Invesco Fundamental Investment Grade Corporate Bond ETF(AMEX:PFIG)

PFIG selects and weights its bonds using bottom-up fundamental metrics. The fund invests in investment-grade corporate bonds rated BBB/Baa and higher by Moody's or S&P. The starting universe begins with all US-based publicly traded corporations that are scored by RAFI using the four fundamental factors (sales, dividends, cash flow and return on assets). Only companies with positive scores are selected. There are two distinct maturity cells (15 years and 510 years) that the index employs that allow up to two bonds per issuer. The issues are weighted proportionally to a companys RAFI score. The index is reconstituted monthly and rebalanced annually for new RAFI scores.
