How is the taxability of an annuity with the tax undetermined(unknown) in box 2a of the 1099?

[joe7230]

There are amounts in box 5 and 9b.  The distribution code is 7.  Since the entire amount was deemed taxable in 2013(I did not prepare this return) can I assume the entire amount is taxable in future years?  What additional information do I need?

I would assume it is taxable.
