Noncontrolling Interest [Abstract] |
Noncontrolling Interests | 11. Noncontrolling Interests Noncontrolling interests relate to the interests in Boston Properties Limited Partnership not owned by Boston Properties, Inc. and interests in consolidated property partnerships not wholly-owned by the Company. As of December 31, 2016, the noncontrolling interests in Boston Properties Limited Partnership consisted of 17,079,511 OP Units, 904,588 LTIP Units (including 166,629 2012 OPP Units and 93,928 2013 MYLTIP Units), 474,415 2014 MYLTIP Units, 367,218 2015 MYLTIP Units and 473,360 2016 MYLTIP Units held by parties other than Boston Properties, Inc. Noncontrolling Interest—Redeemable Preferred Units On March 11, 2014, Boston Properties Limited Partnership notified the holders of the outstanding Series Two Preferred Units that it had elected to redeem all of such Series Two Preferred Units on May 12, 2014. As a result of Boston Properties Limited Partnership's election to redeem the units, as of May 12, 2014, the holders of all remaining 666,116 Series Two Preferred Units converted such units into an aggregate of 874,168 OP Units. The Series Two Preferred Units bore a preferred distribution equal to the greater of (1) the distribution which would have been paid in respect of the Series Two Preferred Unit had such Series Two Preferred Unit been converted into an OP Unit (including both regular and special distributions) or (2) 6.00% per annum on a liquidation preference of $50.00 per unit, and were convertible into OP Units at a rate of $38.10 per Preferred Unit (1.312336 OP Units for each Preferred Unit). Due to the holders’ redemption option existing outside the control of the Company, the Series Two Preferred Units were presented outside of permanent equity in the Company’s Consolidated Balance Sheets. On June 25, 2015, Boston Properties Limited Partnership redeemed the remaining 12,667 Series Four Preferred Units for cash totaling approximately $0.6 million, plus accrued and unpaid distributions. The Series Four Preferred Units bore a preferred distribution equal to 2.00% per annum on a liquidation preference of $50.00 per unit and were not convertible into OP Units. The holders of Series Four Preferred Units had the right, at certain times and subject to certain conditions set forth in the Certificate of Designations establishing the rights, limitations and preferences of the Series Four Preferred Units, to require Boston Properties Limited Partnership to redeem all of their units for cash at the redemption price of $50.00 per unit. Boston Properties Limited Partnership also had the right, at certain times and subject to certain conditions, to redeem all of the Series Four Preferred Units for cash at the redemption price of $50.00 per unit. In order to secure the performance of certain post-issuance obligations by the holders, all of such outstanding Series Four Preferred Units were subject to forfeiture pursuant to the terms of a pledge agreement and not eligible for redemption until the security interest was released and unless such security interest is released. On May 19, 2014, Boston Properties Limited Partnership released to the holders 319,687 Series Four Preferred Units that were previously subject to the security interest. On July 3, 2014, Boston Properties Limited Partnership redeemed such units for cash totaling approximately $16.0 million. On October 16, 2014, Boston Properties Limited Partnership released to the holders 27,773 Series Four Preferred Units that were previously subject to the security interest under the pledge agreement. On November 5, 2014, Boston Properties Limited Partnership redeemed such units for cash totaling approximately $1.4 million. Due to the holders’ redemption option existing outside the control of the Company, the Series Four Preferred Units were presented outside of permanent equity in the Company’s Consolidated Balance Sheets.

