In: Accounting
A firm uses corn as an input into their production of ethanol. You require 1 bushel of corn to produce one gallon of ethanol. Each gallon of ethanol sells for $4. Fixed costs are $12, and you can produce and sell 10 gallons of ethanol this year. Corporate taxes on profits follow a progressive pattern, and are as follows:
Tax Bracket |
Tax rate |
First $4 of pre-tax profit |
10% |
Next $6 of pre-tax profit |
15% |
Next $8 of pre-tax profit |
40% |
Pre-tax profit greater than $18 |
50% |
For illustrative purposes, assume that all cash flows occur at the end of the year (i.e. assume that all corn is purchased and ethanal produced and sold at the end of the year). This way, there is no adjustment for time value of money required to calculate profit.
Suppose that the price of corn will follow the following distribution one year from now:
Corn Price |

1.00 |
0.25 |
2.00 |
0.25 |
3.00 |

The following one-year call options are available on the price of corn. The risk free rate is 5% compounded continuously:

The one year forward price of corn is 2.79 per bushel.
