impairments the following table summarizes the impairments recorded for the periods presented : replace_table_token_29_th during 2011 , we recognized an impairment of our arkoma basin assets for $ 71.1 million , which was triggered by the expected disposition of these high-cost gas properties . as described in note 3 , we completed the sale of these properties in august 2011. also during 2011 , we recognized an impairment of our horizontal coal bed methane properties in the appalachian region for $ 26.6 million and certain dry-gas properties in mississippi for $ 7.0 million due primarily to market declines in gas prices . during 2010 , we incurred impairment charges related to our mid-continent coal bed methane properties as a result of market declines in gas prices and to an area in the anadarko basin of the mid-continent region where we drilled an uneconomic well . in addition , we recorded impairment charges attributable to certain oil and gas inventory assets triggered primarily by declines in asset quality . 31 other during 2011 , we recorded a reserve of $ 0.2 million for litigation attributable to properties that were previously sold . this matter was ultimately settled in january 2012 for the reserved amount . in addition , we wrote down certain gas imbalance assets that originated in prior years due to lower settlement rates . during 2010 , we recorded a loss on the disposition of our gulf coast properties . interest expense the following table summarizes the components of our interest expense for the periods presented : replace_table_token_30_th the issuance of the 2019 senior notes at 7.25 % and borrowings under the revolver , offset by the repurchase of approximately 98 % of the outstanding convertible notes with an effective interest rate of 8.5 % , resulted in an approximate $ 88 million higher weighted-average balance of debt outstanding during 2011 as compared to 2010. accordingly , interest expense increased due to the higher average outstanding principal balance partially offset by lower effective interest rates attributable to the 2019 senior notes and revolver . capitalized interest was higher during 2011 due to higher carrying values on eligible capital projects . loss on extinguishment of debt the repurchase in april 2011 of approximately 98 % of the outstanding convertible notes resulted in a loss on extinguishment of debt of $ 24.2 million . the loss was comprised of non-cash charges for the excess of cash paid for the liability component over the carrying value , plus the write-off of a pro rata share of debt issuance costs and incremental transaction fees paid in cash . in addition , we recognized a charge of $ 1.2 million in august 2011 attributable to the revolver and a change in the composition of the bank syndicate . derivatives the following table summarizes the components of our derivatives income for the periods presented : replace_table_token_31_th we received cash settlements of $ 27.4 million during 2011 and $ 32.8 million during 2010. the amount received during 2011 includes $ 2.9 million attributable to the termination of our interest rate swap . other other income decreased due primarily to lower interest income earned on average cash balances during 2011 and gains on the sale of non-operating investments recognized during 2010. income taxes the effective tax benefit rate for continuing operations during 2011 was 39.9 % compared to 39.6 % for 2010. due to the operating losses incurred , we recognized an income tax benefit during both periods . in addition , the effective tax rate for 2011 includes a deferred tax asset valuation allowance due primarily to the inability to recognize a tax benefit for certain state net operating losses . 32 year ended december

replace_table_token_34_th replace_table_token_35_th replace_table_token_36_th the decline in production during 2010 was attributable to the disposition of our gulf coast properties in january 2010 , the significant reduction in drilling activity in 2009 and natural declines in production rates . we also experienced equipment and service-related delays in new well completions during the first half of 2010 primarily in the lower bossier ( haynesville ) shale play in the texas region . the overall decline in production volume was partially offset by production from new wells in the granite wash play in the mid-continent region that were brought online during 2010 despite interference attributable to offset wells during stimulation . ngl production increased to 18 % of the total production in 2010 compared to 15 % in 2009. in addition , a processing agreement was signed for a major portion of our granite wash production which contributed to the increase in 2010 ngl production . 34 product

