on sales of AFS debt securities, net 31 61 (4) Total gains on investment securities, net $ 761 $ 421 $ 135 Gains on equity warrant assets, net In connection with negotiating credit facilities and certain other services, we often obtain rights to acquire stock in the form of equity warrant assets in primarily private, venture-backed companies in the technology and life science/healthcare industries. Any changes in fair value from the grant date fair value of equity warrant assets will be recognized as increases or decreases to other assets on our balance sheet and as net gains or losses on equity warrant assets, in noninterest income, a component of consolidated net income. Gains on equity warrant assets are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our derivative-related activities. A summary of net gains on equity warrant assets for 2021, 2020 and 2019 is as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Equity warrant assets: Gains on exercises, net $ 446 $ 179 $ 107 Terminations (2) (2) (4) Changes in fair value, net 116 60 35 Total net gains on equity warrant assets $ 560 $ 237 $ 138 Client investment fees Client investment fees include fees earned from discretionary investment management services for substantially all clients, managing clients’ portfolios based on their investment policies, strategies and objectives and investment advisory fees.

Wealth management and trust fees Wealth management and trust fees was a new core fee income line item in the third quarter of 2021 reflective of the acquisition of Boston Private. These fees are earned for providing wealth management, retirement plan advisory, family office, financial planning, trust services and other financial advisory services to clients. The Company’s performance obligation under these contracts is satisfied over time as the services are provided. Fees are recognized monthly based on the average monthly, beginning-of-quarter, or, for a small number of clients, end-of-quarter market value of the Private Bank AUM and the applicable fee rate, depending on the terms of the contracts. Fees are also recognized monthly based either on a fixed fee amount or are based on the quarter-end (in arrears) market value of the Private Bank AUM and the applicable fee rate, depending on the terms of the contracts. No performance-based incentives are earned under wealth management contracts. Receivables are recorded on the Consolidated Balance Sheets in the "Accrued interest receivable and other assets" line item. Trust fees are earned when the Company is appointed as trustee for clients. As trustee, the Company administers the client’s trust and manages the assets of the trust, including investments and property. The Company’s performance obligation under these agreements is satisfied over time as the administration and management services are provided. Fees are recognized monthly or, in certain circumstances, quarterly based on a percentage of the market value of the account as outlined in the agreement. Payment frequency is defined in the individual contracts, which primarily stipulate that payment be monthly in arrears. No performance-based incentives are earned on trust fee contracts. Receivables are recorded on the Consolidated Balance Sheets in the "Accrued interest receivable and other assets" line item.

Foreign exchange spot contract fees are recognized upon the completion of the single performance obligation, the execution of a spot trade in exchange for a fee. In line with customary business practice, the legal right transfers to the client upon execution of a foreign exchange contract on the trade date, and as such, we currently recognize our fees based on the trade date and the transactions are typically settled within two business days. Forward contract and option premium fees are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our derivative-related activities.

Rewards programs continue to be accounted for under ASC 310 - Receivables . Our performance obligations for merchant service fees are to transmit data and funds between the merchant and the payment network. Credit card interchange and merchant service fees are earned daily upon completion of transaction settlement services.

Fees generated from letters of credit and standby letters of credit are deferred as a component of other liabilities and recognized in noninterest income over the commitment period using the straight-line method, based on the likelihood that the commitment being drawn down will be remote. Letters of credit and standby letters of credit fees are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our lending related activities. Investment banking revenue We earn investment banking revenue from clients for providing services related to securities underwriting, private placements and advisory services on strategic matters such as mergers and acquisitions. Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. Once the offering is completed, the performance obligation has been satisfied; we recognize the applicable management fee as well as the underwriting fee, net of consideration payable to customers. Private placement fees are recognized at the point in time when the private placement is completed, which is generally when the client accepts capital from the fund raise. Advisory fees from mergers and acquisitions engagements are generally recognized at the point in time when the related transaction is completed. Expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other deal-related expenses are expensed as incurred. We have determined that we act as principal in the majority of these transactions and therefore present expenses gross within other operating expenses. A summary of investment banking revenue by instrument type for 2021, 2020 and 2019 is as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Investment banking revenue: Underwriting fees $ 304 $ 353 $ 153 Advisory fees 90 40 38 Private placements and other 65 21 4 Total investment banking revenue $ 459 $ 414 $ 195 Commissions Commissions include commissions received from clients for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price is fixed at the point in time or trade order execution. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis. The Company also earns subscription fees for market intelligence services that are recognized over the period in which they are delivered. Fees received before the subscription period ends is initially recorded as deferred revenue (a contract liability) in other liabilities in our consolidated balance sheet. Commissions are presented in the "Disaggregation of revenue from contracts with customers" table below. Other Other noninterest income primarily includes income from fund management fees, gains from conversion of convertible debt options and service revenue. Fund management fees are comprised of fees charged directly to our managed funds of funds and direct venture funds. Fund management fees are based upon the contractual terms of the limited partnership agreements and are generally recognized as earned over the specified contract period, which is generally equal to the life of the individual fund. Fund management fees are calculated as a percentage of committed capital and collected in advance and are received quarterly. Fund management fees for certain of our limited partnership agreements are calculated as a percentage of distributions made by the funds and revenue is recorded only at the time of a distribution event. As distribution events are not predetermined for these certain funds, management fees are considered variable and constrained under ASC 606. Gains from conversion of convertible debt options represent unrealized valuation gains on loan conversion derivative assets, and realized gains from the conversion of debt instruments, convertible into a third party’s common stock upon a triggering event such as an IPO. Gains from conversion of convertible debt options are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our derivative-related activities. Other service revenue primarily consists of dividend income on FHLB/FRB stock, correspondent bank rebate income, incentive fees related to carried interest and other fee income. We recognize revenue when our performance obligations are met and record revenues on a daily/monthly, quarterly, semi-annual or annual basis. For event driven revenue sources, we recognize revenue when: (i) persuasive evidence of an arrangement exists, (ii) we have performed the service, provided we have no other remaining obligations to the customer, (iii) the fee is fixed or determinable and (iv) collectability is probable.

Income Taxes	Income Taxes The components of our provision for income taxes for 2021, 2020 and 2019 were as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Current provision: Federal $ 435 $ 300 $ 297 State 224 141 132 Deferred expense (benefit): Federal 3 5 (2) State (11) 2 (2) Income tax expense $ 651 $ 448 $ 425 Our effective tax rate is calculated by dividing income tax expense by the sum of income before income tax expense and the net income attributable to noncontrolling interests. The reconciliation between the federal statutory income tax rate and our effective income tax rate for 2021, 2020 and 2019, is as follows: December 31, (Dollars in millions) 2021 2020 2019 Federal statutory income tax rate 21.0 % 21.0 % 21.0 % State income taxes, net of the federal tax effect 7.5 6.8 7.0 Meals and entertainment 0.1 0.1 0.4 Disallowed officers' compensation 0.3 0.2 0.2 FDIC premiums 0.4 0.3 0.2 Share-based compensation expense on incentive stock options and ESPP (1.6) (0.3) (0.6) Qualified affordable housing project tax credits (0.2) (0.5) (0.3) Tax-exempt interest income (1.0) (0.8) (0.6) Other, net (0.3) 0.2 (0.1) Effective income tax rate 26.2 % 27.0 % 27.2 % Deferred tax assets and liabilities at December 31, 2021 and December 31, 2020, consisted of the following: December 31, (Dollars in millions) 2021 2020 Deferred tax assets: Allowance for credit losses $ 170 $ 158 Share-based compensation expense 26 16 State income taxes 24 17 Accrued compensation 77 44 Loans and debt securities 113 — Lease liability 105 70 Other accruals 19 10 Net operating loss 7 7 Goodwill and intangibles — 3 Foreign tax credit carryforward — 9 SBA loan fees 3 6 Other 10 8 Deferred tax assets 554 348 Valuation allowance (7) (7) Net deferred tax assets after valuation allowance 547 341 Deferred tax liabilities: Derivative equity warrant assets (82) (71) Net unrealized gains on cash flow hedge derivatives (33) (50) Net unrealized gains on AFS debt securities — (186) Non-marketable and other equity securities (219) (119) Premises and equipment (41) (24) Right-of-use asset and deferred rent assets (81) (52) Goodwill and intangibles (24) — Contingent payments (9) — Merger-related fair value adjustments (28) — Other (6) (11) Deferred tax liabilities (523) (513) Net deferred tax assets (liabilities) $ 24 $ (172) Net Deferred Tax Assets U.S. federal net operating loss carryforwards totaled $1 million and $2 million for December 31, 2021 and December 31, 2020. Our foreign net operating loss carryforwards totaled $25 million and $25 million at December 31, 2021 and December 31, 2020, respectively. These net operating loss carryforwards expire at various dates beginning in 2022. Currently, we believe that it is more likely than not that the benefit from the foreign net operating loss carryforwards, which are associated with our Germany and Canada operations, will not be realized in the near term due to uncertainties in the timing of future profitability in the course of business. In recognition of this, we have a valuation allowance of $7 million on the deferred tax assets related to our German and Canadian net operating loss carryforwards as of December 31, 2021. We believe it is more likely than not that the remaining deferred tax assets will be realized against future taxable income. Therefore, no valuation allowance was provided for the remaining deferred tax assets. We are subject to income tax and non-income based taxes by the U.S. federal tax authorities as well as various state and foreign tax authorities. The U.S. federal government and the state of California are major tax filing jurisdictions. We are subject to examination by the IRS and tax authorities in various state, local and foreign tax jurisdictions. The state of California is currently examining the years 2013-2016. Our U.S. federal tax returns remain open to examination for 2018 and subsequent tax years. California tax returns remain open to examination for 2017 and subsequent tax years. At December 31, 2021, our unrecognized tax benefit was $37 million, the recognition of which would reduce our income tax expense by $30 million. We are unable to estimate the unrecognized tax benefit that will materially change in the next 12 months. We recognize interest and penalties related to income tax matters as part of income before income taxes. Interest and penalties were not material for the years ended December 31, 2021, 2020 and 2019. A summary of changes in our unrecognized tax benefit (including interest and penalties) for December 31, 2021, 2020 and 2019 is as follows: (Dollars in millions) Reconciliation of Unrecognized Tax Benefit Interest and Penalties Total Balance at December 31, 2018 $ 13 $ 1 $ 14 Additions for tax positions for current year 4 — 4 Additions for tax positions for prior years — 1 1 Reduction for tax positions for prior years (1) — (1) Lapse of the applicable statute of limitations (2) (1) (3) Reduction as a result of settlement (1) — (1) Balance at December 31, 2019 $ 13 $ 1 $ 14 Additions for tax positions for current year 5 — 5 Additions for tax positions for prior years 1 1 2 Reduction for tax positions for prior years (1) — (1) Lapse of the applicable statute of limitations (1) — (1) Reduction as a result of settlement (1) — (1) Balance at December 31, 2020 $ 16 $ 2 $ 18 Additions for tax positions for current year 21 — 21 Additions for tax positions for prior years — 1 1 Reduction for tax positions for prior years — — — Lapse of the applicable statute of limitations — — — Reduction as a result of settlement — — — Balance at December 31, 2021 $ 37 $ 3 $ 40

