on an ongoing basis , we evaluate our estimates , including those related to revenue recognition under the percentage-of-completion method , bad debts , inventories , warranty reserves , investment valuations , valuation of stock compensation awards , recoverability of deferred tax assets , liabilities for uncertain tax positions and contingencies . we base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances , the results of which form the basis for making judgments about carrying values of assets and liabilities that are not apparent from other sources . actual results may differ from these estimates under different assumptions . the prior period amounts have been revised for the impact of discontinued operations due to the sale of our iii-v product line , including our ktc subsidiary . our financial results for prior periods have also been revised , in accordance with u.s. gaap , to reflect certain changes to the business and other matters . we believe the following critical accounting policies are most affected by our more significant judgments and estimates used in the preparation of our consolidated financial statements : revenue recognition we recognize revenue if four basic criteria have been met : ( 1 ) persuasive evidence of an arrangement exists ; ( 2 ) delivery has occurred and services rendered ; ( 3 ) the price to the buyer is fixed or determinable ; and ( 4 ) collectability is reasonably assured . we do not recognize revenue for products prior to customer acceptance unless we believe the product meets all customer specifications and has a history of consistently achieving customer acceptance of the product . provisions for product returns and allowances are recorded in the same period as the related revenues . we analyze historical returns , current economic trends and changes in customer demand and acceptance of product when evaluating the adequacy of sales returns and other allowances . certain product sales are made to distributors under agreements allowing for a limited right of return on unsold products . sales to distributors are primarily made for sales to the distributors ' customers and not for stocking of inventory . we delay revenue recognition for our estimate of distributor claims of right of return on unsold products based upon our historical experience with our products and specific analysis of amounts subject to return based upon discussions with our distributors or their customers . we recognize revenues from long-term research and development government contracts on the percentage-of-completion method of accounting as work is performed , based upon the ratio of costs or hours already incurred to the estimated total cost of completion or hours of work to be performed . revenue recognized at any point in time is limited to the amount funded by the u.s. government or contracting entity . we recognize revenue for product development and research contracts that have established prices for distinct phases when delivery and acceptance of the deliverable for each phase has occurred . in some instances , we are contracted to create a deliverable which is anticipated to go into full production . in those cases , we discontinue the percentage-of-completion method after formal qualification of the deliverable has been completed and revenue is then recognized based on the criteria established for sale of products . in certain instances qualification may be achieved and delivery of production units may commence however our customer may have either identified new issues to be resolved or wish to incorporate a newer display technology . in these circumstances new units delivered will continue to be accounted for under the criteria established for sale of products . under certain of our research and development contracts , we recognize revenue using a milestone methodology . this revenue is recognized when we achieve specified milestones based on our past performance . we classify amounts earned on contracts in progress that are in excess of amounts billed as unbilled receivables and we classify amounts received in excess of amounts earned as billings in excess of revenues earned . we invoice based on dates specified in the related agreement or in periodic installments based upon our invoicing cycle . we recognize the entire amount of an estimated ultimate loss in our financial statements at the time the loss on a contract becomes known . accounting for design , development and production contracts requires judgment relative to assessing risks , estimating contract revenues and costs , and making assumptions for schedule and technical issues . due to the size and nature of the work 24 required to be performed on many of our contracts , the estimation of total revenue and cost at completion is complicated and subject to many variables . contract costs include material , labor and subcontracting costs , as well as an allocation of indirect costs . we have to make assumptions regarding the number of labor hours required to complete a task , the complexity of the work to be performed , the availability and cost of materials , and performance by our subcontractors . for contract change orders , claims or similar items , we apply judgment in estimating the amounts and assessing the potential for realization . these amounts are only included in contract value when they can be reliably estimated and realization is considered probable . we have accounting policies in place to address these as well as other contractual and business arrangements to properly account for long-term contracts . if our estimate of total contract costs or our determination of whether the customer agrees that a milestone is achieved is incorrect , our revenue could be overstated and profits would be negatively impacted . story_separator_special_tag accordingly , sales of 3d metrology equipment are tied to the strength of the chinese manufacturing sector . the decrease in the consumer applications is the result of a decrease in sales of our products for use in digital still cameras ( dscs ) . we believe the overall market for dscs has been declining due to an increase in use of cameras in smartphones . the decrease in research and development revenues is the result a decrease in funding from the u.s. government partially offset by an increase in funding by customers to develop wearable technologies . international sales represented 32 % and 38 % of product revenues for fiscal years 2015 and 2014 , respectively . our international sales are primarily denominated in u.s. currency . consequently , a strengthening of the u.s. dollar could increase the price in local currencies of our products in foreign markets and make our products relatively more expensive than competitors ' products that are denominated in local currencies , leading to a reduction in sales or profitability in those foreign markets . in addition , our korean subsidiary , kowon , holds u.s. dollars in order to pay various expenses . as a result , our financial position and results of operations are subject to exchange rate fluctuations in transactional and functional currency . we have not taken any protective measures against exchange rate fluctuations , such as purchasing hedging instruments with respect to such fluctuations , because of the historically stable exchange rate between the japanese yen , korean won and the u.s. dollar . cost of product revenues . replace_table_token_12_th cost of component revenues , which is comprised of materials , labor and manufacturing overhead related to the production of our products increased as a percentage of

replace_table_token_13_th research and development ( r & d ) expenses are incurred in support of internal display development programs or programs funded by agencies or prime contractors of the u.s. government and commercial partners . in fiscal year 2016 , our r & d expenditures will be related to our display products , overlay weapon sights and kopin wearable technologies . r & d revenues associated with funded programs are presented separately in revenue in the statement of operations . r & d costs include staffing , purchases of materials and laboratory supplies , circuit design costs , fabrication and packaging of display products , and overhead . funded r & d expense for 2015 decreased as compared to the prior year due to a reduction in programs with customers developing products for wearable applications . the decrease occurred because the customers either discontinued the programs or the products moved into the commercialization phase . 29 selling , general and administrative . selling , general and administrative ( s , g & a ) expenses consist of the expenses incurred by our sales and marketing personnel and related expenses , and administrative and general corporate expenses . replace_table_token_14_th the decrease in s , g & a expenses in 2015 as compared to 2014 is primarily attributable to a decrease in deferred compensation expense , professional

of interest income , foreign currency transactions and remeasurement gains and losses incurred by our korean and united kingdom subsidiaries , gains on sales of investments and the impairment of cost

million foreign currency gains for 2014 . this was primarily attributable to increased fluctuations in the u.s. dollar and korean won currency exchange rate . in 2015 , we recorded a gain on the sale of investments of $ 9.2 million consisting of gains from the sale of investments in vuzix and recon of $ 3.7 million and $ 5.5 million , respectively . in 2014 , we recorded an impairment of $ 1.3
