depreciation or amortization
(i) For purposes of subparagraph (2) of this paragraph, the term depreciation or amortization includes allowances (and amounts treated as allowances) for depreciation (or amortization in lieu thereof), and deductions for amortization of emergency facilities under section 168. Thus, for example, such term includes a reasonable allowance for exhaustion, wear and tear (including a reasonable allowance for obsolescence) under section 167, an expense allowance (additional first-year depreciation allowance for property placed in service before January 1, 1981), under section 179, an expenditure treated as an amount allowed under section 167 by reason of the application of section 182(d)(2)(B) (relating to expenditures by farmers for clearing land), and a deduction for depreciation of improvements under section 611 (relating to depletion). For further examples, the term depreciation or amortization includes periodic deductions referred to in 1.162-11 in respect of a specified sum paid for the acquisition of a leasehold and in respect of the cost to a lessee of improvements on property of which he is the lessee. However, such term does not include deductions for the periodic payment of rent.
