Adam S. Wallwork is in the firm's Public Finance and Tax Departments and is also part of the Tax Credits and Virtual Currency Teams. He acts as special tax counsel, bond counsel, underwriter's counsel, borrower's counsel, trustee's counsel, and counsel to banks providing credit enhancements for museums, universities, long-term care providers, and affordable housing developers across the country. His practice focuses on a range of U.S. federal, state, and local tax issues that arise for investors, sponsors, underwriters, and issuers in securitized and structured finance transactions. He also works with domestic and foreign multinationals on U.S. federal income tax and reporting obligations arising from transactions between affiliates, prepaid contracts, mergers, acquisitions, swaps, hedges, and derivatives. Adam's practice also deals with U.S. tax aspects of inbound investments by foreign persons in the United States, investments abroad by U.S. persons, and cross-border transfers of assets, including virtual currency and real estate, into and out of corporate solution.

Adam provides tax-exempt and tax-advantaged financing solutions for municipalities, non-profit organizations, and private developers to reduce their borrowing costs for projects that provide clean energy, preserve public landmarks, renew blighted districts, and increase affordable housing in the community. Federal investment tax credits for renewable energy, affordable housing, and opportunity zone projects provide favorable tax-exempt and tax advantaged financing options for both non-profit and for-profit businesses, which can often be combined with credit enhancements (such as PACE loans secured by local property tax assessments). He has extensive experience working on solar securitizations, including underwriting tax-credit syndication structures in the largest publicly-offered residential solar securitization to date, and was involved in litigating the seminal case on federal investment tax credits, Historic Boardwalk Hall v. Commissioner of Internal Revenue. He regularly counsels developers on tax-exempt municipal financing structures that also leverage a project's tax equity to significantly reduce the borrower's debt service costs.

Representative matters include:

  • Developing a tax-increment financing structure that allowed a municipality to use its share of casino revenue to secure low-rate tax-exempt financing of a local redevelopment project
  • Providing U.S. tax advice on more than $10 billion in currency, interest-rate, and commodities swaps
  • Structuring a tax-free transfer of Bitcoins held offshore by U.S. owners of an online gaming platform
  • Advising an insurance company on billions of dollars in underwriting tax risks for publicly-offered solar securitizations and renewable energy tax credit investment structures
  • Counseling a municipality on general public use requirements for an affordable housing project financed by tax-exempt bonds and low-income housing tax credit
  • Drafting official statements and tax compliance certificates for a municipality's conduit financing of a non-profit's retirement communities
  • Drafting U.S. tax disclosures and opinions for multinational companies in their issuance of credit card and auto receivables-backed notes in the United States under S.E.C. Rule 144A
  • Advising museums, universities, and utility companies on tax and compliance issues related to their respective interest-rate, foreign-currency, and commodity swaps
  • Planning a foreign multinational's tax-free transfer of more than a billion dollars of U.S. real property interests pursuant to a merger
  • Designing a tax-efficient REIT structure for a foreign pension fund to hold several U.S. apartment buildings without incurring U.S. federal income taxes or filing obligations under the Foreign Investment in Real Property Tax Act of 1980 (FIRPTA)
  • Evaluating tax accounting consequences of 2017 Tax Reform Act on prepaid gas supply contracts with municipalities across the southeastern United States worth several billion dollars
