 Bank of New York Mellon, which currently acts as the clearing bank for the tri-party
repo market, as well as general collateral finance repo transaction data and data on bilateral U.S. Treasury repo transactions cleared through the FICC’s delivery-versus-payment service.

FRBNY states that it obtains information from DTCC Solutions LLC, an affiliate of DTCC. FRBNY currently publishes SOFR daily on its website.
FRBNY states on its publication page for SOFR that use of SOFR is subject to important disclaimers, limitations and indemnification obligations, including that FRBNY may alter the methods of calculation, publication schedule, rate revision practices
or availability of SOFR at any time without notice.

On July 29, 2021, the Alternative Reference Rates Committee (the
“ARRC”) convened by the Federal Reserve and FRBNY formally recommended the use of the CME Group’s computation of forward-looking SOFR term rates, which are calculated by the CME Group based on SOFR futures. It is currently
anticipated that Three-Month Term SOFR, for purposes of the Notes, will be based on the CME Group’s forward-looking SOFR term rates with a tenor of three months. FRBNY started publishing SOFR in April 2018. FRBNY has also started publishing
historical indicative SOFRs dating back to 2014, although such historical indicative data inherently involves assumptions, estimates and approximations. Investors should not rely on such historical indicative data or on any historical changes or
trends in SOFR as an indicator of the future performance of SOFR.

SOFR may be more volatile than other benchmark or market rates.

Since the initial publication of SOFR, daily changes in the rate have, on occasion, been more volatile than daily changes in comparable
benchmark or market rates, and SOFR over time may bear little or no relation to the historical actual or historical indicative data. In addition, the return on and value of the Notes may fluctuate more than floating rate securities that are linked
to other rates.

Changes in SOFR could adversely affect holders of the Notes.

Because SOFR is published by FRBNY based on data received from other sources, we have no control over its determination, calculation or
publication. There is no assurance 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 is changed, that change may
result in a
