The terms “we,” “our,” “us,” “the Company,” “CSTR” and “CapStar” that appear in this Quarterly Report on Form 10-Q (this “Report”) refer to CapStar Financial Holdings, Inc. and its wholly owned subsidiary, CapStar Bank.  The terms “CapStar Bank,” “the Bank” and “our Bank” that appear in this Report refer to CapStar Bank.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  These forward-looking statements reflect our current views with respect to, among other things, future events including, without limitation, the terms, timing and closing of the proposed mergers with Athens Bancshares Corporation and Athens Federal Community Bank (collectively, “Athens”) and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “should,” “could,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “anticipate,” “seek,” “aspire,” “roadmap,” “achieve,” “estimate,” “intend,” “plan,” “project,” “projection,” “forecast,” “goal,” “target,” “would,” and “outlook,” or the negative version of those words or other comparable words of a future or forward-looking nature. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. The inclusion of these forward-looking statements should not be regarded as a representation by us or any other person that such expectations, estimates and projections will be achieved. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date of this Report, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but not limited to, the following:

The acceptance by customers of Athens of the Company’s products and services; the ability of the Company to meet expectations regarding the benefits, costs, synergies, and financial and operational impact of the mergers with Athens Bancshares Corporation and Athens Federal Community Bank (collectively, “Athens”); the possibility that any of the anticipated benefits, costs, synergies and financial and operational improvements of the Athens merger will not be realized or will not be realized as expected; the possibility that the Athens merger integration may be more expensive or take more time to complete than anticipated; the opportunities to enhance market share in certain markets and market acceptance of the Company generally in new markets; economic conditions (including interest rate environment, government economic and monetary policies, the strength of global financial markets and inflation and deflation) that impact the financial services industry as a whole and/or our business; the concentration of our business in the Nashville metropolitan statistical area (“MSA”) and the effect of changes in the economic, political and environmental conditions on this market; increased competition in the financial services industry, locally, regionally or nationally, which may adversely affect pricing and the other terms offered to our clients; our dependence on our management team and board of directors and changes in our management and board composition; our reputation in the community; our ability to execute our strategy and to achieve our ROAA and efficiency ratio goals, hire seasoned bankers, loan and deposit growth through organic growth and strategic acquisitions; credit risks related to the size of our borrowers and our ability to adequately identify, assess and limit our credit risk; our concentration of large loans to a small number of borrowers; the significant portion of our loan portfolio that originated during the past two years and therefore may less reliably predict future collectability than older loans; the adequacy of reserves (including our allowance for loan losses) and the appropriateness of our methodology for calculating such reserves; non-performing loans and leases; non-performing assets; charge-offs, non-accruals, troubled-debt restructurings, impairments and other credit-related issues; adverse trends in the healthcare service industry, which is an integral component of our market’s economy; our management of risks inherent in our commercial real estate loan portfolio, and the risk of a prolonged downturn in the real estate market, which could impair the value of our collateral and our ability to sell collateral upon any foreclosure; governmental legislation and regulation, including changes in the nature and timing of the adoption and effectiveness of new requirements under the Dodd-Frank Act of 2010, as amended, the Tax Cuts and Jobs Act of 2017, Basel guidelines, capital requirements, accounting regulation or standards and other applicable laws and regulations; the loss of large depositor relationships, which could force us to fund our business through more expensive and less stable sources; operational and liquidity risks associated with our business, including liquidity risks inherent in correspondent banking; volatility in interest rates and our overall management of interest rate risk, including managing the sensitivity of our interest-earning assets and interest-bearing liabilities to interest rates, and the impact to our earnings from a change in interest rates; the potential for our Bank’s regulatory lending limits and other factors related to our size to restrict our growth and prevent us from effectively implementing our business strategy; strategic acquisitions we may undertake to achieve our goals; the sufficiency of our capital, including sources of capital and the extent to which we may be required to raise additional capital to meet our goals; fluctuations to the fair value of our investment securities that are beyond our control; deterioration in the fiscal position of the U.S. government and downgrades in Treasury and federal agency securities; potential exposure to fraud, negligence, computer theft and cyber-crime; the adequacy of our risk management framework; our dependence on our information technology and telecommunications systems and

3

the potential for any systems failures or interruptions; our dependence upon outside third parties for the processing and handling of our records and data; our ability to adapt to technological change; the financial soundness of other financial institutions; our exposure to environmental liability risk associated with our lending activities; our engagement in derivative transactions; our involvement from time to time in legal proceedings and examinations and remedial actions by regulators; the susceptibility of our market to natural disasters and acts of God; and the effectiveness of our internal controls over financial reporting and our ability to remediate any future material weakness in our internal controls over financial reporting.

The foregoing factors should not be construed as exhaustive and should be read in conjunction with those factors that are detailed from time to time in the Company’s periodic and current reports filed with the Securities and Exchange Commission (the “SEC”), including those factors included in the Company’s most recent Annual Report on Form 10-K under the heading “Item 1A. Risk Factors” and in the Company’s Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.  If one or more events related to these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may differ materially from our forward-looking statements. Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this Report, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for us to predict their occurrence or how they will affect us.

All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods presented have been included.  These unaudited consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and related notes appearing in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, determination of impairment of intangible assets, including goodwill, the valuation of our investment portfolio, deferred tax assets and estimated liabilities.  There have been no significant changes to the Company’s critical accounting policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Subsequent Events

Accounting Standards Codification (“ASC”) 855, Subsequent Events, establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. The Company evaluated all events or transactions that occurred after September 30, 2018 through the date of the issued financial statements.

Security fair values are established by an independent pricing service as of the dates indicated. The difference between amortized cost and fair value reflects current interest rates and represents the potential gain (loss) had the portfolio been liquidated on those dates. Security gains (losses) are realized only in the event of dispositions prior to maturity or other-than-temporary impairment. Securities with unrealized losses as of September 30, 2018 and December 31, 2017, and the length of time they were in continuous loss positions as of such dates are as follows (dollars in thousands):

As noted in the table above, as of September 30, 2018, the Company had unrealized losses of $7.1 million in its investment securities portfolio. The unrealized losses associated with these investment securities are driven by changes in interest rates and are recorded as a component of equity. These investment securities will continue to be monitored as a part of our ongoing impairment analysis. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments. If a shortfall in future cash flows is identified, a credit loss will be deemed to have occurred and will be recognized as a charge to earnings and a new cost basis for the security will be established.

Because the Company currently does not intend to sell any investment securities that have an unrealized loss at September 30, 2018, and it is not more-likely-than-not that we will be required to sell these investment securities before recovery of their amortized cost bases, which may be at maturity, we do not consider these securities to be other-than-temporarily impaired at September 30, 2018.

Securities with a market value of $148.7 million at September 30, 2018 were pledged to collateralize public deposits, derivative positions and Federal Home Loan Bank advances.

Results from sales of debt and equity securities were as follows (dollars in thousands):

	Nine Months Ended			Nine Months Ended

The amortized cost and fair value of securities at September 30, 2018, by contractual maturity, are shown below (dollars in thousands). Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

NOTE 3 – LOANS AND ALLOWANCE FOR LOAN LOSSES

A summary of the loan portfolio as of September 30, 2018 and December 31, 2017 follows (dollars in thousands):

	September 30, 2018			December 31, 2017
Commercial real estate	$	404,753		$	350,622
Consumer real estate		112,957			102,581
Construction and land development		129,799			82,586
Commercial and industrial		398,626			373,248
Consumer		8,274			6,862
Other		19,793			31,983
Total		1,074,202			947,882
Less net unearned income		(332	)		(345	)
Total loans		1,073,870			947,537
Allowance for loan losses		(15,218	)		(13,721	)
Total loans, net	$	1,058,652		$	933,816

The adequacy of the allowance for loan losses (ALL) is assessed at the end of each quarter. The ALL includes a specific component related to loans that are individually evaluated for impairment and a general component related to loans that are segregated into homogenous pools and collectively evaluated for impairment.  The ALL factors applied to these pools are an estimate of probable incurred losses based on management’s evaluation of historical net losses from loans with similar characteristics, which are adjusted by management to reflect current events, trends, and conditions. The adjustments include consideration of the following:  changes in lending policies and procedures, economic conditions, nature and volume of the portfolio, experience of lending management, volume and severity of past due loans, quality of the loan review system, value of underlying collateral for collateral dependent loans, concentrations, and other external factors.

12

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes all commercial loans, and consumer relationships with an outstanding balance greater than $500,000, individually and assigns each loan a risk rating. This analysis is performed on a continual basis by the relationship managers and credit department personnel. On at least an annual basis an independent party performs a formal credit risk review of a sample of the loan portfolio. Among other things, this review assesses the appropriateness of the loan’s risk rating. The Company uses the following definitions for risk ratings:

Special Mention – A special mention asset possesses deficiencies or potential weaknesses deserving of management’s attention. If uncorrected, such weaknesses or deficiencies may expose the Company to an increased risk of loss in the future.

Substandard – A substandard asset is inadequately protected by the current sound net 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 Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.

Doubtful – A doubtful asset has all weaknesses inherent in one classified substandard, with the added characteristic that weaknesses make collection or liquidation in full, on the basis of existing facts, conditions, and values, highly questionable and improbable. The probability of loss is extremely high, but certain important and reasonable specific pending factors which may work to the advantage and strengthening of the asset exist, therefore, its classification as an estimated loss is deferred until a more exact status may be determined. Pending factors include proposed merger, acquisition or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans.

Loans not falling into the criteria above are considered to be pass-rated loans. The Company utilizes six loan grades within the pass risk rating.

The following tables present the loan balances by category as well as risk rating (dollars in thousands):

As of September 30, 2018 and December 31, 2017, all loans classified as nonperforming were deemed to be impaired.

