His 2021 season salary is payable in a lump sum in November 2021. (Presumably this is after the season is over.) This creates a short-term deferral arrangement (not 409A deferred compensation), because it is paid no later than November of the year it is earned and vested However, Bauer can opt out of the contract after the season ends (anytime until the November payment date??), and if he does, $20M of his salary is deferred and paid in $2M installments over the period 2031-2040. This creates 409A deferred compensation. You cannot have an elective deferral of a short-term deferral arrangement unless you comply with the one year/five year rule. Here Bauer is not required to make the election more than 1 year before the salary is otherwise payable. (The 5-year rule is met, because he defers the initial installment for at least 5 years, until 2031.) I expect there may be more to this contract than we know, I'm pretty sure his tax advisors would not design a non-compliant deferred compensation arrangement!
If anyone finds out more about it, please post!
