During the ordinary course of business, we provide standby letters of credit instruments to certain parties as required. At December 28, 2013, the maximum potential amount of future payments that we could be required to make under these standby letters of credit was approximately $0.8 million. We have not recorded any liability in connection with these arrangements beyond that required to appropriately account for the underlying transaction being guaranteed. We do not believe, based on historical experience and information currently available, that it is probable that any amounts will be required to be paid under these arrangements.
