these declines were the result of overall softness in freight within the truckload segment , resulting in a slight decline in miles per tractor per week and a 3.9 % decrease in the average tractor count , even considering a 5.3 % increase in the number of team tractors , and average rates per total mile declining 2.2 cents per mile . cost in the truckload segment increased 8.3 cents per mile , primarily as a result of increased capital cost , resulting from the significant decline in used equipment values and related increase in depreciation . on the contrary , our non-truckload operations experienced growth in both revenue and profitability as we were able to take advantage of the market dynamics and realize the full year effect of several business model changes and new customers added in 2015. our consolidated financial results are summarized as follows : ● total revenue was $ 670.7 million , compared with $ 724.2 million for 2015 , and freight revenue ( excludes revenue from fuel surcharge ) was $ 610.8 million , compared with $ 640.1 million for 2015 ; ● operating income was $ 32.4 million , compared with operating income of $ 67.8 million for 2015 ; 36 ● net income was $ 16.8 million , or $ 0.92 per diluted share , compared with net income of $ 42.1 million , or $ 2.30 per diluted share , for 2015. net income for 2015 includes a one-time federal income tax credit of approximately $ 4.7 million , or $ 0.26 per diluted share and an insurance policy commutation credit of approximately $ 2.2 million , or $ 0.12 per diluted share ; ● our equity investment in tel provided $ 3.0 million of pre-tax earnings in 2016 compared to $ 4.6 million for 2015 ; and ● stockholders ' equity and tangible book value at december 31 , 2016 , were $ 236.4 million , or $ 12.95 per basic share . although 2016 was not what we had hoped , we are still encouraged by the trend line over the last several years . our turnaround efforts at srt were fully engaged in 2016 , including a new management team , and we have established a roadmap that we believe will be successful in returning srt 's results to levels where they produce an acceptable return . we continue to focus on deleveraging the balance sheet resulting in total indebtedness , net of cash and including the present value of off-balance sheet lease obligations decreasing by approximately $ 37.5 million to $ 226.7 million , since december 31 , 2015. additionally , earnings and the reduced impact of fuel hedges have increased tangible book value per basic share 16.1 % to $ 12.95 from $ 11.15 at december 31 , 2015. in addition to operating ratio , we use `` adjusted operating ratio `` as a key measure of profitability . adjusted operating ratio is not a substitute for operating ratio measured in accordance with gaap . there are limitations to using non-gaap financial measures . adjusted operating ratio means operating expenses , net of fuel surcharge revenue , expressed as a percentage of revenue , excluding fuel surcharge revenue . we believe the use of adjusted operating ratio allows us to more effectively compare periods , while excluding the potentially volatile effect of changes in fuel prices . our board and management focus on our adjusted operating ratio as an indicator of our performance from period to period . we believe our presentation of adjusted operating ratio is useful because it provides investors and securities analysts the same information that we use internally to assess our core operating performance . although we believe that adjusted operating ratio improves comparability in analyzing our period-to-period performance , it could limit comparability to other companies in our industry , if those companies define adjusted operating ratio differently . because of these limitations , adjusted operating ratio should not be considered a measure of income generated by our business or discretionary cash available to us to invest in the growth of our business . management compensates for these limitations by primarily relying on gaap results and using non-gaap financial measures on a supplemental basis . operating ratio replace_table_token_6_th 37 outlook we are forecasting sequential improvement for 2017. in the first half of 2017 we do not expect to match the earnings per share levels we generated for the first and second quarters of 2016. however , we believe the combination of an improving economy , growth of time-sensitive e-commerce freight , industry regulatory changes , retail inventory declines , year-over-year net fuel expense savings from our improved fuel hedge positions , and operational progress at srt should deliver earnings improvement that result in higher earnings for the second half and potentially the full year of 2017. the largest variable we foresee is the pace and magnitude of improvement at srt , which we believe could contribute up to $ 10.0 million of pre-tax income in improved results as compared with 2016. the pace and amount of change will depend , in large part , on our ability to enhance the freight network , which depends on internally re-engineering lanes and a stronger refrigerated freight market . with net capital expenditures scheduled to be below normal due to the timing of our expected replacement cycle , along with anticipated positive operating cash flows , we expect to further reduce balance sheet and off-balance sheet debt over the course of fiscal 2017. our 2017 plans also include growing our dedicated service line and investing in personnel and trailer tracking equipment that will allow more cross-border freight opportunities . story_separator_special_tag for the year ended december 31 , 2015 , operations and maintenance decreased $ 0.8 million , or 1.7 % , compared with 2014. as a percentage of total revenue , operations and maintenance remained relatively even at 6.4 % of total revenue in 2015 , compared with 6.6 % in 2014. as a percentage of freight revenue , operations and maintenance decreased to 7.3 % of freight revenue for 2015 , from 8.2 % in 2014 due to a decrease in our average age of equipment partially offset by increased driver recruiting costs . 