PGF delivers a concentrated portfolio of exclusively financial-sector preferred securities. To be eligible for inclusion in the underlying index, such securities must be USD denominated, have no final maturity date, and whose payments are qualified dividend income under the US tax code. Qualifying securities must also be listed on the NASDAQ or NYSE. Its financials-only focus sets PGF apart: the fund takes an already-dominant sector and embraces it fully. Like its peers, PGF holds both investment- and non-investment-grade securities. The Index is rebalanced on the last calendar day of each month. Prior to June 30, 2021, the fund tracked the Wells Fargo Hybrid and Preferred Securities Financial Index.
