Significant Accounting Policies | Significant Accounting Policies Basis of Presentation The Company’s interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial position and results of operations for the interim periods presented. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2019 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 24, 2020. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for a full year, any other interim periods or any future year or period. Principles of Consolidation The interim condensed consolidated financial statements include the accounts of Aerie and its wholly-owned subsidiaries. All intercompany accounts, transactions and profits have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of income and expenses during the reporting periods. Significant items subject to such estimates and assumptions include revenue recognition, stock-based compensation and fair value measurements. On March 11, 2020, the World Health Organization declared the coronavirus (“COVID-19”) outbreak a pandemic. The full extent to which COVID-19 will directly or indirectly impact our business, results of operations and financial condition, including net product revenue, cost and expenses, reserves and allowances, manufacturing and clinical trials, will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat it, as well as the economic impact on eye care professionals, patients, third parties and markets. Actual results could differ from the Company’s estimates. Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company views its operations and manages its business as one operating segment. Concentration of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and investments. The Company’s cash and cash equivalents, which include short-term highly liquid investments with original maturities of three months or less, are held at several financial institutions. The Company’s investment policy permits investments in U.S. federal government and federal agency securities, corporate bonds or commercial paper, money market instruments, and certain qualifying money market mutual funds, and places restrictions on credit ratings, maturities, and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash, cash equivalents and investments to the extent recorded on the condensed consolidated balance sheets. The Company relies on its third-party manufacturers to produce the active pharmaceutical ingredient (“API”) and final drug product for Rhopressa ® and Rocklatan ® and may rely on third-party manufacturers for its current and future product candidates. In addition to the current contract manufacturers, the Company obtained FDA approval for an additional Rocklatan ® drug product contract manufacturer in January 2020, which began to supply commercial product in the first quarter of 2020. In addition, the Company has established its own manufacturing plant in Athlone, Ireland, for commercial production of Rocklatan ® and future commercial production of Rhopressa ® , if approved, and thereafter, potentially Rhokiinsa ® and, if approved, Roclanda ® . In January 2020, the Company received FDA approval to produce Rocklatan ® at the Athlone plant for commercial distribution in the United States. The manufacturing plant began production of commercial supplies of Rocklatan ® during the first quarter of 2020. The Company expects FDA approval to produce Rhopressa ® at the Athlone plant by the end of 2020. The Company currently expects to continue to use product sourced from its contract manufacturers in addition to the Athlone plant. Revenue Recognition The Company accounts for its revenue transactions under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC Topic 606”). In accordance with ASC Topic 606, the Company recognizes revenues when its customers obtain control of its product for an amount that reflects the consideration it expects to receive from its customers in exchange for that product. To determine revenue recognition for contracts that are determined to be in scope of ASC Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies the performance obligation. The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. Once the contract is determined to be within the scope of ASC Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when such performance obligation is satisfied. Aerie’s customers include a limited number of national and select regional wholesalers (the “distributors”). These distributors subsequently resell the product, primarily to retail pharmacies that dispense the product to patients. Net product revenue is typically recognized when distributors obtain control of the Company’s products, which occurs at a point in time, typically upon delivery of product to the distributors. The Company evaluates the creditworthiness of each of its distributors to determine whether it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur. The Company does not assess whether a contract has a significant financing component if the expectation is such that the period between the transfer of the promised goods to the customer and the receipt of payment will be less than one year. Standard credit terms do not exceed 75 days. