Net interest income, interest rate spread, and net interest margin are reported excluding the changes in the fair value of derivative instruments and on a tax-equivalent basis in order to provide to investors additional information about the Corporation’s net interest income that management uses and believes should facilitate comparability and analysis. The changes in the fair value of derivative instruments have no effect on interest due or interest earned on interest-bearing liabilities or interest-earning assets, respectively. The tax-equivalent adjustment to net interest income recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a marginal income tax rate. Income from tax-exempt earning assets is increased by an amount equivalent to the taxes that would have been paid if this income had been taxable at statutory rates. Management believes that it is a standard practice in the banking industry to present net interest income, interest rate spread, and net interest margin on a fully tax-equivalent basis. This adjustment puts all earning assets, most notably tax-exempt securities and tax-exempt loans, on a common basis that facilitates comparison of results to the results of peers.

The tangible common equity ratio and tangible book value per common share are non-GAAP financial measures generally used by the financial community to evaluate capital adequacy. Tangible common equity is total equity less preferred equity, goodwill, core deposit intangibles, and other intangibles, such as the purchased credit card relationship intangible and the insurance customer relationship intangible. Tangible assets are total assets less goodwill, core deposit intangibles, and other intangibles, such as the purchased credit card relationship intangible and the insurance customer relationship intangible. Management and many stock analysts use the tangible common equity ratio and tangible book value per common share in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, typically stemming from the use of the purchase method of accounting for mergers and acquisitions. Accordingly, the Corporation believes that disclosures of these financial measures may be useful also to investors.  Neither tangible common equity nor tangible assets, or the related measures should be considered in isolation or as a substitute for stockholders’ equity, total assets, or any other measure calculated in accordance with GAAP. Moreover, the manner in which the Corporation calculates its tangible common equity, tangible assets, and any other related measures may differ from that of other companies reporting measures with similar names.

Adjusted pre-tax, pre-provision income is a non-GAAP performance metric that management uses and believes that investors may find useful in analyzing underlying performance trends, particularly in times of economic stress, including as a result of natural catastrophes such as the recent hurricanes.  Adjusted pre-tax, pre-provision income, as defined by management, represents net income (loss) excluding income tax expense (benefit) and the provision for loan and lease losses, as well as certain items that management believes are not reflective of core operating performance, are not expected to reoccur with any regularity or may reoccur at uncertain times and in uncertain amounts.

Adjusted provision for loan and lease losses, adjusted net charge-offs and the ratios of adjusted net charge-offs to average loans, adjusted provision for loan and lease losses to net charge-offs, and the adjusted allowance to total loans held for investment are non-GAAP financial measures that excludes the effects related to: (a) a $6.4 million net loan loss reserve release recorded in the first quarter of 2018 in connection with revised estimates of the reserve associated with the effects of Hurricanes Maria and Irma, (b) a $5.6 million charge to the provision associated with commercial and construction loans transferred to held for sale in the first quarter of 2018, (c) a $4.8 million incremental provision expense recorded in the fourth quarter of 2017 associated with the estimate of inherent losses resulting from the impact of Hurricanes Maria and Irma, and (d) the effect related to the sale of the Corporation’s participation in the Puerto Rico Electric Power Authority (“PREPA”) line of credit in the first quarter of 2017.  Management believes that this information helps investors understand the adjusted measures without regard to items that are not expected to reoccur with any regularity or may reoccur at uncertain times and in uncertain amounts on reported results and facilitates comparisons with prior periods.

Adjusted non-interest income that excludes the effect of a gain on the repurchase and cancellation of trust preferred securities in the first quarter of 2018 and the effect of other-than-temporary impairment charges on debt securities recorded in the first quarter of 2017. Management believes that the exclusion from non-interest income of items that are not expected to reoccur with any regularity or may reoccur at uncertain times or in uncertain amounts facilitates comparisons with prior periods, and provides an alternate presentation of the Corporation’s performance.

6.

Adjusted non-interest expenses that reflect the exclusion of storm-related expenses  such as insurance deductibles related to damages assessed on certain other real estate owned (“OREO”) properties and other estimated storm-related costs associated with the effects of Hurricanes Irma and Maria in the first quarter of 2018 and fourth quarter of 2017, inclusion of expected insurance recoveries for rental costs that the Corporation incurred when Hurricanes Irma and Maria precluded employees from working during the fourth quarter of 2017, and the exclusion of costs associated with a secondary offering of the Corporation’s common stock by certain of the existing stockholders in the first quarter of 2017.    Management believes that adjustments to non-interest expenses of items that are above normal or recurring levels, are not expected to reoccur with any regularity or may reoccur at uncertain times and in uncertain amounts facilitate comparisons with prior periods, and provides an alternate presentation of the Corporation’s performance.

7.

Adjusted net income that reflects the effect of a tax benefit recorded in the first quarter of 2017 related to the change in tax status of certain subsidiaries from taxable corporations to limited liability, and the effect of all the items mentioned above and their tax related impacts. Management believes that adjustments to net income of items that are not reflective of core operating performance, are not expected to reoccur with any regularity or may reoccur at uncertain times and in uncertain amounts facilitate comparisons with prior periods, and provides an alternate presentation of the Corporation’s performance.
