NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1 Basis of Presentation

 

National Bank Holdings Corporation ("NBHC" or the "Company") is a bank holding company that was incorporated in the State of Delaware in 2009 with the intent to acquire and operate financial services franchises and other complementary businesses in targeted markets. The Company is headquartered immediately south of Denver, in Greenwood Village, Colorado, and its primary operations are conducted through its wholly owned subsidiary, NBH Bank, (the "Bank"), a Colorado state-chartered bank and a member of the Federal Reserve System. The Company provides a variety of banking products to both commercial and consumer clients through a network of 104 banking centers located primarily in Colorado and the greater Kansas City region, and through online and mobile banking products and services. On January 1, 2018, the Company completed the acquisition of Peoples, Inc. Refer to note 3 – Acquisition Activities for further details.

 

The accompanying interim unaudited consolidated financial statements serve to update the National Bank Holdings Corporation Annual Report on Form 10-K for the year ended December 31, 2017 and include the accounts of the Company and its wholly owned subsidiary, NBH Bank. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies. However, they may not include all information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods and accordingly should be read in conjunction with the financial information contained in the Company's most recent Form 10-K. The unaudited consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results presented. All such adjustments are of a normal recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications of prior years' amounts are made whenever necessary to conform to current period presentation The results of operations for the interim period is not necessarily indicative of the results that may be expected for the full year or any other interim period. All amounts are in thousands, except share data, or as otherwise noted.

 

GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. By their nature, estimates are based on judgment and available information. Management has made significant estimates in certain areas, such as the amount and timing of expected cash flows from assets, the valuation of other real estate owned (“OREO”), the fair value adjustments on assets acquired and liabilities assumed, the valuation of core deposit intangible assets, the valuation of investment securities for other-than-temporary impairment (“OTTI”), the valuation of stock-based compensation, the fair values of financial instruments, the allowance for loan losses (“ALL”), and contingent liabilities. Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from those estimates.

 

Beginning in the first quarter 2018, loans previously referred to as "non 310-30 loans" are referred to as "originated and acquired loans," which include acquired loans not accounted for under ASC 310-30. No amounts were reclassified resulting from this change in terminology.

 

The Company's significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in note 2 of the audited financial statements and notes for the year ended December 31, 2017 and are contained in the Company's Annual Report on Form 10-K. There have not been any significant changes to the application of significant accounting policies since December 31, 2017, except for the following additions:

 

Mortgage Servicing– Mortgage servicing rights (“MSRs”) associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and included in intangible assets, net on the consolidated statements of financial condition. For subsequent measurement purposes, the Company measures servicing assets based on the lower of cost or market using the amortization method. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned. The carrying values of these rights are reviewed quarterly for impairment based on the fair value of those assets. For purposes of impairment evaluation and measurement, management stratifies MSRs based on the predominant risk characteristics of the underlying loans, including loan type and loan term. If, by individual stratum, the carrying amount of these MSRs exceeds fair value, a valuation allowance is established and the impairment is recognized in mortgage banking income. If the fair value of impaired MSRs subsequently increases, management recognizes the increase in fair value in

current period mortgage banking income and, through a reduction in the valuation allowance, adjusts the carrying value of the MSRs to a level not in excess of amortized cost.

 

Reserve for Mortgage Loan Repurchase Losses–The Company sells mortgage loans to various third parties, including government-sponsored entities, under contractual provisions that include various representations and warranties that typically cover ownership of the loan, compliance with loan criteria set forth in the applicable agreement, validity of the lien securing the loan, absence of delinquent taxes or liens against the property securing the loan, and similar matters. The Company may be required to repurchase the mortgage loans with identified defects, indemnify the investor or insurer, or reimburse the investor for credit loss incurred on the loan (collectively “repurchase”) in the event of a material breach of such contractual representations or warranties. Risk associated with potential repurchases or other forms of settlement is managed through underwriting and quality assurance practices and by servicing mortgage loans to meet investor and secondary market standards.