The 2006 Incentive Plan and the ESPP are described in Note 5—“Share-Based Compensation.” A summary of expenses incurred under certain employee compensation and benefit plans for 2021, 2020 and 2019 is as follows: Year ended December 31, (Dollars in millions) 2021 2020 2019 Incentive Compensation Plan $ 352 $ 193 $ 144 Direct Drive Incentive Compensation Plan 64 38 37 Warrant Incentive Plan 71 34 15 SVBFG 401(k) Plan 40 30 26 SVBFG ESOP 14 6 4 SVB Securities Incentive Compensation Plan 366 233 107 SVB Securities Retention Award 10 13 12 Incentive Compensation Plan Our ICP is an annual cash incentive plan that rewards performance based on our financial results and other performance criteria. Awards are made based on company performance, the employee's target bonus level and management's assessment of individual employee performance. Direct Drive Incentive Compensation Plan The Direct Drive Incentive Compensation Plan (“Direct Drive”) is an annual sales cash incentive program. Awards are based on sales teams' performance as to predetermined financial targets and other company/individual performance criteria. Actual awards for each sales team member under Direct Drive are based on: (i) the actual results and financial performance with respect to the incentive gross profit targets; (ii) the sales team payout targets; and (iii) the sales team member's sales position and team payout allocation. Warrant Incentive Plan The Warrant Incentive Plan provides individual and team awards to those employees who negotiate warrants on our behalf. Designated participants, as determined by the Company, share in the cash proceeds received by the Company from the exercise of equity warrant assets. Deferred Compensation Plan Under the Deferred Compensation Plan (the “DC Plan”), eligible employees may elect to defer up to 50 percent of their base salary and/or up to 100 percent of any eligible bonus payment earned during the plan year. Any amounts deferred under the DC Plan will be invested and administered by us (or such person we designate). We generally do not match employee deferrals to the DC Plan. From time to time, we may also offer deferred special retention incentives and employer contributions under this plan to key plan participants. The deferred incentives and employer contributions are eligible for investment in the DC Plan during the retention qualifying period or vesting period. Voluntary deferrals under the DC Plan were $8 million, $6 million and $7 million in 2021, 2020 and 2019, respectively. The DC Plan overall, had investment gains of $7 million, gains of $8 million and losses of $7 million in 2021, 2020 and 2019, respectively. 401(k) and ESOP The 401(k) Plan and ESOP, collectively referred to as the “Plan”, is a combined 401(k) tax-deferred savings plan and employee stock ownership plan in which most regular U.S. employees are eligible to participate. Employees participating in the 401(k) Plan are allowed to contribute up to 75 percent of their pre-tax pay as defined in the Plan, up to the maximum annual amount allowable under federal income tax regulations of $20,500 for December 31, 2021, $19,500 for 2020, and $19,000 for 2019. We match the employee's contributions dollar-for-dollar, up to five percent of the employee's pre-tax pay as defined in the Plan. Our matching contributions vest immediately. The amount of salary deferred, up to the allowed maximum, is not subject to federal or state income taxes at the time of deferral. Discretionary ESOP and profit-sharing contributions, based on our company performance, are made by us to all eligible individuals employed by us on the last day of the fiscal year. We may elect to contribute cash or our common stock (or a combination of cash and stock), in an amount not exceeding ten percent of the employee's eligible pay earned in the fiscal year. The ESOP and/or profit-sharing contributions vest in equal annual increments over a participant's first five years of service (thereafter, all subsequent ESOP and/or profit-sharing contributions are fully vested). For 2021, 2020 and 2019, 6,100, 12,094 and 14,442 shares, respectively, were allocated to participants in the ESOP. SVB Securities Incentive Compensation Plan Our SVB Securities Incentive Compensation Plan is an annual cash incentive plan that rewards performance of SVB Securities employees based on SVB Securities' financial results. This plan requires employees who exceed certain compensation levels to defer a portion of their compensation, of which, 25% will be settled in the form of restricted stock units and 75% will be settled in the form of cash. The deferred compensation vests over a period of up to five years. SVB Securities Retention Award The SVB Securities Retention Award is an incentive award that granted designated SVB Securities employees restricted stock awards and cash after the close of the acquisition of SVB Securities in January 2019. The aggregate amount of the awards was $60 million, of which 50% will be settled in the form of cash and 50% in the form of restricted stock awards. The awards vest in equal annual increments over five years. EHOP Program five seven

Commitments and Contingencies Disclosure [Abstract]
Off-Balance Sheet Arrangements, Guarantees and Other Commitments	Off-Balance Sheet Arrangements, Guarantees and Other Commitments In the normal course of business, we use financial instruments with off-balance sheet risk to meet the financing needs of our customers. These financial instruments include commitments to extend credit, standby letters of credit and commitments to invest in venture capital and private equity fund investments. These instruments involve, to varying degrees, elements of credit risk. Credit risk is defined as the possibility of sustaining a loss because other parties to the financial instrument fail to perform in accordance with the terms of the contract. Commitments to Extend Credit A commitment to extend credit is a formal agreement to lend funds to a client as long as there is no violation of any condition established in the agreement. Such commitments generally have fixed expiration dates, or other termination clauses, and usually require a fee paid by the client upon us issuing the commitment. The following table summarizes information related to our commitments to extend credit at December 31, 2021 and December 31, 2020, respectively: December 31, (Dollars in millions) 2021 2020 Loan commitments (1) $ 40,327 $ 28,975 Standby letters of credit (2) 3,612 3,003 Commercial letters of credit (3) 77 4 Total unfunded credit commitments $ 44,016 $ 31,982 Allowance for unfunded credit commitments (4) 171 121 (1) Represents commitments which are available for funding, due to clients meeting all collateral, compliance and financial covenants required under loan commitment agreements. (2) See below for additional information on guarantees under our standby letters of credit. (3) Commercial letters of credit are issued primarily for inventory purchases by a client and are typically short-term in nature. (4) Our allowance for credit losses for unfunded credit commitments includes an allowance for both our unfunded loan commitments and our letters of credit. Our potential exposure to credit loss for commitments to extend credit, in the event of nonperformance by the other party to the financial instrument, is the contractual amount of the available unused loan commitment. We use the same credit approval and monitoring process in extending credit commitments as we do in making loans. The actual liquidity needs and the credit risk that we have experienced have historically been lower than the contractual amount of commitments to extend credit because a significant portion of these commitments expire without being drawn upon. We evaluate each potential borrower and the necessary collateral on an individual basis. The type of collateral varies, but may include real property, intellectual property, bank deposits or business and personal assets. The credit risk associated with these commitments is considered in the allowance for unfunded credit commitments. Standby Letters of Credit Standby letters of credit represent conditional commitments issued by us on behalf of a client to guarantee the performance of the client to a third party when certain specified future events have occurred. We provide two types of standby letters of credit: performance and financial standby letters of credit. Performance standby letters of credit are issued to guarantee the performance of a client to a third party when certain specified future events have occurred and are primarily used to support performance instruments such as bid bonds, performance bonds, lease obligations, repayment of loans and past due notices. Financial standby letters of credit are conditional commitments issued by us to guarantee the payment by a client to a third party (beneficiary) and are primarily used to support many types of domestic and international payments. These standby letters of credit have fixed expiration dates and generally require a fee to be paid by the client at the time we issue the commitment. The credit risk involved in issuing letters of credit is essentially the same as that involved with extending credit commitments to clients, and accordingly, we use a credit evaluation process and collateral requirements similar to those for credit commitments. When necessary, our standby letters of credit often are cash secured by our clients. The actual liquidity needs and the credit risk that we have experienced historically have been lower than the contractual amount of letters of credit issued because a significant portion of these conditional commitments expire without being drawn upon. The table below summarizes our standby letters of credit at December 31, 2021. The maximum potential amount of future payments represents the amount that could be remitted under these letters of credit if there were a total default by the guaranteed parties, without consideration of possible recoveries under recourse provisions or from the collateral held or pledged.

Commitments to Invest in Venture Capital and Private Equity Funds We make commitments to invest in venture capital and private equity funds, which generally makes investments in privately-held companies. Commitments to invest in these funds are generally made for a 10-year period from the inception of the fund. Although the limited partnership agreements governing these investments typically do not restrict the general partners from calling 100% of committed capital in one year, it is customary for these funds to call most of the capital commitments over 5 to 7 years, and in certain cases, the funds may not call 100% of committed capital. The actual timing of future cash requirements to fund these commitments is generally dependent upon the investment cycle, overall market conditions, and the nature and type of industry in which the privately held companies operate.

