Item 8.01. Other Events.

On February 1, 2013, MetLife, Inc., a Delaware corporation (“MetLife”), entered into a Transaction Agreement (the “Transaction Agreement”) with Banco Bilbao Vizcaya Argentaria S.A. (“BBVA”) and BBVA Inversiones Chile S.A. (“BBVA Inversiones,” and together with BBVA, the “BBVA Sellers”), pursuant to which MetLife, through one or more wholly-owned subsidiaries, has agreed to commence one or more tender offers in Chile and the United States (the “Offer”) to purchase all of the outstanding ordinary shares (“Ordinary Shares”) and American Depositary Shares (“ADS”) of Administradora de Fondos de Pensiones Provida S.A., a pensions fund administrator incorporated under the laws of Chile (“Provida”), and the BBVA Sellers have agreed to transfer all of the Ordinary Shares and ADS owned by such BBVA Sellers to MetLife (the “Transaction”).

Pursuant to the Transaction Agreement, subject to the satisfaction or waiver of the conditions set forth therein, and assuming all of the outstanding Ordinary Shares and ADS not held by the BBVA Sellers are also validly tendered into the Offer and not withdrawn, MetLife would pay approximately U.S.$ 2.0 billion in the aggregate for all of the outstanding Ordinary Shares and ADS (at a per Ordinary Share purchase price of U.S.$ 6.0365, or, in the case of each ADS, at a purchase price equal to such amount multiplied by 15). The aggregate purchase price will be subject to upward adjustment by U.S.$ 400,000 per day (assuming all of the Ordinary Shares and ADS not held by the BBVA Sellers are also validly tendered into the Offer and not withdrawn) from the date of Provida’s most recent month-end balance sheet available immediately prior to the commencement of the Offer until the date of publication of the Offer’s notice of results.

MetLife expects to fund the Transaction from available cash on hand, and the Transaction is not subject to a financing condition.

The Transaction Agreement requires, as a condition to commencement of the Offer, that Provida’s indirect minority equity interest in Administradora de Fondos de Pensiones Horizonte S.A., a pensions fund administrator incorporated under the laws of Peru, will be transferred to an affiliate of the BBVA Sellers. In addition, BBVA has disclosed pursuant to the Current Report on Form 6-K filed by BBVA with the SEC on January 9, 2013, that the sale of Provida’s indirect minority equity interest formerly owned in Administradora de Fondos para el Retiro Bancomer S.A. de C.V., a pensions fund administrator incorporated under the laws of Mexico, to Afore XXI Banorte, S.A. de C.V. was completed on such date. The proceeds, net of taxes, received by Provida in connection with these two sales are expected to be distributed to shareholders of Provida prior to the closing of the Offer. Pursuant to the Transaction Agreement, Provida will also be permitted to approve the distribution, prior to the commencement of the Offer, of an annual dividend in respect of 2012 fiscal year profits and a dividend of certain excess cash amounts of Provida as calculated pursuant to the Transaction Agreement.

The commencement of the Offer is subject to the satisfaction of certain conditions, including the receipt of requisite regulatory approvals from the Chilean regulatory agency for pension fund administrators (Superintendencia de Pensiones), the Ecuadorian Superintendence of Control of Market Power (Superintendencia de Regulación y Control del Poder de Mercado) and, if required, the approvals from the Chilean Ministry of Labor and the Chilean Ministry of Finance. The closing of the Offer is also subject to the satisfaction of certain conditions, including that all of the Ordinary Shares and ADS owned by the BBVA Sellers are transferred to MetLife.

Prior to the closing of the Offer, BBVA will be required to cause Provida and its subsidiaries to conduct their business, preserve substantially intact their business organizations, and maintain business relationships, in each case in the ordinary course consistent with past practice. BBVA has also agreed to ensure that Provida and its subsidiaries comply with certain other operating covenants between the date of the Transaction Agreement and the closing of the Offer.

From and after the date of the Transaction Agreement until the closing of the Offer, the BBVA Sellers have agreed not to, among other things, initiate, propose, solicit, encourage or assist in or knowingly facilitate the making of any competing acquisition proposal nor tender into competing tender offers.

For a period of three years following the closing of the Offer, BBVA has agreed not to directly or indirectly engage in any business in Chile or Ecuador with respect to certain products or services requiring licensing as a pensions fund administrator in those countries that are being provided by Provida or its subsidiaries as of the closing of the Offer, subject to certain exceptions. In addition, for a period of three years following the closing of the Offer, BBVA has agreed not to directly or indirectly solicit for employment or hire any investment professionals or officers or directors of Provida or its subsidiaries, and, starting from the date of the Transaction Agreement and ending three years following the closing of the Offer, MetLife has agreed not to directly or indirectly solicit for employment or hire any investment professionals or officers or directors of BBVA or its subsidiaries located in Chile or Ecuador with whom MetLife has come into contact in connection with the Transaction, in each case, subject to certain customary exceptions.

The Transaction Agreement may be terminated under certain circumstances, including by either MetLife or BBVA due to the failure to consummate the Transaction on or prior to the date that is ten months after the date of the Transaction Agreement.

The Transaction Agreement provides that, following the closing of the Offer, the BBVA Sellers will indemnify MetLife for certain losses as described therein, including losses related to breaches of the BBVA Sellers’ representations, warranties and covenants.
