our goal is to expand the functionality of our products , provide access to new customers and markets , and increase our production capacity . 2013 developments several important corporate developments occurred in 2013 that have had a significant impact on the presentation of our consolidated financial results . exone was formed on january 1 , 2013 , when the ex one company , llc , a delaware limited liability company , merged with and into a delaware corporation , which survived and changed its name to the exone company . as a result of our reorganization on january 1 , 2013 , the ex one company , llc became exone , the common and preferred interest holders of the ex one company , llc became holders of common stock and preferred stock , respectively , of exone , and the subsidiaries of the ex one company , llc became the subsidiaries of exone . the consolidated financial statements include the accounts of exone , its wholly-owned subsidiaries , exone americas llc ( united states ) , exone gmbh ( germany ) , effective in august 2013 , exone property gmbh ( formerly exone holding deutschland gmbh ) ( germany ) , exone kk ( japan ) and through march 27 , 2013 two variable interest entities in which exone was identified as the primary beneficiary , lone star metal fabrication , llc and troy metal fabricating , llc . on march 27 , 2013 , exone americas llc acquired certain assets , including property and equipment ( principally land , buildings and machinery and equipment ) held by the two vies , and assumed all outstanding debt of such vies . following this transaction , neither of the entities continued to meet the definition of a vie with respect to exone , and as a result , the remaining assets and liabilities of both entities were deconsolidated following the transaction . on february 6 , 2013 , we commenced an initial public offering of 6,095,000 shares of our common stock at a price to the public of $ 18.00 per share , of which 5,483,333 shares were sold by us and 611,667 were sold by a selling stockholder ( including consideration of the exercise of the underwriters ' over-allotment option ) . following completion of the offering on february 12 , 2013 , we received net proceeds of approximately $ 91,996 ( net of underwriting commissions ) . in addition , we incurred associated offering costs of approximately $ 1,625 , including approximately $ 712 in offering costs previously paid and deferred by us at december 31 , 2012 . 41 on september 9 , 2013 , we commenced a secondary public offering of 3,054,400 shares of our common stock at a price to the public of $ 62.00 per share , of which 1,106,000 shares were sold by us and 1,948,400 were sold by selling stockholders ( including consideration of the exercise of the underwriters ' over-allotment option ) . following completion of the offering on september 13 , 2013 , we received net proceeds of approximately $ 65,315 ( net of underwriting commissions ) . in addition , associated offering costs of approximately $ 1,012 were incurred in connection with this offering . associated offering costs incurred by us in connection with the secondary public offering ( $ 367 ) were based on our pro-rata sale of shares as compared to selling stockholders , who were responsible for their pro-rata portion ( $ 645 ) . 2014 developments on march 3 , 2014 , exone americas purchased ( i ) substantially all the assets of machin-a-mation , a specialty machine shop located in chesterfield , michigan , and ( ii ) the real property on which machin-a-mation 's business is located for an aggregate purchase price of approximately $ 5.0 million . the machin-a-mation business will remain in its current michigan location , complementing our nearby psc in troy , michigan . this psc focuses on advanced 3d printed cores and molds for the aerospace and shipbuilding industries . in addition , we expect to continue to serve and expand the existing machin-a-mation industrial customer base . we believe that machin-a-mation 's specialty precision machining expertise helps us address the finishing requirements for complex parts which are cast from our 3d printed sand molds . on march 6 , 2014 , exone gmbh acquired all of the shares of mwt-gesellschaft für industrielle mikrowellentechnik mbh , a pioneer in industrial grade microwaves with leading design and manufacturing experience based in elz , germany , for approximately $ 4.8 million . story_separator_special_tag this decrease was principally due to a lower average outstanding debt balance in 2012 as compared to 2011 , mostly due to the conversion of amounts payable on our demand note payable to member to redeemable preferred units in december 2011. other income  net other income  net for 2013 was $ 98 compared with other income  net of $ 221 for 2012 and other income  net of $ 158 for 2011. amounts for all periods consist principally of interest income on cash deposits and other financing activity benefits . provision for income taxes the provision for income taxes for 2013 , 2012 and 2011 was $ 370 , $ 995 and $ 1,031 , respectively , and in each of the respective years related entirely to the taxable income of exone gmbh . the effective tax rate for 2013 , 2012 and 2011 was 106.2 % , 111.5 % and 115.7 % , respectively . for 2013 , the effective tax rate differed from the u.s. federal statutory rate of 34.0 % primarily due to net changes in valuation allowances for the period . for 2012 and 2011 , the effective tax rate differed from the u.s. federal statutory rate of 34.0 % primarily due to the effects of ( i ) limited liability company losses not subject to tax and ( ii ) net changes in valuation allowances for the period . we have provided a valuation allowance for our net deferred tax assets as a result of our inability to generate consistent net operating profits in jurisdictions in which we operate . as such , any benefit from deferred taxes in any of the periods presented in our consolidated financial statements has been fully offset by changes in the valuation allowance for net deferred tax assets . we continue to assess our future taxable income by jurisdiction based on ( i ) our