Agee Storage issued 30 million shares of its $1 par common stock at $15 per share several years ago. Last year, for the first time, Agee reacquired 1 million shares at $13 per share. Assuming that Agee retires shares it reacquires (restores their status to that of authorized but unissued shares), by what amount will Agee's total paid-in capital decline if it now reacquires 1 million shares at $18 per share?
