| Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE DISCLOSURE As required by new pay versus performance (“PVP”) rules adopted by the SEC in 2022 and in effect for the first time for this proxy statement, the following Pay Versus Performance table (“PVP Table”) provides SEC-required during ● The information in columns (b) and (d) of the PVP Table comes directly from our Summary Compensation Tables, without adjustment; and ● As required by the SEC’s PVP rules, we describe the information in columns (c) and (e) of the PVP Table as “compensation actually paid” (or “CAP”) to the applicable NEOs. However, these CAP amounts may not necessarily reflect the final compensation that our NEOs actually earned or walked away with for their service in the Covered Years, respectively. As required by the SEC’s PVP rules, we provide information in the PVP Table below about our absolute total stockholder return (“TSR”) results, TSR results for a peer group of companies identified in the PVP Table, and our U.S. GAAP net income results during the Covered Years. We did not, however, actually base any compensation decisions for the PVP NEOs on, or link any PVP NEO pay to, the peer group TSR or our U.S. GAAP net income results because those are not metrics used in our short-term or long-term incentive plans during the Covered Years. In addition, the peer group used for purposes of this PVP Table disclosure is substantially different than the comparator companies against which we evaluate relative TSR performance for our named executive officers for purposes of our PSU awards, as described above in our Compensation Discussion and Analysis.
