Shareholders' Equity

Shareholders' Equity of the General Partner and Partners' Capital of the Partnership

General Partner

The General Partner has an at the market ("ATM") equity program that allows it to issue and sell its common shares through sales agents from time to time. Actual sales under the ATM equity program depend on a variety of factors to be determined by the General Partner, including, among others, market conditions, the trading price of the General Partner’s common stock, determinations by the General Partner of the appropriate sources of funding and potential uses of funding available.

In February 2021, the General Partner terminated its previous equity distribution agreement for the ATM equity program and entered into a new equity distribution agreement pursuant to which the General Partner may sell from time to time up to an aggregate offering price of $400.0 million of its common stock through sales agents or forward sellers. No forward sales were executed in 2021 and substantially all of the capacity of this ATM program was utilized as of December 31, 2021.

During 2021, the General Partner issued 8.2 million common shares pursuant to its ATM equity programs, generating gross proceeds of $408.3 million and, after deducting commissions and other costs, net proceeds of $403.6 million. The proceeds from these offerings were contributed to the Partnership and used to fund development activities.

During 2020, the General Partner issued 4.6 million common shares pursuant to its ATM equity programs, generating gross proceeds of $177.1 million and, after deducting commissions and other costs, net proceeds of $175.0 million. The proceeds from these offerings were contributed to the Partnership and used to fund development activities.

During 2019, the General Partner issued 8.0 million common shares pursuant to its ATM equity program, generating gross proceeds of approximately $266.3 million and, after deducting commissions and other costs, net proceeds of approximately $263.3 million. The proceeds from these offerings were contributed to the Partnership and used to fund development activities.

Partnership

For each common share or preferred share that the General Partner issues, the Partnership issues a corresponding General Partner Unit or Preferred Unit, as applicable, to the General Partner in exchange for the contribution of the proceeds from the stock issuance. Similarly, when the General Partner redeems or repurchases common shares or preferred shares, the Partnership redeems the corresponding General Partner Units or Preferred Units held by the General Partner at the same price.
