We expect gross margin to continue to vary from period-to-period due to a variety of factors such as sales volume, product mix and currency impacts. Operating expenses were $29.2 million versus $27.7 million in the year ago period. The increase was due primarily to higher sales and marketing and G&A costs, partly offset by lower R&D costs. Operating income was $10.9 million, representing 14.7% operating margin versus an operating loss of $7.9 million in the year ago period. We recorded a realized gain of $4 million from the sale of a portion of ACM Shanghai shares of SMIC for the quarter. Recall that the realized gains are included in non-GAAP earnings. Net income tax expense was $2.9 million compared to an income tax benefit of $4 million in the year ago period.
