In connection with our negotiation of an agreement with an unrelated third-party for the sale of 100% fee-simple interests in two office properties and one development site located in Washington, D.C., which sale was consummated in July 2019, we determined the book value of such properties exceeded their estimated fair value and recognized an impairment charge of $66,200,000 during the three months ended March 31, 2019 under the held-and-used impairment model. Following our signing of the agreement for the sale of the aforementioned properties and our receipt of a non-refundable deposit in respect of their sale in June 2019, such properties were classified as held for sale as of June 30, 2019 and we recognized an additional impairment charge of $2,800,000 under the held-for-sale impairment model. Our determination of the fair values of these properties was based on negotiations with the third-party buyer and the contract sales price.
