SAN JUAN, Puerto Rico, Muharram 26, 1437, November 08, 2015, SPA -- Puerto Rico's government will likely have to cut back on public services or default on debts before the end of the year because it is running out of cash, the Government Development Bank said in a financial filing, AP reported. Putting numbers to a warning this summer from Gov. Alejandro Garcia Padilla, the filing late Friday said the U.S. territory had a $370 million overdraft as of Sept. 30 and burned through a $400 million emergency loan from a group of public corporations to keep government operating. It also cut revenue estimates for the current fiscal year by $355 million because of weaker than expected collections. The development bank, which has been the lender of last resort for the island's cash-strapped government, may be insolvent by year's end, the report added. To conserve cash, officials have been holding back payments to suppliers and tax rebates to taxpayers and they are now discussing cutting employee work schedules by two days a week. They have warned that maintaining essential services in the areas of health, education and public safety may force them to institute a debt payment moratorium. The island is struggling to get out of a nearly decade-long slump that has reduced government revenues and spurred a growing exodus of islanders to the U.S. mainland to look for work. --SPA 00:51 LOCAL TIME 21:51 GMT www.spa.gov.sa/w
