Without leverage, Impi Corporation will have net income next year of $ 5.5 million. If Impi's corporate tax rate is 21 % and it pays 9 % interest on its debt, how much additional debt can Impi issue this year and still receive the benefit of the interest tax shield next year? (Note: Assume Impi's revenues exceed $ 25 million, and that interest tax deductions are limited to 30 % of EBIT under the TCJA.)

The debt is ____million. (Round to three decimal places.)
