Why Asset Owners Hire an OCIO: A Conversation with Aon’s Bryan Ward

Why Asset Owners Hire an OCIO

An OCIO can help design and implement investment strategies that align with the plan’s objectives, offer a diverse range of investment options, and ensure compliance with fiduciary responsibilities.

Key Takeaways
  1. OCIOs allow asset owners to delegate tasks to outside professionals.
  2. OCIOs can help implement complex strategies cost-effectively.
  3. Asset owners should consider if they have the time, expertise, and resources to manage their portfolio.

Q: Bryan, let’s start with the basics. What exactly is an OCIO, and why is this model gaining traction among asset owners?

Bryan Ward: At its core, an Outsourced Chief Investment Officer (OCIO) is a discretionary investment model. It allows asset owners — whether pension plans, endowments, foundations, or defined contribution plans — to hand over day-to- day investment decision-making to a dedicated team of professionals. This includes everything from manager selection and portfolio rebalancing to liquidity management, contracting with managers, and risk oversight. The asset owner still retains responsibility for setting the investment policy, including key things like the strategic asset allocation, while the OCIO implements that investment policy.

The model is gaining popularity because the investment landscape has become more complex. Regulatory changes, market volatility, and the proliferation of asset classes have made it harder for internal teams to keep up. An OCIO brings scale, strong governance, expertise, and agility to help organizations navigate this complexity. Further, because large OCIO’s have scale across many asset owners, they are often able to negotiate attractive fees with asset managers that make the all-in fee comparison for OCIO services very competitive.1

Q: You mentioned governance. Can you elaborate on how an OCIO improves governance for asset owners?

Bryan Ward: Absolutely. Many organizations struggle with governance — whether due to limited staff, infrequent investment committee meetings, or a lack of in-house expertise. An OCIO provides continuous oversight and decision-making, which helps reduce delays and missed opportunities.

We also assume a level of fiduciary responsibility, which can help protect investment committees from potential litigation. That’s a big deal, especially for organizations with complex portfolios or regulatory exposure. Our role is to act as an extension of the client’s team, bringing discipline, documentation, and accountability to the investment process.

I’ve mentioned this in the past, the decision by an asset-owner to engage an OCIO is first and foremost a governance decision. How best will the portfolio’s objectives be achieved? Managed internally or externally via an OCIO? Do not allow the limitations of the current governance model dictate the complexity of the portfolio strategy. Determine the optimal portfolio based on the needs and objectives of the organization, then determine the optimal governance model required to achieve them.

Q: Let’s talk about portfolio construction. How does an OCIO help asset owners build more diverse portfolios, particularly with alternative assets?

Bryan Ward: This is one of the most compelling reasons to hire an OCIO. Alternative assets — like private equity, private credit, hedge funds, real estate, and infrastructure — offer diversification and the potential for higher returns. But they’re also complex. They require specialized knowledge, operational infrastructure, and access to top-tier managers.

Most organizations don’t have the internal resources to evaluate, select, and monitor these investments effectively. That’s where we come in. At Aon, we have a global research platform and deep relationships with alternative asset managers. We can help clients build customized portfolios that include alternatives in a way that aligns with their risk tolerance, liquidity needs, and long-term goals. The specific type of alternative investments and size of the allocations varies a lot by client circumstance, especially the need for liquidity, so some clients focus only on the more liquid strategies while other incorporate the broader universe.

Q: Are you seeing increased demand for alternatives among your OCIO clients?

Bryan Ward: Definitely. According to research from the Chartered Alternative Investment Analyst Association, alternatives have grown from 6% of the global market in 20042 to 15% by the end of 20233, and we think it is poised to grow further. That growth is being driven by institutional investors who are looking for ways to enhance returns and reduce reliance on traditional equity and fixed income, especially today, as valuations in public equities appear stretched.

We’re helping clients tap into that opportunity. For example, we recently worked with asset owners to introduce diversified alternatives sleeves that included private credit and infrastructure, among other strategies. It may help them improve their expected returns while managing downside risk.

Q: What are some of the operational challenges asset owners face when trying to invest in alternatives on their own?