At December 31, 2021, the weighted average contractual remaining term was 6.6 years, compared to our estimated remaining life of 2.6 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption. During 2021, 2020 and 2019, we did not have any transfers between Level 3 and Level 1. All other transfers from Level 3 to Level 2 during 2021, 2020 and 2019 were due to the transfer of equity warrant assets from our private portfolio to our public portfolio (see our Level 3 reconciliation above). Financial Instruments not Carried at Fair Value FASB guidance over financial instruments requires that we disclose estimated fair values for our financial instruments not carried at fair value. The following fair value hierarchy table presents the estimated fair values of our financial instruments that are not carried at fair value at December 31, 2021 and 2020: Estimated Fair Value (Dollars in millions) Carrying Amount Total Level 1 Level 2 Level 3 December 31, 2021: Financial assets: Cash and cash equivalents $ 14,619 $ 14,619 $ 14,619 $ — $ — HTM securities 98,195 97,227 — 97,227 — Non-marketable securities not measured at net asset value 424 424 — — 424 Non-marketable securities measured at net asset value 710 710 — — — Net Loans 65,854 67,335 — — 67,335 FHLB and FRB stock 107 107 — — 107 Financial liabilities: Short-term borrowings 121 121 — 121 — Non-maturity deposits (1) 187,464 187,464 187,464 — — Time deposits 1,739 1,728 — 1,728 — 3.50% Senior Notes due 2025 349 370 — 370 — 3.125% Senior Notes due 2030 496 526 — 526 — 1.800% Senior Notes due 2031 494 474 — 474 — 2.100% Senior Notes due 2028 496 501 — 501 — 1.800% Senior Notes due 2026 645 649 — 649 — Junior subordinated debentures 90 92 — 92 — Off-balance sheet financial assets: Commitments to extend credit — 47 — — 47 December 31, 2020: Financial assets: Cash and cash equivalents $ 17,675 $ 17,675 $ 17,675 $ — $ — HTM securities 16,592 17,217 — 17,217 — Non-marketable securities not measured at net asset value 241 241 — — 241 Non-marketable securities measured at net asset value 390 390 — — — Net loans 44,734 45,324 — — 45,324 FHLB and FRB stock 61 61 — — 61 Financial liabilities: Short-term borrowings 21 21 — 21 — Non-maturity deposits (1) 101,294 101,294 101,294 — — Time deposits 688 502 — 502 — 3.50% Senior Notes 349 383 — 383 — 3.125% senior Notes 495 564 — 564 — Off-balance sheet financial assets: Commitments to extend credit — 37 — — 37 (1) Includes noninterest-bearing demand deposits, interest-bearing checking accounts, money market accounts and interest-bearing sweep deposits. Investments in Entities that Calculate Net Asset Value Per Share FASB guidance over certain fund investments requires that we disclose the fair value of funds, significant investment strategies of the investees, redemption features of the investees, restrictions on the ability to sell investments, estimate of the period of time over which the underlying assets are expected to be liquidated by the investee and unfunded commitments related to the investments. Our investments in debt funds and venture capital and private equity fund investments generally cannot be redeemed. Alternatively, we expect distributions, if any, to be received primarily through IPOs and M&A activity of the underlying assets of the fund. Subject to applicable requirements under the Volcker Rule, we do not have any plans to sell any of these fund investments. If we decide to sell these investments in the future, the investee fund’s management must approve of the buyer before the sale of the investments can be completed. The fair values of the fund investments have been estimated using the net asset value per share of the investments, adjusted for any differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example September 30 th , for our December 31 st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period. The following table is a summary of the estimated fair values of these investments and remaining unfunded commitments for each major category of these investments as of December 31, 2021: (Dollars in millions) Carrying Amount Fair Value Unfunded Commitments Non-marketable securities (fair value accounting): Venture capital and private equity fund investments (1) $ 338 $ 338 $ 12 Non-marketable securities (equity method accounting): Venture capital and private equity fund investments (2) 670 670 11 Debt funds (2) 5 5 — Other investments (2) 34 34 1 Total $ 1,047 $ 1,047 $ 24 (1) Venture capital and private equity fund investments within non-marketable securities (fair value accounting) include investments made by our managed funds of funds and one of our direct venture funds (consolidated VIEs) and investments in venture capital and private equity fund investments (unconsolidated VIEs). Collectively, these investments in venture capital and private equity funds are primarily in U.S. and global technology and life science/healthcare companies. Included in the fair value and unfunded commitments of fund investments under fair value accounting are $94 million and $2 million, respectively, attributable to noncontrolling interests. It is estimated that we will receive distributions from the fund investments over the next 10 to 13 years, depending on the age of the funds and any potential extensions of terms of the funds. (2) Venture capital and private equity fund investments, debt funds and other fund investments within non-marketable securities (equity method accounting) include funds that invest in or lend money to primarily U.S. and global technology and life science/healthcare companies. It is estimated that we will receive distributions from the funds over the next 5 to 8 years, depending on the age of the funds and any potential extensions of the terms of the funds.

