Significant Accounting Policies | Significant Accounting Policies Revenue Recognition . Revenue is recognized when a customer obtains control and receives the benefit of the promised goods or services (the performance obligation) in an amount that reflects the consideration we expect to receive in exchange for those goods or services (the transaction price). We measure revenue by estimating the transaction price based on the consideration specified in the client arrangement. Revenue is recognized as the performance obligations are satisfied. Our revenue is primarily derived from the planning and execution of advertising communications and marketing services in the following fundamental disciplines: Advertising & Media, Precision Marketing, Commerce & Branding, Experiential, Execution & Support, Public Relations and Healthcare. Our client contracts are primarily fees for service on a rate per hour or per project basis. Revenue is recorded net of sales, use and value added taxes. Performance Obligations. In substantially all our disciplines, the performance obligation is to provide advisory and consulting services at an agreed-upon level of effort to accomplish the specified engagement. Our client contracts are comprised of diverse arrangements involving fees based on any one or a combination of the following: an agreed fee or rate per hour for the level of effort expended by our employees; commissions based on the client’s spending for media purchased from third parties; qualitative or quantitative incentive provisions specified in the contract; and reimbursement for third-party costs that we are required to include in revenue when we control the vendor services related to these costs and we act as principal. The transaction price of a contract is allocated to each distinct performance obligation based on its relative stand-alone selling price and is recognized as revenue when, or as, the customer receives the benefit of the performance obligation. Clients typically receive and consume the benefit of our services as they are performed. Substantially all our client contracts provide that we are compensated for services performed to date and allow for cancellation by either party on short notice, typically 90 days, without penalty. Generally, our short-term contracts, which normally take 30 to 90 days to complete, are performed by a single agency and consist of a single performance obligation. As a result, we do not consider the underlying services as separate or distinct performance obligations because our services are highly interrelated, occur in close proximity, and the integration of the various components of a marketing message is essential to overall service. In certain of our long-term client contracts, which have a term of up to one year, the performance obligation is a stand-ready obligation, because we provide a constant level of similar services over the term of the contract. In other long-term contracts, when our services are not a stand-ready obligation, we consider our services distinct performance obligations and allocate the transaction price to each separate performance obligation based on its stand-alone selling price, including contracts for strategic media planning and buying services, which are considered to be multiple performance obligations, and we allocate the transaction price to each distinct service based on the staffing plan and the stand-alone selling price. In substantially all of our creative services contracts, we have distinct performance obligations for our services, including certain creative services contracts where we act as an agent and arrange, at the client’s direction, for third parties to perform studio production efforts. Revenue Recognition Methods. A substantial portion of our revenue is recognized over time, as the services are performed, because the client receives and consumes the benefit of our performance throughout the contract period, or we create an asset with no alternative use and are contractually entitled to payment for our performance to date in the event the client terminates the contract for convenience. For these client contracts, other than when we have a stand-ready obligation to perform services, revenue is recognized over time using input measures that correspond to the level of staff effort expended to satisfy the performance obligation on a rate per hour or equivalent basis. For client contracts when we have a stand-ready obligation to perform services on an ongoing basis over the life of the contract, typically for periods up to one year, where the scope of these arrangements is broad and there are no significant gaps in performing the services, we recognize revenue using a time-based measure resulting in a straight-line revenue recognition. From time to time, there may be changes in the client service requirements during the term of a contract and the changes could be significant. These changes are typically negotiated as new contracts covering the additional requirements and the associated costs, as well as additional fees for the incremental work to be performed. To a lesser extent, for certain other contracts where our performance obligations are satisfied in phases, we recognize revenue over time using certain output measures based on the measurement of the value transferred to the customer, including milestones achieved. Where the transaction price or a portion of the transaction price is derived from commissions based on a percentage of purchased media from third parties, the performance obligation is not satisfied until the media is run and we have an enforceable contract providing a right to payment. Accordingly, revenue for commissions is recognized at a point in time, typically when the media is run, including when it is not subject to cancellation by the client or media vendor. Principal vs. Agent. In substantially all our businesses, we incur third-party costs on behalf of clients, including direct costs and incidental, or out-of-pocket costs. Third-party direct costs incurred in connection with the creation and delivery of advertising or marketing communication services include, among others: purchased media, studio production services, specialized talent, including artists and other freelance labor, event marketing supplies, materials and services, promotional items, market