As of both September 30, 2018 and December 31, 2017, the Company had a recorded investment in TDR of $1.1 million. The Company had no specific allowance for those loans at September 30, 2018 or December 31, 2017 and there were no commitments to lend additional amounts.  Loans accounted for as TDR include modifications from original terms such as those due to bankruptcy proceedings, certain modifications of amortization periods or extended suspension of principal payments due to customer financial difficulties.  In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification.  This evaluation is performed under the Bank’s loan policy.  Loans accounted for as TDR are individually evaluated for impairment.

17

There were no TDR identified during the three or nine months ended September 30, 2018 or 2017.There were no TDR for which there was a payment default within twelve months following the modification during the three or nine months ended September 30, 2018 or 2017.

A loan is considered to be in payment default once it is 30 days contractually past due under the modified terms.

NOTE 4 – FEDERAL HOME LOAN BANK ADVANCES

The Company had outstanding borrowings totaling of $125.0 million and $70.0 million at September 30, 2018 and December 31, 2017, respectively, via various advances. These advances are non-callable; interest payments are due monthly, with principal due at maturity.

The following is a summary of the contractual maturities and average effective rates of outstanding advances (dollars in thousands):

NOTE 6 – INCOME TAXES

The Company’s effective tax rate for the three and nine months ended September 30, 2018 was 13.2% and 14.1% compared to 25.5% and 9.1% for the three and nine months ended September 30, 2017.  In March 2016, the FASB issued guidance to simplify several aspects of the accounting for share-based payment award transactions, including income tax consequences. In addition to other changes, the guidance changes the accounting for excess tax benefits and tax deficiencies from generally being recognized in additional paid-in capital to recognition as income tax expense or benefit in the period they occur. The Company adopted the new guidance in the first quarter of 2017. As a result, the Company’s income tax expense was reduced by $422,000 and $1,062,000 for the three and nine months ended September 30, 2018, respectively, and by $144,000 and $310,000 for the three and nine months ended September 30, 2017, respectively.

On December 22, 2017, Public Law 115-97, informally referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted into law. The Tax Reform Act provides for significant changes to the U.S. tax code that impact businesses. Effective January 1, 2018, the Tax Reform Act reduced the U.S. federal tax rate for corporations from 35% to 21% for U.S. taxable income.

The effective tax rate compared favorably to the statutory federal rate of 21% and Tennessee excise tax rate of 6.5% primarily due to investments in qualified municipal securities, company owned life insurance, state tax credits, net of the effect of certain non-deductible expenses and the recognition of excess tax benefits related to stock compensation.

NOTE 7 – COMMITMENTS AND CONTINGENCIES

In the normal course of business, the Company has outstanding commitments and contingent liabilities, such as commitments to extend credit and standby letters of credit, which are not included in the accompanying financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making such commitments as it does for instruments that are included in the balance sheet.

The following table sets forth outstanding financial instruments whose contract amounts represent credit risk as of September 30, 2018 and December 31, 2017 (dollars in thousands):

	Contract or notional amount
	September 30, 2018		December 31, 2017
Financial instruments whose contract amounts represent    credit risk:
Unused commitments to extend credit	$	622,212	$	584,494
Standby letters of credit		11,526		11,552
Total	$	633,738	$	596,046

19

The Company is party to litigation and claims arising in the normal course of business. Management believes that the liabilities, if any, arising from such litigation and claims as of September 30, 2018, will not have a material impact on the financial statements of the Company.

NOTE 8 – DERIVATIVES

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.

Interest Rate Swaps Designated as Cash Flow Hedges

Forward starting interest rate swaps with notional amounts totaling $20 million as of September 30, 2018 and December 31, 2017 were designated as cash flow hedges of certain liabilities and were determined to be fully effective during all periods presented. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets (liabilities) with changes in fair value recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Company expects the hedges to remain fully effective during the remaining terms of the swaps.

Summary information about the interest-rate swaps designated as cash flow hedges was as follows (dollars in thousands):

	September 30, 2018			December 31, 2017
Notional amounts	$	20,000		$	20,000

Fair value	$	(462	)	$	(1,375	)
Amount of unrealized loss recognized in accumulated    other comprehensive income, net of tax	$	(341	)	$	(1,016	)

Pursuant to its interest rate swap agreements, the Company pledged collateral to the counterparties in the form of investment securities with a market value of $2.1 million at September 30, 2018. There was no collateral posted from the counterparties to the Company as of September 30, 2018. It is possible that the Company may need to post additional collateral in the future or that the counterparties may be required to post collateral to the Company in the future.

Other Interest Rate Swaps

The Company also enters into swaps to facilitate customer transactions and meet their financing needs.  Upon entering into these transactions the Company enters into offsetting positions with large U.S. financial institutions in order to minimize risk to the Company. A summary of the Company’s customer related interest rate swaps was as follows (dollars in thousands):

NOTE 9 - STOCK OPTIONS AND RESTRICTED SHARES

During 2008, the board of directors of the Bank approved the CapStar Bank 2008 Stock Incentive Plan. Following the formation of CapStar Financial Holdings, Inc. in 2016, and in connection with the Share Exchange, the outstanding awards of restricted stock and stock options under the CapStar Bank 2008 Stock Incentive Plan were exchanged for similar awards of restricted stock and stock options issued by CapStar Financial Holdings, Inc. under the CapStar Financial Holdings, Inc. Stock Incentive Plan (the “Plan”), which the board of directors adopted in 2016. The Stock Incentive Plan provides for the grant of stock-based incentives, including

20

stock options, restricted stock units, performance awards and restricted stock, to employees, directors and service providers that are subject to forfeiture until vesting conditions have been satisfied by the award recipient under the terms of the award.  The Plan is intended to help align the interests of employees and our shareholders and reward our employees for improved Company performance.  The Plan reserved 1,569,475 shares of stock for issuance of stock incentives. In April 2018 the board of directors reserved an additional 400,000 shares of stock for issuance of stock incentives.  Stock incentives include both restricted share and stock option grants.  Total shares issuable under the plan were 506,435 at September 30, 2018.

The Company has recognized stock-based compensation expense, within salaries and employee benefits for employees, and within other non-interest expense for directors, in the consolidated statements of income as follows (dollars in thousands):

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2018			2017			2018			2017
Stock-based compensation expense before income taxes	$	310		$	288		$	940		$	771
Less: deferred tax benefit		(81	)		(110	)		(246	)		(295	)
Reduction of net income	$	229		$	178		$	694		$	476

Restricted Shares

Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at the issue date. The fair value of each restricted stock grant is based on valuations performed by independent consultants. The recipients have the right to vote and receive dividends but cannot sell, transfer, assign, pledge, hypothecate, or otherwise encumber the restricted stock until the shares have vested. Restricted shares fully vest on the third anniversary of the grant date.  A summary of the changes in the Company’s nonvested restricted shares for the nine months ended September 30, 2018 follows:

				Weighted
				Average
	Restricted			Grant Date
Nonvested Shares	Shares			Fair Value
Nonvested at beginning of period		187,253		$	14.21
Granted		53,869			19.11
Vested		(99,603	)		12.61
Forfeited		(8,065	)		15.95
Nonvested at end of period		133,454		$	17.28

As of September 30, 2018, there was $1.6 million of unrecognized compensation cost related to nonvested shares granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 2.0 years.  The total fair value of shares vested during the nine months ended September 30, 2018 and 2017 was $1.9 million and $1.1 million.

Stock Options

Option awards are generally granted with an exercise price equal to the fair value of the Company’s common stock at the date of grant.  Option awards generally have a four year vesting period and a ten year contractual term.

The fair value of each option grant is estimated on the date of grant using the Black Scholes option pricing model. There were no options granted in 2018 or 2017.

As of September 30, 2018, there was $0.1 million of unrecognized compensation cost related to nonvested stock options granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 1.0 year.

NOTE 10 – REGULATORY CAPITAL REQUIREMENTS

The Company and the Bank are subject to regulatory capital requirements administered by the Federal Reserve and the Bank is also subject to the regulatory capital requirements of the Tennessee Department of Financial Institutions. Failure to meet capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that could, in that event, have a material adverse effect on the institutions’ financial statements. The relevant regulations require the Company and the Bank to meet specific capital adequacy guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting principles. The capital classifications of the Company and the Bank are also subject to qualitative judgments by their regulators about components, risk weightings, and other factors. Those qualitative judgments could also affect the capital status of the Company and the Bank and the amount of dividends the Company and the Bank may distribute. The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Bank on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of September 30, 2018, the Company and the Bank met all regulatory capital adequacy requirements to which they are subject.

22

The Company’s and the Bank’s capital amounts and ratios as of September 30, 2018 and December 31, 2017 are presented in the following table (dollars in thousands).

NOTE 12 – FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Bank used the following methods and significant assumptions to estimate fair value:

Investment Securities: The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded and, values debt securities by relying on quoted prices for the specific securities and the securities’ relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). See below for additional discussion of Level 3 valuation methodologies and significant inputs. The fair values of all securities are determined from third party pricing services without adjustment.

Derivatives-Interest Rate Swaps: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Bank’s derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.  The fair values of all interest rate swaps are determined from third party pricing services without adjustment.

24

Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on at least a quarterly basis for additional impairment and adjusted in accordance with the loan policy.

Other Real Estate Owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Appraisals may be adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and/or management’s expertise and knowledge of the collateral. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly.  The Company had no other real estate owned at September 30, 2018 or December 31, 2017.

Loans Held For Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2).  There were no loans held for sale carried at fair value at September 30, 2018 or December 31, 2017.

The methods and assumptions, not previously presented, used to estimate fair values are described as follows:

(a) Cash and Due from Banks, Interest-Bearing Deposits in Financial Institutions

For these short‑term instruments, the carrying amount is a reasonable estimate of fair value.

