Most Freights Brokers prefer the BMC 84 bond over the BMC 85 trust fund option. This is simply because with the bond, you will not need to post collateral with the surety. The surety will complete their underwriting and will determine a premium. Once this premium is paid the bond is issued and remains in place for a 12 month period with automatic renewals each year. By using the bond, the Freight Broker chooses not to tie up his cash or credit. This improves your liquidity, and helps you operate a more financially sound business. A BMC-85 trust fund, on the other hand, is a form of security provided by you as the freight broker. You must pay a yearly fee, and place $75,000 cash in a trust account to cover future bond claims.
