What is my tax responsibility as a 2nd-generation beneficiary on the capital gains of a GST-exempt trust?

Question

While alive, my grandfather created two trusts - one in his name and one in his spouse's name. After both grandparents had died, to my understanding their two children received the income of the trust, but could not liquidate the assets. When my aunt recently died the stocks in the trusts "For the benefit" of her were transferred to an account in my name and subsequently liquidated per my request. All of these stocks were acquired after both grandparents had died. What is my responibility, if any, for the capital gains of these stocks?

Thank you!

Complicated question. You need to contact the trustee  and request a statement of the book value of the stocks as distributed to you. This will allow you to compute any gain realized when you sold the stocks in your name.