research and third-party data and other related expenditures. Out-of-pocket costs include, among others: transportation, hotel, meals, shipping and telecommunication charges incurred by us in the course of providing our services. Billings related to out-of-pocket costs are included in revenue since we control the goods or services prior to delivery to the client. However, the inclusion of billings related to third-party direct costs in revenue depends on whether we act as a principal or as an agent in the client arrangement. In most of our businesses, including advertising, which also includes studio production efforts and media planning and buying services, public relations, healthcare advertising, precision marketing, commerce and branding businesses, we act as an agent and arrange, at the client’s direction, for third parties to perform certain services. In these cases, we do not control the goods or services prior to the transfer to the client. As a result, revenue is recorded net of these costs, equal to the amount retained for our fee or commission. In certain businesses we may act as principal when contracting for third-party services on behalf of our clients. In our experiential business and most of our execution and support businesses, including field marketing and certain specialty marketing businesses, we act as principal because we control the specified goods or services before they are transferred to the client and we are responsible for providing the specified goods or services, or we are responsible for directing and integrating third-party vendors to fulfill our performance obligation at the agreed upon contractual price. In such arrangements, we also take pricing risk under the terms of the client contract. In certain specialty media buying businesses, we act as principal when we control the buying process for the purchase of the media and contract directly with the media vendor. In these arrangements, we assume the pricing risk under the terms of the client contract. When we act as principal, we include billable amounts related to third-party costs in the transaction price and record revenue over time at the gross amount billed, including out-of-pocket costs, consistent with the manner that we recognize revenue for the underlying services contract. However, in media buying contracts where we act as principal, we recognize revenue at a point in time, typically when the media is run, including when it is not subject to cancellation by the client or media vendor. Variable Consideration. Some of our client arrangements include variable consideration provisions, which include performance incentives, tiered commission structures and vendor rebates in certain markets outside of the United States. Variable consideration is estimated and included in total consideration at contract inception based on either the expected value method or the most likely outcome method. These estimates are based on historical award experience, anticipated performance and other factors known at the time. Performance incentives are typically recognized in revenue over time. Variable consideration for our media businesses in certain international markets includes rebate revenue and is recognized when it is probable that the media will be run, including when it is not subject to cancellation by the client. In addition, when we receive rebates or credits from vendors for transactions entered into on behalf of clients, they are remitted to the clients in accordance with contractual requirements or retained by us based on the terms of the client contract or local law. Amounts passed on to clients are recorded as a liability and amounts retained by us are recorded as revenue when earned, typically when the media is run. Operating Expenses. Operating expenses include cost of services, selling, general and administrative expenses, or SG&A, and depreciation and amortization. We measure cost of services in two distinct categories: salary and service costs and occupancy and other costs. As a service business, salary and service costs make up a significant portion of our operating expenses, and substantially all these costs comprise the essential components directly linked to the delivery of our services. Salary and service costs include employee compensation and benefits, freelance labor, third-party service costs, and third-party incidental costs. Third-party service costs include vendor costs when we act as principal in providing services to our clients. Third-party incidental costs, primarily consist of client-related travel and incidental out-of-pocket costs, which we bill back to the client directly at our cost and which we are required to include in revenue. Occupancy and other costs consist of the indirect costs related to the delivery of our services, including office rent and other occupancy costs, equipment rent, technology costs, general office expenses and other expenses. SG&A expenses primarily consist of third-party marketing costs, professional fees and compensation and benefits and occupancy and other costs of our corporate and executive offices, which includes group-wide finance and accounting, treasury, legal and governance, human resource oversight and similar costs. Cash and Cash Equivalents. Cash and cash equivalents include cash in banks and highly liquid interest-bearing time deposits with original maturities of three months or less. Due to the short-term nature of these investments, carrying value approximates fair value. We have a policy governing counterparty credit risk for financial institutions that hold our cash and cash equivalents and we have deposit limits for each institution. Short-Term Investments. Short-term investments represent time deposits with original maturities ranging from 91 to 364 days. These investments are classified as held-to-maturity securities because we have the positive intent and ability to hold until maturity. Held-to-maturity securities are carried at amortized cost, which approximates fair value. Fair value is based on observable interest rates for similar securities. Work in Process. Work in process represents accrued costs incurred on behalf of customers, including media and production costs and fees, other third-party costs and contract assets that have not yet been billed. Media and production costs are billed during the