Electronic Back Office Transaction, is a two staged message process for agreeing the closing advice and settlement data related to an insurance transaction. The Technical Account (TA) is generated typically by a (re)insurance broker and then sent to a carrier of risk. The message can be queried till the data is correct and then unconditionally accepted. The second stage is agreeing the Financial Account (FA), which is a batch of agreed TA’s all related to the same entity and of the same currency, replicating the functionality of a weekly/monthly statement. It is only at the point that when the FA is agreed will the money exchange hands. This eradicates unallocated cash and allows the reconciliation process to happen far sooner after the risk has been bound.
