The Corporation consider s a loan as adversely classified if its risk rating is Substandard, Doubtful or Loss. These categories are defined as follows: Substandard- A Substandard as set is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful- Doubtful classifications have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable. A Doubtful classification may be appropriate in cases where significant ris k exposures are perceived, but l oss cannot be determined because of specific reasonable pending factors , which may strengthen the credit in the near term. Loss- Assets classified Loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. There is little or no prospect for near term improvement and no realistic strengthening action of significance pending.

The Corporation also acquired PCI loans in previous ly completed asset acquisitions which are accounted for under ASC 310-30. These previous transactions include the acquisition from Doral Financial in the second quarter of 2014 of all its rights, title and interest in fi rst and second residential mortgages loans in full satisfaction of secure d borrowings owed by such entity to FirstBank , and the acquisition in 2012 of a FirstBank-branded credit card loans portfolio from FIA Card Services (“FIA”). Under ASC 310-30, the acquired PCI loans were aggregated into pools based on similar characteristics (i.e. delinquency status, loan terms). Each loan pool is accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. Since t he loans are accounted for by the Corporation under ASC 310-30 , they are not considered non-performing and will continue to have an accretable yield as long as there is a reasonable expectation about the timing and amount of cash flows expected to be collected. The Corporation recognizes additional losses on this portfolio when it is probable that the Corporation will be unable to collect all cash flows expected a s of the acquisition date plus additional cash flows expected to be collected arising from changes in estimates after the acquisition date .

Under the accounting guidance for PCI loans, the difference between the contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non - accretable difference. This difference is neither accreted into income nor recorded on the Corporation's consolidated statement of financial condition. The excess of cash flows expected to be collected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loans, using the effective-yield method. Changes in accretable yield of acquired loans Subsequent to acquisition, the Corporation is required to periodically evaluate its estimate of cash flows expected to be collected. These evaluations, performed quarterly, require the continued use of key assumptions and estimates, similar to the initial estimate of fair value. Subsequent changes in the estimated cash flows expected to be collected may result in changes in the accretable yield and non - accretable difference or reclassifications from nonaccretable yield to accretable yield . Increases in the cash flows expected to be collected will generally result in an increase in interest income over the remaining life of the loan or pool of loans. Decreases in expected cash flows due to further credit deterioration will generally result in an impairment charge recognized in the Corporation's provision for loan and lease losses, resulting in an increase to the allowance for loan losses. During the first quarter of 2016, the Corporation increased by $0.6 million to $4.6 million the reserve related to PCI loans acquired from Doral Financial in 2014. The reserve is driven by the revisions to the expected cash flows of the portfolio for the remaining term of the loan pool based on market conditions. Changes in the accretable yield of PCI loans for the quarters ended March 31, 2016 and 2015 were as follows: March 31, 2016 March 31, 2015 (In thousands) Balance at beginning of period $ 118,385 $ 82,460 Additions (accretable yield at acquisition of loans from Doral Bank) - 38,319 Accretion recognized in earnings (2,889) (2,277) Reclassification to non-accretable (1,398) - Balance at end of period $ 114,098 $ 118,502 Changes in the carrying amount of loans accounted for pursuant to ASC 310-30 follows: Quarter ended Quarter ended March 31, 2016 March 31, 2015 (In thousands) (In thousands) Balance at beginning of period $ 173,913 $ 102,604 Additions - 79,889 Accretion 2,889 2,277 Collections (4,371) (3,656) Foreclosures (99) - Ending balance $ 172,332 $ 181,114 Allowance for loan losses (4,568) - Ending balance, net of allowance for loan losses $ 167,764 $ 181,114 Changes in the allowance for loan losses related to PCI loans follows: Quarter ended Quarter ended March 31, 2016 March 31, 2015 (In thousands) (In thousands) Balance at beginning of period $ 3,962 $ - Provision for loan losses 606 - Balance at the end of period $ 4,568 $ - The outstanding principal balance of PCI loans, including amounts charged off by the Corporation, amounted to $ 216.1 million as of March 31, 201 6 (December 31, 201 5 - $ 218.1 million). Purchases and Sales of Loans D uring the first quarter of 201 6 , the Corporation purchased $ 19.1 million of residential mortgage loans consistent with a strategic program established by the Corporation in 2005 to purchase ongoing residential mortgage loan production from m ortgage bankers in Puerto Rico . Generally, the loans purchased from mortgage bankers were conforming residential mortgage loans. Purchases of conforming residential mortgage loans provide the Corporation the flexibility to retain or sell the loans, including through securitization transactions , depending upon the Corporation 's interest rate risk management strategies. When the Corporation sells such loans, it generally keeps the servicing