Preferred Return Terms	In 2013, we recorded an impairment loss of $1,813 related to the Courtyard, Norwich, CT, one of the properties owned by Mystic Partners, LLC.  Mystic Partners, LLC transferred the title to the property to the lender during the year ended December 31, 2014.  As we did not anticipate recovering our investment balance in this asset, we reduced the portion of our Mystic Partners, LLC investment related to this property to $0 as of December 31, 2013. On February 1, 2013, the Company closed on the sale of its interest in one of the unconsolidated joint venture properties owned in part by Mystic Partners, LLC to its joint venture partner. As our investment in this unconsolidated joint venture equated the net proceeds distributed to us, we did not record a gain or loss in connection with the sale of this hotel.The Mystic Partners, LLC joint venture agreement provides for an 8.5% non-cumulative preferred return based on our contributed equity interest in the venture. Cash distributions will be made from cash available for distribution, first, to us to provide an 8.5% annual non-compounded return on our unreturned capital contributions and then to our joint venture partner to provide an 8.5% annual non-compounded return of their unreturned contributions. Any remaining cash available for distribution will be distributed to us 10.5% with respect to the net cash flow from the Hartford Marriott, 7.0% with respect to the Hartford Hilton and 56.7%, with respect to the remaining property.
