DBF borrows $$5\mathrm{.}68B$ by issuing $22-$year bonds. ECB's cost of debt is $10\mathrm{.}04\%,$ so it will need to pay interest each year for the next $22$ years, and then repay the principal $$5\mathrm{.}68B$ in year $22.$ ECB's marginal tax rate will remain $42\mathrm{.}38\%$ throughout this period. By how much does the interest tax shield increase the value of DB$?$ NOTE: Provide your answers in Millions. E$.$G$.$ for $100M$ you must enter $100\mathrm{.}0000,$ for $20M$ you must enter $20\mathrm{.}000,$ etc.
