For me it looks like a restructuring situation. Melissa was in Ed's team, so not interested about taking out all the mess, as it was partially her mess. Once the new guy comes in he may take out a few dead bodies from the closet, make new reserves for portfolios and replace some people below him, potentially CFO. It will take some time to fix on a challenging market.
Wasn't the guidance about 2019 only?
But overall its a positive change (base effect I guess), but not without its risks.