production process in accordance with the terms of the client contract. Substantially all unbilled fees and costs will be billed within the next 30 days. Contract assets primarily include incentive fees, which are not material, and will be billed to clients in accordance with the terms of the client contract. Property and Equipment. Property and equipment are carried at cost and are depreciated over the estimated useful lives of the assets using the straight-line method ranging from: three five seven ten Equity Method Investments. Investments in companies where we exercise significant influence over the operating and financial policies of the investee and own less than 50% of the equity are accounted for using the equity method. Our proportionate share of the net income or loss of equity method investments is included in results of operations and any dividends received reduce the carrying value of the investment. The excess of the cost of our investment over our proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill and included in the carrying amount of the investment. Goodwill in the equity method investments is not amortized. Gains and losses from changes in our ownership interests are recorded in results of operations until control is achieved. In circumstances where a change in our ownership interest results in obtaining control, the existing carrying value of the investment is remeasured to the acquisition date fair value and any gain or loss is recognized in results of operations. We periodically review the carrying value of the equity method investments to determine if there has been an other-than-temporary decline in carrying value. A variety of factors are considered when determining if a decline in carrying value is other-than-temporary, including the financial condition and business prospects of the investee, as well as our investment intent. Marketable Equity Securities. Marketable equity securities are measured at fair value and changes in fair value are recognized in results of operations. Non-Marketable Equity Securities . Non-marketable equity securities do not have a readily determinable fair value and are measured at cost, less any impairment, and are adjusted for observable changes in fair value from transactions for identical or similar securities of the same issuer. Business Combinations. In a business combination, the assets acquired, including identified intangible assets, liabilities assumed and any noncontrolling interest in the acquired business are recorded at acquisition date fair value. In circumstances where control is obtained and less than 100% of a business is acquired, goodwill related to the noncontrolling shareholders is recorded as if 100% were acquired. Acquisition-related costs, including advisory, legal, accounting, valuation and other costs are expensed as incurred. Certain acquisitions include an initial payment at closing and provide for future additional contingent purchase price payments (earn-outs), which are recorded as a liability at the acquisition date fair value using the discount rate in effect on the acquisition date. Subsequent changes in the fair value of the liability are recorded in results of operations. Amounts earned under the contingent purchase price arrangements may be subject to a maximum and payment is not contingent upon future employment. The results of operations of acquired businesses are included in results of operations from the acquisition date. Goodwill and Intangible Assets. Goodwill represents the excess of the acquisition cost over the fair value of the net assets acquired. Goodwill is not amortized but is periodically reviewed for impairment. Intangible assets comprise customer relationships, including the related customer contracts and trade names, and purchased and internally developed software and are amortized over their estimated useful lives ranging from five twelve In 2023, to better align with our internal financial processes, the date of our annual impairment test was changed from June 30 to May 1. We will continue to evaluate goodwill for impairment at least annually on May 1 and whenever events or circumstances indicate the carrying value may not be recoverable. The impairment evaluation compares the fair value of each reporting unit, which we identified as our six agency networks, to its carrying value, including goodwill. If the fair value of the reporting unit is equal to or greater than its carrying value, goodwill is not impaired. Goodwill is impaired when the carrying value of the reporting unit exceeds its fair value. Goodwill is written down to its fair value through a non-cash expense recorded in results of operations in the period the impairment is identified. We identified our regional reporting units as components of our operating segments, which are our six global agency networks. The regional reporting units and practice areas monitor the performance and are responsible for the agencies in their region. The regional reporting units report to the segment managers and facilitate the administrative and logistical requirements of our key client matrix organization structure for delivering services to clients in their regions. We have concluded that, for each of our operating segments, their regional reporting units have similar economic characteristics and should be aggregated for purposes of testing goodwill for impairment at the operating segment level. Our conclusion was based on a detailed analysis of the aggregation criteria set forth in FASB ASC Topic 280, Segment Reporting , and in FASB ASC Topic 350. Consistent with our fundamental business strategy, the agencies within our regional reporting units serve similar clients in similar industries, and in many cases the same clients. In addition, the agencies within our regional reporting units have similar economic characteristics, and the employees share similar skill sets. The main economic components of each agency are employee compensation and related costs, and direct service costs and occupancy and other costs, which include rent and occupancy costs, technology costs that are generally limited to personal computers, servers and off-the-shelf software and other overhead expenses. Finally, the expected benefits of our acquisitions are typically shared by multiple agencies in various regions as they work