text: Operating revenues were $62.8 million in 2003, compared with $59.5 million in 2002 and $57.6 million in 2001. These revenue increases are generally 
  attributable to higher sales volumes. The 5 percent revenue increase in 2003 over the prior year is primarily attributable to an 8 percent increase in the 
  revenues of the Company’s ophthalmic products, an 8 percent increase in the revenues of the Company’s cardiovascular products, a 3 percent increase in 
  the Company’s fluid delivery products and a 2 percent increase in the Company’s other medical and non-medical products and services. The 3 percent 
  revenue increase in 2002 over the prior year is primarily attributable to an 8 percent increase in the revenues of the Company’s cardiovascular products, 
  a 4 percent increase in the Company’s fluid delivery products and a 4 percent increase in the Company’s other medical and non-medical products and 
  services. 
  
  The Company’s cost of goods sold was $40.6 million in 2003, compared with $39.2 million in 2002 and $35.8 million in 2001. The increase in cost of 
  goods sold for 2003 over 2002 was primarily related to the increase in revenues discussed above and increased insurance costs partially offset by an 
  improvement in manufacturing variances resulting from increased production volumes. The increase in cost of goods sold for 2002 over 2001 was 
  primarily related to a shift in product mix, which resulted in lower gross margins, and the increase in revenues discussed above.
