7. Asset Retirement Obligations

The Company recognizes asset retirement obligations in the period in which they are incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company continues to depreciate, on a straight-line basis, the amount added to property, plant and equipment and recognizes accretion expense in connection with the discounted liability over the various remaining lives which range from approximately one to thirty-two years.

A reconciliation of the Company's asset retirement liability is as follows (in thousands):

   
November 24, 2012
 
Beginning balance as of August 25, 2012
 $10,120 
Accretion expense
  166 
Ending balance as of November 24, 2012
 $10,286 

Asset retirement obligations are included in long-term accrued liabilities in the accompanying Consolidated Balance Sheet.
