page 48 Bombardier Inc. Annual Report 2003-04 Current estimated accounting program quantities and the remaining deliveries required to achieve the total accounting program quantity were as follows as at January 31, 2004: $^{(1)}$Remaining deliveries for regional aircraft include 273 firm orders for the Bombardier CRJ Series and 30 firm orders for the Bombardier Q-Series. EOAPC increased by $96 million to $1.4 billion as at January 31, 2004, compared to $1.3 billion as at January 31, 2003. This increase is  mainly due to learning curve costs incurred in programs in their early phases of production, essentially the Bombardier Challenger 300,  the Bombardier Learjet 40, Bombardier * CRJ900$^{*}$, and the Bombardier CRJ700. These increases were partially offset by reductions  in mature programs, where the actual unit  cost is less than the average cost recognized to income. Total program tooling costs amounted  to $2.2 billion as at January 31, 2004, com- pared to $2.3 billion as at January 31, 2003. Depreciation for programs under commer- cial production were partially offset by tooling costs incurred for programs under develop- ment or in their early phases of production (Bombardier Global 5000$^{*}$, Bombardier Challenger 300 and Bombardier Learjet 40). Analysis of program information Deliveries and backlog During fiscal year 2004, Bombardier Aerospace delivered 324 aircraft compared to 298 aircraft for fiscal year 2003. Aircraft delivered during fiscal year 2004 were as follows: 232 regional aircraft, 89 business jets and three amphibious aircraft compared to 220, 77 and one unit respectively for fiscal year 2003. The order backlog amounted to $14.5 billion as at January 31, 2004, compared to $18.7 bil- lion as at January 31, 2003 (including $1.4 billion and $1.7 billion, respectively, for Defence Services). The year-over-year reduction in the backlog reflects higher deliveries versus orders received, as well as a negative foreign exchange adjustment of approximately $1.8 billion, relat- ing to a lower exchange rate for the U.S. dollar compared to the Canadian dollar. Bombardier Aerospace expects total deliv- eries of aircraft for fiscal year 2005 to remain at a similar level as fiscal year 2004. 2003 PROGRAM  PROGRAM FAMILY EOAPC TOOLING TOTAL Regional Aircraft Bombardier CRJ Series $ 334 $ 690 $1,024 Bombardier Q-Series 94 94 188 Business Aircraft Bombardier Learjet Series 379 320 699 Bombardier Challenger 300 – 501 501 Bombardier Challenger 604 – 32 32 Bombardier Global Series  483 679 1,162 $1,290 $ 2,316 $3,606 PROGRAM REMAINING  PROGRAM FAMILY QUANTITIES DELIVERIES (1) Regional Aircraft Bombardier CRJ Series 1,050 504 Bombardier Q-Series 225 63 Business Aircraft Bombardier Learjet Series 725 400 Bombardier Challenger 300 300 293 Bombardier Challenger 604 150 74 Bombardier Global Series 450 316 F02 F03 F04 Aircraft deliveries (NUMBER OF UNITS) 400 300 200 100 0 Regional aircraft Business aircraft Total 220 77 162 206 368 297 89 232 321
