Suppose a firm has a tax loss of $5 million in the current period. The firm%u2019s after-tax discount rate is 10%. Over the preceding 5 years the firm has reported the following taxable income.
-  -5         -4         -3         -2         -1         Current
- Year 
- Taxable Income ($ millions)                  $1        $1        $1.5     $3        $3        -$5
- Statutory Tax Rate                                40%     40%     35%     35%     30%     30%
If the carryback period is 3 years, what is the firm%u2019s marginal explicit tax rate in the current period?
 If the carryback period is 2 years, what is the firm%u2019s marginal explicit tax rate in the current period?
 Suppose the carryback period is 2 years and taxable income in period -1 was only $1 million. What is the firm%u2019s marginal explicit tax rate (mtr) in the current period? Select from below (only one answer).
-  The mtr is the same as the answer to a. above
-  The mtr is the same as the answer to b. above
Can carryback only $4 of the $5 million loss so we still have a $1 million tax loss carryforward and mtr is the PV of the statutory tax rate in the period in which the tax loss carryforward is used up.
