MARKET RISKS AND CONCENTRATIONS [Abstract]
MARKET RISKS AND CONCENTRATIONS	18.MARKET RISKS AND CONCENTRATIONS The Company's financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents, investment securities and trade accounts receivable. The Company's cash equivalents and investment securities are high-quality debt and equity securities placed with major banks and financial institutions. The Company's trade accounts receivable are generally unsecured. Credit evaluations are performed on all significant customers and updated as circumstances dictate. Concentrations of credit risk with respect to trade accounts receivable are limited due to the large number of customers and their dispersion across geographic areas. With the exception of one customer that accounts for approximately 13.0% of trade accounts and other receivables at December 29, 2013, and approximately 9.7% of net sales for 2013, the Company does not believe it has significant concentrations of credit risk in its trade accounts receivable. At December 29, 2013, approximately 35.3% of the Company's employees were covered under collective bargaining agreements. Substantially all employees covered under collective bargaining agreements are covered under agreements that expire in 2015 or 2016 with the exception of one live operations location where the collective bargaining agreement expired in 2013 and negotiations are ongoing. We have not experienced any labor-related work stoppage at any location in over nine years. We believe our relationship with our employees and union leadership is satisfactory. The Company is currently in negotiations at one location, and there is no assurance that agreement will be reached. In the absence of an agreement, we may become subject to labor disruption at this location, which could have an adverse effect on our financial results. The aggregate carrying amount of net assets belonging to our Mexico operations was $359.0 million and $277.0 million at December 29, 2013 and December 30, 2012, respectively.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
