BlackRock TCP Capital Corp. (NASDAQ:TCPC) is a well-managed business development company that has produced a high degree of excess dividend coverage in the last couple of years. The portfolio is well-diversified and management has handed investors a 13% increase in the regular dividend in the last year. Though I consider the discount to net asset value as another positive, the business development company is too heavily invested in floating-rate loans which suggests a drop in net investment income in a lower-rate environment as well as a potentially lower margin of dividend safety.
