HKUST’s Investment Surplus and ESG Investing: How the Reserves “Make Money” Under the Annual Report Lens

In a nutshell: The Hong Kong University of Science and Technology (HKUST) recorded a consolidated surplus of HK$1.162 billion for 2023/24^※, of which interest and net investment income contributed HK$1.089 billion^※; strip out the investment return and the underlying surplus is only around HK$73 million^※. This reveals the decisive role investment income plays in the annual bottom line. Since 2018 the University has practised ESG-aligned responsible investing, with over 75% of funds managed by UN PRI signatories; the Alumni Endowment Fund (AEF) operates on a principal-in-perpetuity basis, providing ongoing support to students.

# Why did the 2023/24 surplus reach HK$1.162 billion?

In the 2023/24 financial year (ending 30 June 2024)^※, HKUST reported total consolidated income of HK$7,517 million^※ and total consolidated expenditure of HK$6,344 million^※, yielding a post-tax surplus of HK$1.162 billion^※ (2022/23: HK$1.159 billion). The Annual Report explains that the 2023/24 surplus was driven mainly by significant investment gains, as markets anticipated interest-rate cuts by major central banks and improvements in corporate earnings outlooks linked to advances in artificial-intelligence technology^※.

Interest and net investment income for the year came to HK$1.089 billion^※, up from HK$807 million in 2022/23^※—an increase of about 35%. This single income line accounted for the overwhelming bulk of the consolidated surplus of HK$1.162 billion, making it the primary driver of the year’s positive bottom line.

# What is HKUST’s “underlying surplus” once investment returns are excluded?

The Annual Report distinguishes between the consolidated surplus and the underlying surplus—a measure that strips out investment returns to show the financial strength of the University’s recurrent operations. For 2023/24, excluding the effect of investment returns, the underlying surplus was roughly HK$73 million; in 2022/23 it stood at HK$352 million^※.

The figures are set out below:

The 2021/22 comparison is especially instructive: the underlying surplus that year was a positive HK$439 million, yet harsh investment-market conditions turned the consolidated result into a loss of HK$230 million. These figures confirm a key dynamic within the Annual Report framework—an upswing or downswing in investment markets can almost single-handedly decide whether HKUST’s annual accounts show a “profit” or a “loss”, while the recurrent operations, with that factor removed, remain relatively steady and in surplus.

# Where do HKUST’s investment earnings come from?

HKUST divides its reserves into UGC Reserves and non-UGC Reserves^※, both of which are invested. As at 30 June 2024, UGC Reserves stood at HK$4.629 billion and non-UGC Reserves at HK$9.998 billion, giving a combined total of over HK$14.6 billion^※.

Investment of the reserves is overseen by the Finance Committee of the HKUST Council^※. The portfolio consists mainly of public equities and public fixed-income instruments—the “in-scope assets” that are the focus of the ESG policy discussed below. Non-UGC Reserves are more than twice the size of UGC Reserves, meaning a very large proportion of HKUST’s investable assets comes from self-generated accumulations outside the government-funding system (donations, surpluses from self-financed programmes, and reinvested returns).

# When did HKUST begin ESG responsible investment? What is the policy framework?

HKUST has practised ESG (Environmental, Social and Governance) investing since 2018^※. In October 2022 the Council formally approved an ESG Investment Policy, making the University the first local institution to adopt such a policy^※; on 21 December that year HKUST publicly announced the policy, committing itself as the first university in Hong Kong to pledge the elimination of fossil-fuel investments^※.

The policy’s key features:

# What are the UN Principles for Responsible Investment (UN PRI), and how does HKUST engage with them?

The UN Principles for Responsible Investment (UN PRI) is the world’s largest network of responsible investors, requiring signatories to systematically incorporate ESG factors into investment analysis and decision-making, and to engage actively through proxy voting and disclosure. HKUST is not itself a direct signatory; instead, it implements the PRI principles by entrusting over 75% of its assets to fund-management firms that are UN PRI signatories^※. External investment managers must demonstrate to the University how they integrate climate risk into portfolio management and exercise proxy-voting rights.

In effect, HKUST does not manage its equity portfolio directly; it selects external managers with ESG-credentialed mandates, embedding its sustainability objectives at the contractual level—a model of “outsourced compliance” widely used by large institutional investors. The 2023/24 Annual Report^※ further notes that the fossil-fuel exposure covered by the policy is already 75% lower than the benchmark, and exposure to tobacco and controversial-weapons industries is close to zero.

# How does the Alumni Endowment Fund (AEF)’s principal-in-perpetuity mechanism work?

The Alumni Endowment Fund (AEF) was established in 2012^※ as HKUST’s first endowment fund with alumni as the primary donors^※. Its core financial structure is that the principal is held in perpetuity and only investment income is spent^※—a principal-in-perpetuity model consistent with the standard practice of major university endowments worldwide, ensuring the fund serves successive generations of students without eroding its capital through lump-sum withdrawals.

The AEF’s investment activities are likewise supervised by the Finance Committee of the Council; the Vice-Chancellor and President (together with vice-presidents) decide how the income is applied in line with the University’s strategic needs^※. Proceeds support four broad areas: talent and passion development, civic engagement and community service, financial aid and emergency support, and heritage initiatives and sustainability. Specific programmes include the AEF Student Entrepreneurship Fund, exchange scholarships and bursaries, sports scholarships, and the Student Emergency Fund^※, with the number of student beneficiaries growing steadily over the years.

From a financial-reporting perspective, the AEF is pooled with the University’s overall reserves and managed under the same investment umbrella; its total size and annual rate of return are not separately disclosed. Its surplus falls within the “Donations segment” in the Annual Report’s segmental results, and in 2023/24 the Donations segment recorded a surplus of HK$232 million^※, up from the previous year, mainly driven by improved investment returns.

# What does the volatility of investment income imply for the University’s finances?

The data above sketch a structural picture: HKUST’s reserve pool of about HK$14.6 billion is managed by external fund managers under the ESG policy framework, generating significant but variable investment income year by year. In a favourable market cycle (as in 2022/23 and 2023/24) this income can reach HK$800 million to HK$1.1 billion, greatly amplifying the headline surplus; in a down cycle (as in 2021/22) it can flip the consolidated result from surplus to deficit even while the recurrent operations remain in healthy positive territory.

Another structural point worth noting: non-UGC Reserves (HK$9.998 billion) are more than double the UGC Reserves (HK$4.629 billion). The larger the investable asset base, the larger the absolute swing in investment income; as the reserve pool continues to grow, this “investment-amplification effect” on the bottom line will become even more pronounced.

The Annual Report does not separately disclose the return impact of the ESG policy’s implementation, nor does it compare benchmark performance before and after ESG screening—a limitation of the current public data. Readers wishing to assess the ESG factor’s contribution to returns in greater depth would need to consult the specialised reports the University submits to external rating agencies.
