NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission and follow general practices within the banking industry. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of Management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three months ended March 31, 2016 are not necessarily indicative of the results expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015.

Note 2: Accounting Policies

The most significant accounting policies followed by the Company are presented in Note 1 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts to the methods, assumptions, and estimates underlying those amounts, Management has identified the allowance for loan losses accounting to be the accounting area requiring the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available. A discussion of the factors affecting accounting for the allowance for loan losses and purchased loans is included in the “Loan Portfolio Credit Risk” discussion below. Certain amounts in prior periods have been reclassified to conform to the current presentation.

Application of these principles requires the Company to make certain estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment writedown or valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by other third-party sources, when available.

Recently Issued Accounting Standards

FASB Accounting Standards Update (ASU) 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, was issued January 2016. The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most notably, the ASU changes the income statement impact of equity investments held by the Company and the requirement for the Company to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.

The Company will be required to adopt the ASU provisions on January 1, 2018. Management is evaluating the impact that the ASU will have on the Company’s financial statements.

FASB Accounting Standards Update (ASU) 2016-02, Leases (Topic 842), was issued February 25, 2016. The provisions of the new standard require lessees to recognize most leases on-balance sheet, increasing reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP.

The Company will be required to adopt the ASU provisions January 1, 2019, utilizing the modified retrospective transition approach. Management is evaluating the impact that the ASU will have on the Company’s financial statements.

- 9 -

FASB ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, was issued March 30, 2016. The provisions of the new standard changes several aspects of the accounting for share-based payment award transactions, including: (1) Accounting and Cash Flow Classification for Excess Tax Benefits, (2) Forfeitures, and (3) Tax Withholding Requirements and Cash Flow Classification.

The Company will be required to adopt the ASU provisions January 1, 2017. Management is evaluating the impact that the ASU will have on the Company’s financial statements.

Expected maturities of mortgage-related securities can differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may affect the yield on the carrying value of mortgage-related securities. At March 31, 2016 and December 31, 2015, the Company had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

The unrealized losses on the Company’s investment securities were caused by market conditions for these types of investments, particularly changes in risk-free interest rates. The Company evaluates securities on a quarterly basis including changes in security ratings issued by ratings agencies, changes in the financial condition of the issuer, and, for mortgage-backed and asset-backed securities, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a major rating agency. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities.

The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2016.

The fair values of the investment securities could decline in the future if the general economy deteriorates, inflation increases, credit ratings decline, the issuer’s financial condition deteriorates, or the liquidity for securities declines. As a result, other than temporary impairments may occur in the future.

As of March 31, 2016, $712,412 thousand of investment securities were pledged to secure public deposits and short-term borrowed funds. As of December 31, 2015, $738,865 thousand of investment securities were pledged to secure public deposits and short-term borrowed funds.

The Bank’s customers are small businesses, professionals and consumers. Given the scale of these borrowers, corporate credit rating agencies do not evaluate the borrowers’ financial condition. The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for loss recognition, as “substandard,” “doubtful,” and “loss.” Loan Review Department evaluations occur every calendar quarter. If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review Department examinations, assigned risk grades are re-evaluated promptly. Credit risk grades assigned by the Loan Review Department are subject to review by the Bank’s regulatory authorities during regulatory examinations.

Note 9: Fair Value Measurements

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale investment securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, impaired loans, certain loans held for investment, investment securities held to maturity, and other assets. These nonrecurring fair value adjustments typically involve the lower-of-cost-or-fair value accounting of individual assets.

In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for an asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance.

The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. When the valuation assumptions used to measure the fair value of the asset or liability are categorized within different levels of the fair value hierarchy, the asset or liability is categorized in its entirety within the lowest level of the hierarchy. These levels are:

- 23 -

Level 1 – Valuation is based upon quoted prices for identical instruments traded in active exchange markets, such as the New York Stock Exchange. Level 1 includes U.S. Treasury and equity securities, which are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 includes federal agency securities, mortgage-backed securities, corporate securities, asset-backed securities, and municipal bonds.

Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

The Company relies on independent vendor pricing services to measure fair value for investment securities available for sale and investment securities held to maturity. The Company employs three pricing services. To validate the pricing of these vendors, the Company compares vendors’ pricing for each of the securities for consistency; significant pricing differences, if any, are evaluated using all available independent quotes with the quote closely affecting the market generally used as the fair value estimate. In addition, the Company conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; securities selected for OTTI analysis include all securities at a market price below 95 percent of par value or with a market to book ratio below 95:100. As with any valuation technique used to estimate fair value, changes in underlying assumptions used could significantly affect the results of current and future values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities.

The Company regularly reviews the valuation techniques and assumptions used by its vendors and determines which valuation techniques are utilized based on observable market inputs for the type of securities being measured. The Company uses the information to determine the placement in the fair value hierarchy as level 1, 2 or 3. When the Company changes its valuation assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, or reevaluates the valuation techniques and assumptions used by its vendors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new information. The Company recognizes these transfers at the end of the reporting period that the transfers occur. For the three months ended March 31, 2016 and 2015, there were no transfers in or out of levels 1, 2 or 3. During the quarter ended June 30, 2015, the Company reevaluated the valuation techniques and assumptions used by its vendors in valuing the Company’s available for sale securities, and based on the evaluation, transferred $437,715 thousand out of level 1 and transferred $437,715 thousand into level 2. There were no transfers into level 1 or into or out of level 3. Subsequent to June 30, 2015 and through the year ended December 31, 2015, there were no transfers into or out of levels 1, 2 or 3.

Assets Recorded at Fair Value on a Nonrecurring Basis

The Company may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost or fair-value accounting of individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the balance sheet at March 31, 2016 and December 31, 2015, the following table provides the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets at period end.

