Accounts receivable outstanding longer than the payment terms are considered past due. We determine our allowance by considering a number of factors, including the length of time trade accounts receivable are past due, our previous loss history, customers’ current ability to pay their obligations to us, and the condition of the general economy and the industry as a whole. We write off accounts receivable when they become uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts.</p>

We attempt to minimize the effect of future price fluctuations related to the purchase of raw materials primarily through forward purchasing to cover future manufacturing requirements, generally for periods from <em style="font-weight: inherit; font-style: normal;">1</em> to <em style="font-weight: inherit; font-style: normal;">12</em> months. As of <em style="font-weight: inherit; font-style: normal;"> September 28, 2019, </em>we have approximately $100 million of such commitments. Futures contracts are <em style="font-weight: inherit; font-style: normal;">not</em> used in combination with forward purchasing of these raw materials. Our procurement practices are intended to reduce the risk of future price increases, but also <em style="font-weight: inherit; font-style: normal;"> may </em>potentially limit the ability to benefit from possible price decreases. Our policy is to recognize estimated losses on purchase commitments when they occur. At each of the last <em style="font-weight: inherit; font-style: normal;">three</em> fiscal year ends, we did <em style="font-weight: inherit; font-style: normal;">not</em> have any material losses on our purchase commitments.</p>
