Calculation of total net cash outflow amount. As of the calculation date, a Board-regulated institution's total net cash outflow amount equals:

The sum of the outflow amounts calculated under § 249.32(a) through (l); minus

The lesser of:

The sum of the inflow amounts calculated under § 249.33(b) through (g); and

75 percent of the amount calculated under paragraph (a)(1) of this section; plus

The maturity mismatch add-on as calculated under paragraph (b) of this section.

Calculation of maturity mismatch add-on. (1) For purposes of this section:

The net cumulative maturity outflow amount for any of the 30 calendar days following the calculation date is equal to the sum of the outflow amounts for instruments or transactions identified in § 249.32(g), (h)(1), (h)(2), (h)(5), (j), (k), and (l) that have a maturity date prior to or on that calendar day minus the sum of the inflow amounts for instruments or transactions identified in § 249.33(c), (d), (e), and (f) that have a maturity date prior to or on that calendar day.

The net day 30 cumulative maturity outflow amount is equal to, as of the 30th day following the calculation date, the sum of the outflow amounts for instruments or transactions identified in § 249.32(g), (h)(1), (h)(2), (h)(5), (j), (k), and (l) that have a maturity date 30 calendar days or less from the calculation date minus the sum of the inflow amounts for instruments or transactions identified in § 249.33(c), (d), (e), and (f) that have a maturity date 30 calendar days or less from the calculation date.

As of the calculation date, a Board-regulated institution's maturity mismatch add-on is equal to:

The greater of:

0; and

The largest net cumulative maturity outflow amount as calculated under paragraph (b)(1)(i) of this section for any of the 30 calendar days following the calculation date; minus

The greater of:

0; and

The net day 30 cumulative maturity outflow amount as calculated under paragraph (b)(1)(ii) of this section.

Other than the transactions identified in § 249.32(h)(2), (h)(5), or (j) or § 249.33(d) or (f), the maturity of which is determined under § 249.31(a), transactions that have no maturity date are not included in the calculation of the maturity mismatch add-on.