	At March 31, 2016								For the Three Months Ended March 31, 2016
	Carrying Value		Level 1		Level 2		Level 3		Total Losses

Total assets measured at fair value on a nonrecurring basis	$	24,897	$	-	$	-	$	24,897	$	(769	)

Level 3 – Valuation is based upon independent market prices, estimated liquidation values of loan collateral or appraised value of the collateral as determined by third-party independent appraisers, less 10% for selling costs, generally. Level 3 includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and impaired loans collateralized by real property and other business asset collateral where a specific reserve has been established or a chargeoff has been recorded. Losses on other real estate owned represent losses recognized in earnings during the period subsequent to its initial classification as foreclosed assets. The unobservable inputs and qualitative information about the unobservable inputs are not presented due to the unavailability from third party evaluators.

Disclosures about Fair Value of Financial Instruments

The following section describes the valuation methodologies used by the Company for estimating fair value of financial instruments not recorded at fair value in the balance sheet.

Cash and Due from Banks Cash and due from banks represent U.S. dollar denominated coin and currency, deposits at the Federal Reserve Bank and correspondent banks, and amounts being settled with other banks to complete the processing of customers’ daily transactions. Collectively, the Federal Reserve Bank and financial institutions operate in a market in which cash and due from banks transactions are processed continuously in significant daily volumes honoring the face value of the U.S. dollar.

Investment Securities Held to Maturity The fair values of investment securities were estimated using quoted prices as described above for Level 2 valuation.

Loans Loans were separated into two groups for valuation. Variable rate loans, except for those described below, which reprice frequently with changes in market rates were valued using historical cost. Fixed rate loans and variable rate loans that have reached their minimum contractual interest rates were valued by discounting the future cash flows expected to be received from the loans using current interest rates charged on loans with similar characteristics. Additionally, the allowance for loan losses of $29,487 thousand at March 31, 2016 and $29,771 thousand at December 31, 2015 and the purchased loan discount associated with purchased covered and purchased non-covered loans of $18 thousand and $6,084 thousand, respectively at March 31, 2016 and $152 thousand and $6,432 thousand, respectively at December 31, 2015 were applied against the estimated fair values to recognize estimated future defaults of contractual cash flows. The Company does not consider these values to be a liquidation price for the loans.

- 26 -

Deposit Liabilities Deposits with no stated maturity such as checking accounts, savings accounts and money market accounts can be readily converted to cash or used to settle transactions at face value through the broad financial system operated by the Federal Reserve Bank and financial institutions. The fair value of deposits with no stated maturity is equal to the amount payable on demand. The fair values of time deposits were estimated by discounting estimated future contractual cash flows using current market rates for financial instruments with similar characteristics.

Short-Term Borrowed Funds The carrying amount of securities sold under agreement to repurchase and other short-term borrowed funds approximate fair value due to the relatively short period of time between their origination and their expected realization.

The table below is a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within which the fair value measurements are categorized, excluding financial instruments recorded at fair value on a recurring basis. The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or settled in larger quantities. The carrying amounts in the following table are recorded in the balance sheet under the indicated captions.

The Company has not included assets and liabilities that are not financial instruments, such as goodwill, long-term relationships with deposit, merchant processing and trust customers, other purchased intangibles, premises and equipment, deferred taxes and other assets and liabilities. The total estimated fair values do not represent, and should not be construed to represent, the underlying value of the Company.

The majority of the Company’s standby letters of credit and other commitments to extend credit carry current market interest rates if converted to loans. No premium or discount was ascribed to these commitments because virtually all funding would be at current market rates.

Note 10: Commitments and Contingent Liabilities

Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan commitments were $321,077 thousand and $299,884 thousand at March 31, 2016 and December 31, 2015, respectively. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. Standby letters of credit are primarily issued to support customers’ short-term financing requirements and must meet the Company’s normal credit policies and collateral requirements. Financial and performance standby letters of credit outstanding totaled $23,581 thousand and $26,149 thousand at March 31, 2016 and December 31, 2015, respectively. The Company also had commitments for commercial and similar letters of credit of $-0- thousand at March 31, 2016 and $40 thousand at December 31, 2015. At March 31, 2016 and December 31, 2015, the Company had a reserve for unfunded commitments of $2,593 thousand, included in other liabilities.

Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Based on the advice of legal counsel, the Company does not expect such cases will have a material, adverse effect on its financial position or results of operations. Legal liabilities are accrued when obligations become probable and the amount is reasonably estimable.

Note 11: Earnings Per Common Share

The table below shows earnings per common share and diluted earnings per common share. Basic earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period. Diluted earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period plus the impact of common stock equivalents.

For the three months ended March 31, 2016 and 2015, options to purchase 1,297 thousand and 1,775 thousand shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.

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

Westamerica Bancorporation and subsidiaries’ (the “Company’s”) principal source of revenue is net interest and fee income, which represents interest earned on loans and investment securities (“interest-earning assets”) reduced by interest paid on deposits and other borrowings (“interest-bearing liabilities”). The relatively low level of market interest rates has reduced the spread between interest rates on earning assets and interest bearing liabilities. The Company’s net interest margin and net interest income declined as market interest rates on newly originated loans remain below the yields earned on older-dated loans and on the overall loan portfolio. The Company’s loan portfolio has declined from the first quarter 2015 through the first quarter 2016; Management has been avoiding long-dated, low-yielding loans given historically low interest rates. Management has also maintained, in their opinion, conservative loan underwriting, terms and conditions. During this period, the investment portfolio has grown. The Company has been reducing its exposure to rising interest rates by purchasing shorter-duration investment securities, which have lower yields than longer-duration securities. The changing composition of interest earning assets and low market interest rates has pressured the net interest margin on a fully taxable equivalent (“FTE”) basis. The net interest margin in the first quarter 2016 increased from the fourth quarter 2015 reflecting the Federal Open Market Committee’s (“FOMC”s) 0.25 percent increase in the federal funds rate on December 16, 2015, which increased yields on loans and investment securities with floating rates. In the first quarter 2016 the Company’s average checking and savings deposits were 6 percent higher than in the first quarter 2015. The growth in lower-costing deposit products contributed to lowering the funding cost from 0.06 percent in the first quarter 2015 to 0.05 percent in the first quarter 2016. Management is focused on controlling all noninterest expense levels, particularly due to market interest rate pressure on net interest income.