(b) Federal Funds Sold

Federal funds sold clear on a daily basis. For this reason, the carrying amount is a reasonable estimate of fair value.

(c) Restricted Equity Securities

It is not practical to determine the fair value of restricted securities due to restrictions placed on their transferability.

(d) Loans, net

During the first quarter of 2018, the Company adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.”  The amendments included within this standard, which are applied prospectively, require the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using an exit price notion.  Prior to adopting the amendments included in the standard, the Company was allowed to measure fair value under an entry price notion.  The entry price notion previously applied by the Company used a discounted cash flows technique to calculate the present value of expected future cash flows for a financial instrument.  The exit price notion uses the same approach, but also incorporates other factors, such as enhanced credit risk, illiquidity risk and market factors that sometimes exist in exit prices in dislocated markets.  

27

As of September 30, 2018, the technique used by the Company to estimate the exit price of the loan portfolio consists of similar procedures to those used as of December 31, 2017, but with added emphasis on both illiquidity risk and credit risk not captured by the previously applied entry price notion. The fair value of the Company’s loan portfolio has always included a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk as described above.  However, under the new guidance, the Company believes a further credit risk discount must be applied through the use of a discounted cash flow model to compensate for illiquidity risk, based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of enhanced credit risk provides an estimated exit price for the Company’s loan portfolio.

For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral.

As of December 31, 2017, the fair value of the Company’s loan portfolio includes a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral. For other loans, fair values are estimated using discounted cash flow models, using current market interest rates offered for loans with similar terms to borrowers of similar credit quality. The values derived from the discounted cash flow approach for each of the above portfolios are then further discounted to incorporate credit risk. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price as of December 31, 2017.

(e) Accrued Interest Receivable

The carrying amounts of accrued interest approximate fair value.

(f) Other Assets

Included in other assets are bank owned life insurance, certain interest rate swap agreements and the cash flow hedge relationships. The fair values of interest rate swap agreements and the cash flow hedge relationships are based on independent pricing services that utilize pricing models with observable market inputs. For bank owned life insurance, the carrying amount is based on the cash surrender value and is a reasonable estimate of fair value.

(g) Deposits

The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of certificates of deposit is estimated by discounted cash flow models, using current market interest rates offered on certificates with similar remaining maturities.

(h) Federal Home Loan Bank Advances

The fair value of fixed rate Federal Home Loan Bank Advances is estimated using discounted cash flow models, using current market interest rates offered on certificates, advances and other borrowings with similar remaining maturities.

(i) Other Liabilities

Included in other liabilities are accrued interest payable, certain interest rate swap agreements, the cash flow hedge relationships and contingent consideration. The fair values of interest rate swap agreements and the cash flow hedge relationships are based on independent pricing services that utilize pricing models with observable market inputs.  The fair value of contingent consideration is estimated by a discounted cash flow model that utilizes various unobservable inputs.  The carrying amounts of accrued interest approximate fair value.

(j) Off-Balance Sheet Instruments

Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.  The fair value of commitments is not material.

28

(k) Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on estimating on and off‑balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, fixed assets are not considered financial instruments and their value has not been incorporated into the fair value estimates. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

NOTE 13 – SUBSEQUENT EVENT

On October 1, 2018, pursuant to the Agreement and Plan of Merger, dated as of June 11, 2018 (the “Merger Agreement”), by and between CapStar Financial Holdings, Inc., a Tennessee corporation (“CapStar”), and Athens Bancshares Corporation, a Tennessee corporation (“Athens”), Athens was merged with and into CapStar, with CapStar continuing as the surviving entity (the “Merger”). Immediately following the Merger, Athens Federal Community Bank, National Association, a wholly owned subsidiary of Athens, merged with and into CapStar Bank, a wholly owned subsidiary of CapStar (the “Bank Merger”), with CapStar Bank continuing as the surviving entity in the Bank Merger.

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01, of Athens (“Athens Common Stock”) issued and outstanding immediately prior to the completion of the merger (other than dissenting shares and shares of Athens common stock owned directly or indirectly by Athens, CapStar and their wholly owned subsidiaries (in each case, other than shares of Athens common stock held in a fiduciary capacity or in connection with debts previously contracted) was converted into the right to receive 2.864 shares (the “Exchange Ratio”) of voting common stock, par value $1.00 per share, of CapStar (“CapStar Common Stock”), with cash paid in lieu of fractional shares. This resulted in the issuance of 5,181,916 shares of CapStar common stock on October 1, 2018.

At the Effective Time, each outstanding and unexercised Athens stock option granted under the Athens Bancshares Corporation 2010 Equity Incentive Plan (the “Athens Equity Plan”) that was held by an employee or service provider of Athens who had terminated service prior to the Effective Time was cancelled and converted into the right to receive the cash value of the merger consideration (determined in accordance with the terms of the Merger Agreement), less the applicable option exercise price and less applicable withholding taxes. Except as described in the prior sentence, each outstanding and unexercised Athens stock option granted under the Athens Equity Plan was converted into an option to purchase shares of CapStar Common Stock, with the number of shares and exercise price adjusted to reflect the Exchange Ratio in accordance with the terms of the Merger Agreement. The converted options resulted in the right to purchase 548,051 shares of CapStar Common Stock at a weighted average exercise price of $5.06.

Total acquisition consideration resulting from the Merger amounted to approximately $92.9 million.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which was attached as Exhibit 2.1 to CapStar’s Form 8-K filed with the U.S. Securities and Exchange Commission on June 14, 2018 and the terms of which are incorporated herein by reference.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following is a discussion of our financial condition at September 30, 2018 and December 31, 2017 and our results of operations for the three and nine months ended September 30, 2018 and 2017.  The purpose of this discussion is to focus on information about our financial condition and results of operations which is not otherwise apparent from the consolidated financial statements.  The following discussion and analysis should be read along with our consolidated financial statements and the related notes included elsewhere in this Report and our Annual Report on Form 10-K for the year ended December 31, 2017.  Annualized results for interim periods may not be indicative of results for the full year or future periods.  In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from our current expectations.  Factors that could cause such differences are discussed in the section entitled “Cautionary Note Regarding Forward-Looking Statements” in this Report and the section entitled “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2017. We assume no obligation to update any of these forward-looking statements except to the extent required by applicable law.

The following discussion and analysis pertains to our historical results on a consolidated basis.  However, because we conduct all of our material business operations through our wholly owned subsidiary, CapStar Bank, the following discussion and analysis relates to activities primarily conducted at the subsidiary level.

All dollar amounts in the tables in this section are in thousands of dollars, except per share data or when otherwise specifically noted.

Overview

Our diluted net income per share of common stock for the three and nine months ended September 30, 2018 was $0.28 and $0.79, respectively, compared to $0.35 and $0.11, respectively, for the three and nine months ended September 30, 2017.  The increase in our net income for the nine months ended September 30, 2018 compared to the same period in 2017 was primarily due to decreased loan charge-offs and the resulting provision for loan losses.  During the nine months ended September 30, 2018 and 2017, loan charge-offs amounted to $0.3 million and $12.4 million, respectively. At September 30, 2018, loans increased to $1.07 billion, as compared to $0.95 billion at December 31, 2017.  Total deposits increased to $1.13 billion at September 30, 2018 from $1.12 billion at December 31, 2017.

On October 1, 2018, the Company and Athens Bancshares Corporation (“Athens”), the bank holding company for Athens Federal Community Bank, National Association (“Athens Federal”), located in Athens, Tennessee, completed a merger pursuant to which Athens merged with and into CapStar and Athens Federal merged with and into CapStar Bank.  We incurred merger related expenses in connection with this transaction amounting to $0.5 million and $0.9 million during the three and nine months ended September 30, 2018.  No merger related expenses were incurred during the three and nine months ended September 30, 2017.

The Company’s primary revenue sources are net interest income and fees from various financial services provided to customers. Net interest income is the difference between interest income earned on loans, investment securities and other interest earning assets less interest expense on deposit accounts and other interest bearing liabilities. Loan volume and interest rates earned on those loans are critical to our overall profitability. Similarly, deposit volume is crucial to funding loans, and rates paid on deposits directly impact our profitability. Business volumes are influenced by competition, new business acquisition efforts and economic factors including market interest rates, business spending and consumer confidence.

Net interest income increased $0.7 million, or 6.5%, for the three months ended September 30, 2018 compared to the same period in 2017 and increased $2.6 million, or 8.4%, for the nine months ended September 30, 2018 compared to the same period in 2017.  The positive effects of increased yields on earning assets were partially offset by the negative effect of increasing deposit costs. Net interest margin increased to 3.35% for the three months ended September 30, 2018, compared with 3.31% for the same period of 2017 and increased to 3.40% for the nine months ended September 30, 2018, compared with 3.23% for the same period of 2017.

In response to the assessment of risk in the loan portfolio, including net loan growth and charge-offs, we recorded a $0.5 million and $1.3 million provision for loan losses, respectively, for the three and nine months ended September 30, 2018 compared to $(0.2) million and $12.9 million, respectively, for the three and nine months ended September 30, 2017. The 2017 provision for loan losses was caused primarily by deterioration in the credit quality of commercial and industrial loans to one borrower.  The provision for loan losses represents a charge to earnings necessary to establish an allowance for loan losses that, in management’s evaluation, is adequate to provide coverage for the estimated probable inherent losses on outstanding loans.  Our allowance for loan losses at September 30, 2018 was 1.42% of total loans, compared with 1.45% of total loans at December 31, 2017.

30

Total non-interest income for the three months ended September 30, 2018 decreased $0.2 million, or 4.6%, compared with the same period in 2017, and comprised 17% of total revenues.  For the nine months ended September 30, 2018, total non-interest income increased $0.9 million, or 11.0%, compared with the same period in 2017, and comprised 17% of total revenues.  These increases were primarily the result of higher Tri-Net fees related to increased volumes of commercial real estate loan sales.

