Rolls-Royce's exit from the International Aero Engines business has been reflected in fewer engine deliveries over the course of last year.
It delivered 668 civil aero engines in 2012. While this is a fall from the 2011 level of 962, the manufacturer points out that 418 of those engines were IAE V2500s.
Rolls-Royce completed the sale of its 32.5% share of the IAE business to Pratt & Whitney last year.
But in its end-of-year financial results Rolls-Royce points out that its 2012 engine deliveries still exceed, by 23%, the restated 2011 figure of 544.
It generated a 16% rise in underlying revenue, the manufacturer adds. Original equipment revenues performed strongly, up by 31%, while services revenues increased by 5%.
Over the year the order book rose by 5% to nearly £50 billion ($77 billion). New orders totalled £10.3 billion and the restated figures exclude IAE orders worth nearly £4.6 billion.
Trent engine make up around 75% of the order book.
Rolls-Royce's underlying profit for the civil engine division, before financing, increased by 46% to £727 million. This includes £92 million arising from restructured trading arrangements with IAE.
