Equity [Abstract]  
On April 22, 2013, COPT redeemed all of its outstanding 7.625% Series J Preferred Shares of beneficial interest (the “Series J Preferred Shares”) at a price of $25 per share, or $84.8 million in the aggregate, plus accrued and unpaid dividends thereon through the date of redemption. Concurrently, COPLP redeemed the Series J Preferred Units previously owned by COPT that carried terms substantially the same as the Series J Preferred Shares. At the time of the redemption, we recognized a $2.9 million decrease to net income available to common shareholders/unitholders pertaining to the original issuance costs incurred on these securities.

On March 19, 2013, COPT completed a public offering of 4,485,000 common shares at a price of $26.34 per share for net proceeds of $118.1 million (after underwriter discounts but before offering expenses) that were contributed to COPLP in exchange for 4,485,000 common units.

On July 15, 2013, COPT issued 1.5 million common shares at a weighted average price of $26.05 per share under its at-the-market (“ATM”) stock offering program established in October 2012, representing its first issuance under the ATM program. Net proceeds from the shares issued totaled $38.5 million, after payment of $586,000 in commissions to sales agents. The proceeds from the shares issued were contributed to COPLP in exchange for 1.5 million common units. COPT’s remaining capacity under the ATM Plan is an aggregate gross sales price of $110.9 million in stock sales.

During the nine months ended September 30, 2013, certain COPLP limited partners redeemed 310,889 common units in COPLP for common shares in COPT on the basis of one common share for each common unit.
