INFORMATION DOCUMENT

CAPITAL INCREASE TO BE CHARGED TO VOLUNTARY RESERVES

BANCO BILBAO VIZCAYA ARGENTARIA, S.A.

28^th September 2016

THIS DOCUMENT HAS BEEN PREPARED IN ACCORDANCE WITH ARTICLE 26.1.E) OF ROYAL DECREE 1310/2005, OF 4^th NOVEMBER, WHICH PARTIALLY DEVELOPS ACT 24/1988, OF 28^th JULY, ON THE SECURITIES EXCHANGE, WITH RESPECT TO THE ADMISSION OF SECURITIES FOR TRADING ON REGULATED SECONDARY MARKETS, PUBLIC BIDS OF SALE OR SUBSCRIPTION AND THE OFFERING CIRCULAR REQUIRED FOR SUCH PURPOSES.

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

The Annual General Shareholders’ Meeting of Banco Bilbao Vizcaya Argentaria, S.A. (“BBVA” or the “Bank”) held on 11^th March 2016 resolved, under section 3.2 of agenda item three, to increase the share capital of BBVA, to be charged to voluntary reserves, in accordance with the terms and conditions set out in the resolution (the “Capital Increase”), conferring authority on the Board of Directors of BBVA to execute the Capital Increase pursuant to article 297.1.a) of the consolidated text of the Corporate Enterprises Act, approved under Royal Legislative Decree 1/2010, of 2^nd July (the “Corporate Enterprises Act”), and to article 30.c) of BBVA Bylaws.

This information document (the “Information Document”) has been issued in accordance with article 26.1.e) of Royal Decree 1310/2005, of 4^th November, which partially develops Act 24/1988, of 28^th July, on the Securities Exchange, with respect to the admission of securities for trading on regulated secondary markets, public bids of sale or subscription and the offering circular required for such purposes, which provides that the preparation and publication of a prospectus related to the admission to listing of the shares issued as a consequence of the execution of a capital increase to be charged to reserves will not be necessary provided that “a document is made available containing information on the number and nature of the shares and the reasons for and details of the offer”. This Information Document is available on the Spanish National Securities Market Commission’s website (www.cnmv.es) and on the Bank’s website (www.bbva.com), where additional information of the Bank may be obtained.

The Capital Increase serves as an instrument for the implementation of the shareholder remuneration program named “Dividend Option”, which offers BBVA shareholders the opportunity to elect to receive all or part of their remuneration in ordinary newly-issued BBVA shares or in cash, at their choice.

The Dividend Option pursues the optimization and customization of the shareholder’s remuneration scheme, and therefore the shareholders benefit from more flexibility, since they will be able to adapt their remuneration to their preferences and personal situation.

The Dividend Option program works as follows:

Upon the execution of the Capital Increase, one (1) right of free allocation for each BBVA share will be assigned to whoever is accredited at 23:59 (Madrid (Spain) local time) on the day of the publication of the Capital Increase announcement in the Official Gazette of the Companies Registry (“Boletín Oficial del Registro Mercantil”) (envisaged for 30^th September 2016). These rights will be transferable and listed on the market during a fifteen (15) calendar day period. Once this period has elapsed, the rights will be automatically converted into ordinary newly-issued BBVA shares (except those which have been acquired and waived by BBVA as further explained below).

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

Under the Dividend Option program, each shareholder may opt from among the following alternatives¹:

Additionally, the above mentioned alternatives may be combined.

When no election is made, the holders of the rights of free allocation will receive the number of new BBVA shares corresponding to them, based on the number of rights of free allocation they may hold².

BBVA’s Board of Directors, at its meeting held on 28^th September 2016, approved the execution of the Capital Increase in accordance with the terms approved by the Annual General Shareholders’ Meeting of BBVA held on 11^th March 2016, under section 3.2 of agenda item three.

