The Trust is managed by ING Investments, LLC and sub-advised by ING Investment Management Co., and its shares are distributed by ING Investments Distributor, LLC. The adviser, the sub-adviser and the distributor are indirect, wholly-owned subsidiaries of Amsterdam-based ING Groep N.V. (NYSE: ING), one of the world’s leading financial services companies with operations in over 65 countries. The Trust’s operations are based in Scottsdale, Arizona.Distribution Rates are calculated by annualizing dividends declared during the period ( i.e., divide the monthly dividend amount by the number of days in the related month and multiply by the number of days in the fiscal year) and then dividing the resulting annualized dividend by the month-ending NAV (in the case of NAV) or the month-end closing price on the NYSE composite (in the case of Market). The distribution rate is based solely on actual dividends and distributions, which are made at the discretion of management. The distribution rate may or may not include all investment income, and ordinarily will not include capital gains. Past performance is no assurance of future results. Investment return and principal value of an investment in the Trust will fluctuate. Shares, when sold, may be worth more or less than their original cost. Principal Risk Factor(s): The Trust invests primarily in below investment grade, floating rate senior loans that carry a higher than normal risk that borrowers may default in the timely payment of principal and interest on their loans, which would likely cause the value of the Trust’s Common Shares to decrease. Changes in short-term market interest rates will directly affect the yield on the Trust’s Common Shares. If such rates fall, the Trust’s yield will also fall. If interest rate spreads on Trust’s loans decline in general, the yield on the Trust’s loans will fall and the value of the Trust’s loans may decrease. When short-term market interest rates rise, because of the lag between changes in such short term rates and the resetting of the floating rates on loans in the Trust’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Because of the limited secondary market for floating rate senior bank loans, the Trust’s ability to sell its loans in a timely fashion and/or at a favorable price may be limited. An increase in the demand for loans may adversely affect the rate of interest payable on new loans acquired by the Trust, and it may also increase the price of loans purchased by the Trust in the secondary market. A decrease in the demand for loans may adversely affect the price of loans in the Trust’s portfolio, which would cause the Trust’s NAV to decrease. The Trust’s use of leverage through borrowings or issuance of preferred shares can adversely affect the yield on the Trust’s Common Shares. The Trust may invest up to 20% of its assets in loans to borrowers in countries outside of the U.S. and Canada. Investment in foreign borrowers involves special risks, including potentially less rigorous accounting requirements, differing legal systems and potential political, social and economic adversity. The Trust may invest up to 15% of its assets in loans that are denominated in certain foreign currencies, however, the Trust will engage in currency exchange transactions to seek to hedge, as closely as practicable, 100% of the economic impact to the Trust arising from foreign currency fluctuations. Other risks include but are not limited to: Borrowings; Preferred Shares; Diversification Risks; and Concentration Risks.
