Final answer:
Morgan Corporation should credit $247,500 to the "paid-in capital in excess of par" account as a result of the conversion of the $1,800,000 face value bonds using the book value method.
Step-by-step explanation:
To determine the amount Morgan Corporation should credit to the account "paid-in capital in excess of par," as a result of bond conversion using the book value method, we must first find the book value of the bonds converted. First, we calculate the book value per $1,000 bond, which is the face amount ($1,000) minus the proportionate share of the total unamortized bond discount. The unamortized bond discount attributable to the converted bonds is ($750,000 total unamortized discount / $12,000,000 total bond face value) * $1,800,000 converted bond face value, which equals $112,500. Subtracting this from the face value of the converted bonds, we get $1,800,000 - $112,500 = $1,687,500 book value of converted bonds.
To calculate the common stock issued at par value, we multiply the number of bonds converted by the number of shares per bond, then by the par value per share: $1,800,000 / $1,000 * 40 * $20 = $1,440,000. The difference between the book value of the converted bonds and the par value of the common stock issued represents the paid-in capital in excess of par. Thus, $1,687,500 - $1,440,000 = $247,500. Therefore, Morgan should credit $247,500 to the "paid-in capital in excess of par" account.