Pursuant to the formulas provided for in the referred resolution of the Annual General Shareholders’ Meeting, the Board of Directors of the Bank has established the terms and conditions of the Capital Increase as follows:

The maximum number of New Shares to be issued is the result of applying the formulas provided for in the resolution adopted by the Annual General Shareholders’ Meeting, considering that NOS (the number of old shares outstanding) is 6,480,357,925, that RMV (reference market value) is €530,000,000 and that RP (reference price) is €5.389³. On this basis, NAR (number of allocation rights) correspond to 66, in accordance with the formula indicated in the referred resolution (rounded up to the nearest next whole number):

NAR = RP x NOS / RMV = 5.389 x 6,480,357,925 / 530,000,000 = 66

Thus, the maximum number of New Shares to be issued is 98,187,241, in accordance with the formula established by the Annual General Shareholders’ Meeting (rounded down to the nearest next whole number):

New Shares = NOS / NAR = 6,480,357,925 / 66 = 98,187,241

However, the final number of New Shares and the final nominal value of the Capital Increase will depend on the number of rights of free allocation acquired by the Bank pursuant to its undertaking to acquire the rights of free allocation. BBVA will waive the rights of free allocation acquired pursuant to such undertaking and only those New Shares corresponding to the rights of free allocation which have not been acquired by BBVA pursuant to its undertaking will be issued.

The New Shares will be issued at their nominal value of forty-nine euro cents (€0.49) per New Share, without issuance premium.

One right of free allocation will be assigned for each BBVA share to whoever is accredited at 23:59 (Madrid (Spain) local time) on the day of the publication of the Capital Increase announcement in the Official Gazette of the Companies Registry (envisaged for 30^th September 2016).

4

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

In order to ensure that all the rights of free allocation can be effectively exercised and the number of New Shares to be issued is a whole number, BBVA has waived 19 rights corresponding to 19 own shares held in treasury stock.

The gross price at which BBVA undertakes to acquire each right of free allocation is €0.08 per right, in accordance with the formula provided for in the resolution adopted by the Annual General Shareholders’ Meeting (rounded off to the closest one-thousandth of a euro and, in the event of a half of a thousandth of a euro, by rounding up to the nearest next whole thousandth):

Purchase price = RP / (NAR+1) = 5.389 / (66+1) = €0.08

Accordingly, whoever is accredited, and wishes, to receive its remuneration in cash may sell its rights of free allocation to BBVA at a guaranteed fixed gross price of €0.08 per right.

BBVA’s undertaking to acquire rights of free allocation at this fixed price will be in effect until 13^th October 2016⁴.

The expected calendar⁵ for the execution of the Capital Increase is the following:

5

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

The rights of free allocation will be assigned to whoever is accredited at 23:59 (Madrid (Spain) local time) on the day of the publication of the Capital Increase announcement in the Official Gazette of the Companies Registry (envisaged for 30^th September 2016). The trading period of the rights will begin on the next trading day to the publication of that announcement and will have a term of fifteen (15) calendar days (envisaged from 3^rd to 17^th October 2016, both inclusive).

The option to receive cash or New Shares on the terms explained above, or to acquire in the market rights of free allocation sufficient and in the necessary proportion to subscribe for New Shares, will be available during the trading period of the rights of free allocation.

Those who are accredited to do so and wish to exercise the undertaking to acquire rights assumed by BBVA and receive cash at the guaranteed fixed price will need to communicate their decision no later than 13^th October 2016. This option is addressed exclusively to those who have been originally assigned such rights of free allocation and only with regard to the rights of free allocation initially allocated at such time; accordingly, the commitment will not be exercised in respect of any rights of free allocation acquired on the market.

When no election is made during the required period the holders of the rights of free allocation will receive the number of new BBVA shares corresponding to them, based on the number of rights of free allocation they may hold⁹.

To choose among the alternatives offered under the “Dividend Option” program, the holders of the rights of free allocation will have to contact the entities where their rights are deposited. Specifically:

6

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

BBVA shall not charge any fees or costs to those who opt to receive cash at the guaranteed fixed price in exercise of the undertaking to purchase right assumed by BBVA or to receive their corresponding New Shares. In case of sale of the rights on the market, BBVA shall charge the usual fees or costs pursuant to the applicable regulations.

The depository entities may charge the fees or costs related to the assignment of New Shares or the sale of rights pursuant to the applicable regulations.

