Related party transaction, terms and manner of settlement		On March 18, 2021, the Company and Carolyn Anderson Short, its co-founder and Chief of Intellectual Property & Strategy, mutually agreed that Ms. Short would depart the Company on May 31, 2021 following an agreed upon transition period. The Transition Agreement provides for the following severance benefits in exchange for a release of claims by Ms. Short: (i) a lump sum payment equal to eighteen (18) months of Ms. Short’s current base salary, (ii) a payment at her targeted bonus rate for 2021, pro-rated to the separation date, and (iii) accelerated full vesting of her equity awards including 7,747 stock options and 138,461 restricted stock units. The modification of these equity awards resulted in an incremental fair value of $7.0 million which will be recognized on a straight-line basis over the transition service period. For the three months ended March 31, 2021, the Company recognized $0.2 million related to the lump sum salary payment and target bonus, and a $1.0 million non-cash charge related to the modified equity awards.
