Discontinued Operations During the first quarter of 2015, the Company ceased operations of GMB due to increasing regulatory compliance costs and in order to focus on activities that provide recurring revenue. The net carrying value of the assets and liabilities of GMB was $0.8 million and were transferred to the parent Company at the end of the first quarter of 2015. The results of operations for GMB have been retrospectively presented as discontinued operations in all periods presented. The table below presents the results of the discontinued operations of GMB for the years ended December 31, 2015 and 2014.

There were no security transfers between the AFS and HTM categories in 2016. The Company believes the HTM category is more consistent with the Company’s intent for these securities. Transfers of securities from AFS to HTM were made at fair value at the time of transfer. The unamortized portion of the $8.8 million unrealized holding gain at the time of transfer is retained in AOCI and in the carrying value of HTM securities. Accordingly, the balance of HTM securities in the “Amortized cost” column in the table above includes net unamortized unrealized gains of $5.1 million and $6.9 million at December 31, 2016 and 2015, respectively. Such amounts are amortized over the remaining life of the securities. Proceeds from the sale of investments and the gain (loss) recognized on securities sold or called are summarized as follows: For the year ended December 31, (in thousands) 2016 2015 2014 Proceeds $ - $ - $ Gains Losses The amortized cost and estimated fair value of investments in debt securities at December 31, 2016, by contractual maturity are shown below.

Changes in interest rates and market liquidity may cause adverse fluctuations in the market price of securities resulting in temporary unrealized losses. In reviewing the realizable value of its securities in a loss position, the Company considered the following factors: (1) the length of time and extent to which the market had been less than cost; (2) the financial condition and near-term prospects of the issuer; (3) investment downgrades by rating agencies; and (4) whether it is more likely than not that the Company will have to sell the security before a recovery in value. When it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the security, and the fair value of the investment security is less than its amortized cost, an other-than-temporary impairment is recognized in earnings. For debt securities that are considered other-than temporarily impaired and that the Company does not intend to sell and will not be required to sell prior to recovery of the amortized cost basis, OTTI is recognized. OTTI is separated into the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between a security’s amortized cost basis and the discounted present value of expected future cash flows. The amount due to all other factors is recognized in OCI. There were 165 and 168 securities in the tables below at December 31, 2016 and 2015, respectively, in an unrealized loss position.

The purpose of the FHLB investment relates to maintenance of a borrowing base with the FHLB. FHLB stock holdings are largely dependent upon the Company’s liquidity position. To the extent the need for wholesale funding increases or decreases, the Company may purchase additional or sell excess FHLB stock, respectively. The Company evaluates impairment in this investment based on the ultimate recoverability of the par value and at December 31, 2016 and 2015, did not consider the investment to be other-than-temporarily impaired.