The Company presents its net interest margin and net interest income on a FTE basis using the current statutory federal tax rate, which is a non-generally accepted accounting principles (GAAP) financial measure. Management believes the FTE basis is valuable to the reader because the Company’s loan and investment securities portfolios contain a relatively large portion of municipal loans and securities that are federally tax exempt. The Company’s tax exempt loans and securities composition may not be similar to that of other banks, therefore in order to reflect the impact of the federally tax exempt loans and securities on the net interest margin and net interest income for comparability with other banks, the Company presents its net interest margin and net interest income on a FTE basis.

The Company’s significant accounting policies (see Note 1 (“Summary Significant Accounting Policies”) to Financial Statements in the Company’s 2015 Form 10-K) are fundamental to understanding the Company’s results of operations and financial condition. There have been no changes to the Company’s significant accounting policies during the first quarter of 2016.

The Company reported first quarter 2016 net income of $14.2 million or $0.56 diluted earnings per common share. These results compare to net income of $14.6 million or $0.57 diluted earnings per common share and $14.6 million or $0.57 diluted earnings per common share for both the first and fourth quarters 2015.

Net Income

Following is a summary of the components of net income for the periods indicated:

	For the Three Months Ended
	March 31,						December 31,
	2016			2015			2015
	(In thousands, except per share data)
Net interest and loan fee income (FTE)	$	36,447		$	36,930		$	36,734
Provision for loan losses		-			-			-
Noninterest income		11,729			12,300			11,305
Noninterest expense		25,858			26,727			25,504
Income before taxes (FTE)		22,318			22,503			22,535
Income tax provision (FTE)		8,092			7,946			7,957
Net income	$	14,226		$	14,557		$	14,578

Average diluted common shares		25,468			25,655			25,555
Diluted earnings per common share	$	0.56		$	0.57		$	0.57

Average total assets	$	5,174,804		$	5,059,537		$	5,168,805
Net income to average total assets (annualized)		1.11	%		1.17	%		1.12	%
Net income to average common shareholders' equity (annualized)		10.85	%		11.44	%		11.01	%

Net income for the first quarter of 2016 was $331 thousand less than the same quarter of 2015, the net result of lower net interest and loan fee income (FTE), lower noninterest income and higher income tax provision (FTE), partially offset by lower noninterest expense. A decrease in net interest and fee income (FTE) was mostly attributed to lower average balances of loans and lower composite yield on investments, partially offset by higher average balances of investments and the effect of one additional accrual day. The provision for loan losses remained zero, reflecting Management's evaluation of losses inherent in the loan portfolio. Noninterest income decreased primarily due to reduced levels of service charges on deposit accounts and lower merchant credit card fees. Noninterest expense decreased mostly due to lower salaries and related benefit expense caused by employee attrition, occupancy cost reductions from branch closures, and lower expense for foreclosed properties. The income tax provision (FTE) was higher in the first quarter 2016 due to reduced levels of federally tax-exempt income on interest-earning assets relative to pre-tax income, and lower tax credits.

Comparing the first quarter of 2016 with the fourth quarter of 2015, net income decreased $352 thousand due to lower net interest and loan fee income (FTE), higher noninterest expense and higher income tax provision (FTE), partially offset by higher noninterest income. The lower net interest and fee income (FTE) was primarily caused by lower average balances of loans and the effect of one less accrual day, partially offset by higher average balances of investments and the effect of the FOMC’s 0.25 percent increase in the federal funds rate on December 16, 2015 on interest-earning assets with floating rates. The provision for loan losses remained zero, reflecting Management's evaluation of losses inherent in the loan portfolio. Noninterest income increased primarily due to higher merchant credit card fees. Noninterest expense increased mostly due to seasonally high payroll taxes, higher expenses for information technology upgrades, partially offset by cost savings from branch closures. Income tax provision (FTE) increased because the fourth quarter 2015 provision (FTE) was higher in the first quarter 2016 due to reduced levels of federally tax-exempt income on interest-earning assets relative to pre-tax income, and lower tax credits.

Net Interest and Loan Fee Income (FTE)

Following is a summary of the components of net interest and loan fee income (FTE) for the periods indicated:

	For the Three Months Ended
	March 31,						December 31,
	2016			2015			2015
	(In thousands)
Interest and loan fee income	$	33,647		$	33,917		$	33,888
Interest expense		552			659			563
FTE adjustment		3,352			3,672			3,409
Net interest and loan fee income (FTE)	$	36,447		$	36,930		$	36,734

Average earning assets	$	4,381,423		$	4,342,031		$	4,411,599
Net interest margin (FTE) (annualized)		3.34	%		3.43	%		3.32	%

Net interest and loan fee income (FTE) decreased during the first quarter 2016 by $483 thousand from the same period in 2015, mainly due to lower average balances of loans (down $183 million) and lower yields on investments (down 1 basis point or “bp”), partially offset by higher average balances of investments (up $223 million), higher yields on loans (up 5 bp) and the effect of one additional accrual day.

