From time to time the Company receives incentives from the landlord including tenant improvement discounts and periods of free rent. The Company recognizes the effects of these rent escalations, tenant improvement discounts and periods of free rent on a straight-line basis over the lease terms. Contingent Liabilities As part of the Office acquisitions completed in 2009, the Company recorded contingent liabilities to recognize an estimated amount to be paid as part of the acquisition agreements. These contingent liabilities are recorded at estimated fair values as of the date of acquisition, are payable beginning after four years from the acquisition date and are calculated at a multiple of the then trailing twelve-months operating cash flows. The Company remeasures the contingent liability to fair value each reporting date until the contingency is resolved. Any changes to the fair value are recognized into the income statement when determined. During the quarter ended September 30, 2013, the Company remeasured and reduced the value of contingent liabilities by $196,000 and recognized this amount as other income for the quarter. The $401,000 of contingent liabilities became payable as of September 30,
