The hotelier swung to a loss in the quarter due to costs stemming from the ongoing spinoff of its timeshare business. Those costs masked stronger earnings driven by higher revenue in most regions.

Hotel real estate investment trusts were the worst performing in the sector last quarter slumping roughly 30%. Get the full story at The Wall Street Journal
