Retirement Benefits [Abstract]
Employee Benefit Plan	Employee Benefit Plan We offer the GP Retirement Savings Plan (the “Plan”) to our employees in the United States. Eligible employees are automatically enrolled unless they elect to not participate in the Plan, and contributions begin as soon as administratively feasible after enrollment. The Plan permits pre-tax contributions to the Plan by participants pursuant to Section 401(k) of the Internal Revenue Code (IRC). We make matching contributions at our discretion. In 2019, 2018 and 2017, we contributed 219,427, 162,572, and 104,751 shares, respectively, of our common stock directly to the Plan which had a value of approximately $3.0 million, $3.0 million and $2.7 million, respectively, and is recognized as compensation expense in the consolidated statements of operations for matching contributions to the Plan. We also maintain several defined contribution pension plans for our employees in the United States, United Kingdom and other countries. We contributed to these plans $2.7 million, $2.7 million and $2.5 million during the years ended December 31, 2019, 2018 and 2017, respectively.
