You have been hired as a consultant for ABC Investment Group. ABC incorporated in 1999 and manages investment portfolios for small to medium size companies. The Director of the company is not up to speed on how unrealized gains and losses, as well as realized gains and losses on bonds, should be accounted for. The Director has been told that under certain conditions unrealized gains and losses can be accounted for in the income statement and accounted for as part of other comprehensive income under other conditions. The Director is also unclear as to how to determine whether a security is impaired and how to determine the amount that is required to be written down. You have been asked to look into these issues and determine the proper accounting treatment for bonds.
