Cash and Cash Equivalents	3. Cash and Cash Equivalents The Company considers all highly liquid instruments purchased with a maturity of three months or less to be cash equivalents. The Company invests cash in excess of operating requirements in income-producing short-term investments. Money market funds of less than $0.3 million and $0.1 million were included in cash and cash equivalents in the accompanying condensed consolidated balance sheets at October 31, 2015 and July 31, 2015, respectively.

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.
