INCOME TAXES [Text Block]

NOTE 12: INCOME TAXES

At July 31, 2013, the Company had U.S. and Canadian net operating loss carry-forwards of approximately $83.1 million and $6.2 million in Canadian dollars, respectively, that may be available to reduce future years’ taxable income. These carry-forwards will begin to expire, if not utilized, commencing in 2023. Future tax benefits which may arise as a result of these losses have not been recognized in these consolidated financial statements, as their realization has been determined not likely to occur and accordingly, the Company has recorded a full valuation allowance for the deferred tax asset relating to these tax loss carry-forwards.

The Company reviews its valuation allowance requirements on an annual basis based on projected future operations. When circumstances change resulting in a change in management’s judgement about the recoverability of future tax assets, the impact of the change on the valuation allowance will generally be reflected in current income.

A reconciliation of income tax computed at the federal and state statutory tax rates including the Company’s effective tax rate is as follows:

	Year Ended July 31,
	2013	2012	2011
Federal income tax provision rate	35.00%	35.00%	35.00%
State income tax provision rate,     net of federal income tax effect	0.10%	0.18%	0.15%
Total income tax provision rate	35.10%	35.18%	35.15%

The actual income tax provisions differ from the expected amounts calculated by applying the combined federal and state corporate income tax rates to the Company’s loss before income taxes. The components of these differences are as follows:

The Company has incurred taxable losses for all years since inception and accordingly, no provision for current income taxes has been recorded for the current or any prior fiscal year. During Fiscal 2013, the Company recorded a deferred income tax benefit of $10,753 (Fiscal 2012: $61,788 ; Fiscal 2011: $Nil) on the consolidated statements of operations.

As the criteria for recognizing future income tax assets have not been met due to the uncertainty of realization, a valuation allowance of 100% has been recorded for the current and prior years.

The Company’s U.S. net operating loss carry-forwards expire as follows:

July 31, 2023	$	180,892

	$	83,086,491

For U.S. federal income tax purposes, a change in ownership under IRC Section 382 may have occurred in a prior year. If an ownership change has occurred, the utilization of these losses against future income would be subject to an annual limitation. The annual limitation would be equal to the value of the Company immediately prior to the change in ownership multiplied by the IRC Section 382 rate in effect during the month of the change.

The Company’s Canadian net operating loss carry-forwards in Canadian dollars expire as follows:
