Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements reflect the consolidated operations of Insulet Corporation and its subsidiaries. The consolidated financial statements have been prepared in United States dollars, in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements in conformity with GAAP requires management to make use of estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results may differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. Reclassification of Prior Period Amounts Certain reclassifications have been made to prior period amounts to conform to the current period financial statement presentation. A portion of facility costs and certain information technology costs have been allocated from selling, general and administrative to research and development expenses based on square foot and system usage, respectively and certain quality assurance costs were reclassified from research and development expenses to selling, general and administrative expenses. The net impact of these adjustments wa s a $2.6 million and $4.3 million increase to research and development expenses and decrease to selling, general and administrative expenses f or the years ended December 31, 2019 and December 31, 2018 , respectively . There was no change to previously reported operating or net income. Foreign Currency Translation For the foreign subsidiaries of the Company, assets and liabilities are translated into U.S. dollars using exchange rates as of the balance sheet date, and income and expenses are translated using the average exchange rates in effect for the related month. The net effect of these translation adjustments is reported in accumulated other comprehensive loss within stockholders’ equity on the consolidated balance sheet. Net realized and unrealized gains (losses) from foreign currency transactions are included in other income (expense), net in the consolidated statement of income and were $3.2 million, $0.6 million and $1.0 million for the years ended December 31, 2020, 2019 and 2018, respectively. Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of 90 days or less at the time of purchase to be cash equivalents. Cash equivalents include money market mutual funds, commercial paper and U.S. government and agency bonds that are carried at cost, which approximates their fair value. Restricted cash required to be set aside in connection with equipment financings or that serves as collateral for outstanding letters of credit and bank guarantees is included in other assets and cash and cash equivalents on the consolidated balance sheet. Investments in Marketable Securities Short-term and long-term investment securities consist of certificates of deposit, commercial paper, U.S. government and agency bonds and corporate bonds. Theses available-for-sale marketable securities are carried at fair value and unrealized gains and losses are included as a component of accumulated other comprehensive income (loss) in stockholders’ equity on the consolidated balance sheet. Investments with a stated maturity date of more than one year from the balance sheet date and that are not expected to be used in current operations are classified as long-term investments on the consolidated balance sheet. The Company reviews investments for other-than-temporary impairment when the fair value of an investment is less than its amortized cost. If an available-for-sale security is other than temporarily impaired, the loss is included in other income (expense), net in the consolidated statement of income. Accounts Receivable and Allowance for Credit Losses Trade accounts receivable consist of amounts due from third-party payors, customers and intermediaries and are presented at amortized cost. The allowance for credit losses reflects an estimate of losses inherent in the Company’s accounts receivable portfolio determined based on historical experience, specific allowances for known troubled accounts and other available evidence. Accounts receivable are written off when management determines they are uncollectible. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods: Direct Customer Receivables —The Company measures expected credit losses on direct customer receivables using an aging methodology. The risk of loss for direct customer receivables is higher than other portfolios. The Company relies on third-party payors to accept and timely process claims and on direct consumers to have the ability to pay. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and supportable forecasts. Distributor Receivables —The Company measures expected credit losses on distributor receivables using an individual reserve methodology. The risk of loss in this portfolio is low based on the Company’s historical experience. The estimate of expected credit losses considers payment history as well as credit ratings of the distributors, in addition to current conditions and supportable forecasts. National Healthcare System Receivables —The Company measures expected credit losses on national healthcare system receivables using an individual reserve methodology. The risk of loss in this portfolio is low based on the Company’s historical experience. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and supportable forecasts. Inventories Inventories are stated at the lower of cost or net realizable value, with cost determined under the first-in, first-out method. The Company reduces the carrying value of inventories for those items that are potentially excess, obsolete or slow-moving based on changes in customer demand, technology developments or other economic factors in order to state inventories at net realizable value. Factors influencing these adjustments include inventories on hand compared to estimated future usage and sales. Work in process is calculated based upon a buildup of cost based on the stage of production. Manufacturing variances attributable to abnormally low production are expensed in the period incurred. Contract Acquisition Costs The Company incurs commission costs to obtain a contract related to new customer starts. These costs are capitalized as contract assets in other assets, net of the short-term portion included in prepaid and other current assets. Costs to obtain a contract are amortized as sales and marketing expense on a straight-line