Visa ( V) shares were falling nearly 1.9% in late-day trading, after the credit card network posted a big loss for its fourth fiscal quarter. The San Francisco-based firm recorded a loss of $356 million, or 45 cents a share, for the three months ending Sept. 30. In the year earlier quarter, before it went public, the company posted a pro forma loss of $1.6 billion, or 96 cents a share. The loss was based on $1.1 billion of litigation reserves the company had set aside as part of its initial public offering in March. The settlement pertains to an ongoing lawsuit between Visa, MasterCard ( MA) and Discover Financial Services ( DFS). Discover and American Express ( AXP), which had previously settled with Visa and MasterCard, alleged the two companies had conspired to keep them from entering the bank-issued credit card space. Discover said late Monday that a settlement had been reached. Visa will pay a majority of the $2.75 billion, while MasterCard will pay $856 million of the settlement. MasterCard said on Monday it plans to take a charge of $515.5 million as part of its third-quarter results. Excluding litigation reserves and restructuring charges, among other things, Visa beat analysts' estimates. The firm's net income for the final quarter of its fiscal year was $448 million, or 58 cents a share. Net operating revenue was $1.7 billion for the quarter fueled by "service fees, data processing fees and international transaction fees." Analysts had pegged Visa would make 56 cents a share on $1.68 billion of revenue, according to Thomson Reuters. Analysts' estimates generally exclude special items.
