The supreme body of the Bayer Pensionskasse Schweiz is its Board of Trustees. Responsibility for implementing the resolutions of the Board of Trustees lies with the Managing Director.

The Board of Trustees is responsible for ensuring that due and full regard is consistently paid to the law and the fund's regulations. The Board of Trustees' further key duties include defining the fund's benefits and the financing thereof, determining overall asset investment strategy, approving the annual financial statements and determining the annual interest to be paid on working insurees' savings amounts.  The Board of Trustees consists of an equal number of employer's and employees' representatives (four of each) from the three affiliated Bayer companies.

In addition to implementing the resolutions of the Board of Trustees, the fund's Managing Director is responsible for applying the fund regulations, observing all relevant legal provisions, conducting the fund's operational management and (particularly) maintaining contact with the fund's insurees.