Banking and Thrift, Other Disclosures [Abstract]
Regulatory Matters	Regulatory Matters SVB Financial and the Bank are subject to various regulatory capital adequacy requirements administered by the Federal Reserve Board and the DFPI. The Federal Deposit Insurance Corporation Improvement Act of 1991 additionally requires that the federal regulatory agencies adopt regulations defining five capital categories for banks: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. We are also subject to a comprehensive capital framework for U.S. banking organizations established by the federal banking agencies (the “Capital Rules”), which implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. There are three categories of capital under the Capital Rules: CET 1, additional Tier 1 and Tier 2. Pursuant to the Capital Rules, the minimum capital ratios applicable to SVB Financial and the Bank are as follows: • 4.5% CET 1 capital to risk-weighted assets; • 6.0% Tier 1 capital (CET 1 plus Additional Tier 1 capital) to risk-weighted assets; • 8.0% Total capital (Tier 1 plus Tier 2 capital) to risk-weighted assets; and • 4.0% Tier 1 capital to average consolidated assets (the “leverage ratio”). We must also meet a 2.5% “buffer” of CET 1 capital to avoid constraints on capital distributions, such as dividends and equity repurchases, and certain bonus compensation for executive officers. The severity of the constraints would depend on the amount of the shortfall and the banking organization’s “eligible retained income”. As of December 31, 2021, both SVB Financial and the Bank exceed the required ratios under the Capital Rules and were considered “well-capitalized” for purposes of the Federal Reserve’s Regulation Y. The following table presents the capital ratios for the Company and the Bank under federal regulatory guidelines, compared to the minimum regulatory capital requirements, as of December 31, 2021 and December 31, 2020: Capital Ratios Capital Amounts (Dollars in millions) Actual Required Minimum (1) Well Capitalized Minimum Actual Required Minimum (1) Well Capitalized Minimum December 31, 2021: CET1 risk-based capital: SVB Financial 12.09 % 7.0 % N/A $ 12,186 $ 7,057 N/A Bank 14.89 7.0 6.5 14,622 6,875 $ 6,384 Tier 1 risk-based capital: SVB Financial 16.08 8.5 6.0 16,206 8,569 6,049 Bank 14.89 8.5 8.0 14,622 8,348 7,857 Total risk-based capital: SVB Financial 16.58 10.5 10.0 16,712 10,585 10,081 Bank 15.40 10.5 10.0 15,129 10,313 9,821 Tier 1 leverage: SVB Financial 7.93 4.0 N/A 16,206 8,175 N/A Bank 7.24 4.0 5.0 14,622 8,075 10,094 December 31, 2020: CET1 risk-based capital: SVB Financial 11.04 % 7.0 % N/A $ 7,138 $ 4,528 N/A Bank 10.70 7.0 6.5 6,530 4,272 $ 3,967 Tier 1 risk-based capital: SVB Financial 11.89 8.5 6.0 7,692 5,498 3,881 Bank 10.70 8.5 8.0 6,530 5,187 4,882 Total risk-based capital: SVB Financial 12.64 10.5 10.0 8,175 6,791 6,468 Bank 11.49 10.5 10.0 7,014 6,407 6,102 Tier 1 leverage: SVB Financial 7.45 4.0 N/A 7,692 4,129 N/A Bank 6.43 4.0 5.0 6,530 4,060 5,075 N/A "Well-Capitalized Minimum" CET1 risk-based capital and Tier 1 leverage ratios are not formally defined under applicable banking regulations for bank holding companies.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We have four reportable segments for management reporting purposes: GCB, SVB Private Bank, SVB Capital and SVB Securities. The results of our operating segments are based on our internal management reporting process. Our GCB and SVB Private Bank segments primary source of revenue is from NII, which is primarily the difference between interest earned on loans, net of FTP and interest paid on deposits, net of FTP. Accordingly, these segments are reported using NII, net of FTP. FTP is an internal measurement framework designed to assess the financial impact of a financial institution’s sources and uses of funds. It is the mechanism by which an earnings credit is given for deposits raised, and an earnings charge is made for funded loans. FTP is calculated at an instrument level based on account characteristics. We also evaluate performance based on provision for credit losses, noninterest income and noninterest expense, which are presented as components of segment operating profit or loss. In calculating each operating segment’s noninterest expense, we consider the direct costs incurred by the operating segment as well as certain allocated direct costs. As part of this review, we allocate certain corporate overhead costs to a corporate account. We do not allocate income tax expense or the provision for unfunded credit commitments (included in provision for credit losses) to our segments. Additionally, our management reporting model is predicated on average asset balances; therefore, period-end asset balances are not presented for segment reporting purposes. Changes in an individual client’s primary relationship designation have resulted, and in the future may result, in the inclusion of certain clients in different segments in different periods. Unlike financial reporting, which benefits from the comprehensive structure provided by GAAP, our internal management reporting process is highly subjective, as there is no comprehensive, authoritative guidance for management reporting. Our management reporting process measures the performance of our operating segments based on our internal operating structure, which is subject to change from time to time, and is not necessarily comparable with similar information for other financial services companies. For reporting purposes, SVB Financial Group has four operating segments for which we report our financial information: • Global Commercial Bank is comprised of results from the following: ◦ Our Commercial Bank products and services are provided by the Bank and its subsidiaries to commercial clients in key innovation markets. The Bank provides solutions to the financial needs of commercial clients through credit, treasury management, foreign exchange, trade finance and other services. In addition, the Bank and its subsidiaries offer a variety of investment services and solutions to its clients that enable them to effectively manage their assets. ◦ Our Global Fund Banking provides banking products and services primarily to our private equity and venture capital clients. ◦ SVB Wine provides banking products and services to our premium wine industry clients, including vineyard development loans. • SVB Private Bank is the private banking division of the Bank, which now includes the financial results of Boston Private effective July 1, 2021. SVB Private Bank provides a range of personal financial solutions for consumers. Our clients are primarily private equity/venture capital professionals and executive leaders of the innovation companies they support as well as high net worth clients acquired from Boston Private. We offer a customized suite of private banking services, including mortgages, home equity lines of credit, restricted and private stock loans, capital call lines of credit and other secured and unsecured lending products, as well as planning-based financial strategies, wealth management, family office, financial planning, tax planning and trust services. In addition, we provide real estate secured loans to eligible employees through our EHOP. • SVB Capital is the funds management business of SVB Financial Group, which focuses primarily on venture capital investments. SVB Capital manages funds (primarily venture capital funds) on behalf of third-party limited partners and, on a more limited basis, SVB Financial Group. The SVB Capital family of funds is comprised of direct venture funds that invest in companies and funds of funds that invest in other venture capital funds. SVB Capital generates income for the Company primarily from investment returns (including carried interest allocations) and management fees. • SVB Securities is an investment bank focused on the innovation economy and operates as a wholly-owned subsidiary of SVB Financial Group. SVB Securities provides investment banking services across all major sub-sectors of Healthcare and Technology. Healthcare sub-sectors include Biopharma, Digital Health and HealthTech, Healthcare Services, Medical Devices and Tools and Diagnostics. SVB Securities launched Technology investment banking in 2021 and serves numerous Technology sub-sectors including Consumer Internet, Commerce Enablement and Marketing Software, Digital Infrastructure and Tech-Enabled Services, Education Technology, Enterprise Software, Industrial Technology and FinTech. SVB also expanded equity research coverage to include Technology companies with the acquisition of MoffettNathanson LLC in 2021. SVB Securities focuses on four main product and service offerings: Capital Raising, M&A Advisory, Equity Research and Sales and Trading. The summary financial results of our operating segments are presented along with a reconciliation to our consolidated results. Our segment information for 2021, 2020 and 2019 is as follows: (Dollars in millions) Global SVB Private SVB Capital SVB Securities (1) Other Items Total Year ended December 31, 2021 Net interest income $ 2,946 $ 194 $ — $ 1 $ 38 $ 3,179 Provision for credit losses (55) (14) — — (54) (123) Noninterest income 708 56 487 608 879 2,738 Noninterest expense (3) (1,277) (212) (71) (561) (949) (3,070) Income (loss) before income tax expense (4) $ 2,322 $ 24 $ 416 $ 48 $ (86) $ 2,724 Total average loans, amortized cost $ 44,173 $ 8,958 $ — $ — $ 1,416 $ 54,547 Total average assets (5) (6) 141,393 10,140 700 830 12,948 166,011 Total average deposits 138,336 8,645 — — 966 147,947 Year ended December 31, 2020 Net interest income $ 2,025 $ 77 $ — $ 1 $ 54 $ 2,157 Provision for credit losses (166) (21) — — (33) (220) Noninterest income 606 3 226 497 508 1,840 Noninterest expense (3) (1,020) (46) (51) (379) (539) (2,035) Income (loss) before income tax expense (4) $ 1,445 $ 13 $ 175 $ 119 $ (10) $ 1,742 Total average loans, amortized cost $ 31,218 $ 4,196 $ — $ — $ 1,852 $ 37,266 Total average assets (5) (6) 75,034 4,230 437 557 5,534 85,792 Total average deposits 72,127 2,172 — — 717 75,016 Year ended December 31, 2019 Net interest income $ 1,850 $ 51 $ — $ 1 $ 195 $ 2,097 Provision for credit losses (92) (2) — — (13) (107) Noninterest income 638 4 122 264 193 1,221 Noninterest expense (3) (875) (40) (31) (253) (402) (1,601) Income (loss) before income tax expense (4) $ 1,521 $ 13 $ 91 $ 12 $ (27) $ 1,610 Total average loans, amortized cost $ 26,031 $ 3,341 $ — $ — $ 544 $ 29,916 Total average assets (5) 56,043 3,371 405 398 2,995 63,212 Total average deposits 53,054 1,524 — — 479 55,057 (1) GCB’s, SVB Capital’s and SVB Securities' components of NII, noninterest income, noninterest expense and total average assets are shown net of noncontrolling interests for all periods presented. Noncontrolling interest is included within "Other Items." (2) The "Other Items" column reflects the adjustments necessary to reconcile the results of the operating segments to the consolidated financial statements prepared in conformity with GAAP. NII consists primarily of interest earned from our fixed income investment portfolio, net of FTP. Noninterest income consists primarily of gains or losses on equity warrant assets, gains or losses on the sale of AFS securities and gains or losses on equity securities from exercised warrant assets. Noninterest expense consists primarily of expenses associated with corporate support functions such as finance, human resources, marketing, legal and other expenses. (3) The GCB segment includes direct depreciation and amortization of $34 million, $25 million and $20 million for December 31, 2021, December 31, 2020 and December 31, 2019, respectively. (4) The internal reporting model used by management to assess segment performance does not calculate income tax expense by segment. Our effective tax rate is a reasonable approximation of the segment rates. (5) Total average assets equal the greater of total average assets or the sum of total average liabilities and total average stockholders’ equity for each segment to reconcile the results to the consolidated financial statements prepared in conformity with GAAP.

