Dutch to English Bus/Financial Finance (general)

I am currently translation a business plan (vehicle leases) and am struggling to find an appropriate translation for the above term.

The context is as follows:

"Het open calculatie resultaat is lager dan in 2006 doordat in 2006 nog veel [name] auto’s zijn beëindigd, hetgeen auto’s waren met een hoge kostprijs (lage restwaarde)."

All suggestions welcome - KudoZ points will be awarded within 72 hours.

Many thanks,

Anne
