77.1. If, in a taxation year, an employee is deemed by reason of section 53 to have disposed of a security, as defined in section 47.18, held by a trust, the trust disposed of the security to the person that issued the security, the disposition occurred as a result of the employee not meeting the conditions necessary for title to the security to vest in the employee, and the amount paid by the person to acquire the security from the trust or to redeem or cancel the security did not exceed the amount paid to the person for the security, the following rules apply:(a) there may be deducted in computing the employee’s income for the year from an office or employment the amount by which the amount of the benefit deemed by section 49 to have been received by the employee in the year or a preceding taxation year in respect of the security exceeds any amount deducted under section 725.2 or 725.3 in computing the employee’s taxable income for the year or a preceding taxation year in respect of that benefit; and
(b) notwithstanding any other provision of this Part, any gain or loss of the employee otherwise determined from the disposition of the security is deemed to be nil, and Division I of Chapter III of Title IX of Book III does not apply to deem a dividend to have been received in respect of the disposition.
