Unusual Or Infrequent Items Disclosure Text Block	NOTE 2 – SIGNIFICANT EVENTS Hurricanes Irma and Maria During 2017, Oriental was impacted by hurricanes Irma and Maria, which struck the Island on September 7, 2017 and September 20, 2017, respectively. Hurricane Maria caused catastrophic damages throughout Puerto Rico, including homes, businesses, roads, bridges, power lines, commercial establishments, and public facilities. It caused an unprecedented crisis when it ravaged the Island’s electric power grid less than two weeks after hurricane Irma left over a million Puerto Rico residents without power. For several months after the hurricanes, a large part of Puerto Rico was and some areas still remain without electricity, many businesses were unable to operate, and government authorities struggled to deliver emergency supplies and clean drinking water to many communities outside the San Juan metropolitan area. Further, payment and delivery systems, including the U.S. Post Office, were unable to operate for weeks after hurricane Maria. Almost all of Oriental’s operations and clients are located in Puerto Rico. Although Oriental’s business operations were disrupted by major damages to Puerto Rico’s critical infrastructure, including its electric power grid and telecommunications network, Oriental’s digital channels, core banking and electronic funds transfer systems continued to function uninterrupted during and after the hurricanes. Within days after hurricane Maria, and upon securing a continuing supply of diesel fuel for its electric power generators, Oriental was able to open its main offices and many of its branches and ATMs in addition to its digital and phone trade channels. As a result of this event, and based on current assessments of information available for the impact of the hurricanes on our credit portfolio, 2017 results included an additional $32.4 million in loan loss provision, pre-tax.

To operate in disaster response mode, the Oriental incurred expenses for, among other things, buying diesel and generators for electric power, debris removal, security matters, property damages, and emergency communication with customers regarding the status of Bank operations. The total estimated total losses as of December 31, 2017 amounted to $6.6 million. Oriental maintains insurance for casualty losses as well as for disaster response costs and certain revenue lost through business interruption. Management believes that recovery of $2.2 million incurred costs as of December 31, 2017 is probable. Oriental received a $1.0 million partial payment from the insurance company during December 2017. Accordingly, a receivable of $1.2 million was included in other assets as of December 31, 2017 for the expected recovery.
