SELECTED RISK CONSIDERATIONS

The Notes involve risks not associated with an investment in ordinary floating rate notes. We urge you to consult your investment, legal, tax, accounting and other advisers before you invest in the Notes. Some of the risks that apply to an investment in the Notes are summarized below, but we urge you to read also the “Risk Factors” sections of the accompanying prospectus, prospectus supplement and product supplement. You should not purchase the Notes unless you understand and can bear the risks of investing in the Notes.

Risks Relating to the Terms and Structure of the Notes

· The Interest Rate on the Notes Is a Floating Rate and May Be Equal to the Coupon Floor — Interest payable on the Notes will be based on, in part, on the Reference Rate for the relevant Interest Period. The Reference Rate could decline significantly, including to a rate equal to or less than zero. If the Interest Rate for any Interest Period is equal to the Coupon Floor, no interest will be payable with respect to that Interest Period. Accordingly, you may not receive any interest payments on the Notes.

· The Interest Rate on the Notes Will Be Limited to the Coupon Cap — Interest payable on the Notes will not exceed the Coupon Cap. Accordingly, interest payable on the Notes may be less than interest payable on an investment directly linked to the Reference Rate without any cap.

· Payments on the Notes Are Subject to Our Credit Risk, and Market Perceptions about Our Creditworthiness May Adversely Affect the Market Value of the Notes — The Notes are our senior unsecured debt securities, and your receipt of any amounts due on the Notes is dependent upon our ability to pay our obligations as they come due. If we were to default on our payment obligations, you may not receive any amounts owed to you under the Notes and you could lose your entire investment. In addition, any negative changes in market perceptions about our creditworthiness may adversely affect the market value of the Notes.

Risks Relating to Conflicts of Interest

· RBCCM’s Role as Calculation Agent May Create Conflicts of Interest — As Calculation Agent, our affiliate, RBCCM, will determine any levels of the Reference Rate and make any other determinations necessary to calculate any payments on the Notes. In making these determinations, the Calculation Agent may be required to make discretionary judgments, including those described under “— Risks Relating to the Reference Rate” below. In making these discretionary judgments, the economic interests of the Calculation Agent are potentially adverse to your interests as an investor in the Notes, and any of these determinations may adversely affect any payments on the Notes. The Calculation Agent will have no obligation to consider your interests as an investor in the Notes in making any determinations with respect to the Notes.

Risks Relating to the Reference Rate

· The Secured Overnight Financing Rate Is a Relatively New Reference Rate and its Composition and Characteristics Are Not the Same as LIBOR — The publication of SOFR began in April 2018, and, therefore, it has a limited history. In addition, the future performance of SOFR cannot be predicted based on the limited historical performance. The level of SOFR during the term of the Notes may bear little or no relation to the historical actual or historical indicative SOFR data. Prior observed patterns, if any, in the behavior of market variables and their relation to SOFR, such as correlations, may change in the future. While some pre-publication historical data has been released by the Federal Reserve Bank of New York, production of such historical indicative SOFR data inherently involves assumptions, estimates and approximations. No future performance of SOFR may be inferred from any of the historical actual or historical indicative SOFR data. Hypothetical or historical performance data are not indicative of, and have no bearing on, the potential performance of SOFR.

The composition and characteristics of SOFR are not the same as those of LIBOR, and SOFR is fundamentally different from LIBOR for two key reasons. First, SOFR is a secured rate, while LIBOR is an unsecured rate. Second, SOFR is an overnight rate, while LIBOR is a forward-looking rate that represents interbank funding over different maturities (e.g.,

P-4 RBC Capital Markets, LLC

three months). As a result, there can be no assurance that SOFR (including SOFR, compounded as described in this document) will perform in the same way as LIBOR would have at any time, including, without limitation, as a result of changes in interest and yield rates in the market, market volatility or global or regional economic, financial, political, regulatory, judicial or other events. For example, since publication of SOFR began in April 2018, daily changes in SOFR have, on occasion, been more volatile than daily changes in comparable benchmark or other market rates. For the same reasons, SOFR is not expected to be a comparable substitute, successor or replacement for LIBOR.

· The Reference Rate Will Be Affected by a Number of Factors and May Be Volatile — Many factors may affect the Reference Rate including, but not limited to:

· supply and demand for overnight U.S. Treasury repurchase agreements;

· sentiment regarding underlying strength in the U.S. and global economies;

· expectations regarding the level of price inflation;

· sentiment regarding credit quality in the U.S. and global credit markets;

· central bank policy regarding interest rates;

· inflation and expectations concerning inflation;

· performance of capital markets; and

· any statements from public government officials regarding the cessation of the Reference Rate.

These and other factors may have a negative impact on the payments on the Notes and on the value of the Notes in the secondary market. Additionally, these factors may cause the Reference Rate to be volatile, and volatility of the Reference Rate may adversely affect your return on the Notes.

