Truman Hunt, president and chief executive officer, said: “We generated sequential business improvement in the fourth quarter as we continued introducing our newest ageLOC products.”
The launch of ageLOC was particularly strong in Asia, especially in Japan and South Korea, with the company seeing a high level of follow-on purchases in the first quarter, it said.
"As we introduce our new products throughout the year, the key to our success will be our ability to generate growth in sales leaders and a corresponding increase in actives,” Hunt added.
