Definitions

In plain terms

If only 60% of a company's shares are treated as freely available, the float-adjusted capitalization uses that fraction rather than all shares.

Technical

The measure multiplies eligible price, shares, and free-float or investability factor, with explicit rounding, bands, foreign limits, effective dates, and methodology version.

Scope

Free float is provider- and methodology-defined and is not simply shares not held by insiders in every market.