 

The Company establishes mortgage repurchase reserves related to various representations and warranties that reflect management’s estimate of losses based on a combination of factors. Such factors incorporate actual and historic loss history, delinquency trends in the portfolio and economic conditions. The Company establishes a reserve at the time loans are sold and quarterly updates the reserve estimate during the estimated loan life. The repurchase reserve is included in other liabilities on the consolidated statements of financial condition.

 

Note 2 Recent Accounting Pronouncements

 

Revenue from Contracts with Customers—In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This update supersedes revenue recognition requirements in ASC Topic 605, Revenue Recognition, including most industry-specific revenue recognition guidance in the FASB Accounting Standards Codification. The new guidance stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides specific steps that entities should apply in order to achieve this principle. The amendments are effective for interim and annual periods beginning after December 15, 2017, with early application permitted for interim and annual periods beginning after December 15, 2016. ASU 2014-09 allows for either full retrospective or modified retrospective adoption.

 

The new guidance does not apply to revenue associated with financial assets and liabilities including loans, leases, securities, and derivatives that are accounted for under other GAAP. Accordingly, the majority of the Company’s revenues are not affected. The Company adopted ASU No. 2014-09 on January 1, 2018 utilizing the modified retrospective approach. Additionally, the Company has determined certain service charges, bank card fees and real estate sales are within the scope of the ASU, but has not identified changes to the timing or amount of revenue recognition. Accounting policies and procedures did not change materially as the principals of revenue recognition from the ASU are largely consistent with existing guidance and current practices applied by the Company. Refer to note 11 of our consolidated financial statements for required disclosures under the new standard.

 

Leases—In February 2016, the FASB issued ASU 2016-02, Leases. The guidance in ASU 2016-02 supersedes the lease recognition requirements in ASC Topic 840, Leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statements. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company expects to adopt ASU 2016-02 in the first quarter of 2019 and is currently in the process of evaluating the impact of the ASU's adoption on the Company's consolidated financial statements.  

 

Financial Instruments - Credit Losses—In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments. This update replaces the current incurred loss methodology for recognizing credit losses with a current expected credit loss model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This amendment broadens the information that an entity must consider in developing its expected credit loss estimates. Additionally, the update amends the accounting for credit losses for available-for-sale debt securities and purchased financial assets with a more-than-insignificant amount of credit deterioration since origination. This update requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of a company’s loan portfolio. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including

interim periods within those fiscal years. Early adoption in fiscal years beginning after December 15, 2018 is permitted. The amendment requires the use of the modified retrospective approach for adoption. The Company is in the process of evaluating the impact of the ASU’s adoption on the Company’s consolidated financial statements.

 

Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities—In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities. The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 is effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption is permitted, including in an interim period. ASU 2017-12 requires a modified retrospective transition method in which the Company will recognize the cumulative effect of the change on the opening balance of each affected component of equity in the consolidated statements of financial condition as of the date of adoption. The Company adopted ASU 2017-12 during the first quarter of 2018 and recorded a cumulative effect adjustment of $26 thousand within equity in the consolidated statements of financial condition.

 

Reclassification of Certain Tax Effects—In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This update allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The amendments eliminate the stranded tax effects that were created as a result of the reduction of historical U.S. federal corporate income tax rate to the newly enacted U.S. federal corporate income tax rate. The update is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company early adopted ASU 2018-02 in the first quarter of 2018, resulting in a $1.5 million reclassification from accumulated other comprehensive loss to retained earnings on the consolidated statements of financial condition and the consolidated statements of changes in shareholders’ equity.

 

The company adopted ASU 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825), ASU 2016-18, Restricted Cash (a consensus of the FASB Emerging Issues Task Force, ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments and ASU 2017-05 Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) with no material impact on its financial statements.

 

The Company reviewed ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, and does not expect the adoption of this pronouncement to have a material impact on its financial statements.

