Marsh & Mclennan Companies, Inc.
A giant in insurance broking and consulting, Marsh McLennan helps companies manage risk through its Marsh, Guy Carpenter, Mercer, and Oliver Wyman brands, serving clients across dozens of countries. It began when rival brokers Henry Marsh and Donald McLennan were told by a railroad's directors to work together, merging their firms in 1905. Founder Henry Marsh once defended chasing big corporate clients by asking, "What's the use of shooting hummingbirds when elephants are so much easier to hit?"

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -407.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
