When a company makes more than 25 acquisitions a year, as Google recently did, a key cash management challenge is locking down the target company’s cash as soon as the deal is signed. “When a company changes hands,” notes Kenny Tse, a treasury analyst II at Google, “there’s a tremendous risk of fraud. Individuals could make off with hundreds, thousands or even millions of dollars. No amount of hedging or insurance can cover losses due to poor control of funds.” That’s why Google treasury perfected a system that over a recent one-year period seized more than $3.5 billion in cash in more than 400 bank accounts in more than 50 countries just as soon as deals closed. Not a penny was lost.