replace_table_token_38_th replace_table_token_39_th replace_table_token_40_th 35 as illustrated below , revenues were higher in 2010 compared to 2009 as the decline in production volume discussed above was more than offset by improved pricing for all three commodity product types . the following table provides an analysis of the change in our revenues for the year ended december 31 , 2010 as compared to the year ended december 31 , 2009 : replace_table_token_41_th effects of derivatives in 2010 and 2009 , we received $ 33.5 million and $ 59.9 million in cash settlements of oil and gas derivatives . story_separator_special_tag in addition , 2009 included a reclassification of expense from accumulated other comprehensive income , or aoci , attributable to the discontinuation of hedge accounting related to our interest rate swaps , as well as a reversal of interest cost attributable to the settlement of various state income tax positions . derivatives the following table summarizes the components of our derivatives income for the periods presented : replace_table_token_49_th cash received for settlements during 2010 was $ 32.8 million as compared to $ 58.1 million during 2009. other other income increased during 2010 due primarily to the gains on the sale of non-operating investments as well as higher interest income on the significantly larger cash balances held following of the disposition of our interests in pvg . income taxes the effective tax benefit rate for continuing operations was 39.6 % for 2010 and 2009. due to the operating losses incurred , we recognized an income tax benefit during both periods . discontinued operations the following table presents a summary of results of operations from discontinued operations for the periods presented : replace_table_token_50_th 1 determined by applying the effective tax rate attributable to discontinued operations to the income from discontinued operations less noncontrolling interests that are fully attributable to pvg 's operations . the disclosures for 2010 provided in the table above reflect the results of operations of pvg through the date of disposition of our entire remaining interest in pvg on june 7 , 2010 . 39 gain on sale of discontinued operations the following table summarizes the determination of the gain recognized upon the disposition of pvg : cash proceeds , net of offering costs ( 8,827,429 units x $ 15.76 per unit ) $ 139,120 carrying value of noncontrolling interests in pvg at date of disposition 382,324 521,444 less : carrying value of pvg 's assets and liabilities at date of disposition ( 434,782 ) 86,662 less : income tax expense ( 35,116 ) gain on sale of discontinued operations , net of tax $ 51,546 noncontrolling interests the decrease in net income attributable to noncontrolling interests during 2010 is directly attributable to the sale of our interests in pvg during june 2010. in september 2009 , our ownership interest in pvg declined from 77.0 % to 51.4 % and in 2010 our ownership interest in pvg declined to zero . 40 liquidity and capital resources sources of liquidity we are currently meeting our capital expenditures and working capital funding requirements with a combination of operating cash flows and borrowings from our revolver . we have no material debt maturities until 2016. our business strategy for 2012 requires capital expenditures in excess of our anticipated operating cash flows . subject to the variability of commodity prices that impact our operating cash flows , anticipated timing of our capital projects and unanticipated expenditures such as acquisitions , we plan to fund our 2012 capital program with operating cash flows and borrowings from our revolver . we expect to supplement these sources of liquidity with proceeds from the sale of non-core assets or , possibly , by accessing the capital markets . there can be no assurance that such actions would be successful , however , in which case we could reduce our 2012 planned capital expenditures . in august 2011 , we entered into the revolver which matures in august 2016. the revolver provides for a $ 300 million revolving commitment , including a $ 20 million sublimit for the issuance of letters of credit . the revolver has a borrowing base of $ 380 million . there is an accordion feature that allows us to increase the commitment up to the lower of the borrowing base or $ 600 million upon receiving additional commitments from one or more lenders . the revolver is available to us for general purposes including working capital , capital expenditures and acquisitions . the borrowing base is redetermined semi-annually , and the next redetermination is scheduled to occur during april 2012. the primary assets supporting our borrowing base are our proved developed reserves , approximately 77 % of which are natural gas . due primarily to the significant decline in natural gas prices that has continued into the first quarter of 2012 and despite the increase in our oil reserves , we anticipate a potentially material reduction in our borrowing base from its current level of $ 380 million . as of the date of this filing , we are unable to determine a meaningful potential range of the reduction , due primarily to the fact that a number of determinative variables are not known at this time ; however , we do not anticipate a material reduction to our current revolver commitment of $ 300 million . accordingly , our current business plans anticipate us borrowing amounts under the revolver that are within the current commitment level of $ 300 million . as of february 21 , 2012 , we had approximately $ 11 million of cash on hand and $ 182.6 million of unused borrowing capacity under our revolver . the borrowing capacity is determined by reducing the revolving commitment of $ 300 million by outstanding borrowings of $ 116.0 million and outstanding letters of credit of $ 1.4 million . the following table summarizes our borrowing activity under the revolver during the periods presented : replace_table_token_51_th 1 there were no amounts outstanding under the previous credit facility from january 1 , 2011 through its termination date of august 2 , 2011. our revenues are subject to significant volatility as a result of changes in commodity prices . accordingly , we actively manage the exposure of our operating cash flows to commodity price fluctuations by hedging the commodity price risk for a portion of our expected production through the use of derivatives , typically collar , swap and swaption contracts . the level of our hedging activity and duration of the instruments employed depend upon our cash flow at risk , available

cash flows from financing activities cash provided by financing activities during 2011 included the issuance of $ 300 million of 2019 senior notes , offset substantially by the repurchase of approximately 98 % of our convertible notes and related transaction costs . during the third quarter of 2011 , we began borrowing under our revolver . in addition , we paid dividends totaling $ 10.3 million on our common stock . during april 2010 , we sold 11.25 million common units of pvg for proceeds of $ 199.1 million , net of offering costs , which reduced our limited partner interest in pvg to 22.6 % . because we maintained a controlling financial interest in pvg until the final sale , the proceeds from these transactions are reported as cash flows from financing activities . in addition , we received $ 11.2 million in distributions from pvg prior to our complete divestiture in 2010 as well as $ 2.1 million from the exercise of stock options by employees . we also paid dividends totaling $ 10.3 million on our common stock . 43 financial condition as of february 21 , 2012 , we had approximately $ 11 million of cash on hand and $ 182.6 million of unused borrowing capacity under our revolver . the borrowing capacity is determined by reducing the revolving commitment of $ 300 million by outstanding borrowings of $ 116.0 million and outstanding letters of credit of $ 1.4 million . debt and credit facilities replace_table_token_55_th revolving credit facility .
