Segment Reporting [Abstract]
Franchise Fees	Domestic franchisee agreements generally require the franchisee to pay the Company an initial franchise fee for the franchisee's principal office plus a royalty fee that is a percentage of gross commission income, if any, earned by the franchisee. Franchisee fees can be structured in numerous ways. The Company utilizes multiple franchise fee models, including: (i) volume-based incentive (under which royalty fee rate is subject to reduction based on volume incentives); (ii) flat percentage royalty fee (under which the franchisee pays a fixed percentage of their commission income); (iii) capped fee (under which the franchisee pays a royalty fee capped at a set amount per independent sales agents per year); and (iv) tiered royalty fee (under which the franchisee pays a percentage of their gross commission income as a royalty fee). The volume incentives currently in effect vary for each eligible franchisee for which the Company provides a detailed table that describes the gross revenue thresholds required to achieve a volume incentive and the corresponding incentive amounts and are subject to change.
