Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Cash and Cash Equivalents and Marketable Securities Cash and cash equivalents are stated at fair value. The Company considers all highly liquid investments purchased with original maturities of three months or less at the time of purchase to be cash equivalents. Marketable securities, primarily consisting of U.S. Government and agency securities with original maturities greater than three months but less than one year when purchased, are classified as available-for-sale, and are stated at fair value. Unrealized gains and losses on marketable securities are excluded from earnings and reported as a component of other comprehensive income (loss). Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to clients in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company applies the following five-step model to recognize revenue from contracts with clients: • Identification of the contract, or contracts, with a client • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, a performance obligation is satisfied Progyny’s contracts typically have a stated term of three years and include contractual termination options after the first year, allowing the client to terminate the contract with 30 to 90 days’ notice. Fertility Benefits Solution Revenue Progyny primarily generates revenue through its fertility benefits solution, in which Progyny provides self-insured enterprise entities (‘‘clients’’) and their employees and partners (together, ‘‘members’’) with fertility benefits. As part of the fertility benefits solution, Progyny provides access to effective and cost-efficient fertility treatments, referred to as Smart Cycles, as well as other related services. Smart Cycles are proprietary treatment bundles that include certain medical services available to members through Progyny’s proprietary, credentialed network of provider clinics. In addition to access to Progyny’s Smart Cycle treatment bundles and access to Progyny’s network of provider clinics, the fertility benefits solution includes other comprehensive services, which Progyny refers to as care management services, such as active management of the provider clinic network, real-time member eligibility and treatment authorization, member-facing digital tools throughout the Smart Cycle and detailed quarterly reporting all supported by client facing account management and end-to-end comprehensive member support provided by Progyny’s in house staff of PCAs. The promises within Progyny’s fertility benefits contract with a client represent a single performance obligation because Progyny provides a significant service of integrating the Progyny designed Smart Cycles and access to the fertility treatment services provided by provider clinics with the other comprehensive services into the combined fertility benefits solution that the client contracted to receive. Progyny’s fertility benefits solution is a stand-ready obligation that is satisfied over the contract term. Progyny’s contracts include the following sources of consideration, which are all variable: a per employee per month (‘‘PEPM’’) administration fee (in most, but not all contracts) and a fixed rate per Smart Cycle. The PEPM administration fee is allocated between the fertility benefits solution and the pharmacy benefits solution based on standalone selling price, estimated using an expected cost-plus margin method. The Company allocates the variable consideration related to the fixed rate per Smart Cycle to the distinct period during which the related services were performed as those fees relate specifically to the Company’s efforts to provide its fertility benefits solution to its clients in the period and represents the consideration the Company is entitled to for the fertility benefits services provided. As a result, the fixed rate per Smart Cycle is included in the transaction price and recognized in the period in which the Smart Cycle is provided to the member. Progyny’s contracts also include potential service level agreement refunds related to outcome-based service metrics. These service level refunds, which are determined based on results of a full plan year, if met, are based on a percentage of the PEPM fee paid by clients. The Company estimates the variable consideration related to the total PEPM administration fee, less estimated refunds related to service level agreements, and recognizes the amounts allocated to the fertility benefits solution ratably over the contract term. Progyny’s estimates of service level agreement refunds, have not historically resulted in significant adjustments to the transaction price. Clients are typically invoiced on a monthly basis for the PEPM administration fee. Progyny invoices its clients and members for their respective portions of the fixed rate per Smart Cycle bundle when all treatment services within a Smart Cycle are completed by the provider clinic. Once an invoice is issued, payment terms are typically between 30 to 60 days. The Company assesses whether it is the principal or the agent for each arrangement with a client, since fertility treatment services are provided by a third party—the provider clinics. The Company is the principal in its arrangements with clients and therefore presents revenue gross of the amounts paid to the provider clinics because Progyny controls the specified service (the fertility benefits solution) before it is transferred to the client. Progyny integrates the fertility treatment services provided by the provider clinics into the overall fertility benefits solution that the client contracted to receive. In addition, Progyny defines the scope of the potential services to be performed by the provider clinics and monitors the performance of the provider clinics. Furthermore, Progyny is primarily responsible for fulfilling the promise to the client and has discretion in setting the pricing, as Progyny