(1) On May 10, 2017, Moody's downgraded the Baseline Credit Assessment (BCA), the long-term ratings and the Counterparty Risk
     Assessments (CRA) of the six DSIBs, including NBC, reflecting Moody's expectation of a more challenging operating environment for
     banks in Canada for the remainder of 2017 and beyond. The short term Prime-1 ratings of the Canadian banks were affirmed.
(2) On December 11, 2015, Standard & Poor's changed the trend on the senior debt of Canadian banks.
(3) On May 20, 2015, DBRS changed the trend on the senior and subordinated debt ratings of Canadian banks.
(4) On May 19, 2015, Fitch Ratings downgraded the Support Ratings (SRs) to "2" from "1" and revised the Support Ratings Floors (SRFs)
     to "BBB-" from "A-" for Canadian banks. The Long-term Issuer Default Ratings are all above the Support Rating Floors thus do not
     currently incorporate any government support, and reflect their standalone strengths only.

Credit ratings must not be construed as recommendations to purchase, sell or hold securities of the Bank. Ratings may not reflect the potential impact of all risks. Ratings may be revised or withdrawn at any time by the rating agencies.