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that would have been recognized is one year or less or the amount is immaterial. Shipping and handling costs related to the Company’s product sales are included in selling, general and administrative expenses. The Company’s net product revenues through June 30, 2020 were generated through sales of Rhopressa ® , which was commercially launched in the United States in April 2018, and sales of Rocklatan ® , which was commercially launched in the United States in May 2019. Product revenue is recorded net of trade discounts, allowances, commercial and government rebates, co-pay program coupons, chargebacks, U.S. government funding requirements for the coverage gap (commonly called the “donut hole”) portion of the Medicare Part D program and estimated returns and other incentives. These reserves are classified as either reductions of accounts receivable or as current liabilities. The estimates of reserves established for variable consideration reflect current contractual and statutory requirements, known market events and trends, industry data, forecasted customer mix and lagged claims. The transaction price, which includes variable consideration reflecting the impact of discounts and allowances, may be subject to constraint and is included in the net product revenues only to the extent that it is probable that a significant reversal of the amount of the cumulative revenues recognized will not occur in a future period. Actual amounts may ultimately differ from these estimates. If actual results vary, estimates may be adjusted in the period such change in estimate becomes known, which could have an impact on earnings in the period of adjustment. See Note 3 for additional information. Credit Losses Trade accounts receivable : The allowance for doubtful accounts is based on the Company’s assessment of the collectability of customer accounts. The Company regularly reviews the allowance by considering factors such as historical experience, creditworthiness of its customers, the age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. Available-for-sale investments : The Company’s investments can consist of U.S. federal government and federal agency securities, corporate bonds or commercial paper, money market instruments and certain qualifying money market mutual funds. The investments are short-term in nature and are rated investment grade by at least one bond credit rating service. Inventories Inventories are stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first-out (“FIFO”) method. The Company analyzes its inventory levels at least quarterly and writes down inventory that is expected to expire prior to being sold, inventory in excess of expected sales requirements and inventory that fails to meet commercial sale specifications, with a corresponding charge to cost of goods sold. The determination of whether inventory costs will be realizable requires estimates by management of future expected inventory requirements based on sales forecasts. If actual net realizable value is less than the estimated amount or if actual market conditions are less favorable than the Company’s projections, additional inventory write-downs may be required. Charges for inventory write-downs are not reversed if it is later determined that the product is saleable. Production costs related to idle or underutilized capacity at the manufacturing plant in Athlone, Ireland, are not included in the cost of inventory but are charged directly to cost of goods sold on the condensed consolidated statements of operations and comprehensive loss in the period incurred. The idle capacity results from the manufacturing plant having commenced operations earlier in 2020 and not reaching full capacity. Prior to the date the Company obtains regulatory approval for its product candidates or its manufacturing facilities such as its manufacturing plant in Athlone, Ireland, manufacturing costs related to commercial production are expensed as pre-approval commercial manufacturing expense on the condensed consolidated statements of operations and comprehensive loss. Once regulatory approval is obtained, the Company capitalizes such costs as inventory on the condensed consolidated balance sheets. Property, Plant and Equipment, Net Property, plant and equipment is recorded at historical cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the related assets. Construction-in-progress reflects amounts incurred for property, plant or equipment construction or improvements that have not yet been placed in service and are not depreciated or amortized. Repairs and maintenance are expensed when incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the determination of net loss. Estimated useful lives by major asset category are as follows: Manufacturing equipment 10 years Laboratory equipment 7 years Furniture and fixtures 5 years Software, computer and other equipment 3 years Leasehold improvements Lower of estimated useful life or term of lease Leases The Company determines if an arrangement is a lease at inception. For each lease, the lease term is determined at the commencement date and includes renewal options and termination options when it is reasonably certain that the Company will exercise that option. Operating leases with lease terms greater than one year are included in operating lease right-of-use (“ROU”) assets and current and long-term operating lease liabilities in the Company’s condensed consolidated balance sheets. Operating lease ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term using an estimated rate of interest the Company would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. The operating lease ROU assets are based on the liability adjusted for any prepaid or deferred rent and lease incentives. The incremental borrowing rate was utilized to discount