The company had a loss of $16 million, or 61 cents a share, compared with earnings of $11.6 million, or 22 cents a share, in the same period a year ago. Revenue totaled $342.7 million, down from $386.3 million last year. Tom Duff, Wellman's chairman and chief executive, said in a statement that the company's first-quarter sales and earnings were hurt "by the surge in PET resin and polyester staple fiber imports that were caused by the increased raw-material cost advantage Asian polyester producers enjoyed compared to domestic producers during the latter part of 2005, primarily as a result of the Gulf Coast hurricanes." Shares of Wellman sank $1.42, or 20.6%, to $5.48. Monaco Coach ( MNC) took the high road after the Coburg, Ore., recreational-vehicle maker surged by Wall Street's first-quarter estimates.
