| IRS990ScheduleA/Form990ScheduleAPartVIGrp/ExplanationTxt | 0 | THERE WAS A CONTRACT BETWEEN MR. MULLIN AND THE FOUNDATION GOVERNING THE OWNERSHIP, USE, MAINTENANCE, AND STORAGE OF JOINTLY HELD AUTOMOBILES. THE FOUNDATION AND ONE OF ITS DECEASED DIRECTORS HAD AN INTEREST IN ATLANTIC, LLC. TOGETHER, THEY OWNED A MINORITY INTEREST. AN INDEPENDENT THIRD PARTY OWNS THE REMAINING MAJORITY INTEREST. THE PURPOSE OF ATLANTIC WAS TO ACQUIRE, MANAGE, OPERATE AND DISPLAY A 1935 BUGATTI T-57SC AUTOMOBILE. THE PAST DIRECTOR, A DISQUALIFIED PERSON UNDER SECTION 4946, DOES NOT MAINTAIN IMPERMISSIBLE CONTROL OF THE FOUNDATION IN CONNECTION WITH THEIR RESPECTIVE INTERESTS IN ATLANTIC, LLC FOLLOWING MR. MULLIN'S PASSING IN SEPTEMBER 2023, THE FOUNDATION INITIATED THE PROCESS OF WINDING DOWN ITS AFFAIRS. DURING 2024, THE FOUNDATION SOLD ITS OWNERSHIP INTEREST IN ATLANTIC TO THE MAJORITY OWNER OF THE ENTITY FOR TOTAL PROCEEDS OF $4,734,450. AS A RESULT OF THE SALE, THE FOUNDATION RECOGNIZED A NET GAIN OF $2,243,233, WHICH IS INCLUDED IN THE ACCOMPANYING STATEMENTS OF ACTIVITIES.
