After Altera’s victory in Tax Court in 2015, many companies with cost sharing arrangements (“CSA”) ceased sharing stock-based compensation (“SBC”) costs. To address the possibility of a reversal on appeal, many of these companies added reverse claw-back provisions to their CSAs. Under these provisions, in the year a reversal of Altera becomes final, the US participant typically “claws back” from the foreign participants the amount of SBC costs not shared in prior years (the “claw-back true-up”). The effect is a large inclusion of SBC costs into the US participant’s income in the year the reversal becomes final.
These reverse claw-back provisions were revisited by companies in 2019, when the Ninth Circuit reversed the Tax Court, and in 2020, when the U.S. Supreme Court declined to hear Altera’s appeal. Companies were concerned about whether the IRS would respect the provisions or insist that adjustments be made year-by-year. Should taxpayers report the claw-back amount in 2020, or amend prior year returns to include the SBC costs in the cost pool for each open year, or modify the CSA to defer or cancel the payment pending IRS guidance? On July 13, 2021, the IRS provided guidance on these questions, in the form of a Chief Counsel Memorandum, AM-2021-004 (the “CCM”).
