Subsequent Events [Abstract]
Subsequent events	Subsequent events On August 1, 2018, Planet Fitness Master Issuer, LLC (the “Master Issuer”), a limited-purpose, bankruptcy remote, wholly-owned indirect subsidiary of Pla-Fit Holdings, LLC, entered into a base indenture and a related supplemental indenture (collectively, the “Indenture”) under which the Master Issuer may issue multiple series of notes. On the same date, the Master Issuer issued Series 2018-1 4.262% Fixed Rate Senior Secured Notes, Class A-2-I (the “Class A-2-I Notes”) with an initial principal amount of $575,000 and Series 2018-1 4.666% Fixed Rate Senior Secured Notes, Class A-2-II (the “Class A-2-II Notes” and, together with the Class A-2-I Notes, the “Class A-2 Notes”) with an initial principal amount of $625,000. In connection with the issuance of the Class A-2 Notes, the Master Issuer also entered into a revolving financing facility that allows for the issuance of up to $75,000 in Series 2018-1 Variable Funding Senior Notes, Class A-1 (the “Variable Funding Notes”), and certain letters of credit, all of which is currently undrawn. The Notes were issued in a securitization transaction pursuant to which most of the Company’s domestic revenue-generating assets, consisting principally of franchise-related agreements, certain corporate-owned store assets, equipment supply agreements and intellectual property and license agreements for the use of intellectual property, are held by the Master Issuer and certain other limited-purpose, bankruptcy remote, wholly-owned indirect subsidiaries of the Company that act as guarantors of the Notes and that have pledged substantially all of their assets to secure the Notes. The legal final maturity date of the Class A-2 Notes is in August 2048, but it is anticipated that, unless earlier prepaid to the extent permitted under the Indenture, the Class A-2-I Notes will be repaid in August 2022 and the Class A-2-II Notes will be repaid in August 2025. A portion of the proceeds of the Notes was used to repay the remaining $705,877 of principal outstanding on the existing senior secured credit facility. The additional proceeds, net of transaction costs, are being used for general corporate purposes, and may include a return of capital to the Company’s shareholders. On August 9, 2018, the Company announced that its Board of Directors approved an increase to the total amount of the share repurchase program to $500,000. The timing of the purchases and the amount of stock repurchased is subject to the Company’s discretion and will depend on market and business conditions, the Company’s general working capital needs, stock price, applicable legal requirements and other factors. Our ability to repurchase shares at any particular time is also subject to the terms of the indenture governing our outstanding notes. Purchases may be effected through one or more open market transactions, privately negotiated transactions, transactions structured through investment banking institutions, or a combination of the foregoing. Planet Fitness is not obligated under the program to acquire any particular amount of stock and can suspend or terminate the program at any time.
