| Pay vs Performance [Table Text Block] | Pay Versus Performance Table Pursuant to Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the Pay Versus Performance Table (set forth below) is required to include “compensation actually paid,” as calculated per SEC disclosure rules, to the Company’s principal executive officer (“PEO”) and the Company’s non-PEO named executive officers (“NEOs”), as noted below. “Compensation actually paid” represents a new required calculation of compensation that differs significantly from the Summary Compensation Table calculation of compensation, the NEO’s realized or earned compensation, as well as from the way in which the Compensation Committee views annual compensation decisions, as discussed in the Executive Compensation Discussion and Analysis. The amounts in the table below are calculated in accordance with SEC rules and do not represent amounts actually earned or realized by NEOs.

The yearly percentage change in cumulative total shareholder return was measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for the period from December 31, 2019 through and including the last day of the covered fiscal year (the “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between stock price per share at the end and the beginning of the Measurement Period, divided by (b) stock price per share at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of the Measurement Period to produce the year-end values of such investment as of the end of 2022, 2021 and 2020 as applicable. For purposes of this pay versus performance disclosure, our peer group NASDAQ U.S. Benchmark TR Index (U.S. companies) (the “Peer Group”). Because fiscal years are presented in the table in reverse chronical order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.