Noncontrolling Interest—Redeemable Interest in Property Partnership On October 4, 2012, the Company completed the formation of a joint venture, that owns and operates Fountain Square located in Reston, Virginia. The joint venture partner contributed the property valued at approximately $385.0 million and related mortgage indebtedness totaling approximately $211.3 million for a 50% interest in the joint venture. The Company contributed cash totaling approximately $87.0 million for its 50% interest, which cash was distributed to the joint venture partner. Pursuant to the joint venture agreement (i) the Company had rights to acquire the partner’s 50% interest and (ii) the partner had the right to cause the Company to acquire the partner’s interest on January 4, 2016, in each case at a fixed price totaling approximately $102.0 million in cash. The fixed price option rights were to expire on January 31, 2016. The Company was consolidating this joint venture due to the Company’s right to acquire the partner’s 50% interest. The Company recorded the noncontrolling interest at its acquisition-date fair value as temporary equity, due to the redemption option existing outside the control of the Company. The Company was accreting the changes in the redemption value quarterly over the period from the acquisition date to the earliest redemption date using the effective interest method. The Company was recording the accretion after the allocation of net income and distributions of cash flow to the noncontrolling interest account balance. On August 6, 2015, the parties amended the joint venture agreement to require the Company to acquire its partner’s 50% interest on September 15, 2015 for approximately $100.9 million in cash. On September 15, 2015, the Company acquired its partner’s 50% interest in the consolidated entity that owns Fountain Square for cash of approximately $100.9 million plus working capital and closing prorations and the partner’s share of assumed mortgage indebtedness totaling approximately $105.6 million. The following table reflects the activity of the noncontrolling interest—redeemable interest in property partnership in the Company’s Fountain Square consolidated entity for the years ended December 31, 2015 and 2013 (in thousands):

Noncontrolling Interest—Common Units During the years ended December 31, 2016 and 2015, 190,857 and 424,236 OP Units, respectively, were presented by the holders for redemption (including 103,847 and 65,192 OP Units, respectively, issued upon conversion of LTIP Units, 2012 OPP Units and 2013 MYLTIP Units) and were redeemed by Boston Properties, Inc. in exchange for an equal number of shares of Common Stock. Boston Properties Limited Partnership exercised its right under the terms of its partnership agreement to convert an aggregate of 625,043 eligible LTIP Units (including an aggregate of 32,349 2012 OPP Units and 2013 MYLTIP Units) into Common Units effective as of May 2, 2016. These conversions were effected solely for administrative efficiency and had no substantive impact on the rights of Boston Properties Limited Partnership or the holders of these LTIP Units, as the economic and other rights of the LTIP Units converted were substantively identical to those of the Common Units. In the future, Boston Properties Limited Partnership intends to convert LTIP Units (including 2012 OPP Units and MYLTIP Units) into Common Units promptly after they become eligible for conversion. The May 2016 conversions were, and future conversions will be, effected at the election of Boston Properties Limited Partnership and are without regard to the investment intentions of the holders of the units. At December 31, 2016, Boston Properties Limited Partnership had outstanding 474,415 2014 MYLTIP Units, 367,218 2015 MYLTIP Units and 473,360 2016 MYLTIP Units (See Note 17). Prior to the applicable measurement date (February 3, 2017 for 2014 MYLTIP Units (See Note 20), February 4, 2018 for 2015 MYLTIP Units and February 9, 2019 for 2016 MYLTIP Units), holders of MYLTIP Units will be entitled to receive per unit distributions equal to one-tenth (10%) of the regular quarterly distributions payable on an OP Unit, but will not be entitled to receive any special distributions. After the measurement date, the number of MYLTIP Units, both vested and unvested, that MYLTIP award recipients have earned, if any, based on the establishment of a performance pool, will be entitled to receive distributions in an amount per unit equal to distributions, both regular and special, payable on an OP Unit. On January 31, 2014, the measurement period for the Company’s 2011 OPP Unit awards expired and Boston Properties, Inc.’s TSR was not sufficient for employees to earn and therefore become eligible to vest in any of the 2011 OPP Unit awards. As a result, the Company accelerated the then remaining unrecognized compensation expense totaling approximately $1.2 million during the year ended December 31, 2014. Accordingly, all 2011 OPP Unit awards were automatically forfeited. On February 6, 2015, the measurement period for the Company’s 2012 OPP Unit awards ended and Boston Properties, Inc.’s TSR performance was sufficient for employees to earn and therefore become eligible to vest in a portion of the 2012 OPP Unit awards. The final outperformance pool was determined to be approximately $32.1 million, or approximately 80% of the total maximum outperformance pool of $40.0 million. As a result, 174,549 2012 OPP Units were automatically forfeited. On February 4, 2016, the measurement period for the Company’s 2013 MYLTIP awards ended and, based on Boston Properties, Inc.’s relative TSR performance, the final awards were determined to be 109.5% of target, or an aggregate of approximately $13.5 million. As a result, 205,762 2013 MYLTIP Units were automatically forfeited. The following table presents Boston Properties Limited Partnership’s distributions on the OP Units and LTIP Units (including the 2012 OPP Units and, after the February 4, 2016 measurement date, the 2013 MYLTIP Units) and its distributions on the 2013 MYLTIP Units (prior to the February 4, 2016 measurement date), 2014 MYLTIP Units, 2015 MYLTIP Units and 2016 MYLTIP Units (after the February 10, 2016 issuance date) paid in 2016:

A holder of an OP Unit may present the 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 must redeem the OP Unit for cash equal to the then value of a share of common stock of Boston Properties, Inc. Boston Properties, Inc. may, in its sole discretion, elect to assume and satisfy the redemption obligation by paying either cash or issuing one share of Common Stock. The value of the OP Units (not owned by Boston Properties, Inc. and LTIP Units (including the 2012 OPP Units and 2013 MYLTIP Units) assuming that all conditions had been met for the conversion thereof) had all of such units been redeemed at December 31, 2016 was approximately $2.3 billion based on the last reported price of a share of Common Stock on the New York Stock Exchange of $125.78 per share on December 31, 2016.

