A firm has a debt$-$to$-$equity ratio of $0\mathrm{.}46,$ debt with a beta of $\backslash$beta D $=0,$ a return on equity of rE $=12\mathrm{.}0\%$ per year, and a market value of $$4\mathrm{.}3$ million. What return do shareholders require if you take the firm through a restructuring process that ends up with a debt$-$to$-$equity ratio $0\mathrm{.}77?$ Assume an idealized world without taxes and with well functioning markets in which the risk$-$free rate is $3\%,$ and the expected return on the market is $10\%.$ Enter your answer in percentage with $2$ decimals $($e$.$g$.12\mathrm{.}34\%=12\mathrm{.}34)$
