The term "cash reserves" is not a standard accounting term or classification. "Cash reserves" is commonly used to refer to funds set aside by a company or organization for specific purposes, such as contingencies, future investments, or working capital needs. These reserves are typically considered as part of a company's cash and cash equivalents.
Under GAAP, cash (and cash equivalents) includes currency on hand, deposits in bank accounts, and any highly liquid investments that have an original maturity of three months or less. Cash equivalents are short-term investments that are readily convertible to known amounts of cash and have original maturities of three months or less from the date of purchase
