We base these estimates on historical and anticipated results, trends, and other assumptions with respect to future events that we believe are reasonable and evaluate our estimates on an ongoing basis.

The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits. The Company manages its credit risk associated with cash concentrations by concentrating its cash deposits in high-quality financial institutions and by periodically evaluating the credit quality of the primary financial institutions holding such deposits. The carrying value of cash approximates fair value. Our investment portfolio is comprised of highly rated securities with a weighted-average maturity of less than 12 months in accordance with our investment policy which seeks to preserve principal and maintain a high degree of liquidity. Historically, the Company has not experienced any losses due to such cash concentrations. The Company does not have any off-balance-sheet credit exposure related to its customers. Concentrations of credit risk with respect to accounts receivable and revenue are limited due to a large, diverse customer base. We do not require collateral from clients. We maintain an allowance for credit losses based upon the expected collectability of accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains allowances for possible losses, which, when realized, have been within the range of management’s expectations.
