Prior to the adoption of Financial Accounting Standards Board (“FASB”) ASC 326 “Financial Instruments – Credit Losses", the allowances for uncollectible accounts receivable were based upon the number of days the accounts are past due, the current business and macroeconomic environment, geographic considerations and specific information such as bankruptcy or liquidity issues of its customers. Rather than recognizing losses when they are deemed to be probable, the Company now uses a current expected credit loss model in order to immediately recognize an estimate of credit losses that are expected to occur over the life of the financial instruments, mainly trade receivables. Additionally, the allowance is based upon identified delinquent accounts, customer payment patterns and other analyses of historical data trends. The Company also maintains an allowance for future sales credits related to sales recorded during the year. The estimated allowance is based on historical sales credits issued in the subsequent year related to the prior year and any significant, preapproved open return good authorizations as of the balance sheet date.</span><span style="color:rgba(0,0,0,1);white-space:pre-wrap;font-weight:normal;font-size:10.0pt;font-family:Times New Roman;"> </span></p>
