I am needing help on how to answer the following discussion topic and how it relates to HTM securities, trading securities, and AFS securities and their financial statements amid the downturn of the stocks and bonds market during the COVID pandemic and the Fed dropping the interest rate.

Explain the expected impact of the downturn in the stock and bond markets on the financial statements of a corporation that holds investments in listed stocks and bonds. Your answer should also consider the impact of changing stock and bond values on the Income statement, balance sheet, and OCI. Also include fair value adjustments.
