DFB$,$ Inc. expects earnings next year of $$4\mathrm{.}22$ per share, and it plans to pay a $$2\mathrm{.}00$ dividend to shareholders $($assume that is one year from now$).$ DFB will retain $$2\mathrm{.}22$ per share of its earnings to reinvest in new projects that have an expected return of $14\mathrm{.}1\%$ per year.
