(Reuters) - Chipmaker Intersil Corp
The company expects to incur charges of about $9 million in the second quarter due to the restructuring, it said in a regulatory filing on Wednesday.
Intersil employed 1,643 workers as of December 31, 2011.
The company said the restructuring plan includes trimming operating costs by about $40 million annually.
Intersil's revenue has declined for the last four quarters. Costs, however, have not fallen, hitting its operating margins.
The company posted a wider-than-expected loss for the first quarter, as operating margins shrank to a negative 1.4 percent from 10.5 percent the year ago.
The company earlier this month had expressed its intention to limit its focus to a few top markets and segments during presentations to analysts and investors.
Shares of the company closed at $10.52 on Wednesday on the Nasdaq.
