Loss on redemption- Bonds Payable 22,000 debit

                Cash                                              312,000 credit

                Discount on Bonds Payable          10,000 credit

--to record the reemption of old-bonds--

Explanation:

<em>call price</em> = 300,000 x 104/100 =          <em>312,000</em>

Bond payable (net) 300,000 - 10,000 = 290,000

Loss at redemption                                   22,000

We should recognize a loss as we are paying for the bonds 312,000 dollars while they are worth 290,000

To do the entry, we will write-off the bonds payable and the discount on bonds account. Wer will credit the cash used on the redemption and debit the expense.

= (185 ÷ 160) × 100

= 115.6
