At September 30, 2022, substantially all of the Company’s interest-bearing cash equivalent balances, were concentrated in one U.S. Government institutional money market fund that had investments consisting primarily of U.S. Government Agency debt, U.S. Treasury Repurchase Agreements and U.S. Government Agency Repurchase Agreements. Generally, these deposits may be redeemed upon demand and, therefore, the Company believes they have minimal risk. Marketable securities consist of investments with an original or remaining maturity of greater than three months but less than one year at the date of purchase. The Company had investments of $81.9 million in marketable securities at September 30, 2022.

At December 31, 2021, a total of $155.6 million, or 90.4% of the Company’s interest-bearing cash equivalent balances, were concentrated in one U.S. Government institutional money market fund that had investments consisting primarily of U.S. Government Agency debt, U.S. Treasury debt, U.S. Treasury Repurchase Agreements and U.S. Government Agency Repurchase Agreements. $16.5 million, or 9.6% of the Company’s interest-bearing cash equivalent balances consisted of investment-grade commercial paper. Generally, these investments may be sold upon demand and, therefore, the Company believes they have minimal risk. The Company had investments of $33.0 million in marketable securities at December 31, 2021.

The Company’s cash equivalents and marketable securities are classified within Level 1 or Level 2 on the basis of valuations using quoted market prices or alternative pricing sources and models utilizing market observable inputs, respectively. The marketable securities have been valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. Inputs to the models may include, but are not limited to, reported trades, executable bid and ask prices, broker/dealer quotations, prices or yields of securities with similar characteristics, benchmark curves or information pertaining to the issuer, as well as industry and economic events. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security, and have been classified as Level 2.

The carrying amounts of accounts receivable, accounts payable and accrued expenses approximate fair value because of their short-term maturity.

The carrying amounts of the short-term borrowings and long-term debt under the Company’s SVB Loan Agreement approximate the estimated fair value. These borrowings under the Credit Facilities have a variable interest rate structure and are classified within Level 2 of the fair value hierarchy.