As we grew our team and expanded in the Nashville MSA, total non-interest expense for the three and nine months ended September 30, 2018 increased $1.6 million, or 18.8%, and $4.6 million, or 18.3%, respectively, compared with the same periods in 2017. Our efficiency ratio for the three months ended September 30, 2018 was 68.2% compared to 59.6% for the same period in 2017.  For the nine months ended September 30, 2018 our efficiency ratio was 68.9% compared to 63.4% for the same period in 2017.  The increases in our efficiency ratio are a reflection of our investment in new employees, increased incentive compensation consistent with the Company’s overall performance, and the addition of merger related expenses resulting from our merger with Athens.

Our effective tax rate for the three and nine months ended September 30, 2018 was 13.2% and 14.1%, respectively, compared to 25.5% and 9.1% for the same periods in 2017.  The changes in the effective tax rate are largely the result of the ratio of excess tax benefits from stock compensation to income before income taxes.

Tangible common equity (“TCE”), a non-GAAP measure, is a measure of a company's capital which is useful in evaluating the quality and adequacy of capital. The ratio of tangible common equity to total tangible assets was 10.1% as of September 30, 2018, compared with 9.8% at December 31, 2017.  See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Non-GAAP Financial Measures” for details on reconciliations to the most directly comparable U.S. GAAP measures.

The following sections provide more details on subjects presented in this overview.

Net Interest Income

The largest component of our net income is net interest income – the difference between the income earned on interest-earning assets and the interest paid on deposits and borrowed funds used to support our assets. Net interest income divided by total average interest-earning assets represents our net interest margin. The major factors that affect net interest income and net interest margin are changes in volumes, the yield on interest-earning assets and the cost of interest-bearing liabilities. Our margin can also be affected by economic conditions, the competitive environment, loan demand and deposit flow. Our ability to respond to changes in these factors by using effective asset-liability management techniques is critical to maintaining the stability of the net interest margin and our net interest income.

The following tables set forth the amount of our average balances, interest income or interest expense for each category of interest-earning assets and interest-bearing liabilities and the average interest rate for interest-earning assets and interest-bearing liabilities, net interest spread and net interest margin for the three and nine months ended September 30, 2018 and 2017:

Our net interest margin was 3.35% and 3.31% for the third quarter of 2018 and 2017, respectively.  For the nine months ended September 30, 2018 and 2017, our net interest margin was 3.40% and 3.23%, respectively.  The increase in net interest margin for both periods was primarily due to rising yields on earning assets offset by rising deposit costs.  From December 31, 2016 to September 30, 2018, the LIBOR – 1 month interest rate increased from 0.72% to 2.27%.  Approximately 65% of our loan portfolio is variable in nature.

For the third quarter of 2018 and 2017, average loan yields increased from 4.55% to 5.00% which was primarily driven by increases in short-term interest rate indexes affecting the variable rate portion of our loan portfolio, offset by competitive pricing pressures.  For the nine months ended September 30, 2018 and 2017, average loan yields increased from 4.36% to 4.93%.

For the third quarter of 2017 and 2018, average security yields increased from 2.72% to 2.85% and from 2.71% to 2.78% for the nine months ended September 30, 2017 and 2018, respectively, primarily due to increases in the LIBOR rate on the variable rate portion of our securities portfolio.  

33

The resulting yield on average interest-earning assets increased 46 basis points for the third quarter of 2018 compared to the similar period in 2017 and 53 basis points for the nine months ended September 30, 2018 compared to the similar period of 2017.

The average rate paid on interest-bearing liabilities was 1.64% for the third quarter of 2018, as compared to 1.08% for the same period in 2017. For the nine months ended September 30, 2018 and 2017, the average rate paid on interest-bearing liabilities was 1.48% and 0.95%, respectively.  These increases were due to the increases in the Fed Funds rate which increased from 0.75% at December 31, 2016 to 2.25% at September 30, 2018. We passed along a portion of these rate increases to our clients.

Asset/Liability Management and Interest Rate Risk

Managing interest rate risk is fundamental for the financial services industry. By considering both on and off-balance sheet financial instruments, management evaluates interest rate sensitivity while attempting to optimize net interest income within the constraints of prudent capital adequacy, liquidity needs, market opportunities and customer requirements.

Interest Rate Simulation Sensitivity Analysis

We use earnings at risk, or EAR, simulations to assess the impact of changing rates on earnings under a variety of scenarios and time horizons. The simulation model is designed to reflect the dynamics of interest earning assets, interest bearing liabilities and off-balance sheet financial instruments.  These simulations utilize both instantaneous and parallel changes in the level of interest rates, as well as non-parallel changes such as changing slopes and twists of the yield curve.  Static simulation models are based on current exposures and assume a constant balance sheet with no new growth.  Dynamic simulation models are also utilized that rely on detailed assumptions regarding changes in existing lines of business, new business, and changes in management and client behavior.  By estimating the effects of interest rate increases and decreases, the model can reveal approximate interest rate risk exposure. The simulation model is used by management to gauge approximate results given a specific change in interest rates at a given point in time. The model is therefore a tool to indicate earnings trends in given interest rate scenarios and does not indicate actual expected results.

At September 30, 2018, our EAR static simulation results indicated that our balance sheet is asset sensitive to parallel shifts in interest rates. This indicates that our assets generally reprice faster than our liabilities, which results in a favorable impact to net interest income when market interest rates increase. Many assumptions are used to calculate the impact of interest rate fluctuations on our net interest income, such as asset prepayments, non-maturity deposit price sensitivity and decay rates, and key rate drivers. Because of the inherent use of these estimates and assumptions in the model, our actual results may, and most likely will, differ from our static EAR results. In addition, static EAR results do not include actions that our management may undertake to manage the risks in response to anticipated changes in interest rates or client behavior. For example, as part of our asset/liability management strategy, management has the ability to increase asset duration and/or decrease liability duration in order to reduce asset sensitivity, or to decrease asset duration and/or increase liability duration in order to increase asset sensitivity. 

The following table illustrates the results of our EAR analysis to determine the extent to which our net interest income over the next 12 months would change if prevailing interest rates increased or decreased by the specified amounts.

	Net interest income change
Increase 200bp		2.7%
Increase 100bp		1.4
Decrease 100bp		(3.7)
Decrease 200bp		(15.3)

Provision for Loan Losses

Our policy is to maintain an allowance for loan losses at a level sufficient to absorb probable incurred losses inherent in the loan portfolio. The allowance is increased by a provision for loan losses, which is a charge to earnings, is decreased by charge-offs and is increased by loan recoveries. Our allowance for loan losses as a percentage of total loans was 1.42% and 1.45% at September 30, 2018 and December 31, 2017, respectively.

34

The provision for loan losses amounted to $0.5 million and $1.3 million, respectively, for the three and ninemonths ended September 30, 2018 compared to $(0.2)million and $12.9million, respectively, for the three and nine months ended September 30, 2017. Provision expense is impacted by the absolute level of loans, loan growth, the credit quality of the loan portfolio and the amount of net charge-offs.

Provision expense increased for the three months ended September 30, 2018 compared to the comparable period in 2017 primarily due to increased loan growth.  Provision expense decreased for the nine months ended September 30, 2018 compared to the comparable period in 2017 due to decreased charge-offs.  Charge-offs for the nine months ended September 30, 2018 were $0.3 million compared to $12.4 million for the nine months ended September 30, 2017.  

Based upon our evaluation of the loan portfolio, we believe the allowance for loan losses to be appropriate to absorb our estimate of probable losses existing in the loan portfolio at September 30, 2018. While our policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to operations, are considered adequate by management, they are necessarily approximate and imprecise. There are factors beyond our control, such as conditions in the local and national economy, local real estate markets, or particular industry or borrower-specific conditions, which may materially negatively impact our asset quality and the adequacy of our allowance for loan losses and, thus, the resulting provision for loan losses.  See “Notes to Consolidated Financial Statements (Unaudited) — Note 3 — Loans and Allowance for Loan Losses” for additional information on our allowance for loan losses.

Noninterest Income

In addition to net interest income, we generate other types of recurring noninterest income from our lines of business. Our banking operations generate revenue from service charges and fees on deposit accounts. We have a mortgage banking line of business that generates revenue from originating and selling mortgages, a line of business that originates and sells commercial real estate loans (Tri-Net), and we have a revenue-sharing relationship with a registered broker-dealer, which generates wealth management fees. In addition to these types of recurring noninterest income, we own insurance on several key employees and record income on the increase in the cash surrender value of these policies.

The following table sets forth the principal components of noninterest income for the periods indicated.

						2018-2017							2018-2017
	Three Months Ended					Percent			Nine Months Ended				Percent
	September 30,					Increase			September 30,				Increase
	2018			2017		(Decrease)			2018		2017		(Decrease)
Noninterest income:
Treasury management and other deposit service charges	$	528		$	427		23.8	%	$	1,357	$	1,097		23.7	%
Net gain (loss) on sale of securities		(1	)		9		(110.0	)%		2		42		(95.0	)%
Tri-Net fees		373			367		2.0	%		1,227		748		64.0	%
Mortgage banking income		1,634			2,030		(19.5	)%		4,329		4,617		(6.2	)%
Other noninterest income		684			539		26.5	%		2,157		1,667		29.3	%
Total noninterest income	$	3,218		$	3,372		(4.6	)%	$	9,072	$	8,171		11.0	%

The increase in treasury management and other deposit service charges for the three and nine months ended September 30, 2018 compared to the same periods in 2017 is driven primarily by transaction volume, which can fluctuate from period to period.  

Tri-Net fees represent a line of business, implemented in the fourth quarter of 2016, which originates and sells commercial real estate loans to third-party investors.  All of these loan sales transfer servicing rights to the buyer.  The volume of loan sales has increased since this new line of business was implemented.