separately negotiates agreements with the provider clinics, which establish pricing for each treatment service. Pricing of services from provider clinics is independent from the fees charged to clients. Pharmacy Benefits Solution Revenue For clients that have the fertility benefits solution, Progyny offers, as an add-on, its pharmacy benefits solution, which is a separate, fully integrated pharmacy benefit. As part of the pharmacy benefits solution, Progyny provides care management services, which include Progyny’s formulary plan design, prescription fulfillment, simplified authorization and timely delivery of the medications used during treatment through Progyny’s network of specialty pharmacies, and clinical services consisting of member assessments, UnPack It calls, telephone support, online education, medication administration training, pharmacy support services and continuing PCA support. The pharmacy-related promises represent a single performance obligation because Progyny provides a significant service of integrating the formulary plan design, prescription fulfillment, clinical services and PCA support into the combined pharmacy benefits solution that the client contracted to receive. The pharmacy benefits solution is a stand-ready obligation that is satisfied over the contract term. Progyny’s contracts include the following sources of consideration, all of which are variable: a PEPM administration fee (in most, but not all contracts) and a fixed fee per fertility drug. As described above, the PEPM administration fee, less estimated refunds related to service level agreements, is allocated to the pharmacy benefits solution and recognized ratably over the contract term. The Company allocates the variable consideration related to the fixed fee per fertility drug to the distinct period during which the related services were performed, as those fees relate specifically to the Company’s efforts to provide its pharmacy benefits solution to clients in the period and represents the consideration the Company is entitled to for the pharmacy benefits services provided. As a result, the fixed fee per fertility drug is included in the transaction price and recognized in the period in which the Company is entitled to consideration from a client, which is when a prescription is filled and delivered to the members. As stated above, clients are invoiced on a monthly basis for the PEPM administration fee. Progyny invoices the client and the member for their respective portions of the fixed fee per fertility drug, when the prescription services are completed by the specialty pharmacies. Once an invoice is issued, payment terms are typically between 30 to 60 days. The Company assesses whether it is the principal or the agent for each arrangement with a client, as prescription fulfillment and clinical services are provided by a third party—the specialty pharmacies. The Company is the principal in its arrangements with clients, and therefore presents revenue gross of the amounts paid to the specialty pharmacies. Progyny controls the specified service (the pharmacy benefits solution) before it is transferred to the client. Progyny integrates the prescription fulfillment and clinical services provided by the pharmacies and PCAs into the overall pharmacy benefits solution that the client contracted to receive. In addition, Progyny defines the scope of the potential services to be performed by the specialty pharmacies and monitors the performance of the specialty pharmacies. Furthermore, Progyny is primarily responsible for fulfilling the promise to the client and has discretion in setting the pricing, as Progyny separately negotiates agreements with pharmacies, which establish pricing for each drug. Pricing of fertility drugs is independent from the fees charged to clients. The Company does not disclose the transaction price allocated to remaining performance obligations because all of the transaction price is variable and is allocated to the distinct periods to which the services relate, as discussed above. The remaining contract term is typically less than one year, due to the client’s contractual termination options. There were no material contract asset or contract liability balances as of December 31, 2023 and 2022. Accrued Receivables and Accrued Claims Payable Accrued receivables are estimated based on historical experience for those fertility benefits services provided but for which a claim has not been received from the provider clinic at the end of the reporting period, which includes assumptions regarding the lag between authorization date and service date as well as estimates for changes and cancellations of services. At the same time, cost of services and accrued claims payables are estimated based on the amount to be paid to the provider clinic and expected gross margin on fertility benefits services. Estimates are adjusted to actual at the time of billing. Adjustments to original estimates have not been material. As of December 31, 2023 and 2022, accrued receivables were $45.8 million and $54.6 million, respectively. Accrued receivables are included within accounts receivable in the consolidated balance sheet. Accrued claims payable of $30.3 million and $31.1 million as of December 31, 2023 and 2022, respectively, are included within accrued expenses and other current liabilities in the consolidated balance sheet. Claims payable are generally paid within 30 days based on contractual terms. As of December 31, 2023 and December 31, 2022, unbilled receivables, which represent claims received and approved but unbilled at the end of the reporting period, were $45.1 million and $42.9 million, respectively. Unbilled receivables are typically billed to clients within 30 days of the approved claim based on the contractual billing schedule agreed upon with the client. Unbilled receivables are included in accounts receivable in the consolidated