S&S Isa, differences in reported and actual returns

Saadine

Hi, I've had around £70K in the Co-ops Sustainable Leaders Trust, they report the trust has improved by 15.90% in the 2013/14 financial year. But the actual money returns that show in my valuation statement, show only about 6% increase in the same time period.
I have been to Co-op and spoken to someone on their helpline, but they can't/won't explain the difference. On the website they directed me to, the report showed the Trust running at 20%. I only wanted guidance, I appreciate there are charges in running the trust but they wouldn't give out any information!
Any ideas at the reasons for the difference would be appreciated.
Best wishes Amer

Valuation statements are normally 6 monthly or yearly.

You need to compare like with like though. So make sure the time periods are identical and the returns will match too. 1 year from March 2013 will be different to 1 year from June 2013.
