ALTUS GROUP ANNOUNCES A NON-CASH INCOME TAX EXPENSE ADJUSTMENT

TORONTO, ONTARIO (January 9, 2012) - Altus Group Limited ("Altus") (TSX:AIF) today announced that it will record a non-cash adjustment to income tax expenses related to UK operations, for the
quarters ended March 31, 2011, June 30, 2011 and September 30, 2011, in the approximate amounts of $1.1
million, $0.3 million and $0.2 million, respectively. Although this will decrease comprehensive income
(loss) by the same amounts in the respective periods, Adjusted EBITDA for the company is unaffected and remains as previously reported.
"It was determined this non-cash adjustment was necessary to accurately reflect a legislative change with respect to the calculation of income as it relates to the Altus UK LLP entity," outlined Angelo Bartolini, CFO, Altus Group.
Deferred tax assets will be reduced by approximately $1.0 million, $1.3 million and $1.7 million as of March 31, 2011, June 30, 2011 and September 30, 2011, respectively. As a result, Altus will be adjusting its financial statements for the interim periods of 2011 to reflect these changes.