Loans	4. Loans The following disclosure reports the Company’s loan portfolio segments and classes. Segments are groupings of similar loans at a level which the Company has adopted systematic methods of documentation for determining its allowance for loan and credit losses. Classes are a disaggregation of the portfolio segments. The Company’s loan portfolio segments are: · Commercial loans – Commercial loans consist of loans to small and medium-sized businesses in a wide variety of industries. The Bank’s areas of emphasis in commercial lending include, but are not limited to, loans to wholesalers, manufacturers, municipalities, and construction and business services companies. Commercial loans are generally collateralized by inventory, accounts receivable, equipment, real estate and other commercial assets, and may be supported by other credit enhancements such as personal guarantees. Risk arises primarily due to a difference between expected and actual cash flows of the borrowers. However, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrowers’ ability to collect amounts due from its customers. · Real estate - mortgage loans – Real estate mortgage loans include various types of loans for which the Company holds real property as collateral. Commercial real estate lending activity is typically restricted to owner-occupied properties or to investor properties that are owned by customers with a current banking relationship. The primary risks of real estate mortgage loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate mortgage loan unprofitable. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. · Construction & land – The Company originates loans to finance construction projects including one- to four-family residences, multifamily residences, commercial office, senior housing, and industrial projects. Residential construction loans are due upon the sale of the completed project and are generally collateralized by first liens on the real estate and have floating interest rates. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, governmental regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans. Adverse economic conditions may negatively impact the real estate market which could affect the borrowers’ ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. The Company also originates loans for the acquisition and future development of land for residential building projects, as well as finished lots prepared to enter the construction phase. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral. · Consumer loans – The Company provides a broad range of consumer loans to customers, including personal lines of credit, home equity loans, residential mortgage loans and automobile loans. Repayment of these loans is dependent on the borrowers’ ability to pay and the fair value of the underlying collateral. · Other loans – Other loans include lending products, such as taxable and tax-exempt leasing, not defined as commercial, real estate, acquisition and development, construction, or consumer loans. The loan portfolio segments at December 31, 2016 and 2015 were as follows: December 31, (in thousands) 2016 2015 Commercial $ $ Real estate - mortgage Construction & land Consumer Other Loans held for investment Allowance for loan losses Unearned net loan fees Total net loans $ $ The Company routinely acquires participating interests in loans originated by other banks. At December 31, 2016 and 2015, overdraft demand deposits totaling $0.6 million and $0.2 million, respectively, were reclassified from deposits to loans. The Company maintains a loan review program independent of the lending function that is designed to reduce and control risk in lending. It includes the continuous monitoring of lending activities with respect to underwriting and processing new loans, preventing insider abuse and timely follow-up and corrective action for loans showing signs of deterioration in quality. The Company also has a systematic process to evaluate individual loans and pools of loans within our loan portfolio. The Company maintains a loan grading system whereby each loan is assigned a grade between 1 and 8, with 1 representing the highest quality credit, 7 representing a nonaccrual loan where collection or liquidation in full is highly questionable and improbable, and 8 representing a loss that has been or will be charged-off. Grades are assigned based upon the degree of risk associated with repayment of a loan in the normal course of business pursuant to the original terms. Loans that are graded 5 or lower are categorized as non-classified credits while loans graded 6 and higher are categorized as classified credits. Loan grade changes are evaluated on a monthly basis. Loans above a certain dollar amount that are adversely graded are reported to the Special Assets Group manager and the Chief Credit Officer along with current financial information, a collateral analysis and an action plan. The loan portfolio showing total non-classified and classified balances by loan class at December 31, 2016 and 2015 is summarized below: At December 31, 2016 (in thousands) Non-classified Classified Total Commercial Manufacturing $ $ $ Finance and insurance Health care Real estate services Construction Public administration Other Real estate - mortgage Residential & commercial owner-occupied Residential & commercial investor Construction & land Consumer Other Total loans held for investment $ $ $ Unearned net loan fees Net loans held for investment $ At December 31, 2015 (in thousands) Non-classified Classified Total Commercial Manufacturing $ $ $ Finance and insurance Health care Real estate services Construction Public administration Other Real estate - mortgage Residential & commercial owner-occupied Residential & commercial investor Other - Construction & land Consumer Other Total loans held for investment $ $ $ Unearned net loan fees Net loans held for investment $ Transactions in the ALL by segment for the years ended December 31, 2016 and 2015 are summarized below: For the year ended December 31, (in thousands) 2016 2015 Allowance for loan losses, beginning of period Commercial $ $ Real estate - mortgage Construction & land Consumer Other Unallocated Total Provision Commercial $ $ Real estate - mortgage Construction & land Consumer Other Unallocated Total Charge-offs Commercial $ $ Real estate - mortgage - Construction & land - Consumer Other - Total Recoveries Commercial $ $ Real estate - mortgage Construction & land Consumer Other - Total Allowance for loan losses, end of period Commercial $ $ Real estate - mortgage Construction & land Consumer Other Unallocated Total $ $ The Company estimates the ALL in accordance with ASC 310 for purposes of evaluating loan impairment on a loan-by-loan basis and ASC 450 for purposes of collectively evaluating loan impairment by grouping loans with common risk characteristics (i.e. risk classification, past-due status, type of loan, and collateral). The ALL is comprised of the following components: · Specific Reserves – The Company continuously evaluates its reserve for loan losses to maintain an adequate level to absorb loan losses incurred in the loan portfolio. Reserves on loans identified as impaired, including troubled debt restructurings, are based on discounted expected cash flows using the loan’s initial effective interest rate, the observable market value of the loan or the fair value of the collateral for certain collateral-dependent loans. The fair value of the collateral is determined in accordance with ASC 820. Loans are considered to be impaired in accordance with the provisions of ASC 310, when it is probable that all amounts due in accordance with the contractual terms will not be collected. Factors contributing to the determination of specific reserves include the financial condition of the borrower, changes in the value of pledged collateral and general economic conditions. Troubled debt restructurings meet the definition of an impaired loan under ASC 310 and therefore, troubled debt restructurings are subject to impairment evaluation on a loan-by-loan basis. For collateral dependent loans that have been specifically identified as impaired, the Company measures fair value based on third-party appraisals, adjusted for estimated costs to sell the property. Upon impairment, the Company will obtain a new appraisal if one had not been previously obtained in the last 12 months. For credits over $2.0 million, the Company engages an additional third-party appraiser to review the appraisal. For credits under $2.0 million, the Company’s internal appraisal department reviews the appraisal. All appraisals are reviewed for adherence to regulations and mathematical accuracy reasonableness based on recent sales transactions that may have occurred subsequent to or right at the time of the appraisal. Based on this analysis the appraised value may be adjusted downward if there is evidence that the appraised value may not be indicative of fair value. Each appraisal is updated on an annual basis, either through a new appraisal or through the Company’s comprehensive internal review process. Values are reviewed and monitored internally and fair value is re-assessed at least quarterly or more frequently when events or circumstances occur that indicate a change in fair value. · General Reserves – General reserves are considered part of the allocated portion of the allowance. The Company uses a comprehensive loan grading process for our loan portfolios. Based on this process, a loss factor is assigned to each pool of graded loans. A combination of loss experience and external loss data is used in determining the appropriate loss factor. This estimate represents the probable incurred losses within the portfolio. In evaluating the adequacy of the ALL, management considers historical losses (Migration), as well as other factors including changes in: · Lending policies and procedures · National and local economic and business conditions and developments · Nature and volume of portfolio · Trends of the volume and severity of past-due and classified loans · Trends in the volume of nonaccrual loans, troubled debt restructurings, and other loan modifications · Credit concentrations Troubled debt restructurings have a direct impact on the allowance to the extent a loss has been recognized in relation to the loan modified. This is consistent with the Company’s consideration of Migration in determining general reserves. The aforementioned factors enable management to recognize environmental conditions contributing to incurred losses in the portfolio, which have not yet manifested in Migration. Management believes Migration history adequately captures a great percentage of probable incurred losses within the portfolio. In addition to the allocated reserve for graded loans, a portion of the allowance is determined by segmenting the portfolio into product groupings with similar risk characteristics. Part of the segmentation involves assigning increased reserve factors to those lending activities deemed higher-risk such as leverage-financings, unsecured loans, certain loans lacking personal guarantees, senior housing, speculative residential construction and multifamily loans. · Unallocated Reserves – The unallocated reserve, which is judgmentally determined, is maintained to recognize the imprecision in estimating and measuring loss when evaluating reserves for individual loans or pools of loans. The unallocated reserve consists of a missed grade component that is intended to capture the inherent risk that certain loans may be assigned an incorrect loan grade. In assessing the reasonableness of management’s assumptions, consideration is given to select peer ratios, industry standards and directional consistency of the ALL. Ratio analysis highlights divergent trends in the relationship of the ALL to nonaccrual loans, to total loans and to historical charge-offs. Although these comparisons can be helpful as a supplement to assess reasonableness of management assumptions, they are not, by themselves, sufficient basis for determining the adequacy of the ALL. While management utilizes its best judgment and information available, the ultimate adequacy of the allowance is dependent upon a variety of factors beyond the Company’s control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications.

