Dear Shareholder,

In an effort to more closely align the existing investment philosophy, process, and objective with the Fund names, we have recently changed the names of two funds. The name of the WesMark Growth Fund is being changed to the WesMark Large Company Fund. In addition, the WesMark Small Company Growth Fund is being changed to the WesMark Small Company Fund. The changes better align the long-term investment management philosophy with Fund names.

The changes will be effective as of July 23, 2021. A copy of the July 23, 2021, amendment to the Prospectus dated February 28, 2021, which details the name changes and associated revisions, is set forth below for your reference.

Should you have any questions regarding these changes, please feel free to contact your WesMark Representative or Shareholder Services at 1-800-864-1013.

Equity securities may include common stocks, preferred stocks, securities (including debt securities) that are convertible into common stocks, and exchange traded funds (ETFs) and other investment companies. The Fund will invest primarily in securities issued by domestic companies.

The shares of ETFs are listed and traded on stock exchanges at market prices. The Fund may also purchase American Depository Receipts (ADRs) and other domestically traded securities of foreign companies.
