Cash and Cash Equivalents [Abstract]
Cash and Cash Equivalents	NOTE 2 – Cash and Cash Equivalents The Company considers all highly liquid investments purchased with original maturities of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents include cash held in checking, domestic certificates of deposit, and money market accounts. The Company periodically invests its excess cash in money market funds and U.S. Treasury Bills. The Company’s cash and cash equivalents are placed with high credit quality financial institutions.

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.
