NEW YORK, Feb 4 (Reuters) - Visa Inc, the world's largest credit-card network, said on Monday there is a 95 percent chance it will complete its initial public offering by Oct. 10, according to a quarterly filing.

The probability estimation was part of a calculation used to value a class of Visa shares.

The company in November filed to raise up to $10 billion with the offering, potentially making it the second largest U.S. IPO after 2000's $10.6 billion offering by AT&T Wireless. It has not disclosed the number of shares it will offer, or a price range for the share sale.

Visa also said on Monday that it posted net income for the quarter ended Dec. 31 of $424 million, up from $205 million in the same quarter the prior year.

Operating revenue rose to $1.49 billion compared with $845 million in the year-ago quarter, according to the filing.

Visa underwent a restructuring last October that combined Visa U.S., international and Canadian operations. Another affiliate, Visa Europe, will remain a membership organization and could a minority stake in Visa Inc.

Within weeks of the restructuring, Visa had filed with the U.S. Securities and Exchange Commission to sell its shares to the public. It plans to list its shares on the New York Stock Exchange under the symbol "V." (V.N)
