My Grandmother Passed Away And I Received A Piece Of Mail From Her Former Employer.

As the title states, my grandmother passed away but during the 2 years I took care of her she never mentioned anything about life insurance, I received a piece of mail from her former employer but I don't know what it means. Could someone knowledgeable please interpret what this means for me please? It reads as follows:

"This is a summary of the annual report of AmPlan, The Amtrak Union Benefits Plan For Retired Employees.(Followed by her EIN and plan number) for the plan year 01/01/2023- 12/31/2023.
