Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of Intra-Cellular Therapies, Inc. and its wholly own subsidiaries have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative United States generally accepted accounting principles set forth in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). All intercompany accounts and transactions have been eliminated in consolidation. The Company currently operates in one operating segment. Operating segments are defined as components of an enterprise about which separate discrete information is available for the chief operating decision maker, or decision making group, in deciding how to allocate resources and assessing performance. The Company views its operations and manages its business in one segment, which is discovering and developing drugs for the treatment of neurological and psychiatric disorders. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Although actual results could differ from those estimates, management does not believe that such differences would be material. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of checking accounts, money market accounts, money market mutual funds, and certificates of deposit with a maturity date of three months or less. The carrying values of cash and cash equivalents approximate the fair market value. Certificates of deposit, commercial paper, corporate notes and corporate bonds with a maturity date of more than three months are classified separately on the balance sheet. Investment Securities Investment securities consisted of the following (in thousands): September 30, 2019 Amortized Cost Unrealized Gains Unrealized (Losses) Estimated Fair Value (Unaudited) U.S. Government Agency Securities $ 55,402 $ 70 $ (13 ) $ 55,459 Certificates of Deposit 3,000 — — 3,000 Commercial Paper 33,705 16 (6 ) 33,715 Corporate Notes/Bonds 60,965 135 (3 ) 61,097 $ 153,072 $ 221 $ (22 ) $ 153,271 December 31, 2018 Amortized Cost Unrealized Gains Unrealized (Losses) Estimated Fair Value U.S. Government Agency Securities $ 124,691 $ 24 $ (289 ) $ 124,426 FDIC Certificates of Deposit (1) 245 — — 245 Certificates of Deposit 1,000 — — 1,000 Commercial Paper 41,317 — (45 ) 41,272 Corporate Notes/Bonds 125,998 7 (365 ) 125,640 $ 293,251 $ 31 $ (699 ) $ 292,583 (1) “FDIC Certificates of Deposit” consist of deposits that are less than $250,000. The Company has classified all of its investment securities available-for-sale, available-for-sale The Company monitors its investment portfolio for impairment quarterly or more frequently if circumstances warrant. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, the Company records an impairment charge within earnings attributable to the estimated loss. In determining whether a decline in the value of an investment is other-than-temporary, the Company evaluates currently available factors that may include, among others: (1) general market conditions; (2) the duration and extent to which fair value has been less than the carrying value; (3) the investment issuer’s financial condition and business outlook; and (4) the Company’s assessment as to whether it is more likely than not that the Company will be required to sell a security prior to recovery of its amortized cost basis. As of September 30, 2019, the aggregate related fair value of investments with unrealized losses was $36 million and the aggregate amount of unrealized losses was approximately $22,000. Of the $36 million, $10 million has been held in a continuous unrealized loss position for less than 12 months and $26 million has been held in a continuous loss position for 12 months or longer. The total continuous unrealized loss for investments held for 12 months or longer is approximately $16,000 as of September 30, 2019. As of December 31, 2018, the Company had approximately $92.1 million of investments with a continuous unrealized loss for 12 months or longer of approximately $345,000. The Company attributes the unrealized gains and losses on the available-for-sale Fair Value Measurements The Company applies the fair value method under ASC Topic 820, Fair Value Measurements and Disclosures • Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets and liabilities. • Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets and liabilities in inactive markets. Related inputs can also include those used in valuation or other pricing models, such as interest rates and yield curves that can be corroborated by observable market data. • Level 3—Fair value is determined by inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgments to be made by a reporting entity—e.g., determining an appropriate adjustment to a discount factor for illiquidity associated with a given security. The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the ASC Topic 820 hierarchy. The Company has no assets or liabilities that were measured using quoted prices for significant unobservable inputs (Level 3 assets and liabilities) as of September 30, 2019 and December 31, 2018. The carrying value of cash held in money market funds of approximately $55.4 million as of September 30, 2019 and $39.6 million as of December 31, 2018 is included in cash and cash equivalents and approximates market value based on quoted market prices (Level 1 inputs). The carrying value of cash held in certificates of deposit of approximately $39.0 million and $7.5 million as of September 30, 2019 and December 31, 2018, respectively, is included in cash and cash equivalents and approximates market value based due to their short term maturities.

