Is your program suitable for a social impact bond?

A practical guide to help you self-assess your program’s appropriateness for a social impact bond (SIB).

The social impact bond (SIB) innovation is gathering pace around the world and here in Australia, but it is still very early in the development of this nascent market. Expectations are high – from investors and service providers alike – but implemented contracts are thin on the ground, and players are learning on the job when new SIBs are developed.

…the reality is that they are not a suitable funding instrument for all social programs.

With two state governments having taken their first steps in trialling SIBs, many organisations are actively considering whether a SIB would suit their program.

The allure of long term, large scale funding for a program is understandable, however there are many stars that need to align for a SIB to be viable. While SVA believes SIBs have the potential to provide significant benefits to governments, service providers and investors alike, the reality is that they are not a suitable funding instrument for all social programs.

This article provides key questions that organisations thinking of embarking on the SIB journey should consider, and viability ‘rules of thumb’ for those questions.

It should be noted that these ‘rules of thumb’ are just that: failure to meet a benchmark does not mean that a SIB is definitely not viable, but it does indicate where challenges would lie in developing a successful bond.

SVA has extensive expertise in the development and delivery of SIBs. In particular:

• We played a pivotal role in the development and launch of Australia’s first SIB, the Newpin Social Benefit Bond, which continues to produce strong social outcomes and financial returns. We have also been involved in the expansion of the Newpin program into Queensland, with the development of the Newpin Queensland Social Benefit Bond.
• In Adelaide, SVA has offered investors the opportunity to make a lasting difference to the lives of people experiencing homelessness through the Aspire Social Impact Bond, Australia’s first homelessness focused SIB.
• In NSW, we arranged the Resolve Social Benefit Bond, Australia’s first social impact investment aimed at improving mental health outcomes, and recently contracted a SIB aimed at supporting youth at risk of homelessness which is currently undergoing the property development phase, the Foyer51 Social Benefit Bond.
• We have also undertaken numerous social impact investment feasibility projects, and advised both State and Federal government in relation to the procurement of social impact investment transactions.

The big picture

Assessing a prospective SIB involves testing that it is viable across three core aspects:

• Our proposal will satisfy government considerations. Contracting to make outcome-based payments makes sense from a government perspective: there are potentially meaningful savings to be made, and a statistically sound, practical measure of those savings relative to a counterfactual^[1] is available.
• We will be able to deliver the outcomes required. A program exists or could exist that is highly likely to deliver the outcomes at a cost commensurate with the benefits.
• We will be able to attract investors. The program can be funded during the period of time before outcome payments start to flow, by attracting investors to a SIB^[2].

To a large extent these ‘layers’ of viability are listed in order of difficulty. The development of new SIBs is highly dependent upon governments being interested in developing outcome-based funding models, and being willing to adopt a proactive and pragmatic approach to supporting the evolution of these innovative instruments.

Each of these viability tests, and the key considerations that arise for each of them, are explored further below.

Would our proposal satisfy government considerations?

In some instances, governments may indicate the particular social problem they want to tackle through an outcomes-based contract, their preferred payment metrics^[3] and the value they attach to a positive outcome. However, clear government guidance on these key issues is not always available. A number of critical factors need to be assessed:

• The ‘care factor’
• Cashability
• Population identification
• Measurement
• Fair attribution

The ‘care factor’

Many intervention programs are framed around the social ‘symptom’ they seek to alleviate; in developing a SIB it is important to understand how these translate into government costs, and hence potential savings. In short, high cost problems get attention – the ‘care factor’ is high.

Figure: 1 How causes, ‘symptoms’ and government costs relate.

A complicating factor is that many social problems impact multiple layers of government, and multiple departments within a government. It is important to understand where the primary cost burden lies. Collaboration across governments and departments makes outcome contracts more complex, so ideally a lead department can be identified that would have significant financial upside from a successful intervention. Without a clear driver within government the development phase could be protracted – or unsuccessful.

Cashability

One of the key issues for government is how ‘cashable’ savings are. Fixed costs (for example running a prison or a hospital) may be difficult to reduce unless there is a substantial change in utilisation, whereas outlays directly related to an individual (for example, payments to foster carers) offer an immediate cash saving to government. Governments can use fully allocated costs as the basis for calculating savings, but in a constrained budgetary environment they are likely to focus on readily cashable savings.

Governments will also be cognisant of when potential savings will arise. There is a tension between the perceived efficiency of preventative programs and the long wait for associated benefits to accrue. Far-future savings are less certain to arise, and are likely to create a timing mismatch between outcome payments and reduced costs. Governments are thus less likely to take those potential savings into account in determining what they are prepared to pay for a successful outcome.

Population identification

The impacted population that generates government costs and could be targeted with an intervention program needs to be large and objectively determined. Without a clear definition of the targeted population it is difficult to determine a baseline or a counterfactual against which the SIB’s success can be measured. For example, finding and assessing people ‘at risk of losing a job’ is much more problematic than people ‘employed less than 10 hours per week’.

The impacted population also needs to be sufficiently large that it can support a statistically significant intervention group^[4] (and potentially a matched control group).

Measurement

For SIBs, measurement is everything.

Measuring outcomes serves as a proxy for the determination of the social impact of an intervention. It is important that a suitable outcome metric(s) can be identified that is a fair and practical basis for outcome payments and is acceptable to all stakeholders. Choosing the right outcome metrics is critical, and considerations will include:

• the strength of correlation to financial and social impact;
• the benefits of simplicity in contracting, calculating and communicating outcomes;
• the ability to source robust data for both program participants and a counterfactual;
• the need to wait (possibly for several years) for outcomes to emerge; and
• the potential for perverse incentives.

