Invesco BulletShares 2023 Corporate Bond ETF

† Credit ratings are assigned by Nationally Recognized Statistical Rating Organizations based on assessment of the credit worthiness of the underlying bond issuers. The ratings range from AAA (highest) to D (lowest) and are subject to change. Not rated indicates the debtor was not rated, and should not be interpreted as indicating low quality. Futures and other derivatives are not eligible for assigned credit ratings by any NRSRO and are excluded from quality allocations. For more information on rating methodologies, please visit the following NRSRO websites: standardandpoors.com and select "Understanding Ratings" under Rating Resources and moodys.com and select "Rating Methodologies" under Research and Ratings.

There are risks involved with investing in ETFs, including possible loss of money. Shares are not actively managed and are subject to risks similar to those of stocks, including those regarding short selling and margin maintenance requirements. Ordinary brokerage commissions apply. The Fund's return may not match the return of the Underlying Index. The Fund is subject to certain other risks. Please see the current prospectus for more information regarding the risk associated with an investment in the Fund.

Investments focused in a particular sector, such as financials, are subject to greater risk, and are more greatly impacted by market volatility, than more diversified investments.

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

During the final year of the Fund's operations, as the bonds mature and the portfolio transitions to cash and cash equivalents, the Fund's yield will generally tend to move toward the yield of cash and cash equivalents and thus may be lower than the yields of the bonds previously held by the Fund and/or bonds in the market. If interest rates fall, it is possible that issuers of callable securities will call or prepay their securities before maturity, causing the Fund to reinvest proceeds in securities bearing lower interest rates and reducing the Fund's income and distributions.

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

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

Income generated from the Fund is based primarily on prevailing interest rates, which can vary widely over the short- and long-term. If interest rates drop, the Fund's income may drop as well. During periods of rising interest rates, an issuer may exercise its right to pay principal on an obligation later than expected, resulting in a decrease in the value of the obligation and in a decline in the Fund's income.

An issuer's ability to prepay principal prior to maturity can limit the Fund's potential gains. Prepayments may require the Fund to replace the loan or debt security with a lower yielding security, adversely affecting the Fund's yield.

The Fund currently intends to effect creations and redemptions principally for cash, rather than principally in-kind because of the nature of the Fund's investments. As such, investments in the Fund may be less tax efficient than investments in ETFs that create and redeem in-kind.

Unlike a direct investment in bonds, the Fund's income distributions will vary over time and the breakdown of returns between Fund distributions and liquidation proceeds are not predictable at the time of investment. For example, at times the Fund may make distributions at a greater (or lesser) rate than the coupon payments received, which will result in the Fund returning a lesser (or greater) amount on liquidation than would otherwise be the case. The rate of Fund distribution payments may affect the tax characterization of returns, and the amount received as liquidation proceeds upon Fund termination may result in a gain or loss for tax purposes.

During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value its holdings becomes more difficult and the judgment of the Sub-Adviser may play a greater role in the valuation of the Fund's holdings due to reduced availability of reliable objective pricing data.

The Fund's use of a representative sampling approach will result in its holding a smaller number of securities than are in the underlying Index, and may be subject to greater volatility.