Borrowed Funds Securities sold under agreements to repurchase at December 31, 2016 and 2015 are summarized as follows: At December 31, (in thousands) 2016 2015 Securities sold under agreements to repurchase (principally mortgage-backed securities with an estimated fair value of $28,192 and $49,882 in 2016 and 2015, respectively $ $ The Company enters into sales of securities under agreements to repurchase. The amounts received under these agreements represent short-term borrowings and are reflected as a liability in the consolidated balance sheets. The securities underlying these agreements are included in investment securities in the consolidated balance sheets. The Company has no control over the market value of the securities, which fluctuates due to market conditions. However, the Company is obligated to promptly transfer additional securities if the market value of the securities falls below the repurchase agreement price. The Company manages this risk by maintaining an unpledged securities portfolio that it believes is sufficient to cover a decline in the market value of the securities sold under agreements to repurchase. Securities sold under agreements to repurchase averaged $46.0 million and $57.3 million during 2016 and 2015, respectively. The maximum amounts outstanding at any month-end during 2016 and 2015 were $71.0 million and $68.6 million, respectively. At December 31, 2016 and 2015, the weighted‑average interest rate was 0.07% and 0.06%, respectively. All securities sold under agreements to repurchase had a maturity date of less than three months. The Company has a revolving Line of Credit (LOC) agreement with an aggregate principal sum of up to $20.0 million bearing interest at 1-month LIBOR plus 225 basis points (2.25%). The Company pays a quarterly commitment fee of 0.35% per annum on the unused portion of the LOC. The LOC matures in May 2017, at which time any outstanding amounts are due and payable. The LOC is used for general corporate purposes and backup liquidity. Although the credit facility is unsecured, the Company has agreed not to sell, pledge or transfer any part of its right, title or interest in the Bank. At December 31, 2016 and 2015, there was no amount outstanding on the revolving LOC. The Company has a line of credit with the FHLB with a rolling one-year term that matures every July with automatic renewals unless canceled. There was $106.2 million and $132.0 million outstanding on the FHLB line of credit at December 31, 2016 and 2015. The average FHLB line of credit balance was $82.8 million and $61.1 million during 2016 and 2015, respectively. The line of credit is collateralized by either qualifying loans or investment securities not otherwise pledged as collateral. At December 31, 2016, the FHLB line of credit was collateralized by loans of $861.0 million with a lending value of $598.5 million. At December 31, 2015, the FHLB line of credit was collateralized by loans of $867.4 million with a lending value of $591.2 million. The variable-rate on the line of credit was 0.72% and 0.48% at December 31, 2016 and 2015, respectively. The Company has approved federal fund purchase lines with eight banks with an aggregate credit line of $170.0 million. No amounts were outstanding on the federal funds purchase lines at the end of either 2016 or 2015.

For further discussion of the interest rate swaps and the corresponding terms, see Note 10 - Derivatives. In September 2003, the Company created a wholly owned trust, CoBiz Statutory Trust I, formed under the laws of the State of Connecticut (the Statutory Trust). The Statutory Trust issued $20.0 million of trust preferred securities bearing an interest rate based on a spread above three-month LIBOR. Simultaneously with the issuance, the Company purchased a minority interest in the Statutory Trust for $0.6 million. The Statutory Trust invested the proceeds thereof in $20.6 million of junior subordinated debentures of CoBiz that also bear an interest rate based on a spread above three‑month LIBOR. The securities and junior subordinated debentures provide cumulative distributions at a floating rate that is reset each quarter on March 17, June 17, September 17 and December 17. The junior subordinated debentures will mature and the capital securities must be redeemed on September 17, 2033, which may be shortened to any quarterly distribution date, if certain conditions are met (including the Company having received prior approval from the Federal Reserve and any other required regulatory approvals) and notice is given at least 30 and not more than 60 days prior to the redemption date. In May 2004, the Company created a wholly owned trust, CoBiz Capital Trust II, formed under the laws of the State of Delaware (the Capital Trust II). The Capital Trust II issued $30.0 million of trust preferred securities bearing an interest rate based on a spread above three-month LIBOR. Simultaneously with the issuance, the Company purchased a minority interest in the Capital Trust II for $0.9 million. The Capital Trust II invested the proceeds thereof in $30.9 million of junior subordinated debentures of CoBiz that also bear an interest rate based on a spread above three-month LIBOR. The securities and junior subordinated debentures provide cumulative distributions at a floating rate that is reset each quarter on January 23, April 23, July 23 and October 23. The junior subordinated debentures will mature and the capital securities must be redeemed no later than July 23, 2034, if certain conditions are met (including the Company having received prior approval from the Federal Reserve and any other required regulatory approvals). In August 2005, the Company created a wholly owned trust, CoBiz Capital Trust III, formed under the laws of the State of Delaware (the Capital Trust III). The Capital Trust III issued $20.0 million of trust preferred securities bearing an interest rate based on a spread above three-month LIBOR. Simultaneously with the issuance, the Company purchased a minority interest in the Capital Trust III for $0.6 million. The Capital Trust III invested the proceeds thereof in $20.6 million of junior subordinated debentures of CoBiz that also bear an interest rate based on a spread above three‑month LIBOR. The securities and junior subordinated debentures provide cumulative distributions at a floating rate that is reset each quarter on March 30, June 30, September 30 and December 30. The junior subordinated debentures will mature and the capital securities must be redeemed no later than September 30, 2035, if certain conditions are met (including the Company having received prior approval from the Federal Reserve and any other required regulatory approvals). The Company records the distributions of the junior subordinated debentures in interest expense on the consolidated statements of income. All of the outstanding junior subordinated debentures may be prepaid if certain events occur, including a change in tax status or regulatory capital treatment of trust preferred securities. In each case, redemption will be made at par, plus the accrued and unpaid distributions thereon through the redemption date. The Basel III capital rules contain a provision that preserves the current capital treatment of trust preferred securities issued by bank holding companies with less than $15 billion in total assets. Although the accounts of the Statutory Trust, Capital Trust II and Capital Trust III are not included in the Company’s consolidated financial statements, $70.0 million in trust preferred securities issued by the trusts are included in Common equity Tier 1 capital for regulatory purposes as grandfathered under Basel III. See Note 17 – Regulatory Matters. In June 2015, the Company completed an offering of $60.0 million of unsecured 5.625% Fixed-to-Floating Rate Subordinated Notes (Notes) due on June 25, 2030. The Notes bear a 5.625% annual fixed-rate through June 25, 2025 and thereafter an annual floating rate equal to three-month LIBOR plus 317 basis points (3.17%). The Notes contain a call option that allows the Company to repay the Notes prior to their contractual maturity. The call option is available on June 25, 2025 and quarterly thereafter at 100% of the principal amount. Proceeds, net of an original discount and debt issuance costs of $1.1 million, were $58.9 million. Debt issuance costs incurred in conjunction with the offering were $0.3 million. The Notes have an effective interest rate of 5.85%. The Company has adopted ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30), that requires debt issuance costs to be reported as a direct deduction from the face of the note and not as a deferred charge. The discount and related debt issuance costs will be amortized into interest expense using the interest method over a 10-year term to the first call date.

Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and unknown cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable-rate loan assets and variable-rate borrowings. The Company also enters into derivative financial instruments to protect against adverse changes in fair value on fixed-rate loans. The Company’s objective in using derivatives is to minimize the impact of interest rate fluctuations on the Company’s net interest income. To accomplish this objective, the Company uses interest-rate swaps as part of its cash flow hedging strategy. The Company also offers an interest rate hedge program that includes various derivative products, including swaps, to assist its customers in managing their interest rate risk profile . In order to eliminate the interest-rate risk associated with offering these products, the Company enters into derivative contracts with third parties to offset the customer contracts. These customer accommodation interest rate swap contracts are not designated as hedging instruments. The Company has also expanded its product offering by adding international banking products, which exposes the Company to foreign exchange risk. The Company utilizes foreign exchange forward contracts to manage the risk associated with fluctuation in foreign exchange rates. The Company has agreements with its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. Also, the Company has agreements with certain of its derivative counterparties that contain a provision where if the Bank fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. At December 31, 2016, the fair value of derivatives in a net liability position, including accrued interest but excluding any adjustment for nonperformance risk, related to these agreements was $9.5 million. The Company has minimum collateral posting thresholds with certain of its derivative counterparties and has posted collateral of $9.7 million against its obligations under these agreements. At December 31, 2016, the Company was not in default with any of its debt or capitalization covenants. The table below presents the fair value of the Company’s derivative financial instruments as well as the classification within the consolidated balance sheets.

During the first quarter of 2016, the Company terminated five interest rate swaps with a notional value of $75.0 million that had fixed the interest rate on a portion of its 1-month LIBOR loan portfolio. Upon termination, the Company had an unrealized gain of $1.3 million in AOCI. The unrealized gain will continue to be reported in AOCI, and will be reclassified to interest income over a period of three years. In October 2016, the Company entered into two interest rate swaps to hedge the risk of changes in cash flow on its LIBOR-based loan portfolio. The interest rate swaps have a weighted average term of six years and have a combined notional value of $100.0 million. The Company will pay a variable rate based on 1-month LIBOR and receive a weighted average fixed-rate of 1.23%. For hedges of the Company’s variable-rate borrowings, interest-rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments. The Company has executed a series of interest-rate swap transactions in order to fix the effective interest rate for payments due on its junior subordinated debentures with the objective of reducing the Company’s exposure to adverse changes in cash flows relating to payments on its LIBOR-based floating rate debt. Select critical terms of the cash flow hedges are as follows: (in thousands) Notional Fixed-rate Termination date Hedged item - Junior subordinated debentures issued by: CoBiz Statutory Trust I $ 20,000 % March 17, 2022 CoBiz Capital Trust II $ 30,000 % April 23, 2020 CoBiz Capital Trust III $ 20,000 % March 30, 2024 Based on the Company’s ongoing assessments (including at inception of the hedging relationship), it is probable that there will be sufficient variable interest payments through the maturity date of the swaps. The Company also monitors the risk of counterparty default on an ongoing basis. The Company uses a regression analysis and the “Hypothetical Derivative” method described in ASC 815 for both prospective and retrospective assessments of hedge effectiveness on a quarterly basis. The Company also uses the Hypothetical Derivative methodology to measure hedge ineffectiveness each period. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in AOCI and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company’s derivatives did not have any hedge ineffectiveness recognized in earnings during the years ended December 31, 2016, 2015 and 2014. Amounts reported in AOCI related to derivatives will be reclassified to interest income as interest payments are received/paid on the Company’s variable-rate assets. Payments received/paid on variable-rate liabilities will be reclassified to interest expense. During the next 12 months, the Company estimates that $0.8 million and $1.3 million will be reclassified as an increase to interest income and interest expense, respectively. Fair Value Hedges of Fixed-Rate Assets – The Company is exposed to changes in the fair value of certain of its fixed-rate assets due to changes in benchmark interest rates based on LIBOR. The Company uses interest rate swaps to manage its exposure to changes in fair value on certain fixed-rate loans. Interest rate swaps designated as fair value hedges involve the receipt of variable-rate payments from a counterparty in exchange for the Company’s fixed-rate payments over the life of the agreements without the exchange of the underlying notional amount. Certain interest-rate swaps met the criteria to qualify for the shortcut method of accounting. Under the shortcut method of accounting no ineffectiveness is assumed. For interest-rate swaps not accounted for under the shortcut method, the Company performs ongoing retrospective and prospective effectiveness assessments (including at inception) using a regression analysis to compare periodic changes in fair value of the swaps to periodic changes in fair value of the fixed-rate loans attributable to changes in the benchmark interest rate. At December 31, 2016, the Company had interest rate swaps with a notional amount of $55.4 million used to hedge the change in the fair value of ten commercial loans. At December 31, 2015, the Company had interest rate swaps with a notional amount of $55.1 million used to hedge the change in the fair value of nine commercial loans. For derivatives that are designated and qualify as fair value hedges that are not accounted for under the shortcut method, the gain or loss on the derivative as well as the gain or loss on the hedged item attributable to the hedged risk are recognized in earnings. The net amount recognized in noninterest expense during the years ended December 31, 2016, 2015 and 2014 representing hedge ineffectiveness was immaterial. Non-designated Hedges — Derivatives not designated as hedges are not speculative and primarily result from a service the Company provides to its customers. The Company executes interest-rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest-rate swaps are simultaneously hedged by offsetting interest-rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest-rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. At December 31, 2016, the Company had 96 interest-rate swaps with an aggregate notional amount of $247.6 million related to this program. Gains and losses arising from changes in the fair value of these swaps are included in “Other income” in the consolidated statement of operations. During the years ending December 31, 2016, 2015 and 2014, the Company recorded immaterial gains and losses. The Company’s product offerings also include international banking products that create foreign currency exchange-rate risk exposure. At December 31, 2016, the Company’s foreign currency held include the British pound; Euro; Swiss franc; Mexican peso; Japanese yen; and Australian, Canadian and New Zealand dollars. In order to economically reduce the risk associated with the fluctuation of foreign exchange rates, the Company utilizes short-term foreign exchange forward contracts to lock in exchange rates so the gain or loss on the forward contracts approximately offsets the transaction gain or loss. These contracts are not designated as hedging instruments. Ineffectiveness in the economic hedging relationship may occur as the foreign currency holdings are revalued based upon changes in the currency’s spot rate, while the forward contracts are revalued using the currency’s forward rates. Forward contracts in gain positions are recorded at fair value in ‘other’ assets, while contracts in loss positions are recorded in ‘other’ liabilities in the consolidated balance sheets. Net changes in the fair value of the forward contracts are recognized through earnings, and are included in “Other income” in the consolidated statement of operations. At December 31, 2016, the Company had entered into forward contracts with a notional amount of $4.5 million that mature in the first half of 2016. During the years ending December 31, 2016, 2015 and 2014, the Company recorded immaterial gains and losses.

