Key Terms

4 terms

ten percent owner regulatory

"Reporting person David E. Rainbolt is listed as a ten percent owner"

indirect ownership financial

"Shares were reported as indirect ownership through the David and Kim Rainbolt Foundation"

revocable trust financial

"Held under: Dana Kim Rainbolt Revocable Trust for the reporting person's spouse"

A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.

general partner financial

"Shares held at BF Bank Partners, LP where David E. Rainbolt is General Partner"

A general partner is the person or firm that runs an investment partnership and legally represents it — they make the day-to-day decisions, choose which assets to buy or sell, and are responsible for the partnership’s obligations. Investors care because the general partner’s judgment, risk-taking and fee and profit-sharing arrangements determine both the potential returns and the level of exposure to losses; think of the GP as the ship’s captain whose skill and honesty shape the voyage’s outcome.
