MICROSOFT CORPORATION
One corporate group, resolved across 12 separately-registered clusters
in the same GLEIF corporate family (ultimate parent LEI INR2EJN1ERAN0W5ZP974). Each
member's own registration independently matches the family, so clusters that merely inherited a carrier's
LEI are excluded.