Mortgage banking income consists of mortgage fee income from the origination and sale of mortgage loans.  These mortgage fees are for loans that we originated and that are subsequently sold to third-party investors.  All of these loan sales transfer servicing rights to the buyer. Mortgage origination fees will fluctuate from quarter to quarter as the interest rate environment changes and due to the timing of loan sales.

Other noninterest income consists of various revenue streams.  The increase in other noninterest income for the three and nine months ended September 30, 2018 compared to the same periods in 2017 is primarily due to increases in one-time, transaction related loan fees.

35

Noninterest Expense

Our total noninterest expense increase reflects expenses that we have incurred as we build the foundation to support our recent growth and enable us to execute our growth strategy. The following table presents the primary components of noninterest expense for the periods indicated.

					2018-2017							2018-2017
	Three Months Ended				Percent			Nine Months Ended				Percent
	September 30,				Increase			September 30,				Increase
	2018		2017		(Decrease)			2018		2017		(Decrease)
Noninterest expense:
Salaries and employee benefits	$	6,514	$	5,119		27.2	%	$	19,111	$	14,989		27.5	%
Data processing and software		803		709		13.3	%		2,411		2,040		18.2	%
Professional fees		255		336		(23.9	)%		1,074		1,050		2.3	%
Occupancy		544		531		2.5	%		1,600		1,518		5.4	%
Equipment		520		564		(7.8	)%		1,661		1,604		3.6	%
Regulatory fees		228		270		(15.3	)%		664		877		(24.3	)%
Merger related expenses		540		—		100.0	%		875		—		100.0	%
Other operating		666		946		(22.4	)%		2,259		2,988		(22.1	)%
Total noninterest expense	$	10,070	$	8,475		18.8	%	$	29,655	$	25,066		18.3	%

Salaries and employee benefits increased 27.2% and 27.5%, respectively, for the three and nine months ended September 30, 2018 compared to the similar periods in 2017. The increase is primarily related to increased incentive expense related to improved financial performance and the addition of personnel associated with continued expansion in the Nashville MSA. The number of full-time employees increased from 170 at January 1, 2017 to 185 at September 30, 2018.

Data processing and software expense increased during the periods presented due to an increase in the volume of transactions and implementation of new software in our mortgage banking line of business.

Merger related expenses during the three and nine months ended September 30, 2018 are the result of our recently completed merger with Athens.  Merger related expenses are expected to approximate $11.5 million in total over the course of the acquisition.

Other operating expense declined for the three and nine months ended September 30, 2018 compared to the similar periods in 2017 primarily because of one-time costs incurred in 2017 related to the move of our corporate headquarters and expenses related to the loans charged off in the second quarter of 2017.

Our efficiency ratio (ratio of noninterest expense to the sum of net interest income and noninterest income) was 68.2% for the three months ended September 30, 2018 compared to 59.6% for the same period 2017.  For the nine months ended September 30, 2018 and 2017, our efficiency ratio was 68.9% and 63.4%, respectively. The efficiency ratio for both periods was negatively impacted by growth in our expenses that outpaced increases in our revenues.  The increases in our efficiency ratio are a reflection of our investment in new employees, increased incentive compensation consistent with the Company’s overall performance, and the addition of merger related expenses resulting from our merger with Athens. The efficiency ratio measures the amount of expense that is incurred to generate a dollar of revenue. For the nine months ended September 30, 2018, our revenue base (net interest income plus noninterest income) grew at a rate of approximately 0.5 times our noninterest expense.

36

Income Tax Provision

During the three and nine months ended September 30, 2018, we recorded income tax expense of $0.6 million and $1.7 million, respectively, compared to $1.5 million and $0.1 million, respectively, for the three and nine months ended September 30, 2017. Our income tax expense for the nine months ended September 30, 2018 reflects an effective income tax rate of 14.1% compared to 9.1% for the same period in 2017.  Our effective tax rate differs from the statutory tax rate by our investments in municipal securities, company owned life insurance, state tax credits, net of the effect of certain non-deductible expenses and the recognition of excess tax benefits related to stock compensation.  

In March 2016, the FASB issued guidance to simplify several aspects of the accounting for share-based payment award transactions, including income tax consequences. In addition to other changes, the guidance changes the accounting for excess tax benefits and tax deficiencies from generally being recognized in additional paid-in capital to recognition as income tax expense or benefit in the period they occur. The Company adopted the new guidance in the first quarter of 2017. As a result, the Company’s income tax expense was reduced by $422,000 and $1,062,000 for the three and nine months ended September 30, 2018, respectively, and by $144,000 and $310,000 for the three and nine months ended September 30, 2017, respectively.

(b) Financial Condition

Balance Sheet

Total assets increased $72.5 million, or 5.4%, from $1.34 billion at December 31, 2017 to $1.42 billion at September 30, 2018. Loans grew $126.3 million, or 13.3%, in the first nine months of 2018, offset by a decrease in cash of $30.2 million, or 36.5%, for the same period. Loans held for sale decreased $23.6 million, or 31.8%, during the first nine months of 2018.  

Total liabilities increased $62.0 million, or 5.2%, from $1.20 billion at December 31, 2017 to $1.26 billion at September 30, 2018. Deposits increased $6.5 million, or 0.6%, over the same period of time.  We increased our Federal Home Loan Bank advances $55.0 million during the first nine months of 2018 to help fund our loan growth.

Loans and Leases

The composition of loans and leases at September 30, 2018 and December 31, 2017 and the percentage of each classification to total loans are summarized as follows:

	September 30, 2018					December 31, 2017
	Amount		Percent			Amount		Percent
Commercial real estate - owner occupied	$	117,904		11.0	%	$	101,132		10.7	%
Commercial real estate - non-owner occupied		286,849		26.7	%		249,490		26.3	%
Consumer real estate		112,957		10.5	%		102,581		10.8	%
Construction and land development		129,799		12.1	%		82,586		8.7	%
Commercial and industrial		398,626		37.1	%		373,248		39.4	%
Consumer		8,274		0.8	%		6,862		0.7	%
Other		19,793		1.8	%		31,983		3.4	%
Total loans	$	1,074,202		100.0	%	$	947,882		100.0	%

At September 30, 2018, our loan portfolio composition remained relatively consistent with the composition at December 31, 2017. The commercial real estate owner-occupied category contains loans which are similar in many ways to our commercial and industrial lending in that these loans are generally made to businesses on the basis of the cash flows of the business rather than on the valuation of the real estate.

(c) Liquidity

Liquidity risk is the risk that we will be unable to meet our obligations as they become due because of an inability to liquidate assets or obtain adequate funding.  To manage liquidity risk, management has established a comprehensive management process for identifying, measuring, monitoring and controlling liquidity risk.  Because of its critical importance to the viability of the Bank, liquidity risk management is fully integrated into our risk management processes. Critical elements of our liquidity risk management include: effective corporate governance consisting of oversight by the board of directors and active involvement by management; appropriate strategies, policies, procedures, and limits used to manage and mitigate liquidity risk; comprehensive liquidity risk measurement and monitoring systems (including assessments of the current and prospective cash flows or sources and uses of funds) that are commensurate with the complexity and business activities of the Bank; active management of intraday liquidity and collateral; an appropriately diverse mix of existing and potential future funding sources; adequate levels of highly liquid marketable securities free of legal, regulatory, or operational impediments, that can be used to meet liquidity needs in stressful situations; comprehensive contingency funding plans that sufficiently address potential adverse liquidity events and emergency cash flow requirements; and internal controls and internal audit processes sufficient to determine the adequacy of the institution’s liquidity risk management process.

The role of liquidity management is to ensure funds are available to meet depositors’ withdrawal and borrowers’ credit demands while at the same time maximizing financial results. This is accomplished by balancing changes in demand for funds with changes in the supply of those funds. Liquidity is provided by short-term liquid assets that can be converted to cash, investment securities available-for-sale, various lines of credit available to us, and the ability to attract funds from external sources, principally deposits.

Our most liquid assets are comprised of cash and due from banks, available-for-sale marketable investment securities and federal funds sold. The fair value of the available-for-sale investment portfolio was $187.5 million at September 30, 2018. We pledge portions of our investment securities portfolio to secure public fund deposits, derivative positions and Federal Home Loan Bank (“FHLB”) advances. At September 30, 2018, total investment securities pledged for these purposes comprised 78% of the estimated fair value of the entire investment portfolio, leaving $42.6 million of unpledged securities.

We have a large base of non-maturity customer deposits, defined as demand, savings, and money market deposit accounts. At September 30, 2018, such deposits totaled $924.0 million and represented 82% of our total deposits.

38

Other sources of funds available to meet daily needs include FHLB advances. As a member of the FHLB of Cincinnati, the Company has access to credit products offered by the FHLB. The Company views these borrowings as a low cost alternative to other time deposits. At September 30, 2018, available credit from the FHLB totaled $59.4 million. Additionally, we had available federal funds purchased lines with correspondent banks totaling $110.0 million at September 30, 2018.

The principal source of cash for CapStar Financial Holdings, Inc. (the “Parent Company”) is dividends paid to it as the sole shareholder of the Bank. At September 30, 2018, the Bank was able to pay up to $23.5 million in dividends to the Parent Company without regulatory approval subject to the ongoing capital requirements of the Bank.

Accordingly, management believes that our funding sources are at sufficient levels to satisfy our short-term and long-term liquidity needs.

(d) Capital Resources

At September 30, 2018, shareholders’ equity totaled $157.5 million, an increase of $10.6 million since December 31, 2017. Accordingly, as of September 30, 2018, the Company and the Bank were well-capitalized under the regulatory framework for prompt corrective action.  See the Consolidated Statement of Changes in Shareholders’ Equity and Note 10 of the consolidated financial statements for further detail of the changes in equity since the end of 2017.

