Investment Tax Credits

The Company is eligible to claim Canadian federal and provincial ITCs for eligible scientific research and development expenditures. The Company records ITCs based on management's best estimates of the amount to be recovered and ITCs claimed are subject to audit by the taxation authorities and accordingly, may vary by a material amount.

The Company recorded provincial refundable ITCs as a reduction of research and development expenditures of $0.9 million and $1.7 million (including a $1.1 million favorable adjustment resulting from a statutory audit), for the years ended December 31, 2013 and 2012, respectively.

The Company's non-refundable Canadian federal ITCs amount to $4.1 million and $3.1 million at December 31, 2013 and 2012, respectively, and relate to scientific research and development expenditures, which may be utilized to reduce Canadian federal income taxes payable in future years. The benefits of the non-refundable Canadian federal ITCs have not been recognized in the financial statements and will be recorded as reduction of tax expense when realized.
