Item 8.01. Other Events.

On August 13, 2013, Whirlpool Corporation (the “Company”) announced that, on August 12, 2013, its wholly-owned subsidiary, Whirlpool (China) Investment Co., Ltd., a corporation organized under the laws of the People’s Republic of China (“Whirlpool China”), had reached agreements to acquire a 51 percent equity stake in Hefei Rongshida Sanyo Electric Co., Ltd., a joint stock company organized under the laws of the People’s Republic of China whose shares are listed and traded on the Shanghai Stock Exchange (“Hefei Sanyo”).

Pursuant to a Share Purchase Agreement (the “Share Purchase Agreement”) among Whirlpool China, SANYO Electric Co., Ltd. a corporation organized under the laws of Japan (“Sanyo Japan”), and SANYO Electric (China) Co., Ltd., a corporation organized under the laws of the People’s Republic of China (“Sanyo China”, and together with Sanyo Japan, the “Sellers”), Whirlpool China expects to purchase the 157,245,200 shares (or 29.51%) of Hefei Sanyo currently held by the Sellers (such transaction, the “Share Purchase”).

In addition, pursuant to a Share Subscription Agreement (the “Share Subscription Agreement”) between Whirlpool China and Hefei Sanyo, Whirlpool China expects to subscribe for 233,639,000 shares (which, together with shares purchased pursuant to the Share Purchase Agreement, will aggregate 51.0%) of Hefei Sanyo (subject to anti-dilution adjustments) issued pursuant to a private placement (such transaction, the “Share Subscription”). Pursuant to the Share Subscription Agreement and as required by the law of the People’s Republic of China, Whirlpool China will be prevented from selling any shares of Hefei Sanyo for 36 months following the close of the Share Subscription.

The aggregate purchase price for the Share Purchase and the Share Subscription is RMB 3.4 billion ($552 million based on the exchange rate as of August 9, 2013), subject, in each case, to certain adjustments if dividends are paid on the Hefei Sanyo shares. The purchase price for the Share Purchase is payable in USD based on the exchange rate as of August 9, 2013 and the purchase price for the Share Subscription is payable either in RMB or in USD based on the exchange rate on the payment date. The Company currently intends to fund the total consideration for the shares with cash on hand or other public or private debt financing depending on the timing of the closing and market conditions. The transaction also includes the commitment of capital and technical resources to enhance Hefei Sanyo’s research and development and product innovation.

The Share Purchase Agreement and Share Subscription Agreement contain representations and warranties regarding the shares of Hefei Sanyo, the Sellers’ and Hefei Sanyo’s authority, and customary covenants. The Share Purchase and Share Subscription are subject to customary closing conditions and the Share Purchase is subject to certain termination rights, including Sellers’ fiduciary termination right. In addition, the Share Purchase and the Share Subscription are subject to regulatory approvals by the Ministry of Commerce of the People’s Republic of China (foreign strategic investment and antitrust filing), the National Development and Reform Commission, the State-owned Assets Supervision and Administration Commission of the State Council, the China Securities Regulatory Commission (including waiver of a tender offer), the Hefei State-owned assets supervisory and administrative commission and formalities required by the State Administration of Foreign Exchange or its competent local branch and Hefei Sanyo shareholder approval. In addition, the Share Purchase and Share Subscription are cross-conditional on one another. Finally, under certain circumstances, including if the Share Purchase does not close by December 31, 2014 (or June 30, 2015 if the tax payment certificate has not yet been obtained) after the foreign strategic investment and antitrust approvals have been obtained, the Sellers will be entitled to retain the $20 million breakup fee paid by Whirlpool China. Both the Share Purchase and the Share Subscription are currently expected to close by the end of 2014.

The Company confirmed that its earnings and cash flow outlook for the full-year 2013 remain unchanged from the last update contained in its earnings release dated July 19, 2013.
