subsequent to the close of 2015 , nobelclad was awarded a $ 6.3 million order for specialized explosion clad plates to be used in the fabrication of equipment for a semiconductor material production facility in east asia . the order will be reflected in nobelclad 's first-quarter order backlog , and is expected to ship during the second quarter . the plates will be manufactured at nobelclad 's plant in liebenscheid , germany , which is close to the metal suppliers . 27 despite low oil prices and decreased well-completion activities in and outside of north america , we were able to increase dynaenergetics ' customer penetration in the perforating market in 2015. unit sales of dynaselect continued to grow during 2015 , as an increasing number of operators and service providers are leveraging the reliability , efficiency and safety of this industry-leading product . in the third quarter of 2015 , dynaenergetics completed field trials of its factory-assembled dynastage perforating system and entered into a principal partner agreement with weatherford international , our primary testing partner and one of the world 's largest oilfield services companies . weatherford became the first oilfield service company to deploy our dynastage product , a factory-assembled , performance-assured well perforating system incorporating the safety features of our advanced detonator technologies . we expect that our efforts to educate end users about dynastage 's efficiency and safety benefits will lead to increased sales growth and market penetration in the future . in january 2016 , dynaenergetics obtained all the permits necessary to manufacture industrial explosives at its new shaped charge plant in tyumen , siberia . test runs of the manufacturing line will commence in march 2016 , and after passing internal quality checks , the charges will be tested in several russian oil fields to ensure real-world performance . this process should be complete by the middle of the second quarter , at which point we expect to begin supplying the russian oil and gas market with high-performance charges and guns . during the fourth quarter of 2015 , to alleviate the risk that the slowdown in our core energy markets and the near-term financial impact our restructuring programs put on our leverage and debt-service-coverage ratios , we negotiated an amended credit agreement , which increases those ratios and grants us additional financial flexibility for the coming year . restructuring during 2015 , we executed several programs to enhance operating efficiencies across our businesses , including closing distribution and production centers , consolidating manufacturing to more cost-effective locations , and reducing corporate headcount . the total restructuring charges for 2015 and 2014 were $ 4,063 and $ 6,781 , respectively . in the first quarter of 2015 , we launched several initiatives to enhance dynaenergetics ' operational efficiencies and align its production and distribution resources with the anticipated demands of the market . in january 2015 , we closed two north american distribution centers . on february 24 , 2015 , we announced the closure of a perforating gun manufacturing facility and distribution center in edmonton , alberta . in the second quarter of 2015 , we consolidated north america perforating gun manufacturing into dynaenergetics ' existing facility in whitney , texas . we also exited multiple other distribution centers in north america and colombia . the colombia market is now being served directly from our existing facilities in texas . two new centralized distribution centers replaced the smaller and less efficient distribution centers that were closed . in the first quarter of 2015 , we eliminated certain positions in our corporate office . additionally , two of the nine members of our board of directors did not stand for re-election at our annual meeting in may 2015. in the second quarter of 2015 , as part of a plan announced in october 2014 , the majority of european clad metal plate production was shifted from facilities in both rivesaltes , france and würgendorf , germany to the new manufacturing facility in liebenscheid , germany . nobelclad 's rivesaltes plant will continue to produce transition joints with a reduced workforce while the würgendorf site was closed and its workers were transferred to the new facility . in the fourth quarter of 2015 , we took additional measures as part of our continuing efforts to control costs in a challenging market . in dynaenergetics , we implemented a short work week in troisdorf , germany , eliminated production shifts at both of its u.s. manufacturing sites and closed two additional u.s. distribution centers . on october 20 , 2015 , we announced a reduction in force ( `` rif `` ) affecting 12 employees at dynaenergetics ' corporate offices in troisdorf , germany . we incurred severance charges of $ 486 related to this restructuring . goodwill impairment as discussed below in `` critical accounting policies and estimates `` , we perform our goodwill impairment test annually as of december 31 , 2015 or when indicators of impairment exist . for 2015 , we found that the fair value of the dynaenergetics reporting unit was less than its carrying value by approximately 14 % due primarily to the sustained decline in global oil prices , expected reduction in exploration and production activities of certain of our customers , and the impact these factors have on our expected future cash flows . we valued the assets of dynaenergetics and , based on the results of that valuation , recorded a goodwill impairment charge of $ 11,464 . there was no impairment of goodwill for the nobelclad