Revised: December 20, 2024 AVIENT CORPORATION Securities Trading Policy 1. Pre-arranged Trading Plans: An SEC rule, Rule 10b5-1(c), provides a defense from insider trading liability if trades occur pursuant to a pre-arranged “trading plan” that meets specified conditions. While trading plans can be established for a single trade or a series of trades, the Company prefers that your trading plan be established for a series of trades because Rule 10b5-1 places certain limitations on single trade plans.
