Retirement Benefits [Abstract]
DEFINED CONTRIBUTION PLANS	DEFINED CONTRIBUTION PLANSOur tax-deferred savings plan under our 401(k) Plan permits participating U.S. employees to contribute a portion of their pre-tax or after-tax earnings. In Canada, we have a Group Registered Retirement Savings Plan Program (the “RRSP”), which permits participants to make tax-deductible contributions. Our board of directors approved 50% matching contributions on employee contributions up to 4% of each employee’s eligible earnings. Our matching contributions to our 401(k) Plan and the RRSP for the three months ended September 30, 2020 and September 30, 2019 were $2.1 million and $1.8 million, respectively. Our matching contributions to our 401(k) Plan and the RRSP for the nine months ended September 30, 2020 and September 30, 2019 were $6.5 million and $5.2 million, respectively.