Bryan Ward: There are several. First, sourcing and vetting managers is time-consuming and requires deep due diligence. Second, the operational demands — like capital calls, performance reporting, and legal reviews — are significant. Third, many alternative strategies are illiquid, so you need to manage cash flows carefully.

An OCIO can handle all of that. We have dedicated teams for operational due diligence, legal contracting, fee negotiation, and performance analytics.4 We also help clients model liquidity and stress-test their portfolios. That’s a level of support that’s hard to replicate internally unless you’re a very large institution.

Q: How do you tailor OCIO solutions to different types of asset owners?

Bryan Ward: Every client is different. A university endowment has different goals and constraints than a corporate pension plan or a healthcare foundation. That’s why we start with a deep discovery process — understanding the client’s mission, liabilities, spending needs, risk tolerance, and governance structure.

From there, we build a customized investment strategy. That might include a dynamic glide path for a pension plan, or a mission-aligned responsible investing strategy for a foundation. We also offer different levels of delegation — from partial to full OCIO — depending on the client’s preferences.

Q: How can OCIOs be valuable for pension plans in their last mile before termination or during liability settlements?

Bryan Ward: OCIOs can be particularly valuable for pension plans in their final stages before termination or when settling liabilities through lift-outs or lump sum windows. These processes require precise timing, careful management of assets, and adherence to regulatory requirements. For example, whether they pay for annuities with asset-in-kind transfers or cash, there are important nuances in how the portfolio should be structured and adjusted in the period leading up to the transaction — plan sponsors need a partner experienced with these transactions to minimize the possibility of costly surprises.

An OCIO can provide the expertise and operational support needed to navigate these complexities. We help pension plans optimize their asset allocation, manage liquidity, and execute transactions efficiently. This helps to ensure that the plan can meet its obligations to beneficiaries while minimizing risks and costs.

Q: How can OCIOs be valuable for defined contribution plans?

Bryan Ward: Defined contribution plans may benefit significantly from the OCIO model. These plans often face challenges related to participant engagement, investment options, and regulatory compliance.

An OCIO can help design and implement investment strategies that align with the plan’s objectives, offer a diverse range of investment options, and ensure compliance with fiduciary responsibilities. An OCIO takes many of the operational responsibilities off the plan sponsor so it can focus on more strategic issues. Pooled Employer Plans (PEPs) have emerged as an attractive alternative to traditional defined contribution plans. PEPs use a Pooled Plan Provider (PPP) which acts as the named fiduciary and plan administrator, providing centralized management and oversight. The PPP is responsible for selecting and monitoring the PEP service providers, including the ERISA Section 3(38) investment manager — the OCIO — who has discretionary authority over the plan’s investments, helping to streamline operations and improve outcomes for participants.

Q: How can OCIOs help endowments and foundations?

Bryan Ward: Endowments and foundations have unique investment needs, often driven by their mission and long-term goals. An OCIO can help these organizations build diversified portfolios that include alternative assets, align investments with their mission, and manage risk effectively.5

We work closely with endowments and foundations to understand their specific objectives and constraints, and then design customized investment strategies that support their mission while optimizing returns. This tailored approach helps ensure that these organizations can continue to fund their important work for years to come.

Q: What should asset owners look for when selecting an OCIO partner?

Bryan Ward: Three things: alignment, transparency, and capability.

Alignment means the OCIO understands your goals and acts in your best interest. Transparency means clear fees, open communication, and no hidden agendas. Capability means the OCIO has the scale, expertise, and infrastructure to deliver results.

At Aon, we’ve built our OCIO platform on those principles. We offer tiered fee structures, separate our fees from those of the underlying investment managers, passing savings on manager fees back to clients, and we’re constantly investing in research and technology to stay ahead of the curve.

Q: Finally, what’s your advice to asset owners who are considering the OCIO model but haven’t made the leap yet?

Bryan Ward: Start by asking yourself: Do we have the time, expertise, and resources to manage our portfolio effectively in today’s environment? If the answer is no — or even “not sure” — then it’s worth exploring the OCIO model.

You don’t have to go all in right away. Many clients start with partial delegation or a pilot program. The key is to find a partner who can help you build a more resilient, diversified, and forward-looking investment strategy.
