ONEOK engages in a comprehensive enterprise risk-management (ERM) process annually to identify and manage risk. Our ERM assessment is designed to facilitate a mutual understanding between our company’s board and management regarding the effectiveness of risk-management practices and capabilities, risk exposure and guidance on when to elevate certain key risks for discussion at the board level.

The program, overseen by our chief financial officer, is a key part of our annual strategic-planning process and is designed to identify, assess, monitor and manage risks that could affect our ability to fulfill business objectives or execute our corporate strategy.

ONEOK’s process involves identifying and assessing a broad range of risks and developing plans to mitigate them. These risks generally relate to the strategic, operational, environmental, financial, regulatory compliance and human resources aspects of our business. The board receives periodic updates on specific key risks throughout the year.

For more detailed information on ONEOK’s risk-management philosophy, see the 2020 Proxy Statement.


ONEOK’s Environmental, Safety and Health (ESH) Leadership Committee provides vision, leadership, direction and oversight for all ESH programs, processes and management systems. The committee is composed of senior management and subject-matter experts representing key areas of the company. An operations subcommittee co-chaired by ONEOK’s vice president of natural gas liquids operations and vice president of natural gas operations focuses on process safety oversight and opportunities.

The ESH Leadership Committee has recently driven action that, among other things, includes implementing the use of severity ratings in certain ONEOK ESH metrics in order to better understand trends and drive meaningful improvements.

The ESH Leadership Committee routinely provides updates to the board of directors through monthly board reports, and three of the committee members report directly to ONEOK’s chief executive officer, who is also a board member.

ONEOK formed an ESG Council in early 2019 as part of our corporate goal to continuously improve ESG performance and provide meaningful disclosures. The council, which ultimately reports to the ESH Leadership Committee, provides ONEOK with sustainability-focused vision, direction and oversight. Members include leaders from various departments across the company including Operations, Human Resources, Legal, Commercial, Corporate ESH, Government Affairs, SEC Reporting, Investor Relations and Communications.

Enhanced corporate disclosure milestones since the council’s launch include posting an ESG Performance Data Table with metrics on a growing number of items to our website and adopting the use of the Sustainability Accounting Standards Board (SASB) standards for reporting financially material sustainability information.

ONEOK’s approach to tax prioritizes compliance and risk mitigation. Our overarching tax strategy, including the consideration of tax policy, standards and principles, is overseen by our chief financial officer and is embedded within our company’s business segments and financial planning function. Additionally, members of the ONEOK Board of Directors Audit Committee review tax planning efforts and taxing authority developments.

We engage with multiple tax groups and taxing authorities to monitor legislation and ensure compliance. Our corporate tax activity is based within the U.S. and adheres to applicable laws at the local, state and federal levels.



ONEOK is committed to operating in an ethical manner and in full compliance with all applicable laws and regulations. Learn more about our ethics and compliance policies at oneok.com/about-us/ethics-compliance, including:

  • Code of Business Conduct and Ethics.
  • Non-retaliation Policy.
  • Whistleblower Policy.
  • Anti-corruption Policy.
  • Human Exploitation Policy.

The ONEOK Hotline provides for the submission of complaints or concerns regarding improper or unethical business behavior, questionable accounting or auditing matters or other matters arising under the ONEOK Code of Business Conduct and Ethics. The Non-retaliation Policy within the Code and the ONEOK Whistleblower Policy prohibit any form of retaliation against employees for raising a concern honestly and in good faith, or truthfully participating in a company investigation. Those using the hotline have the option to report anonymously. All reports, including those of retaliation, are investigated.


The ONEOK Anti-corruption Policy reinforces our commitment to conducting business in an ethical manner and in full compliance with applicable U.S. and foreign laws. Effective training on the policy is one of the many ways that ONEOK manages corruption risks and potential fraud.

All ONEOK board members complete annual corporate compliance training that covers our Anti-corruption Policy, Code of Business Conduct and Ethics, Securities and Insider Trading Policy, Statement of Policy Regarding Conflict of Interest and Antitrust Guidelines.

Employees directly impacted by the Anti-corruption Policy must acknowledge the policy and complete in-person training every other year. This group is made up of those whose responsibilities may involve international business dealings, including those working in accounting, audit, legal, treasury, finance and commercial roles. During 2018, a total of 106 employees participated in the in-person anti-corruption training. ONEOK’s 2020 training is being conducted online due to precautions regarding COVID-19, with a total of 188 employees enrolled.


Human exploitation traps millions of people, including children, in horrific situations around the world, including here in the U.S. Individuals who engage in human exploitation use violence, threats, deception, debt bondage and other manipulative tactics for the purpose of exploiting people, sexually and otherwise, for profit. ONEOK is committed to conducting business in an environment free from human exploitation of any kind and has adopted the ONEOK Human Exploitation Policy to reinforce our commitment.

We expect our employees, suppliers and others with whom we do business, to respect the human rights of all people and engage in ethical labor practices that are free of child labor, forced labor and other forms of exploitation.

To strengthen employee understanding and awareness around human rights and exploitation and to help clarify ONEOK’s expectations for identification and reporting of potential instances, we released a training video to all employees in April 2020. In addition to the training video, policy reminders and information are posted to our website, employee intranet and at common work areas across our operations.


Sustainable supply chain management is a priority for ONEOK, with the goal of continuous improvement and risk mitigation. We engage with suppliers annually to communicate expectations and highlight our commitment to sustainability, safety and ethical behaviors. ONEOK’s 2020 supplier expectations letter covered traditional topics (our Code of Business Conduct and Ethics, conflicts of interest and anti-harassment) and included new topics (environmental, safety and health, and human rights). In 2020, we also asked our Tier 1 suppliers to acknowledge receipt, review and understanding of our supplier expectations and received 100% acknowledgement. The Tier 1 category includes service and materials suppliers that make up the top two-thirds of annual expenditures and have been identified as suppliers that will continue to provide for ONEOK in the following calendar year.
