, taxes and disruptions and limitations of operations , including those related to climate change and health and safety and those that could impact the company 's ability to continue or renew its operating permits ; and ( xi ) other risks and uncertainties set forth in this report or indicated from time to time in the company 's filings with the sec , including the company 's quarterly reports on form 10-q . overview . general . we have identified two business segments based on the distinctness of their activities and products : lime and limestone operations and natural gas interests . all operations are in the united states . in evaluating the operating results of our segments , management primarily reviews revenues and gross profit . we do not allocate corporate overhead or interest costs to our business segments . our lime and limestone operations represent our principal business . our natural gas interests consist of royalty and non-operating working interests under the o & g lease and the drillsite agreement with two separate operators related to our johnson county , texas property , located in the barnett shale formation , on which texas lime conducts its lime and limestone operations . our principal management decisions related to our natural gas interests involve whether to participate as a non-operating working interest owner by contributing our proportional costs for drilling proposed wells or workovers of existing wells under the o & g lease and the drillsite agreement . while we intend to continue to participate in future natural gas wells drilled and workovers of existing wells on our o & g properties , if any , we are not in the business of drilling for or producing natural gas , and have no personnel expert in that field . revenues from our lime and limestone operations decreased 2.6 % in 2013 compared to 2012. the decreased sales volumes of our lime and limestone products , which accounted for a revenue decrease of approximately 3.8 % for 2013 compared to 2012 , resulted principally from reduced sales volumes to our steel customers , partially offset by increased sales volumes to our construction and environmental customers , although we had reduced demand from our construction customers in the fourth quarter 2013 due to inclement weather conditions compared to favorable weather conditions in the fourth quarter 2012. this decrease in sales volumes was partially offset by average product price increases of approximately 1.2 % for our lime and limestone products in 2013 compared to 2012. revenues from our natural gas interests decreased $ 1.4 million , or 19.1 % , to $ 5.8 million in 2013 from $ 7.1 million in 2012 primarily due to decreased production volumes resulting from the normal declines in production rates on the company 's existing natural gas wells . the decrease in revenues from our natural gas interests in 2013 resulted from lower production volumes in 2013 ( approximately 21.2 % ) , partially offset by price increases in 2013 ( approximately 2.1 % ) . our gross profit decreased 7.9 % in 2013 compared to 2012. gross profit from our lime and limestone operations in 2013 decreased 5.4 % compared to 2012 primarily due to the decreased revenues discussed above and increased cost of revenues in the fourth quarter 2013 resulting from production inefficiencies due to the inclement weather conditions , partially offset by a reduction in our 23 stripping costs of approximately $ 0.6 million in 2013 compared to 2012. the timing and amount of our stripping costs in the future will depend upon , among other things , the availability and cost-effective utilization of contractors and their equipment and our employees and equipment , but we believe the costs of our ongoing stripping will be at approximately the same rate to production as we incurred in 2013. our gross profit from our natural gas interests decreased 26.7 % in 2013 compared to 2012 due to the decreased revenues discussed above . these decreases in gross profit resulted in a $ 1.6 million , or 9.9 % , decrease in our net income in 2013 compared to 2012. cash flows from operations during 2012 enabled us to continue to service our bank debt , make $ 8.9 million of capital investments , and leave us with cash balances of $ 49.5 million at december 31 , 2013 compared to $ 29.8 million at december 31 , 2012. our significant cash flows and strong balance sheet enabled us to declare a quarterly cash dividend to our shareholders payable on march 20 , 2014. lime and limestone operations . in our lime and limestone operations , we produce and sell pls , quicklime , hydrated lime and lime slurry . the principal factors affecting our success are the level of demand and prices for our products and whether we are able to maintain sufficient production levels and product quality while controlling costs . inclement weather conditions generally reduce the demand for lime and limestone products supplied to construction-related customers that account for a significant amount of our revenues . inclement weather also interferes with our open-pit mining operations and can disrupt our plant production , as in the case of winter ice storms and freezing weather . in addition to weather , various maintenance , environmental , accident and other operational issues can also disrupt our operations and increase our operating expenses . story_separator_special_tag interest expense in 2013 included $ 1.1 million paid in quarterly settlement payments pursuant to our interest rate hedges , compared to $ 1.3 million paid in 2012. the decrease in interest expense in 2013 resulted from decreased average outstanding debt . income tax expense decreased to $ 5.0 million for 2013 from $ 5.7 million in 2012 , a decrease of $ 645 thousand , or 11.4 % . the decrease in income tax expense in 2013 compared to 2012 was primarily due to the decrease in our income before taxes . our effective income tax rate for 2013 decreased to 25.4 % compared to our 2012 rate of 25.7 % . net income decreased by $ 1.6 million , or 9.9 % , to $ 14.8 million ( $ 2.66 per share diluted ) , compared to net income of $ 16.4 million ( $ 2.87 per share diluted ) in 2012 . 