Daniel H Mathias spoke with S&P Global about London’s efforts to pry away listings of special purpose acquisition companies (SPACs) from other financial hubs by easing some of its rules.

“Timing is certainly relevant and, indeed some people in the market have questioned the UK changes coming months after the most recent U.S. listings peak,” said Mathias. “But the new rules have merit from a long-term perspective, given that SPACs will remain a capital-raising option and, prior to the amendments, the U.K. was "out of step" with other jurisdictions”, he said. The presumption of suspension and the lack of redemption option, which allows SPAC investors to exit their shareholding before an acquisition is completed, were key deterrents before the change, according to Mathias.

“As the U.S. is a huge market with lots of knowledge around SPACs, there will be a need to create a compelling story as to why these vehicles should be listed in London”, Cohen & Gresser's Mathias said.

Daniel H Mathias spoke with Law360 about the UK’s adoption of friendlier rules governing special purpose acquisition companies (SPACs) – an alternative vehicle to public markets. Dan spoke about the historically low level of SPACs in the UK and noted that "it wouldn't take much for a significant increase.”

As SPACs appear to get a stronger foothold in the U.K. and Europe, Mathias said regulators appear to be taking a “wait and see” approach in terms of next steps. The FCA said it will monitor how its rules play out, observing market trends, evidence of misconduct, or other indicators to decide whether more stringent rules are needed.”

There’s a realization by everybody that SPACs are likely to stay as an option in the M&A and capital markets world,”  Mathias said. “I think all the regulators in Europe are realizing that and trying to navigate their way through that.”

Bonnie Roe is quoted in the latest “Accounting & Compliance Alert” for Thomson Reuters about the top accounting issues that target private companies and SPACs must consider when deal-making.

Bonnie notes that the biggest issue for companies rushing to go public via SPAC (termed “De-SPACing”) is potentially having to get auditor attestation of your internal controls in your first year, depending on the status of the SPAC partner. Bonnie continues “[that] basically means that before you do the transaction you have to have started the process that would enable you to do an audit of your internal controls for the year that you were in.”

Cohen & Gresser represented Imagine Software, a leading global portfolio risk management technology company, in its sale to Francisco Partners, a global investment firm that specializes in partnering with technology and technology-enabled businesses. Francisco Partners has announced that it will combine Imagine Software with the recently acquired TradingScreen to form TS Imagine – a new dynamic end-to-end trading and portfolio management software platform that will be one of the most robust SaaS cloud-based software platforms in capital markets and investment management. The combined company will offer integrated and complete front office solutions, complementary product capabilities, best-in-class technology, global geographic coverage, and deep expertise to investment firms and financial institutions around the world. The C&G team representing Imagine Software in its sale to Francisco Partners included Lawrence T Gresser, Kwaku Andoh, Karen H Bromberg, Bonnie J Roe, Nicholas J Kaiser, Ronald F Wick, Alexandra K Theobald, and Drew S Dean. Learn more about the deal in Francisco Partners’ press release.
