By selling the 39,905 shares/voting rights of Wienerberger AG, CREF has therefore as of March 17, 2015 fallen below the 4% voting rights threshold.

2. CREF is exclusively managed by US-based TIAA-CREF Investment Management, LLC, which is wholly owned by US-based TIAA-CREF Asset Management LLC (a holding company), which is in turn wholly owned by TIAA. The voting rights of the above mentioned 4,670,228 shares (3.974%) in Wienerberger AG directly held by CREF can be exercised independently by TIAA-CREF Investment Management, LLC in its own name pursuant to a Policy Statement on Corporate Governance.

Therefore, the above mentioned 4,670,228 shares (3.974%) are attributable also to TIAA-CREF Investment Management, LLC pursuant to sec 92 (5) of the Austrian Stock Exchange Act. TIAA-CREF Investment Management, LLC has, thus, fallen below the 4% threshold as of March 17, 2015.

3. Since TIAA-CREF Investment Management, LLC - as outlined above - is an indirect wholly owned subsidiary of TIAA, the total voting rights of 3.974% in Wienerberger AG are attributable - pursuant to the requirements of the Austrian Stock Exchange Act - to TIAA which has fallen below the 4% threshold as of March 17, 2015.
