Context paragraphs:
International financial institutions: An international financial institution (IFI) is a financial institution that has been established (or chartered) by more than one country, and hence are subjects of international law.  Its owners or shareholders are generally national governments, although other international institutions and other organizations occasionally figure as shareholders.  The most prominent IFIs are creations of multiple nations, although some bilateral financial institutions (created by two countries) exist and are technically IFIs.  The best known IFIs were established after World War II to assist in the reconstruction of Europe and provide mechanisms for international cooperation in managing the global financial system.

Suspicious activity report: In financial regulation, a Suspicious Activity Report (SAR) or Suspicious Transaction Report (STR) is a report made by a financial institution about suspicious or potentially suspicious activity.  The criteria to decide when a report must be made varies from country to country but generally is any financial transaction that does not make sense to the financial institution, is unusual for that particular client or appears to be done only for the purpose of hiding or obfuscating a transaction.  The report is filed with that country's financial crime enforcement unit, which is typically a specialist agency designed to collect and analyse transactions and report these to relevant law enforcement units.  Front line staff in the financial institution have the responsibility to identify transactions that may be suspicious and these are reported to a designated person that is responsible for the reporting the transaction.  The financial institution is not allowed to inform the client or the parties to the transaction that a SAR has been lodged.

Concentration account: A concentration account is a sole account used for the internal purposes of a financial institution to facilitate the processing and settlement of multiple or individual customer transactions within the institution, usually on the same day.  Such accounts can lead to the concealment by financial institutions of transactions made by customers.  However section 325 of Title III of the USA PATRIOT Act banned their use for such purposes by prohibiting financial institutions from allowing clients to direct transactions that move their funds into, out of, or through the concentration accounts of the financial institution; and prohibit the financial institutions from informing clients about the existence of such accounts and disallows any disclosure that may allow a customer a way of identifying such accounts that the financial institution may use.  Section 325 also requires that financial institutions document and follow methods of identifying where the funds are for each customer in a concentration account that comingles funds belonging to one or more customers.

Bank account: A bank account is a financial account maintained by a financial institution for a customer.  A bank account can be a deposit account, a credit card account, a current account, or any other type of account offered by a financial institution, and represents the funds that a customer has entrusted to the financial institution and from which the customer can make withdrawals.  Alternatively, accounts may be loan accounts in which case the customer owes money to the financial institution.
