Below is a list of defined terms that are commonly used in the impact investing space.  I will periodically update them or add new ones, especially when cross-referencing them in my blog posts.  These definitions are based on my understanding, but borrow from publicly available information.  I have attempted to include hyperlinks to sources where appropriate.

Accredited Investor

An accredited investor is a type of sophisticated investor (see below). In the United States, according to the SEC, an accredited investor is anyone who earned income in excess of $200,000 (or $300,000 together with a spouse) in each of the prior two years, and reasonably expects the same for the current year, or has a net worth over $1 million, either alone or together with a spouse (excluding the value of the person’s primary residence). A company or private fund may not offer or sell securities unless the transaction has been registered with the SEC or an exemption from registration is available. Certain securities offerings that are exempt from registration may only be offered to, or purchased by, persons who are accredited investors. One principal purpose of the accredited investor concept is to identify persons who can bear the economic risk of investing in unregistered securities.

Community Development Finance Institutions (“CDFIs”)

CDFIs are mission-driven, private financial institutions that provide credit and other financial services to underserved markets and populations with a goal to make them more financially self-sustaining. They expand economic opportunity by providing credit for small businesses, micro-enterprises, affordable housing, charter schools and non-profit organizations. Their target markets include minority and women-owned businesses in low-to-moderate income communities that are not traditionally served by mainstream commercial banks. In the United Kingdom they are known as Responsible Finance Providers.

Donor Advised Funds (“DAFs”)

DAFs are charitable giving vehicles that allow donors to make an irrevocable charitable contribution in a specific tax year to realize an immediate tax benefit and then recommend charitable grants from the fund over time.  Donors can contribute to the fund as often as they like, placing funds into a donor-advised fund account where it can be invested and grow tax-free. At any time afterward, the donor can recommend grants to their preferred, qualified charities when convenient. Donors can contribute cash as well as other personal assets, including stock and real estate. This can create an additional tax advantage if the assets have appreciated in value as the donor can avoid paying capital gains taxes. DAFs also offer administrative convenience and cost savings for donors that would otherwise have to set up a foundation or trust. There are many specialized DAFs that offer impact investment options to donors as an alternative to mainstream investments. In this way donors can magnify the social impact of their DAFs by investing them in social impact ventures until they decide how to donate the money to charity. Since DAF assets have already crossed the philanthropic boundary, they will never go back to the donor, which means DAF capital can afford to be more risk-taking, and thus catalyze other more commercial investors into impact ventures.

Development Impact Bonds (“DIB”)

DIBs are a variation on Social Impact Bonds (see definition below) except that instead of a local government paying for realized outcomes, it is typically an aid agency or a philanthropic foundation that repays the investors.   Development impact bonds are also specific to projects in low and middle income countries, whereas Social Impact Bonds are used to finance social interventions in developed countries.   As an example, impact investors agree to provide up-front funding to an eye hospital in Africa to perform a predetermined number of cataract surgeries on low-income patients within a specific period of time.   The philanthropic organization then agrees to repay the investors’ principal and a predetermined rate of interest if, and only if, this number of surgeries is successfully performed by the eye hospital within this specific time period.  In this way, the philanthropic organization only pays for the specific development outcomes (the cataract surgeries) that have been realized, and the risk of not achieving this goal is born by the private impact investors who, in turn, receive a financial return over and above the cost of the surgeries (in addition to the “social” return on the financed intervention) in exchange for taking this performance risk.

Environmental, Social and Governance (“ESG”)

ESG criteria are non-financial factors that investors use to analyze and screen companies.  Environmental factors examine issues such as how energy efficient a company is or its level of CO2 emissions.  Social refers to factors such as a company’s labor practices, customer satisfaction levels or product safety issues.  Governance factors examine issues such as accounting transparency, board independence or whether there is a history of corrupt dealings.  There is no one set of ESG factors and they vary in importance across sectors.  Some investors are motivated to use ESG factors because of their values, while others are looking to analyze non-financial risks.

Green Bonds

Green bonds (also called “Climate Bonds”) are traditional fixed income securities that are issued in order to raise funds for a project that benefits the environment, such as the construction of a solar power plant or wind farm.  Issuers are both sovereign and non-sovereign.   The popularity of green bonds has grown substantially over the last several years and demand for green financing is expected to increase substantially as a result of the emission reduction targets in the Paris Climate Accord.  Critics of green bonds point out that there is no universal set of criteria to certify what a green bond is, which leaves some bonds vulnerable to “green washing” by issuers.   In response, the International Capital Markets Association has established a set of green bond principles to maintain the integrity of the market, and the Climate Bonds Initiative (a UK non-profit) offers green bond accreditation and certification.  Another important question is, does the issuer need to be green or just the project that is being financed by the bond?  If an oil and gas company issues a bond to retrofit its plant and equipment to reduce carbon emissions, is that a green bond?

Impact Investing

Impact Investments are investments made in social enterprises or investment funds that target social enterprises with the intention of generating positive social and/or environmental impact alongside a financial return.  The term “double bottom line” is also sometimes used to describe the same concept.  Some definitions include “measurable impact” to emphasize that social and environmental returns are often measured and reported to investors.  Depending on the strategic goals of the investor, such investments can be made in frontier, emerging or developed markets, and can target a range of financial returns from commercial (“market”) returns to concessional (“below-market”) returns.

