Is there a source for a history of a mutual fund?

[Periwinkle65]

I need to determine my cost basis for Highland Global Allocation Fund. It is impossible to reach anyone at the fund at this time due to "an office emergency." They did inform me that I purchased the fund in 2011. Is there some way that I might ascertain the basis in 2011 online. Unfortunately I do not have my confirmation of purchase. 

Thanks.
