Real Estate	Note 3. Real Estate Land Parcel Acquisition On August 8, 2018, the Company purchased a land parcel adjacent to its Riverview Plaza property, located in Philadelphia, Pennsylvania. The purchase price for the land parcel was $1.0 million, which was comprised of $25,000 in cash and approximately 208,000 OP Units (based on the market price of the Company’s common stock). Shopping Center Acquisition On August 21, 2018, the Company entered into a deed of lease for Senator Square, a shopping center located in Washington, D.C. The deed of lease conveys fee title in the buildings to the Company and contains future options to acquire fee title in the land at its then fair-value. This lease is presented in the Company’s financial statements as two separate components as follows: (1) a$5.7 million capital lease obligation for the fee interest in the buildings, and (2) an operating lease for the land. The capital lease obligation was computed through the date of the Company’s first purchase option, as discussed below, and reflects an interest rate of 5.3%. The lease initially requires monthly payments of $75,000 through maturity in August 2117 unless the Company exercises one of its options to acquire the land. The first such option will be available between the 25th and 33rd anniversaries of the lease, depending on certain property benchmarks, with additional purchase options every 10 years thereafter during the lease term. The lease also provides for 1.5% annual increases which begin on approximately the 8th anniversary of the lease, depending on the aforementioned property benchmarks. In addition, at the time the Company’s first purchase option becomes available, the lease payments will be adjusted to the greater of then fair-value or the current payment amount. The lease payments are subject to similar adjustments at the 25th and 50th anniversaries of such first purchase option. The Company has also issued a $3.5 million interest only mortgage note receivable to the lessor of Senator Square, which bears interest at 4.5% per annum. The maturity date of this mortgage note can range from 26.5 years to 34.5 years from the date of issuance, based on the aforementioned property benchmarks. Dispositions On August 28, 2018, the Company sold Mechanicsburg Center, located in Mechanicsburg, Pennsylvania. The sales price for the property was $16.1 million, which resulted in a gain on sale of $4.9 million, which has been included in continuing operations in the accompanying consolidated statements of operations. On September 28, 2018, the Company sold West Bridgewater Plaza, located in West Bridgewater, Massachusetts. The sales price for the property was $3.5 million.

Impairment charges/reversals, if applicable, are based on a comparison of the carrying values of the properties with either (1) actual sales prices less costs to sell for properties sold, or contract amounts for properties in the process of being sold, (2) estimated sales prices, less costs to sell, based on discounted cash flow or income capitalization analyses, if no contract amounts are being negotiated (see Note 4 - “Fair Value Measurements”), or (3) with respect to land parcels, estimated sales prices, less costs to sell, based on comparable sales completed in the selected market areas.

The projected undiscounted cash flows of each property reflects that the carrying value of each real estate investment would be recovered. However, as a result of the properties’ meeting the “held for sale” criteria, such properties were written down to the lower of their carrying value and estimated fair values less costs to sell. As of September 30, 2018, Carll’s Corner, located in Bridgeton, New Jersey, and Maxatawny Marketplace, located in Maxatawny, Pennsylvania, have been classified as “real estate held for sale” on the accompanying consolidated balance sheet.
