Basis of Presentation | Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Vanda Pharmaceuticals Inc. and its wholly-owned subsidiaries and have been prepared in accordance with United States generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company’s consolidated financial statements and accompanying notes included in the Company’s annual report on Form 10-K (Annual Report) for the fiscal year ended December 31, 2023. The financial information as of March 31, 2024 and for the three months ended March 31, 2024 and 2023 is unaudited, but in the opinion of management, all adjustments considered necessary for a fair statement of the results for these interim periods have been included. All intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated balance sheet data as of December 31, 2023 was derived from audited financial statements but does not include all disclosures required by GAAP. The results of the Company’s operations for any interim period are not necessarily indicative of the results that may be expected for any other interim period or any future year or period.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates that affect the reported amounts of assets and liabilities at the date of the financial statements, disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses during the reporting period. Management continually re-evaluates its estimates, judgments and assumptions, and management’s evaluation could change. Actual results could differ from those estimates.
Cash, Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash For purposes of the Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Cash Flows, cash equivalents represent highly-liquid investments with a maturity date of three months or less at the date of purchase. Cash and cash equivalents include investments in money market funds with commercial banks and financial institutions, and commercial paper of high-quality corporate issuers. Restricted cash relates primarily to amounts held as collateral for letters of credit for leases for office space at the Company’s Washington, D.C. headquarters.
Major Customers | Major Customers Fanapt® is available in the U.S. for distribution through a limited number of wholesalers and is available in retail pharmacies. HETLIOZ® is available in the United States (U.S.) for distribution through a limited number of specialty pharmacies and is not available in retail pharmacies. PONVORY® is available in the U.S. for distribution primarily through specialty distributors. The Company invoices and records revenue when its customers, wholesalers, specialty pharmacies and specialty distributors, receive product from the third-party logistics warehouse, which is the point at which control is transferred to the customer. Outside the U.S., the Company has a distribution agreement for the commercialization of Fanapt® in Israel and sells HETLIOZ® in Germany. There were five major customers that each accounted for more than 10% of total revenues and, as a group, represented 72% of total revenues for the three months ended March 31, 2024. There were five major customers that each accounted for more than 10% of accounts receivable and, as a group, represented 71% of total accounts receivable at March 31, 2024. Receivables are carried at transaction price net of allowance for credit losses. Allowance for credit losses is measured using historical loss rates based on the aging of receivables and incorporating current conditions and forward-looking estimates.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which is intended to provide enhanced segment disclosures. The standard will require disclosures about significant segment expenses and other segment items and identifying the Chief Operating Decision Maker and how they use the reported segment profitability measures to assess segment performance and allocate resources. These enhanced disclosures are required for all entities on an interim and annual basis, even if they have only a single reportable segment. The standard is effective for years beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024 and early adoption is permitted. The Company is evaluating this standard to determine if adoption will have a material impact on the Company’s consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to provide enhancements to annual income tax disclosures. The standard will require more detailed information in the rate reconciliation table and for income taxes paid, among other enhancements. The standard is effective for years beginning after December 15, 2024 and early adoption is permitted. The Company is evaluating this standard to determine if adoption will have a material impact on the Company’s consolidated financial statements.
Marketable Securities | The Company’s assets classified in Level 1 and Level 2 as of March 31, 2024 and December 31, 2023 consist of cash equivalents and available-for-sale marketable securities. The valuation of Level 1 instruments is determined using a market approach and is based upon unadjusted quoted prices for identical assets in active markets. The valuation of Level 2 instruments is also determined using a market approach based upon quoted prices for similar assets in active markets, or other inputs that are observable for substantially the full term of the financial instrument. Level 2 securities include certificates of deposit, commercial paper and corporate notes that use as their basis readily observable market parameters.
Earnings per Share | Earnings per Share Basic earnings per share (EPS) is calculated by dividing the net income (loss) by the weighted average number of shares of common stock outstanding. Diluted EPS is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding, plus potential outstanding common stock for the period. Potential outstanding common stock includes stock options and shares underlying RSUs, but only to the extent that their inclusion is dilutive, as calculated using the treasury stock method.
