Fair Value of Financial Instruments
Fair Value of Financial Instruments

The methods and assumptions used to estimate the fair value of each class of financial instrument are as follows:

Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities:

The carrying amounts approximate fair value because of the short maturity of these instruments.

Long-Lived Assets

As further described in Note 3—"Summary of Significant Accounting Policies," the Company regularly reviews long-lived assets (primarily property and equipment) for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. When the estimated fair value is determined to be lower than the carrying value of the asset, an impairment charge is recorded to write the asset down to its estimated fair value.
    
Based on the Company’s analysis relative to long-lived assets, there were no impairments recorded during the years ended December 27, 2012, December 29, 2011 or December 30, 2010.

Long term obligations, excluding capital lease obligations:

The fair value of the Company’s debt obligations were based on recent financing transactions for similar debt issuances and the carrying amounts approximate the fair value.
