Figure 4 provides summary measurement data for the environmental assistance and responsiveness categories for the past 5 years. These results are measured relative to Ciba's best competitor. The overall environmental performance ratings by our customers for 1989–1990 indicate that a little more than 20 percent of Ciba's customers perceived the company to be clearly #1, 10 percent perceived Ciba to be clearly not #1, and the balance (slightly fewer than 70 percent) perceived Ciba to be tied for #1.

These environmental performance numbers indicate that by 1993, more than 90 percent of the company's customers perceived Ciba-TPD to be #1 or tied for #1 with the company's best competitor, and major gains were made in comparison to best competitor since 1989–1990, as evidenced by the doubling of the company's clearly #1 ratings.
