Concentration Of Credit Risk [Abstract] |
Concentration Of Credit Risk | 15. 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. On November 9, 2010, the Federal Deposit Insurance Corporation, ("FDIC") issued a Final Rule implementing section 343 of the Dodd-Frank Wall Street Reform and Consumer Protection Act that provides for unlimited insurance coverage of noninterest-bearing transaction accounts. Beginning December 31, 2010, through December 31, 2012, all noninterest bearing transaction accounts are fully insured, regardless of the balance of the account, at all FDIC insured institutions. All other deposits which exceed $250,000, including noninterest bearing transaction accounts prior to December 31, 2010, at each institution are not insured by the FDIC. Of the $20.8 million in cash and cash equivalents on the Consolidated Balance Sheets at December 31, 2012, $3.2 million was not insured by the FDIC. Of the $18.0 million in cash and cash equivalents at December 31, 2011, $1.2 million was not insured by the FDIC. As scheduled, the unlimited insurance coverage for noninterest-bearing transaction accounts provided under the Dodd-Frank Wall Street Reform and Consumer Protection Act expired on December 31, 2012. Deposits held in noninterest-bearing transaction accounts are now aggregated with any interest-bearing deposits the owner may hold in the same ownership category, and the combined total insured up to at least $250,000. Of the $20.8 million in cash and cash equivalents on the Consolidated Balance Sheets at December 31, 2012, $20.3 million was not insured by the FDIC after the expiration of unlimited coverage for noninterest-bearing transaction accounts.
