Download XLSThe Fund’s investment properties are valued by an external valuation expert on a quarterly basis. The external valuation expert is changed every three years. On 31 December 2014, these properties were revalued by independent professionally qualified valuation experts who hold a recognised relevant professional qualification and had recent experience in the locations and categories of the investment properties valued. The carrying values of investment property as at 31 December 2014, and 1 January 2014, are in line with the valuations reported by the external valuation experts. 
Since the accounting effect of lease incentives granted is included under non-current assets the recognised amount € 373,000 (2013: € 336,000) is deducted from the total fair value of investment properties.

Download XLSThe vacancy rate showed an upward trend due to some bankruptcies.
The total gain (loss) for the year included an unrealised gain of € 2,465 (2013: € 921) relating to investment properties that are measured at fair value at the end of the reporting period.
The valuation of the investment properties takes into account a rent-free period/rent incentives ranging from 1 to 3 months after occupation.
As at 31 December 2014, the Fund had unprovisioned contractual obligations for future repairs and maintenance of € 0.1 million (2013: € 0.2 million).
Direct operating expenses recognised in profit or loss include € 0.1 million (2013: € 0.2 million) relating to vacant investment property. Investment property includes buildings held under finance leases. The carrying amount is € nil (2013: € nil).
Sensitivity analysis
The appraisal of the portfolio implies a net initial yield of 5.9% (2013: 6.1%). If the yields used for the appraisals of investment properties on 31 December 2014 had been 100 basis points higher (2013: 100 basis points higher) than was the case at that time, the value of the investments would have been 14.7 % lower (2013: 14.2% lower). In this situation, the Fund’s shareholders’ equity would have been € 92 million lower (2013: € 70 million lower).
