Debt Disclosure [Text Block]	11. Borrowings On November 22, 2011, we signed an amendment to renew our existing three-year $20,000,000 credit facility (the “TD Bank Credit Facility”) with TD Bank. The TD Bank Credit Facility provides for a $20,000,000 revolving credit line expiring on November 28, 2014. Borrowings under the revolving credit line bear a floating rate of interest at the prime rate minus one percent and are secured by a lien on all of our assets. We also pay a fee of 0.25% on unused borrowings under the revolving credit line. The total deferred financing costs relating to expenses incurred to complete the TD Bank Credit Facility was $31,000 which will be amortized over the three year term. The TD Bank Credit Facility imposes certain quarterly financial covenants on us and restricts, among other things, our ability to incur additional indebtedness, the payment of dividends on our common stock and the creation of other liens. We were in compliance with all financial covenants of the TD Bank Credit Facility at December 31, 2011. As of December 31, 2011, undrawn commitments under the TD Bank Credit Facility were $20,000,000.
