From the Summary: "The government of Puerto Rico faces multiple fiscal challenges in the fall of 2015. Concerns regarding the sustainability of Puerto Rico's public finances have intensified over the past year, despite several measures taken by the island's government to reduce spending, increase revenues, and restructure its obligations. The Puerto Rican government outlined a medium-term strategy to address those challenges in a fiscal plan put forth in mid-September 2015."