Management believes that the risks associated with its financial instruments are minimal as the counterparties are various corporations, financial institutions and government agencies of high credit standing. Concentration of Credit Risk Cash equivalents are held with major financial institutions in the United States. Certificates of deposit, cash and cash equivalents held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and, therefore, bear minimal risk. Accounts Receivable Accounts receivable that management has the intent and ability to collect are reported in the balance sheets at outstanding amounts, less an allowance for doubtful accounts. The Company writes off uncollectible receivables when the likelihood of collection is not probable. The Company evaluates the collectability of accounts receivable on a regular basis. The allowance, if any, is based upon various factors including the financial condition and payment history of customers, an overall review of collections experience on other accounts and economic factors or events expected to affect future collections experience. No allowance was recorded as of September 30, 2019 and December 31, 2018, as the Company has a history of collecting on all its accounts including from government agencies and collaborations funding its research. As of September 30, 2019 and December 31, 2018, the Company did not have accounts receivable. Property and Equipment Property and equipment is stated at cost and depreciated on a straight-line basis over estimated useful lives ranging from three When indicators of possible impairment are identified, the Company evaluates the recoverability of the carrying value of its long-lived assets based on the criteria established in ASC Topic 360, Property, Plant and Equipment Research and Development Except for payments made in advance of services, the Company expenses its research and development costs as incurred. For payments made in advance, the Company recognizes research and development expense as the services are rendered. Research and development costs primarily consist of salaries and related expenses for personnel and resources and the costs of clinical trials. Other research and development expenses include preclinical analytical testing, manufacturing of drug product, outside service providers, materials and consulting fees. Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as subject enrollment, clinical site activations or information provided to the Company by its vendors with respect to their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development expense, as the case may be. As part of the process of preparing its financial statements, the Company is required to estimate its expenses resulting from its obligations under contracts with vendors, clinical research organizations and consultants and under clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. The Company’s objective is to reflect the appropriate clinical trial expenses in its financial statements by matching those expenses with the period in which services are performed and efforts are expended. The Company accounts for these expenses according to the progress of the clinical trial as measured by subject progression and the timing of various aspects of the trial. The Company determines accrual estimates through financial models taking into account various clinical information provided by vendors and discussion with applicable personnel and external service providers as to the progress toward or state of completion of trials, or the services completed. During the course of a clinical trial, the Company adjusts its clinical expense recognition if actual results differ from its estimates. The Company makes estimates of its accrued expenses as of each balance sheet date based on the facts and circumstances known to it at that time. The Company’s clinical trial accruals are dependent upon the timely and accurate reporting of contract research organizations, clinical sites and other third-party vendors. Although the Company does not expect its estimates to be materially different from amounts actually incurred, its understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in it reporting amounts that are too high or too low for any particular period. For the three and nine months ended September 30, 2019 and 2018, there were no material adjustments to the Company’s prior period estimates of accrued expenses for clinical trials. Income Taxes Income taxes are accounted for using the liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce net deferred tax assets to the amount expected to be realized. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company accounts for uncertain tax positions pursuant to ASC Topic 740. Financial statement recognition of a tax position taken or expected to be taken in a tax return is determined based on a more-likely-than-not On December 22, 2017, President Trump signed into law the “Tax Cuts and Jobs Act” (“TCJA”) that significantly reforms the Internal Revenue Code of 1986, as amended (the “Code”). The TCJA, among other things, includes changes to U.S. federal tax rates, imposes significant additional limitations on the deductibility of interest and net operating loss carryforwards, allows for the expensing of capital expenditures, and puts into effect the migration from a “worldwide” system of taxation to a territorial system. In addition, the TCJA repealed the alternative minimum tax (“AMT”) and provides for a refund of taxes paid between 2018 and 2021. With the passing of the TCJA, the Company will receive refunds in future periods for AMT paid in prior years. The Company therefore recognized a benefit of approximately $1.1 million for these taxes for the year ended December 31, 2017. We received approximately $529,000 in the third quarter of 2019. As of September 30, 2019 , The Company’s effective tax rate for the nine months ended September 30, 2019 and 2018 was approximately 0% for both periods, respectively. The Company’s annual effective tax rate of approximately 0% is substantially lower than the U.S. statutory rate of 21% due