ABC Corporation is considering an ambitious project. The life of the project is 10 years. The project will involve an initial investment of 170,000 USD. For tax purposes, ABC Corporation will use straight line depreciation.

In each of years 1 to 10, the project expects to generate revenues of 400,000 AZN and incur variable costs of 50% of revenues and fixed costs of 90,000 USD. The corporate tax rate is 30%, and the cost of capital is 10%.

Suppose that managers are worried that the corporate tax rate will be increased immediately after investment is made. Calculate the break-even rate of taxes.
