(a) (1) The Department generally does not allow air carriers to include in their calculations aircraft impairment charges, charges or expenses attributable to lease buyouts, or other losses that are not actually and fully realized in the period between September 11, 2001 and December 31, 2001.

(2) The Department will consider requests to accept adjustments for extraordinary or non-recurring expenses or revenues on a case-by-case basis. If, as a carrier, you make such a request, you must demonstrate the following to the satisfaction of the Department:

(i) That the expense or revenue was (or was not, as appropriate) the direct result of the terrorist attacks of September 11, 2001;

(ii) That the revenue or expense was reported in accordance with Generally Accepted Accounting Principles (GAAP), except to the extent that the GAAP would require or allow treatment that would be inconsistent with the Act or this part;

(iii) That an expense was fully borne within the September 11—December 31, 2001, period and is permanent; and

(iv) That the resulting additional compensation would not be duplicative of other allowances for compensation.

(b) The Department generally does not accept claims by air carriers that cost savings should be excluded from the calculation of incurred losses. Consequently, the Department will generally not allow such claims to be used in a way that has the effect of increasing the compensation for which an air carrier is eligible.
