[1] | Non-cash benefits/(charges) include non-cash write-offs and accelerated depreciation of right-of-use ("ROU") assets and leasehold improvements and a non-cash benefit for adjustments to stock compensation for awards forfeited by employees. These amounts have been removed from the liability balance in the table above as they do not impact the restructuring accruals.
[2] | As described in Note 4, on August 1, 2019, the Company’s Board of Directors approved an overall plan to change the Company’s operating model and improve its business processes and cost structure by reducing its headcount and consolidating various facilities. For the year ended December 31, 2020, the Company incurred $36.8 million of expenses related to this plan. While certain of these expenses may be identifiable to the Company’s segments, primarily the Company’s Consumer-to-Consumer segment, the expenses are not included in the measurement of segment operating income provided to the CODM for purposes of assessing segment performance and decision making with respect to resource allocation.
