Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company invests its cash and cash equivalents into high credit quality security instruments. Deposits which exceed $250,000 at each institution are not insured by the Federal Deposit Insurance Corporation (“FDIC”). Of the $15.8 million in cash and cash equivalents at December 31, 2014, $15.3 million was not insured by the FDIC. Of the $23.6 million in cash and cash equivalents at December 31, 2013, $23.1 million was not insured by the FDIC.

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.
