Index published July 23, 2010 (referring to April 2010), amended July 23, 2010

In accordance with those corrections, partial amendments have been made to the index.

Index published June 30, 2010 (referring to March 2010), amended June 30, 2010

Of the NOI (Net Operating Income) of the individual real estate used to calculate the index published May 31, the data of Nippon Commercial Investment Corporation for the 8th period was different from the value in its disclosed material, as depreciation expenses had been added to the value written as the NOI in the disclosed material. Therefore, the data was amended to the NOI in the disclosed material. In association with this amendment, some indices will be changed.

As Nippon Commercial Investment Corporation presents income or losses from leasing after depreciation expenses as NOI in its disclosures, we currently use the NOI value in the disclosed material without modification for the calculation of the index. The amendment above was made in compliance with this policy.

However, as a result of considering the policy in light of the purpose of the NOI assumed for the calculation of the index of the ARES, we have judged that it is more reasonable to use income or losses from leasing before depreciation expenses as the NOI.

In line with this judgment, we plan to change the policy when publishing the index in July, so that for properties owned by Nippon Commercial Investment Corporation, we will retroactively use the value that adds depreciation expenses to income or losses from leasing after depreciation expenses as the NOI in calculating the Index, instead of the value (income or losses from leasing after depreciation expenses) that Nippon Commercial Investment Corporation publishes as the NOI.

Due to errors being found in the individual real estate data used to calculate the index, the corrections indicated below have been made.

In accordance with those corrections, partial amendments have been made to the index.
