Daiwa Office Investment Corporation (the “Investment Corporation”) hereby gives notice that Daiwa Real Estate Asset Management Co. Ltd. (the “Asset Manager”), to which the Investment Corporation entrusts the management of its assets, decided on the changes in its organization and key employees at the board of directors’ meeting held today.

1. Changes in Organizational Structure

   1. Description of Change

      The Asset Manager decided on the following changes in organization at its board of directors’ meeting held today.

      The Asset Manager is entrusted with asset management operations of five investment corporations, namely, listed REITs, Daiwa Office Investment Corporation (DOI / the Investment Corporation) and Daiwa Securities Living Investment Corporation (DLI), and private REITs, Daiwa Residential Private Investment Corporation (DRP), Daiwa Hotel Private Investment Corporation (DHP) and Daiwa Securities Logistics Private Investment Corporation (DLP).

      ‌Among the multiple investment corporations mentioned above, DLP has seen a halt in the rise of vacancy rates, primarily in logistics facilities in the Tokyo metropolitan area, since the COVID-19 pandemic. Given signs of a changing external environment for the real estate rental market going forward, including tightening supply-demand conditions and the prospect of rent increases driven by inflation, the Asset Manager has placed increased emphasis on management that maximizes unitholder value through internal growth.

      ‌In light of these external environmental changes, the Asset Manager will integrate the investment management divisions of DRP and DLP with the aim of further strengthening the asset management capabilities and improving operational efficiency.