Noncontrolling Interests—Property Partnerships The noncontrolling interests in property partnerships consist of the outside equity interests in ventures that are consolidated with the financial results of the Company because the Company exercises control over the entities that own the properties. The equity interests in these ventures that are not owned by the Company, totaling approximately $1.5 billion at December 31, 2016 and approximately $1.6 billion at December 31, 2015, are included in Noncontrolling Interests—Property Partnerships on the accompanying Consolidated Balance Sheets. On October 30, 2014, the Company completed the sale of a 45% interest in each of 601 Lexington Avenue in New York City and Atlantic Wharf Office Building and 100 Federal Street in Boston for an aggregate gross sale price of approximately $1.827 billion in cash, less the partner’s pro rata share of the indebtedness collateralized by 601 Lexington Avenue. Net cash proceeds totaled approximately $1.497 billion, after the payment of transaction costs. In connection with the sale, the Company formed a limited liability company for each property with the buyer and will provide customary property management and leasing services to the joint ventures. 601 Lexington Avenue is a 1,669,000 square foot Class A office complex located in Midtown Manhattan. The property consists of a 59-story tower as well as a six-story low-rise office and retail building. The property is subject to existing mortgage indebtedness of approximately $712.9 million. The Atlantic Wharf Office Building is a 791,000 square foot Class A office tower located on Boston’s Waterfront. 100 Federal Street is a 1,323,000 square foot Class A office tower located in Boston’s Financial District. The transaction did not qualify as a sale of real estate for financial reporting purposes as the Company continues to effectively control these properties and thus will continue to account for the properties on a consolidated basis in its financial statements. The Company has accounted for the transaction as an equity transaction and has recognized noncontrolling interest in its consolidated balance sheets totaling approximately $849.0 million, which is equal to 45% of the aggregate carrying value of the total equity of the properties immediately prior to the transaction. The difference between the net cash proceeds received and the noncontrolling interest recognized, which was approximately $648.5 million, has not been reflected as a gain on sale of real estate in the Company’s consolidated statements of operations and has instead been reflected as an increase in Additional Paid-in Capital in the Company’s Consolidated Balance Sheets. On September 18, 2015, a consolidated entity in which the Company has a 50% interest completed the sale of its 505 9th Street, N.W. property located in Washington, DC for approximately $318.0 million, including the assumption by the buyer of approximately $117.0 million of mortgage indebtedness. 505 9th Street, N.W. is an approximately 322,000 net rentable square foot Class A office building. Net cash proceeds totaled approximately $194.6 million, of which the partners’ share was approximately $97.3 million. The Company recognized a gain on sale of real estate totaling approximately $199.5 million and $199.7 million for Boston Properties, Inc. and Boston Properties Limited Partnership, respectively, of which approximately $101.1 million was allocated to the outside partners and is included within Noncontrolling Interests in Property Partnerships in the Company’s Consolidated Statements of Operations. On December 10, 2015, the consolidated entity was dissolved and the Company reclassified the remaining noncontrolling interest balance totaling approximately $4.1 million to Accounts Payable and Accrued Expenses on the Consolidated Balances Sheets, of which approximately $0.2 million is outstanding at December 31, 2016. On May 12, 2016, the partners in the Company’s consolidated entity that owns Salesforce Tower located in San Francisco, California amended the venture agreement. Under the venture agreement, if the Company elects to fund the construction of Salesforce Tower without a construction loan (or a construction loan of less than 50% of project costs) and the venture has commenced vertical construction of the project, then the partner’s capital funding obligation shall be limited, in which event the Company shall fund up to 2.5% of the total project costs (i.e., 50% of the partner’s 5% interest in the venture) in the form of a loan to the partner. This loan would bear interest at the then prevailing market interest rates for construction loans. Under the amended agreement, the partners have agreed to structure this funding by the Company as preferred equity rather than a loan. The preferred equity contributed by the Company shall earn a preferred return equal to LIBOR plus 3.00% per annum and shall be payable to the Company out of any distributions to which the partner would otherwise be entitled until such preferred equity and preferred return have been repaid to the Company. As of December 31, 2016, approximately $4.3 million of preferred equity had been contributed by the Company to the venture. The following table reflects the activity of the noncontrolling interests—property partnerships for the years ended December 31, 2016, 2015 and 2014 (in thousands):