balance sheet. Accounts Receivable and Allowance for Doubtful Accounts The accounts receivable balance primarily includes amounts due from clients and members. The Company estimates the allowance for doubtful accounts based on the lifetime expected credit losses for the client and member receivable pools, respectively. Under this current expected credit losses model, the Company determines the allowance for doubtful accounts based on factors such as the age of the receivable balance, historical experience, current economic conditions, and reasonable and supportable forecasts of future economic conditions. An allowance for credit losses is applied at the time the asset is recognized. Expected credit losses are recorded as general and administrative expenses on the consolidated statements of operations. The following table provides a summary of the activity in this allowance (in thousands): Years Ended December 31, 2023, 2022 and 2021 December 31, 2023 Balance at Beginning of Period Charged to Costs and Expenses Write-offs Balance at End of Period Allowance for doubtful accounts $ 28,328 $ 19,934 $ (1,626) $ 46,636 December 31, 2022 Allowance for doubtful accounts $ 17,379 $ 13,794 $ (2,845) $ 28,328 December 31, 2021 Allowance for doubtful accounts $ 9,502 $ 9,783 $ (1,906) $ 17,379 Cost of Services Fertility Benefits Services Fertility benefits services costs include: (1) fees paid to provider clinics within the Company’s network, labs and anesthesiologists; (2) costs incurred (including salaries, bonuses, benefits, stock-based compensation expense, other related costs, and an allocation of the Company's general overhead, depreciation and amortization) for those employees associated with care management service functions: Provider Account Management, PCA, Provider Relations and Claims Processing teams; and (3) related information technology support costs. Contracts with provider clinics are typically for a term of one Pharmacy Benefits Services Pharmacy benefits services costs include: (1) the fees for prescription drugs dispensed and clinical services provided during the reporting period by specialty pharmacy partners; (2) costs incurred (including salaries, bonuses, benefits, stock-based compensation expense, other related costs, and an allocation of the Company's general overhead, depreciation and amortization) for those employees associated with care management service functions: PCA, Provider Relations and Claims Processing teams; and (3) related information technology support costs. Contracts with the specialty pharmacies are typically for a term of one year. In the specialty pharmacy contracts, the contractual fees of prescription drugs sold includes the cost of the prescription drugs purchased and shipped to members by the Company’s specialty mail service dispensing pharmacies, net of any volume-related or other discounts. Vendor Rebates The Company receives a rebate on formulations purchased and dispensed by the Company’s specialty pharmacies. The Company’s contractual arrangements with pharmacy program partners provide for the Company to receive a discount (or rebate) from established list prices paid subsequent to dispensing when products are purchased indirectly from a pharmacy program partner (such as through a specialty pharmacy). These rebates are recognized as a reduction of cost of services when prescriptions are dispensed and are generally estimated and billed to manufacturers within 20 days after the end of each month. The effect of adjustments resulting from the reconciliation of rebates recognized to the amounts billed and collected has not been material to the Company’s results of operations. Concentration of Credit Risk and Off-Balance-Sheet Risk Financial instruments that potentially subject the Company to concentrations of credit risk consists primarily of cash and cash equivalents, marketable securities, and accounts receivable. The Company invests its cash and cash equivalents and marketable securities with highly rated financial institutions and management believes that the financial risks associated with its cash equivalents are minimal. Substantially all of the Company’s cash is maintained with two financial institutions with high credit standings. From time to time, such deposits may exceed federally insured limits. The Company regularly reviews the outstanding accounts receivable balances and makes estimates of the lifetime expected credit losses based upon consideration of factors such as the age of the receivable balance, historical experience, current economic conditions, and reasonable and supportable forecasts of future economic conditions. In addition, the Company periodically evaluates the financial condition of its clients and other parties to manage credit risk related to accounts receivable. As of December 31, 2023 and 2022, one vendor accounted for 22% and 30%, respectively, of total receivables. Property and Equipment Property and equipment consist of computer equipment, machinery and equipment, furniture and fixtures, leasehold improvements, and capitalized software development costs. The assets are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method based on estimated useful lives and in the case of leasehold improvements, the shorter of the useful life or the remaining term of the lease (see Note 5). Goodwill and Intangible Assets Goodwill represents the excess of the consideration transferred over the fair value of the assets acquired and liabilities assumed in a business combination. Other intangible assets consist of trademarks, physician network, and the websites acquired in the Fertility Authority acquisition. Goodwill, including other definite-lived intangible assets, are carried at their initial acquisition date fair value less any impairment. Other intangible assets are recorded at fair value at the date of acquisition, less accumulated amortization. Amortization is