Income Taxes The components of consolidated income tax expense (benefit) for the years ended December 31, 2016, 2015 and 2014 are as follows: For the year ended December 31, (in thousands) 2016 2015 2014 Current tax provision: Federal tax $ $ $ State tax Total current tax provision Deferred tax provision (benefit): Federal tax State tax Net operating loss carryforward - Total deferred tax provision (benefit) Provision for income taxes $ $ $ Provision (benefit) related to discontinued operations $ - $ $ The primary component of deferred tax expense during 2016 was attributable to timing differences in the allowance for loan and credit losses. At December 31, 2016, the Company did not have any net operating loss carryforwards from any tax jurisdiction. The deferred tax provision (benefit) relating to discontinued operations includes deferred tax expense of $0.8 million and $0.0 million for the years ended December 31, 2015, and 2014, respectively. A deferred tax asset or liability is recognized for the tax consequences of temporary differences in the recognition of revenue and expense, and unrealized gains and losses, for financial and tax reporting purposes. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some or all of the deferred tax assets may not be realized. The Company conducted an analysis to assess the need of a valuation allowance at December 31, 2016, 2015 and 2014. As part of this assessment, all available evidence, including both positive and negative, was considered to determine whether based on the weight of such evidence, a valuation allowance for deferred tax assets was needed. In accordance with ASC Topic 740-10, Income Taxes (ASC 740), a valuation allowance is deemed to be needed when, based on the weight of the available evidence, it is more likely than not (a likelihood of more than 50%) that some portion or all of a deferred tax asset will not be realized. The future realization of the tax benefit depends on the existence of sufficient taxable income within the carryback and carryforward periods. At December 31, 2016 and 2015, the Company was in a positive three-year cumulative income position, had availability in its carryback years to absorb potential deferred income tax asset reversals and had financial forecasts of pre-tax income that were sufficient to absorb the deferred income tax assets. Accordingly, the Company determined that a valuation allowance was not warranted at December 31, 2016 and 2015. In the first quarter of 2016, the Company adopted ASU 2016-09, which requires the Company to recognize all excess tax benefits or tax deficiencies through the income statement as income tax expense/benefit. Upon exercise or vesting of a share-based award, an excess tax benefit will be recognized if the tax deduction exceeds the compensation cost that was previously recorded for financial statement purposes. Under previous GAAP, any excess tax benefits were recognized in additional paid-in capital to offset current-period and subsequent-period tax deficiencies. A tax benefit of $0.3 million was recorded during the year ended December 31, 2016 as a result of share awards vested/exercised during the year. The net change in deferred taxes related to investment securities available for sale and cash flow hedges is included in other comprehensive income. The temporary differences, tax effected, which give rise to the Company’s net deferred tax assets at December 31, 2016 and 2015 are as follows: At December 31, (in thousands) 2016 2015 Deferred tax assets: Allowance for loan and credit losses $ $ Intangible assets Other real estate owned Deferred loan fees Other accrued liabilities Stock-based compensation Interest on nonaccrual loans Employee bonus Other Total deferred tax assets $ $ Deferred tax liabilities: Deferred initial direct loan costs $ $ Property, plant and equipment - Prepaid assets FHLB stock dividends Investment securities and derivatives Total deferred tax liabilities $ $ Net deferred tax assets $ $ A reconciliation of income tax expense at the statutory rate to the Company’s actual income tax expense for the years ended December 31, 2016, 2015 and 2014 is shown below: For the year ended December 31, (in thousands) 2016 2015 2014 Computed at the statutory rate (35%) $ $ $ Increase (decrease) resulting from: State income taxes - net of federal income tax effect Tax exempt income Nondeductible compensation Meals and entertainment Excess tax benefit on stock compensation - - Other - net Actual tax provision $ $ $ ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. At December 31, 2016 and 2015 the Company did not have any unrecognized benefits. Penalties and interest are classified as income tax expense when incurred. There were no interest and penalties accrued during the year ended December 31, 2016 and 2015.

On September 8, 2011, the Company entered into and consummated the transactions contemplated by a Securities Purchase Agreement (Purchase Agreement) with the U.S. Secretary of the Treasury (Treasury) under the Small Business Lending Fund (SBLF), a $30 billion fund established under the Small Business Jobs Act of 2010 that was designed to encourage lending to small businesses by providing capital to qualified community banks with assets of less than $10 billion. Pursuant to the Purchase Agreement, the Company issued and sold to the Treasury, for an aggregate purchase price of $57.4 million, 57,366 shares of the Company’s Series C Preferred Stock, par value $0.01 per share, having a liquidation value of $1,000 per share. On July 22, 2015, all Series C Preferred Stock was redeemed at the liquidation value of $1,000 per share plus accrued dividends with an aggregate payment of $57.4 million. Warrant — The Company issued a warrant on December 19, 2008 as part of the Company’s participation in the TARP Capital Purchase program. The warrant has a 10-year term and allows for the purchase of 895,968 shares of the Company’s common stock at an exercise price of $10.79 per share. Dividends — The Company’s ability to pay dividends to its shareholders is generally dependent upon the payment of dividends by the Bank to the Parent. The Bank cannot pay dividends to the extent it would be deemed undercapitalized by the FDIC after making such dividend. At December 31, 2016, the Bank was not otherwise restricted in its ability to pay a dividend to the Parent as its earnings in the current and prior two years, net of dividends paid during those years, was positive. Dividends on the Company’s capital stock (common and preferred stock, if any) are prohibited under the terms of the junior subordinated debenture agreements (see Note 9 – Long-Term Debt) if the Company is in continuous default on its payment obligations to the capital trusts, has elected to defer interest payments on the debentures or extends the interest payment period. At December 31, 2016, the Company was not in default on any of the junior subordinated debenture issuances. Dividends declared per common share for the years ended December 31, 2016, 2015 and 2014 were $0.19, $0.17 and $0.15, respectively. Dividends on the Series C Preferred Stock for the years ended December 31, 2015 and 2014 were $0.3 million and $0.6 million, respectively.