Off-Balance Sheet Arrangements

In the normal course of business, we enter into various transactions that, in accordance with GAAP, are not included in our consolidated balance sheet.  We enter into these transactions to meet the financing needs of our clients. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in our consolidated balance sheets. Most of these commitments mature within two years and are expected to expire without being drawn upon.  Standby letters of credit are included in the determination of the amount of risk-based capital that the Company and the Bank are required to hold.

We enter into contractual loan commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of our commitments to extend credit are contingent upon clients maintaining specific credit standards until the time of loan funding.

Standby letters of credit are written conditional commitments issued by us to guarantee the performance of a client to a third party. In the event that the client does not perform in accordance with the terms of the agreement with the third party, we would be required to fund the commitment.  The maximum potential amount of future payments we could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, we would be entitled to seek recovery from the client.  Our policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

We minimize our exposure to loss under loan commitments and standby letters of credit by subjecting them to the same credit approval and monitoring procedures as we do for on-balance sheet instruments.  We assess the credit risk associated with certain commitments to extend credit and establish a liability for probable credit losses.  The effect on our revenue, expenses, cash flows and liquidity of the unused portions of these commitments cannot be reasonably predicted because there is no guarantee that the lines of credit will be used.

Our off-balance sheet arrangements are summarized in Note 7 of the consolidated financial statements.

(e) Non-GAAP Financial Measures

This Report includes the following financial measures that have been prepared other than in accordance with generally accepted accounting principles in the United States (“non-GAAP financial measures”): tangible common equity, tangible common equity to total tangible assets and tangible common equity per share. The Company believes that these non-GAAP financial measures (i) provide useful information to management and investors that is supplementary to its financial condition, results of operations and cash flows computed in accordance with GAAP, (ii) enable a more complete understanding of factors and trends affecting the Company’s business, and (iii) allow investors to evaluate the Company’s performance in a manner similar to management, the financial services industry, bank stock analysts and bank regulators; however, the Company acknowledges that its non-GAAP financial measures have a number of limitations.  As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other companies use.

The following table presents a reconciliation of tangible common equity, tangible common equity to total tangible assets and tangible common equity per share to the most directly comparable GAAP financial measures.

(f) Recently Issued Accounting Pronouncements

ASU 2014-09, Revenue from Contracts with Customers

In May 2014, the FASB issued guidance to change the recognition of revenue from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance was effective for the Company for reporting periods beginning after December 15, 2017 and had no significant impact on financial reporting.

The Company's revenue is comprised of net interest income and noninterest income. The scope of the guidance explicitly excludes net interest income as well as many other revenues for financial assets and liabilities including loans, leases, securities, and derivatives.  Accordingly, the majority of the Company’s revenues were not affected. The Company has performed an assessment of revenue contracts related to revenue streams that are within the scope of the standard. The accounting policies have not changed since the principles of revenue recognition from the ASU are consistent with existing guidance and current practices applied by our businesses. We have not identified material changes to the timing or amount of revenue recognition nor have we identified a significant need for material changes to disclosures.

ASU 2016-02, Leases

In February 2016, the FASB amended the Leases topic of the Accounting Standards Codification to revise certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.

We expect to adopt the guidance using the modified retrospective method and practical expedients for transition. The practical expedients allow us to largely account for our existing leases consistent with current guidance except for the incremental balance sheet recognition for lessees. We have started an initial evaluation of our leasing contracts and activities. We have also started developing our methodology to estimate the right-of use assets and lease liabilities, which will be based on the present value of lease payments (the December 31, 2017 future minimum lease payments were $14.6 million). We do not expect a material change to the timing of expense recognition, but we are early in the implementation process and will continue to evaluate the impact. We are evaluating our existing disclosures and may need to provide additional information as a result of adoption of the ASU.

ASU 2016-13, Financial Instruments – Credit Losses

In September 2016, the FASB issued guidance to change the accounting for credit losses and modify the impairment model for certain debt securities. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. Early adoption is permitted for all organizations for periods beginning after December 15, 2018.

The Company will apply the amendments to the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. While early adoption is permitted beginning in first quarter 2019, we do not expect to elect that option. We are evaluating the impact of the ASU on our consolidated financial statements. In addition to our allowance for loan losses, we will also record an allowance for credit losses on debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio's composition and credit quality at the adoption date as well as economic conditions and forecasts at that time.

ASU 2017-04, Simplifying the Test of Goodwill Impairment

In January 2017, the FASB amended the Goodwill and Other Topic of the Accounting Standards Codification to simplify the accounting for goodwill impairment for public business entities and other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. The amendment removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill.  The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2019.

ASU 2017-09, Scope of Modification Accounting

In May 2017, the FASB amended the requirements in the Compensation—Stock Compensation Topic of the Accounting Standards Codification related to changes to the terms or conditions of a share-based payment award. The amendments provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The amendments were effective for the Company for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The Company adopted the amendments during the period ended March 31, 2018. These amendments did not have a material effect on the Company’s financial statements.

41

ASU 2017-12, Derivatives and Hedging:  Targeted Improvements to Accounting for Hedging Activities

In August 2017, the FASB amended the requirements of the Derivatives and Hedging Topic of the Accounting Standards Codification to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company adopted this standard December 1, 2017.  There was no material effect on the financial statements.

ASU 2018-02, Income Statement: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income

In February 2018, the FASB Issued (2018-02), Income Statement (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows Companies to reclassify the stranded effects in other comprehensive income to retained earnings as a result of the change in the tax rates under the Tax Reform Act. During the period ended December 31, 2017, the Company opted to early adopt this pronouncement by retrospective application to each period in which the effect of the change in the tax rate under the Tax Reform Act is recognized. The Company made an election to reclassify income tax effects of the Tax Reform Act, amounting to approximately $259,000, from accumulated other comprehensive income to retained earnings. The impact of the reclassification from other comprehensive income to retained earnings was included in the Statement of Changes in Shareholders’ Equity for the year ended December 31, 2017.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.

(g) Impact of Inflation

The consolidated financial statements and related consolidated financial data presented herein have been prepared in accordance with U.S. GAAP and practices within the banking industry which require the measurement of financial position and operating results in terms of historical dollars without considering the changes in the relative purchasing power of money over time due to inflation. Unlike most industrial companies, virtually all the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution's performance than the effects of general levels of inflation.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Information required by this item is included in Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Interest Rate Simulation Sensitivity Analysis.”

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company, with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report.  Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Report, the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed in the Company’s filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and to ensure that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting that occurred during the period covered by this Report that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

General

From time to time, the Company is party to legal actions that are routine and incidental to its business.  Given the nature, scope and complexity of the extensive legal and regulatory landscape applicable to the Company’s business, including laws and regulations governing consumer protection, fair lending, fair labor, privacy, information security and anti-money laundering and anti-terrorism laws, the Company, like all banking organizations, is subject to heightened legal and regulatory compliance and litigation risk.  However, based upon available information and in consultation with legal counsel, management does not expect the ultimate disposition of any or a combination of these actions to have a material adverse effect on the Company’s assets, business, cash flow, condition (financial or otherwise), liquidity, prospects and\or results of operations.

Litigation Against Gaylon M. Lawrence & The Lawrence Group

On October 31, 2017, CapStar filed a complaint, captioned CapStar Financial Holdings, Inc. v. Gaylon M. Lawrence & The Lawrence Group, Case No. 3:17-cv-01421, in the U.S. District Court for the Middle District of Tennessee, in connection with Mr. Lawrence and The Lawrence Group's acquisition of CapStar stock. The complaint alleges that defendants violated Section 13(d) of the Securities Exchange Act of 1934 (the "Exchange Act") by filing materially false and misleading Schedules 13D regarding defendants' acquisition of a minority stake (1,156,675 shares) of CapStar stock. It also alleged that defendants violated the Change in Bank Control Act, 12 U.S.C. § 1817(j) (the "CBCA"), by attempting to acquire control of CapStar without first receiving approval from the Federal Reserve, and also that defendants violated Tennessee Code Section 45-2-107 by controlling banks without having registered as a bank holding company. 

By order dated December 18, 2017, the court granted CapStar's motion for expedited discovery, which is presently underway. Defendants have filed a motion to dismiss the action as well as a separate motion to stay.  The motion to stay was denied by the court on May 21, 2018.  On September 24, 2018, the court denied in part and granted in part defendants' motion to dismiss, permitting CapStar's claims that defendants violated Tennessee Code Section 45-2-107 under Section 13(d) of the Exchange Act to proceed.

Mr. Lawrence has also filed an Interagency Notice of Change in Control pursuant to the CBCA with the Federal Reserve on October 30, 2017, seeking permission to acquire up to 15% of the outstanding voting shares of CapStar's common stock. At the Federal Reserve's direction, on March 13, 2018, Mr. Lawrence requested that the Federal Reserve suspend processing of this notice.On November 6, 2018, the Federal Reserve notified the Company that it has determined not to disapprove the notice, subject to compliance by Mr. Lawrence and his affiliates with extensive representations and commitments set forth in correspondence between Mr. Lawrence and the Federal Reserve.

All of the shares were sold pursuant to our Registration Statement on Form S-1, as amended (File No. 333-213367), which was declared effective by the SEC on September 21, 2016. The offering did not terminate until all of the shares offered were sold.  The Company made no payments to its directors, officers or persons owning ten percent or more of its common stock or to their associates, or to its affiliates in connection with the issuance and sale of the common stock.  Keefe, Bruyette & Woods, Inc. and Sandler O’Neill & Partners, L.P. acted as lead book-running managers for the IPO. Our common stock is currently trading on the Nasdaq Global Select Market under the symbol “CSTR.”