calculated using the straight-line method based on estimated useful lives. Goodwill is reviewed for impairment annually as of October 1st of each year or when an interim triggering event has occurred indicating potential impairment. Events or changes in circumstances which could trigger an impairment review, which are assessed at the reporting unit level, include significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business, significant negative industry or economic trends, significant underperformance relative to historical or projected future results of operations, a significant adverse change in the business climate, an adverse action or assessment by a regulator, unanticipated competition or a loss of key personnel. The Company has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of the reporting unit is less than its carrying amount, then additional impairment testing is not required. However, if an entity concludes otherwise, then it is required to perform the first of a two-step impairment test. The first step involves comparing the estimated fair value of the reporting unit with its respective book value, including goodwill. If the estimated fair value exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. If the carrying amount of goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in an amount equal to the excess. The Company tests for goodwill impairment for each reporting unit, which is at the operating segment or one level below the operating segment. This analysis requires us to make a series of assumptions to (1) evaluate whether any impairment exists and (2) measure the amount of impairment. There was no impairment of goodwill or intangible assets for the years ended December 31, 2023, 2022, and 2021. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. In such instances, the recoverability of assets to be held and used is measured first by a comparison of the carrying amount of an asset group to future undiscounted net cash flows expected to be generated by the assets. If such assets are considered to be impaired, an impairment loss would be recognized if the carrying amount of the asset exceeds the fair value of the asset or asset group. The fair value is determined based on valuation techniques such as a comparison to fair values of similar assets or using a discounted cash flow analysis. There were no impairments recorded for the years ended December 31, 2023, 2022 and 2021. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use assets, accrued expenses and other current liabilities, and operating lease noncurrent liabilities on the consolidated balance sheets. The Company elects to account for each separate lease and non-lease component as a single lease component. As of December 31, 2023 and 2022, the Company has no financing lease arrangements. In accordance with ASC 842, the Company records a right-of-use asset (“ROU”) and lease liability in connection with its operating leases. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. To determine the present value of lease payments, the Company utilizes the rate implicit in the lease, if available. If the rate implicit in the lease is not readily determinable, the Company uses its secured incremental borrowing rate to determine the present value of the lease payments. The determination of the Company’s incremental borrowing rate requires judgment and is primarily based on publicly available information for companies within the same industry and with similar credit profiles. The rate is then adjusted for the lease term and other specific terms included in the Company’s lease arrangements. The incremental borrowing rate is subsequently reassessed upon a modification to the lease arrangement. The operating lease ROU asset also includes any lease payments made prior to commencement date and excludes lease incentives and initial direct costs incurred. ROU assets are subsequently assessed for impairment in accordance with the Company’s accounting policy for long-lived assets. Stock-Based Compensation The Company accounts for stock-based compensation awards in accordance with FASB ASC Topic 718, Compensation—Stock Compensation (ASC 718). ASC 718 requires all stock-based payments, including restricted stock units and grants of stock options, to be recognized in the consolidated statements of operations based on their respective fair values. The fair value of the Company’s restricted stock units has been determined utilizing the closing market price of the Company’s common stock on the date of the grant, including those with performance-based vesting criteria. The fair value of the Company’s stock options and stock purchased under the employee stock purchase plan has been determined using the Black-Scholes option-pricing model, which requires the input of subjective assumptions, including (i) the expected stock price volatility, (ii) the expected term of the award, (iii) the risk-free interest rate and (iv) expected dividends. Due to the lack of historical and implied volatility data of the Company’s common stock, the expected stock price volatility has been estimated based on the historical volatilities of the daily closing prices of a specified group of companies in Progyny’s industry for a period equal to the expected term of the option. Progyny selected companies with comparable characteristics to the Company, including enterprise value, risk profiles and position within the industry, that have historical stock price information sufficient to meet the expected term of the stock options. The expected term of the options granted represents the period of time that options granted are expected to be outstanding and is calculated using the simplified method, which is the mid-point between the vesting date and the end of the contractual term for each option. For non-employee service-based awards, the expected term is estimated based on the remaining contractual