What are the U.S. federal income tax consequences of the liquidating distributions to U.S. stockholders?

“In general, distributions made pursuant to the Plan of Complete Liquidation and Dissolution, including the pre-dissolution liquidating distribution, will be treated for U.S. federal income tax purposes as a series of distributions in complete liquidation of Altaba in which amounts received by stockholders are treated as full payment in exchange for their shares of Altaba common stock.”
