Before investing in a Note investors shouldcarefully read the offering documents to understand the potential risks. Some general risk considerations for Notes include, but are not limited to the following:  ■ The Notes are unsecured debt obligations of RBC. Investors are dependent on the ability of RBC to pay all amounts due on the Notes, and therefore they aresubject to RBC’s credit risk and to changes in the market’s view of the creditworthiness of RBC.  ■ Investors could lose some or all of their principal if there is a decline in the level of the underlying index.  ■ Notes are typically sold at par and include fees and costs such as commissions, hedging costs and projected profits of RBC or its affiliates. Therefore, theestimated initial value (EIV) of a Note on the issue date will be less than the issue price that an investor pays for the Note. Any EIV of a Note does not representRBC’s estimate of the future value of the Note, or any price for which an investor may be able to sell it.  ■ The Notes will not be listed on any securities exchange. RBC and its affiliates are not obligated to maintain a secondary market and may cease market-makingactivities at any time. Any secondary market may not provide significant liquidity or trade at prices advantageous to the investor.  ■ The return on the Notes may be lower than the return investors could earn on other investments during the same term. The return on the Notes may be lessthan the return investors could earn if it bought a conventional debt security of RBC.  ■ Investing in the Notes is not the same as owning the components of the underlying index or a security directly linked to the underlying index or its components.  ■ The activities of RBC or its affiliates may conflict with investor’s interests and may adversely affect the value of the Notes. Also an affiliate of RBC will serve asthe calculation agent for the Notes who will exercise its judgment when performing its functions. Since the decisions the calculation agent makes will affectthe payments on the notes, the calculation agent may have a conflict of interest with respect to such decisions.  ■ Many economic and market factors will influence the value of the Notes.  ■ Significant aspects of the tax treatment of Notes may be complex and uncertain. Investors should consult with their tax advisor before investing in any Notesto determine the effects of their individual circumstances.  ■ The Notes have complex features and may not be suitable for all investors.  rbccm.com  (1) US$109 billion, as of July 31, 2017, per International Financial Reporting Standards (IFRS) (2) As of July 31, 2017 (3) A credit rating reflects thecreditworthiness of RBC is not a recommendation to buy, sell or hold the notes, and may be subject to revision or withdrawal at any time by the assigning ratingorganization.
