The rule in plain words

The value of this exposure must be greater than or equal to zero.

In Leverage ratio calculation (LRCalc) (LV47.00.00.01): every value in "Total exposure measure including claims on central banks - using a fully phased-in definition of tier 1 capital (leverage)" (row 0281), "Total exposure measure including claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0282), "Total exposure measure excluding claims on central banks - using a fully phased-in definition of tier 1 capital (leverage)" (row 0290) and "Total exposure measure excluding claims on central banks - using a transitional definition of tier 1 capital (leverage)" (row 0300) in "Quarter Low (LREQ firms only)" (column 0030) and "Quarter high (LREQ firms only)" (column 0040) must be zero or more.

  1. 01Open the table below and find the cells the rule reads.
  2. 02Look for a value below zero in these cells, such as an amount entered as a negative number.