Impact Reporting and Investing Standards

Also known by its acronym “IRIS”, this is a catalog of generally-accepted metrics developed by the Global Impact Investing Network (“GIIN”) used by impact investors and social enterprises to measure and report on their social, environmental and financial performance.  They were developed to enable “apples to apples” comparisons across different ventures.    If two companies are reporting “jobs created” or “greenhouse gas emissions avoided” and both are using the same IRIS definitions, then their performance relative to one another can be more objectively tracked.

An MRI is an investment made from the endowment of a tax-exempt foundation, which is intended to generate financial returns as well as further its charitable mission by achieving a positive social or environmental impact.  In the past, the investing side of a foundation (which generally focused on achieving profit-maximizing, risk-adjusted returns) occasionally came into conflict with its charitable giving side (e.g. a foundation promoting public health holding tobacco or coal mining stocks).  With MRIs, a foundation can allocate money to impact investments and still be considered by the IRS to be exercising “ordinary business care and prudence” even if the expected rate of return is less than what it might earn on an investment that is not mission-focused.  MRIs are related to, but distinct from “Program Related Investments” (see “PRI” below).

A PRI is a (typically) below-market rate investment made by a tax-exempt, charitable foundation as part of its annual giving requirement.  Charitable foundations are required to give away at least 5% of their assets annually in order to maintain their tax-exempt status.  Typically this is in the form of grants to non-profits, but PRIs allow foundations to make for-profit investments (loans, guaranties and equity investments) provided that the primary purpose of the investment is to further the charitable mission of the foundation, and not achieve financial gain.   The IRS allows PRIs to be treated as grants (counted toward annual giving requirement) provided the goal of the investment is not to generate market-rate returns.  Per IRS definitions, this means a purely profit-driven investor would be unlikely to invest on the same terms and conditions as the PRI.   Foundations such as Rockefeller and Skoll have used PRIs to make impact investments in social enterprises and other high impact ventures.  PRIs are related to, but distinct from “Mission Related Investments” (see “MRI” above).

Social Enterprise

A social enterprise is a type of business that provides basic goods and services to low-income populations in an affordable, sustainable and scalable manner.   They are typically for-profit, which provides a degree of market discipline and makes it easier to raise capital, but can sometimes be incorporated as non-profits.  Basic goods and services refer to things that are typically provided by public utilities in the developed world, such as electricity, sanitation or water, as well as other services like education, healthcare, finance and housing.  Social enterprises are often driven by a specific mission, and have business models that are designed with the intent of delivering a positive impact on society and/or the environment.  Often this intentionality is demonstrated and monitored by way of specific impact metrics. These characteristics distinguish social enterprises from purely profit-driven companies, which exclusively maximize shareholder profit.  This has given rise to new models of legal incorporation, such as benefit corporations, where the mission is embedded in the goals of the company to avoid the potential conflict between profit-maximization and achieving impact.  In this way, company directors are freer to make decisions without jeopardizing their fiduciary responsibility to shareholders.

Social Impact Bonds (“SIB”)

Social-impact bonds, (also known as “pay-for-success contracts”) are not really bonds or fixed income securities in the traditional sense, but are instead a new way to finance and implement social services.  Private impact investors pay up front for a social intervention that is preventative in nature and delivered by a third party (typically a non-profit) to a vulnerable population.  Local or state governments then promise to use savings from avoided costs to repay the private investors, but only if the intervention is successful, i.e. certain predetermined, measurable outcomes have been achieved.   Social impact bonds allow governments to pay only for specific results (hence the name “pay for success”) and brings in private investors, who have a financial incentive to monitor progress and are in a better position to hold the service provider accountable for achieving results.   As an example, private investors provide up-front funding for a preschool program for children who have tested as being at risk for needing special education services.  The local government pays back investors if, and only if, these at risk children benefit sufficiently from the preschool program, and the government achieves savings from the avoided special education program costs.   Predetermined rates of return are paid to investors based on how successful the preschool program is at preventing these children from requiring special education assistance.   Other SIBs have financed interventions to prevent re-incarceration and homelessness.  Similar structures are used in the developing world in which the outcome payor is an aid agency or philanthropic organization (see “Development Impact Bonds” above).

Socially Responsible Investing

Socially Responsible Investing or “SRI” is an investment style that is often referred to as “do no harm.”  It is an investment strategy that uses various screens or filters (such as ESG factors) to eliminate securities from an investment portfolio that are considered to be harmful to the environment (e.g. coal power) or to society (alcohol, tobacco, pornography, gambling).  This latter category is also sometimes referred to as “sin stocks” as they deal with sectors that are considered by some to be unethical or immoral.

Sophisticated Investor

In many countries, the financial market regulator or securities commission distinguishes between retail investors and “sophisticated” investors. The latter tend to be wealthier and/or more experienced investors who have a better understanding of the risks involved in investing in securities that are not listed and therefore have fewer disclosures. Because of their economic status, they are also in a better financial position to absorb potential losses from riskier investments. Retail investors, in contrast, are less sophisticated and are less able to absorb losses and therefore the financial products they are offered are more tightly regulated. In the EU, sophisticated investors are known as “professional clients.”  In the United States they are known as “accredited investors” (see above).  Typically the financial regulator establishes qualitative and/or quantitatives tests for determining who meets the definition of “sophisticated” investor.
