I have a non-qualified annuity I purchased back in 2005 for $54,500. In 2010, I entered into a 1035 exchange and received another annuity with same terms and conditions as first. At the time of the exchange, the value of the annuity was $74,143.78. Since then I have been recording the various monthly increases and decreases in the value of the annuity by adding/removing shares @ $1.00. How do I adjust the value and the basis so that only the $52,500 shows up as cost and everything since then as nontaxed additions?
