For rate-making purposes other than the determination of subsidy under section 406(b), it is the policy of the Board that Federal income tax expense should be based on the normal taxes that would be paid under the depreciation standards used for rate making, and that accumulated reserves for deferred taxes should be excluded from the recognized capitalization for rate-base purposes.

\1\ Total operating expense for all operations and service (in
millions).\2\ Scheduled all-cargo operations expense.\3\ Total scheduled-service cargo revenue, less scheduled all-cargo
operations revenue, carried as a by-product in aircraft belly
compartments. Includes freight, express, priority and non-priority
U.S. mail, and excess baggage.\4\ Total non-scheduled revenues times 0.95, assuming charter operations
would only be conducted at a profit.\5\ Total transport-related expense, less any excess of expense over
total transport-related revenues.\6\ We here project costs from April 1, 1979 (the midpoint of the data
year ended September 1979) to April 1, 1980 the resultant increase
factor effective through April 30, 1980.\7\ Operating expense per ASM for year-ended September, 1979, times
projected change.\8\ Projected operating expense per ASM on April 1, 1980 divided by the
operating expense as at July 1, 1977.\9\ Adjustment results in a 2.5 percent increase in level over current
January 1, 1980 factor.\10\ Additional rental expense that would have been incurred had leases
not been capitalized under FASB-13, less actual amortization of
capitalized lease expense.\11\ Total fuel cost, scheduled service, times complement of rate of All-
Cargo expense to total Operating Expense.\12\ Order 77-7-26.\13\ Year ended March, 1977 cost per ASM, times cost escalation factor
of 1.04543 (to July 5, 1977). See DPFI workpapers, Y.E. March, 1977.\14\ Estimated average cost per gallon for the trunk plus local service
carriers at April 1, 1980, divided by the average for the year ended
September, 1979 (48.33[cent]).\15\ Change in Trunks plus Locals cost per ASM as at April 1, 1980, to
year ended September, 1979 times total Psgr/Cargo cost for the year
ended September, 1979.\16\ Includes Alaskan, Hawaiian and other regional carriers. [PS-92, 45 FR 24119, Apr. 9, 1980] Subpart D [Reserved]
