A&O Shearman partner Lorenz Haselberger publishes article on recent IRS advice memoranda relevant to inbound debt acquisitions and sourcing of income

In his recent article “ECI Nailed; Sourcing Failed: The Curious Case of the Recent Repo CCAs,” published in the Journal of Taxation of Financial Products on April 15, A&O Shearman partner Lorenz Haselberger analyzes the IRS Office of Chief Counsel’s advice memoranda 202548005 and 202548004 (the “CCAs”).   

The CCAs consider whether certain U.S.-managed offshore hedge funds that regularly entered into securities repos with their U.S. prime brokers were thereby engaged in a U.S. trade or business or derived U.S.-source income subject to federal withholding tax.   

Haselberger identifies practical areas in which the CCAs provide welcome guidance for offshore investors and lenders, focusing on the implications of the CCAs’ U.S. trade or business determination for inbound investments in U.S. corporate loans as well as securities-backed lending. He also examines the CCAs’ sourcing analysis, explaining why it is unpersuasive and should not alter existing approaches to sourcing income by analogy.
