Global Investor 30 - now open for submissions!

The GI30 is Private Debt Investor’s list of the world’s largest investors based on the market value of their private debt investment portfolios. For the 2019 ranking, this is based on the value as of 31 March 2019. This is a ranking of investors only and not fund of funds or private debt funds.

This year’s ranking will be published in October 2019 as a special supplement of the Private Debt Investor magazine, and we are seeking your help to ensure the data featured in the publication is as accurate as possible.

The ranking is based on the market value of investors’ private debt investment portfolios. This market value is measured at a single point in time for all investors to provide an apples-to-apples comparison. For the 2019 ranking, this is 30 June 2019. This is a ranking of investors only and not fund of funds or private debt funds

To submit data for the PDI GI30, please email Tom Zimmermann:

The only information shown in the ranking is the investor name, headquarters location, AUM, and the market value of the investors’ private debt investment portfolio as of 30 June 2019.

– Private debt

The definition of private debt investment, for the purposes of this ranking, is: capital committed by investors to a dedicated programme of investing in the debt of private companies, or the non-bank debt financing of leveraged buyouts, infrastructure projects and real estate. This includes distressed debt, fund of private debt funds, royalty financing, senior debt, subordinated / mezzanine debt, unitranche, and venture debt.

Both investors with a defined allocation to private debt, as well as those which are active investors in PD funds but may not have a defined allocation, are considered for this ranking. Where the investments are made in what may be termed a “grey area”, we reserve the right to make the final judgment based on applicability according to our definition.

We understand that investors’ definition of private debt may not entirely mirror the definition given above. Hence, we will use discretion to determine the most appropriate figure for each investor profiled.

– Structures and strategies

Capital committed or invested through the following strategies should be included:

  • Funds (both open-ended and closed-ended)
  • Separately managed accounts
  • Commitments to private debt fund managers that happen to be publicly traded
  • Capital committed to co-investment vehicles
  • Direct investments

Investors with direct lending platforms themselves are also considered for this ranking. For consistency purposes, Private Debt Investor aims to separate private debt direct lending from investment commitments. Where this separation has not been made available, a clear indication of this will be made on the published ranking.

Expected commitments: we do not count pending or future commitments and investments or the uncommitted portion of an institution’s target allocation.

Hedge funds: We do not count hedge fund strategies as these primarily target liquid securities or trading strategies.

Opportunistic investments: as there is no hard capital allocation to an investment programme.

Private Debt Investor’s Research & Analytics team will seek to communicate directly by phone and email with investors to find out the market value of their private debt portfolio as described above. In the absence of primary data, the team will gather data from secondary sources and seek to validate the researched figure with the investors themselves before we publish the final list.