Comparing the first quarter of 2016 with the fourth quarter of 2015, net interest and loan fee income (FTE) decreased $287 thousand due to lower average balances of loans (down $43 million) and the effect of one less accrual day, partially offset by higher average balances of investments (up $13 million) and higher yields on interest-earning assets (up 2 bp).

Loan volumes have declined due to problem loan workout activities (such as chargeoffs, collateral repossessions and principal payments), particularly with purchased loans, and reduced volumes of loan originations. In Management’s opinion, current levels of competitive loan pricing do not provide adequate forward earnings potential. As a result, the Company has not currently taken an aggressive posture relative to loan portfolio growth. Management has maintained relatively stable interest-earning asset volumes by increasing investment securities as loan volumes have declined.

Yields on interest-earning assets declined due to relatively low interest rates prevailing in the market. The net interest margin (FTE) was 3.34% in the first quarter 2016, 3.43% in the first quarter 2015 and 3.32% in the fourth quarter 2015. The net interest margin (FTE) was affected by declining market interest rates until the FOMC’s 0.25 percent increase in the federal funds rate on December 16, 2015, which increased yields on loans and investment securities with floating rates. The volume of older-dated higher-yielding loans declined due to principal maturities and paydowns. The Company, in anticipation of rising interest rates, has been purchasing floating rate and shorter-duration investment securities with lower yields than longer-duration securities to increase liquidity. The Company’s high levels of liquidity will provide an opportunity to obtain higher yielding assets assuming market interest rates start rising.

The Company has been replacing higher-cost funding sources with low-cost deposits and interest expense has declined to offset some of the decline in interest income. Average balances of time deposits declined $96 million from the first quarter 2015 to first quarter 2016 while lower-cost checking and savings deposits grew 6% in the same period. Average balances of checking and saving deposits accounted for 93.7% of average total deposits in the first quarter 2016 compared with 91.4% and 93.5% in the first and fourth quarters 2015.

Net Interest Margin (FTE)

The following summarizes the components of the Company's net interest margin for the periods indicated (percentages are annualized.):

	For the Three Months Ended
	March 31,						December 31,
	2016			2015			2015
Yield on earning assets (FTE)		3.39	%		3.49	%		3.37	%
Rate paid on interest-bearing liabilities		0.09	%		0.10	%		0.09	%
Net interest spread (FTE)		3.30	%		3.39	%		3.28	%
Impact of noninterest-bearing funds		0.04	%		0.04	%		0.04	%
Net interest margin (FTE)		3.34	%		3.43	%		3.32	%

During 2015, the net interest margin (FTE) was affected by low market interest rates. The volume of older-dated higher-yielding loans and securities declined due to principal maturities and paydowns. Management has been avoiding long-dated, low-yielding loans given historically low interest rates. Management has also maintained conservative loan underwriting, terms and conditions. During this period, the investment portfolio has grown. The changing composition of interest-earning assets and low market rates has pressured the net interest margin. The increase in the net interest margin from the fourth quarter 2015 to the first quarter 2016 reflects the FOMC’s 0.25% increase in the federal funds rate on December 16, 2015, which increased yields on loans and investment securities which have floating rates. Rates on interest-bearing liabilities were kept low by reducing the volume of higher-cost time deposits.

Summary of Average Balances, Yields/Rates and Interest Differential

The following tables present information regarding the consolidated average assets, liabilities and shareholders’ equity, the amounts of interest income earned from average interest earning assets and the resulting yields, and the amounts of interest expense incurred on average interest-bearing liabilities and the resulting rates. Average loan balances include nonperforming loans. Interest income includes reversal of previously accrued interest on loans placed on non-accrual status during the period and proceeds from loans on nonaccrual status only to the extent cash payments have been received and applied as interest income and accretion of purchased loan discounts. Yields on tax-exempt securities and loans have been adjusted upward to reflect the effect of income exempt from federal income taxation at the current statutory tax rate. Yields, rates and interest margins are annualized.

Provision for Loan Losses

The Company manages credit costs by consistently enforcing, in management’s opinion, conservative underwriting and administration procedures and aggressively pursuing collection efforts with debtors experiencing financial difficulties. The provision for loan losses reflects Management's assessment of credit risk in the loan portfolio during each of the periods presented.

The Company provided no provision for loan losses in the first quarter of 2016 and the first and fourth quarters of 2015. The provision for loan losses is determined based on Management’s evaluation of credit quality for the loan portfolio. The Company recorded purchased County Bank and Sonoma Valley Bank loans at estimated fair value upon the acquisition dates, February 6, 2009 and August 20, 2010, respectively. Such estimated fair values were recognized for individual loans, although small balance homogenous loans were pooled for valuation purposes. The valuation discounts recorded for purchased loans included Management’s assessment of the risk of principal loss under economic and borrower conditions prevailing on the dates of purchase. The purchased County Bank loans secured by single-family residential real estate are “covered” through February 6, 2019 by loss-sharing agreements the Company entered with the FDIC which mitigates losses during the term of the agreements. The FDIC indemnification of purchased County Bank non-single-family residential secured loans expired February 6, 2014. Any deterioration in estimated value related to principal loss subsequent to the acquisition dates requires additional loss recognition through a provision for loan losses. No assurance can be given future provisions for loan losses related to purchased loans will not be necessary. For further information regarding credit risk, the FDIC loss-sharing agreements, net credit losses and the allowance for loan losses, see the “Loan Portfolio Credit Risk” and “Allowance for Loan Losses” sections of this report.

Noninterest Income

The following table summarizes the components of noninterest income for the periods indicated.

