Outlook, commentary and risks
Management forecast fiscal 2016 Q1 revenue of $157–$162 million and diluted loss per share of $0.08–$0.02. It expected R&D and SG&A expenses to increase in absolute dollars in Q1, and fiscal 2016 capital expenditures of approximately $14–$16 million. No full-year fiscal 2016 guidance is stated in the supplied filing text.
Fiscal 2015 income tax expense was $0.7 million, with a 2.2% effective tax rate. An unusual tax-accounting item was a $29.6 million tax benefit recorded following the Altera Tax Court decision, partly offset by a $27.5 million deferred tax liability associated with expected repatriation of certain foreign earnings. The tax outcome remains subject to appeal risk.
Key risks include semiconductor cyclicality and pricing pressure; dependence on distributors and third-party foundries, assembly and test providers concentrated in Asia; customer purchase-order cancellations and forecast-related inventory exposure; product qualification and adoption uncertainty; customer and product concentration; and acquisition integration and execution. The company had $8.0 million par value of auction-rate securities with failed auctions, carried at $7.1 million, whose principal may remain inaccessible until redemption, resale or maturity. Cresta Technology patent litigation remained active, including appeals; the company said the outcome and any financial impact could not be predicted. No material liability had been accrued for related customer indemnification.
