” critical accounting policies and estimates our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements , which have been prepared in accordance with accounting principles generally accepted in the united states of america . the preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets , liabilities , revenues and expenses and related disclosure of contingent assets and liabilities . on an ongoing basis , we evaluate our estimates , including those related to supplier programs , bad debts , inventories , insurance costs , goodwill , income taxes , contingencies and litigation . 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 the 17 carrying values of assets and liabilities that are not readily apparent from other sources . actual results may differ from these estimates . if actual market conditions are less favorable than those projected by management , additional adjustments to reserve items may be required . we believe the following critical accounting policies affect our judgments and estimates used in the preparation of our consolidated financial statements . revenue recognition revenues are recognized for product sales when title , ownership and risk of loss pass to the customer , or for services when the service is rendered . in the case of stock sales and special orders , a sale occurs at the time of shipment from our distribution point , as the terms of our sales are predominantly fob shipping point . in cases where we process customer orders but ship directly from our suppliers , revenue is recognized once product is shipped and title has passed . in all cases , revenue is recognized once the sales price to our customer is fixed or is determinable and we have reasonable assurance as to the collectability . in certain customer arrangements , we provide services such as inventory management . we may perform some or all of the following services for customers : determine inventory stocking levels ; establish inventory reorder points ; launch purchase orders ; receive material ; put away material ; and pick material for order fulfillment . we recognize revenue for services rendered during the period based upon a previously negotiated fee arrangement . we also sell inventory to these customers and recognize revenue at the time title and risk of loss transfers to the customer . selling , general and administrative expenses we include warehousing , purchasing , branch operations , information services , and marketing and selling expenses in this category , as well as other types of general and administrative costs . allowance for doubtful accounts we maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments . we have a systematic procedure using estimates based on historical data and reasonable assumptions of collectibles made at the local branch level and on a consolidated corporate basis to calculate the allowance for doubtful accounts . excess and obsolete inventory we write down our inventory to its net realizable value based on internal factors derived from historical analysis of actual losses . looking back , we identify items at risk of becoming obsolete , defined as being in excess of 36 months supply relative to demand or movement . we then analyze in a detailed manner the ultimate disposition of the previously identified excess inventory items , such as sold , returned to supplier , or scrapped . this item by item analysis allows us to develop an estimate which represents the historical likelihood that an item identified as being in excess supply ultimately becomes obsolete . on a current basis , we apply the estimate to inventory items currently in excess of 36 months supply , and reduce our inventory carrying value by the derived amount . we revisit and test our assumptions on a periodic basis . historically , we have not had material changes to our assumptions and do not anticipate any material changes in the future . supplier volume rebates we receive rebates from certain suppliers based on contractual arrangements with them . since there is a lag between actual purchases and the rebates received from the suppliers , we must estimate and accrue the approximate amount of rebates available at a specific date . we record the amounts as other accounts receivable on the balance sheet . the corresponding rebate income is recorded as a reduction of cost of goods sold . the appropriate level of such income is derived from the level of actual purchases made by us from suppliers . supplier volume rebate rates have historically ranged between approximately 0.8 % and 1.2 % of sales depending on market conditions . in 2011 , the rebate rate was1.2 % . goodwill and indefinite life intangible assets we test goodwill and indefinite life intangible assets for impairment annually during the fourth quarter using information available at the end of september , or more frequently when events or circumstances occur indicating that their carrying value may not be recoverable . we test for goodwill impairment on a reporting unit level . the evaluation of impairment involves comparing the current fair value of goodwill and indefinite life intangible assets to the recorded value . we estimate the fair value of goodwill using a combination of discounted cash flow analyses and market multiples . assumptions used for these fair value techniques are based on a combination of historical results , current forecasts , market data and recent economic events . we evaluate the recoverability of indefinite life intangible assets using a discounted cash flow analysis based on projected financial information . the determination of fair value involves significant management judgment and we apply our best judgment when assessing the reasonableness of financial projections .
