Pre-Production Costs Related to Long-Term Supply Arrangements
 
We incur pre-production tooling costs related to products produced for our customers under long-term supply agreements.  We had $10.5 million for both the fiscal year ended May 2, 2015 and May 3, 2014 of pre-production tooling costs related to customer-owned tools for which reimbursement is contractually guaranteed by the customer or for which the customer has provided a non-cancelable right to use the tooling.  Engineering, testing and other costs incurred in the design and development of production parts are expensed as incurred, unless the costs are reimbursable, as specified in a customer contract.