There has been no material change in the planned use of proceeds from our IPO as described in our prospectus filed with the SEC on September 23, 2016 pursuant to Rule 424(b)(4) under the Securities Act.   Pending application of the IPO proceeds, we have investedthe net proceeds in short-term investments.

Summary of Significant Accounting Policies

NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements as of and for the period ended September 30, 2018 include CapStar Financial Holdings, Inc. and its wholly owned subsidiary, CapStar Bank (the “Bank”, together referred to as the “Company”). Significant intercompany transactions and accounts are eliminated in consolidation.

The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods presented have been included.  These unaudited consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and related notes appearing in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, determination of impairment of intangible assets, including goodwill, the valuation of our investment portfolio, deferred tax assets and estimated liabilities.  There have been no significant changes to the Company’s critical accounting policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Subsequent Events

Accounting Standards Codification (“ASC”) 855, Subsequent Events, establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued. The Company evaluated all events or transactions that occurred after September 30, 2018 through the date of the issued financial statements.

Security fair values are established by an independent pricing service as of the dates indicated. The difference between amortized cost and fair value reflects current interest rates and represents the potential gain (loss) had the portfolio been liquidated on those dates. Security gains (losses) are realized only in the event of dispositions prior to maturity or other-than-temporary impairment. Securities with unrealized losses as of September 30, 2018 and December 31, 2017, and the length of time they were in continuous loss positions as of such dates are as follows (dollars in thousands):

As noted in the table above, as of September 30, 2018, the Company had unrealized losses of $7.1 million in its investment securities portfolio. The unrealized losses associated with these investment securities are driven by changes in interest rates and are recorded as a component of equity. These investment securities will continue to be monitored as a part of our ongoing impairment analysis. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments. If a shortfall in future cash flows is identified, a credit loss will be deemed to have occurred and will be recognized as a charge to earnings and a new cost basis for the security will be established.

Because the Company currently does not intend to sell any investment securities that have an unrealized loss at September 30, 2018, and it is not more-likely-than-not that we will be required to sell these investment securities before recovery of their amortized cost bases, which may be at maturity, we do not consider these securities to be other-than-temporarily impaired at September 30, 2018.

Securities with a market value of $148.7 million at September 30, 2018 were pledged to collateralize public deposits, derivative positions and Federal Home Loan Bank advances.

Results from sales of debt and equity securities were as follows (dollars in thousands):

	Nine Months Ended			Nine Months Ended

The amortized cost and fair value of securities at September 30, 2018, by contractual maturity, are shown below (dollars in thousands). Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

NOTE 3 – LOANS AND ALLOWANCE FOR LOAN LOSSES

A summary of the loan portfolio as of September 30, 2018 and December 31, 2017 follows (dollars in thousands):

Allowance for loan losses		(15,218	)		(13,721	)
Total loans, net	$	1,058,652		$	933,816

The adequacy of the allowance for loan losses (ALL) is assessed at the end of each quarter. The ALL includes a specific component related to loans that are individually evaluated for impairment and a general component related to loans that are segregated into homogenous pools and collectively evaluated for impairment.  The ALL factors applied to these pools are an estimate of probable incurred losses based on management’s evaluation of historical net losses from loans with similar characteristics, which are adjusted by management to reflect current events, trends, and conditions. The adjustments include consideration of the following:  changes in lending policies and procedures, economic conditions, nature and volume of the portfolio, experience of lending management, volume and severity of past due loans, quality of the loan review system, value of underlying collateral for collateral dependent loans, concentrations, and other external factors.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes all commercial loans, and consumer relationships with an outstanding balance greater than $500,000, individually and assigns each loan a risk rating. This analysis is performed on a continual basis by the relationship managers and credit department personnel. On at least an annual basis an independent party performs a formal credit risk review of a sample of the loan portfolio. Among other things, this review assesses the appropriateness of the loan’s risk rating. The Company uses the following definitions for risk ratings:

Special Mention – A special mention asset possesses deficiencies or potential weaknesses deserving of management’s attention. If uncorrected, such weaknesses or deficiencies may expose the Company to an increased risk of loss in the future.

Substandard – A substandard asset is inadequately protected by the current sound net 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 Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.

Doubtful – A doubtful asset has all weaknesses inherent in one classified substandard, with the added characteristic that weaknesses make collection or liquidation in full, on the basis of existing facts, conditions, and values, highly questionable and improbable. The probability of loss is extremely high, but certain important and reasonable specific pending factors which may work to the advantage and strengthening of the asset exist, therefore, its classification as an estimated loss is deferred until a more exact status may be determined. Pending factors include proposed merger, acquisition or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans.

Loans not falling into the criteria above are considered to be pass-rated loans. The Company utilizes six loan grades within the pass risk rating.

The following tables present the loan balances by category as well as risk rating (dollars in thousands):

As of September 30, 2018 and December 31, 2017, all loans classified as nonperforming were deemed to be impaired.

As of both September 30, 2018 and December 31, 2017, the Company had a recorded investment in TDR of $1.1 million. The Company had no specific allowance for those loans at September 30, 2018 or December 31, 2017 and there were no commitments to lend additional amounts.  Loans accounted for as TDR include modifications from original terms such as those due to bankruptcy proceedings, certain modifications of amortization periods or extended suspension of principal payments due to customer financial difficulties.  In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification.  This evaluation is performed under the Bank’s loan policy.  Loans accounted for as TDR are individually evaluated for impairment.

There were no TDR identified during the three or nine months ended September 30, 2018 or 2017.  There were no TDR for which there was a payment default within twelve months following the modification during the three or nine months ended September 30, 2018 or 2017.

A loan is considered to be in payment default once it is 30 days contractually past due under the modified terms.

Income Taxes

NOTE 6 – INCOME TAXES

The Company’s effective tax rate for the three and nine months ended September 30, 2018 was 13.2% and 14.1% compared to 25.5% and 9.1% for the three and nine months ended September 30, 2017.  In March 2016, the FASB issued guidance to simplify several aspects of the accounting for share-based payment award transactions, including income tax consequences. In addition to other changes, the guidance changes the accounting for excess tax benefits and tax deficiencies from generally being recognized in additional paid-in capital to recognition as income tax expense or benefit in the period they occur. The Company adopted the new guidance in the first quarter of 2017. As a result, the Company’s income tax expense was reduced by $422,000 and $1,062,000 for the three and nine months ended September 30, 2018, respectively, and by $144,000 and $310,000 for the three and nine months ended September 30, 2017, respectively.

On December 22, 2017, Public Law 115-97, informally referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”) was enacted into law. The Tax Reform Act provides for significant changes to the U.S. tax code that impact businesses. Effective January 1, 2018, the Tax Reform Act reduced the U.S. federal tax rate for corporations from 35% to 21% for U.S. taxable income.

The effective tax rate compared favorably to the statutory federal rate of 21% and Tennessee excise tax rate of 6.5% primarily due to investments in qualified municipal securities, company owned life insurance, state tax credits, net of the effect of certain non-deductible expenses and the recognition of excess tax benefits related to stock compensation.

The notional amount of the interest rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.

Interest Rate Swaps Designated as Cash Flow Hedges

Forward starting interest rate swaps with notional amounts totaling $20 million as of September 30, 2018 and December 31, 2017 were designated as cash flow hedges of certain liabilities and were determined to be fully effective during all periods presented. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the swaps is recorded in other assets (liabilities) with changes in fair value recorded in other comprehensive income (loss). The amount included in accumulated other comprehensive income (loss) would be reclassified to current earnings should the hedges no longer be considered effective. The Company expects the hedges to remain fully effective during the remaining terms of the swaps.

Summary information about the interest-rate swaps designated as cash flow hedges was as follows (dollars in thousands):

	September 30, 2018			December 31, 2017
Notional amounts	$	20,000		$	20,000

Fair value	$	(462	)	$	(1,375	)
Amount of unrealized loss recognized in accumulated    other comprehensive income, net of tax	$	(341	)	$	(1,016	)

Pursuant to its interest rate swap agreements, the Company pledged collateral to the counterparties in the form of investment securities with a market value of $2.1 million at September 30, 2018. There was no collateral posted from the counterparties to the Company as of September 30, 2018. It is possible that the Company may need to post additional collateral in the future or that the counterparties may be required to post collateral to the Company in the future.

Other Interest Rate Swaps

The Company also enters into swaps to facilitate customer transactions and meet their financing needs.  Upon entering into these transactions the Company enters into offsetting positions with large U.S. financial institutions in order to minimize risk to the Company.

Stock Options and Restricted Shares

NOTE 9 - STOCK OPTIONS AND RESTRICTED SHARES

During 2008, the board of directors of the Bank approved the CapStar Bank 2008 Stock Incentive Plan. Following the formation of CapStar Financial Holdings, Inc. in 2016, and in connection with the Share Exchange, the outstanding awards of restricted stock and stock options under the CapStar Bank 2008 Stock Incentive Plan were exchanged for similar awards of restricted stock and stock options issued by CapStar Financial Holdings, Inc. under the CapStar Financial Holdings, Inc. Stock Incentive Plan (the “Plan”), which the board of directors adopted in 2016. The Stock Incentive Plan provides for the grant of stock-based incentives, including stock options, restricted stock units, performance awards and restricted stock, to employees, directors and service providers that are subject to forfeiture until vesting conditions have been satisfied by the award recipient under the terms of the award.  The Plan is intended to help align the interests of employees and our shareholders and reward our employees for improved Company performance.  The Plan reserved 1,569,475 shares of stock for issuance of stock incentives. In April 2018 the board of directors reserved an additional 400,000 shares of stock for issuance of stock incentives.  Stock incentives include both restricted share and stock option grants.  Total shares issuable under the plan were 506,435 at September 30, 2018.

