The Company's authorized common stock consists of 350,000,000 shares at $ 0.01 par value per share. The Company had 174,115,111 and 172,656,458 shares of common stock issued and outstanding as of December 31, 2019 and 2018, respectively.

Partners in the Operating Partnership hold their ownership through common and special common units of limited partnership interest, hereinafter referred to as "common units." A common unit and a share of CBL's common stock have essentially the same economic characteristics, as they effectively participate equally in the net income and distributions of the Operating Partnership, except for certain special common units as disclosed in Note 10 . For each share of common stock issued by CBL, the Operating Partnership has issued a corresponding number of common units to CBL in exchange for the proceeds from the stock issuance. The Operating Partnership had 200,189,077 and 199,414,863 common units outstanding as of December 31, 2019 and 2018, respectively.

Each limited partner in the Operating Partnership has the right to exchange all or a portion of its common units for shares of CBL's common stock, or at the Company's election, their cash equivalent. When an exchange for common stock occurs, the Company assumes the limited partner's common units in the Operating Partnership. The number of shares of common stock received by a limited partner of the Operating Partnership upon exercise of its exchange rights will be equal, on a one-for-one basis, to the number of common units exchanged by the limited partner. If the Company elects to pay cash, the amount of cash paid by the Operating Partnership to redeem the limited partner's common units will be based on the five-day trailing average of the trading price, at the time of exchange, of the shares of common stock that would otherwise have been received by the limited partner in the exchange. However, for so long as the current distribution suspension results in the existence of a distribution shortfall (as described in the Partnership Agreement of the Operating Partnership) with respect to any of the S-SCUs, the L-SCUs or the K-SCUs (an “SCU Distribution Shortfall”), the Company may not elect to settle any exchange requested by a holder of common units of the Operating Partnership in cash, and may only settle any such exchange through the issuance of shares of common stock or other units of the Operating Partnership ranking junior to any such units as to which a distribution shortfall exists. The Company’s Board of Directors has prospectively approved that to the extent any partners exercise any or all of their exchange rights while the existence of the SCU Distribution Shortfall requires any exchange to be settled through the issuance of shares of common stock or other units of the Operating Partnership, the consideration paid shall be in the form of shares of common stock. Neither the common units nor the shares of CBL's common stock are subject to any right of mandatory redemption.

On March 1, 2013, the Company entered into the Sales Agreements (collectively, the "Sales Agreements") with a number of sales agents to sell shares of CBL's common stock, having an aggregate offering price of up to $ 300,000, from time to time in the ATM equity offerings (as defined in Rule 415 of the Securities Act of 1933, as amended) or in negotiated transaction (the "ATM program"). In accordance with the Sales Agreements, the Company will set the parameters for the sales of shares, including the number of shares to be issued, the time period during which sales are to be made and any minimum price below which sales may not be made. The Sales Agreements provide that the sales agents will be entitled to compensation for their services at a mutually agreed commission rate not to exceed 2.0% of the gross proceeds from the sales of shares sold through the ATM program. For each share of common stock issued by CBL, the Operating Partnership issues a corresponding number of common units of limited partnership interest to CBL in exchange for the contribution of the proceeds from the stock issuance. The Company includes only share issuances that have settled in the calculation of shares outstanding at the end of each period.

Since inception, the Company has sold $ 211,493 of common stock through the ATM program, at a weighted-average sales price of $ 25.12, generating net proceeds of $ 209,596, which were used to reduce the balances on the Company's credit facilities. Since the commencement of the ATM program, the Company has issued 8,419,298 shares of common stock and approximately $ 88,507 remains available that may be sold under this program as of December 31, 2019. The Company has not sold any shares under the ATM program since 2013. Actual future sales under this program, if any, will depend on a variety of factors including but not limited to market conditions, the trading price of CBL's common stock and the Company's capital needs. The Company has no obligation to sell the remaining shares available under the ATM program.

During 2019, the Operating Partnership elected to pay cash of $ 96 to a holder of 72,592 common units in the Operating Partnership upon the exercise of its conversion rights.

The Company's authorized preferred stock consists of 15,000,000 shares at $ 0.01 par value per share. A description of the Company's cumulative redeemable preferred stock is listed below. The Operating Partnership issues an equivalent number of preferred units to CBL in exchange for the contribution of the proceeds from CBL to the Operating Partnership when CBL issues preferred stock. The preferred units generally have the same terms and economic characteristics as the corresponding series of preferred stock.

The Company has 6,900,000 depositary shares, each representing 1/10th of a share of CBL's 6.625% Series E Preferred Stock with a par value of $ 0.01 per share, outstanding as of December 31, 2019 and 2018. The Series E Preferred Stock has a liquidation preference of $ 250.00 per share ($ 25.00 per depositary share). The dividends on the Series E Preferred Stock are cumulative, accrue from the date of issuance and are payable quarterly in arrears at a rate of $ 16.5625 per share ($ 1.65625 per depositary share) per annum. The Series E Preferred Stock generally has no stated maturity, is not subject to any sinking fund or mandatory redemption, and is not convertible into any other securities of the Company, except under certain circumstances in connection with a change of control. Owners of the depositary shares representing Series E Preferred Stock generally have no voting rights except under dividend default. The Company may redeem shares, in whole or in part, at any time for a cash redemption price of $ 250.00 per share ($25.00 per depositary share) plus accrued and unpaid dividends.

The Company has 18,150,000 depositary shares, each representing 1/10th of a share of CBL's 7.375% Series D Preferred Stock with a par value of $ 0.01 per share, outstanding as of December 31, 2019 and 2018. The Series D Preferred Stock has a liquidation preference of $ 250.00 per share ($ 25.00 per depositary share). The dividends on the Series D Preferred Stock are cumulative, accrue from the date of issuance and are payable quarterly in arrears at a rate of $ 18.4375 per share ($ 1.84375 per depositary share) per annum.

In December 2019, the Company announced the suspension of all future dividends on its 7.375% Series D Cumulative Redeemable Preferred Stock and 6.625% Series E Cumulative Redeemable Preferred Stock. Unpaid dividends on the Company’s preferred stock accrue without interest. The dividend suspension will be reviewed quarterly by the Board of Directors, but is expected to remain in place through at least year-end 2020. The Company will review taxable income on a regular basis and take measures, if necessary, to ensure that it meets the minimum distribution requirements to maintain its status as a REIT.

CBL paid a first quarter 2019 cash dividend on its common stock of $ 0.075 per share on April 16^th. Under the terms of a litigation settlement agreement, the Company did not pay any dividends to holders of its common shares payable in the third and fourth quarters of 2019 (see Note 15 for more information on the litigation settlement agreement). As noted above, in December 2019 the Company suspended all future dividends on its common stock and preferred stock, as well as distributions to all noncontrolling interest investors in its Operating Partnership (as noted below). No dividends may be paid on shares of the Company’s common stock unless (i) all accrued but unpaid dividends on its preferred stock, and any current dividend then due, have been paid in cash, or a cash sum sufficient for such payment has been set apart for payment and (ii) the SCU Distribution Shortfall created by its related suspension of distributions to noncontrolling interest investors in its Operating Partnership has likewise been remedied through the payment of distributions sufficient to satisfy such shortfall

for all prior periods and the then-current period (thereby allowing the resumption of distributions on the common units in the Operating Partnership that are held by the Company, which fund its common stock dividends) . The decision to declare and pay dividends on the Company’s common stock in the future, as well as the timing, amount and composition of any such future dividends, will be at the sole discretion of its b oard of d irectors. The total dividend included in accounts payable and accrued liabilities at December 31, 201 8 was $ 12,949 .
