We lease certain of our manufacturing facilities under operating leases. We also lease production equipment, vehicles, computer equipment, storage units and office equipment under operating leases. Our leases have remaining lease terms of 1 year to 8 years, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year. All of our leases are operating leases. We did not recognize right-of-use assets or lease liabilities for certain short-term leases that are month-to-month leases. The lease expense relating to these leases is immaterial. As of January 2, 2021, we had no additional operating or finance leases that have not yet commenced. Our operating leases expire at various times through 2028. Lease expense for the year ended January 2, 2021 and December 28, 2019, includes $6.6 million and $4.7 million, respectively, classified in cost of sales in the accompanying consolidated statement of operations, with the remainder as selling, general and administrative expenses.

We are obligated to purchase certain raw materials used in the production of our products from certain suppliers pursuant to stocking programs. If these programs were cancelled by us, as of January 2, 2021, we would be required to pay $12.1 million for various materials. During the years ended January 2, 2021, December 28, 2019, and December 29, 2018, we made purchases under these programs totaling $227.4 million, $216.0 million and $278.9 million, respectively. The Company expects to utilize its purchase commitments in its normal ongoing operations.

At January 2, 2021, we had $4.0 million in standby letters of credit related to our workers’ compensation insurance coverage.

We are a party to various legal proceedings in the ordinary course of business. Although the ultimate disposition of those proceedings cannot be predicted with certainty, management believes the outcome of any claim that is pending or threatened, either individually or on a combined basis, will not have a materially adverse effect on our operations, financial position or cash flows.
