The provincial government of Alberta, Canada, has terminated the entire board of the C$168.9 billion ($124.5 billion) Alberta Investment Management Corp., Edmonton, citing underperformance issues and rising costs.

The province says the move comes 'after years of AIMCo consistently failing to meet its mandated benchmark returns.' For now, Finance Minister Nate Horner has been appointed the sole director and chair for AIMCo.

AIMCo has seen significant increases in operating costs and fees alongside returns on investment that have not corresponded with the cost increases, the province added.

The news release said Alberta’s government plans to appoint a new board chair within 30 days. In the interim, Horner has been appointed the sole director and chair for AIMCo. All previous board member appointments have been “rescinded” and a new board is to be established after a permanent chair is named, according to the release.

Alberta Investment Management Corp.’s entire board was sacked by the provincial government, which said the money manager has increased compensation and staff but hasn’t produced acceptable returns.  Alberta Finance Minister Nate Horner will temporarily become the fund manager’s chairman and sole director as the government of the Canadian province overhauls the firm.