The Capital Increase is carried out free of fees and costs in connection with the assignment of the New Shares, with the Bank assuming the costs for the issue, subscription, placing on the market, admission to listing and other related costs.

The New Shares to be issued under the Capital Increase will be ordinary shares with a par value of €0.49 each, of the same class and series and with the same rights as those currently outstanding.

The New Shares will be issued at an issue price of €0.49, which is without issuance premium, and will be represented by book entries, and the books will be managed by Sociedad de Gestión de los Sistemas de Registro, Compensación y Liquidación de Valores, S.A. Unipersonal (“Iberclear”), which performs such function along with its participating entities.

The Capital Increase is free of charge and, therefore, does not require any payment from the shareholders. The Capital Increase will be wholly charged to the freely distributable reserve named voluntary reserves, derived from retained earnings, which amounted to €6,970,821,339.21 as of 31^st December 2015.

The balance sheet used for purposes of the Capital Increase is that corresponding to 31^st December 2015, duly audited by Deloitte, S.L. as of 3^rd February 2016 and approved by the Annual General Shareholders’ Meeting on 11^th March 2016 under agenda item one.

At the end of the trading period for the rights of free allocation, the New Shares that have not been assigned will be held in deposit and made available to whoever can evidence its lawful ownership.

7

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

After three years, any New Shares whose allocation is still pending can be sold in accordance with article 117 of the Corporate Enterprises Act, on behalf of the interested parties. The net amount of such sale shall be held available to the parties concerned in the manner established by applicable legislation.

The New Shares will confer on their holders the right to participate in any distribution of corporate earnings paid out after the date on which they are recorded in the Iberclear accounting books, and in any net assets resulting from the Bank’s liquidation.

The Bank will apply for the listing of the New Shares on the Madrid, Barcelona, Bilbao and Valencia Stock Exchanges through the Spanish SIBE (Sistema de Interconexión Bursátil Español) electronic trading platform (Mercado Continuo), and shall take the steps and make the actions and arrangements that may be necessary or convenient and present any documents required before the competent bodies of the foreign stock exchanges where BBVA’s shares are traded, in order to list the New Shares finally issued on these exchanges. (BBVA shares are currently trading on the exchanges of London and Mexico; and via ADSs –American Depositary Shares– on the New York Exchange and on the Lima Exchange, due to the interchange agreement between both markets). Subject to the granting of the relevant authorizations, it is expected that the ordinary trading of the New Shares on the Spanish Stock Exchanges will begin on 26^th October 2016.

In general, the applicable tax regime in Spain for the Dividend Option is as follows:

For tax purposes, the vesting of the New Shares will be deemed to be the vesting of free-of-charge shares and, consequently, will not be considered as income for the purpose of Spanish personal income tax (“IRPF”), or for corporate income tax (“IS”) or for non-residents income tax (“IRNR”), whether or not acting through a permanent establishment in Spain.

The acquisition value of New Shares received and of the shares from which they originate will result from dividing the total cost by the corresponding number of shares, including both old and newly-issued shares. The seniority of such free-of-charge shares will be the same as the shares from which they originate.

In the event that the rights of free allocation are sold on the market, the amount obtained from the transfer of such rights will, in general, be subject to the following taxes:

8

						Disclaimer: This is a free translation of the original text in Spanish for information purposes only. In the event of any discrepancy, the Spanish original will prevail.

Thus only if the amount obtained from the transfer of the rights exceeds the acquisition value of the shares from which they originate will the difference be considered a capital gain for the transferor in the tax period in which the transfer takes place.

If whoever is accredited decides to exercise BBVA’s irrevocable undertaking to acquire the rights for cash, the tax regulations applicable to the amount obtained in the transfer to the Bank of the rights of free allocation will be equivalent to the tax regulations applicable to dividends distributed directly in cash, and therefore subject to the corresponding withholding tax, which currently stands at 19%.

The options, terms and procedures indicated in this Information Document may not be the same in respect of BBVA shares listed outside Spain, including in the form of BBVA ADSs. Shareholders holding such shares should consult the public announcements made and other documents published in the relevant jurisdictions.