basis over the expected period of benefit, which considers future product upgrades for which a commission would be paid. These costs are periodically reviewed for impairment. Fair Value Measurements Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. When estimating fair value, the Company may use one or all the following approaches: • Market approach, which is based on market prices and other information from market transactions involving identical or comparable assets or liabilities. • Cost approach, which is based on the cost to acquire or construct comparable assets less an allowance for functional and/or economic obsolescence. • Income approach, which is based on the present value of the future stream of net cash flows. To measure fair value of assets and liabilities, the Company uses the following fair value hierarchy based on three levels of inputs: Level 1 — observable inputs, such as quoted prices in active markets for identical assets or liabilities; Level 2 — significant other observable inputs that are observable either directly or indirectly; Level 3 — significant unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions. Certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other liabilities are carried at cost, which approximates their fair value because of their short-term maturity. See Notes 5 and 12 for financial assets and liabilities held at carrying amount on the consolidated balance sheet and Note 6 for investments measured at fair value on a recurring basis. Property, Plant and Equipment Property, plant and equipment is stated at cost less accumulated depreciation. Major improvements are capitalized, while routine repairs and maintenance are expensed as incurred. Depreciation for property, plant and equipment, other than land and construction in progress, is based upon the following estimated useful lives using the straight-line method: Building and building improvements 20 to 39 years Leasehold improvements Lesser of lease term or useful life of asset Machinery and equipment 2 to 15 years Furniture and fixtures 3 to 5 years The Company assesses the recoverability of assets whenever events or changes in circumstances suggest that the carrying value of an asset may not be recoverable. The Company recognizes an impairment loss if the carrying amount of a long-lived asset is not recoverable based on its undiscounted future cash flows. The impairment loss is measured as the difference between the carrying amount and the fair value of the asset. Business Combinations The Company recognizes the assets and liabilities assumed in business combinations based on their estimated fair values at the date of acquisition. The Company allocates the purchase price in excess of net tangible assets acquired to identifiable intangible assets. The Company assesses the fair value of assets, including intangible assets, using a variety of methods and each asset is measured at fair value from the perspective of a market participant. Assets recorded from the perspective of a market participant that are determined to not have economic use for the Company are expensed immediately. Any excess purchase price over the fair value of the net tangible and intangible assets acquired is allocated to goodwill. Transaction costs and restructuring costs associated with a business combination are expensed as incurred. Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price of an acquired entity over the amounts assigned to assets and liabilities assumed in a business combination. The Company performs an assessment of its goodwill for impairment annually on October 1 or whenever events or changes in circumstances indicate there might be impairment. Goodwill is evaluated for impairment at the reporting unit level. The Company may assess its goodwill for impairment initially using a qualitative approach to determine whether conditions exist that indicate it is more likely than not that the fair value of a reporting unit is less than its carrying value. If management concludes, based on its assessment of relevant events, facts and circumstances that it is more likely than not that a reporting unit’s carrying value is greater than its fair value, then a quantitative analysis will be performed to determine if there is any impairment. Alternatively, the Company may elect to initially perform a quantitative analysis instead of starting with a qualitative analysis. In performing the quantitative test, the Company utilizes a two-step approach. The first step compares the carrying value of the reporting unit to its fair value. If the reporting unit’s carrying value exceeds its fair value, the Company would perform the second step and record an impairment loss to the extent that the carrying value of the reporting unit’s goodwill exceeds its implied fair value. Intangible assets acquired in a business combination are recorded at fair value, while intangible assets acquired in other transactions are recorded at cost and are stated at cost less accumulated amortization. Intangible assets with finite useful lives are amortized based on the pattern in which the economic benefits of the assets are estimated to be consumed over the following estimated useful lives of the assets: Customer relationships 14 years Internal-use software 3 to 5 years Intellectual property 15 years Amortization expense is included in selling, general and administrative expenses in the consolidated statement of income. The Company reviews intangible assets for impairment by comparing the fair value of the assets, estimated using an income approach, with their carrying value. If the carrying value exceeds the fair value of the intangible asset, the Company recognizes an impairment equal to the difference between the carrying value of the asset and the present value of future cash flows. The Company assesses the remaining useful life and the recoverability of intangible assets whenever events or circumstances indicate that the carrying value of an asset may not be recoverable using undiscounted cash flows. Cloud Computing Arrangements The Company capitalizes costs incurred to implement cloud computing arrangements that are service contracts within other current and non-current assets and amortizes such costs over the expected term of the hosting arrangement to the same income statement line