Equity - COPLP and Subsidiaries | Equity - COPT and Subsidiaries Preferred Shares As of December 31, 2017, COPT had 25.0 million preferred shares authorized and unissued at $0.01 par value per share. In 2017, COPT redeemed all of its outstanding preferred shares, including:
• | the 5.600% Series K Cumulative Redeemable Preferred Shares (the “Series K Preferred Shares”) redeemed effective January 21, 2017 at a price of $50.00 per share, or $26.6 million in the aggregate, plus accrued and unpaid dividends thereon through the date of redemption. Concurrently with this redemption, COPLP redeemed its Series K Preferred Units on the same terms. Since we made an irrevocable notification to holders of the Series K Preferred Shares in December 2016 of our intention to redeem such shares, we presented the liquidation preference of the shares as a liability on COPT’s consolidated balance sheet as of December 31, 2016; we also recognized a $17,000 decrease to net income available to common shareholders in 2016 pertaining to the original issuance costs incurred on the shares. The liability associated with these shares as of December 31, 2016 is classified in Level 2 of the fair value hierarchy; and
• | the 7.375% Series L Cumulative Preferred Shares (the “Series L Preferred Shares”) redeemed effective June 27, 2017 at a price of $25.00 per share, or $172.5 million in the aggregate, plus accrued and unpaid dividends thereon up to but not including the date of redemption. Concurrently with this redemption, COPLP redeemed its Series L Preferred Units on the same terms. We also recognized a $6.8 million decrease to net income available to common shareholders in 2017 pertaining to the original issuance costs incurred on the shares.
Common Shares In October 2012, COPT established an at-the-market (“ATM”) stock offering program under which it could, from time to time, offer and sell common shares in “at the market” stock offerings having an aggregate gross sales price of up to $150.0 million. COPT issued 890,241 common shares under this program in 2015 at a weighted average price of $30.29 per share. Net proceeds from the shares issued totaled $26.6 million, after payment of $0.4 million in commissions to sales agents; COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. As discussed below, this program was replaced by a new ATM program established in 2016. In September 2016, COPT established a new ATM stock offering program under which it may, from time to time, offer and sell common shares in “at the market” stock offerings having an aggregate gross sales price of up to $200.0 million. This program replaced the ATM stock offering program that we previously had in place. COPT issued the following common shares under this ATM program:
• | 3.72 million common shares in the three months ended December 31, 2016 at a weighted average price of $29.56 per share. Net proceeds from the shares issued totaled $109.1 million, after payment of $0.9 million in commissions to sales agents; and
• | 591,000 common shares in 2017 at a weighted average price of $33.84 per share. Net proceeds from the shares issued totaled $19.7 million, after payment of $0.3 million in commissions to sales agents.
COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. COPT’s remaining capacity under this ATM program as of December 31, 2017 was an aggregate gross sales price of $70.0 million in common share sales. On November 2, 2017, COPT entered into forward equity sale agreements to issue 9.2 million common shares at an initial gross offering price of $285.2 million, or $31.00 per share, before underwriting discounts, commissions and offering expenses. The forward sale price that we expect to receive upon physical settlement of the agreements will be subject to adjustment on a daily basis based on a floating interest rate factor equal to the overnight bank funding rate less a spread, and will be decreased on each of certain dates specified in the agreements during the term of the agreements. On December 27, 2017, COPT issued 1.7 million common shares under the agreements for net proceeds of $50.0 million. COPT contributed the net proceeds from these issuances to COPLP in exchange for an equal number of units in COPLP. Holders of COPLP common units converted their units into COPT common shares on the basis of one common share for each common unit in the amount of 339,513 in 2017, 87,000 in 2016 and 160,160 in 2015. COPT declared dividends per common share of $1.10 in 2017, 2016 and 2015. See Note 15 for disclosure of common share activity pertaining to our share-based compensation plans.

Equity - COPLP and Subsidiaries | Equity - COPLP and Subsidiaries General Partner Preferred Units In 2017, COPLP redeemed all of the outstanding units of the following series of preferred units held by COPT:
• | the 5.600% Series K Preferred Shares effective on January 21, 2017. Since notification of this redemption occurred in December 2016, we present the liquidation preference of the related units as a liability on COPLP’s consolidated balance sheet as of December 31, 2016; we also recognized at a price of $50.00 per unit, or $26.6 million in the aggregate, plus accrued and unpaid distributions thereon through the date of redemption, and recognized a $17,000 decrease to net income available to common unitholders pertaining to the units’ original issuance costs at the time of redemption; and
• | the 7.375% Series L Cumulative Preferred Units on June 27, 2017 at a price of $25.00 per unit, or $172.5 million in the aggregate, plus accrued and unpaid distributions thereon through the date of redemption, and recognized a $6.8 million decrease to net income available to common unitholders pertaining to the units’ original issuance costs at the time of redemption.
With the completion of these redemptions in 2017, no preferred units in COPLP are held by COPT. Limited Partner Preferred Units COPLP has 352,000 Series I Preferred Units issued to an unrelated party that have an aggregate liquidation preference of $8.8 million ($25.00 per unit), plus any accrued and unpaid distributions of return thereon (as described below), and may be redeemed for cash by COPLP at COPLP’s option any time after September 22, 2019. The owner of these units is entitled to a priority annual cumulative return equal to 7.5% of their liquidation preference through September 22, 2019; the annual cumulative preferred return increases for each subsequent five-year period, subject to certain maximum limits. These units are convertible into common units on the basis of 0.5 common units for each Series I Preferred Unit; the resulting common units would then be exchangeable for COPT common shares in accordance with the terms of COPLP’s agreement of limited partnership. Common Units COPT owned 96.9% of COPLP’s common units as of December 31, 2017 and 96.5% as of December 31, 2016. From 2015 through 2017, COPT acquired additional common units through the following common share issuances under ATM programs:
• | 591,042 common shares in 2017 at a weighted average price of $33.84 per share. Net proceeds from the shares issued totaled $19.7 million, after payment of $0.3 million in commissions to sales agents;
• | 3.72 million common shares issued in 2016 at a weighted average price of $29.56 per share. Net proceeds from the shares issued totaled $109.1 million, after payment of $0.9 million in commissions to sales agents; and
• | 890,241 common shares issued in 2015 at a weighted average price of $30.29 per share. Net proceeds from the shares issued totaled $26.6 million, after payment of $0.4 million in commissions to sales agents.
In December 2017, COPT also acquired additional common units from COPT’s issuance of 1.7 million common shares under its forward equity sale agreements for net proceeds of $50.0 million. Limited partners in COPLP holding common units have the right to require COPLP to redeem all or a portion of their common units. COPLP (or COPT as the general partner) has the right, in its sole discretion, to deliver to such redeeming limited partners for each partnership unit either one COPT common share (subject to anti-dilution adjustment) or a cash payment equal to the then fair market value of such share (so adjusted) (based on the formula for determining such value set forth in the partnership agreement). Limited partners holding common units redeemed their units into common shares on the basis of one common share for each common unit in the amount of 339,513 in 2017, 87,000 in 2016 and 160,160 in 2015. We declared distributions per common unit of $1.10 in 2017, 2016 and 2015.
