critical accounting policies and estimates the preparation of consolidated financial statements in conformity with generally accepted accounting principles in the united states ( “ gaap ” ) requires management to make estimates , judgments and assumptions that affect the reported amounts of assets , liabilities , revenues and expenses , and related disclosure of contingent assets and liabilities . on an ongoing basis , we 28 evaluate our estimates , including those related to revenue recognition , provisions for sales returns and allowances , share-based compensation , income taxes , inventory excess and obsolescence , goodwill and other intangible assets , restructuring , litigation and other contingencies . we base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that are believed to be reasonable under the circumstances when these carrying values are not readily available from other sources . actual results could differ from these estimates , and such differences could affect the results of operations reported in future periods . we believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements . revenue recognition . we recognize revenue when there is persuasive evidence of an arrangement , delivery has occurred , the fee is fixed or determinable , and collection is reasonably assured . if we grant extended payment terms greater than our standard terms for a customer such that collectability is not assured , the revenue and the corresponding cost of goods sold are deferred upon shipment and will be recognized when the payment becomes due provided all other revenue recognition criteria have been satisfied . additional review and approval by management is required for any transaction with extended payment terms that exceed 90 days to determine proper revenue recognition , which may be subject to management judgment . product revenue is generally recognized upon shipment of product to customers , net of accruals for estimated sales returns and rebates . however , some of our sales are made through distributors under agreements allowing for price protection and limited rights of stock rotation on product unsold by the distributors . although title passes to the distributor upon shipment , terms and payment by our distributors is not contingent on resale of the product . product revenue on sales made through distributors with price protection and stock rotation rights is deferred until the distributors sell the product to end customers . deferred revenue less the related cost of the inventories is reported as deferred income . we do not believe that there is any significant exposure related to impairment of deferred cost of sales , as our historical returns have been minimal and inventory turnover for our distributors generally ranges from 60 to 90 days . our sales to direct customers are made primarily pursuant to standard purchase orders for delivery of products . a portion of our net revenue is derived from sales through third-party logistics providers who maintain warehouses in close proximity to our customer 's facilities . revenue from sales through these third-party logistics providers is not recognized until the product is pulled from stock by the customer . the provision for estimated sales returns and allowances on product sales is recorded in the same period the related revenues are recorded . these estimates are based on historical sales returns , analysis of credit memo data and other known factors . in addition , payments to our customers , in cases where products with potential quality issues are not returned to us and the related quality issue can otherwise not be verified , or where the amount of the payment is not sufficiently supported by the fair value of the quality issue , may be recorded as a reduction of revenue . actual returns could differ from these estimates . we account for rebates by recording reductions to revenue in the same period that the related revenue is recorded . the amount of these reductions is based upon the terms agreed to with the customers . share-based compensation . we measure our share-based compensation at the grant date , based on the fair value of the award , and recognize expense over the requisite service period . we amortize share-based compensation expense for time-based awards under the straight-line attribution method over the vesting period . share-based compensation expense for performance-based awards is recognized when it becomes probable that the performance conditions will be met . once it becomes probable that a performance-based award will vest , we recognize compensation expense equal to the number of shares expected to vest multiplied by the fair value of the award at the grant date , which is amortized using the accelerated method . in the case of performance-based awards based on total shareholder return ( “ tsr ” ) , share-based compensation expense is amortized over the requisite service period . for stock purchase rights under the stock purchase plan , the company amortizes share-based compensation expense ratably over the two-year offering period . we estimate the fair value of time-based stock option and stock purchase awards on the date of grant using the black scholes option-pricing model . the fair value of tsr awards is estimated on the date of grant using a monte carlo simulation model since the award is indexed to the price of our common stock as set forth under the terms of the award . the value of the portion of the awards that is ultimately expected to vest is recognized as expense over the requisite service periods . the black-scholes and monte carlo models incorporate various highly subjective assumptions including expected term of awards , expected future stock price volatility , expected dividend yield and risk-free interest rate . story_separator_special_tag these decreases were driven by the previously announced restructuring