The Invesco Fundamental Investment Grade Corporate Bond ETF (PFIG) is an exchange-traded fund structured to track the performance of the RAFI Bonds US Investment Grade 1-10 Index. Typically, the Fund allocates at least 80% of its total assets to the securities comprising this benchmark. The underlying index is composed of U.S. dollar-denominated, investment-grade corporate bonds issued by publicly traded American companies. These bonds must qualify under specific SEC registration categories, including SEC-registered, Section 3(a)(2), or Rule 144A securities. For inclusion, bonds must also be non-convertible, non-exchangeable, and possess a fixed, non-zero coupon. The index's methodology, known as the Fundamental Index, was developed by Research Affiliates, LLC, with ALM Research Solutions, LLC responsible for its compilation and calculation. Instead of acquiring every security in the index, the Fund employs a sampling strategy to achieve its investment objectives. Both the Fund and its benchmark index undergo monthly rebalancing and an annual reconstitution, which occurs each March. As of August 31, 2025, Morningstar Inc. awarded the Fund an overall rating of 4 stars out of 163 funds. It also received 4 stars for the 3-year period (out of 163 funds), 4 stars for the 5-year period (out of 148 funds), and 3 stars for the 10-year period (out of 96 funds). Morningstar ratings are based on risk-adjusted returns, emphasizing consistent performance and accounting for variations in monthly performance, particularly downward movements. For comparison, open-end mutual funds and exchange-traded funds are grouped together. To receive a rating, a fund must have at least a three-year history. The overall rating is derived from a weighted average of the 3-, 5-, and 10-year metrics, where applicable, after accounting for fees and expenses but excluding sales charges. Morningstar's star distribution assigns five stars to the top 10% of funds, four stars to the next 22.5%, three stars to the subsequent 35%, two stars to the following 22.5%, and one star to the bottom 10%. These ratings are dynamic and subject to monthly changes. It's important to note that these ratings are proprietary to Morningstar; past performance offers no guarantee of future results. Also, had fees not been waived or expenses reimbursed, the Morningstar rating could have been lower, and ratings may differ for other share classes due to varying performance characteristics.
