The amortized cost of marketable securities is adjusted for amortization of premiums and accretion of discounts to maturity. At June 30, 2021, the balance in accumulated other comprehensive loss was comprised solely of activity related to marketable securities. There were no realized gains or losses recognized on the sale or maturity of marketable securities for the six months ended June 30, 2021 and 2020 and, as a result, the Company did not reclassify any amounts out of accumulated other comprehensive loss for the same periods. Pursuant to the adoption of ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, the Company records changes in the fair value of its investments in corporate equity securities to “Other income (expense), net” in the Company’s condensed consolidated statements of operations. The Company holds debt securities of companies with high credit quality and has determined that there was no material change in the credit risk of any of its debt securities. The contractual maturity dates of all the investments are less than one year.
