Based upon similar operational and economic characteristics, the Company’s revenues are disaggregated by its three strategic pillars: Human Capital Management (“HCM”), HR Outsourcing (“HRO”), and Global (“Global”) Solutions, with separate disaggregation for PEO zero-margin benefits pass-through revenues and client fund interest revenues. The Company believes these revenue categories depict how the nature, amount, timing, and uncertainty of its revenue and cash flows are affected by economic factors.

HCM provides a suite of product offerings that assist employers of all types and sizes in all stages of the employment cycle, from recruitment to retirement. Global is generally consistent with the types of services provided within HCM but represent geographies outside of the United States and includes our multinational offerings. HCM and Global revenues are primarily attributable to fees for providing solutions for payroll, benefits, talent, retirement services and HR processing and fees charged to implement the Company's solutions for clients.

HRO provides a comprehensive human resources outsourcing solution, including offering benefits, providing workers’ compensation insurance, and administering state unemployment insurance, among other human resources functions. This revenue is primarily driven by PEO. The Company has further disaggregated HRO to separate out its PEO zero-margin benefits pass-through revenues.

The Company recognizes client fund interest revenues on collected but not yet remitted funds held for clients in revenues as earned, as the collection, holding and remittance of these funds are critical components of providing these services.

The following tables provide details of revenue by our strategic pillars with disaggregation for PEO zero-margin benefits pass-throughs and client fund interest, and includes a reconciliation to the Company’s reportable segments:

The timing of revenue recognition for our HCM, HRO and Global Solutions is consistent with the invoicing of clients, as invoicing occurs in the period the services are provided. Therefore, the Company does not recognize a contract asset or liability resulting from the timing of revenue recognition and invoicing.
