Already an investor? Access all fund information here

Congratulations to Ai CIO for their most recent survey* highlighting that lack of internal resources, improved risk management and a desire to capture opportunities more quickly as 3 key reasons why institutional investors continue to adopt governance models that increasingly include delegation. We are delighted to continue to lead the global market for full discretionary OCIO assets under management, for our Investment Solutions and OCIO services, to help clients address these critical issues.

* Submitted 9/30/20 data

* Source: Chief Investment Officer (, full discretionary OCIO Assets under Management (AUM) ranked by worldwide assets under advisement as of September 09, 2020 as reported by each firm to ai-cio. Mercer did not pay a fee to participate in this survey. This survey is not indicative of the adviser’s future performance. Mercer’s global AUM reached $380bn as of March 31, 2021. Please see Important Notices for important information about Assets under Management.

Many investors seek guidance on setting a strategy, manager research and allocation and the day-to-day operations of an investment program. We call these “investment solutions”. There are many names for investment solutions around the world, including OCIO, delegated solutions, fiduciary management, implemented consulting, but they all centre on the same thing - supporting institutional investors in an effort to meet their goals more efficiently. Implementing an investment solution can help you maintain control and feel confident knowing your investments are in professional expert hands.

Challenges investors are facing


How to integrate ESG into an overall strategy?

The shift to a zero-emission economy is high on the agenda for a great number of governments and organisations globally. Many have either made pledges for change, or put a plan in place to start. We believe it is critical for investors to assess and address their ability to transition and start investing in companies positioned to perform well in a renewable economy.

How to benefit from good investment governance?

In an increasingly unpredictable and volatile geopolitical age, resilience is key for investors. Resilience can be achieved through good governance and a diversified portfolio that has established operational structures with clearly defined tasks. Good governance can help prepare for market volatility.

How to enhance a portfolio with private markets?

Investors are looking for alternative sources aimed at diversifying risk and boosting returns. Private markets are widely used. These assets are generally less sensitive to short-term public market volatility and have the potential to earn a premium if held over a longer-term. They’re not always easy to access, but they’re definitely worth the consideration.

Investment Solutions could give you a Governance Advantage


“A governance advantage enables our clients to access timely information, respond quickly and make effective decisions. This helps them to manage risk and capture emerging opportunities. Good governance underpins everything we do as an investment partner.”

Mick Dempsey, Global Head of Investment Solutions & OCIO services.


Private markets: broad opportunities, enhanced diversification and higher yield

Private markets are becoming increasingly popular as investors shift parts of their portfolios away from publicly traded assets in order to diversify their risk and return drivers. The opportunities in private markets span many sectors and regions, each offering something different to investors. Yet they all share the qualities of being shielded from much public market volatility and having the potential to earn a premium by being held over the long term.

However, accessing managers that invest in private markets can be challenging for some investors – this is where Mercer can help. We have been investing in these markets for more than 25 years, establishing deep relationships with a wide universe of highly-rated managers. Our dedicated alternatives group of over 180 professionals across 20 global locations, work on $200bn of alternatives advisory mandates for clients - $21bn of assets being under direct implementation.2

Investment solutions mythbusters




OCIO, fiduciary management, delegated solutions and implemented consulting are all different

There are many names for this approach, which vary by region rather than varying by what they do. They all centre on the same thing: supporting institutional investors to meet their goals more efficiently. Each provider will have their own approach, but at Mercer we let you decide how you want to work with us. Call it what you like — we call it “Investment Solutions” — and make it work for you.


Investment outsourcing would make us give up control of our portfolio and investment decisions

We want to put you back in control and feel confident that your investments are working towards your goal. By lifting the burdens of implementation, monitoring and reporting, we aim to free up your time to focus on overall strategy and the challenges your organization may face. Assigning the day-to-day portfolio management decisions to our experienced team helps you to nimbly shield your assets from risks and capture emerging opportunities in the market.


Investment outsourcing  would cost us more than our current arrangement

Due to our size and market position, we are able to negotiate on fund manager and other provider fees, which often results in savings passed to the end investor. We believe investment solutions can help investors reach their goals more quickly, thereby cutting the time — and money — spent on the journey.


My portfolio is too simple or too complex to need an investment solution.

Investment solutions can help a wide range of investors take control of their portfolios and refocus on their objectives. Every investor is different, and they each have their own goals, objectives and challenges. We assist organisations of all sizes and complexities to feel confident that their bespoke investment strategy is being implemented, managed and monitored by specialists, who are aligned with their interests.


It’s a one-size-fits all option.

Investment solutions aim to do what you need them to do and not what you don’t. From bespoke investment strategy design to implementation and monitoring of managers, each client works with us in the way they choose. We are here to support investors in whichever way they need — and we can flex with you along your journey.

We can also implement their own strategy, using our institutional-standard operational platform to access a wide global range of managers and asset classes – at competitive fees.


Our dedicated sustainable investment team can also help our clients shape an ESG policy, according to their principles and beliefs, exploring risks and opportunities that could significantly impact their portfolio. We conduct rigorous oversight of portfolios to ensures managers are sticking to their claims on ESG to protect our clients from reputational damage connected to a sector or company.

Investment solutions for insurers

From large, global multi-line insurers to small regional specialists, we help many organisations enhance the oversight of their portfolios, while potentially reducing implementation costs and carefully managing risks. Our investment solutions framework is fundamentally a governance structure that has been designed to give our clients access to as much of our institutional investment capability as they need. It functions as a range of core building blocks that insurers choose and combine to create a precise, tailored package to suit their objectives and budget. Whether you need a complete end-to-end solution, informed regulatory reporting or just a trusted second opinion, we have what you need.



Why insurers should partner with us?

The starting point for any insurer’s investment strategy is to identify the outcomes that are essential to fulfil business objectives and will not change according to market conditions. This strategy must also be able to accommodate complex and changing regulations, without jeopardising the fulfilment of these objectives. Equally important is for insurers to stay in control of this strategy while ensuring efficient implementation and solid cost management.