Earnings per Common Share and Dividends Declared per Common Share	14. Earnings per Common Share Earnings per common share is calculated based on the two-class method prescribed in ASC 260, Earnings per Share . The two-class method is an allocation of undistributed earnings to common stock and securities that participate in dividends with common stock. The Company’s restricted stock awards are considered participating securities as the unvested awards have non-forfeitable rights to dividends, paid or unpaid, on unvested awards. The impact of participating securities is included in the common shareholder basic earnings per share for all periods presented as the Company had positive earnings in those periods. Income available to common shareholders together with weighted average shares outstanding used in the calculation of basic and diluted earnings per common share are as follows: Year ended December 31, (in thousands, except share amounts) 2016 2015 2014 Net income from continuing operations $ $ $ Net income (loss) from discontinued operations - Net income Preferred stock dividends - Net income available to common shareholders Dividends and undistributed earnings allocated to participating securities Earnings allocated to common shares (1) $ $ $ Weighted average common shares - issued Average unvested restricted share awards Weighted average common shares outstanding - basic Effect of dilutive stock options, awards and warrants outstanding Weighted average common shares outstanding - diluted Weighted average antidilutive securities outstanding (2) Earnings per common share: Basic - continuing $ $ $ Diluted - continuing $ $ $ Basic - discontinued $ - $ $ Diluted - discontinued $ - $ $ Basic $ $ $ Diluted $ $ $ (1) Earnings allocated to common shareholders for basic EPS under the two-class method may differ from earnings allocated for diluted EPS when use of the treasury method results in greater dilution than the two-class method.

Employee Benefit And Stock Compensation Plans	15. Employee Benefit and Stock Compensation Plans Stock Options and Awards — The Company has adopted an equity plan to reward and provide long-term incentives for directors and key employees of the Company. The term of all options issued may not exceed 10 years. The Company issues options and awards with a service vesting requirement, which is typically a three-year period. The Company issues new shares upon exercise of a stock option award. The 2005 Equity Incentive Plan (the 2005 Plan) originally authorized the issuance 1,250,000 shares of common stock. The 2005 Plan was amended at the May 15, 2008 Annual Shareholders Meeting to increase the authorized shares available under the plan to 2,750,000 shares of common stock and shares available for restricted stock awards was increased by 250,000 shares to 500,000 shares. The 2005 Plan was further amended at the May 20, 2010 Annual Shareholders Meeting to increase the authorized shares available under the plan to 3,750,000 shares of common stock and shares available for restricted stock awards was increased by 1,500,000 shares to 2,000,000 shares. The 2005 Plan was amended at the May 15, 2014 Annual Shareholders Meeting to increase the authorized shares available to 5,250,000 and remove the restriction on the number of restricted stock awards. Under the 2005 Plan, the Compensation Committee of the Company has the authority to determine the identity of the key employees, consultants and directors who shall be granted options; the option price, which shall not be less than 85% of the fair market value of the common stock on the date of grant; and the manner and times at which the options shall be exercisable. Shares available for grant under the 2005 Plan at December 31, 2016, totaled 2,421,120. During 2016, 2015 and 2014, the Company recognized compensation expense from continuing operations of $3.2 million, $3.3 million and $3.1 million, respectively, for stock-based compensation awards for which the requisite service was rendered during the year. Pursuant to the adoption of ASU 2016-09 in 2016, the Company has elected to recognize forfeitures as they occur. The Company recognized an income tax benefit of $1.2 million on compensation expense for 2016, 2015 and 2014. In addition, the Company recognized excess tax benefits of $0.3 million as a reduction to income tax in 2016. ASC 718 requires the Company to select a valuation technique that meets the measurement criteria set forth in the standard. Valuation techniques that meet the criteria for estimating the fair values of employee stock options include a lattice model and a closed-form model (for example, the Black-Scholes formula). The Company uses the Black-Scholes option pricing model (Black-Scholes) to estimate the fair value of stock options. Restricted stock award fair values are based on the closing price of the Company stock on the award date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield in effect at the time of grant. The expected term of options granted is based on the options’ vesting schedule and the Company’s historical exercise patterns for different employee groups and represents the period of time that options granted are expected to be outstanding. Expected volatilities are based on the historical volatility of the Company’s stock and vesting period of the option to be issued. The dividend yield is determined by annualizing the dividend rate as a percentage of the Company’s stock price. The following weighted-average assumptions were used for grants issued during the years ended December 31, 2016, 2015 and 2014: 2016 2015 2014 Range Range Range Weighted Weighted Weighted average Low High average Low High average Low High Risk-free interest rate % % % % % % % % % Expected dividend yield % % % % % % % % % Expected volatility % % % % % % % % % Expected life (years) The following table summarizes changes in stock option awards for the year ended December 31, 2016: 2016 Weighted average Stock Option Awards Shares exercise price Outstanding - beginning of year $ Granted Exercised Forfeited Outstanding - end of year $ Exercisable - end of year $ There were 285,999 options vested or expected to vest with a weighted average price of $10.45 at December 31, 2016.

The fair value of restricted stock amounts vested during the years ended December 31, 2016, 2015 and 2014 was $3.3 million, $4.5 million and $3.9 million, respectively. At December 31, 2016, there was $3.4 million of total unrecognized compensation cost related to unvested share-based compensation awards granted under the 2005 Plan. The cost is expected to be recognized over a weighted-average period of 1.8 years. Employee Stock Purchase Plan (ESPP) — The ESPP was established in January 2000 and is administered by the Compensation Committee of the Company. At the 2014 Annual Shareholders Meeting, shareholders of the Company approved an amendment to the ESPP, increasing the number of shares of common stock available for awards under the plan by 200,000. Employees may elect to have a percentage of their payroll deducted and applied to the purchase of Common Stock at a discount. In addition, the Company may make a matching contribution up to 50% of an employee’s deduction toward the purchase of additional Common Stock. No matching contribution was made for the years presented in the table below.

