cost of gtees exercises

Hi there,
i am having two exercises.
sep 14 q2 : where it says the unit fund is projected realistically by allowing the charges.

whereas in exercise apr 2016 q3
it says on a mc basis and the uf is projected net of all charges.

what is the difference between allowing and net and why if it different we are doing it differently?

thanks

 

"allowing for", "net of"
in this context I think they mean the same thing
