PID offers exposure to equities with growing dividends that are determined as Dividend Achievers. In addition to its requirement for five years of dividend growth, the fund gets its exposure to non-US international firms that trade in the United States and the London Stock Exchange, which includes ADRs, GDRs and common stocks. The index is rebalanced quarterly starting every February based on the trailing 12-month dividend yield of each security as compared to the dividend yield of all its components.