together to integrate the acquired agency into our virtual client network strategy. We use the following valuation methodologies to determine the fair value of our reporting units: (1) the income approach, which utilizes discounted expected future cash flows, (2) comparative market participant multiples of EBITDA (earnings before interest, taxes, depreciation and amortization) and (3) when available, consideration of recent and similar acquisition transactions. The market assumptions used in our assessment reflected the current economic environment (see Note 1 - Risks and Uncertainties ). Based on the results of the annual impairment test, we concluded that at May 1, 2023 and June 30, 2022, goodwill was not impaired because either the fair value of each reporting unit was substantially in excess of its respective net book value, or for reporting units with a negative book value, fair value of assets exceeds total assets. Subsequent to the annual goodwill impairment test, there have been no events or circumstances that triggered the need for an interim impairment test. Debt Issuance Costs. Debt issuance costs are capitalized and amortized in interest expense over the life of the related debt and are presented as a reduction to the carrying amount of debt. Temporary Equity - Redeemable Noncontrolling Interests. Owners of noncontrolling equity interests in some of our subsidiaries have the right in certain circumstances to require us to purchase all or a portion of their equity interests at fair value as defined in the applicable agreements. The intent of the parties is to approximate fair value at the time of redemption by using a multiple of earnings that is consistent with generally accepted valuation practices used by market participants in our industry. These contingent redemption rights are embedded in the equity security at issuance, are not free-standing instruments, do not represent a de facto financing and are not under our control. Treasury Stock. Repurchases of our common stock are accounted for at cost and are recorded as treasury stock. The excise tax on net stock repurchases is recorded as a cost of acquiring treasury stock. Reissued treasury stock, primarily in connection with share-based compensation plans, is accounted for at average cost. Gains or losses on reissued treasury stock arising from the difference between the average cost and the fair value of the award are recorded in additional paid-in capital and do not affect results of operations. Noncontrolling Interests. Noncontrolling interests represent equity interests in certain subsidiaries held by third parties. Noncontrolling interests are presented as a component of equity and the proportionate share of net income attributed to the noncontrolling interests is recorded in results of operations. Changes in noncontrolling interests that do not result in a loss of control are accounted for in equity. Gains and losses resulting from a loss of control are recorded in results of operations. Foreign Currency Translation and Transactions. Substantially all of our foreign subsidiaries use their local currency as their functional currency. Assets and liabilities are translated from the local functional currency into U.S. Dollars at the exchange rate on the balance sheet date and revenue and expenses are translated at the average exchange rate for the period. Translation adjustments are recorded in accumulated other comprehensive income. Foreign currency gains and losses arising from transactions not in the subsidiaries’ local currency are recorded in results of operations. We recorded foreign currency transaction losses of $14.0 million and $3.3 million in 2023 and 2021, respectively, and recorded foreign currency transaction gains of $1.1 million in 2022. Foreign currency gains and losses for hyper-inflationary economies are recorded in results of operations. Share-Based Compensation. Share-based compensation for restricted stock and stock option awards is measured at the grant date fair value. The fair value of restricted stock awards is determined and fixed using the closing price of our common stock on the grant date and is recorded in additional paid-in capital. The fair value of stock option awards is determined using the Black-Scholes option valuation model. For awards with a service only vesting condition, compensation expense is recognized on a straight-line basis over the requisite service period. For awards with a performance vesting condition, compensation expense is recognized on a graded-vesting basis. Typically, all share-based awards are settled with treasury stock. See Note 10 for additional information regarding our specific award plans. Salary Continuation Agreements. Arrangements with certain present and former employees provide for continuing payments for periods up to ten years after cessation of full-time employment in consideration for agreement by the employees not to compete with us and to render consulting services during the postemployment period. Such payments, which are subject to certain limitations, including our operating performance during the postemployment period, represent the fair value of the services rendered and are expensed in such periods. Severance. The liability for one-time termination benefits, such as severance pay or benefit payouts, is measured and recognized at fair value in the period the liability is incurred. Subsequent changes to the liability are recognized in results of operations in the period of change. Defined Benefit Pension Plans and Postemployment Arrangements . The funded status of our defined benefit plans is recorded as an asset or liability. Funded status is the difference between the fair value of plan assets and the benefit obligation at December 31, the measurement date, determined on a plan-by-plan basis. The benefit obligation for the defined benefit plans is the projected benefit obligation, or PBO, which represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. The fair value of plan assets represents the current market value. Overfunded plans, where the fair value of plan assets exceeds the benefit obligation, are aggregated and recorded as a prepaid pension asset equal to the excess. Underfunded plans, where the benefit obligation exceeds the fair value of plan assets, are aggregated and recorded as a liability equal