(b)the starting date shall be that of the first drawdown;
(c)intervals between dates used in the calculations shall be expressed in years or in fractions of a year;
(d)a year is assumed to have 365 days (366 days for leap years), 52 weeks or 12 equal months;
(e)an equal month is assumed to have 30.41666 days (365/12) regardless of whether or not it is a leap year;
(f)the result of the calculation shall be expressed with an accuracy of at least one decimal place; if the figure at the following decimal place is greater than or equal to 5, the figure at that particular decimal place shall be increased by one;
(g)the equation can be rewritten as set out in sub-paragraph (h) using a single sum and the concept of flows (Ak), which will be positive or negative, either paid or received during periods l to n, expressed in years;
(h)the equation referred to in sub-paragraph (g) is—
S being the present balance of flows; if the aim is to maintain the equivalence of flows, the value will be zero.
