Accrued warranty amounts expected to be incurred after one year are included in noncurrent other accrued liabilities in the consolidated balance sheet. These amounts total $1.1 million at December 26, 2015 and $1.0 million at December 27, 2014. Prior period long-term accrued warranty amounts have been reclassified to a long-term liability in the December 27, 2014 balance sheet to conform to the current period presentation. This reclassification had no effect on previously reported net income and is considered immaterial.

Standby Letters of Credit

During the ordinary course of business, we provide standby letters of credit instruments to certain parties as required. At December 26, 2015, the maximum potential amount of future payments that we could be required to make under these standby letters of credit was approximately $0.2 million. We are required to maintain deposits of cash or other approved investments, which serve as collateral, in amounts that approximate our outstanding standby letters of credit. 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.

Lines of Credit

Our wholly owned Ismeca subsidiary has two available lines of credit which provide it with borrowings of up to a total of 2.5 million Swiss Francs. At December 26, 2015 and December 27, 2014 no amounts were outstanding under the lines of credit.
