the tax adjustments resulted in a net decrease to income tax expense of approximately $ 0.9 million in 2013 and zero in 2012. the tax adjustments in 2011 resulted in a reduction to the carrying value of goodwill totaling approximately $ 4.0 million due to a calculation error in the original purchase price allocation and subsequent performance of step 2 of our annual goodwill impairment analysis related to deferred income taxes and thus , ( i ) reduced deferred income taxes by approximately $ 2.7 million and ( ii ) generated a pre-tax goodwill impairment charge of approximately $ 1.4 million . further , the tax adjustments in 2011 reduced deferred tax assets by approximately $ 1.6 million that were established as a result of shared-based compensation expenses recorded previously and should have been reduced as the tax deductions were utilized . moreover , the restated amounts include previously identified and disclosed immaterial adjustments . the amounts in this item 7 of this annual report on form 10-k are reflective of the restatement which includes previously identified and disclosed immaterial adjustments . see note 2 to our consolidated financial statements included in

overview ducommun incorporated ( “ ducommun , ” “ the company , ” “ we , ” “ us ” or “ our ” ) is a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace , defense , industrial , natural resources , medical and other industries . we differentiate ourselves as a full-service solution-based provider , offering a wide range of value-added products and services in our primary businesses of electronics , structures and integrated solutions . we operate through two primary business units : ducommun labarge technologies ( “ dlt ” ) and ducommun aerostructures ( “ das ” ) . during 2014 , we made significant progress in our plan to de-lever the balance sheet , reduce interest expense and further our ability to refinance our debt in 2015. while 2014 saw growth in our commercial aerospace and industrial revenue , it was 26 partially offset by the continued weakness in defense revenue . revenue and backlog for our commercial aerospace business remains strong , reflecting increased build rates . highlights for the year ended december 31 , 2014 were as follows : 2014 net revenues were approximately $ 742.0 million net income was approximately $ 19.9 million , or $ 1.79 per diluted share cash generated from operating activities was approximately $ 53.4 million we made voluntary principal prepayments in aggregate of approximately $ 42.6 million on the term loan for the year ended december 31 , 2014 , ebitda and adjusted ebitda was approximately $ 83.3 million . see non-gaap financial measures below for certain information regarding ebitda and adjusted ebitda , including reconciliations of ebitda and adjusted ebitda to net income . non-gaap financial measures when viewed with our financial results prepared in accordance with accounting principles generally accepted in the united states of america ( “ gaap ” ) and accompanying reconciliations , we believe ebitda and adjusted ebitda provide additional useful information to clarify and enhance the understanding of the factors and trends affecting our past performance and future prospects . we define these measures , explain how they are calculated and provide reconciliations of these measures to the most comparable gaap measure in the tables below . ebitda , adjusted ebitda and the related financial ratios , as presented in this annual report on form 10-k ( “ form 10-k ” ) , are supplemental measures of our performance that are not required by , or presented in accordance with , gaap . they are not a measurement of our financial performance under gaap and should not be considered as alternatives to net income or any other performance measures derived in accordance with gaap , or as an alternative to net cash provided by operating activities as measures of our liquidity . the presentation of these measures should not be interpreted to mean that our future results will be unaffected by unusual or nonrecurring items . we use ebitda and adjusted ebitda non-gaap operating performance measures internally as complementary financial measures to evaluate the performance and trends of our businesses . we present ebitda , adjusted ebitda and the related financial ratios , as applicable , because we believe that measures such as these provide useful information with respect to our ability to meet our future debt service , capital expenditures , working capital requirements and overall operating performance . ebitda and adjusted ebitda have limitations as analytical tools , and you should not consider them in isolation or as substitutes for analysis of our results as reported under gaap . some of these limitations are : they do not reflect our cash expenditures , future requirements for capital expenditures or contractual commitments ; they do not reflect changes in , or cash requirements for , our working capital needs ; they do not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on our debt ; although depreciation and amortization are non-cash charges , the assets being depreciated and amortized will often have to be replaced in the future , and ebitda and adjusted ebitda do not reflect any cash requirements for such replacements ; they are not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows ; they do not reflect the impact on earnings of charges resulting from matters unrelated to our ongoing operations ; and other companies in our industry may calculate ebitda and adjusted ebitda differently from us , limiting their usefulness as comparative measures . story_separator_special_tag
