On the occasion when a person becomes absolutely entitled to any settled property as against the trustee all the assets forming part of the settled property to which he becomes so entitled shall be deemed to have been disposed of by the trustee, and immediately reacquired by him in his capacity as a trustee within section 60(1), for a consideration equal to their market value.

On the occasion when a person becomes absolutely entitled to any settled property as against the trustee, any allowable loss which has accrued to the trustee in respect of property which is, or is represented by, the property to which that person so becomes entitled (including any allowable loss carried forward to the year of assessment in which that occasion falls), being a loss which cannot be deducted from chargeable gains accruing to the trustee in that year, but before that occasion, shall be treated as if it were an allowable loss accruing at that time to the person becoming so entitled, instead of to the trustee.

References in this section to the case where a person becomes absolutely entitled to settled property as against the trustee shall be taken to include references to the case where a person would become so entitled but for being an infant or other person under disability.
