“ item 1 - business . ” for additional information on risk factors that could impact our future results , please refer to “ item 1a - risk factors ” in this annual report . critical accounting policies and estimates our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements . the preparation of financial statements , in conformity with generally accepted accounting principles ( “ gaap ” ) in the u.s. , requires management to make estimates and judgments that affect the reported amounts of assets and liabilities

estimates and judgments are subject to an inherent degree of uncertainty and could be material 27 if our actual or expected experience were to change unexpectedly . on an ongoing basis , we re-evaluate our estimates and judgments . due to the covid-19 pandemic , there has been uncertainty and disruption in the global economy and financial markets . we are not aware of any specific event

10-k with the sec . these estimates may change as new events occur and additional information is obtained . actual results could differ materially from these estimates under different assumptions or conditions . we base our estimates and judgments on our historical experience and on other assumptions that we believe are reasonable under the circumstances , the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources . actual results could differ from those estimates and material effects on our operating results and financial position may result . the accounting policies which our management believes involve the most significant application of judgment or involve complex estimation , are inventories and associated reserves ; goodwill and intangibles asset valuations and associated impairment assessments ; revenue reserves ; share-based compensation valuations and income taxes . story_separator_special_tag in fiscal year 2019 , our i & d market revenues increased by $ 19.3 million , or 10.4 % , compared to fiscal year 2018. the increase was related to higher revenue from sales across the product portfolio . in fiscal year 2019 , our data center market revenue decreased by $ 48.0 million , or 29.6 % , compared to fiscal year 2018. the decrease was primarily due to lower revenue related to sales of legacy optical products and lasers , partially offset by the recognition of $ 7.0 million of licensing revenue during the fiscal year ended september 27 , 2019. gross profit . in fiscal year 2019 , our gross profit decreased by $ 25.0 million , or 10.2 % , compared to fiscal year 2018. gross margin of 44.2 % in fiscal year 2019 decreased 110 basis points , compared to fiscal year 2018. gross profit during 2019 was primarily impacted by lower fiscal year 2019 revenue , lower gross profit as a result of the may 2018 sale of the lr4 business and higher inventory reserves primarily associated with data center products , partially offset by the recognition of $ 7.0 million of licensing revenue during fiscal year 2019. research and development . in fiscal year