2012 vs. 2011 revenues for 2012 decreased to $ 138.5 million from $ 142.6 million in 2011 , a decrease of $ 4.1 million , or 2.8 % . revenues from our lime and limestone operations for 2012 increased $ 1.7 million , or 1.3 % , to $ 131.4 million from $ 129.7 million in 2011. the increase in revenues from our lime and limestone operations was primarily due to increased prices realized for our lime and limestone products in 2012 , compared to 2011 , partially offset by decreased sales volumes of lime and limestone products principally due to decreased demand from our steel and oil and gas services customers . revenues from our natural gas interests for 2012 decreased $ 5.8 million , or 44.7 % , to $ 7.1 million from $ 12.9 million in 2011. the decrease in revenues from our natural gas interests resulted from decreased average prices received per mcf , principally as a result of decreased prices for both natural gas and liquids contained in our natural gas , and the normal declines in production rates on existing wells . natural gas interests revenues for 2011 also included $ 487 thousand from the final favorable resolution of certain royalty ownership issues on unitized natural gas wells . our gross profit decreased to $ 33.4 million for 2012 from $ 41.3 million for 2011 , a decrease of $ 7.9 million , or 19.1 % . gross profit from our lime and limestone operations for 2012 was $ 29.5 million , compared to $ 32.1 million in 2011 , a decrease of $ 2.6 million , or 8.2 % . the decrease in gross profit in 2012 compared to 2011 resulted primarily from contractor stripping costs of $ 2.6 million incurred principally in the second and third quarters 2012 , compared to no such contractor stripping costs in 2011. gross profit for 2012 also included $ 3.9 million from our natural gas interests , compared to $ 9.2 million in 2011 , a decrease of $ 5.3 million or 57.2 % . there were 39 producing wells at both december 31 , 2012 and 2011. production volumes for 2012 from our natural gas interests totaled 1.2 bcf , sold at an average price per mcf of $ 5.74 , compared to 2011 when 1.6 bcf was produced and sold at an average price of $ 8.27 per mcf . in addition , 2011 included a $ 463 thousand contribution to gross profit from the resolution of certain royalty ownership issues . sg & a increased to $ 9.2 million for 2012 from $ 8.8 million in 2011 , an increase of $ 347 thousand , or 3.9 % . as a percentage of revenues , sg & a increased to 6.6 % in 2012 from 6.2 % in 2011. the increase in sg & a in 2012 was primarily attributable to increased non-cash stock-based compensation costs , which increased $ 204 thousand , or 29.6 % , compared to 2011 , due to increases in the price per share of the company 's common stock on the most recent grant dates , compared to the prices per share on previous grant dates . 29 interest expense in 2012 decreased to $ 2.2 million from $ 2.5 million in 2011 , a decrease of $ 332 thousand , or 13.3 % . interest expense in 2012 and 2011 included $ 1.3 million and $ 1.6 million , respectively , paid in aggregate quarterly settlement payments pursuant to our interest rate hedges . the decrease in interest expense in 2012 resulted from decreased average outstanding debt . income tax expense decreased to $ 5.7 million in 2012 from $ 8.0 million in 2011 , a decrease of $ 2.3 million , or 28.6 % . the decrease in income tax expense in 2012 compared to 2011 was primarily due to the decrease in our income before taxes . our effective income tax rate for 2012 decreased to 25.7 % compared to our 2011 rate of 26.4 % primarily because of proportionately higher statutory depletion rates as a percentage of pretax income in 2012 compared to 2011. net income decreased to $ 16.4 million ( $ 2.87 per share diluted ) in 2012 , compared to $ 22.2 million ( $ 3.49 per share diluted ) in 2011 , a decrease of $ 5.8 million , or 26.0 % . earnings per share for 2012 was favorably impacted by $ 0.32 per share by the company 's repurchase of 200,000 shares of its common stock during the third quarter 2011 and 700,000 shares of common stock in the first quarter 2012. earnings per share for 2011 was favorably impacted by $ 0.04 per share by the 2011 repurchase of 200,000 shares of common stock . financial condition . capital requirements . we require capital primarily for seasonal working capital needs , normal recurring capital and re-equipping projects , modernization and expansion and development projects , drilling , completion and working over

liquidity and capital resources . net cash provided by operations was $ 33.5 million for 2013 , compared to $ 31.7 million in 2012 , an increase of $ 1.8 million , or 5.8 % . our cash provided by operating activities is composed of net income , depreciation , depletion and amortization ( `` dd & a '' ) , other non-cash items included in net income and changes in working capital . in 2013 , cash provided by operating activities was principally composed of $ 14.8 million net income , $ 14.5 million dd & a , $ 1.7 million deferred income taxes , $ 0.9 million of stock-based compensation and $ 1.4 million from changes in operating assets and liabilities . the increase in 2013 compared to 2012 was primarily the result of the $ 0.4 million decrease in inventories in 2013 compared to a $ 3.4 million increase in 2012 , and the $ 0.6 million increase in accounts payable and accrued expenses in 2013 compared to a $ 1.1 million decrease in 2012. these increases were partially offset by the $ 1.6 million decrease in net income in 2013. net cash used in investing activities was $ 8.7 million for 2013 compared to $ 8.3 million in 2012 , primarily for normal recurring capital and re-equipping projects at our plants and facilities . net cash used in financing activities primarily consisted of $ 5.0 million to repay term loans in 2013 , compared to $ 6.25 million in 2012 , and $ 0.2 million to repurchase shares of our common stock in 2013 , compared to $ 40.8 million in 2012. our cash and cash equivalents at december 31 , 2013 increased to $ 49.5 million from $ 29.8 million at december 31 , 2012. banking facilities and other debt our credit agreement includes a ten-year $ 40 million term loan ( the `` term loan '' ) , a ten-year $ 20 million multiple draw term loan ( the `` draw term loan '' ) and a $ 30 million revolving credit facility ( the `` revolving facility '' ) ( collectively , the `` credit facilities '' ) .