reporting unit for the year 28 ended december 31 , 2015. as of december 31 , 2015 , the fair value of the nobelclad reporting unit , with $ 17,190 of goodwill , exceeded the carrying value of its net assets by approximately 19 % . story_separator_special_tag reflects lower average outstanding borrowings in the first quarter of 2014 as interest rates remained relatively stable . income tax provision we recorded an income tax provision of $ 3,913 in 2014 compared with $ 3,736 in 2013. our 2014 effective tax rate of 67 % includes valuation allowances of $ 3,737 recorded in the second half of 2014 as described below , partially offset by favorable changes in tax law of $ 1,376. our 2013 effective tax rate was 38.1 % . our consolidated income tax provision for 2014 and 2013 included $ 1,098 and $ 810 , respectively , related to u.s. taxes , with the remainder relating to net foreign tax provisions of $ 2,815 in 2014 and $ 2,926 in 2013 , respectively , associated with our foreign operations and holding companies . discontinued operations on october 1 , 2014 we completed the sale of our amk business . the net proceeds were $ 6,830 , after final purchase price adjustments , and and the purchase was financed through $ 4,330 in cash consideration and the issuance of a $ 2,500 90-day secured promissory note to the company which was paid in full by december 31 , 2014. the excess of the selling price over the carrying value of $ 1,476 was recorded in our statement of operations in the fourth quarter 2014. amk 's net sales were $ 4,540 and $ 7,513 in 2014 and 2013 , respectively . amk had a loss from discontinued operations of $ 77 , net of tax of $ 1 for 2014 compared to income from discontinued operations of $ 478 , net of tax of $ 241 for 2013. in 2014 we recorded a gain on the sale of amk of $ 718 , net of tax of $ 758. net income primarily as a result of the restructuring charges along with the other factors discussed above , net income in 2014 was $ 2,567 ( $ 0.18 per diluted share ) compared with a net income of $ 6,459 ( $ 0.47 per diluted share ) in 2013 . adjusted ebitda the increase compared with 2013 was primarily due to an increased add back due to restructuring offset by lower net income . 34 adjusted ebitda is a non-gaap measure that we believe provides an important indicator of our ongoing operating performance . our aggregate depreciation , amortization of purchased intangible assets , restructuring charges and stock-based compensation expense for 2014 and 2013 was $ 23,523 and $ 15,669 , respectively . these aggregate charges represent a significant percentage of the consolidated operating income that we reported for these periods . as discussed above , we use non-gaap ebitda and adjusted ebitda in our operational and financial decision-making and believe that these non-gaap measures facilitate a more meaningful and accurate comparison of the operating performance of our two business segments than do certain gaap measures . the following is a reconciliation of the most directly comparable gaap measure to adjusted ebidta . replace_table_token_12_th business segment financial information we primarily evaluate performance and allocate resources based on segment revenues , operating income and adjusted ebitda as well as projected future performance . segment operating income is defined as revenues less expenses identifiable to the segment . segment operating income will reconcile to consolidated income before income taxes by deducting unallocated corporate expenses , including stock-based compensation , net other expense , net interest expense , income tax provision , and income from discontinued operations . for the years ended december 31 , 2015 , 2014 and 2013 , the proportion of consolidated revenues and segment operating income attributed to each segment was as follows : december 31 , 2015 december 31 , 2014 december 31 , 2013 nobelclad percent of net sales 54 % 48 % 59 %

unallocated corporate expenses and stock-based compensation expense which are not allocated to our business segments . nobelclad generated operating income in 2015 , while dynaenergetics generated an operating loss . nobelclad 35 year ended december 31 , 2015 compared to year ended december 31 , 2014 replace_table_token_13_th net sales the decrease compared with 2014 primarily was due to unfavorable foreign currency exchange translation of $ 7,710. gross profit the decrease in gross profit and gross profit margin compared with 2014 was due to unfavorable project mix . general and administrative expenses the decrease compared with 2014 primarily was due to a reduction in salaries and wages of $ 113 and a reduction in outside services expenses of $ 97. selling and distribution expenses the decrease compared with 2014 was principally due to a $ 452 decrease in outside sales agents commission expense due to lower sales into territories in which we do n't have a captive sales force , partially offset by a $ 187 increase in salaries and wages . amortization expense the decrease compared with 2014 was due to the complete amortization of nobelclad 's customer relationships as of december 31 , 2014. restructuring expense nobelclad 's restructuring relates to the shifting of the majority of clad metal plate production from facilities in both rivesaltes , france and würgendorf , germany to its manufacturing facility in liebenscheid , germany . operating income nobelclad 's operating income increase d compared with 2014 primarily due to lower restructuring expenses . excluding the reduction of restructuring expenses , operating income decreased $ 2,367 ( 26.5 % ) versus prior year primarily due to lower gross margins from unfavorable project mix .