 

Note 3 Acquisition Activities

 

On January 1, 2018, the Company completed its acquisition of Peoples, Inc., the bank holding company of Colorado-based Peoples National Bank and Kansas-based Peoples Bank. Immediately following the completion of the acquisition, Peoples National Bank and Peoples Bank merged into NBH Bank. Pursuant to the merger agreement executed in June 2017, the Company paid $36.2 million of cash consideration and 3,398,477 shares of the Company’s Class A common stock in exchange for all of the outstanding common stock of Peoples. Included in the cash consideration is $10.0 million of restricted cash placed in escrow for certain potential liabilities the Company is indemnified for pursuant to the merger agreement. The restricted cash is included in other assets in the Company’s consolidated statements of financial condition at March 31, 2018. The transaction has a value of $146.4 million in the aggregate, based on the Company’s closing price of $32.43 on the acquisition date. Acquisition related costs of $7.6 million were included in the Company’s consolidated statements of operations for the three months ended March 31, 2018. The results of Peoples are included in the results of the Company subsequent to the acquisition date.

 

The Company determined that this acquisition constitutes a business combination as defined in ASC Topic 805, Business Combinations. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired and liabilities assumed at fair value. The Company determined fair values in accordance with the guidance provided in ASC Topic 820, Fair Value Measurements and Disclosures. Fair value is established by discounting the expected future cash flows with a market discount rate for like maturities and risk instruments. The estimation of expected future cash flows, market conditions and other future events and actual results could differ materially. The determination of the fair values of fixed assets, loans, OREO, core deposit intangible, mortgage servicing rights and mortgage repurchase reserve involves a high degree of judgment and complexity. The Company has made the determination of fair values using the best information available at the time; however, purchase accounting is not complete and the assumptions used are subject to change and, if changed, could have a material effect on the Company's financial position and results of operations.

 

The table below summarizes the net assets acquired (at fair value) and consideration transferred in connection with the Peoples acquisition:

 

 

In connection with the Peoples acquisition, the Company recorded $55.3 million of goodwill, a $10.5 million core deposit intangible asset, a $4.3 million mortgage servicing rights intangible asset and a $4.0 million mortgage repurchase reserve, included in other liabilities. The core deposit intangible will be amortized straight-line over ten years and the mortgage servicing rights intangible is amortized in proportion to and over the period of the estimated net servicing income. The FHLB borrowings of $33.9 million were paid off during the first quarter of 2018.

 

The fair value of the acquired assets and liabilities noted in the table may change during the provisional period, which may last up to twelve months subsequent to the acquisition date. The Company may obtain additional information to refine the valuation of the acquired assets and liabilities and adjust the recorded fair value. Adjustments recorded to the acquired assets and liabilities will be applied prospectively in accordance with ASU 2015-16.

 

At the date of acquisition, none of the loans were accounted for under the guidance of ASC Topic 310-30, and the gross contractual amounts receivable, inclusive of all principal and interest, was $713.6 million. The Company’s best estimate of the contractual cash flows for loans not expected to be collected was $6.1 million.

 

The following pro forma information combines the historical results of Peoples and the Company. The pro forma financial information does not include the potential impacts of possible business model changes, current market conditions, revenue enhancements, expense efficiencies, or other factors. If the Peoples acquisition had been completed on January 1, 2017, pro forma total revenue for the Company would have been approximately $65.5 million and $61.6 million for the three months ended March 31, 2018 and 2017, respectively. Pro forma net income for the Company would have been approximately $14.5 million and $9.9 million for the three month ended March 31, 2018 and 2017, respectively. Pro forma basic and dilutive earnings per share for the Company would have been $0.48 and $0.47 for the three months ended March 31, 2018, respectively, and $0.33 and $0.32 for the three months ended March 31, 2017, respectively. 

 

For the three months ended March 31, 2018, the pro forma information reflects adjustments made to exclude acquisition-related expenses of the Company of $7.6 million. For the three months ended March 31, 2017, the pro-forma information reflects adjustments made to include estimated amortization and accretion of purchase discounts and premiums of $0.2 million and estimated amortization of acquired identifiable intangibles of $0.3 million. The pro forma information is theoretical in nature and not necessarily indicative of future consolidated results of operations of the Company or the consolidated results of operations which would have resulted had the Company acquired Peoples during the periods presented.

