The carrying amounts reported in the Condensed Consolidated Balance Sheet approximate the fair value based on quoted market prices or alternative pricing sources and models utilizing market observable inputs. As of March 31, 2020, the Company did not recognize any allowance for credit impairments on its available for sale debt securities. All investments in marketable securities are classified as current assets on the balance sheet because the underlying securities mature within one year from the balance sheet date.
