Net income for the year was $4.7 million, or 7.3% of net sales. Pro forma net income for the year ended December 31, 1996, was $3.8 million, or 7.0% of sales, excluding a non-recurring compensation charge of $1.4 million. Basic and diluted earnings per share for 1997 were $0.75 and $0.73, respectively. Fourth quarter net sales for the period ended December 31, 1997, were $17.0 million, representing a 27.6% increase compared to net sales of $13.3 million for the same period in 1996. Net income was $1.3 million, or 7.4% of net sales for the fourth quarter of 1997, compared to $0.6 million pro forma net income, or 4.6% of net sales for the fourth quarter of 1996. The Company's Board of Directors declared a first quarter dividend of $0.04 per share of its common stock, an increase from $0.035 per share in prior quarters. The dividend is payable on April 15, 1998, to shareholders of record as of March 31, 1998. "We are pleased that our production rates continued to increase in the fourth quarter, reflecting the successful completion of our 1997 capacity expansion programs," said Sun Hydraulics President Clyde Nixon. "Both the mobile and industrial markets showed strength throughout the year and our orders were up in all major market areas." "Our sales volume was up significantly for the year, despite our low shipment rates in the first six months," Nixon said. "Shipments for the last six months of 1997 were up 27.4% compared to the last half of 1996, and we expect to accelerate production rates in 1998. Although we successfully increased our shipments, expediting costs associated with meeting increased market demand, and start-up costs related to our capacity expansion programs impacted gross profit for the year." Sun Hydraulics is a leading designer and manufacturer of high performance screw-in hydraulic cartridge valves and manifolds for global industrial and mobile markets.