41 going forward , we believe this category will fluctuate based on several factors , including our continued ability to maintain a relatively young fleet , accident severity and frequency , weather , and the reliability of new and untested revenue equipment models . revenue equipment rentals and purchased transportation replace_table_token_12_th revenue equipment rentals and purchased transportation decreased approximately $ 1.1 million , or 0.9 % , for the year ended december 31 , 2016 , compared with 2015. as a percentage of total revenue , revenue equipment rentals and purchased transportation increased to 17.5 % of total revenue for the year ended december 31 , 2016 , from 16.4 % in 2015. as a percentage of freight revenue , revenue equipment rentals and purchased transportation increased to 19.2 % of freight revenue for the year ended december 31 , 2016 , from 18.5 % in 2015. these changes were primarily the result of a $ 0.7 million increase in payments to third-party transportation providers related to increased revenues at our solutions subsidiary and growth of our temperature-controlled intermodal service offering . these increases were partially offset by a decrease in leased equipment rental payments due to a reduction in our trailers under operating leases from 2,239 at december 31 , 2105 to 1,695 at december 31 , 2016. for the year ended december 31 , 2015 , revenue equipment rentals and purchased transportation increased approximately $ 6.8 million , or 6.1 % , for the year ended december 31 , 2015 , compared with 2014. as a percentage of total revenue , revenue equipment rentals and purchased transportation increased to 16.4 % of total revenue for the year ended december 31 , 2015 , from 15.5 % in 2014. as a percentage of freight revenue , revenue equipment rentals and purchased transportation decreased to 18.5 % of freight revenue for the year ended december 31 , 2015 , from 19.3 % in 2014. these changes were primarily the result of a $ 14.4 million increase in payments to third-party transportation providers related to increased revenues at our solutions subsidiary , growth of our temperature-controlled intermodal service offering and an increase in payments to independent contractors , which comprised a larger percentage of our total fleet . these increases were partially offset by a decrease in leased equipment rental payments and by lower fuel surcharge pass-through payments to independent contractors and third party carriers . for the year ended december 31 , 2015 , miles run by independent contractors increased to 9.0 % of our total miles from 8.2 % for 2014 , and tractors under operating leases decreased to 115 units from 150 units in 2014. we expect revenue equipment rentals to decrease going forward as a result of our increase in acquisition of revenue equipment through financed purchases or capital leases rather than operating leases . as discussed below , this decrease may be partially or fully offset by an increase in purchased transportation as we expect to continue to grow our solutions and intermodal service offerings . we expect purchased transportation to increase as we seek to grow our solutions subsidiary and if fuel prices continue to increase , which would result in an increase in what we pay third party carriers and independent contractors . however , this expense category will fluctuate with the number and percentage of loads hauled by independent contractors , loads handled by solutions , and tractors , trailers , and other assets financed with operating leases . in addition , factors such as the cost to obtain third party transportation services , and growth of our intermodal service offerings , and the amount of fuel surcharge revenue passed through to the third party carriers and independent contractors will affect this expense category . if industry-wide trucking capacity were to tighten in relation to freight demand , we may need to increase the amounts we pay to third-party transportation providers , independent contractors , and intermodal transportation providers , which could increase this expense category on an absolute basis and as a percentage of freight revenue absent an offsetting increase in revenue . we continue to actively recruit independent contractors and , if we are successful , we would expect this line item to increase as a percentage of revenue . operating taxes and licenses replace_table_token_13_th for the periods presented , the change in operating taxes and licenses was not significant as either a percentage of total revenue or freight revenue . 42 insurance and claims replace_table_token_14_th insurance and claims , consisting primarily of premiums and deductible amounts for liability , physical damage , and cargo damage insurance and claims , increased approximately $ 0.7 million , or 2.2 % , for year ended december 31 , 2016 , compared to 2015. as a percentage of total revenue , insurance and claims increased to 4.9 % of total revenue for the year ended december 31 , 2016 , from 4.4 % in 2015. as a percentage of freight revenue , insurance and claims increased to 5.3 % of freight revenue for the year ended december 31 , 2016 , from 5.0 % in 2015. these increases are primarily related to the non-recurring $ 3.6 million benefit in the second quarter of 2015 from commutation of our auto liability policy for the period from april 1 , 2013 , through september 30 , 2014. these increases also resulted

cash flows net cash flows provided by operating activities were $ 102.4 million in 2016 compared with $ 85.5 million in 2015 primarily due to the change in receivables and advances as a result of increased cash collected during 2016 related to increased 2015 year-end revenues , and the fluctuation in tax benefit/expense due to the reversal of deferred tax effects on amounts in other comprehensive income . this improvement is partially offset by net income of $ 16.8 million in 2016 compared to net income of $ 42.1 million in 2015 , depreciation and amortization increasing $ 9.6 million in 2016 , primarily as the result of the reduced residual revenue equipment value projections due to the softened used equipment market and the 2015 purchase of our previously leased chattanooga headquarters property , and the 2015 return of $ 5.0 million which was previously provided by us to certain of our derivative counterparties related to the net liability position of certain of our fuel derivative instruments . the fluctuations in cash flows from accounts payable and accrued expenses primarily related to the timing of payments on our accrued expenses and trade accounts in the 2016 period compared to the 2015 period . 47 net cash flows used by investing activities were $ 47.3 million in 2016 compared with $ 147.7 million in 2015. the $ 100.4 million decrease in net investing activities was attributable primarily to the purchase of our corporate headquarters property in chattanooga , tennessee during 2015 for approximately $ 35.5 million , as well as a $ 22.9 million decrease in assets held for sale due to the timing of dispositions of used revenue equipment . during 2017 we plan to take delivery of approximately 485 new company tractors and dispose of approximately 460 used tractors . this compares to the approximately 650 new company tractors we took delivery of and the approximately 1,074 used tractors we disposed of during 2016 , including 365 recorded as assets held for sale at december 31 , 2015. going forward , cash flows from disposals of equipment could be more volatile given the weakness in the used tractor market .
