12.  Company-wide Realignments

On May 28, 2020, the Board of Directors of the Company approved a restructuring plan (the “2020 Realignment”) to align its organization with the Company’s sole focus on the commercialization of its products. The 2020 Realignment reduced the Company’s headcount. For the year ended December 31, 2020, total expense was comprised of $4.1 million for one-time termination benefits to the affected employees, including severance and health care benefits, offset by a $0.4 million reversal of non-cash, share-based compensation expense related to forfeited, unvested equity awards. As of September 30, 2021, the Company had made substantially all of the payments related to the 2020 Realignment.

In July 2020, following the acquisition of Tetraphase, the Company incurred one-time charges related to a reduction in the combined Company’s headcount. For the year ended December 31, 2020, total expense was comprised of $3.1 million for one-time termination benefits to the affected employees, including severance and health care benefits. As of September 30, 2021, the Company had made substantially all of the payments related to this reduction in headcount.