Commitments And Contingencies	16. Commitments and Contingencies Lease Commitments — The Company has various operating lease agreements for office space. Generally, leases are subject to rent escalation provisions in subsequent years and have renewal options at the end of the initial lease terms. Leasehold improvements are amortized over the useful life of the improvements or the lease term if shorter. Rent expense (excluding ancillary charges for common area expense, maintenance, etc.) for the years ended December 31, 2016, 2015 and 2014, was $5.8 million, $4.9 million and $5.1 million, respectively. The Company entered into sublease agreements for two leased locations and at December 31, 2016, future minimum sublease payments to be received are $1.1 million. A director holds interests in a bank location currently leased by the Company and interests in the building where the Company leased its former corporate offices. Rent payments under the related party leases were $2.1 million for the years ended December 31, 2016, 2015 and 2014, and the Company was current on these lease obligations at all times. Future contractual obligations of $0.2 million will be paid to entities controlled by the director and are included in the table below of future minimum lease payments under all non-cancelable operating leases. Year ending December 31, (in thousands) Amount 2017 $ 2018 2019 2020 2021 Thereafter Total $ In January 2016, the Company entered into a new lease for facilities at 1401 Lawrence Street, Denver, Colorado. The leased space became the primary executive offices for the Company and includes approximately 44,000 square feet space of office space and 4,000 square feet of ground level retail space for a banking facility. The Company took possession of the space on June 1, 2016 and commenced operations from that location in November 2016. The lease term is for 12 years with first year base rent of $1.5 million escalating 2% annually. The lease is cancelable after nine years subject to a termination fee of up to $1.6 million. Financial Instruments With Off-Balance Sheet Risk — In the normal course of business the Company has entered into financial instruments which are not reflected in the accompanying consolidated financial statements: At December 31, (in thousands) 2016 2015 Commitments to originate commercial or real estate construction loans and unused lines of credit granted to customers $ $ Commitments to originate consumer loans — personal lines of credit and equity lines $ $ Overdraft protection plans $ $ Letters of credit $ $ Unfunded commitments for unconsolidated investments $ $ Company guarantees $ $ Commitments to Originate — The Company makes contractual commitments to extend credit and provide standby letters of credit which are binding agreements to lend money to its customers at predetermined interest rates for a specific period of time. These commitments are not held for sale. The credit risk involved in issuing these financial instruments is essentially the same as that involved in granting on-balance sheet financial instruments. As such, the Company’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument is represented by the contractual amounts of those instruments. However, the Company applies the same credit policies, standards, and ongoing reassessments in making commitments and conditional obligations as it does for loans. In addition, the amount and type of collateral obtained, if deemed necessary upon extension of a loan commitment or standby letter of credit, is essentially the same as the collateral requirements provided for loans. Additional risk associated with providing these commitments arises when they are drawn upon, such as the demands on liquidity the Company would experience if a significant portion were drawn down at the same time. However, this is considered unlikely, as many commitments expire without being drawn upon and therefore do not necessarily represent future cash requirements. Overdraft Protection Plans — The Company provides personal credit lines on customer accounts to advance funds to cover overdrafts. Letters of Credit — The Company provides standby and commercial letters of credit during the normal course of business. Standby letters of credit guarantee performance of a customer to a third party while commercial letters of credit guarantee payments on behalf of our customers. Unfunded Commitments for Unconsolidated Investments — The Company has committed to purchase up to $11.5 million in limited partnership interests of four entities, of which $6.7 million was unfunded at December 31, 2016. Certain shareholders and directors also have interests in some of these entities. Company Guarantees — The Company guarantees, to the issuing merchant banks, the credit card debt transactions for certain customers. The Company also provides guarantees to the FHLB for certain forgivable loans used to support affordable housing in our market areas. Federal Reserve Bank Stock — The fair value of the Federal Reserve Bank stock approximates its carrying value, which is based on the redemption provisions of the Federal Reserve Bank. At December 31, 2016, the Company held 81,924 shares of Federal Reserve Bank stock with a fair value of $4.1 million(subscription value of $50). This investment represents 50% of the par value due to the Federal Reserve Bank to become a member bank and the stock cannot be sold, traded, or pledged as collateral for loans. Although the probability is remote, the remaining 50% or $4.1 million due to the Federal Reserve Bank may be callable at its discretion. Employment Contracts — Certain officers of the Company have entered into employment agreements providing for salaries and fringe benefits. In addition, severance is provided in the event of termination for other than cause, and under certain changes in control, a payment is required. Indemnification Agreements — The Company is subject to certain indemnification obligations in conjunction with agreements signed with officers and directors of the Company. The indemnification agreements require the Company to indemnify against judgments, fines, penalties and amounts paid in settlements incurred in connection with civil or criminal action or proceedings, as it relates to their services to the Company. To the extent the Company maintains an insurance policy or policies providing directors’ and officers’ liability insurance, the Indemnitee will be covered to the maximum extent of the coverage available for any director or officer of the Company. However, certain indemnification payments may not be covered under the Company’s directors’ and officers’ insurance coverage. The rights of the Indemnitee under the indemnification agreement are in addition to any rights the Indemnitee may have under the Company’s articles of incorporation or bylaws. While the likelihood is remote, payments under these indemnification agreements could materially affect net income in a particular quarter or annual period. Other Matters — The Company is involved in various lawsuits which have arisen in the normal course of business. It is management’s opinion, based upon advice of legal counsel, that the ultimate outcome of these lawsuits will not have a material impact upon the financial condition, cash flow or results of operations of the Company.

