Kenneth J. Martin, the soon-to-be former chief financial officer at Wyeth, is going out with a bang.

According to federal securities filings, Martin has recently sold $17.5 million worth of shares, or 315,036 shares, in the drug company. That ranks him among the top insider sellers in the latest Bloomberg list.

On Friday, Wyeth said Martin, 53, will leave the company at the end of June to "pursue personal interests."

He became chief financial officer in 2000, executive vice president in 2002, and vice chairman last year.

In recent years, Martin has been eclipsed in the No. 2 spot by pharmaceuticial division chief Bernard Poussot, based in Collegeville. Poussot was named chief operating officer in January of the company headquartered in Madison, N.J.

Martin's successor has not yet been named.