Generally, data for the determination of outcomes (and hence calculation of payments) will be sourced from government databases. For example, the payment metric may be the number of convictions recorded, or the number of hospital bed days.

It should be noted that the payment metrics sit within a broader measurement and evaluation framework that underpins the service provider’s performance management.

Fair attribution

To determine the extent to which a positive outcome can be attributed to an intervention program, results are compared with a ‘counterfactual’. The counterfactual is the estimation of what would have happened in the absence of the intervention. The counterfactual may be determined in a number of ways, including by reference to:

• the experience of a statistically matched control group drawn from the untreated population;
• historical outcomes for the target population; or
• the outcomes for a correlated population (eg in another state, or another age group).

There is likely to be a trade-off between accuracy and complexity in determining a fair counterfactual.

Will we be able to deliver the outcomes required?

Both the commissioning government and potential investors will require a high level of confidence that the proposed program will be able to generate sufficient social and financial outcomes (and hence outcome payments). Critical issues are:

• Program logic and evidence base
• Scale
• Organisational capacity
• Program cost

Program logic and evidence base

A tension exists between the potential for innovation in program design and the need for a credible evidence base to demonstrate that it will work. At this stage of the market’s development, evidence trumps innovation.

The ‘theory of change’ and detailed program design (activities and services, segmentation, scale, location, duration of support, referral/induction, staffing, systems and data management) all need to be clearly articulated in any SIB proposal. While most of these elements are no different to non-SIB programs, there is greater emphasis on some issues. For example, client referral and induction processes are critical in determining who exactly is on the program and when they entered it (for measurement purposes).

The estimate of the likely impact of the program is generally expressed as a percentage, for example, ‘government costs will be reduced by X%’. X is the ‘magic number’, and a strong rationale needs to be built for how it is determined, especially if X is large. While very few service providers can point to the published results of randomised control trials, strong evidence such as academic research or externally verified data from a current or commensurate program is desirable. For SIBs, ‘the plural of anecdote is not data’.

Scale

The program needs to be large enough that it generates statistically significant results, and sufficient government savings to justify the time and cost of developing a SIB.

Organisational capacity

Service providers need to be able to demonstrate that they have the capacity and capability to manage both the development and delivery of the SIB program.

The development phase requires time, data and sound analysis to work through the many complex issues that arise. The service provider needs to be able to cover the direct and indirect costs of participating in this process, including senior personnel with finance and service delivery expertise, as well as outlays including legal costs.

Once the contracts are in place, the service provider will need to be able to effectively manage the roll out and ongoing performance of the program, with a strong focus on delivering outcomes. The involvement of investors will likely see a greater emphasis on governance and performance reporting relative to non-SIB programs.

Program cost

The economic viability of a SIB hinges on the relationship between program costs and government savings. It is useful to express overall program costs on a per person basis to be able to compare them with the estimate of average per person government savings.

In estimating program costs, consideration needs to be given to any investment required to build delivery capability, and to the long term nature of outcome contracts.

Will we be able to attract investors?

As with any investment, SIB investors will consider a range of issues, including:

• Return (both social and financial)
• Risk
• Size of investment
• Liquidity and term

Return

To some extent, social return will be ‘in the eye of the beholder’, based on the investor’s perception of the social problem being addressed. A clear articulation of the nature and scale of the problem and an impact measurement framework (incorporating but broader than the payment metrics) are important.

The appropriate level of financial return will depend upon many factors, including the nature of prospective investors, the level of risk and the level of social return, and will sit somewhere on the spectrum between philanthropy and purely commercial terms.

Risk

Assessing the risks associated with a SIB investment poses some unusual challenges. Investors will potentially be exposed to risks such as a smaller than expected number of program participants, or a better than anticipated counterfactual outcome (making it harder to generate improvements) – in addition to the key risk of program efficacy – which may be difficult for them to analyse.

A key consideration for investors is the proportion of their capital that is at risk in a worst-case scenario (ie if the program does not generate outcomes any better than the counterfactual). Capital loss can be mitigated in a range of ways, including government risk sharing (achieved through structures such as minimum payments or part guarantees), a philanthropic or first loss tier, and early termination provisions for underperformance.

Risk sharing with the service provider is another key consideration. The higher the degree of ‘skin in the game’ for the service provider the greater the alignment of interests, providing investors with confidence that program design and management will be responsive to experience and emerging outcome data.

Size of investment

Broadly, the amount of capital that needs to be raised is equal to several years’ program costs plus the ‘overheads’ of establishing and running the SIB (in particular legal, intermediary and evaluation costs), although this figure is highly dependent upon the structure of outcome payments and any other funding sources (for example fixed government payments).

The smaller the SIB, the higher the overhead establishment costs as a proportion of the capital proceeds. Small SIBs are also unlikely to appeal to institutional investors, who prefer larger scale investments to justify their due diligence costs. Overall, the bigger the better from a cost effectiveness perspective.

Liquidity and term

SIBs are generally illiquid instruments, so investors will expect to ‘buy and hold’ until maturity. This makes the term of the bond an important consideration.

Conclusion

SIBs are an innovative and promising addition to the social services landscape, but they are not a silver bullet. Governments, service providers and investors need to work through a number of complex issues in determining whether a SIB proposal stacks up.

For any organisation considering whether a SIB would suit its program, it is worthwhile running the ruler over these key elements to assess the viability of the potential SIB. SVA has extensive expertise in the development and delivery of SIBs, and has developed ‘rules of thumb’ to help organisations conduct this high level assessment. If you believe you have a potentially viable proposal, intermediaries like SVA can help you develop and ‘stress test’ the details, and prepare for the next steps in the development process.