Commitments and Contingencies Disclosure [Abstract]
Legal Matters	Legal Matters Certain lawsuits and claims arising in the ordinary course of business have been filed or are pending against us and/or our affiliates, and we may from time to time be involved in other legal or regulatory proceedings. In accordance with applicable accounting guidance, we establish accruals for all such matters, including expected settlements, when we believe it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. When a loss contingency is not both probable and estimable, we do not establish an accrual. Any such loss estimates are inherently uncertain, based on currently available information and are subject to management’s judgment and various assumptions. Due to the inherent subjectivity of these estimates and unpredictability of outcomes of legal proceedings, any amounts accrued may not represent the ultimate resolution of such matters. To the extent we believe any potential loss relating to such matters may have a material impact on our liquidity, consolidated financial position, results of operations and/or our business as a whole and is reasonably possible but not probable, we aim to disclose information relating to such potential loss. We also aim to disclose information relating to any material potential loss that is probable but not reasonably estimable. In such cases, where reasonably practicable, we aim to provide an estimate of loss or range of potential loss. No disclosures are generally made for any loss contingencies that are deemed to be remote. Based upon information available to us, our review of lawsuits and claims filed or pending against us to date and consultation with our outside legal counsel, we have not recognized a material liability for any such matters, nor do we currently expect that these matters will result in a material liability to the Company. However, the outcome of litigation and other legal and regulatory matters is inherently uncertain, and it is possible that one or more of such matters currently pending or threatened could have an unanticipated material adverse effect on our liquidity, consolidated financial position, results of operations and/or our business as a whole, in the future.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2021
Accounting Policies [Abstract]
Use of Estimates and Assumptions	Use of Estimates and Assumptions The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained. Among the more significant estimates are those that relate to: 1) ACL for loans and for unfunded credit commitments, 2) valuation of non-marketable and other equity securities, 3) valuation of equity warrant assets, 4) goodwill, intangible assets and other purchase accounting related adjustments and 5) income taxes.
Principles of Consolidation and Presentation	Principles of Consolidation and Presentation Our consolidated financial statements include the accounts of SVB Financial Group and consolidated entities. We consolidate entities in which we have a controlling financial interest. Before we determine whether we have a controlling financial interest, we must evaluate whether the entity is a voting interest entity or a variable interest entity ("VIE"). VIEs are entities where investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support and, as a group, lack one of the following characteristics: (a) the power to direct the activities that most significantly impact the entity’s economic performance, (b) the obligation to absorb the expected losses of the entity or (c) the right to receive the expected returns of the entity. We are considered to hold a controlling financial interest in a VIE when we are the primary beneficiary. A primary beneficiary is the party that has both: (a) the power to direct the activities that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses or receive benefits of a VIE that could potentially be significant to a VIE. Generally, the parties that make management and investment decisions, or parties that can unilaterally remove such decision-makers are deemed to have the power to direct the activities of a VIE. When assessing whether we have the obligation to absorb losses or the right to receive benefits from the VIE, we consider all of our economic interests in the VIE, including any fees and other compensation received for providing investment and management services if that compensation is not customary and commensurate with the services provided. Voting interest entities are entities that (a) have sufficient equity to finance their activities and (b) provide the equity investors power to make significant decisions relating to the entity’s operations. For such entities, we have a controlling financial interest if we hold a majority of voting rights.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand, cash balances due from banks, interest-earning deposits, Federal Reserve deposits, federal funds sold, securities purchased under agreements to resell and other short-term investment securities. For the consolidated statements of cash flows, we consider cash equivalents to be investments that are readily convertible to known amounts of cash, so near to their maturity that they present an insignificant risk of change in fair value due to changes in market interest rates, and purchased in conjunction with our cash management activities.
Available-for-Sale and Held-to-Maturity Securities	Available-for-Sale Securities and the Allowance for Credit Losses on Available-for-Sale Securities Our AFS securities portfolio is a fixed income investment portfolio that is managed to earn an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and credit diversification and meeting our asset and liability management objectives. The accretion of discounts and amortization of premiums over the contractual terms of the underlying securities are included in interest income. We use estimates of future principal prepayments when applying the effective interest method to prepayable securities. Unrealized gains and losses on AFS securities, net of applicable taxes, are reported in AOCI, a separate component of SVBFG's stockholders' equity. Impairment losses on AFS securities are recognized through earnings when we intend to sell an AFS security, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost. Additionally, we evaluate whether a credit loss exists for securities that we intend to hold. We consider all factors in determining whether a credit loss exists, including the period over which the debt security is expected to recover. A credit impairment is recognized through a valuation allowance against the security with an offset through earnings. The allowance is limited to the amount that fair value is less than the amortized cost basis. Held-to-Maturity Securities and the Allowance for Credit Losses on Held-to-Maturity Securities Debt securities purchased with the positive intent and ability to hold to its maturity are classified as HTM securities and are recorded at amortized cost, net of any ACL. Effective January 1, 2020, we measure ECL on HTM securities on a collective basis by major security type and standard credit rating. Certain securities in our HTM securities portfolio are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. With respect to these securities, we consider the risk of credit loss to be zero and, therefore, we do not record an ECL. The estimate of ECL on our HTM securities that are not guaranteed by the U.S. government considers historical credit loss information and severity of loss in the event of default and leverages external data adjusted for current conditions. A reasonable and supportable forecast period of one year is applied, with immediate reversion to long-term average historical loss rates when remaining contractual lives of securities exceed one year. We do not estimate ECL on AIR from HTM securities as AIR is reversed or written off when the full collection of the AIR related to a security becomes doubtful. AIR from HTM securities totaled $225 million at December 31, 2021 and $55 million at December 31, 2020 and is excluded from the amortized cost disclosures within our HTM security disclosures in Note 9—“Investment Securities” as it is included and reported separately within "Accrued interest receivable and other assets" in our consolidated balance sheets. ECL on bonds that do not share common risk characteristics with our collective portfolio are individually measured based on net realizable value, or the difference between the discounted value of the expected future cash flows and the recorded amortized cost basis of the security.
Non-Marketable and Other Securities	Non-Marketable and Other Equity Securities Non-marketable and other equity securities include investments in venture capital and private equity funds, SPD-SVB, debt funds, private and public portfolio companies, including public equity securities held as a result of equity warrant assets exercised, and investments in qualified affordable housing projects. A majority of these investments are managed through our SVB Capital funds business in funds of funds and direct venture funds. Our accounting for investments in non-marketable and other equity securities depends on several factors, including the level of ownership, power to control and the legal structure of the subsidiary making the investment. As further described below, we base our accounting for such securities on: (i) fair value accounting, (ii) measurement alternative for other investments without a readily determinable fair value, (iii) equity
Fair Value Accounting	Fair Value Accounting
Other Investments without a Readily Determinable Fair Value	Other Investments without a Readily Determinable Fair Value Our direct investments in private companies do not have a readily determinable fair value. We measure these investments at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments from the same issuer. Such changes are recognized through earnings. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted. Our investments in unconsolidated funds where we do not have the ability to exercise significant influence over their operating and financial policies are valued using the net asset value as obtained from the general partners of the fund investments because the funds do not have a readily determinable fair value. The general partners of these funds prepare their financial statements using guidance consistent with fair value accounting. We account for differences between our measurement date and the date of the fund investment's net asset value by using the most recent available financial information from the investee general partner, for example September 30th, for our December 31st consolidated financial statements. We adjust the value of our investments for any contributions paid, distributions received from the investment and known significant fund transactions or market events about which we are aware through information provided by the fund managers or from publicly available transaction data during the reporting period. Gains or losses resulting from changes in the net asset value are recorded as gains on investment securities, net, a component of noninterest income.
Equity Method	Equity Method Our equity method non-marketable securities consist of investments in venture capital and private equity funds, privately-held companies, debt funds, and joint ventures. Our equity method non-marketable securities and related accounting policies are described as follows: • Equity securities and investments in limited partnerships, such as preferred or common stock in privately-held companies in which we have the ability to exercise significant influence over the investees' operating and financial policies through voting interests, board involvement or other influence are accounted for under the equity method, and • The Bank's joint venture bank in China (SPD-SVB), for which we have 50 percent ownership, is accounted for under the equity method. We recognize our proportionate share of the results of operations of these equity method investees in our results of operations, based on the most current financial information available from the investee. We review our investments accounted for under the equity method at least quarterly for possible other-than-temporary impairment. Our review typically includes an analysis of facts and circumstances for each investment, the expectations of the investment's future cash flows and capital needs, variability of its business and the company's exit strategy. For our fund investments, we use the net asset value per share as provided by the general partners of the fund investments. We account for differences between our measurement date and the date of the fund investment's net asset value by using the most recent available financial information from the investee general partner, for example September 30 th , for our December 31 st consolidated financial statements. We adjust the value of our investments for any contributions paid, distributions received from the investment, and known significant fund transactions or market events about which we are aware through information provided by the fund managers or from publicly available transaction data during the reporting period. We reduce our investment value when we consider declines in value to be other-than-temporary and recognize the estimated loss as a loss on investment securities, a component of noninterest income.
Proportional Amortization Method	Proportional Amortization Method In order to fulfill our responsibilities under the CRA, we invest as a limited partner in low income housing partnerships that operate qualified affordable housing projects and generate tax benefits, including federal low income housing tax credits, for investors. The partnerships are deemed to be VIEs because they do not have sufficient equity investment at risk and are structured with non-substantive voting rights. We are not the primary beneficiary of the VIEs and do not consolidate them. Our investments in low income housing partnerships are recorded in non-marketable and other equity securities within our investment securities portfolio on the consolidated balance sheet. As a practical expedient, we amortize the investment in proportion to the allocated tax benefits under the proportional amortization method of accounting and present such benefits net of investment amortization in income tax expense.
Loans	Loans are reported at amortized cost which consists of the principal amount outstanding, net of unearned loan fees. Unearned loan fees reflect unamortized deferred loan origination and commitment fees net of unamortized deferred loan origination costs. In addition to cash loan fees, we often obtain equity warrant assets that give us an option to purchase a position in a client company's stock in consideration for providing credit facilities. The grant date fair values of these equity warrant assets are deemed to be loan fees and are deferred as unearned income and recognized as an adjustment of loan yield through loan interest income. The net amount of unearned loan fees is amortized into loan interest income over the contractual terms of the underlying loans and commitments using the constant effective yield method, adjusted for actual loan prepayment experience, or the straight-line method, as applicable.
Allowance for Credit Losses: Loans	The allowance for credit losses for loans considers credit risk and is adjusted by a provision for ECL charged to expense and reduced by the charge-off of loan amounts, net of recoveries. Our allowance for credit losses is an estimate of expected losses inherent with the Company's existing loans at the balance sheet date. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. Loan Portfolio Segments and Classes of Financing Receivables The process to estimate the ECL on loans involves procedures to appropriately consider the unique characteristics of our loan portfolio. Our eight portfolio segments are determined by using the following risk dimensions: (i) underwriting methodology, (ii) industry niche and (iii) life stage. The eight portfolio segments are further disaggregated into eleven classes of financing receivable, or risk-based segments, and represents the level at which credit risk is monitored. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process to estimate ECL. For further information refer to Note 9—“Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments.” Upon completing the acquisition of Boston Private, we evaluated the impact of the acquired loan portfolio on our existing portfolio segments and classes of financing receivables. We have modified both levels of disaggregation to accommodate Boston Private loans. The following provides additional information regarding our portfolio segments and classes of financing receivables: • Global Fund Banking (segment and class) – The vast majority of our GFB portfolio segment consists of capital call lines of credit, the repayment of which is dependent on the payment of capital calls by the underlying limited partner investors in funds managed by certain private equity and venture capital firms. • Investor Dependent (segment) – Loans are made primarily to technology and life science/healthcare companies. These borrowers typically have modest or negative cash flows and rarely have an established record of profitable operations. Repayment of these loans may be dependent upon receipt by borrowers of additional equity financing from venture capital firms or other investors, or in some cases, a successful sale to a third party or an IPO. This portfolio segment is further disaggregated into two classes of financing receivables: ◦ Early-Stage (class) – Loans to pre-revenue, development-stage companies and companies that are in the early phases of commercialization, with revenues of up to $5 million. ◦ Growth Stage (class) – Loans to growth-stage enterprises. We consider companies with revenues between $5 million and $15 million, or pre-revenue clinical-stage biotechnology companies, to be Mid-Stage, and companies with revenues in excess of $15 million to be Later Stage. • Cash Flow Dependent and Innovation C&I (segment) – Loans are made primarily to technology and life science/healthcare companies that are not Investor Dependent, i.e. repayment is not dependent on additional equity financing, a successful sale or an IPO. This portfolio segment consists of two classes of financing receivables: ◦ Cash Flow Dependent – SLBO (class) – Loans are typically used to assist a select group of private equity sponsors with the acquisition of businesses, are larger in size, and repayment is generally dependent upon the cash flows of the combined entities. Acquired companies are typically established, later-stage businesses of scale and characterized by reasonable levels of leverage with loan structures that include meaningful financial covenants. The sponsor’s equity contribution is often 50 percent or more of the acquisition price. ◦ Innovation C&I (class) – Other C&I loans in innovation sectors such as technology and life science/healthcare industries. These loans are dependent on either the borrower’s cash flows or balance sheet for repayment. Cash flow dependent loans require the borrower to maintain cash flow from operations that is sufficient to service all debt. Borrowers must demonstrate normalized cash flow in excess of all fixed charges associated with operating the business. Balance sheet dependent loans include asset-based loans and are structured to require constant current asset coverage (i.e. cash, cash equivalents, accounts receivable, and, to a much lesser extent, inventory) in an amount that exceeds the outstanding