SEC staff had to make judgments in some limited cases as to whether certain securities held in prime money market funds were 

issued by a specific bank. The banks were then grouped by country based on location of their global headquarters. In general, the 

calculations include Asset Backed CP sponsored by a bank and all repos with that bank as counterparty. If identifiable with a specific 

bank, money market tranches of ABS are included in the calculation. Securities guaranteed, but not issued by, bank-related entities

Euro-zone is a subset of Europe and Euro-zone values are also included in totals for Europe.

SEC staff had to make judgments in some limited cases as to whether certain securities held in prime money market funds were 

issued by a specific bank. The banks were then grouped by country based on location of their global headquarters. In general, the 

calculations include Asset Backed CP sponsored by a bank and all repos with that bank as counterparty. If identifiable with a specific 

bank, money market tranches of ABS are included in the calculation. Securities guaranteed, but not issued by, bank-related entities

are not included.