term of such awards. The risk-free interest rate is based on the yield of zero-coupon, U.S. Treasury securities for the period that is consistent with the expected term of the stock option. The Company has not paid, and does not anticipate paying, cash dividends on its shares of common stock; therefore, the expected dividend yield is zero. The Company’s stock-based awards are subject to service-based or performance-based vesting conditions. The Company recognizes compensation expense for service-based awards over the vesting period of the award on a straight-line basis. Compensation expense related to awards with performance-based vesting conditions is recognized over the requisite service period when achievement of the performance condition is considered probable. Income Taxes The Company accounts for income taxes in accordance with FASB ASC Topic 740, Income Taxes (“ASC 740”), including updates in ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which the Company adopted as of January 1, 2021. Deferred income taxes are recorded for the expected tax consequences of temporary differences between the tax basis of assets and liabilities for financial reporting purposes and amounts recognized for income tax purposes. The Company periodically reviews the recoverability of deferred tax assets recorded on the consolidated balance sheet and provides valuation allowances as deemed necessary to reduce such deferred tax assets to the amount that will, more likely than not, be realized. Income tax expense consists of taxes currently payable and changes in deferred tax assets and liabilities calculated according to local tax rules. Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considers all available evidence for each jurisdiction including past operating results, estimates of future taxable income and the feasibility of ongoing tax planning strategies. In the event the Company changes its determination as to the amount of deferred tax assets that can be realized, the Company will adjust its valuation allowance with a corresponding impact to income tax expense in the period in which such determination is made. The amount of deferred tax provided is calculated using tax rates enacted at the balance sheet date. The impact of tax law changes is recognized in periods when the change is enacted. A two-step approach is applied pursuant to ASC 740 in the recognition and measurement of uncertain tax positions taken or expected to be taken in a tax return. The first step is to determine if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained in an audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company’s policy is to recognize interest and penalty expenses associated with uncertain tax positions as a component of income tax expense in the consolidated statements of operations and comprehensive income. As of December 31, 2023, 2022 and 2021, the Company had no significant accrued interest or penalties related to uncertain tax positions and no amounts have been recognized in the Company’s consolidated statements of operations. Fair Value of Financial Instruments and Fair Value Measurements The Company determines the fair value of financial assets and liabilities using the fair value hierarchy established in the accounting standards. The hierarchy describes three levels of inputs that may be used to measure fair value, as follows: Level 1—Quoted prices in active markets for identical assets and liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. The carrying amounts of certain of the Company’s financial instruments, including cash equivalents, marketable securities, accounts receivable and accounts payable approximate fair value due to their short maturities. Net Income per Share Basic net income per share is calculated by dividing the net income by the weighted-average number of shares of common stock outstanding for the period. Diluted net income per share is computed by dividing the diluted net income by the weighted-average number of common shares outstanding for the period, including potential dilutive common shares assuming dilutive effect of outstanding common stock options, restricted stock units, shares issuable under the employee stock purchase program and common stock warrants using the treasury stock method. In periods when the Company has incurred a net loss, diluted net loss per share is the same as basic net loss per share because dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes . The standard is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, as well as improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The Company adopted this standard as of January 1, 2021. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt-Modifications and Extinguishments (Subtopic 470-50), Compensation- Stock Compensation (Topic 718), and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815- 40), which provides guidance on modifications or exchanges of a freestanding equity-classified written call options that are not within the scope of another Topic, such as warrants. The Company adopted this standard as of January 1, 2022 on a prospective basis to modifications or exchanges occurring on or after this date. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. Accounting Pronouncements Issued but Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard is intended to provide a better understanding of an entity's overall performance and business activities through improved disclosure about an entity's reportable segments, including more detailed information about reportable segment expenses. The new standard will be effective for the Company for the fiscal year beginning January 1, 2024. While the new standard does require additional footnote disclosure, the Company currently does not expect the adoption of the new standard to have a material effect on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Tax |
