Fair Value Measurements

Note 3. Fair Value Measurements

Financial assets and liabilities are recorded at fair value. The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value.

Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

During the periods presented, the Company has not changed the manner in which it values assets and liabilities that are measured at fair value. The Company recognizes transfers between levels of the fair value hierarchy as of the end of the reporting period. There were no transfers within the hierarchy as of June 30, 2021 and December 31, 2020. The following tables set forth the Company’s financial instruments that were measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands):

Investments in marketable securities are classified as available-for-sale. At June 30, 2021 and December 31, 2020, the balance in the Company’s accumulated other comprehensive income comprised activity related to the Company’s available-for-sale marketable securities. There were immaterial realized gains or losses recognized on the sale or maturity of available-for-sale marketable securities as of June 30, 2021 and December 31, 2020, and as a result, the Company did not reclassify any amounts out of accumulated other comprehensive income for the periods then ended. The Company has a limited number of available-for-sale marketable securities in loss positions as of June 30, 2021, which the Company does not intend to sell and has concluded it will not be required to sell before recovery of the amortized cost for the investment at maturity. The fair value and amortized cost of investments in marketable securities by major security type as of June 30, 2021 and December 31, 2020 are presented in the tables that follow (in thousands):