debt. The repayment of these arrangements is dependent on the financial condition, and payment ability, of third parties with whom our clients do business. • Private Bank (segment and class) – Loans to our Private Bank clients who are primarily private equity/venture capital professionals and executives in the innovation companies as well as high net worth clients acquired from Boston Private. We offer a customized suite of private banking services, including mortgages, home equity lines of credit, restricted and private stock loans, personal capital call lines of credit, lines of credit against liquid assets and other secured and unsecured lending products. In addition, we provide owner occupied commercial mortgages to Private Bank clients and real estate secured loans to eligible employees through our EHOP. • CRE (segment and class) – Generally acquisition financing loans for commercial properties such as office buildings, retail properties, apartment buildings, and industrial/warehouse space. • Other C&I (segment and class) – Loans that include working capital and revolving lines of credit, as well as term loans for equipment and fixed assets. These loans are primarily to clients that are not in the technology and life sciences/healthcare industries. Additionally, this portfolio segment contains commercial tax-exempt loans to not-for-profit private schools, colleges, public charter schools and other not-for-profit organizations. • Premium Wine and Other (segment) – This portfolio segment consists of two classes of financing receivables: ◦ Premium Wine (class) – Loans to wine producers, vineyards and wine industry or hospitality businesses across the Western United States. A large portion of these loans are secured by real estate collateral such as vineyards and wineries. ◦ Other (class) – Primarily construction and land loans for financing new developments as well as financing for improvements to existing buildings. These also include our community development loans made as part of our responsibilities under the CRA. • PPP (segment and class) – Combined loans issued through the PPP. These loans represent clients across all portfolio segments and are guaranteed by the SBA. We maintain a systematic process for the evaluation of individual loans and portfolio segments for inherent risk of estimated credit losses for loans. At the time of approval, each loan in our portfolio is assigned a credit risk rating. Credit risk ratings are assigned on a scale of 1 to 10, with 1 representing loans with a low risk of nonpayment, 9 representing loans with the highest risk of nonpayment and 10 representing loans which have been charged-off. The credit risk ratings for each loan are monitored and updated on an ongoing basis. This credit risk rating process includes, but is not limited to, consideration of such factors as payment status, the financial condition and operating performance of the borrower, borrower compliance with loan covenants, underlying collateral values and performance trends, the degree of access to additional capital, the presence of credit enhancements such as third party guarantees (where applicable), the degree to which the borrower is sensitive to external factors and the depth and experience of the borrower's management team. Our policies require a committee of senior management to review, at least quarterly, credit relationships with a credit risk rating of 5 through 9 that exceed specific dollar values. Expected Credit Loss Measurement The methodology for estimating the amount of ECL reported in the ACL is the sum of two main components: (1) ECL assessed on a collective basis for pools of loans that share similar risk characteristics which includes a qualitative adjustment based on management’s assessment of the risks that may lead to a future loan loss experience different from our historical loan loss experience and (2) ECL assessed for individual loans that do not share similar risk characteristics with other loans. We do not estimate ECL on AIR on loans as AIR is reversed or written off when the full collection of the AIR related to a loan becomes doubtful, which is when loans are placed on nonaccrual status. AIR on loans totaled $171 million at December 31, 2021 and $126 million at December 31, 2020 and is excluded from the amortized cost disclosures in Note 10—“Loans and Allowance for Credit Losses: Loans and Unfunded Credit Commitments”, as it is included and reported separately within "Accrued interest receivable and other assets" in our consolidated balance sheets. While the evaluation process of our ACL on loans uses historical and other objective information, the classification of loans and the estimate of the ACL for loans rely on the judgment and experience of our management. A committee comprised of senior management evaluates the appropriateness of the ACL for loans, which includes review of loan portfolio segmentation, quantitative models, internal and external data inputs, economic forecasts, credit risk ratings and qualitative adjustments. Loans That Share Similar Risk Characteristics with Other Loans We derive an estimated ECL assumption from a non-discounted cash flow approach based on our portfolio segments discussed above. This approach incorporates a calculation of three predictive metrics: (1) PD, (2) LGD and (3) EAD, over the estimated life of the exposure. PD and LGD assumptions are developed based on quantitative models and inherent risk of credit loss, both of which involve significant judgment. Renewals and extensions within our control are not considered in the estimated contractual term of a loan. However, we include potential extensions if management has a reasonable expectation that we will execute a TDR with the borrower. The quantitative models are based on historical credit loss experience, adjusted for probability-weighted economic scenarios. These scenarios are used to support a reasonable and supportable forecast period of three years for all portfolio segments. To the extent the remaining contractual lives of loans in the portfolio extend beyond this three-year period, we revert to historical averages using an autoregressive method of mean reversion that will continue to gradually trend towards the mean historical loss over the remaining contractual lives of loans, adjusted for prepayments. The macroeconomic scenarios are reviewed on a quarterly basis. We also apply a qualitative factor adjustment to the results obtained through our quantitative ECL models to consider model imprecision, emerging risk assessments, trends and other subjective factors that may not be adequately represented in quantitative ECL models. These adjustments to historical loss information are for asset specific risk characteristics, and also reflect our assessment of the extent that current conditions and reasonable and supportable forecasts differ from conditions that existed during the period over which historical information was evaluated. These adjustments are aggregated to become our qualitative allocation. Based on our qualitative assessment estimate of changing risks in the lending environment, the qualitative allocation may vary significantly from period to period and may include, but is not limited to, consideration of the following factors: • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; • Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; • Changes in the nature and volume of the portfolio and in the terms of loans; • Changes in the experience, ability and depth of lending management and other relevant staff; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans and the volume and severity of adversely classified or graded loans; • Changes in the quality of our loan review system; • Changes in the value of underlying collateral for collateral-dependent loans; • The existence and effect of any concentrations of credit, and changes in the level of such concentrations; • The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in our existing portfolio; and • The effect of limitations of available data, model imprecision and recent macro-economic factors that may not be reflected in the forecast information. Loans That Do Not Share Similar Risk Characteristics We monitor our loan pools to ensure all assets therein continue to share similar risk characteristics with other financial assets inside the pool. Changes in credit risk, borrower circumstances or the recognition of write-offs may indicate that a loan's risk profile has changed, and the asset should be removed from its current pool. For a loan that does not share risk characteristics with other loans, ECL is measured based on the net realizable value, that is, the difference between the discounted value of the expected future cash flows and the amortized cost basis of the loan. When a loan is collateral-dependent and the repayment is expected to be provided substantially through the operation or sale of the collateral, the ECL is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral will be determined by the most recent appraisal, as adjusted to reflect a reasonable marketing period for the sale of the asset(s) and an estimate of reasonable selling expenses. Collateral-dependent loans will have independent appraisals completed and accepted at least annually.
Allowance for Unfunded Credit Commitments	Allowance for Credit Losses: Unfunded Credit Commitments We maintain a separate ACL for unfunded credit commitments which is included in other liabilities and the related ECL in our provision for credit losses. We estimate the amount of expected losses by using historical trends to calculate a probability of an unfunded credit commitment being funded and derive historical lifetime expected loss factors for each portfolio segment similar to our funded loan ECL. The collectively assessed ECL for unfunded credit commitments also includes the same qualitative allocations applied for our funded loan ECL. For unfunded credit commitments related to loans that do not share similar risk characteristics with other loans, where applicable, a separate estimate of ECL will be included in our total ACL on unfunded credit commitments. Loan commitments that are determined to be unconditionally cancellable by the Company do not require an ACL on unfunded credit commitments.
Uncollectible Loans and Write-offs	Uncollectible Loans and Write-offs Our charge-off policy applies to all loans, regardless of portfolio segment. Commercial loans are considered for a full or partial charge-off in the event that principal or interest is over 180 days past due and the loan lacks sufficient collateral and it is not in the process of collection. Consumer loans are considered for a full or partial charge-off in the event that principal or interest is over 120 days past due and the loan lacks sufficient collateral and it is not in the process of collection. We also consider writing off loans in the event of any of the following circumstances: 1) the loan, or a portion of the loan is deemed uncollectible due to: a) the borrower's inability to make recurring payments, b) material changes in the borrower's financial condition, or c) the expected sale of all or a portion of the borrower's business is insufficient to repay the loan in full, or 2) the loan has been identified for charge-off by regulatory authorities.
Troubled Debt Restructurings	Troubled Debt Restructurings A TDR arises from the modification of a loan where we have granted a concession to the borrower related to the borrower's financial difficulties that we would not have otherwise considered for economic or legal reasons. These concessions may include: (1) deferral of payment for more than an insignificant period of time that does not include sufficient offsetting borrower concessions; (2) interest rate reductions; (3) extension of the maturity date outside of ordinary course extension; (4) principal forgiveness; or (5) reduction of accrued interest. We use the factors in ASC 310-40, Receivables, Troubled Debt Restructurings by Creditors, in analyzing when a borrower is experiencing financial difficulty, and when we have granted a concession, both of which must be present for a restructuring to meet the criteria of a TDR. If we determine that a TDR exists, we measure impairment based on the present value of expected future cash flows discounted at the loan's effective interest rate, except that as a practical expedient, we may also measure impairment based on a loan's observable market price, or the fair value of the collateral less selling costs if the loan is a collateral-dependent loan. In April 2020, we implemented three loan payment deferral programs targeted to assist borrowers who were the most impacted by the COVID-19 pandemic. These programs included relief for venture-backed, private bank and wine borrowers who met certain criteria. For loans modified under these programs, in accordance with the provisions of Section 4013 of the CARES Act, we elected to not apply TDR classifications to borrowers who were current as of December 31, 2019. In addition, for loans that did not meet the CARES Act criteria, we applied the guidance in an interagency statement issued by bank
Nonaccrual Loans	Nonaccrual Loans Loans are generally placed on nonaccrual status when they become 90 days past due as to principal or interest payments (unless the principal and interest are well secured and in the process of collection); or when we have determined, based upon currently known information, that the timely collection of principal or interest is not probable. When a loan is placed on nonaccrual status, the accrued interest and fees are reversed against interest income and the loan is accounted for using the cost recovery method thereafter until qualifying for return to accrual status. For a loan to be returned to accrual status, all delinquent principal and interest must become current in accordance with the terms of the loan agreement and future collection of remaining principal and interest must be deemed probable. We apply a cost recovery method in which all cash received is applied to the loan principal until it has been collected. Under this approach, interest income is recognized after total cash flows received exceed the recorded investment at the date of initial nonaccrual. All of our nonaccrual loans have credit risk ratings of 8 or 9 and are classified under the nonperforming category.
Purchase Credit-Deteriorated Loans	Purchased Credit-Deteriorated Loans Loans acquired where there is evidence of more than insignificant credit deterioration since origination are classified as PCD. We consider various factors in connection with this determination, including past due or nonaccrual status, credit risk rating declines, and any write downs recorded based on the collectability of the asset, among other factors. PCD loans are recorded at their purchase price plus an ECL estimated at the time of acquisition, which represents the amortized cost basis of the asset. The difference between this amortized cost basis and the par value of the loan is the non-credit discount or premium, which is amortized into interest income over the life of the loan. Subsequent increases and decreases in the allowance for credit losses related to purchased loans is recorded as provision expense.
Premises and Equipment	Premises and Equipment Premises and equipment are reported at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or the terms of the related leases, whichever is shorter. The maximum estimated useful lives by asset classification are as follows: Leasehold improvements Lesser of lease term or asset life Furniture and equipment 3-7 years Computer software 3-7 years Computer hardware 3-5 years We capitalize the costs of computer software developed or obtained for internal use, including costs related to developed software, purchased software licenses and certain implementation costs. For property and equipment that is retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in noninterest expense in consolidated net income.
Lease Obligations	Lease Obligations We have entered into leases for real estate and equipment. At the inception of the lease, each lease is evaluated to determine whether the lease will be accounted for as an operating or finance lease. We had no finance lease obligations at December 31, 2021 and December 31, 2020. We have made an accounting policy election not to recognize right-of-use assets and lease liabilities that arise from short-term leases for any class of underlying asset. In addition to excluding short-term leases, we have implemented an accounting policy in which non-lease components are not separated from lease components in the measurement of ROU asset and lease liabilities for all lease contracts. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company reviews ROU assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. ROU assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (“asset group”). The carrying amount of an asset group is not considered recoverable if it exceeds the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If the asset group is determined not to be recoverable, then an impairment charge is recognized in the amount by which the carrying amount of the store asset group exceeds its fair value. The resulting impairment charge, if any, is allocated to the underlying assets on a pro rata basis using their relative carrying amounts.
Business Combinations	Business Combinations Business combinations are accounted for under the acquisition method of accounting. Acquired assets, including separately identifiable intangible assets, and assumed liabilities are recorded at their acquisition-date estimated fair values. The excess of the cost of acquisition over these fair values is recognized as goodwill. During the measurement period, which cannot exceed one year from the acquisition date, changes to estimated fair values are recognized as an adjustment to goodwill. Certain transaction costs are expensed as incurred.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill is not amortized and is subject, at a minimum, to an annual impairment assessment. A quantitative assessment will be completed if we have not recently completed a fair value assessment of the associated reporting unit and compared the assessed fair value of that reporting unit with its carrying amount, including goodwill. Should we be required to calculate the fair value of the reporting unit, we would generally apply a discounted cash flow analysis that uses forecasted performance estimates, and a discount rate leveraging a reporting unit specific capital asset pricing model, which in turn uses assumptions related to market performance and various macroeconomic and reporting unit specific risks. If this quantitative assessment was recently completed and if we deem the estimate to be current and reliable, we will not perform a full quantitative assessment of the reporting unit’s fair value for that reporting period. Instead, we will qualitatively determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. As part of this qualitative analysis we consider macroeconomic factors that might impact the entity’s performance, entity-specific financial performance of the reporting unit, changes in management or strategy and other factors. We will evaluate goodwill for impairment more frequently if circumstances indicate that the fair value of our reporting units is less than their carrying value, including goodwill.