· The Reference Rate with Respect to a Particular Interest Period Will Be Capable of Being Determined Only Near the End of the Relevant Interest Period — The Reference Rate is applicable to a particular Interest Period and, therefore, the amount of interest payable with respect to that Interest Period cannot be determined until near the end of that Interest Period. As a result, you will not know the amount of interest payable with respect to a particular Interest Period until shortly prior to the related Interest Payment Date, and it may be difficult for you to reliably estimate the amount of interest that will be payable on that Interest Payment Date.

· SOFR May Be Modified or Discontinued and the Notes May Bear Interest by Reference to a Rate Other than SOFR, which Could Adversely Affect the Value of the Notes — SOFR is published by the Federal Reserve Bank of New York based on data received by it from sources other than us, and we have no control over its methods of calculation, publication schedule, rate revision practices or availability of SOFR at any time. There can be no guarantee, particularly given its relatively recent introduction, that SOFR will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Notes. If the manner in which SOFR is calculated, including the manner in which SOFR is calculated, is changed, that change may result in a reduction in the amount of interest payable on the Notes and the trading prices of the Notes. In addition, the Federal Reserve Bank of New York may withdraw, modify or amend the published SOFR data in its sole discretion and without notice. The interest rate for any Interest Period will not be adjusted for any modifications or amendments to SOFR data that the Federal Reserve Bank of New York may publish after the interest rate for that Interest Period has been determined.

· Uncertainty as to Some of the Potential Benchmark Replacements and any Benchmark Replacement Conforming Changes We Make May Adversely Affect the Return on and the Market Value of the Notes — If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred in respect of the Reference Rate, then the Interest Rate will no longer be determined by reference to compounded SOFR, but instead will be determined by reference to a different rate, plus a spread adjustment, which we refer to as a “Benchmark Replacement,” as further described below.

P-5 RBC Capital Markets, LLC

Collared Floating Rate Notes

If a particular Benchmark Replacement or Benchmark Replacement Adjustment cannot be determined, then the next-available Benchmark Replacement or Benchmark Replacement Adjustment will apply. These replacement rates and adjustments may be selected, recommended or formulated by (i) the Relevant Governmental Body (such as the Alternative Reference Rates Committee), (ii) the International Swaps and Derivatives Association (“ISDA”) or (iii) in certain circumstances, the Calculation Agent. In addition, the terms of the Notes expressly authorize the Calculation Agent to make Benchmark Replacement Conforming Changes with respect to, among other things, changes to the definition of “Interest Period,” the methodology, timing and frequency of determining rates and making payments of interest and other administrative matters. The determination of a Benchmark Replacement, the calculation of the interest rate on the Notes by reference to a Benchmark Replacement (including the application of a Benchmark Replacement Adjustment), any implementation of Benchmark Replacement Conforming Changes and any other determinations, decisions or elections that may be made under the terms of the Notes in connection with a Benchmark Transition Event, could adversely affect the value of the Notes, the return on the Notes and the price at which you can sell such Notes.

In addition, (i) the composition and characteristics of the Benchmark Replacement will not be the same as those of the Reference Rate, the Benchmark Replacement may not be the economic equivalent of the Reference Rate, there can be no assurance that the Benchmark Replacement will perform in the same way as the Reference Rate would have at any time and there is no guarantee that the Benchmark Replacement will be a comparable substitute for the Reference Rate (each of which means that a Benchmark Transition Event could adversely affect the value of the Notes, the return on the Notes and the price at which you may sell the Notes), (ii) any failure of the Benchmark Replacement to gain market acceptance could adversely affect the Notes, (iii) the Benchmark Replacement may have a very limited history and the future performance of the Benchmark Replacement may not be predicted based on historical performance, (iv) the secondary trading market for Notes linked to the Benchmark Replacement may be limited and (v) the administrator of the Benchmark Replacement may make changes that could change the value of the Benchmark Replacement or discontinue the Benchmark Replacement and has no obligation to consider your interests in doing so.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

You should review carefully the section in the accompanying product supplement entitled “United States Federal Income Tax Considerations,” focusing particularly on the section entitled “—Tax Consequences to U.S. Holders—Notes Treated as Debt Instruments—Notes Treated as Variable Rate Debt Instruments.” The following discussion, when read in combination with “United States Federal Income Tax Considerations” in the accompanying product supplement, constitutes the full opinion of our counsel, Davis Polk & Wardwell LLP, regarding the material U.S. federal income tax consequences of owning and disposing of the Notes. This discussion assumes that you purchased the Notes for cash in the original issuance at the stated issue price and does not address other circumstances specific to you. In the opinion of our counsel, which is based on representations provided by us, it is reasonable to treat the Notes for U.S. federal income tax purposes as Single Rate VRDIs (as defined in the accompanying product supplement) that are issued without original issue discount. You should consult your tax adviser regarding the U.S. federal income tax consequences of an investment in the Notes in your particular circumstances, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.
