FREDERICTON -- New Brunswick's auditor general says she intends to find out what happened to $70 million in taxpayer funding for the now-bankrupt Atcon Group of companies.

Kim MacPherson made the announcement Tuesday as she released two volumes of audit performance reports before the legislature's public accounts committee.

MacPherson issued a report on Atcon in March. In it she said the former Liberal government of then-premier Shawn Graham provided $50 million in loan guarantees in 2009 despite recommendations by senior staff to reject the assistance request.

Atcon filed for creditor protection in 2010, leaving taxpayers on the hook for nearly $70 million, MacPherson concluded at the time.

"I remained concerned," MacPherson told the committee.

"My office continues to receive numerous phone calls, emails, letters, meeting requests over this file."

MacPherson said she is in the process of gaining access to Atcon's books and records, which are currently in the custody of a court-appointed receiver.

She said she has informed the government that she will need more money and staff to pursue the work in 2016.

"I intend to table an independent report responding to the unanswered questions, such as where did $70 million of taxpayers money go?"

MacPherson said the government has indicated that it supports her.

Tuesday's report also found the New Brunswick Lotteries and Gaming Corp. has overpaid the province's seven First Nations $14 million since 2002 because of calculation errors on video lottery terminals.

MacPherson said although the problem was found in 2013, the corporation is continuing to make the overpayments at a rate of $172,000 per month.

"There's no authority under ... legislation to make these overpayments," she said.

MacPherson said First Nations were advised in August that the calculation would be amended, but they have since challenged the new calculation and requested a dispute resolution process.

"As of today it has not been resolved," said MacPherson.

The report said there are 300 unauthorized VLTs throughout the province and the amount of lost revenue from them can't be quantified.
