Exhibit 99.4

Visa Inc. Completes Acquisition of CyberSource Corporation

On July 21, 2010, Visa Inc. (NYSE: V) completed the acquisition of CyberSource Corporation at a price of $26.00 per share, or a total of approximately $2.0 billion, to be paid with cash on hand.

CyberSource is an established industry leader in eCommerce payments and plays a role in processing approximately 25 percent of all eCommerce dollars transacted in the United States. Founded in 1994, CyberSource was one of the world’s first payment gateways, connecting online merchants to payment networks, including Visa. Today, CyberSource offers a full-service payment management platform for eCommerce merchants, combining global payment connectivity and processing with fraud management and secure payment hosting. These capabilities help merchants increase revenue through global growth while minimizing monetary loss through fraud and provide them with fast and efficient connectivity to payment networks, including Visa. Services are provided through two solution brands, CyberSource (large business) and Authorize.Net (small business).

The acquisition of CyberSource is an important step in Visa’s commitment to deliver an enhanced value proposition to merchants, financial institutions and consumers. The acquisition will result in a compelling combination whose assets and expertise are expected to support long-term growth by:

For online transactions, CyberSource’s technology performs payment routing and is similar to the card swipe machine found in the physical retail world. CyberSource manages the routing of transactions for online merchants, offers automated fraud management solutions, secures payment data storage services and provides a safe and secure connection to a multitude of payment networks, including Visa.

Visa does not issue cards, extend credit or set rates and fees for consumers. It is a global payments technology company that connects consumers, businesses, financial institutions and governments. Visa provides transaction-based services to our financial institution and merchant customers through VisaNet, our secure, centralized and global processing platform.

The company serves more than 300,000 merchants through its CyberSource and Authorize.Net branded solutions. CyberSource clients include medium to large businesses such as British Airways, Gucci Group and Google, while its Authorize.Net solutions serve small businesses with $3 million or less in annual online sales.

There will be no disruption to service. CyberSource will continue to provide its industry-leading electronic payment, risk management, and payment security solutions to online merchants large and small. Services will not be restricted to Visa payment products. CyberSource will be able to utilize Visa’s financial institution relationships and global presence to drive international expansion of CyberSource’s products and services. Customers will ultimately benefit from a broader portfolio of products and services that a combined CyberSource/Visa entity can offer.

Visa recognizes that part of CyberSource’s success is driven by its strong sales channel with 4,700 resellers and affiliates, and the company has no plans to make substantive changes to CyberSource’s Authorize.Net solution, partner programs or operations.

The acquisition will accelerate Visa’s growth in the eCommerce category, thereby increasing the usage of Visa debit, prepaid and credit products for online purchases. CyberSource’s enhanced fraud protection services ensure Visa’s consumers safer, more efficient transactions from online merchants. Given that the majority of CyberSource’s transactions are currently derived from the U.S., there is tremendous opportunity to expand its services globally, providing increased eCommerce revenue for Visa’s clients.

CyberSource will operate as a wholly-owned subsidiary of Visa Inc. CyberSource President and CEO Michael Walsh will continue to oversee CyberSource’s operations. CyberSource’s Executive Chairman and Founder, William McKiernan, will join Visa as an Executive Advisor to assist in the integration of the two businesses. Visa has no plans to make any substantive changes to CyberSource’s operations and intends to invest in CyberSource’s business and its employees.
