ATB was scandalized in the late 1980s after clients such as Peter Pocklington's Gainers Foods defaulted on loans that were often granted for political reasons. In the 1990s, the government reformed ATB with the intention of transforming it into a competitive financial institution. In October 1997, ATB formally became a provincial crown corporation. It adopted the moniker ATB Financial in January 2002.
As of this writing, the current Progressive Conservative government under Ralph Klein is rumoured to be considering privatization of ATB. This is opposed by many of the Tories' political rivals, including a resurgent Social Credit.
ATB is not a chartered bank, and unlike other banks operating in Canada, ATB is regulated entirely by the Government of Alberta, under the authority of the Alberta Treasury Branches Act, Chapter A-37.9, 1997, and Treasury Branches Regulation 187/97.
As of 1997, ATB operates under a board of directors nominally appointed by the Lieutenant-Governor of Alberta, although in practice these appointments are done by the Premier of Alberta.
As of March 31, 2005 ATB reported assets of $15.4 billion, deposits of $13.8 billion, loans of $13.1 billion, equity of $1.15 billion, and a net income $187.3 million.
