[1] The change in the Foxtel investment for the nine months ended March 31, 2015 was primarily due to the impact of foreign currency fluctuations.

[2] In July 2014, REA Group purchased a 17.22% interest in iProperty Group Limited (ASX: IPP) ("iProperty") for total cash consideration of approximately $100 million. iProperty has online property advertising operations primarily in Malaysia, Indonesia, Hong Kong, Macau, Thailand and Singapore. In December 2014, REA Group sold Squarefoot, its Hong Kong based business, to iProperty in exchange for an additional 2.2% interest in iProperty. Upon completion of the transaction and including an acquisition of additional shares of iProperty in October 2014, REA Group owns an approximate 19.9% interest in iProperty, and retroactively applied the equity method of accounting in the second quarter of fiscal 2015 in accordance with ASC 323, "Investments - Equity Method and Joint Ventures."

[3] In May 2012, Foxtel purchased Austar United Communications Ltd. The transaction was funded by Foxtel bank debt and Foxtel's shareholders made pro rata capital contributions in the form of subordinated shareholder notes based on their respective ownership interests. The Company's share of the subordinated shareholder notes was approximately A$451 million ($350 million and $425 million as of March 31, 2015 and June 30, 2014, respectively). The subordinated shareholder note can be repaid beginning in July 2022 provided that Foxtel's senior debt has been repaid. The subordinated shareholder note has a maturity date of July 15, 2027, with interest of 12% payable on June 30 each year and at maturity. Upon maturity, the principal advanced will be repayable.

[4] In March 2015, the Company agreed to increase its 4.8% interest in APN News and Media Limited ("APN") to 14.99% for a purchase price of approximately $70 million. APN operates a portfolio of Australian and New Zealand radio and outdoor media assets and small regional print interests. The acquisition is subject to regulatory approval and is expected to be completed in the fourth quarter of fiscal 2015. If regulatory approval is not obtained, the APN shares will be sold to alternative purchasers with the Company bearing the economic loss if the sales price is lower than the Company's agreed purchase price and benefiting from the gain if the sales price is higher.

The transaction was funded primarily through additional contributions by SEEK Asia shareholders. The Company's share of the funding contribution was approximately $60 million and the Company continues to hold a 12.1% investment in SEEK Asia following the transaction.