	For the Three Months Ended
	March 31,				December 31,
	2016		2015		2015
	(In thousands)

Service charges on deposit accounts	$	5,248	$	5,707	$	5,259
Merchant processing services		1,529		1,703		1,368
Debit card fees		1,516		1,456		1,557
Trust fees		661		706		671
ATM processing fees		658		585		569
Other service fees		629		665		648

Other noninterest income		1,332		1,325		1,065
Total	$	11,729	$	12,300	$	11,305

Noninterest income for the first quarter 2016 declined by $571 thousand or 4.6% from the same period in 2015. Service charges on deposits decreased $459 thousand due to declines in fees charged on overdrawn and insufficient funds accounts (down $232 thousand) and lower fees on analyzed accounts (down $205 thousand). Merchant processing services fees decreased $174 thousand primarily because larger sales relationships with low margins accounted for a significant portion of transaction volumes.

In the first quarter 2016, noninterest income increased $424 thousand or 3.8% compared with the fourth quarter 2015 mostly due to a $161 thousand increase in merchant processing services fees primarily due to the improved margin mix of transaction volumes.

Noninterest Expense

The following table summarizes the components of noninterest expense for the periods indicated.

	For the Three Months Ended
	March 31,				December 31,
	2016		2015		2015
	(In thousands)

Salaries and related benefits	$	13,117	$	13,338	$	12,398

Other noninterest expense		3,707		4,028		3,957
Total	$	25,858	$	26,727	$	25,504

Noninterest expense decreased $869 thousand in the first quarter 2016 compared with the same period in 2015. Salaries and related benefits declined $221 thousand in the first quarter 2016 compared with the same period in 2015 mostly due to employee attrition. Occupancy expense decreased $329 thousand in the first quarter 2016 compared with the same period in 2015 mostly due to branch closures and lease expiration of a non-branch building. Expenses for other real estate owned in the first quarter 2016 included lower net writedowns than in the first quarter 2015. Professional fees increased $184 thousand due to higher legal fees associated with nonperforming assets, partially offset by lower audit fees.

In the first quarter 2016, noninterest expense increased $354 thousand compared with the fourth quarter 2015. Salaries and related benefits increased $719 thousand primarily due to seasonally higher payroll taxes and other employee benefits. Furniture and equipment expense increased $132 thousand mainly due to information technology upgrades. Occupancy expense decreased $363 thousand in the first quarter 2016 compared with the fourth quarter 2015 mostly due to branch closures and lease expiration of a non-branch building.

Provision for Income Tax

During the first quarter 2016, the Company recorded an income tax provision (FTE) of $8.1 million, compared with $7.9 million and $8.0 million for the first and fourth quarters 2015, respectively. The current quarter provision represents an effective tax rate (FTE) of 36.3%, compared with 35.3% for the first and fourth quarters 2015. The higher effective tax rate (FTE) for the first quarter 2016 was attributable to reduced levels of federally tax-exempt income on interest-earning assets relative to pre-tax income, and lower tax credits.

Investment Portfolio

The Company maintains a securities portfolio consisting of securities issued by U.S. Government sponsored entities, agency and non-agency mortgage backed securities, state and political subdivisions, corporations, and asset-backed and other securities. Investment securities are held in safekeeping by an independent custodian.

Management has increased the investment portfolio in response to deposit growth and loan volume declines. The carrying value of the Company’s investment securities portfolio was $2.9 billion as of March 31, 2016, an increase of $58 million compared to December 31, 2015.

Management continually evaluates the Company’s investment securities portfolio in response to established asset/liability management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to which the Company is exposed. These evaluations may cause Management to change the level of funds the Company deploys into investment securities, change the composition of the Company’s investment securities portfolio, and change the proportion of investments allocated into the available for sale and held to maturity investment categories.

The Company’s positioning of the balance sheet for rising interest rates has resulted in the purchase of floating rate corporate bonds, federal agency bonds, mortgage-backed securities, and short-term state and municipal bonds. As of March 31, 2016, substantially all of the Company’s investment securities continue to be investment grade rated by one or more major rating agencies. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset-backed securities.

The Company’s procedures for evaluating investments in securities are in accordance with guidance issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Agencies” (SR 12-15) and other regulatory guidance. Credit ratings are considered in our analysis only as a guide to the historical default rate associated with similarly-rated bonds. There have been no significant differences in our internal analyses compared with the ratings assigned by the third party credit rating agencies.

The following tables summarize the total general obligation and revenue bonds in the Company’s investment securities portfolios as of the dates indicated identifying the state in which the issuing government municipality or agency operates.

At March 31, 2016, the Company’s investment securities portfolios included securities issued by 724 state and local government municipalities and agencies located within 44 states with a fair value of $865.6 million. None of the Company’s investment securities were issued by Puerto Rican government entities. The largest exposure to any one municipality or agency was $10.4 million (fair value) represented by nine general obligation bonds.

Loan Portfolio Credit Risk

The Company extends loans to commercial and consumer customers which expose the Company to the risk borrowers will default, causing loan losses. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans.

The preparation of the financial statements requires Management to estimate the amount of losses inherent in the loan portfolio and establish an allowance for credit losses. The allowance for credit losses is established by assessing a provision for loan losses against the Company’s earnings. In estimating credit losses, Management must exercise judgment in evaluating information deemed relevant, such as financial information regarding individual borrowers, overall credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions and other information. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses.

- 42 -

The Company closely monitors the markets in which it conducts its lending operations and follows a strategy to control exposure to loans with high credit risk. The Bank’s organization structure separates the functions of business development and loan underwriting; Management believes this segregation of duties avoids inherent conflicts of combining business development and loan approval functions. In measuring and managing credit risk, the Company adheres to the following practices.

The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Those loans judged to carry higher risk attributes are referred to as “classified loans.” Classified loans receive elevated management attention to maximize collection.

The Bank maintains two loan administration offices whose sole responsibility is to manage and collect classified loans.

