About this market data

IEX historical data reflects IEX activity only and is presented as a source-scoped reference point, not as consolidated U.S. market history.

Screened reference metrics use K9-qualified IEX reference history and only explicitly registered positive split events. They do not assert complete split history, consolidated U.S. market performance, or canonical adjusted prices.

Data provided for free by IEX. By accessing or using IEX Historical Data, you agree to the IEX Historical Data Terms of Use.

The raw chart can show a discontinuity around a stock split because it is intentionally unadjusted. The screened metrics use only explicitly registered positive split events and do not assert complete split history.

Company Research Map

These reviewed encyclopedia concepts are supported by public-company evidence for this business. Operating-model groups show how the reported concepts fit together without implying that every metric in the broader model is reported by this issuer.

Research coverage

Start with an operating model, then move into the supported concepts and economic bridges below. Coverage counts describe reviewed evidence links for this issuer, not standardized KPI completeness.

Payroll & HCM Economics

15 reviewed concepts

Connect recurring Employer Services economics, PEO worksite and benefits-pass-through economics, and client-funds float earnings to understand payroll and HCM business economics.

How these metrics connect

These bridges come from the reviewed operating model. Linked concepts have public-company evidence for this issuer; broader bridge coverage remains explicit when the model contains additional concepts.

Employer Services growth and retention
6 of 6 reviewed concepts

Employer Services revenue combines recurring payroll and HCM relationships with new business starts, client revenue retention, pricing, pays per control, and other drivers. New business bookings are an earlier sales measure, while organic constant-currency growth and segment margin show later revenue and profitability outcomes.

Client-funds balance, yield, and earnings
4 of 4 reviewed concepts

Average client funds balances multiplied by portfolio yield provide the core economic bridge into interest revenue, while the extended investment strategy net impact includes additional investment and financing effects. Client funds remain restricted by corresponding client obligations rather than functioning as unrestricted corporate cash.
