Cash Equivalents |
Cash Equivalents | 5. Cash Equivalents Cash equivalents consist principally of funds holding only U.S. government obligations, and money market funds, with maturities of three months or less when purchased. As of March 30, 2013, a substantial portion of the Company's cash accounts was concentrated at a single financial institution, which potentially exposes the Company to credit risks. As of March 30, 2013, the financial institution has "stable" credit ratings and the Company has not experienced any losses related to such accounts. The short-term credit rating is A-1 by Standard & Poor's ratings services. The Company does not believe that there is significant risk of non-performance by the financial institution and the Company's cash on deposit at this financial institution is fully liquid. The Company continually monitors the credit ratings of the institution. The carrying amounts of the Company's instruments classified as cash equivalents are stated at amortized cost, which approximates fair value because of their short-term maturity.