Fair Value Measurements	Fair Value Measurements Our AFS securities, derivative instruments and certain equity securities are financial instruments recorded at fair value on a recurring basis. We make estimates regarding valuation of assets and liabilities measured at fair value in preparing our consolidated financial statements. Fair Value Measurement-Definition and Hierarchy Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (the “exit price”) in an orderly transaction between market participants at the measurement date. There is a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable and on the significance of those inputs in the fair value measurement. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect our estimates about market data and views of market participants. The three levels for measuring fair value are based on the reliability of inputs and are as follows: Level 1 Fair value measurements based on quoted prices in active markets for identical assets or liabilities that we have the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment. Assets utilizing Level 1 inputs include U.S. Treasury securities, foreign government debt securities, exchange-traded equity securities and certain marketable securities accounted for under fair value accounting. Level 2 Fair value measurements based on quoted prices in markets that are not active or for which all significant inputs are observable, directly or indirectly. Valuations for the AFS securities are provided by independent pricing service providers who have experience in valuing these securities and are compared to the average of quoted market prices obtained from independent brokers. We perform a monthly analysis on the values received from third parties so that the prices represent a reasonable estimate of the fair value. The procedures include, but are not limited to, initial and ongoing review of third-party pricing methodologies, review of pricing trends and monitoring of trading volumes. Additional corroboration, such as obtaining a non-binding price from a broker, may be obtained depending on the frequency of trades of the security and the level of liquidity or depth of the market. Prices received from independent brokers represent a reasonable estimate of the fair value and are validated through the use of observable market inputs including comparable trades, yield curve, spreads and, when available, market indices. If we determine that there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. Below is a summary of the significant inputs used for each class of Level 2 assets and liabilities: U.S. agency debentures: Fair value measurements of U.S. agency debentures are based on the characteristics specific to bonds held, such as issuer name, issuance date, coupon rate, maturity date and any applicable issuer call option features. Valuations are based on market spreads relative to similar term benchmark market interest rates, generally U.S. Treasury securities. Agency-issued MBS: Agency-issued MBS are pools of individual conventional mortgage loans underwritten to U.S. agency standards with similar coupon rates, tenor, and other attributes such as geographic location, loan size and origination vintage. Fair value measurements of these securities are based on observable price adjustments relative to benchmark market interest rates taking into consideration estimated loan prepayment speeds. Agency-issued CMO: Agency-issued CMO are structured into classes or tranches with defined cash flow characteristics and are collateralized by U.S. agency-issued mortgage pass-through securities. Fair value measurements of these securities incorporate similar characteristics of mortgage pass-through securities such as coupon rate, tenor, geographic location, loan size and origination vintage, in addition to incorporating the effect of estimated prepayment speeds on the cash flow structure of the class or tranche. These measurements incorporate observable market spreads over an estimated average life after considering the inputs listed above. Agency-issued CMBS: Fair value measurements of these securities are based on spreads to benchmark market interest rates (usually U.S. Treasury rates or rates observable in the swaps market), prepayment speeds, loan default rate assumptions and loan loss severity assumptions on underlying loans. Foreign exchange forward and option contract assets and liabilities: Fair value measurements of these assets and liabilities are priced based on spot and forward foreign currency rates and option volatility assumptions. Interest rate derivative and interest rate swap assets and liabilities: Fair value measurements of interest rate derivatives and interest rate swaps are priced considering the coupon rate of the fixed leg of the contract and the variable coupon rate on the floating leg of the contract. Valuation is based on both spot and forward rates on the swap yield curve and the credit worthiness of the contract counterparty. Other equity securities: Fair value measurements of equity securities of public companies are priced based on quoted market prices less a discount if the securities are subject to certain sales restrictions. Certain sales restriction discounts generally range from 10 percent to 20 percent depending on the duration of the sale restrictions which typically range from three Equity warrant assets (public portfolio): Fair value measurements of equity warrant assets of publicly-traded portfolio companies are valued based on the Black-Scholes option pricing model. The model uses the price of publicly-traded companies (underlying stock price), stated strike prices, warrant expiration dates, the risk-free interest rate and market-observable option volatility assumptions. Level 3 The fair value measurement is derived from valuation techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions we believe market participants would use in pricing the asset. The valuation techniques are consistent with the market approach, income approach or the cost approach used to measure fair value. Below is a summary of the valuation techniques used for each class of Level 3 assets: Venture capital and private equity fund investments not measured at net asset value: Fair value measurements are based on consideration of a range of factors including, but not limited to, the price at which the investment was acquired, the term and nature of the investment, local market conditions, values for comparable securities, and as it relates to the private company, the current and projected operating performance, exit strategies and financing transactions subsequent to the acquisition of the investment. The significant unobservable inputs used in the fair value measurement include the information about each portfolio company, including actual and forecasted results, cash position, recent or planned transactions and market comparable companies. Equity warrant assets (public portfolio): Fair value measurements of equity warrant assets of publicly-traded portfolio companies are valued based on the Black-Scholes option pricing model. The model uses the price of publicly-traded companies (underlying stock price), stated strike prices, warrant expiration dates, the risk-free interest rate and market-observable option volatility assumptions. Modeled asset values are further adjusted by applying a discount of up to 20 percent for certain warrants that have certain sales restrictions or other features that indicate a discount to fair value is warranted. Equity warrant assets (private portfolio): Fair value measurements of equity warrant assets of private portfolio companies are priced based on a Black-Scholes option pricing model to estimate the asset value by using stated strike prices, option expiration dates, risk-free interest rates and option volatility assumptions. Option volatility assumptions used in the Black-Scholes model are based on public market indices whose members operate in similar industries as companies in our private company portfolio. Option expiration dates are modified to account for estimates to actual life relative to stated expiration. Overall model asset values are further adjusted for a general lack of liquidity due to the private nature of the associated underlying company. There is a direct correlation between changes in the volatility and remaining life assumptions in isolation and the fair value measurement while there is an inverse correlation between changes in the liquidity discount assumption and the fair value measurement.
Fee-based Services Revenue Recognition	Fee-based Services Revenue Recognition Refer to Note 17—“Noninterest Income” for our fee-based services revenue recognition policies for our contracts with customers.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Our federal, state and foreign income tax provisions are based upon taxes payable for the current year, current year changes in deferred taxes related to temporary differences between the tax basis and financial statement balances of assets and liabilities, and a reserve for uncertain tax positions. Deferred tax assets and liabilities are included in the consolidated financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. A valuation allowance is provided, when it is determined based upon available evidence, that it is more likely than not that some portion of the deferred tax asset will not be realized. We file a consolidated federal income tax return, and consolidated, combined, or separate state income tax returns as appropriate. Our foreign incorporated subsidiaries file tax returns in the applicable foreign jurisdictions. We record interest and penalties related to unrecognized tax benefits in other noninterest expense, a component of consolidated net income.
Share-Based Compensation	Share-Based CompensationGenerally, for our stock-based awards granted, stock-based compensation expense is amortized on a straight-line basis over the requisite service period, including consideration of vesting conditions and anticipated forfeitures. The service period is reduced for a select number of awards that provide for continued vesting upon retirement if any of the grantees are retirement eligible at the date of grant (or will become retirement eligible during the vesting period). The fair value of stock options is measured using the Black-Scholes option-pricing model and the fair value for restricted stock awards and restricted stock units are based on the quoted price of our common stock on the date of grant.
Earnings Per Share	Earnings Per Share Basic earnings per common share is computed using the weighted average number of common stock shares outstanding during the period. Diluted earnings per common share is computed using the weighted average number of common stock shares and potential common shares outstanding during the period. Potential common shares consist of stock options, ESPP shares and restricted stock units. Common stock equivalent shares are excluded from the computation if the effect is antidilutive.
Derivative Financial Instruments	Derivative Financial Instruments All derivative instruments are recorded on the balance sheet at fair value. The accounting for changes in fair value of a derivative financial instrument depends on whether the derivative financial instrument is designated and qualifies as part of a hedging relationship and, if so, the nature of the hedging activity. Changes in fair value are recognized through earnings for derivatives that do not qualify for hedge accounting treatment, or that have not been designated in a hedging relationship. Cash Flow Hedges For derivative instruments that are designated and qualify as a cash flow hedge, changes in the fair value of the derivative are recorded in AOCI and recognized in earnings as the hedged item affects earnings. To qualify for hedge accounting, a derivative must be highly effective at reducing exposure to the hedged risk. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "loans" as part of interest income, a component of consolidated net income. We assess hedge effectiveness on a quarterly basis to ensure all hedges remain highly effective to ensure hedge accounting can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge, any amounts remaining as gain or loss in AOCI are reclassified into earnings in the line item "loans" as part of interest income, a component of consolidated net income. Fair value hedges For derivative instruments that are designated and qualify as a fair value hedge, both the changes in the fair value of the derivative and the portion of the fair value adjustments associated with the portfolio attributable to the hedged risk will be recognized into earnings as they occur. To qualify for hedge accounting, a derivative must be highly effective at reducing the hedged risk exposure. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "investment securities" as part of interest income, a component of consolidated net income. We assess hedge effectiveness on a quarterly basis to ensure all hedges remain highly effective and hedge accounting can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge, any remaining fair value basis adjustments are allocated to the individual assets in the portfolio and amortized into earnings over a period consistent with the amortization of other discounts and premiums associated with the respective assets. Equity Warrant Assets In connection with negotiated credit facilities and certain other services, we may obtain equity warrant assets giving us the right to acquire stock in primarily private, venture-backed companies in the technology and life science/healthcare industries. We hold these assets for prospective investment gains. We do not use them to hedge any economic risks nor do we use other derivative instruments to hedge economic risks stemming from equity warrant assets. In general, equity warrant assets entitle us to buy a specific number of shares of stock at a specific price within a specific time period. Certain equity warrant assets contain contingent provisions, which adjust the underlying number of shares or purchase price upon the occurrence of specified future events. Substantially all our warrant agreements qualify as derivatives and are reported at fair value as a component of other assets, on our consolidated balance sheet. The grant date fair values of equity warrant assets received in connection with the issuance of a credit facility are deemed to be loan fees and recognized as an adjustment of loan yield through loan interest income. Similar to other loan fees, the yield adjustment related to grant date fair value of warrants is recognized over the life of that credit facility. Any changes in fair value after the grant date are recognized as net gains or losses on equity warrant assets, in noninterest income, a component of consolidated net income. We value our equity warrant assets using a Black-Scholes option pricing model, which incorporates the following significant inputs: • An underlying asset value, which is estimated based on current information available in valuation reports, including any information regarding subsequent rounds of funding or performance of a company. • Stated strike price, which can be adjusted for certain warrants upon the occurrence of subsequent funding rounds or other future events. • Price volatility or risk associated with possible changes in the warrant price. The volatility assumption is based on historical price volatility of publicly traded companies within indices similar in nature to the underlying client companies issuing the warrant. The actual volatility input is based on the mean and median volatility for an individual public company within an index for the past 16 quarters, from which an average volatility was derived. • Actual data on terminations and exercises of our warrants are used as the basis for determining the expected remaining life of the warrants in each financial reporting period. Warrants may be exercised in the event of acquisitions, mergers or IPOs, and cancelled due to events such as bankruptcies, restructuring activities or additional financings. These events cause the expected remaining life assumption to be shorter than the contractual term of the warrants. • The risk-free interest rate is derived from the Treasury yield curve and is calculated based on a weighted average of the risk-free interest rates that correspond closest to the expected remaining life of the warrant. • Other adjustments, including a marketability discount, are estimated based on management's judgment about the general industry environment. • Number of shares and contingencies associated with obtaining warrant positions such as the funding of associated loans. When a company in the portfolio completes an IPO, or is acquired, we may exercise these equity warrant assets for shares or cash. In the event of an exercise for common stock shares, the basis or value in the common stock shares is reclassified from other assets to investment securities on the balance sheet on the latter of the exercise date or corporate action date. The common stock of public companies is classified as non-marketable and other equity securities. Changes in the fair value of the common stock is recorded as gains or losses on investments securities, in noninterest income, a component of consolidated net income. We account for these securities without a readily determinable fair value based on the price at which the investment was acquired plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments, with changes recorded as gains or losses on investment securities, in noninterest income, a component of consolidated net income. Foreign Exchange Forwards and Foreign Currency Option Contracts We enter into foreign exchange forward contracts and foreign currency option contracts with clients involved in international activities, either as the purchaser or seller, depending upon the clients' need. We also enter into an opposite-way forward or option contract with a correspondent bank to economically hedge client contracts to mitigate the fair value risk to us from fluctuations in currency rates. Settlement, credit and operational risks remain. We also enter into forward contracts with correspondent banks to economically hedge currency exposure risk related to certain foreign currency denominated assets and liabilities. These contracts are not designated as hedging instruments and are recorded at fair value in our consolidated balance sheets. The contracts generally have terms of one year or less, although we may have contracts extending for up to five years. Generally, we have not experienced nonperformance on these contracts, have not incurred credit losses and anticipate performance by all counterparties to such agreements. Changes in the fair value of these contracts are recognized in consolidated net income under other noninterest income, a component of noninterest income. Period-end gross positive fair values are recorded in other assets and gross negative fair values are recorded in other liabilities. Interest Rate Contracts
Recent Accounting Pronouncements	Adoption of New Accounting Standards Income Taxes In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12), which is part of the FASB’s initiative to reduce cost and complexity related to accounting for income taxes. ASU 2019-12 eliminates certain exceptions to the general principles of ASC 740, Income Taxes, and simplifies income tax accounting in several areas. We adopted the guidance on January 1, 2021, on a modified retrospective basis. The adoption did not have a material impact on our financial position, results of operations, cash flows or disclosures.
Reclassifications	Reclassifications Certain prior period amounts primarily related to the adoption of the ASU 2016-13 Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments) ("ASU 2016-13" or "CECL") as mentioned above have been reclassified to conform to current period presentations.

