3.Cash, Cash Equivalents and Investments
The Company currently invests its excess cash in bank certificates of deposit (“CDs”) that are fully insured by the Federal Deposit Insurance Corporation (“FDIC”) and Unites States Treasury (“Treasuries”) securities with terms of
fiveyears, as well as money market accounts. CDs and Treasuries with original maturities of more than
threemonths are reported as held-to-maturity investments and are recorded at amortized cost, which approximates fair value due to the negligible risk of changes in value due to interest rates.
The maturity dates of the Company’s investments as of
March 31, 2020and
September 30, 2019are as follows:
The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify.
