There are three main types of purchase and sale contracts: (1) the “buy-back agreement, under which the company acquires the shares of the outgoing owner”, (2) the “cross-purchase” contract, under which the remaining owners buy the outgoing owner, and (3) the “hybrid” agreement, under which the company and the owner may have an option to buy back the outgoing owner. The purchase-sale agreement can take the form of a cross-purchase plan or a pension plan (entity or share buyback). For more neutrality and efficiency of the purchase-sale agreement, the service of a corporate trustee is recommended. The most overlooked event that a buy/sell should also address is a handicap. For example, transfers to revocable trusts are very often permitted, as are transfers to direct family members. One thing to keep in mind when dealing with all forms of business is that you can often change the legal provisions that govern the duties and rights of owners by agreement. If a buyout is triggered by a death, it is usually funded by life insurance. When concluding a purchase/sale contract, each partner took out a life insurance policy equal to the value of his or her ownership shares. The most common mistake is that partners try to save money by subtracting term life insurance, and the insurance expires before a triggering event, creating a similar event, if not worse, than if they didn`t have a deal. I highly recommend using permanent life insurance to avoid this problem. .