Classified loans with higher levels of credit risk are further designated as “nonaccrual loans.” Management places classified loans on nonaccrual status when full collection of contractual interest and principal payments is in doubt. Uncollected interest previously accrued on loans placed on nonaccrual status is reversed as a charge against interest income. The Company does not accrue interest income on loans following placement on nonaccrual status. Interest payments received on nonaccrual loans are applied to reduce the carrying amount of the loan unless the carrying amount is well secured by loan collateral. “Nonperforming assets” include nonaccrual loans, loans 90 or more days past due and still accruing, and repossessed loan collateral (commonly referred to as “Other Real Estate Owned”).

The former County Bank loans and repossessed loan collateral were purchased from the FDIC with indemnifying loss-sharing agreements. The loss-sharing agreement on single-family residential real estate assets expires February 6, 2019. The loss-sharing agreement on non-single-family residential real estate assets expired February 6, 2014 as to losses and expires February 6, 2017 as to loss recoveries.

Total nonperforming assets	$	26,425	$	22,810	$	24,557

At March 31, 2016, two loans secured by commercial real estate totaling $10,990 thousand were on nonaccrual status. The remaining fourteen nonaccrual loans held at March 31, 2016 had an average carrying value of $481 thousand and the largest carrying value was $1,984 thousand.

Management believes the overall credit quality of the loan portfolio is reasonably stable; however, classified and nonperforming assets could fluctuate from period to period. The performance of any individual loan can be affected by external factors such as the interest rate environment, economic conditions, and collateral values or factors particular to the borrower. No assurance can be given that additional increases in nonaccrual and delinquent loans will not occur in the future.

Allowance for Credit Losses

The Company’s allowance for loan losses represents Management’s estimate of loan losses inherent in the loan portfolio. In evaluating credit risk for loans, Management measures loss potential of the carrying value of loans. As described above, payments received on nonaccrual loans may be applied against the principal balance of the loans until such time as full collection of the remaining recorded balance is expected. Further, the carrying value of purchased loans includes fair value discounts assigned at the time of purchase under the provisions of FASB ASC 805, Business Combinations, and FASB ASC 310-30, Loans or Debt Securities with Deteriorated Credit Quality. The allowance for loan losses represents Management’s estimate of loan losses in excess of these reductions to the carrying value of loans within the loan portfolio.

The Company's allowance for loan losses is maintained at a level considered appropriate to provide for losses that can be estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall loan loss experience, the amount of past due, nonperforming and classified loans, the amount of non-indemnified purchased loans, recommendations of regulatory authorities, prevailing economic conditions and other factors. A portion of the allowance is individually allocated to impaired loans whose full collectability of principal is uncertain. Such allocations are determined by Management based on loan-by-loan analyses. The Company evaluates all loans with outstanding principal balances in excess of $500 thousand which are classified or on nonaccrual status and all “troubled debt restructured” loans for impairment. The remainder of the loan portfolio is collectively evaluated for impairment based in part on quantitative analyses of historical loan loss experience of loan portfolio segments to determine standard loss rates for each segment. The loss rate for each loan portfolio segment reflects both the historical loss experience during a look-back period and the loss emergence period. The loss rates are applied to segmented loan balances to allocate the allowance to the segments of the loan portfolio.

Purchased loans were recorded on the date of purchase at estimated fair value; fair value discounts include a component for estimated loan losses. The Company evaluates all nonaccrual purchased loans with outstanding principal balances in excess of $500 thousand for impairment; the impaired loan value is compared to the recorded investment in the loan, which has been reduced by the loan default discount estimated on the date of purchase. If Management’s impairment analysis determines the impaired loan value is less than the recorded investment in the purchased loan, an allocation of the allowance for loan losses is established for the deficiency. For all other purchased loan portfolio segments, Management applies the standard loss rates to the purchased loan portfolio segments to determine initial allocations of the allowance. Further, liquidating purchased consumer installment loans are evaluated separately by applying historical loss rates to forecasted liquidating principal balances to initially measure losses inherent in this portfolio segment. The initial allocations of the allowance to purchased loan portfolio segments are compared to loan default discounts ascribed to each segment. Management establishes allocations of the allowance for loan losses for any estimated deficiency.

The remainder of the allowance is considered to be unallocated. The unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but not reflected in the allocated allowance. The unallocated allowance addresses additional qualitative factors consistent with Management's analysis of the level of risks inherent in the loan portfolio, which are related to the risks of the Company's general lending activity. Included in the unallocated allowance is the risk of losses that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in loan chargeoff history (external factors). The primary external factor evaluated by the Company and the judgmental amount of unallocated reserve assigned by Management as of March 31, 2016 are economic and business conditions $1.3 million. Also included in the unallocated allowance is the risk of losses attributable to general attributes of the Company's loan portfolio and credit administration (internal factors). The internal factors evaluated by the Company and the judgmental amount of unallocated reserve assigned by Management are: loan review system $1.1 million, adequacy of lending Management and staff $1.2 million, concentrations of credit $2.4 million, and other factors.

Asset/Liability and Market Risk Management

Asset/liability management involves the evaluation, monitoring and management of interest rate risk, market risk, liquidity and funding. The fundamental objective of the Company's management of assets and liabilities is to maximize its economic value while maintaining adequate liquidity and a conservative level of interest rate risk.

Interest Rate Risk

Interest rate risk is a significant market risk affecting the Company. Many factors affect the Company’s exposure to interest rates, such as general economic and financial conditions, customer preferences, historical pricing relationships, and re-pricing characteristics of financial instruments. Assets and liabilities may mature or re-price at different times. Assets and liabilities may re-price at the same time but by different amounts. Short-term and long-term market interest rates may change by different amounts. The timing and amount of cash flows of various assets or liabilities may shorten or lengthen as interest rates change. In addition, the changing levels of interest rates may have an impact on loan demand, demand for various deposit products, credit losses, and other elements of earnings such as account analysis fees on commercial deposit accounts and correspondent bank service charges.

