Obviously they'll last much longer than that, but they use standard figures like that to calculate the depreciation and other financial stuffs

If its 7 for minibuses then basically all of GNE solos bar 3 will need replacements, 10 for single 40 buses would need to be replaced with another 20 or smth soon. 

Deckers they're pretty much all under 15 years old.
