The Blended Benchmark consists of the following: PHLX Utility Sector Index (50%) and Alerian MLP Index (50%). The Blended Benchmark reflects the diverse allocation of companies engaged in the energy infrastructure sector in the Fund’s portfolio. The indices do not charge management fees or brokerage expenses, and no such fees or expenses were deducted from the performance shown. Indexes are unmanaged and an investor cannot invest directly in an index. The Blended Benchmark returns are calculated by using the monthly return of the two indices during each period shown above. At the beginning of each month the two indices are rebalanced to a 50-50 ratio to account for divergence from that ratio that occurred during the course of each month. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.
[2] The Blended Benchmark consists of a 70/20/10 blend of the MVIS U.S. Business Development Companies Index, the FTSE NARIET Mortgage REIT Index and the S&P SmallCap Financials Index. The Blended Benchmark returns are calculated by using the monthly return of the three indices during each period shown above. At the beginning of each month, the three indices are rebalanced, to account for divergence from that ratio that occurred during the course of each month to the ratios noted above. The monthly returns are then compounded for each period shown above, giving the performance for the Blended Benchmark for each period shown above.
