Endowment - Large Difference between "Gross Fund Value" and "Cash Value"

siriusfire

Hello

I have an old Friends Provident/Friends Life endowment due for maturity next year. On checking the values I've noticed a huge difference between the current "Cash Value" and the "Gross Fund Value" - with the cash value being about £20,000 more than the Fund value.

Is this normal for an investment about to reach maturity or have they done some bad maths?

Thanks in advance SF
