the second group is made up of geokinetics , global geophysical services , inc. , or global geophysical , tesla exploration , ltd. , or tesla , breckenridge geophysical inc. , or breckenridge , paragon geophysical services , inc. , or paragon , lonestar geophysical surveys , or lonestar , and smaller companies which generally run one or two seismic crews and often specialize in specific regions or types of operations . 18 we provide our seismic data acquisition services primarily to onshore oil and natural gas exploration and development companies for use in the onshore drilling and production of oil and natural gas in the continental united states and canada . the main factors influencing demand for seismic data acquisition services in our industry are the level of drilling activity by oil and natural gas companies and the sizes of such companies ' exploration and development budgets , which , in turn , depend largely on current and anticipated future crude oil and natural gas prices and depletion rates . our customers are major and independent oil and natural gas exploration and development companies . the services we provide to our customers vary according to the size and needs of each customer . our services are marketed by supervisory and executive personnel who contact customers to determine their needs and respond to customer inquiries regarding the availability of crews . contacts are based principally upon professional relationships developed over a number of years . the acquisition of seismic data for the oil and natural gas industry is a highly competitive business . contracts for such services generally are awarded on the basis of price quotations , crew experience , and the availability of crews to perform in a timely manner , although factors other than price , such as crew safety , performance history , and technological and operational expertise , are often determinative . our competition includes publicly traded competitors , such as cgg ( which recently sold its north american onshore seismic contract acquisition business to geokinetics ) and sae . our other major competitors include geokinetics , global geophysical , tesla , breckenridge , paragon and lonestar . in addition to these previously named companies , we also compete for projects from time to time with smaller seismic companies which operate in local markets with only one or two crews . results of operations year ended december 31 , 2014 , compared to year ended december 31 , 2013 revenues . our revenues were $ 118,847,754 for the year ended december 31 , 2014 , compared to $ 134,534,540 for the same period of 2013 , a decrease of 11.7 % . this decrease was primarily due to the softening in the seismic market that began in early 2013 , our operation of fewer crews in the united states and canada during the twelve months ended december 31 , 2014 compared to the same period of 2013 , and the adverse winter weather conditions in parts of the united states and canada during the first quarter of 2014. we operated four crews in the united states during the first and second quarters of 2014 , added one crew during the third quarter ended september 30 , 2014 , and idled two crews during the fourth quarter , ending the quarter with three crews in the united states for the quarter ended december 31 , 2014. in canada , we operated six crews for most of this year 's first quarter and ended the first quarter with four crews . by late-april , all canadian crews had been shut down following the end of the winter season . we added one crew in canada in the beginning of june for summer work , but that crew worked intermittently during the third quarter . during the fourth quarter we added crews in canada for the winter season , ending the quarter with five crews . this compares with our operation of nine crews in the united states and six crews in canada during the first quarter of 2013. we began the second quarter of 2013 with eight crews operating in the united states and ended the quarter with two crews , and began the third quarter of 2013 with three crews operating in the united states and ended the quarter with five crews . in canada , we began the second quarter of 2013 operating six crews and ended the quarter operating two crews . in the third quarter of 2013 , we operated three crews in canada for short term work at the beginning of the quarter but had no crews operating in canada by the end of the quarter . we started and ended the fourth quarter of 2013 operating three crews in canada . cost of services . our cost of services was $ 101,582,377 for the year ended december 31 , 2014 , compared to $ 107,675,356 for the same period of 2013 , a decrease of 5.7 % . as a percentage of revenues , cost of services was 85.5 % for the year ended december 31 , 2014 , compared to 80.0 % for the same period of 2013. this decrease in cost of services was primarily attributable to our operation of fewer crews in the united states and canada as discussed above . the decrease was partially offset by costs incurred due to adverse winter weather conditions in parts of the united states and canada during the first quarter of this year and an increase in shot-hole work , which carries higher costs and lower margins than vibroseis work , in the united states during the third quarter . selling , general , and administrative expenses . sg & a expenses were $ 11,660,137 for the year ended december 31 , 2014 , compared to $ 9,593,068 for the same