Notice to Canadian Shareholders

For Canadian shareholders of Automatic Data Processing, Inc. ("ADP") who received shares of CDK Global, Inc. ("CDK") in the spin-off that occurred on October 1, 2014, ADP received notice from the Canada Revenue Agency ("CRA") on January 15, 2015 that the spin-off distribution meets the requirements for the favorable tax treatment provided for in section 86.1 of the Income Tax Act (Canada). In general, where a Canadian shareholder of a foreign company receives a distribution of shares ("spin-off shares") from the company as a result of an eligible corporate reorganization ("spin-off'), section 86.1 of the Income Tax Act (Canada) may permit such a spin-off share distribution to occur on a rollover basis to the shareholder (e.g., taxation of any gains is deferred), provided the company provides certain information to the CRA and the shareholder complies with certain filing requirements specified in section 86.1. The CRA has published on its website the fact that the CDK spin-off has been approved for purposes of section 86.1 of the Income Tax Act. Therefore, Canadian shareholders are entitled to make the election specified under 86.1 in respect of the distribution. This election must be made with the shareholder's tax return for the taxation year in which the distribution occurred, and certain specific information must accompany the election. ADP is not providing any tax advice or guidance in respect of the application of section 86.1 or the filing of the election, and therefore Canadian shareholders should consult their own tax advisors in this regard.

Notice to Shareholders outside of the U.S. and Canada

In connection with the spin-off of CDK Global, Inc. ("CDK"), Automatic Data Processing, Inc. ("ADP") will not request tax assurances in foreign countries (other than Canada) that the distribution of CDK stock will be treated as a tax free distribution. Shareholders resident in countries other than the United States and Canada are encouraged to consult with a local country tax advisor to properly reflect the tax treatment of the distribution of CDK stock under foreign tax laws.

Canadian shareholders therefore are entitled to make the election specified under section 86.1 in respect of the distribution. The CRA has published on its website the fact that the Broadridge spin-off has been approved for purposes of section 86.1 of the Income Tax Act.

A Direct Registration System (DRS) allows investors to have securities registered in their names without the issuance of physical certificates. All newly issued shares of common stock of ADP will be registered electronically in an account maintained by EQ Shareowner Services, ADP’s transfer agent. Shares held in uncertificated bookentry form have the same rights and privileges as shares held in certificate form. Additional details regarding DRS may be found on the Securities and Exchange Commission’s website, http://www.sec.gov/investor/pubs/holdsec.htm.

Holding shares in book-entry form through DRS has many benefits to our stockholders, including:

• It helps reduce the risks and costs associated with storing share certificates and replacing lost or stolen certificates;
• It facilitates electronic transfer of stock to a new holder without a need to present a physical certificate;
• It makes possible moving shares electronically between your broker and EQ Shareowner Services;
• It gives you an opportunity to trade at any time and not risk “missing the market” because of delays associated with the handling of physical certificates; and
• It facilitates electronic processing of new issuances of stock associated with corporate actions (such as stock splits, reverse stock splits, mergers, etc.).

In addition, DRS brings significant advantages to ADP, such as:

• Immediate cost savings from elimination of printing, storage, insurance, and postage to mail certificates to stockholders;
• Reduction in administrative costs attributable to lost certificate processing and related shareholder inquiries and correspondence;
• Elimination of the opportunity for previously cancelled certificates to be fraudulently presented as valid instruments; and
• Potential savings in the time and expense associated with the research and processing of unexchanged certificates from any corporate actions.

Yes, you can send your existing share certificates toEQ Shareowner Services for registration in your DRS account. Your paper stock certificates were not automatically transferred into your DRS account. Please contact EQ Shareowner Services for information as to the formalities involved (see contact information at the bottom of this FAQ). A DRS Statement will be mailed to you upon receipt and processing of your certificates.

No, you cannot receive a share certificate for all or a portion of your shares held in book-entry form through DRS. The Board of Directors of ADP has resolved that effective July 1, 2008, ADP stop issuing new stock certificates and exclusively issue shares held in book-entry form through DRS. However, do not destroy any ADP stock certificates that you have. These are still valid and should be kept with your other certificates in a secure place. You will need to provide your stock certificates to EQ Shareowner Services when you transfer or sell any shares of ADP stock held in a certificated form.

In order to sell shares held in your DRS account, you will need to have a stock brokerage account, which you may open (if you don't already have one) at the broker of your choosing. If you wish to transfer your shares from your DRS account at EQ Shareowner Services to your brokerage account, whether or not you plan to sell your shares, contact your broker and provide him or her with your DRS account information (which will appear on the DRS Statement you will receive when you are issued new shares after July 1, 2008). Your broker will then electronically initiate the transfer of your book-entry shares based on your instructions.

You may transfer shares to a new owner by contacting the EQ Shareowner Services. Your instruction must include a Medallion Signature Guarantee. More detailed instructions are available at www.shareowneronline.com.

You will receive a DRS Statement following each transaction involving your shares held through DRS. You can also view your account at www.shareowneronline.com.

You will not be charged by ADP or EQ Shareowner Services for holding your shares of ADP common stock through DRS. Generally, switching to DRS should not result in any changes to the fees otherwise charged by your broker. However, brokers' policies may vary and we strongly recommend you contact your brokerage firm to determine whether a switch to DRS will result in any changes to their fees.

Your written consent and a Medallion Signature Guarantee are required by EQ Shareowner Services to transfer shares to any third party. If you choose to supply a broker with your DRS account information, your broker is responsible for obtaining your instructions and properly documenting any transfer or sale.
