Final answer:
Nichols Corporation will reduce its before-tax net income by $10,000, which is the credit loss amount determined for the other-than-temporarily impaired Holly Inc. bonds.
Step-by-step explanation:
When Nichols Corporation determines that the Holly bonds are other-than-temporarily impaired due to credit losses, the before-tax net income will need to be adjusted accordingly. Only the credit loss portion, that Nichols calculates as $10,000, will affect the net income. The noncredit losses associated with other factors impacting the fair market value do not affect the income statement because the investment is classified as held to maturity.
Since we are dealing with an impairment loss associated with a credit loss, we would recognize this impairment in the income statement, thus reducing the net income. The impairment loss recognized is the amount that Nichols concludes will not be recoverable, which is the $10,000 related to credit losses.
