Shown because the letter names the company. A letter is commentary; it is not a record of why a position changed.

How to read this
A letter appears here only when its record names the company. The before figure is the manager’s 13F at the last quarter end on or before the letter’s date; the after figure is the next quarter end. A 13F shows the long US-listed equity book at a quarter end, filed up to 45 days later, and large books are listed to their largest positions. A company that is not among a manager’s listed positions may still be held below that range, through another security, or not at all: the filing cannot say which.