 

The Company has determined that it is impractical to report the amounts of revenue and earnings of legacy Peoples since the acquisition date due to the integration of operations shortly after the acquisition date. Accordingly, reliable and separate complete revenue and earnings information is no longer available. In addition, such amounts would require significant estimates related to the proper allocation of merger cost savings that cannot be objectively made.

 

Note 4 Investment Securities

 

The Company’s investment securities portfolio is comprised of available-for-sale and held-to-maturity investment securities. These investment securities totaled $1.2 billion at March 31, 2018 and included $0.9 billion of available-for-sale securities and $0.3 billion of held-to-maturity securities. At December 31, 2017, investment securities totaled $1.1 billion and included $0.8 billion of available-for-sale securities and $0.3 billion of held-to-maturity securities.

 

Available-for-sale

 

At March 31, 2018 and December 31, 2017, the Company held $0.9 billion of available-for-sale investment securities. Available-for-sale securities are summarized as follows as of the dates indicated:

 

 

 

 

At March 31, 2018 and December 31, 2017, mortgage-backed securities represented primarily all of the Company’s available-for-sale investment portfolio and all mortgage-backed securities were backed by government sponsored enterprises (“GSE”) collateral such as Federal Home Loan Mortgage Corporation (“FHLMC”) and Federal National Mortgage Association (“FNMA”), and the government sponsored agency Government National Mortgage Association (“GNMA”).

 

The tables below summarize the available-for-sale securities with unrealized losses as of the dates shown, along with the length of the impairment period:

 

 

 

 

The unrealized losses in the Company's investment portfolio at March 31, 2018 were caused by changes in interest rates. The portfolio included 205 securities, having an aggregate fair value of $792.7 million, which were in an unrealized loss position at March 31, 2018, compared to 87 securities, with an aggregate fair value of $674.1 million at December 31, 2017.

 

Management evaluated all of the available for sale securities in an unrealized loss position at March 31, 2018 and December 31, 2017, and identified one municipal security with other-than-temporary impairment (OTTI), with an aggregate fair value of $0.3 million and $0.3 million, respectively. No OTTI charges were recorded during the three months ended March 31, 2018 and 2017. The unrealized losses on the remaining securities in an unrealized loss position were caused by changes in interest rates. The Company has no intention to sell these securities before recovery of their amortized cost and believes it will not be required to sell the securities before the recovery of their amortized cost.

 

Certain securities are pledged as collateral for public deposits, securities sold under agreements to repurchase, and to secure borrowing capacity at the Federal Reserve Bank and Federal Home Loan Bank (“FHLB”), if needed. The fair value of available-for-sale investment securities pledged as collateral totaled $427.8 million and $334.6 million at March 31, 2018 and December 31, 2017, respectively. Certain investment securities may also be pledged as collateral for the line of credit at the FHLB; at March 31, 2018 or December 31, 2017, no securities were pledged for this purpose.

 

Mortgage-backed securities do not have a single maturity date and actual maturities may differ from contractual maturities depending on the repayment characteristics and experience of the underlying financial instruments. The estimated weighted average life of the available-for-sale mortgage-backed securities portfolio was 3.5 years and 3.4 years at March 31, 2018 and December 31, 2017, respectively. This estimate is based on assumptions and actual results may differ. At March 31, 2018 and December 31, 2017, the duration of the total available-for-sale investment portfolio was 3.1 years and 3.1 years, respectively.

 

As of March 31, 2018, municipal securities with an amortized cost and fair value of $0.2 million were due after one year through five years, while municipal securities with an amortized cost and fair value of $0.5 million were due after five years through ten years. Other securities and municipal securities of $0.8 million as of March 31, 2018, have no stated contractual maturity date.
