Net income for the three months ending April 1, 2012 was $815 compared to $220 for the three months ending April 3, 2011, an increase of 270 percent. This increase is due to improved gross margins, reduced general and administrative expenses, and reduced interest expense. Correspondingly, basic and fully diluted earnings per share increased to $0.07 per share for the three month period ending April 1, 2012 compared to $0.02 per share for the same period ending April 3, 2011.
