Summary of Significant Accounting Policies
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

As of March 30, 2014, our significant accounting policies, which are detailed in our Annual Report on Form 10-K for the year ended December 29, 2013, have not changed.

Marketable securities

We have investments in marketable debt securities. We determine the appropriate classification of our investments at the date of purchase and reevaluate the classifications at the balance sheet date. Marketable debt securities with maturities of 12 months or less are classified as short-term. Marketable debt securities with maturities greater than 12 months are classified as long-term. We have the intent and ability to hold our marketable debt securities until maturity; therefore they are accounted for as held-to-maturity and stated at amortized cost.

Concentration of Risk
    
Financial instruments, which potentially subject us to concentration of risk, are cash and cash equivalents and investments. Cash and cash equivalents are placed with major financial institutions. As of March 30, 2014, we had cash balances at financial institutions in excess of federal insurance limits. We periodically evaluate the credit standing of these financial institutions as part of our ongoing investment strategy.

Our investment portfolio consists of investment-grade securities diversified among security types, issuers and industries. Our cash and investments are primarily managed by third-party investment managers who are required to adhere to investment policies approved by our Board of Directors designed to mitigate risk.

Recently issued accounting pronouncement

In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, which prescribes that a liability related to an unrecognized tax benefit would be offset against a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. In situations in which a net operating loss carryforward, a similar tax loss or a tax credit carryforward is not available at the reporting date under the tax law of a jurisdiction or the tax law of a jurisdiction does not require it, and the Company does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. At the beginning of our 2014 fiscal year, we adopted ASU 2013-11 and it did not have a material impact on our financial statements.
