Depreciation and Amortization Expense

 

Depreciation of equipment and buildings is provided for by the straight-line method over the assets’ estimated useful lives. Amortization of improvements is provided for by the straight-line method over the term of the lease or the assets’ estimated useful lives, whichever is shorter. Licenses and rights, customer relationships, franchise agreements, technology and non-compete agreements arising from acquisitions are amortized by the straight-line method over periods ranging from 2 to 20 years. Depreciation expense was $13.5 million and $11.9 million for the three months ended December 24, 2022 and December 25, 2021, respectively.
