ROCHESTER, NY—  Xerox's share price rose by close to 10% earlier last week after it posted a marginal Q2 sales increase on last year and a big adjusted operating income jump, despite its pre-tax loss also climbing. Xerox's sales climbed by 0.4% to $1.754 billion. But it made a Q2 pre-tax loss of $89m, up from $5m a year ago. Xerox said this was driven by a net pre-tax charge of $132m related to the donation of its Palo Alto Research Center, offset by continued cost reduction actions, cost improvements. Xerox’s operating income, jumped to $107m, from $35m a year ago. This excludes the PARC donation. Xerox said these benefits were partially offset by currency, the cessation of Fuji royalty income, higher bad debt, and employee compensation expenses.
