credit facility we entered into a $ 50 million credit agreement with a commercial bank in march 2007. the loan is a revolving facility the proceeds of which may be used for our working capital , capital expenditures , and general corporate purposes . the facility terminates on june 30 , 2013. advances are made pursuant to a borrowing base . advances are secured by a perfected first priority security interest in our accounts receivable and inventory . the interest rate floats at certain margins over libor or base rate based upon the leverage ratio from time to time . there is an unused commitment fee . the ratio of total funded debt to ebitda may not be less than 3:1. we had no borrowings under this credit facility at december 31 , 2012 , 2011 , or 2010. we intend to fund future capital requirements for our businesses from cash flow generated by us as well as from existing cash , cash investments , and , if the need should arise , borrowings under our credit facility . we do not believe there will be a need to issue any securities to fund such capital requirements . department of energy grant we entered into a contract with a customer to design , construct , and operate a commercial-scale plant to produce intermediate anode powder as a component of high-performance graphite anode materials for lithium-ion batteries . in connection with this contract , we applied for a financial assistance award under the electric drive vehicle battery and component manufacturing initiative administered by the department of energy national energy technology laboratory on behalf of the office of energy efficiency and renewable energy . an award was granted to us in the amount of $ 12,600,000 , which we accepted on july 27 , 2010. the funds were to be used to modify existing idle assets and to acquire and construct new assets to be used for the production of specialized materials for lithium-ion batteries for electric cars and other applications . we receive grant monies on a cost share basis as we incur construction-related expenditures . the amounts received under this arrangement are recorded as deferred revenue and are amortized into earnings over the anticipated life of the customer relationship . such amortization began once construction was completed and the plant was placed into service . this occurred in the third quarter of 2011. through december 31 , 2011 ,

cash dividend and in 2011 and 2012 as regular cash dividends . regular cash dividends will also be paid in 2013 as previously discussed . we intend to retain the remaining cash to fund infrastructure and capacity expansion at our batesville plant . third parties have not placed significant restrictions on our working capital management decisions . 35 a significant portion of these funds were held

classify these investments as current assets in the accompanying consolidated balance sheets and designate them as being “ available-for-sale ” . accordingly , they are recorded at fair value , with the unrealized gains and losses , net of taxes , reported as a component of stockholders ' equity . the fair value of these preferred stock , trust preferred securities , and other equity instruments

an 11 % reduction . this reduction in cost of goods sold and distribution was primarily due to reduced sales volumes of certain chemical products including the bleach activator and the proprietary herbicide . further reductions in cost of good sold and distribution resulted from adjustments in our inventory carrying value as determined utilizing the lifo method of inventory accounting . on a percentage basis , the 11 % reduction in costs of goods sold and distribution in 2012 as compared to 2011 was greater than the 5 % reduction in chemical segment revenues due to increased per unit sales prices of certain chemical products as compensation for lower quantities of material purchased and inflationary price adjustments . cost of goods sold and distribution for 2012 for our biofuel

effect , this credit was recorded as a reduction in cost of goods sold and distribution expense in our consolidated statement of operations . after its expiration , no related reduction to cost of goods sold and distribution expense was recorded . the existence of this credit was a significant factor in the profitability of biodiesel production . further reducing 2012 biofuel gross margin relative to its gross margin in 2011 was a reduction in 2012 of the amount we were awarded under the usda section 9005 – advanced biofuel producers program . in 2011 we were awarded approximately $ 1,900,000 and in 2012 we were awarded $ 753,000 under this program . this award is recorded as a reduction in our cost of goods sold and distribution expense in the period funding is received . 40

allowance of $ 25,000 at december 31 , 2011. no such valuation allowance was recorded at december 31 , 2012. on december 31 , 2011 , a tax credit for small agri-biodiesel producers with production
