Outsourced Chief Investment Officer

Outsourced Chief Investment Officer

Learn how your organization can benefit from an outsourced chief investment officer. 

What is an Outsourced Chief Investment Officer?

An outsourced chief investment officer (OCIO) is a resource for organizations that can take on accountability and fiduciary responsibility for an asset pool, including strategic investment decisions. An OCIO also aims to manage liquidity trading costs and protect against drawdowns. Given the increased complexity of institutional investment programs, an OCIO can help investors access the expertise and scale they need to get the most out of their portfolios.

What are the Potential Benefits of Partnering with an Outsourced CIO?

  • Enhanced Governance

    Our delegated investment solutions allow fiduciaries to focus on strategic issues with the biggest impact on outcomes, including asset mix, investment structure and risk management.

  • Time Savings

    Partnering with our team allows asset sponsors to focus more of their energy on their organizations by spending less time managing their investments.

  • Lower Costs

    Aggregating global delegated assets increases the collective buying power for investment and delivers potential cost savings to all delegated/OCIO clients.

  • Unbiased Advice and Implementation

    Our open architecture and transparent fee model allow us to implement solutions we believe are in the best interest of our clients. We also leverage the expertise of investment managers who are buy-rated by Aon and ensure independence throughout our process.

  • Faster Execution

    Our ability to use discretion allows us to act quickly on asset allocation or investment manager changes. Clients don't need to worry about missing out on opportunistic investments or decision-making delays impacting investment performance.

  • Seek Better Outcomes

    Delegated investment solutions provide easier access to asset classes (including alternatives) and preferred investment strategies, potentially improving risk-adjusted returns through increased diversification and custom risk management strategies.*

What Should I Look for in an OCIO?

  • Scale and Infrastructure

    Does the OCIO have the scale and infrastructure to support multiple competencies and investment specialties?

  • Access to Asset Classes

    Can the OCIO access all asset classes and allocate assets across a range of risks?

  • Transparent Pricing Process

    How transparent is the OCIO's pricing process?

  • History of Generating Returns

    Does the OCIO have a history of generating returns and meeting client expectations?

*Diversification does not ensure a profit nor does it protect against loss of principal. Diversification among investment options and asset classes may help to reduce overall volatility. There is no guarantee that results or savings will be achieved if you should select Aon to provide services to you.
