In order to avoid any conflict of interest between a bank and its statutory auditors, regular consultants and lawyers, the Central Bank instructs banks not to incur any exposure to such parties. In this context, a 'regular' consultant or lawyer means any person or firm who is employed on a regular basis either under a 'retainer agreement' for a specified period or under a more general 'understanding' according to which the bank would make use of the services offered by such persons or firms for most of its needs or cases.
