Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | 1. Organization Boston Properties, Inc., a Delaware corporation, is a fully integrated, self-administered and self-managed real estate investment trust (“REIT”). Boston Properties, Inc. is the sole general partner of Boston Properties Limited Partnership and at December 31, 2015 owned an approximate 89.5% (89.5% at December 31, 2014) general and limited partnership interest in Boston Properties Limited Partnership. Unless stated otherwise or the context requires, the “Company” refers to Boston Properties, Inc. and its subsidiaries, including Boston Properties Limited Partnership, its operating partnership, and its consolidated subsidiaries. Partnership interests in Boston Properties Limited Partnership are denominated as “common units of partnership interest” (also referred to as “OP Units”), “long term incentive units of partnership interest” (also referred to as “LTIP Units”) or “preferred units of partnership interest” (also referred to as “Preferred Units”). In addition, in February 2012, Boston Properties Limited Partnership issued LTIP Units in connection with the granting to employees of outperformance awards (also referred to as “2012 OPP Units”). On February 6, 2015, the measurement period for Boston Properties Limited Partnership’s 2012 OPP Unit awards expired and Boston Properties, Inc.’s total stockholder return (“TSR”) was sufficient for employees to earn and therefore become eligible to vest in a portion of the 2012 OPP Unit awards (See Note 17). In February 2013, February 2014 and February 2015, Boston Properties, Inc. issued LTIP Units in connection with the granting to employees of multi-year, long-term incentive program (“MYLTIP”) awards (also referred to as “2013 MYLTIP Units,” “2014 MYLTIP Units” and “2015 MYLTIP Units,” respectively, and collectively as “MYLTIP Units”). Because the rights, preferences and privileges of MYLTIP Units differ from other LTIP Units granted to employees as part of the annual compensation process (including, as of February 6, 2015, the 2012 OPP Units), unless specifically noted otherwise, all references to LTIP Units exclude MYLTIP Units when and until they are earned (See Notes 11, 17 and 20). Unless specifically noted otherwise, all references to OP Units exclude units held by Boston Properties, Inc. A holder of an OP Unit may present such OP Unit to Boston Properties Limited Partnership for redemption at any time (subject to restrictions agreed upon at the time of issuance of OP Units to particular holders that may restrict such redemption right for a period of time, generally one year from issuance). Upon presentation of an OP Unit for redemption, Boston Properties Limited Partnership is obligated to redeem such OP Unit for cash equal to the value of a share of common stock of Boston Properties, Inc. (“Common Stock”) at such time. In lieu of a cash redemption, Boston Properties, Inc. may elect to acquire such OP Unit for one share of Common Stock. Because the number of shares of Common Stock outstanding at all times equals the number of OP Units that Boston Properties, Inc. owns, one share of Common Stock is generally the economic equivalent of one OP Unit, and the quarterly distribution that may be paid to the holder of an OP Unit equals the quarterly dividend that may be paid to the holder of a share of Common Stock. At the time of an award, LTIP Units do not have full economic parity with OP Units or Common Stock, but can achieve parity over time upon the occurrence of specified events in accordance with partnership tax rules. LTIP Units, whether vested or not, will receive the same quarterly per unit distributions as OP Units, which equal per share dividends on Common Stock (See Note 12). At December 31, 2015, there was one series of Preferred Units outstanding (i.e., Series B Preferred Units). The Series B Preferred Units were issued to Boston Properties, Inc. in connection with its issuance of 80,000 shares (8,000,000 depositary shares each representing 1/100th of a share) of 5.25% Series B Cumulative Redeemable Preferred Stock (the “Series B Preferred Stock”). Boston Properties, Inc. contributed the net proceeds from the offering to Boston Properties Limited Partnership in exchange for 80,000 Series B Preferred Units having terms and preferences generally mirroring those of the Series B Preferred Stock (See Note 12). Properties At December 31, 2015, the Company owned or had interests in a portfolio of 168 commercial real estate properties (the “Properties”) aggregating approximately 46.5 million net rentable square feet, including eleven properties under construction/redevelopment totaling approximately 4.6 million net rentable square feet. At December 31, 2015, the Properties consist of:
• | 158 office properties, including 127 Class A office properties (including nine properties under construction/redevelopment) and 31 Office/Technical properties;
• | one hotel;
• | five retail properties; and
• | four residential properties (including two properties under construction)
The Company owns or controls undeveloped land parcels totaling approximately 457.1 acres. The Company considers Class A office properties to be centrally located buildings that are professionally managed and maintained, attract high-quality tenants and command upper-tier rental rates, and that are modern structures or have been modernized to compete with newer buildings. The Company considers Office/Technical properties to be properties that support office, research and development, laboratory and other technical uses. The Company’s definitions of Class A Office and Office/Technical properties may be different than those used by other companies. Net rentable square feet amounts are unaudited. Basis of Presentation Boston Properties, Inc. does not have any other significant assets, liabilities or operations, other than its investment in Boston Properties Limited Partnership, nor does it have employees of its own. Boston Properties Limited Partnership, not Boston Properties, Inc., generally executes all significant business relationships other than transactions involving securities of Boston Properties, Inc. All majority-owned subsidiaries and joint ventures over which the Company has financial and operating control and variable interest entities (“VIEs”) in which the Company has determined it is the primary beneficiary are included in the consolidated financial statements. At December 31, 2015 and 2014, the Company did not have any VIEs. All significant intercompany balances and transactions have been eliminated in consolidation. The Company accounts for all other unconsolidated joint ventures using the equity method of accounting. Accordingly, the Company’s share of the earnings of these joint ventures and companies is included in consolidated net income.
