To ensure credit, insert comments in column headings or individual cells. For example: “In this column, the numbers for the 200x income statement came from the 200x 10-k statement, downloaded from Southwest.com” or “See p. xxx of the Southwest 10-k for Dec. 31, 2006, available at http://southwest.investorroom.com/sec-filings ” http://southwest.investorroom.com/sec-filings The income component calculations, which should add up to the annual differences, are most important.

Cost Effect of Growth for Variable Costs—SWA-- Salaries/Wage Expense Cost Effect of Growth for Salaries/wage expense (2004 RPMs/2003 RPMs)* (Number of Employees, end of last year) (Number of Employees, end of last year) = X_ Salaries/ Wage Expense per EE Note: RPM is Revenue Passenger Miles, the activity level.

Cost Effect of Growth for Variable Costs—SWA--Fuel, Commissions, Landing Fees Cost Effect of Growth for Fuel, Commissions, Landing Fees (2004 RPMs/2003 RPMs)* (Number of Trips Flown) Actual Units of Input Used to Produce Prior Period Output = X_ Fuel, Commn, Landing Fees and Other Rentals Expense per Trip Note: RPM is Revenue Passenger Miles, the activity level.

9. (c) 2012 Pearson Prentice Hall. All rights reserved. Cost Effect of Growth for Fixed Costs--SWA I threw you something of a curveball here, because we did not cover situations where capacity requirements are increasing. The equation for cell C45 is: =(((C13/B13)*B31)-B31)*B28 That is, use the same method as for the variable costs.

Cost Effect of Price Recovery Variable costs: Input prices are annual salaries for employees; Fuel, Commissions, Landing Fees and Other Rentals Expense per Trip for trips flown; Maintenance, Aircraft Rental, Depreciation, Other Expenses per Aircraft Seat for Estimated capacity in aircraft seats

Cost Effect of Price Recovery--SWA Input prices are: annual salaries--for employees; Fuel, Commissions, Landing Fees and Other Rentals Expense per Trip--for trips flown; Maintenance, Aircraft Rental, Depreciation, Other Expenses per Aircraft Seat--for Estimated capacity in aircraft seats Moreover, here is the formula for cell C56: =(C28-B28)*((C13/B13)*B31)

14. © 2012 Pearson Prentice Hall. All rights reserved. Cost Effect of Productivity for VC--SWA “Number of employees” is one input. To get units required last period, multiply last period’s requirement by (This year’s RPM)/(Last Year’s RPM). The other two “inputs” (p. 541) are flight departures (or trips) and aircraft seats. Treat them the same way.
