For and behalf of the Board of Directors

P. Sanker

Senior General Manager (Legal) & Company Secretary

Mumbai, May 5, 2017

EXPLANATORY STATEMENT UNDER SECTION 102(1) OF THE COMPANIES ACT, 2013

Item Nos. 1, 2 and 3

The equity shares of your Bank are listed and actively traded on the National Stock Exchange of India Limited and BSE Limited, and American Depository Shares (ADS) are listed and actively traded on New York Stock Exchange. The Board of Directors of the Bank at its Meeting held on May 3, 2017 considered and approved a bonus issue of 1 (one) equity share for every 10 (ten) existing equity share held and consequent to creation of bonus equity shares underlying ADS, a bonus issue of one ADS for every ten existing ADS held, respectively, as on the Record Date (as indicated in the resolution) subject to approval of the Members and any other statutory and regulatory approvals as applicable. The ratio of equity shares underlying the ADS held by an ADS holder would remain unchanged.

The bonus issue of equity shares would, inter alia, require appropriate adjustments with respect to all the stock options of the Bank under The Employee Stock Option Scheme 2000, pursuant to the SEBI (Share Based Employee Benefits) Regulations, 2014 and any amendments thereto from time to time, such that all stock options which are available for grant and those already granted but not exercised as on Record Date shall be proportionately adjusted. The bonus issue would also require appropriate adjustments to the ADSs considering the terms of the ADSs which entitles an ADS holders to two equity shares for one Depository Receipt (DR) held by them.

Presently, the Authorised Share Capital of your Bank is Rs. 1775,00,00,000/- (Rupees One Thousand Seven Hundred and Seventy Five Crores) divided into:

i. 637,50,00,000 (Six Hundred Thirty Seven Crores and Fifty Lakhs) equity shares of Rs. 2 (Rupees Two) each,

ii. 150,00,000 (One Crore Fifty Lakhs) shares of Rs. 100 (Rupees One Hundred) each which shall be of such class and with rights, privileges, conditions or restrictions as may be determined by the company in accordance with these presents and subject to the legislative provisions for the time being in that behalf, and

iii. 350 (Three Hundred and Fifty) preference shares of Rs. 100,00,000 (Rupees One Crore) each.

It is necessary to increase the quantum of authorised share capital to facilitate issuance of bonus shares and for future requirements if any. Hence it is proposed to increase the Authorised Share Capital to Rs. 2500,00,00,000 (Rupees Two thousand five hundred crores only) divided into 1000,00,00,000 equity shares of Rs. 2 each, 150,00,000 shares of Rs. 100 each and 350 preference shares of Rs. 100,00,000 each by creation of additional 362,50,00,000 equity shares of Rs. 2 each.

The increase in Authorised Share Capital as aforesaid would require consequential amendments to the existing capital clauses in the Memorandum and Articles of Association of the Bank.

The increase in Authorised Share Capital and amendments to relevant clauses of the Memorandum and Articles of Association of the Bank and issue of bonus equity shares are subject to Members’ approval in terms of Sections 13,14, 61 and 63 of the Companies Act, 2013 and any other applicable statutory and regulatory approvals.

Accordingly, the resolutions 1, 2 and 3 of the Postal Ballot Notice seek Members’ approval for increase in Authorised share capital and consequential amendments to Memorandum of Association and Articles of Association of the Bank and capitalisation of the amount standing to the credit of Securities Premium Account for the purpose of issue of bonus equity shares on the terms and conditions set out in the resolution.

The Board recommends the resolutions 1, 2 and 3 for approval of the Members.

Members may kindly note that the Bonus shares/ consequent ADS proposed to be issued, subject to approval of Members will not be eligible for dividend in respect of financial year ending March 31, 2017 which is being proposed at the forthcoming Annual General Meeting of the Bank.

None of the Directors or Key Managerial Personnel of the Bank or their relatives are in any way concerned or interested, financially or otherwise in the resolutions 1, 2 and 3 of the Notice except to the extent of their shareholding and outstanding employee stock options in the Bank.

Item No. 4

SEBI (Share Based Employee Benefits) Regulations, 2014 defines Exercise Period as the time period after vesting within which an employee should exercise his/her right to apply for shares against the vested options. Members vide Postal Ballot resolution passed on April 22, 2016 approved the amendment to the ‘Employees Stock Option Scheme – 2000 ’ (ESOS scheme) of the Bank relating to the definition of Exercise Period as under :

“Exercise Period means the period commencing from the date of vesting of Options and ending on the tenth anniversary of the date of vesting of Options.”

It is now proposed to amend this definition of Exercise Period as under:

“Exercise Period means the period commencing from the date of vesting and will expire on completion of such period not exceeding ten years from the date of vesting of Options as may be determined by the Board Governance, Remuneration & Nomination Committee (“BGNRC”) for each grant”.

The amendment is intended to cover only future grants to be made and would come into effect only after approval by Members and will not cover grants already made. There is no incremental Exercise Period being granted or proposed. The present definition provides for a fixed term Exercise Period of ten years and does not allow flexibility to align the Exercise Period of future grants to reflect the time horizon of short term and long term strategies of the Bank. The amendment would enable grants to be made with appropriate Exercise Period(s) for each grant after vesting to better align (i) employee efforts to the articulated strategy; and (ii) the compensation payout schedules for senior management to the time horizon of risks.

As per the SEBI Regulations, any variation to the terms of the Scheme requires the approval of Members by way of a special resolution. There are no other changes to the existing terms of the Scheme. None of the Directors or Key Managerial Personnel of the Bank including their relatives are, in any way, concerned or interested, financially or otherwise, in the proposed resolution except to the extent of grant of stock options to them, if any, under the said Scheme.

A copy of the draft amended Scheme would be available for inspection at the Registered Office of the Bank on all working days from 11:00 a.m. IST to 1:00 p.m. IST upto June 12, 2017.

For and on behalf of the Board of Directors
