Business owners with multiple owners should establish a buy-sell agreement to determine how ownership shares will be bought out upon certain triggering events such as retirement, death, disability, or termination of employment. The agreement must define the triggering events, determine the value of the company using either a fixed price, formula, or appraisal method, and establish how the buyout will be funded through cash, shareholder loans, or life insurance. Properly establishing these key elements in advance can minimize stress when a buyout occurs.