of our mobile handset platform business . in addition , revenue from our storage products was down by 4 % , mainly due to a decrease in sales of hdd products , offset by strong growth in sales of ssd product . these declines were partially offset by sales growth of 11 % in our networking products , driven by the introduction of new products and increased sales to the enterprise and campus markets . unit shipments were 22 % lower and weighted average selling prices increased 12 % compared to fiscal 2016 , for an overall decline of 13 % . prior to fiscal 2017 , our customers agreed from time to time to take shipments in an earlier fiscal quarter than the fiscal quarter they originally requested delivery . when such agreement would not have occurred but for the request made by marvell , we refer to such transactions internally as “ pull-ins . ” beginning in fiscal 2017 , our policy is not to engage in pull-in transactions and , as a result , there were no such transactions in fiscal 2017. cost of goods sold replace_table_token_7_th the cost of goods sold as a percentage of net revenue was lower for fiscal 2017 due to the $ 81.3 million cmu settlement included in cost of goods sold in 2016 , a reduction in sales of lower margin mobile platform related product and lower material and manufacturing costs . our cost of goods sold as a percentage of net revenue may fluctuate in future periods due to , among other things : changes in the mix of products sold ; the timing of production ramps of new products ; increased pricing pressures 33 from our customers and competitors ; charges for obsolete or potentially excess inventory ; changes in the costs charged by our foundry , assembly and test subcontractors ; product warranty costs ; changes in commodity prices such as gold ; and the margin profiles of our new product introductions . share-based compensation expense replace_table_token_8_th share-based compensation expense for continuing operations decreased by $ 21.2 million in fiscal 2017 compared to fiscal 2016. the decrease was mainly due to lower headcount from the previously announced restructuring of the mobile platform business , as well as from the restructuring announced in november 2016. the cancellation of equity awards related to certain members of our executive management who departed in april 2016 also reduced the expense . these decreases were partially offset by the effect from the acceleration of expense caused by the cancellation of the june 2016 espp purchase because the company was not eligible to issue shares of its common stock due to the delay in the timely filing of its periodic reports with the sec ( see “ note 12 - shareholder 's equity ” in the notes to the consolidated financial statements set forth in part ii , item 8 of this annual report on form 10-k ) . restructuring and other related charges year ended january 28 , 2017 january 30 , 2016 ( in thousands ) cost of goods sold $ — $ 10,292 restructuring and other related charges 105,186 53,251 $ 105,186 $ 63,543 we recorded total restructuring charges and other related charges of $ 105.2 million in fiscal 2017 , which primarily arose from activities related the restructuring plan we announced in november 2016 to restructure our operations to refocus our research and development , increase operational efficiency and improve profitability . the company recorded charges of $ 98.7 million , including severance benefits of $ 41.0 million , the impairment of a $ 45.0 million nonrefundable deposit due to the non-utilization of the related contract , $ 5.4 million for the impairment of equipment and technology licenses , and other exit-related costs of $ 7.3 million associated with the closure of facilities and contract termination penalties . in addition , the company recorded $ 6.5 million related to previous fiscal 2016 restructuring actions , which included the write-off of mobile-related equipment that was previously held-for-sale and the remaining lease obligation for certain floors in one of its israel facilities that were vacated in fiscal 2017. see “ note 8 - restructuring and other related charges ” in the notes to the consolidated financial statements set forth in part ii , item 8 of this annual report on form 10-k for further information . as a result of the restructuring plan announced in november 2016 , we expect to lower annual operating expenses to approximately $ 820 million to $ 830 million . 34 research and development replace_table_token_9_th research and development expense decreased by $ 163.3 million in fiscal 2017 compared to fiscal 2016. the decrease was primarily attributable to $ 91.6 million of lower personnel-related costs , lower costs related to project spending and facility maintenance services of $ 44.0 million , and a reduction in depreciation and amortization expense of $ 9.4 million . these reductions were driven by the restructuring of our mobile platform business as well as the restructuring actions announced in november 2016. selling and marketing replace_table_token_10_th selling and marketing expense decreased by $ 8.3 million in fiscal 2017 compared to fiscal 2016. the decrease was primarily attributable to decreases of $ 7.2 million of marketing communications expenses . general and administrative replace_table_token_11_th general and administrative expense decreased by $ 18.0 million in fiscal 2017 compared to fiscal 2016. the decrease was due to $ 7.1 million of lower charges for various litigation matters and $ 11.4 million of lower costs for the surety bonds related to the litigation with cmu . the decrease also included a $ 9.2 million decrease in legal expenses related to legal services . in addition , the decrease reflected the effect of a $ 15.4 million charge for a cash payment relating to a tax matter to our former chief executive officer approved by the company 's executive compensation committee