to the excess. The benefit obligation liability for our postemployment arrangements is the PBO and these arrangements are not funded. The current portion of the benefit obligation for the defined benefit plans and postemployment arrangements, which represents the actuarial present value of benefits payable in the next twelve months that exceed the fair value of plan assets, is recorded in other current liabilities and the long-term portion is recorded in long-term liabilities. Deferred Compensation . Some of our subsidiaries have deferred compensation arrangements with certain executives that provide for payments over varying terms upon retirement, cessation of employment or death. The cost of these arrangements is accrued during the employee’s service period. Income Taxes. We use the asset and liability method of accounting for income taxes. Under this method, income tax expense is recognized for the amount of taxes payable for the current period and the deferred taxes recognized during the period. Deferred income taxes reflect the temporary difference between assets and liabilities that are recognized for financial reporting purposes and income tax purposes and are recorded as noncurrent. Deferred income taxes are measured using the enacted tax rates that are assumed to be in effect when the differences reverse. Valuation allowances are recorded where it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, we evaluate factors such as prior earnings history, expected future earnings, carry-back and carry-forward periods and tax strategies that could potentially enhance the likelihood of the realization of a deferred tax asset. Interest and penalties related to tax positions taken in our tax returns are recorded in income tax expense. We record a liability for uncertain tax positions that reflects the treatment of certain tax positions taken in our tax returns that do not meet the more-likely-than not threshold, or that meet the more-likely-than-not threshold but have measurement related unrecognized tax benefits. Until these positions are sustained by the taxing authorities or the statute of limitations concerning such issues lapses, we do not generally recognize the tax benefits resulting from such positions. Net Income Per Share. Basic net income per share is based on the weighted average number of common shares outstanding during the period. Diluted net income per share is based on the weighted average number of common shares outstanding, plus the dilutive effect of common share equivalents, which include outstanding stock options and restricted stock awards. Leases. At the inception of a contract, we assess whether the contract is, or contains, a lease. A lease is classified as a finance lease if any one of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not meet any one of the criteria. Substantially all our operating leases are office space leases, and substantially all our finance leases are office furniture and technology equipment leases. For all leases a right-of-use, or ROU, asset and lease liability are recognized at the lease commencement date. The lease liability represents the present value of the lease payments under the lease. The ROU asset is initially measured at cost, which includes the initial lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All ROU assets are reviewed for impairment. The lease liability is initially measured as the present value of the lease payments, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, our secured incremental borrowing rate for the same term as the underlying lease. For real estate and certain equipment operating leases, we use our secured incremental borrowing rate. For finance leases, we use the rate implicit in the lease or our secured incremental borrowing rate if the implicit lease rate cannot be determined. Lease payments included in the measurement of the lease liability comprise: the fixed noncancelable lease payments, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early. Lease components, including fixed payments for real estate taxes and insurance for office space leases, are included in the measurement of the initial lease liability. Office space leases may contain variable lease payments, which include payments based on an index or rate. Variable lease payments based on an index or rate are initially measured using the index or rate in effect at lease commencement. Additional payments based on the change in an index or rate, or payments based on a change in our portion of the operating expenses, including real estate taxes and insurance, are recorded as a period expense when incurred. Lease modifications result in remeasurement of the lease liability. Operating lease expense is recognized on a straight-line basis over the lease term. Lease expense may include variable lease payments incurred in the period that were not included in the initial lease liability. Finance lease expense consists of the amortization of the ROU asset on a straight-line basis over the lease term and interest expense determined on an amortized cost basis. Finance lease payments are allocated between a reduction of the lease liability and interest expense. Concentration of Credit Risk. We provide advertising, marketing and corporate communications services to several thousand clients that operate in nearly every industry sector of the global economy, and we grant credit to qualified clients in the normal course of business. Due to the diversified nature of our client base, we do not believe that we are exposed to a concentration of credit risk as our largest client accounted for 3.0% of revenue in 2023. Derivative Financial Instruments. All derivative instruments, including certain derivative instruments embedded in other contracts, are recorded at fair value. Derivatives qualify for hedge accounting if: the hedging instrument is designated as a hedge, the hedged exposure is specifically identifiable and exposes us to risk, and a change in fair value of the derivative financial instrument and an opposite change in the fair value of the hedged exposure have a high degree of correlation. The method of assessing hedge effectiveness and measuring hedge ineffectiveness is formally documented. Hedge effectiveness is assessed, and hedge ineffectiveness is measured at least quarterly throughout the designat |