The Company’s earnings are affected not only by general economic conditions, but also by the monetary and fiscal policies of the U.S. and its agencies, particularly the Federal Reserve Board (the “FRB”). The monetary policies of the FRB can influence the overall growth of loans, investment securities, and deposits and the level of interest rates earned on assets and paid for liabilities. The nature and impact of future changes in monetary policies are generally not predictable.

The Federal Open Market Committee (“FOMC”) increased the target range for the federal funds rate to 1/4 to 1/2 percent on December 16, 2015. Subsequently, interest rates on intermediate-term and long-term United States Treasury obligations declined from January 1, 2016 through March 31, 2016. In this context, Management expects a high level of uncertainty in regard to interest rate levels in the immediate term, and Management’s most likely earnings forecast for the twelve months ending March 31, 2017 assumes market interest rates will either remain at relatively low levels or short-term rates will rise gradually.

In adjusting the Company's asset/liability position, Management attempts to manage interest rate risk while enhancing the net interest margin and net interest income. At times, depending on expected increases or decreases in general interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, Management may adjust the Company's interest rate risk position in order to manage its net interest margin and net interest income. The Company's results of operations and net portfolio values remain subject to changes in interest rates and to fluctuations in the difference between long and short-term interest rates.

The Company’s asset and liability position was slightly “asset sensitive” at March 31, 2016, depending on the interest rate assumptions applied to the simulation model employed by Management to measure interest rate risk. An “asset sensitive” position results in a slightly larger change in interest income than in interest expense resulting from application of assumed interest rate changes. Simulation estimates depend on, and will change with, the size and mix of the actual and projected balance sheet at the time of each simulation. Management’s interest rate risk management is currently biased toward stable or gradually increasing interest rates in the near-term and intermediate-term. Management continues to monitor the interest rate environment as well as economic conditions and other factors it deems relevant in managing the Company's exposure to interest rate risk.

The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted with the approval of the Company's Board of Directors.

Market Risk - Equity Markets

Equity price risk can affect the Company. As an example, any preferred or common stock holdings, as permitted by banking regulations, can fluctuate in value. Management regularly assesses the extent and duration of any declines in market value, the causes of such declines, the likelihood of a recovery in market value, and its intent to hold securities until a recovery in value occurs. Declines in value of preferred or common stock holdings that are deemed “other than temporary” could result in loss recognition in the Company's income statement.

Fluctuations in the Company's common stock price can impact the Company's financial results in several ways. First, the Company has regularly repurchased and retired its common stock; the market price paid to retire the Company's common stock can affect the level of the Company's shareholders' equity, cash flows and shares outstanding. Second, the Company's common stock price impacts the number of dilutive equivalent shares used to compute diluted earnings per share. Third, fluctuations in the Company's common stock price can motivate holders of options to purchase Company common stock through the exercise of such options thereby increasing the number of shares outstanding. Finally, the amount of compensation expense associated with share based compensation fluctuates with changes in and the volatility of the Company's common stock price.

Market Risk - Other

Market values of loan collateral can directly impact the level of loan chargeoffs and the provision for loan losses. The financial condition and liquidity of debtors issuing bonds and debtors whose mortgages or other obligations are securitized can directly impact the credit quality of the Company’s investment portfolio requiring the Company to recognize other than temporary impairment charges. Other types of market risk, such as foreign currency exchange risk and commodity price risk, are not significant in the normal course of the Company's business activities.

Liquidity and Funding

The objective of liquidity management is to manage cash flow and liquidity reserves so that they are adequate to fund the Company's operations and meet obligations and other commitments on a timely basis and at a reasonable cost. The Company achieves this objective through the selection of asset and liability maturity mixes that it believes best meet its needs. The Company's liquidity position is enhanced by its ability to raise additional funds as needed in the wholesale markets.

In recent years, the Company's deposit base has provided the majority of the Company's funding requirements. This relatively stable and low-cost source of funds, along with shareholders' equity, provided 98 percent of funding for average total assets in the first quarter 2016 and 97 percent in 2015. The stability of the Company’s funding from customer deposits is in part reliant on the confidence clients have in the Company. The Company places a very high priority in maintaining this confidence through conservative credit and capital management practices and by maintaining an appropriate level of liquidity reserves.

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing loans. The Company's investment securities portfolio provides a substantial secondary liquidity reserve. The Company held $2.9 billion in total investment securities at March 31, 2016. Under certain deposit, borrowing and other arrangements, the Company must hold and pledge investment securities as collateral. At March 31, 2016, such collateral requirements totaled approximately $712 million.

Liquidity risk can result from the mismatching of asset and liability cash flows, or from disruptions in the financial markets. The Company performs liquidity stress tests on a periodic basis to evaluate the sustainability of its liquidity. Under the stress testing, the Company assumes outflows of funds increase beyond expected levels. Measurement of such heightened outflows considers the composition of the Company’s deposit base, including any concentration of deposits, non-deposit funding such as short-term borrowings, and unfunded lending commitments. The Company evaluates its stock of highly liquid assets to meet the assumed higher levels of outflows. Highly liquid assets include cash and amounts due from other banks from daily transaction settlements, reduced by branch cash needs and Federal Reserve Bank reserve requirements, and investment securities based on regulatory risk-weighting guidelines. Based on the results of the most recent liquidity stress test, Management is satisfied with the liquidity condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period of reduced liquidity.

