Calix is an organization with strong values of responsibility and integrity. Our Code of Business Conduct and Ethics and our Supplier Code of Conduct state our expectations for conducting business with the highest standards of ethics. E-learning of our Code of Business Conduct and Ethics is mandatory for all our employees upon on-boarding and annually thereafter. Additional training is required of our employees as part of our internal management and leadership development programs, as relevant.

Calix is committed to an environment where open, honest communications are the expectations, not the exception. We want you to feel comfortable in approaching us in instances where you believe violations of policies or standards of ethics have occurred. Our Whistleblower Policy provides procedures for reporting accounting and/or audit related violations.

In situations where you prefer to place an anonymous report in confidence, you are encouraged to use our hotline or web report form hosted by a third party hotline provider, EthicsPoint, to submit reports relating to violations of the standard stated in our Code of Business Conduct and Ethics.

The information you provide through the hotline or web report form will be reported to us on a totally confidential and anonymous basis if you should choose. Calix is committed to fully investigating all reported violations.