to valuation allowances recorded on current year losses where the Company is not at more-likely than not to recognize a future tax benefit. Comprehensive Income (Loss) All components of comprehensive income (loss), including net income (loss), are reported in the financial statements in the period in which they are incurred. Comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner Share-Based Compensation Share-based payments are accounted for in accordance with the provisions of ASC Topic 718, Compensation—Stock Compensation For all awards granted with time based vesting conditions, expense is amortized using the straight-line attribution method. Share-based compensation expense recognized in the statements of operations for the three and nine months ended September 30, 2019 and 2018 is based on share-based awards ultimately expected to vest. The Company utilizes the Black-Scholes model for estimating fair value of its stock options granted. Option valuation models, including the Black-Scholes model, require the input of subjective assumptions, and changes in the assumptions used can materially affect the grant date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award. Expected volatility rates are based on a combination of the historical volatility of the common stock of comparable publicly traded entities and the historical information about the Company’s common stock. The expected life of stock options is the period of time for which the stock options are expected to be outstanding. Given the limited historical exercise data, the expected life is determined using the “simplified method,” which defines expected life as the midpoint between the vesting date and the end of the contractual term. The risk-free interest rates are based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The Company has not paid dividends to its stockholders since its inception and does not plan to pay cash dividends in the foreseeable future. Therefore, the Company has assumed an expected dividend rate of zero. For stock options granted, the exercise price was determined by using the closing market price of the Company’s common stock on the date of grant. The Company recognizes the effect of forfeitures when they occur. A restricted stock unit (“RSU”) is a stock-based award that entitles the holder to receive shares of the Company’s common stock as the award vests. The fair value of each RSU is based on the fair market value of the Company’s common stock on the date of grant. The Company has granted RSUs that vest in three equal annual installments provided that the grantee in the service of In the first quarter of each fiscal year beginning in 2016, the Company granted time based RSUs that vest in three the Company granted performance-based RSUs, which vest based on the achievement of certain milestones that include (i) the submission of a new drug application (“NDA”) with the U.S. Food and Drug Administration (the “FDA”), (ii) the approval of the NDA by the FDA (together, the “Milestone RSUs”) and (iii) the achievement of certain comparative shareholder returns against the Company’s peers (the “TSR RSUs”). The Milestone RSUs were valued at the closing price on March 8, 2017. The Milestone RSUs related to the NDA submission have been fully amortized through December 31, 2018. The NDA submission milestone was achieved in the third quarter of 2018, so the Milestone RSUs related to the NDA submission vested on December 31, 2018. The amortization of the expenses for RSUs related to the approval of the NDA will commence if and when the NDA submission has been approved through the last day of the calendar year in which the milestone is achieved and expires on December 31, 2019 if not achieved. The TSR RSUs were valued using the Monte Carlo Simulation method and will be amortized over the life of the RSU agreements which ends December 31, 2019. The Milestone RSUs and TSR RSUs are target based and the ultimate awards, if attained, could be the target amount or higher or lower than the target amount, depending on the timing or achievement of the goal. Under ASC Topic 718, the cumulative amount of compensation cost recognized for instruments classified as equity that ordinarily would result in a future tax deduction under existing tax law shall be considered to be a deductible difference in applying ASC Topic 740, Income Taxes Since the Company had net operating loss carryforwards as of September 30, 2019 and 2018, no excess tax benefits for the tax deductions related to share-based awards were recognized in the statements of operations. Loss Per Share Basic net loss per common share is determined by dividing the net loss by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common stock equivalents outstanding for the period. The treasury stock method is used to determine the dilutive effect of the Company’s stock option grants and RSUs. The following common stock equivalents were excluded in the calculation of diluted loss per share because their effect would be anti-dilutive as applied to the loss from operations for the three and nine months ended September 30, 2019 and 2018: Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Stock options 283,129 872,246 305,810 871,844 RSUs 459,946 387,953 512,749 372,744 TSR RSUs 79,182 75,143 89,139 75,143 Recently Issued Accounting Standards In May 2014, the FASB issued ASC Update No. 2014-09, The Company adopted this standard using the “modified retrospective method,” which did not result in an impact to its financial statements as the Company has not had product sales to date. Upon commercializing a product or executing any revenue generating contracts, the Company will provide additional disclosures in the notes to the consolidated financial statements related to the relevant aspects of any revenue generating contracts that the Company has entered In February 2016, the FASB issued ASU No. 2016-02, 2016-02”). 2016-02 2016-02 , The adoption of the standard resulted in recognition of additional net lease assets and lease liabilities of approximately $20.2 million and $23.4 million, respectively, as of January 1, 2019.