recent historical operating results ( ii ) the expected timing of reversal of temporary differences ( iii ) various tax planning strategies that we may be able to enact in future periods ( iv ) the impact of potential operating changes on our business and ( v ) our forecast results from operations in future periods based 47 on available information at the end of each reporting period . to the extent that we are able to reach the conclusion that deferred tax assets are realizable based on any combination of the above factors , a reversal of existing valuation allowances may occur . noncontrolling interests net income attributable to noncontrolling interests for 2013 was $ 138 compared with net income attributable to noncontrolling interests of $ 480 in 2012 , a decrease of $ 342 , or 71.3 % . there was no net income attributable to noncontrolling interests for 2013 following the acquisition of net assets in the related variable interest entities described immediately below , which was completed during the quarter ended march 31 , 2013. net income attributable to noncontrolling interests for 2012 was $ 480 compared with net income attributable to noncontrolling interests of $ 420 in 2011 , an increase of $ 60 , or 14.3 % . this increase was principally due to additional rental income ( rental expense for exone ) associated with 3d printing machines purchased by our variable interest entities , lone star and tmf . impact of inflation our results of operations and financial condition are presented based on historical cost . while it is difficult to accurately measure the impact of inflation due to the imprecise nature of the estimates required , we believe the effects of inflation , if any , on our results of operations and financial condition are not significant . story_separator_special_tag borrowings on the demand note payable to member of $ 3,939 to support operations , ( ii ) proceeds from long-term debt of $ 2,398 used to finance 3d printing machine production and ( iii ) contributions from noncontrolling interests of $ 402. offsetting these sources of cash were long-term debt repayments of $ 808. contractual obligations we are required to make future payments under various contracts , including operating lease and license agreements , construction services agreements , debt agreements and capital and financing lease agreements . at december 31 , 2013 , a summary of our outstanding contractual obligations is as follows : replace_table_token_10_th operating leases operating leases consist of various lease agreements of manufacturing facilities , office and warehouse spaces , and equipment and vehicles , expiring in various years through 2019. license fee obligations license fee obligations include amounts contractually due to third parties for use of patented technology , expiring in various years through 2016 . 50 deferred revenue and customer prepayments deferred revenue and customer prepayments require us to deliver products or services to customers over a specified contract period . while these obligations are not expected to result in cash payments , they represent contractual obligations for which we would be obligated if the specified deliveries could not be made . capital expenditures capital expenditures consist of firmly committed amounts under a construction services contract for the design and construction of a manufacturing facility in the municipality of gersthofen , germany , with an expected completion date in the fourth quarter of 2014. other amounts otherwise disclosed within this annual report on form 10-k associated with the design , construction and building improvements related to this facility were not contractually committed at december 31 , 2013. long-term debt long-term debt consists of the current and noncurrent portion of a note payable used to finance the acquisition of a building . maturity of this debt instrument extends to 2027. capital and financing leases capital and financing leases consist of obligations associated with ( i ) leased assets or ( ii ) sale-leaseback transactions required to be accounted for as financings .

liquidity and capital resources we incurred net losses of approximately $ 6,317 , $ 9,688 and $ 7,617 for 2013 , 2012 and 2011 , respectively . prior to our reorganization , we operated as a limited liability company and were substantially supported by the continued financial support provided by our majority member . in connection with the completion of our initial public offering in february 2013 and our secondary public offering in september 2013 , we received total unrestricted net proceeds from the sale of our common stock of approximately $ 157,311. we believe that the unrestricted net proceeds obtained through these transactions will be sufficient to support our operations through january 1 , 2015. the following table summarizes the significant components of cash flows for each of the years ending december 31 : replace_table_token_9_th operating activities cash used for operating activities for 2013 was $ 20,192 compared with $ 9,677 for 2012. the increase of $ 10,525 , or 108.8 % , was mostly attributed to an increase in our net loss less depreciation and equity-based compensation of $ 2,964 mostly due to increased operating expenses following our public offering in february 2013 and net changes in assets and liabilities as a result of ( i ) an increase in outflows associated with inventories 48 ( as a result of increases in global machine manufacturing activities ) , ( ii ) an increase in outflows associated with prepaid expenses and other current assets ( attributed mostly to an increase in value-added taxes paid ( refundable ) and an increase in supplier prepayments ) , ( iii ) a decrease in inflows associated with accounts payable and accrued expenses and other liabilities ( based on increased purchasing activity and the timing of payment ) and ( iv ) an increase in outflows associated with deferred revenue and customer prepayments ( mostly due to the timing and amount of prepayments by customers ) . these amounts were offset by increased collections activity on accounts receivable .
