Even if the legal impacts of post-recession policies such as the Dodd-Frank Wall Street Reform and Consumer Protection Act and the JOBS Act remain open to debate, there's no question that the economic downturn left its mark on the financial world - and on its argot. And nowhere is it more important to get your lingo lined up than in legal proceedings. So Latham & Watkins has issued a second edition of the Book of Jargon: US Corporate and Bank Finance, its free print and online glossary of all terms financial, now also available as an app. The firm offers six other Jargon titles in various fields of business and transactional law, along with two apps for global guidance on merger laws, and on bribery and corruption. (Find them at www.lw.com under the "Knowledge Library" tab.) Financial lingo has evolved significantly since the first edition of the U.S. finance app came out in 2008, says partner and project leader Tad Freese, a co-chair of Latham's global corporate practice in Menlo Park. "In a world where financing - and financing options - are getting more and more complicated, we thought it would be very helpful for everyone from corporate directors to other lawyers ... to have one place to look things up," Freese says. This is a world where minimum hold and mini perm have nothing to do with a hairdresser's services. It's a world where even account has a special meaning - and where you don't want an average life, at least not personally. It's likely that experienced corporate lawyers already know most of the terminology, says Freese. The book is geared more toward clients, board members, and investment bankers and lawyers who are just learning this complex arena. The endeavor took thousands of attorney and staff hours to complete, but Freese says it's been fun - and great for business development.
