The Foundation would not have been subject to an underdistribution penalty under 4942 for the year 2024 if the average value of the assets had been properly recorded in Part IX. Therefore, the Foundation has chosen not to amend Form 990-PF for taxable year ending December 31, 2024. Instead, the Foundation has adjusted the amount reported in Part XII of Form 990-PF for year ending December 31,2025 to reflect the correct balance.