lease payments over the expected term given that the Company’s operating leases do not provide an implicit rate. The Company estimates the incremental borrowing rate to reflect the profile of secured borrowing over the expected term of the leases based on the information available at the later of the date of adoption or the lease commencement date. Rent expense for the operating lease is recognized on a straight-line basis over the lease term. The Company’s lease agreements have lease and non-lease components, which are generally accounted for as a single lease component. Non-lease components include lease operating expenses, which are variable costs under the Company’s current leases. For vehicle leases, the Company accounts for the lease and non-lease components as a single lease component and applies a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Investments The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase. The Company’s investments are comprised of commercial paper and corporate bonds that are classified as available-for-sale in accordance with the ASC Topic 320, Investments-Debt and Equity Securities . The Company classifies investments available to fund current operations as current assets on its condensed consolidated balance sheets. Investments are classified as long-term assets on the condensed consolidated balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year. Available-for-sale investments in debt securities are recorded at fair value, with unrealized gains or losses included in comprehensive loss on the condensed consolidated statements of operations and comprehensive loss and in accumulated other comprehensive loss on the condensed consolidated balance sheets. Realized gains and losses, interest income earned on the Company’s cash, cash equivalents and investments, and amortization or accretion of discounts and premiums on investments are included within other (expense) incom e, net. Interest income was $0.5 million and $1.6 million for the three and six months ended June 30, 2020, respectively, and $0.5 million and $1.4 million for the three and six months ended June 30, 2019 . R ealized gains and losses are determined using the specific identification method and are included as a component of other income (expense), net. Realized gains or losses were immaterial during the three and six months ended June 30, 2020 and 2019. Fair Value Measurements The Company records certain financial assets and liabilities at fair value in accordance with the provisions of ASC Topic 820, Fair Value Measurements and Disclosures . As defined in the guidance, fair value, defined as an exit price, represents the amount that would be received to sell an asset or pay to transfer a liability in an orderly transaction between market participants. As a result, fair value is a market-based approach that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering these assumptions, the guidance defines a three-tier value hierarchy that prioritizes the inputs used in the valuation methodologies in measuring fair value. • Level 1—Unadjusted quoted prices in active, accessible markets for identical assets or liabilities. • Level 2—Other inputs that are directly or indirectly observable in the marketplace. • Level 3—Unobservable inputs that are supported by little or no market activity. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The Company’s cash equivalents are carried at fair value according to the fair value hierarchy described above. The Company’s investments were valued utilizing Level 2 inputs and the Convertible Notes were valued utilizing Level 2 inputs as of June 30, 2020. There were no transfers between the different levels of the fair value hierarchy during the six months ended June 30, 2020 and 2019. Stock-Based Compensation The estimated fair value of options to purchase common stock is determined on the date of grant using the Black-Scholes option pricing model. The fair value of restricted stock awards (“RSAs”) and restricted stock units (“RSUs”), including restricted stock awards with non-market performance and service conditions (“PSAs”) are based on the market value of Aerie’s common stock on the date of grant. Stock-based compensation expense related to time-based stock options, RSAs and RSUs is expensed on a straight-line basis over the vesting period. For RSAs with non-market performance conditions, the Company evaluates the criteria for each grant to determine the probability that the performance condition will be achieved. Compensation expense for RSAs with non-market performance conditions is recognized over the respective service period when it is deemed probable that the performance condition will be satisfied. Upon issuance and at each reporting period, the fair value of each stock appreciation rights (“SARs”) award is estimated using the Black-Scholes option pricing model and is marked to market through stock-based compensation expense. SARs are liability-based awards as they may only be settled in cash. Convertible Notes Transaction The Company separately accounts for the liability and equity components of convertible notes transactions that can be settled in cash by allocating the proceeds from issuance between the liability component and the embedded conversion option in accordance with accounting for convertible debt instruments that may be settled in cash (including partial cash settlement) upon conversion. The value of the equity component is calculated by first measuring the fair value of the liability component, using the interest rate of a similar liability that does not have a conversion feature, as of the issuance date. The difference between the proceeds from the convertible debt issuance and the amount measured as the liability component is recorded as the equity component with a corresponding discount recorded on the debt. The Company recognizes amortization of the resulting discount using the effective interest method as interest expense on the condensed consolidated statements of operations and comprehensive loss. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The Company allocates issuance costs incurred to the liability and equity components. Issuance costs attributable to the liability component are amortized to expense over the respective term of the convertible notes, and issuance costs attributable to the equity component are netted with the respective equity component in additional paid-in capital. In September 2019, the Company purchased capped call options from financial institutions to minimize the impact of potential dilution of the Aerie’s common stock upon conversion of the Convertible Notes. The capped call options meet the definition of a derivative in accordance with ASC 815, Derivatives and Hedging (“ASC 815”), however, qualify for derivative scope exception under ASC 815 for instruments indexed to a company’s own stock. Accordingly, the premiums for the capped call options were recorded as additional paid-in capital on the Company’s condensed consolidated balance sheets as the options are settleable in Aerie common stock at the election of the Company. See Note 10 for additional information. Adoption of New Accounting Standards In August 2018, the FASB issued Accounting Standards Updated (“ASU”) 2018-13, Fair Value Measurement (Topic 820-10): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which changes the fair value measurement disclosure requirements of ASC Topic 820. Under ASU 2018-13, certain disclosure requirements for fair value measurements are eliminated, amended or added. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance became effective for the Company beginning on January 1, 2020 and prescribes different transition methods for the various provisions. The adoption of ASU 2018-13 did not have a material impact on the Company’s condensed consolidated financial statements and disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires that financial assets measured at amortized cost be presented at the net amount expected to be collected. Currently, U.S. GAAP delays recognition of the full amount of credit losses until the likelihood of the loss occurring is probable. Under this ASU, the income statement will reflect an entity’s current estimate of all expected credit losses. The measurement of expected credit losses will be based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses rather than as a direct write-down of the security. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses (“ASU 2018-19”), which clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. Further, in May 2019, the FASB issued ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326), Targeted Transition Relief (“ASU 2019-05”), which provides transition relief and allows entities to elect the fair value option on certain financial instrument. The guidance became effective for the Company beginning on January 1, 2020. The new guidance prescribes different transition methods for the various provisions. The adoption of ASU 2016-13, ASU 2018-19 or ASU 2019-05 did not have a material impact on the Company’s condensed consolidated financial statements and disclosures. Recent Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new ASU also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. These changes aim to improve the overall usefulness of disclosures to financial statement users and reduce unnecessary costs to companies when preparing the disclosures. The guidance is effective for the Company beginning on January 1, 2021 and prescribes different transition methods for the various provisions. The Company is currently evaluating the impact of ASU 2019-12 on its consolidated financial statements and disclosures. Net Loss per Common Share Basic net loss per common share (“Basic EPS”) is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities with the exception of warrants for common stock with a $0.05 exercise price, which are exercisable for nominal consideration and are therefore included in the calculation of the weighted average number of shares of common stock as common stock equivalents. Diluted net loss per share (“Diluted EPS”) gives effect to all dilutive potential shares of common stock outstanding during this period. For Diluted EPS, net loss used in calculating Basic EPS may be adjusted for certain items related to the dilutive securities. For all periods presented, Aerie’s potential common stock equivalents have been excluded from the computation of Diluted EPS as their inclusion would have had an anti-dilutive effect. The potential common stock equivalents that have been excluded from the computation of Diluted EPS consist of the following: THREE MONTHS ENDED SIX MONTHS ENDED 2020 2019 2020 2019 Outstanding stock options 8,628,753 7,514,268 8,628,753 7,514,268 Stock purchase warrants 4,500 79,500 4,500 79,500 Non-vested restricted stock awards and performance share units 578,923 728,705 578,923 728,705 Non-vested restricted stock units 30,827 — 30,827 — Total 9,243,003 8,322,473 9,243,003 8,322,473 |