of the loans. In the ordinary course of business, the Corporation sells residential mortgage loa ns (originated or purchased) to GNMA and governm ent-sponsored entities (“GSEs”) such as Fannie Mae (“FNMA”) and Freddie Mac (“FHLMC”), which generally securitize the transferred loans into mortgage-backed securities for sale into the secondary market. The Corporation sold approximately $ 3 8.3 million of performing residential mortgage loans to FNMA and FHLMC during the first quarter of 201 6 . Also, during the first quarter of 2016, the Corporation s old $ 67.7 million of FHA/VA mortgage loans t o GNMA , which packages them into mortgage-backed securities . The Corporation's continuing involvement in these loan sales consists primarily of servicing the loans. In addition, the Corporation agreed to repurchase loans when it breaches any of the representations and warranties included in the sale agreement. These representations and warranties are consistent with the GSEs' selling and servicing guidelines (i.e., ensuring that the mortgage was properly underwritten according to established guidelines). For loans sold to GNMA, the Corporation holds an option to repurchase individual delinquent loans issued on or after January 1, 2003 when the borrower fails to make any payment for three consecutive months. This option gives the Corporation the ability, but not the obligation, to repurchase the delinquent loans at par without prior authorization from GNMA. Under ASC 860 , Transfer and Servicing , once the Corporation has the unilateral ability to repurchase the delinquent loan, it is considered to have regained effective control over the loan and is required to recognize the loan and a corresponding repurchase liability on the balance sheet regardless of the Corporation's intent to repurchase the loan. During the first quarter of 201 6 and 2015 , the Corporation repurchased pursuant to its repurchase option with GNMA $ 8.4 million and $ 3.0 million, respectively, of loans previously sold to GNMA. The principal balance of these loans is fully guaranteed and the risk of loss related to the repurchased loans is generally limited to the difference between the delinquent interest payment advanced to GNMA computed at the loan's interest rate and the interest payments reimbursed by FHA, which are computed at a pre-determined debenture rate. Repurchases of GNMA loans allow the Corporation, among other things, to maintain acceptable delinquency rates on outstanding GNMA pools and remain as a seller and servicer in good standing with GNMA. The Corporation generally remediates any breach of representations and warranties related to the underwriting of such loans according to established GNMA guidelines without incurring losses. The Corporation does not maintain a liability for estimated losses as a result of breaches in representations and warranties. Loan sales to FNMA and FHLMC are without recourse in relation to the future performance of the loans. The Corporation repurchased at par loans previously sold to FNMA and FHLMC in the amount of $ 0.5 million and $ 0.2 million during the first quarter of 201 6 and 2015, respectively . The Corporation's risk of loss with respect to these loans is also minimal as these repurchased loans are generally performing loans with documentation deficiencies. No losses related to bre a ches of representations and warranties were incurred in the first quarter of 201 6 . Historically, losses experienced on these loans have been immaterial . As a consequence, as of March 31, 201 6 , the Corporation does not maintain a liability for estimated losses on loans expected to be repurchased as a result of breaches in loan and servicer representations and warranties. Loan Portfolio Concentration The Corporation's primary lending area is Puerto Rico. The Corporation's banking subsidiary, First Bank, also lends in the USVI and BVI markets and in the United States (principally in the state of Florida). Of the total gross loans held for investment of $ 9.1 billion as of March 31, 201 6 , approximately 80 % have credit risk concentration in Puerto Rico, 13 % in the United States, and 7 % in the USVI and BVI. As of March 31, 201 6 , the Corporation had $ 315.6 million of credit facilities , excluding investment securities, extended to the Puerto Rico government, its municipalities and public corporations, of which $ 302.2 million was outstanding (book value of $ 297.2 million) , compared to $ 3 14.6 million outstanding as of December 31, 201 5 . In addition, the outstanding balance of facilities granted to the government of the Virgin Islands amounted to $ 67.4 million as of March 31, 201 6 , compared to $ 126.2 million as of December 31, 201 5 . Approximately $ 199.3 million of the granted credit facilities outstanding consist ed of loans to municipalities in Puerto Rico whose revenues are independent of the Puerto Rico central government . Municipal debt exposure is secured by ad valorem taxation without limitation as to rate or amount on all taxable property within the boundaries of each municipality. The good faith, credit, and unlimited taxing power of the applicable municipality have been pledged to the repayment of the municipality's loans . Approximately 88 % of the Corporation's municipality exposure consists primarily of senior priority loans concentrated on five of the largest municipalities on Puerto Rico (San Juan, Carolina, Bayamon, Mayaguez and Guaynabo). These municipalities are required by law to levy special property taxes in such amounts as req uired for the payment of all their respective gen eral obligation bonds and loans . In addition to municipalities, loans extended to the Puerto Rico Government include $ 6.9 million of loans to units of the Puerto Rico central government, and approxi |
