STEP-BY-STEP ANSWER:
Step 1: Determine whether the investment is classified under debt or equity and select the corresponding measurement basis (amortized cost for debt investments, fair value for equity investments).
Step 2: For investments at amortized cost, adjust the carrying value over time using the effective interest rate method and account for any premiums or discounts.
Step 3: For investments at fair value, adjust the carrying amount to reflect current market conditions and value fluctuations.
Step 4: Evaluate the investment for impairment by comparing its carrying value to its recoverable amount.
Step 5: If an impairment is identified, write down the carrying amount to the recoverable amount and recognize an impairment loss in the income statement.
Final Answer: The carrying value of the investment is adjusted based on the chosen measurement method, and impairments are recognized to ensure that the investment is not overstated on the financial statements.
