SENIOR HOUSING PROPERTIES TRUST (NASDAQ:SNH) Files An 8-K Regulation FD Disclosure

Item 7.01. Regulation FD Disclosure.

A copy of the press release that we issued announcing the
transactions described in Item 8.01 of this Current Report on
Form8-K is attached as Exhibit99.1.

Item 8.01. Other Events.

On March24, 2017, we entered into a joint venture with a
sovereign institutional investor for our property located in
Boston, Massachusetts which consists of two buildings primarily
leased to Vertex Pharmaceuticals,Inc. The investor has
contributed approximately $261 million for a 45% equity interest
in the joint venture, and we have retained a 55% equity interest
in the joint venture. The investment amount is based upon a
property valuation of $1.2 billion, less $620 million of existing
secured debt on the property. We used the net proceeds from this
transaction to repay a portion of the amounts outstanding under
our revolving credit facility.

We will continue to control this property because our partner in
this joint venture is a passive financial investor. Accordingly,
we expect to consolidate the operating results of this joint
venture in our financial statements and account for the investors
minority equity interest in the joint venture as a
non-controlling interest for financial reporting purposes.
