776.1.12. If, at any time, control of a corporation is acquired by a person or group of persons, no amount may be deducted by the corporation under section 776.1.9 for a taxation year ending after that time in respect of the unused portion of the tax credit of the corporation for a taxation year ending before that time.
However, the corporation may deduct an amount under section 776.1.9 for a particular taxation year ending after the time referred to in the first paragraph, in respect of the portion that may reasonably be considered to be attributable to the carrying on of a business, of the unused portion of the tax credit of the corporation for a taxation year ending before that time, if the corporation carried on the business throughout the particular taxation year for profit or with a reasonable expectation of profit.
The amount that the corporation may deduct under section 776.1.9 for the particular taxation year in respect of the portion described in the second paragraph is to be determined as if the reference in the first paragraph of that section to the tax payable under this Part for a taxation year, determined before the application of this Title, were a reference to the portion of the tax payable under this Part by the corporation for the particular taxation year, determined before the application of this Title, that may reasonably be attributed to the carrying on of the business referred to in the second paragraph and, if the corporation sold, leased, rented or developed properties or rendered services in the course of carrying on that business before the time referred to in the first paragraph, of any other business substantially all the income of which is derived from the sale, leasing, rental or development, as the case may be, of similar properties, or the rendering of similar services.
