Kraft Heinz, under the leadership of private equity firm 3G Capital Partners LP, has impressed investors with its ability to drastically reduce expenses following its merger in 2015. Perhaps this should not come as a particular surprise - after all 3G Capital is known for its zero-base budgeting approach that calls for departments to justify every dollar they spend each year. Budgeted costs are evaluated unsparingly and reduced or eliminated if they are no longer deemed to be necessary.
