In addition to its DuPont manufacturing, the Belle site also performs toll manufacturing for Lucite International and has two tenant businesses, Praxair and Kureha.
A DuPont company spokeswoman said earlier this year that it would be too early to speculate about the potential impact a sale could have on the West Virginia plants until DuPont executives decide exactly what they will do with the performance chemicals unit.
Kullman did not go into detail Thursday about the specific options the company was still considering, though she told analysts the company hopes to make a decision in the coming months.
"We're looking at lot of different options," she said. "We are operating with a sense of urgency and we want to get this done as quickly as we can."
DuPont on Tuesday reported third-quarter net income of $285 million, or 30 cents per share, on revenue of $7.8 billion. Removing one-time tax and pension costs, earnings were 45 cents per share, up from 43 cents per share last year and topping the 41 cents Wall Street analysts were expecting, according to a FactSet poll.
The company said strong demand for agricultural products in Latin America offset weak pricing for the performance chemicals unit's key industrial pigment titanium dioxide, or TiO2, a whitening pigment used in a wide range of products, from paint to toothpaste.
While the performance chemicals unit saw volume increase 12 percent in the third quarter, that was not enough to offset the steep price declines for titanium dioxide, refrigerants and fluoropolymers, along with higher raw material inventory costs.
The unit's operating earnings fell 38 percent to $254 million. Third-quarter results also included a one-time pretax charge of $72 million related to DuPont's settlement of titanium dioxide antitrust litigation.
DuPont's agriculture unit continued to lead the company's performance, with volume up 10 percent and prices improving slightly.
DuPont shares rose 71 cents, or 1.2 percent Tuesday, to close at $60.17, near their 52-week high of $60.86.
