[1] During 2022, the Company sold shares of ACI and recognized a long-term capital gain for tax purposes of $251.5 million. The Company elected to retain the proceeds from this stock sale for general corporate purposes and pay corporate income tax on the taxable gain. The Company accrued and paid federal taxes of $47.3 million and estimated state and local taxes of $9.9 million on this undistributed long term capital gain. 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 for 2022. 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.