Based on our analysis of the securities in an unrealized loss position as of December 31, 2021, the decline in value is unrelated to credit loss and is related to changes in market interest rates since purchase and therefore changes in value for securities are included in other comprehensive income. Market valuations and credit loss analyses on assets in the AFS securities portfolio are reviewed and monitored on a quarterly basis. As of December 31, 2021, we do not intend to sell any of our securities in an unrealized loss position prior to recovery of our amortized cost basis, and it is more likely than not that we will not be required to sell any of our securities prior to recovery of our amortized cost basis. None of the investments in our AFS securities portfolio were past due as of December 31, 2021.

Summary of Remaining Contractual Principal Maturities and Fully Taxable Equivalent Yields on Securities	The following table summarizes the fixed income securities, carried at fair value, classified as AFS as of December 31, 2021 by the remaining contractual principal maturities. For U.S. Treasury securities, U.S. agency debentures and foreign government debt securities, the expected maturity is the actual contractual maturity of the notes. Expected maturities for MBS may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. MBS classified as AFS typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments.

For U.S. agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected remaining maturities for certain U.S. agency debentures may occur earlier than their contractual maturities because the note issuers have the right to call outstanding amounts ahead of their contractual maturity. Expected maturities for MBS may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. MBS classified as HTM typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments; however, we expect to collect substantially all of the recorded investment on these securities.

We carry our unconsolidated venture capital and private equity fund investments at fair value based on the fund investments' net asset values per share as obtained from the general partners of the investments. For each fund investment, we adjust the net asset value per share for differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example September 30 th for our December 31 st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period. (3) These investments include direct equity investments in private companies. The carrying value is based on the price at which the investment was acquired plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, exit strategies, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted.
