Mayer Brown maintains an avid awareness of the impact our business has and we are committed to doing business in ways that enhance our local communities and reduces the impact on the environment. We also have a long-standing commitment to promoting and developing innovative financial solutions that advance social causes.

We advise banks, funds, investment platforms and other entities that create opportunities, which generate social good and meaningful impact. Clients also include Community Development Financial Institutions (CDFIs), governments, donor groups, and impact-oriented organizations addressing on issues such as housing, microfinance and micro-insurance, water and sanitation, education, healthcare, and energy.

Our strengths in securities and capital markets, mergers and acquisitions, private funds, regulatory and corporate law—combined with our global resources—inform our advice in complex transactional matters related to social and impact finance.

Our lawyers are thought leaders in the social and impact investing sector and have written articles published by the Stanford Social Innovation Review and Federal Reserve Bank of San Francisco. We teach microfinance classes in leading academic programs, speak on panels and seminars on social and impact finance issues, write handbooks on these matters, and counsel senior management of leading microfinance and social finance organizations.

The financial products developed by Mayer Brown lawyers are recognized for their innovative nature. As the Financial Times notes in their coverage of our lawyers’ work with client NPX, “Creating innovative financing mechanisms that help protect the environment or alleviate poverty demands the same skills lawyers use in their commercial work.”

We work with clients on new products and new proprietary indices, including many focused on social impact. Mayer Brown’s leadership in the green and sustainability bond markets is equally notable, as we have been one of the few global law firms to work on a variety of green and sustainability bonds as well as social bonds across various markets, including the United States, Europe and Asia.

We work closely with financial institutions to create and structure innovative financing techniques, including new securities distribution methodologies and financial products. In addition to advising on green bonds, we advise clients on green structured notes, green covered bonds, charitable structured notes, and ESG structured notes.

As the interest in all things environmental, social, and governance-related has increased, Mayer Brown maintains a strong track record helping clients address their ESG issues. Learn more about our ESG capabilities.


Representative Matters

The Impact Security. NPX Advisors and Mayer Brown lawyers developed the innovative Impact Security.

Calvert Impact Capital. We represented InspereX (formerly Incapital), as lead dealer, and the dealers, in connection with the Calvert Impact Capital Community Investment Notes® program. Community Investment Notes are debt securities issued by Calvert Impact Capital that channel capital to high-impact community development initiatives in the U.S. and around the world. When it was commenced, Calvert was the first continuously offered notes program by a non-profit issuer.

CDFI Bond Issuances. We have been at the forefront of impact investing, advising on the first-of-its-kind bond issuances by Community Development Financial Institutions (“CDFIs”), including advising:

  • InspereX (formerly Incapital), as lead dealer, and other dealers, in connection with Century Housing’s $100 million muni bond. Century Housing, a California-based CDFI, delivers innovative financial products quickly and reliably to support the development of critical housing projects in underserved communities. In June 2020, through the California Municipal Finance Authority, a conduit municipal agency, Century Housing issued $100 million of an ESG municipal CUSIP bond (“muni bond”). The issuance marked the first time a CDFI came to market with a muni bond CUSIP and the first time a CDFI was rated by two ratings agencies, Fitch and S&P. The muni bond will be used to construct or preserve more than 2,000 affordable housing units. Environmental Finance awarded Century Housing the “Sustainable bond of the year – US muni bond” at its 2021 Bond Awards for its 2020 muni bond.
  • InspereX, and the dealers, in connection with the issuance of LISC Impact Notes by the Local Initiatives Support Corporation (“LISC”). LISC is a CDFI that provides financing and technical assistance to low-wealth individuals underserved by the financial markets. LISC supports community development initiatives in 35 cities and across 2,100 rural counties in 44 states. LISC issued $150 million of LISC Impact Notes in November 2020. The issuance of LISC Impact Notes aims to build economic opportunity, support healthy communities and bridge the racial wealth gap in the U.S. This was just the second time that a CDFI has offered notes that are S&P-rated, DTC-settled and available on a continuous basis through brokerage accounts in most U.S. states. Environmental Finance awarded LISC the “Social bond of the year – corporate” at its 2021 Bond Awards for its 2020 LISC Impact Notes issuance.
  • InspereX, and the dealers, in connection with the issuance of Capital Impact Investment Notes by Capital Impact Partners. Capital Impact Partners is a CDFI that works to deliver social and financial impact through its mission-driven financing and technical assistance to support organizations that foster equity, opportunity and healthy communities nationwide. In August 2021, Capital Impact Partners issued over $200 million of Capital Impact Notes, the net proceeds of which help drive social impact through investment in organizations that provide access to critical social services, including health care, education, affordable housing, and healthy foods.