Management will monitor the Company’s cash levels throughout 2016. Loan demand from credit-worthy borrowers will be dictated by economic and competitive conditions. The Company aggressively solicits non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to changes in interest rates. The growth of these deposit balances is subject to heightened competition, the success of the Company's sales efforts, delivery of superior customer service, new regulations and market conditions. The Company does not aggressively solicit higher-costing time deposits; as a result, Management anticipates such deposits will decline. Changes in interest rates, most notably rising interest rates, could impact deposit volumes. Depending on economic conditions, interest rate levels, liquidity management and a variety of other conditions, deposit growth may be used to fund loans or purchase investment securities. However, due to possible volatility in economic conditions, competition and political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue subject to the Board's discretion and continuing evaluation of capital levels, earnings, asset quality and other factors.

Westamerica Bancorporation ("Parent Company") is a separate entity apart from Westamerica Bank (“Bank”) and must provide for its own liquidity. In addition to its operating expenses, the Parent Company is responsible for the payment of dividends declared for its shareholders, and interest and principal on any outstanding debt. Substantially all of the Parent Company's revenues are obtained from subsidiary dividends and service fees.

The Bank’s dividends paid to the Parent Company and proceeds from the exercise of stock options provided adequate cash flow for the Parent Company to pay shareholder dividends of $10 million in the first quarter 2016 and $39 million in 2015, and retire common stock in the amount of $5 million and $15 million, respectively. Payment of dividends to the Parent Company by the Bank is limited under California and Federal laws. The Company believes these regulatory dividend restrictions will not have an impact on the Parent Company's ability to meet its ongoing cash obligations.

Capital Resources

The Company has historically generated high levels of earnings, which provides a means of accumulating capital. The Company's net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 10.9% (annualized) in the first quarter 2016, 11.3% in 2015 and 11.6% in 2014. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of stock options was $2 million in the first quarter 2016 compared with $5 million in 2015 and $12 million in 2014.

The Company paid common dividends totaling $10 million in the first quarter 2016, $39 million in 2015 and $40 million in 2014, which represent dividends per common share of $0.39, $1.53 and $1.52, respectively. The Company's earnings have historically exceeded dividends paid to shareholders. The amount of earnings in excess of dividends provides the Company resources to finance growth and maintain appropriate levels of shareholders' equity. In the absence of profitable growth opportunities, the Company has repurchased and retired its common stock as another means to return earnings to shareholders. The Company repurchased and retired 130 thousand shares valued at $5 million in the first quarter 2016, 344 thousand shares valued at $15 million in 2015 and 1.0 million shares valued at $53 million in 2014.

The Company's primary capital resource is shareholders' equity, which was $539 million at March 31, 2016 compared with $532 million at December 31, 2015. The Company's ratio of equity to total assets was 10.37% at March 31, 2016 and 10.30% at December 31, 2015.

The Company performs capital stress tests on a periodic basis to evaluate the sustainability of its capital. Under the stress testing, the Company assumes various scenarios such as deteriorating economic and operating conditions, unanticipated asset devaluations, and significant operational lapses. The Company measures the impact of these scenarios on its earnings and capital. Based on the results of the most recent stress tests, Management is satisfied with the capital condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period of reduced earnings or a reduction in capital from unanticipated events and circumstances.

Capital to Risk-Adjusted Assets

On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for all banking organizations. The rule’s provisions which most affected the regulatory capital requirements of the Company and the Bank:

Introduced a new “Common Equity Tier 1” capital measurement,

Established higher minimum levels of capital,

Introduced a “capital conservation buffer,”

Increased the risk-weighting of certain assets, and

Established limits on the amount of deferred tax assets with any excess treated as a deduction from Tier 1 capital.

Under the final rule, a banking organization that is not subject to the “advanced approaches rule” may make a one-time election not to include most elements of Accumulated Other Comprehensive Income, including net-of-tax unrealized gains and losses on available for sale investment securities, in regulatory capital. Neither the Company nor the Bank are subject to the “advanced approaches rule” and made the election not to include most elements of Accumulated Other Comprehensive Income in regulatory capital.

Banking organizations that are not subject to the “advanced approaches rule” began complying with the final rule on January 1, 2015; on such date, the Company and the Bank became subject to the revised definitions of regulatory capital, the new minimum regulatory capital ratios, and various regulatory capital adjustments and deductions according to transition provisions and timelines. All banking organizations began calculating standardized total risk-weighted assets on January 1, 2015. The transition period for the capital conservation buffer for all banking organizations began on January 1, 2016 and will end January 1, 2019. Any bank subject to the rule which is unable to maintain its “capital conservation buffer” will be restricted in the payment of discretionary executive compensation and shareholder distributions, such as dividends and share repurchases.

- 49 -

The final rule did not supersede provisions of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) requiring federal banking agencies to take prompt corrective action (PCA) to resolve problems of insured depository institutions. The final rule revised the PCA thresholds to incorporate the higher minimum levels of capital, including the “common equity tier 1” ratio.

The capital ratios for the Company and the Bank under the new capital framework are presented in the table below.

							Transitional Minimum Regulatory Requirement			Minimum Regulatory Requirement			Well-capitalized by Regulatory Definition Under FDICIA
	At March 31, 2016						Effective			Effective			Effective

The Company and the Bank routinely project capital levels by analyzing forecasted earnings, credit quality, securities valuations, shareholder dividends, asset volumes, share repurchase activity, stock option exercise proceeds, and other factors. Based on current capital projections, the Company and the Bank expect to maintain regulatory capital levels exceeding the highest effective regulatory standard and pay quarterly dividends to shareholders. No assurance can be given that changes in capital management plans will not occur.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Credit risk and interest rate risk are the most significant market risks affecting the Company, and equity price risk can also affect the Company’s financial results. These risks are described in the preceding sections regarding “Loan Portfolio Credit Risk,” and “Asset/Liability and Market Risk Management.” Other types of market risk, such as foreign currency exchange risk and commodity price risk, are not significant in the normal course of the Company’s business activities.
