Concentration of Risk [Abstract]
CONCENTRATION OF RISK	NOTE 13—CONCENTRATION OF RISK The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash. The Company maintains its cash at banks and financial institutions it considers to be of high credit quality; however the Company’s cash deposits may at times exceed the FDIC insured limit. The Company’s deposits at banks in excess of the FDIC insured limit are maintained in sweep accounts that are collateralized by overnight repurchase agreements. The Company has not experienced losses on these accounts, and management believes that the Company is not exposed to significant risks on such accounts.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