The Company has recognized stock-based compensation expense, within salaries and employee benefits for employees, and within other non-interest expense for directors, in the consolidated statements of income as follows (dollars in thousands):

	Three Months Ended						Nine Months Ended
	September 30,						September 30,
	2018			2017			2018			2017
Stock-based compensation expense before income taxes	$	310		$	288		$	940		$	771
Less: deferred tax benefit		(81	)		(110	)		(246	)		(295	)
Reduction of net income	$	229		$	178		$	694		$	476

Restricted Shares

Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at the issue date. The fair value of each restricted stock grant is based on valuations performed by independent consultants. The recipients have the right to vote and receive dividends but cannot sell, transfer, assign, pledge, hypothecate, or otherwise encumber the restricted stock until the shares have vested. Restricted shares fully vest on the third anniversary of the grant date.  A summary of the changes in the Company’s nonvested restricted shares for the nine months ended September 30, 2018 follows:

				Weighted
				Average
	Restricted			Grant Date
Nonvested Shares	Shares			Fair Value
Nonvested at beginning of period		187,253		$	14.21

Forfeited		(8,065	)		15.95
Nonvested at end of period		133,454		$	17.28

As of September 30, 2018, there was $1.6 million of unrecognized compensation cost related to nonvested shares granted under the Plan.  The cost is expected to be recognized over a weighted-average period of 2.0 years.  The total fair value of shares vested during the nine months ended September 30, 2018 and 2017 was $1.9 million and $1.1 million.

Stock Options

Option awards are generally granted with an exercise price equal to the fair value of the Company’s common stock at the date of grant.  Option awards generally have a four year vesting period and a ten year contractual term.

The fair value of each option grant is estimated on the date of grant using the Black Scholes option pricing model. There were no options granted in 2018 or 2017.

A summary of the activity in stock options for the nine months ended September 30, 2018 follows:

Banking And Thrift [Abstract]

Regulatory Capital Requirements

NOTE 10 – REGULATORY CAPITAL REQUIREMENTS

The Company and the Bank are subject to regulatory capital requirements administered by the Federal Reserve and the Bank is also subject to the regulatory capital requirements of the Tennessee Department of Financial Institutions. Failure to meet capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that could, in that event, have a material adverse effect on the institutions’ financial statements. The relevant regulations require the Company and the Bank to meet specific capital adequacy guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting principles. The capital classifications of the Company and the Bank are also subject to qualitative judgments by their regulators about components, risk weightings, and other factors. Those qualitative judgments could also affect the capital status of the Company and the Bank and the amount of dividends the Company and the Bank may distribute. The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Bank on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of September 30, 2018, the Company and the Bank met all regulatory capital adequacy requirements to which they are subject.

The Company’s and the Bank’s capital amounts and ratios as of September 30, 2018 and December 31, 2017 are presented in the following table (dollars in thousands).

Fair Value Disclosures [Abstract]

Fair Value

NOTE 12 – FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2: Significant observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Bank used the following methods and significant assumptions to estimate fair value:

Investment Securities: The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded and, values debt securities by relying on quoted prices for the specific securities and the securities’ relationship to other benchmark quoted securities (Level 2 inputs). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). See below for additional discussion of Level 3 valuation methodologies and significant inputs. The fair values of all securities are determined from third party pricing services without adjustment.

Derivatives-Interest Rate Swaps: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2). The Bank’s derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, the fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.  The fair values of all interest rate swaps are determined from third party pricing services without adjustment.

Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on at least a quarterly basis for additional impairment and adjusted in accordance with the loan policy.

Other Real Estate Owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Appraisals may be adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and/or management’s expertise and knowledge of the collateral. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly.  The Company had no other real estate owned at September 30, 2018 or December 31, 2017.

Loans Held For Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2).  There were no loans held for sale carried at fair value at September 30, 2018 or December 31, 2017.

The methods and assumptions, not previously presented, used to estimate fair values are described as follows:

(a) Cash and Due from Banks, Interest-Bearing Deposits in Financial Institutions

For these short‑term instruments, the carrying amount is a reasonable estimate of fair value.

(b) Federal Funds Sold

Federal funds sold clear on a daily basis. For this reason, the carrying amount is a reasonable estimate of fair value.

(c) Restricted Equity Securities

It is not practical to determine the fair value of restricted securities due to restrictions placed on their transferability.

(d) Loans, net

During the first quarter of 2018, the Company adopted ASU 2016-01, “Recognition and Measurement of Financial Assets and Liabilities.”  The amendments included within this standard, which are applied prospectively, require the Company to disclose fair value of financial instruments measured at amortized cost on the balance sheet to measure that fair value using an exit price notion.  Prior to adopting the amendments included in the standard, the Company was allowed to measure fair value under an entry price notion.  The entry price notion previously applied by the Company used a discounted cash flows technique to calculate the present value of expected future cash flows for a financial instrument.  The exit price notion uses the same approach, but also incorporates other factors, such as enhanced credit risk, illiquidity risk and market factors that sometimes exist in exit prices in dislocated markets.  

As of September 30, 2018, the technique used by the Company to estimate the exit price of the loan portfolio consists of similar procedures to those used as of December 31, 2017, but with added emphasis on both illiquidity risk and credit risk not captured by the previously applied entry price notion. The fair value of the Company’s loan portfolio has always included a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk as described above.  However, under the new guidance, the Company believes a further credit risk discount must be applied through the use of a discounted cash flow model to compensate for illiquidity risk, based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of enhanced credit risk provides an estimated exit price for the Company’s loan portfolio.

For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral.

As of December 31, 2017, the fair value of the Company’s loan portfolio includes a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk. For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral. For other loans, fair values are estimated using discounted cash flow models, using current market interest rates offered for loans with similar terms to borrowers of similar credit quality. The values derived from the discounted cash flow approach for each of the above portfolios are then further discounted to incorporate credit risk. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price as of December 31, 2017.

(e) Accrued Interest Receivable

The carrying amounts of accrued interest approximate fair value.

(f) Other Assets

Included in other assets are bank owned life insurance, certain interest rate swap agreements and the cash flow hedge relationships. The fair values of interest rate swap agreements and the cash flow hedge relationships are based on independent pricing services that utilize pricing models with observable market inputs. For bank owned life insurance, the carrying amount is based on the cash surrender value and is a reasonable estimate of fair value.

(g) Deposits

The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of certificates of deposit is estimated by discounted cash flow models, using current market interest rates offered on certificates with similar remaining maturities.

(h) Federal Home Loan Bank Advances

The fair value of fixed rate Federal Home Loan Bank Advances is estimated using discounted cash flow models, using current market interest rates offered on certificates, advances and other borrowings with similar remaining maturities.

(i) Other Liabilities

Included in other liabilities are accrued interest payable, certain interest rate swap agreements, the cash flow hedge relationships and contingent consideration. The fair values of interest rate swap agreements and the cash flow hedge relationships are based on independent pricing services that utilize pricing models with observable market inputs.  The fair value of contingent consideration is estimated by a discounted cash flow model that utilizes various unobservable inputs.  The carrying amounts of accrued interest approximate fair value.

(j) Off-Balance Sheet Instruments

Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing.  The fair value of commitments is not material.

(k) Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on estimating on and off‑balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, fixed assets are not considered financial instruments and their value has not been incorporated into the fair value estimates. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

NOTE 13 – SUBSEQUENT EVENT

On October 1, 2018, pursuant to the Agreement and Plan of Merger, dated as of June 11, 2018 (the “Merger Agreement”), by and between CapStar Financial Holdings, Inc., a Tennessee corporation (“CapStar”), and Athens Bancshares Corporation, a Tennessee corporation (“Athens”), Athens was merged with and into CapStar, with CapStar continuing as the surviving entity (the “Merger”). Immediately following the Merger, Athens Federal Community Bank, National Association, a wholly owned subsidiary of Athens, merged with and into CapStar Bank, a wholly owned subsidiary of CapStar (the “Bank Merger”), with CapStar Bank continuing as the surviving entity in the Bank Merger.

On the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01, of Athens (“Athens Common Stock”) issued and outstanding immediately prior to the completion of the merger (other than dissenting shares and shares of Athens common stock owned directly or indirectly by Athens, CapStar and their wholly owned subsidiaries (in each case, other than shares of Athens common stock held in a fiduciary capacity or in connection with debts previously contracted) was converted into the right to receive 2.864 shares (the “Exchange Ratio”) of voting common stock, par value $1.00 per share, of CapStar (“CapStar Common Stock”), with cash paid in lieu of fractional shares. This resulted in the issuance of 5,181,916 shares of CapStar common stock on October 1, 2018.

At the Effective Time, each outstanding and unexercised Athens stock option granted under the Athens Bancshares Corporation 2010 Equity Incentive Plan (the “Athens Equity Plan”) that was held by an employee or service provider of Athens who had terminated service prior to the Effective Time was cancelled and converted into the right to receive the cash value of the merger consideration (determined in accordance with the terms of the Merger Agreement), less the applicable option exercise price and less applicable withholding taxes. Except as described in the prior sentence, each outstanding and unexercised Athens stock option granted under the Athens Equity Plan was converted into an option to purchase shares of CapStar Common Stock, with the number of shares and exercise price adjusted to reflect the Exchange Ratio in accordance with the terms of the Merger Agreement. The converted options resulted in the right to purchase 548,051 shares of CapStar Common Stock at a weighted average exercise price of $5.06.

Total acquisition consideration resulting from the Merger amounted to approximately $92.9 million.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which was attached as Exhibit 2.1 to CapStar’s Form 8-K filed with the U.S. Securities and Exchange Commission on June 14, 2018 and the terms of which are incorporated herein by reference.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, determination of impairment of intangible assets, including goodwill, the valuation of our investment portfolio, deferred tax assets and estimated liabilities.  There have been no significant changes to the Company’s critical accounting policies as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.
