Hearst Tower

The $250 million, or $257 per square foot, purchase price of Hearst Tower represents a significant discount to replacement cost. The building is currently 94% leased with no material expirations until 2017. The property is expected to generate cash net operating income of approximately $17.5 million during the first year of the Company’s ownership period. The purchase of Hearst Tower was financed with the cash received from TPG combined with borrowings on the Company’s credit facility. While the property is currently unencumbered, the Company expects to obtain financing on the property to provide capital for future investment opportunities.

Non-Core Asset Sales

The Pinnacle at Jackson Place and Parking at Jackson Place are both located in the central business district of Jackson and total 271,000 square feet. Parkway sold the two assets for a combined purchase price of $29.5 million, and the buyer assumed the $29.5 million non-recourse mortgage loan secured by The Pinnacle at closing.
