| The assumptions for this table are the same as for Table 5, except in this case the amount converted from the deductible IRA is $500,000, pushing the investor into the 38.25% tax bracket. The tax due on the converted amount is $178,203, which is the amount that would be invested in the tax savings account if the conversion is not done.
