Commitments and Contingencies

11. Commitments and Contingencies

We lease production equipment, vehicles, computer equipment, storage units and office equipment under operating leases expiring at various times through 2016. Lease expense was $1.3 million, $1.2 million, and $1.7 million for the years ended December 28, 2013, December 29, 2012, and December 31, 2011, respectively. Future minimum lease commitments for non-cancelable operating leases are as follows at December 28, 2013 (in thousands):

2014	$	1,145
2015		982
2016		925
2017		597
2018		545
Total	$	4,194

Through the terms of certain of our leases, we have the option to purchase the leased equipment for cash in an amount equal to its then fair market value plus all applicable taxes.

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, we would be required to pay $2.5 million for various materials. During the years ended December 28, 2013, December 29, 2012, and December 31, 2011, we made purchases under these programs totaling $72.7 million, $57.0 million, and $62.9 million, respectively.

At December 28, 2013, we had $0.6 million in standby letters of credit related to our worker’s compensation insurance coverage, and commitments to purchase equipment and land of $1.9 million.

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.