as the associated cloud operating expenses. As of December 31, 2020 and 2019, the Company had net capitalized implementation costs of $24.2 million and $3.5 million, respectively. Amortization expense recorded during the period ended December 31, 2020 was $1.4 million and was insignificant for the period ended December 31, 2019. Leases The Company determines if an arrangement includes a lease at inception. Lease agreements generally have lease and non-lease components, which are accounted for separately. At lease commencement, the Company recognizes operating lease liabilities equal to the present value of the lease payments and operating lease assets representing the right to use the underlying asset for the lease term. The Company assesses if it is reasonably certain to exercise lease options to extend or terminate the lease for inclusion or exclusion in the lease term when the Company measures the lease liability. As the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at lease commencement in determining the present value of lease payments. The Company’s incremental borrowing rate estimates a secured rate that reflects the term of the lease, the nature of the underlying asset and the economic environment. The Company excludes leases with an expected term of one year or less from recognition on the consolidated balance sheet. Operating lease assets includes lease payments made prior to lease commencement and excludes lease incentives and initial direct costs incurred. Lease expense is recognized on a straight-line basis over the lease term. Contingencies The Company records a liability on the consolidated balance sheet for loss contingencies when a loss is considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. Product Warranty The Company provides a four-year warranty on its PDMs sold in the United States and Europe and a five-year warranty on PDMs sold in Canada and may replace Pods that do not function in accordance with product specifications. The Company estimates its warranty obligation at the time the product is shipped based on historical experience and the estimated cost to service the claims. Warranty expense is recorded in cost of revenue in the consolidated statements of income. Costs to service the claims reflect the current product cost. Since the Company continues to introduce new products and versions, the anticipated performance of the product over the warranty period is also considered in estimating warranty reserves. Revenue Recognition Effective January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers, and its related amendments (collectively referred to as ASC 606) using the modified retrospective method for all contracts not completed as of the date of adoption. The cumulate effect of applying the new revenue standard resulted in a $20.4 million decrease to the opening balance of accumulated deficit upon adoption, primarily related to how revenue is recognized for the Company’s drug delivery product line and the capitalization of contract acquisition costs such as commissions. Revenue is recognized when a customer obtains control of the promised products. The amount of revenue recognized reflects the consideration the Company expects to be entitled to receive in exchange for these products. To achieve this core principle, the Company applies the following five steps: • Identify Contracts with Customers. The Company’s contracts with its direct customers generally consist of a physician order form, a customer information form and, if applicable, third-party insurance (payor) approval. Contracts with the Company’s intermediaries are generally in the form of master service agreements against which firm purchase orders are issued. At the outset of the contract, the Company assesses the customer’s ability and intention to pay, which is based on a variety of factors including historical payment experience or, in the case of a new intermediary, published credit, credit references and other available financial information pertaining to the customer and, in the case of a new direct customer, an investigation of insurance eligibility. • Identify Performance Obligations. The performance obligations in contracts for the delivery of the Omnipod to new end-users, either directly to end-users or through intermediaries, primarily consist of the PDM and the initial and subsequent quantity of Pods ordered. In the Company’s judgment, these performance obligations are capable of being distinct and distinct in the context of the contract in that the customer can benefit from each item in conjunction with other readily available resources and the transfer of the PDM and the Pods is separately identifiable in the contract with the customer. • Determine Transaction Price. The price charged for the PDM and Pods is dependent on the Company’s pricing as established with third party payors and intermediaries. The Company provides a right of return for sales of its Omnipod to end-users and certain of our distributors and wholesalers. The Company also provides for certain rebates and discounts for sales of its product through intermediaries. These rights of return, discounts and rebates represent variable consideration and reduce the transaction price at the outset of the contract based on the Company’s estimates, which are primarily based on the expected value method using historical and other data (such as product return trends or forecast sale volumes) related to actual product returns, discounts and rebates paid in each market in which the Omnipod is sold. Variable consideration is included in the transaction price if it is probable that a significant future reversal of cumulative revenue under the contract will not occur; otherwise, the Company reduces the variable consideration. The variable consideration in the Company’s contracts is not typically constrained and the Company’s contracts do not contain significant financing components. • Allocate Transaction Price to Performance Obligations. The Company allocates the transaction price to each performance obligation based on its relative stand-alone selling price, which is determined based on the price at which the Company typically sells the deliverable or, if the performance obligation is not typically sold separately, the stand-alone selling price is estimated based on cost