Kodiak Sciences Inc. Notes to Consolidated Financial Statements (in thousands, except share and per share data) 113 Net Loss per Share Attributable to Common Stockholders Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For purposes of this calculation, the redeemable convertible preferred stock, preferred stock warrants, convertible notes, common stock subject to repurchase, and stock options are considered to be potentially dilutive securities. Basic and diluted net loss attributable to common stockholders per share is presented in conformity with the two-class method required for participating securities as the redeemable convertible preferred stock is considered a participating security. The Company’s participating securities do not have a contractual obligation to share in the Company’s losses. As such, the net loss is attributed entirely to common stockholders. Since the Company has reported net loss for all periods presented, diluted net loss per share is the same as basic net loss per common share for those periods. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by the FASB, under its ASC or other standard setting bodies, and adopted by the Company as of the specified effective date, unless otherwise discussed below. Recently Adopted Accounting Pronouncements In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718), Scope of Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments in this update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. The Company adopted this new guidance beginning January 1, 2018, on a prospective basis, which did not result in a material impact on its consolidated financial statements and related disclosures. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. The amendments of this standard provide guidance on restricted cash disclosures and presentation in the statement of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU 2016-18 effective January 1, 2018, which required the change in restricted cash to be included as part of the total change in cash and cash equivalents on the statement of cash flows. While restricted cash is still presented as a separate line item in the Company’s balance sheet, it will no longer be presented as a separate item in the statements of cash flows. This did not result in a material impact on the Company’s consolidated financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this new guidance beginning January 1, 2018, which did not result in a material impact on its consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which requires changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update are effective for interim and annual periods beginning after December 15, 2017. The Company adopted this new guidance beginning January 1, 2018, on a retrospective basis, which did not result in a material impact on its consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The updated guidance enhances the reporting model for financial instruments, which includes amendments to address aspects of recognition, measurement, presentation and disclosure. The amendment to the standard is effective for financial statements issued for interim and annual periods beginning after December 15, 2017. The Company adopted this new guidance beginning January 1, 2018, on a retrospective basis, which did not result in a material impact on its consolidated financial statements and related disclosures.
