Methodology & FAQ
How This Position History Is Sourced
Each row is one SEC Form 13F-HR filing disclosing this position. Share count, market value, and reported quarter are taken verbatim from the filing; portfolio weight is recomputed against the same filing's total reported equity book. Implied price-per-share is market value divided by shares — a quarter-end mark, not the manager's cost basis. See the full methodology document for the normalization rules.
When did GATES FOUNDATION TRUST first disclose a WM position in 13F-HR filings?
GATES FOUNDATION TRUST first reported WASTE MANAGEMENT INC (WM) on its 13F-HR filing for the period ending 2016-03-31 (Q1 2016). The position has appeared on 41 reported quarters within Pactolio's tracked window.
What was GATES FOUNDATION TRUST's most recent quarter-over-quarter share-count change in WM?

Does the implied price-per-share represent GATES FOUNDATION TRUST's cost basis in WM?
No. The implied price-per-share column is the 13F-HR reported market value divided by reported share count on the filing date (end of quarter). It is a quarter-end mark, not a cost basis or transaction price. Use it as a sanity check on the value column, not as an indicator of the manager's entry or exit price.
