[1] Amount excludes purchased-credit impaired ("PCI") loans with a carrying value of approximately $160.4 million and $165.8 million as of June 30, 2017 and December 31, 2016, respectively, primarily mortgage loans acquired from Doral Bank in the first quarter of 2015 and from Doral Financial in the second quarter of 2014, as further discussed below. These loans are not considered non-performing due to the application of the accretion method, under which these loans will accrete interest income over the remaining life of the loans using an estimated cash flow analysis.

[2] As of June 30, 2017 and December 31, 2016, excludes $8.1 million of non-performing loans held for sale.
