A special feature of the form is that the SEC does not require a uniform "information table" for mutual funds to complete. Neither does it provide guidance on how to describe details of proposals. On the other hand, mutual funds rarely execute, manage, or report their votes themselves. Instead, they outsource those tasks to voting platforms. That implies, by linking the filing styles of mutual funds' N-PX forms with those of voting platforms, that I can identify each fund's use of different voting platforms. There are three dominant voting platforms currently on the market: ProxyExchange (owned by ISS), Viewpoint (owned by Glass Lewis), and ProxyEdge (owned by Broadridge). The following figure displays BlackRock and Putnam Investments' voting records (on their N-PX filings) in Apple Inc.'s 2019 annual meetings. We notice that both the table styles and proposal descriptions are different for the two N-PX forms.
