Noncontrolling Interest [Abstract] |
Non-Controlling Interests | 12. Non-Controlling Interests Under the Company’s UPREIT structure, entities and individuals can contribute their properties in exchange for membership interests in the Operating Company. Properties contributed as part of UPREIT transactions were valued at $10,498, $7,190 and $57,583 during the years ended December 31, 2017, 2016, and 2015, respectively, which represents the estimated fair value of the properties contributed, less any assumed debt. The cumulative amount of UPREIT properties contributed, less assumed debt, amounted to $112,949, $102,451 and $95,261 through December 31, 2017, 2016 and 2015, respectively. In exchange for the properties contributed, 1,551, 1,427, and 1,330 non-controlling membership units were issued and outstanding, representing a 7.6%, 8.6% and 10.4% interest in the Operating Company at December 31, 2017, 2016 and 2015, respectively. The Operating Company’s membership units are economically equivalent to the Corporation’s common stock and, subject to certain restrictions, are convertible into the Company’s common stock at the option of the respective unit holders on a one-to-one basis. The membership units are not redeemable for cash in any circumstance and are therefore considered to be permanent equity. Exchanges of membership units of the Operating Company held by non-controlling interest holders are recorded by reducing non-controlling interest on a historical cost basis with a corresponding increase in common stock and additional paid-in capital. There were 37 membership units exchanged for 37 shares of common stock for a value of $2,986 during 2017. There were no UPREIT units exchanged for common stock during 2016 and 2015. Holders of the membership units in the Operating Company do not have voting rights at the Corporation level. The Company recognized rental income related to properties contributed as part of UPREIT transactions in the amount of $13,153, $11,843 and $5,259 for the years ended December 31, 2017, 2016 and 2015, respectively.
