Reduced margins were primarily due to an approximately $7.0 million one-time charge for expiring production materials, and changes in product mix between the periods presented . The expiring production materials were purchased on behalf of the company by the OSATs in anticipation of a supply constraint and are no longer expected to be used.
Higher margins resulted primarily from the non-recurrence of an approximately $7.0 million one-time charge for expiring production materials in the prior year. Gross margin also benefitted from changes in product mix between the periods, partially offset by higher stock-based compensation associated with market and performance-based awards in the current year.
