[1] The value of the 2024 PSU awards is estimated on the date of grant using a Monte Carlo simulation model. The valuation consists of computing the fair value using CBL's simulated stock price as well as TSR over a three-year performance period. The award is modeled as a contingent claim in that the expected return on the underlying shares is risk-free and the rate of discounting the payoff of the award is also risk-free. The weighted-average fair value per share related to the 2024 PSUs consists of 50,825 PSUs at a fair value of $29.38 per share (which relates to the relative TSR) and 118,595 PSUs at a fair value of $22.12 per share (which relates to absolute TSR).

[2] PSUs granted shall be adjusted as if the shares of common stock represented by such PSUs had received any applicable stock or cash dividends declared. As for stock dividends, a number of PSUs shall be added to the target amount corresponding to the number of shares of common stock that would have been payable per such stock dividend on the then outstanding number of PSUs under the agreement as if common stock had been issued for such PSUs. As to cash dividends, a number of PSUs shall be added to the target amount corresponding to the number of shares of common stock that could have been acquired by the cash dividend payable on the then outstanding number of PSUs under the agreement as if common stock had been issued for such PSUs, and the calculation of the number of shares of common stock that could have been acquired shall be based on the closing price of the common stock on the record date for the cash dividend at issue.

[3] The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury securities in effect as of the valuation date, which is the grant date listed above.

[4] The computation of expected volatility for the 2024 PSUs was based on the historical volatility of CBL's shares of common stock for a trading period equal to the time from the grant date to the end of the performance period. Since the performance period exceeds CBL's trading history, volatility indications of comparable public companies were also considered.
