Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered funds disclose how they voted every proxy and institutional managers disclose their votes on executive pay (say-on-pay, say-on-frequency and golden parachutes), and Form 8-K Item 5.07, in which the company reports its own meeting results.

At MKS INSTRUMENTS INC.'s shareholder meeting held May 7, 2024, in the 2023-2024 proxy season, 383 asset managers reported how they voted on 6 ballot items in their SEC Form N-PX filings, covering 3,343 separate fund positions. On the most widely held item on that ballot — The approval, on an advisory basis, of executive compensation. — FOR was 93% of the votes cast (FOR divided by FOR plus AGAINST, the conventional basis for proxy support; abstentions, broker non-votes and unvoted shares are excluded because none of them took a side), which is more than half. Whether the item was approved is for the filing to say; that statement has not been read for this item.