period of 2013 , an increase of 21.5 % . story_separator_special_tag 24 business combinations we allocate the purchase price of acquired companies to the tangible assets acquired , liabilities assumed , and intangible assets acquired , based on their estimated fair values . the excess of the purchase price over these fair values is recorded as goodwill . we engage independent third-party appraisal firms to assist us in determining the fair values of assets acquired and liabilities assumed . such valuations require management to make significant estimates and assumptions . allowance for doubtful accounts we prepare our allowance for doubtful accounts receivable based on our past experience of historical write-offs , our current customer base , and our review of past due accounts . the inherent volatility of the energy industry 's business cycle can cause swift and unpredictable changes in the financial stability of our customers . in 2014 , an allowance of $ 557,867 was deemed necessary . in 2013 , and 2012 , no allowances were necessary . impairment of long-lived assets we review long-lived assets for impairment when triggering events occur suggesting deterioration in the assets ' recoverability or fair value . recognition of an impairment charge is required if future expected net cash flows are insufficient to recover the carrying value of the asset . our forecast of future cash flows used to perform impairment analysis includes estimates of future revenues and profitability based on our historical results and analysis of future oil and natural gas prices which are fundamental to assessing demand for our services . if we are unable to achieve these cash flows , our estimates will be revised which could result in an impairment charge for the period of revision . depreciable lives of property , plant , and equipment our property , plant , and equipment are capitalized at historical cost and depreciated over the useful life of the asset . our estimate of this useful life is based on circumstances that exist in the seismic industry and information available at the time of the purchase of the asset . the technology of the equipment used to gather data in the seismic industry has historically evolved such that obsolescence does not occur quickly . as circumstances change and new information becomes available , these estimates could change . we amortize these capitalized items using the straight-line method . capital assets are depreciated over their useful lives ranging from one to seven years , depending on the classification of the asset . tax accounting we account for our income taxes in accordance with the recognition of amounts of taxes payable or refundable for the current year and an asset and liability approach in recognizing the amount of deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our financial statements or tax returns . we determine deferred taxes by identifying the types and amounts of existing temporary differences , measuring the total deferred tax asset or liability using the applicable tax rate , and reducing the deferred tax asset by a valuation allowance if , based on available evidence , it is more likely than not that some portion or all of the deferred tax assets will not be realized . our methodology for recording income taxes requires judgment regarding assumptions and the use of estimates , including determining our annual effective tax rate and the valuation of deferred tax assets , which can create a variance between actual results and estimates and could have a material impact on our provision or benefit for income taxes . share-based compensation we recognize the fair value of the stock-based compensation awards , including stock options and restricted stock , as wages in the consolidated statements of earnings on a straight-line basis over the vesting period of the related stock options or restricted stock awards . this has resulted in the recognition of compensation expense , relative to stock-based awards , in wages in the consolidated statements of earnings of approximately $ 689,000 or approximately $ 0.09 per share for the year ended december 31 , 2014 , and $ 973,000 or approximately $ 0.13 per share for the year ended december 31 , 2013 . 25 shares of restricted stock were issued to employees of the company under the 2006 stock awards plan as follows : 6,000 in august of 2007 ; 3,333 in june of 2008 ; 1,666 in july of 2009 ; 1,666 in may of 2010 ; 8,443 in november of 2011 ; 7,173 in december of 2011 ; 2,000 in january of 2012 ; 71,041 in august of 2012 ; 2,000 in february of 2013 , and 5,000 shares in january 2014. in june of 2013 , 15,000 shares were rescinded from the august 2012 grant , and 10,000 shares were issued in their place . in addition , stock options were issued to employees of the company under the 2006 stock awards plan as follows : 111,666 in october of 2008 ; 45,000 in november of 2009 ; 5,000 in november of 2011 , and 118,333 in july of 2014. no incentive stock options were granted to employees in 2010 , 2012 , or 2013. as of december 31 , 2014 , there was approximately $ 353,000 of unrecognized compensation expense related to our share-based compensation plan . recently issued accounting pronouncements in july 2013 , the financial accounting standards board ( fasb ) issued accounting standards update ( asu ) no . 2013-11 , income taxes ( topic 740 ) - presentation of an unrecognized tax benefit when a net operating loss carryforward , a
