[1] During 2023 and 2022, the Company sold shares of ACI common stock and recognized long-term capital gains for tax purposes of $241.2 million and $251.5 million, respectively. The Company elected to retain the proceeds from these stock sales for general corporate purposes and pay corporate income tax on the taxable gains. During 2023, the Company incurred federal taxes of $50.7 million and state and local taxes of $10.2 million. During 2022, the Company incurred federal taxes of $47.3 million and state and local taxes of $9.9 million. This undistributed long-term capital gain is allocated to, and reportable by, each shareholder, and each shareholder is also entitled to claim a federal income tax credit for its allocable share of the federal income tax paid by the Company. The allocable share of the long-term capital gain and the federal tax credit will be reported to direct holders of Kimco common stock, on Form 2439, and to others in year-end reporting documents issued by brokerage firms if the Company’s common stock is held in a brokerage account.
