Severance

Severance

Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workload demands due to the loss of customers purchasing certain services.

Changes in our accrued liabilities for severance expenses were as follows:

	Severance

Balance at December 31, 2020	$	103
Accrued to expense	—
Payments, net	(51)
Balance at June 30, 2021	$	52
