Our ESG Approach

Focused on delivering ESG solutions that meet our clients' evolving needs

We believe an integrated approach to ESG investing can help increase portfolio diversification and maximize the incorporation of both ESG quality and alpha-related inputs.


Key Tenets to Our ESG Approach





ESG Guiding Principles

1. Our primary mission is to deliver superior, long-term, risk-adjusted returns for our clients.

2. We focus on material ESG issues which can affect the performance of individual securities to varying degrees over time.

3. We seek to integrate the analysis of potential risks and opportunities associated with ESG issues within our fundamental research process and we strive to mitigate related downside risks or capture upside potential as necessary, without compromising our fiduciary duty to act in the best interest of our clients.

4. In addition to conducting our business with the highest ethical standards and complying with all applicable laws and regulations, our ESG approach is regularly reviewed against industry investment stewardship and governance standards, and ESG methodologies to ensure alignment with our processes.

Impact Through Ownership Model

With responsible investing firmly rooted in our DNA, American Century Investments' focus on ESG factors is integral to our corporate citizenship and business model. Our ownership structure is unique in the asset management space as it enables our clients to directly support lifesaving research and contribute to the global fight against cancer.

In 1994, American Century Investments' founder, James E. Stowers Jr., and his wife Virginia—inspired by their personal experiences with cancer and a desire to use their wealth to help humanity—dedicated the vast majority of their net worth to create the Stowers Institute for Medical Research (SIMR) . SIMR is a private biomedical research institution focused on researching genetic-based diseases, including cancer. Through this distinctive ownership structure, whereby the institute is a controlling owner of American Century Investments, we have been distributing dividends to the institute since 2000. Those payments have totalled $1.5 billion.

ESG Oversight and Management

Oversight and accountability for American Century Investments' ESG-investing activities primarily fall under the responsibility of the Office of the Chief Investment Officer (CIO). The execution of our ESG policy and management of our ESG-investing platform falls under the purview of our Head of ESG and Investment Stewardship.

American Century Investments' multi-layered ESG framework combines both macro and sector inputs with a focus on financial materiality. The framework is aligned with our fundamental analysis process, and can be applied to various investments strategies in the equity and fixed income space.

Identify ESG Issues Affecting Sectors and Companies

Leverage third-party research and in-house macro assessments from ESG and Investment Stewardship team.

Identify ESG issues that could potentially affect long-term, market-specific dynamics and regulatory developments.


Determine ESG Risk Exposures at Sector Level

ESG and Investment Stewardship team partners with in-house sector analysts to isolate issues that could potentially alter sector-specific competitive forces.




Assess ESG Materiality at Issuer Level

Level of materiality depends on company's management practices to mitigate risks.

Utilize a proprietary tool to measure and rank issuers' relative risk management performance against quantitative environmental and social indicators.

Use a complementary tool to assess relative performance on governance that applies to all sectors.

Our ESG integration process extends to our proxy voting practices.

American Century Investments' proxy voting policy and practices are guided by general fiduciary principles. We act prudently, solely in the interest of the beneficial owners of the accounts that we manage, and for the exclusive purpose of providing benefits to such persons. In short, we vote proxies in the manner that we believe will do the most to maximize shareholder value.

We subscribe to certain proxy voting services offered by Institutional Shareholder Services (ISS), which services include the ISS proxy voting platform and proxy research, including their Socially Responsible Investing (SRI) proxy research. In 2018, we created an ESG (environmental, social and governance) Proxy team which is comprised of senior legal and compliance professionals and our head of ESG and Investment Stewardship. For American Century Investments' entire equity complex, our ESG Proxy team reviews, on a weekly basis, each proposal affecting our positions. With various inputs, including the ISS SRI proxy recommendations, the ESG Proxy team assesses the financial materiality of the ESG issues underpinning the proposals and makes appropriate voting recommendations to portfolio managers.

With regard to disclosure, the firm's proxy voting policies are available on the firm's website. Please note, we are in the process of updating these policies to reflect the ESG Proxy team involvement.
