the ratio of total funded debt to ebitda may not be more than 3:1. we had no borrowings under this credit facility at december 31 , 2013 , 2012 , or 2011. 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 received grant monies on a cost share basis as we incurred construction-related expenditures . on july 29 , 2013 , futurefuel received notice from a chemicals segment customer for the intermediate anode powder that the customer will terminate the contract in accordance with its terms effective august 9 , 2014. futurefuel does not expect additional material to be produced or sold in 2013 or 2014 under that agreement . termination of this sales contract also may affect the terms of the grant received by futurefuel from the u.s. department of energy related to construction of the equipment utilized to produce the intermediate anode powder . as a result of this notice , futurefuel assessed the carrying values of its fixed assets and deferred revenue associated with this product and recorded an impairment loss of $ 17,580,000 for the equipment and recorded a reduction of deferred revenue as an element of cost of goods sold slightly offset by other expenses in the amount of $ 16,160 in the third quarter of 2013. the net impact of this impairment was recorded in cost of goods sold for $ 1,420,000. futurefuel 's customer remains liable for the payment of a minimum take or pay quantity per the terms of the sales agreement through the termination date . dividends in 2013 , we declared a special cash dividend aggregating $ 0.25 per share on our common stock , with a record date and payment date previously

management as a result of our initial equity offering , our subsequent positive operating results , the exercise of warrants , and the issuance of shares in our at-the-market offering , we accumulated excess working capital . some of this excess working capital was paid out in 2011 , 2012 , and 2013 as special cash dividends and as regular cash dividends . regular cash dividends will also be paid in 2014 as previously discussed . we intend to retain the remaining cash to fund infrastructure and capacity expansion at our batesville plant or to otherwise fund our future growth . third parties have not placed significant restrictions on our working capital management decisions . a significant portion of these funds were held in cash or cash equivalents at multiple financial institutions . in 2013 and 2012 , we also had investments in certain preferred stock , trust preferred securities and other equity instruments . in 2013 , we also had investments in exchange traded debt . we 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 , exchange traded debt , and

rate securities at december 31 , 2012. we have selectively made investments in certain auction rate securities that we believed offered sufficient yield along with sufficient liquidity . to date , all the auction rate securities in which we have invested have maintained a mechanism for liquidity , meaning that the respective auctions have not failed , the issuers have called the instruments , or a secondary market exists for liquidation of the securities . we have classified these instruments as current assets in the accompanying consolidated balance sheet and carried them at their estimated fair market value . story_separator_special_tag cost of goods sold and distribution for 2013 for our chemicals segment totaled $ 106,793,000 as compared to cost of goods sold and distribution for 2012 of $ 111,789,000 , a 4 % 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 4 % reduction in costs of goods sold and distribution in 2013 as compared to 2012 was greater than the 1 % increase in chemical segment revenues due to increased 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 2013 for our biofuel segment were $ 237,961,000 as compared to cost of good sold and distribution for 2012 of $ 182,787,000. on a percentage basis , cost of goods sold and distribution increased 30 % versus an

retroactive to january 1 , 2012. we record this credit as a reduction in cost of goods sold and distribution expense in our consolidated statement of operations . as a result of the prior year reinstatement , we recognized a $ 2,535,000 reduction to cost of goods sold in the first quarter of 2013. no such reduction existed for 2012. the existence of this credit was a significant factor in the profitability of biodiesel production in 2013. this credit expired at december 31 , 2013. 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 . biodiesel profitability slowed in the fourth quarter of 2013 as the biodiesel consumption mandate established by the government was largely met early in the quarter . during the fourth quarter of 2012 , government mandate had also been met , however , profitability slowed considerably more in the fourth quarter of 2012 due to the absence of the $ 1.00 blenders ' credit . operating expenses operating expenses decreased 13 % from $ 11,161,000 in 2012 to $ 9,911,000 in 2013. this decrease was primarily the result of reduced compensation expense from reduced staffing , reduced legal expenditures associated with litigation of ongoing cases , and reduced expenditures incurred for the registration of product for sale in the european union . provision for income taxes the effective tax rates for the years ended december 31 , 2013 and 2012 reflect our expected tax rate on reported operating earnings before income taxes . historically , we included the benefit from the $ 1 biodiesel blenders ' tax credit in taxable income on our federal and state income tax returns . as a result of recently issued technical guidance from the u.s. internal revenue service , we have changed our position related to this benefit to exclude it from taxable income for the years 2010 through the current year . this change had a significant impact on our provision for income taxes in the fourth quarter of 2013. this benefit reduced our provision for income taxes by $ 11,633,000 , with $ 7,755,000 related to the years 2010 through 2012 , and $ 3,878,000 related to the current year . this benefit is not expected to recur in the future as the $ 1 biodiesel blenders ' tax credit expired on december 31 , 2013 and has not been renewed . this change reduced taxable income in each year between 2010 and 2012 and also impacted fiscal 2013. this change is expected to result in a refund from the u.s. internal revenue service for a portion of the amount we have paid for income taxes in prior years . 41 income taxes our liability for uncertain tax positions totaled $ 1,718,000 and $ 0 at december 31 , 2013 and 2012
