CALGARY, ALBERTA--(Marketwire - Sept. 20, 2012) - Superior Plus Corp. (TSX:SPB)

Since the beginning of 2010, the Canada Revenue Agency ("CRA") has requested information relating to Superior's conversion transaction which occurred on December 31, 2008 (the "Conversion") and Superior has responded to such requests and engaged in extensive discussions, including detailed settlement discussions, with representatives of the CRA. The CRA has now advised Superior that the CRA believes it does not have authority to settle the matter in this context. If the CRA does not change its current position, the CRA has advised Superior that it should expect that the matter will be directed back to the local tax office which is expected, in the normal course, to issue a proposal letter challenging the tax consequences of the Conversion. During the discussions, the CRA indicated that the general anti-avoidance rule of the Income Tax Act (Canada) is available to the CRA as a basis upon which to challenge the tax consequences of the Conversion.

Based on these developments, unless the CRA subsequently determines it has the authority to settle this matter, Superior expects to receive a proposal letter and thereafter a notice of reassessment challenging the tax consequences of the Conversion. Superior remains confident in the appropriateness of its tax filing position and the expected tax consequences of the Conversion and intends to vigorously defend such position if and when a proposal letter or notice of reassessment is received from the CRA. Superior strongly believes that the general anti-avoidance rule does not apply to the Conversion and intends to file its future tax returns on a basis consistent with its view of the outcome of the Conversion.

If Superior receives such a reassessment, in order to appeal it, Superior will be required to make a payment of 50% of the taxes the CRA claims are owed for such years. Based on Superior's 2009, 2010 and 2011 taxation years, that 50% amount is approximately $15 million. Superior would also be required to make a payment of 50% of the taxes the CRA claims are owed in any future tax year if the CRA issues a similar notice of reassessment for such years and Superior appeals it. If Superior is ultimately successful in defending its position, such payments plus applicable interest, will be refunded to Superior. If the CRA is successful, Superior will be required to pay the balance of the taxes claimed plus applicable interest and penalties.

Superior's 2012 financial outlook as provided at the second quarter of 2012 of adjusted operating cash flow ("AOCF") per share of $1.45 to $1.80 per share is not currently impacted by the potential reassessment as any interim tax payments made by Superior will be recorded to the balance sheet and will not impact either AOCF or net earnings.

Based on the midpoint of Superior's current 2012 financial outlook of AOCF per share of $1.63, if the tax pools from the Conversion were not available to Superior, the impact would be an increase to cash income taxes of approximately $0.20 per share. This equates to a calculated income tax rate of 12% based on the midpoint of Superior's 2012 financial outlook. Superior anticipates that the impact in 2013, if such tax pools were not available, would result in a calculated income tax rate similar to 2012. As previously stated, Superior intends to file its future income tax returns on a basis consistent with its view of the outcome of the Conversion.

Luc Desjardins, President and Chief Executive Officer, stated "We remain highly confident with our position based on the due diligence performed before the transaction was completed and changes to the Income Tax Act subsequent to Superior completing its transaction. Superior will continue to remain focused on improving the day-to-day operations of our businesses to ensure the success of our business transformation project."

Additionally, Superior is pleased to announce that it has received a payment of $15.8 million from TransCanada as a settlement in relation to Superior's Power Purchase Agreement ("PPA") with TransCanada due to the final arbitration settlement between TransCanada and TransAlta. A one-time gain of $12.5 million, representing the gross settlement net of certain settlement costs, will be recognized in the third quarter of 2012.
