Invesco Core Plus Bond Portfolio

Risks of the Underlying Holding

An issuer may be unable to meet interest and/or principal payments, thereby causing its instruments to decrease in value and lowering the issuer's credit rating.

Interest rate risk refers to the risk that bond prices generally fall as interest rates rise and vice versa.

The risks of investing in securities of foreign issuers, including emerging market issuers, can include fluctuations in foreign currencies, political and economic instability, and foreign taxation issues.

Junk bonds involve a greater risk of default or price changes due to changes in the issuer's credit quality. The values of junk bonds fluctuate more than those of high quality bonds and can decline significantly over short time periods.

Mortgage- and asset-backed securities are subject to prepayment or call risk, which is the risk that the borrower's payments may be received earlier or later than expected due to changes in prepayment rates on underlying loans. Securities may be prepaid at a price less than the original purchase value.

Derivatives may be more volatile and less liquid than traditional investments and are subject to market, interest rate, credit, leverage, counterparty and management risks. An investment in a derivative could lose more than the cash amount invested.

The Fund may invest in privately issued securities, including 144A securities which are restricted (i.e. not publicly traded). The liquidity market for Rule 144A securities may vary, as a result, delay or difficulty in selling such securities may result in a loss to the Fund.

The Fund invests in financial instruments that use the London Interbank Offered Rate (“LIBOR”) as a reference or benchmark rate for variable interest rate calculations. LIBOR will be phased out by the end of 2021, and it's anticipated that LIBOR will cease to be published after that time. The uncertainty on the effects of the LIBOR transition process, therefore any impact of the LIBOR transition on the Fund or its investments cannot yet be determined. There is no assurance an alternative rate will be similar to, produce the same value or economic equivalence or instruments using the rate will have the same volume or liquidity as LIBOR. Any effects of LIBOR transition and the adoption of alternative rates could result in losses to the Fund.
