This item represents the fair value on the entity's balance sheet of its investment in common stock of another entity in which we own less than 20 percent of an entity's common stock and do not provide significant influence over them. Due to the short-term nature of these investments, they are accounted for similar to a trading investment as unrealized gains and losses are immediately recognized in earnings.
