D1 is the first calendar day, expressed as a number, of the interest period,
unless such number would be 31, in which caseD1 will be 30; and
D2 is the calendar day, expressed as a number, immediately
following the last day included in the interest period, unless such number would be 31 and D1 is greater than 29, in which case D2 will be 30.
If 30E/360 or Eurobond Basis is specified, the accrued interest factor will be the number of days in the interest period in respect of
which payment is being made divided by 360, calculated on a formula basis as follows:
Day Count Fraction = [360 x (Y22- Y1)] + [30 x (M22- M1)] + (D22- D1)
360
where:
Y1 is the year, expressed as a number, in which the first day of the interest period falls;
Y2 is the year, expressed as a number, in which the day immediately following the last day included in the interest period falls;
M1 is the calendar month, expressed as a number, in which the first day of the interest period falls;
M2 is the calendar month, expressed as a number, in which the day immediately following the last day included in the interest
period falls;
D1 is the first calendar day, expressed as a number, of the interest period, unless such number would be 31, in
which caseD1 will be 30; and
D2 is the calendar day, expressed as a number, immediately following the last day included in the
interest period, unless such number would be 31, in which case D2 will be 30.
If 30E/360 (ISDA) is specified, the accrued interest
factor will be the number of days in the interest period in respect of which payment is being made divided by 360, calculated on a formula basis as follows:
Day Count Fraction = [360 x (Y22- Y1)] + [30 x (M22- M1)] + (D22- D1)
360
where:
Y1 is the
year, expressed as a number, in which the first day of the interest period falls;
Y2 is the year, expressed as a number, in
which the day immediately following the last day included in the interest period falls;
M1 is the calendar month, expressed as
a number, in which the first day of the interest period falls;
M2 is the calendar month, expressed as a number, in which the
day immediately following the last day included in the interest period falls;
D1 is the first calendar day, expressed as a
number, of the interest period, unless (i) that day is the last day of February or (ii) such number would be 31, in which case D1 will be 30; and D2 is the calendar day, expressed as a number, immediately following the last day
included in the interest period, unless (i) that day is the last day of February but not the maturity date or (ii) such number would be 31, in which case D2 will be 30.
