ARTHUR J. GALLAGHER & CO.
One corporate group, resolved across 2 separately-registered clusters
in the same GLEIF corporate family (ultimate parent LEI 54930049QLLMPART6V29). Each
member's own registration independently matches the family, so clusters that merely inherited a carrier's
LEI are excluded.
