Electronic Access to Annual Meeting Materials

Onyx has implemented an electronic method for delivering annual meeting materials. Electronic access is quick, easy and convenient, while also being eco-friendly and cost effective compared to printed materials. While we will be switching to electronic delivery next year, we will be mailing printed materials in addition to providing online access during this transition year.