plus a reasonable profit margin or the price that a third party would charge for a similar product or service. • Recognize Revenue as Performance Obligations are Satisfied. The Company transfers the Omnipod at a point in time, which is determined based on when the customer gains control of the product. Generally, intermediaries in the U.S. obtain control upon shipment based on the contractual terms including right to payment and transfer of title and risk of ownership. For sales directly to end-users and international intermediaries, control is generally transferred at the time of delivery based on customary business practices related to risk of ownership, including transfer of title. The Company’s drug delivery product line includes sales of a modified version of the Omnipod to pharmaceutical and biotechnology companies who use the Company’s technology as a delivery method for their drugs. For the majority of this product line, revenue is recognized as the product is produced pursuant to the customer’s firm purchase commitments as the Company has an enforceable right to payment for performance completed to date and the inventory has no alternative use to the Company. Judgment is required in the assessment of progress toward completion of in-process inventory. The Company recognizes revenue over time using a blend of costs incurred to date relative to total estimated costs at completion and time incurred to date relative to total production time to measure progress toward the satisfaction of its performance obligations. The Company believes that both incurred cost and elapsed time reflect the value generated, which best depicts the transfer of control to the customer. Contract costs include third party costs as well as an allocation of manufacturing overhead. Shipping and Handling Costs The Company does not typically charge its customers for shipping and handling costs associated with shipping its product to its customers unless non-standard shipping and handling services are requested. These shipping and handling costs are included in selling, general and administrative expenses and were $10.1 million, $9.7 million and $6.6 million for the years ended December 31, 2020, 2019 and 2018, respectively. Advertising Costs The Company expenses advertising costs as they are incurred. Advertising expenses were $30.0 million, $11.2 million and $10.5 million for the years ended December 31, 2020, 2019 and 2018, respectively. Stock-Based Compensation The Company measures stock-based compensation on the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is generally the vesting period. The amount of stock-based compensation recognized during a period is based on the portion of the awards that are expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Income Taxes The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates that will be in effect in the years in which the differences are expected to reverse. The Company reviews its deferred tax assets for recoverability considering historical profitability, projected future taxable income, and the expected timing of the reversals of existing temporary differences and tax planning strategies. A valuation allowance is provided to reduce the deferred tax assets if, based on the available evidence, it is more likely than not that some or all the deferred tax assets will not be realized. The effect of a change in enacted tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Concentration of Credit Risk Financial instruments that subject the Company to credit risk primarily consist of cash and cash equivalents, short-term and long-term investments in marketable securities and accounts receivable. The Company maintains most of its cash, and short-term and long-term investments with a limited number of financial institutions that have a high investment grade credit rating. In addition to manufacturing the Omnipod System, the Company also purchases Omnipod Systems from two contract manufacturers. As of December 31, 2020, neither of these vendors represented 10% or more of the combined balance of accounts payable and accrued expenses and other current liabilities. As of December 31, 2019, one of these vendors represented 10% of the combined balance of accounts payable and accrued expenses and other current liabilities. See Note 4 for customer concentration. Recently Adopted Accounting Standards Effective January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 requires financial assets measured at amortized cost, such as the Company’s trade receivables and contract assets, to be presented net of expected credit losses, which may be estimated based on relevant information such as historical experience, current conditions and future expectation for each pool of similar financial assets. The new guidance also requires enhanced disclosures related to trade receivables and associated credit losses. The Company adopted ASU 2016-13 using the modified retrospective method, whereby the guidance is applied prospectively as of the date of adoption and prior periods are not restated. The cumulative effect of adopting ASU 2016-13 resulted in a $1.1 million increase to the opening balance of accumulated deficit upon adoption related to an increase in the allowance for credit losses on accounts receivable. The following table presents the activity in the allowance for credit losses, which is comprised primarily of our direct consumer receivable portfolio. The allowance for credit losses of other portfolios is insignificant. Year Ended (in millions) December 31, 2020 Credit losses at the beginning of the year $ 3.8 Effect of adoption 1.1 Credit losses at the beginning of the year, after adoption 4.9 Provision for expected credit losses 3.3 Write-offs charged against allowance (5.8) Recoveries of amounts previously written-off 0.5 Credit losses at the end of the year $ 2.9 Effective January 1, 2020, the Company adopted ASU 2017-04, Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). ASU 2017-04 requires an entity to measure the impairment of goodwill assigned to a reporting unit as the amount by which the carrying value of the assets and liabilities of the reporting unit, including goodwill, exceeds the reporting units’ fair value. The adoption of this guidance had no impact on the consolidated financial statements. |
