 determined for the applicable interest period, by a factor resulting from the day count convention that applies with respect to such determination. The factor resulting from the day count convention will be, if so specified in the applicable prospectus supplement, one of the following, or may be any other convention set forth in the applicable prospectus supplement:

| ● |     | a factor based on a 360-day year of twelve                                                               
 30-day months if the day count convention specified in the applicable prospectus supplement is “30/360”; |

| ● |     | a factor equal to the actual number of days in the relevant period divided by 360 if the day count convention 
 specified in the applicable prospectus supplement is “Actual/360”;                                            |

| ● |     | a factor equal to the actual number of days in the relevant period divided by 365, or if any portion of that                                                                                                                                    
 relevant period falls in a leap year, the sum of (A) the actual number of days in that portion of the relevant period falling in a leap year divided by 366 and (B) the actual number of days in that portion of the relevant period falling in 
 a non-leap year divided by 365, if the day count convention specified in the applicable prospectus supplement is “Actual/Actual”; or                                                                                                            |

| ● |     | a factor equal to the actual number of days in the relevant period divided by 365, if the day count convention 
 specified in the applicable prospectus supplement is “Actual/365 (Fixed).”                                     |

If no day count convention is specified in the applicable prospectus supplement, the factor resulting from the day count convention will be:

| ● |     | Actual/360, in the case of Compounded SOFR notes, EURIBOR debt securities, federal funds (effective) rate debt 
 securities and prime rate debt securities; and                                                                 |

| ● |     | Actual/Actual in the case of Treasury rate debt securities and CMT rate debt securities. |
