Investment Thesis:

responsAbility’s goal is to create development impact while also unlocking attractive new markets for private, institutional and public investors. Our investment solutions supply debt and equity financing to non-listed companies in emerging and developing economies, in the areas of financial inclusion, sustainable food and climate finance.

Investment Overview:

responsAbility’s investment focus is on development-related sectors of emerging economies, which comprise the areas of financial inclusion, sustainable food and climate finance. responsAbility makes investments – in the form of private debt or private equity – in companies with significant growth potential whose business models can overcome one or more of the following obstacles in an innovative manner: a lack of availability, affordability and/or a lack of suitability of core products and services. The companies must also be capable of efficiently expanding their activities in order to reach an increasing number of people (ability to scale). responsAbility considers responsible conduct towards clients as well as the environment, employees and other stakeholders to be an inherent part of a sustainable business approach that focuses on the achievement of long-term success.

Investment Example

Kaebauk Investimentu No Finansas (KIF) is the largest microfinance institution in Timor-Leste, established in 2001 to support post-conflict recovery and economic growth. Aligned with the United Nations Sustainable Development Goals (SDGs), KIF focuses on empowering women and underserved rural communities. Over 58% of its clients are women, and 80% reside in remote areas. Originally created to support communities after political conflict, KIF now offers financial services across all 13 districts, emphasizing economic resilience and inclusive growth. A prominent success story is Mrs. Teresinha de Araujo, who rebuilt and expanded her business after receiving a small KIF loan in 2006, venturing into public transportation, truck rentals, and hospitality, all while securing education for her children. With a loan portfolio of over USD 28 million and around 18,464 clients, KIF plays a vital role in reducing poverty, fostering economic development, and creating sustainable growth opportunities throughout Timor-Leste.

Investments systematically target companies where social and/or environmental impact is integral to the product/service being created:

responsAbility sets impact objectives for each of its funds at inception (increase financial inclusion, improve access to electricity, reduce C02 emissions etc.) that determines the fund’s investment universe and eligibility criteria on the type of portfolio companies as well as the countries the fund can invest in. responsAbility reviews the overall eligibility of a company according to this predetermined list of eligibility criteria as early as possible during the investment process, an approach that is rather unique in the finance industry. This ensures that the investment universe is delimited in a way that leaves only portfolio companies eligible for investment that provide the impact responsAbility targets. Only if a portfolio company passed this initial step, our analysis focuses on risk/return parameters in order to determine a portfolio fit with regards to financial parameters. Eligibility criteria are reviewed periodically to ensure our investment universe fits the impact objectives of the fund.

Investments systematically include social and environmental sustainability practices in the due diligence process:

responsAbility’s ESG principles and strategy are captured in its corporate ESG Policy, which is then translated by every investment team into a specific ESG process and a set of ESG tools that allows them to evaluate the relevant ESG risks of each potential investment. Prior to any investment, all potential portfolio companies are screened against the Fund’s ESG Exclusion List (i.e. no forced labour, weapons and munitions, corrupt practices, money laundering, etc.) and eligibility criteria are applied to all our investments, including multiple criteria relating to both ESG and impact. However, these criteria will vary according to the type of business model under consideration. Each proposed investment is categorized as ‘low’, ‘medium’ or ‘high’ to its ESG risks, in line with the IFC standards. ESG risks are then assessed through an ESG Due Diligence before investment. The results and mitigation actions are included in the investment documentation and closely monitored.
