1. The document discusses different types of investments and the accounting methods used for each. It covers trading securities, available-for-sale securities, held-to-maturity securities, and equity method investments.
2. For available-for-sale securities, changes in fair value are recorded in other comprehensive income rather than net income. Held-to-maturity investments use the amortized cost approach.
3. The equity method is used when an investor has significant influence over an investee, usually through 20-50% ownership. It addresses accounting for investments in bonds and consolidating subsidiaries.