Regulatory Matters
Regulatory Matters	17. Regulatory Matters The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can trigger certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial condition and results of operations. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company and the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators regarding components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of regulatory capital (as defined in the regulations) to risk-weighted assets and of regulatory capital to average assets. At December 31, 2016 and 2015, management believes the Company and Bank meet all capital adequacy requirements to which they are subject. In January 2015, the Company implemented the Basel III capital rules adopted by the federal banking agencies in 2014. Basel III imposed higher minimum capital requirements, created a new Common Equity Tier 1 capital requirement, established a Capital Conservation Buffer (CCB) and changed the risk-weighting guidelines for various assets types. The CCB, which became effective in 2016, is designed to establish a capital range above minimum requirements to insulate banks from periods of stress and impose constraints on dividends, share repurchases and discretionary bonus payments when capital levels fall below prescribed levels. The minimum CCB in 2016 is 0.625% and increases 0.625% annually through 2019 to 2.5%. At December 31, 2016, the most recent notification from the Federal Reserve categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized the Bank must maintain minimum total risk-based, Common Equity Tier 1 risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events that management believes have changed the Bank’s categories. The following tables present amounts at December 31, 2016 and 2015 under the Basel III guidelines.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Measurements
Fair Value Measurements	18. Fair Value Measurements ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing an asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). · Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. · Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates and yield curves that are observable at commonly quoted intervals. · Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The Company evaluates fair value measurement inputs on an ongoing basis in order to determine if there is a change of sufficient significance to warrant a transfer between levels. For example, changes in market activity or the addition of new unobservable inputs could, in the Company’s judgment, cause a transfer to either a higher or lower level. A description of the valuation methodologies used for financial instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Available for Sale Securities – At December 31, 2016, the Company holds, as part of its investment portfolio, available for sale securities reported at fair value consisting of municipal securities, corporate debt securities, and TPS. The fair value of the majority of municipal securities are determined using widely accepted valuation techniques including matrix pricing and broker-quote based applications. Inputs include benchmark yields, reported trades, issuer spreads, prepayment speeds and other relevant items. As a result, the Company has determined that these valuations fall within Level 2 of the fair value hierarchy. The Company also holds TPS that are recorded at fair value based on unadjusted quoted market prices for identical securities in an active market. The majority of the TPS are actively traded in the market and as a result, the Company has determined that the valuation of these securities falls within Level 1 of the fair value hierarchy. The Company holds certain TPS and corporate debt securities for which unadjusted market prices are not available or the market is not active and are therefore classified as Level 2 or 3. In the second quarter of 2016, the Company transferred a TPS from Level 2 to Level 3 due to the lack of recent market activity. The Company uses broker-dealer quotes, valuations based on similar but not identical securities, or the most recent market trade (which may not be current) to price these securities. Unrealized gains on TPS Level 3 transfers and total net unrealized gains recognized in AOCI at December 31, 2016 and 2015 were immaterial. Derivative Financial Instruments – The Company uses interest-rate swaps as part of its cash flow strategy to manage its interest-rate risk. The valuation of these instruments is determined using widely accepted valuation techniques as discussed further below. The fair values of interest-rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. Pursuant to guidance in ASC 820, credit valuation adjustments are incorporated into the valuation to appropriately reflect both the Company’s own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings and thresholds. The Company uses Level 2 and Level 3 inputs to determine the valuation of its derivatives portfolio. The valuation of derivative instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs (Level 2 inputs), including interest rate curves and implied volatilities. The estimates of fair value are made using a standardized methodology that nets the discounted expected future cash receipts and cash payments (based on observable market inputs). Level 3 inputs include the credit valuation adjustments which use estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. At December 31, 2016 and 2015, the Company assessed the impact of the Level 3 inputs on the overall derivative valuations in terms of the significance of the credit valuation adjustments in basis points and as a percentage of the overall derivative portfolio valuation and the overall notional value. The Company’s assessment determined that credit valuation adjustments were not significant to the overall valuation of the portfolio. In addition, the significance of the credit value adjustments and overall derivative portfolio to the Company’s financial statements was considered. As a result of the insignificance of the credit value adjustments to the derivative portfolio valuations and the Company’s financial statements, the Company classified the derivative valuations in their entirety in Level 2. The Company uses foreign exchange forward contracts to mitigate exchange-rate risk arising from the Company’s foreign currency holdings to support its international banking product offering. Fair value measurements of these assets or liabilities are priced based on spot and forward foreign currency rates and the credit worthiness of the contract counterparty. These contracts are classified in Level 2. The following tables present the Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2016 and 2015, aggregated by the level in the fair value hierarchy within which those measurements fall. Fair value measurements using: Quoted prices in Significant other Significant active markets for observable unobservable Balance at identical assets inputs inputs (in thousands) December 31, 2016 (Level 1) (Level 2) (Level 3) Assets Available for sale securities: Trust preferred securities $ $ $ $ Corporate debt securities - - Municipal securities - - Total available for sale securities $ $ $ $ Derivatives: Fair value hedge $ $ - $ $ - Non-designated hedges - - Foreign exchange forward contracts - - Total derivative assets $ $ - $ $ - Liabilities Derivatives: Cash flow hedge $ $ - $ $ - Fair value hedge - - Non-designated hedges - - Foreign exchange forward contracts - - Total derivative liabilities $ $ - $ $ - Fair value measurements using: Quoted prices in Significant other Significant active markets for observable unobservable Balance at identical assets inputs inputs (in thousands) December 31, 2015 (Level 1) (Level 2) (Level 3) Assets Available for sale securities: Trust preferred securities $ $ $ $ Corporate debt securities - - Municipal securities - - Total available for sale securities $ $ $ $ Derivatives: Cash flow hedge $ $ - $ $ - Fair value hedge - - Non-designated hedges - - Foreign exchange forward contracts - - Total derivative assets $ $ - $ $ - Liabilities Derivatives: Cash flow hedge $ $ - $ $ - Fair value hedge - - Non-designated hedges - - Foreign exchange forward contracts - - Total derivative liabilities $ $ - $ $ - A reconciliation of the beginning and ending balances of assets measured at fair value, on a recurring basis, using Level 3 inputs follows: For the year ended December 31, (in thousands) 2016 2015 Beginning balance $ $ Transfers and purchases - Net accretion Sales / calls / maturities - Unrealized gain (loss) included in comprehensive income Ending balance $ $ Assets and liabilities measured on a nonrecurring basis Fair value is used on a nonrecurring basis to evaluate certain financial assets and financial liabilities in specific circumstances. Similarly, fair value is used on a nonrecurring basis for nonfinancial assets and nonfinancial liabilities such as foreclosed assets, other real estate owned, intangible assets, nonfinancial assets and liabilities evaluated in a goodwill impairment analysis and other nonfinancial assets measured at fair value for purposes of assessing impairment. A description of the valuation methodologies used for financial and nonfinancial assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy, is set forth below. Impaired Loans – Certain collateral-dependent impaired loans are reported at the fair value of the underlying collateral. Impairment is measured based on the fair value of the collateral, which is typically derived from appraisals that take into consideration prices in observed transactions involving similar assets and similar locations. Each appraisal is updated on an annual basis, either through a new appraisal, a new evaluation, or through the Company’s comprehensive internal review process. Appraised values are reviewed and monitored internally and fair value is assessed at least quarterly or more frequently when circumstances occur that indicate a change in fair value has occurred. The Company classified these impaired loans as Level 3. Other Real Estate Owned (OREO) – OREO represents real property taken by the Company either through foreclosure or through a deed in lieu thereof from the borrower. The fair value of OREO is based on property appraisals adjusted at management’s discretion to reflect a further decline in the fair value of properties since the time the appraisal analysis was performed. The inputs used to determine the fair value of OREO fall within Level 3. The Company may include within OREO other repossessed assets received as partial satisfaction of a loan. Other repossessed assets are not material and do not typically have readily determinable market values and are considered Level 3 inputs. The following tables present the Company’s nonfinancial assets measured at fair value on a nonrecurring basis at December 31, 2016 and 2015, aggregated by the level in the fair value hierarchy within which those measurements fall. Fair value measurements using: Quoted prices in Significant other Significant active markets for observable unobservable identical assets inputs inputs (in thousands) Total (Level 1) (Level 2) (Level 3) At December 31, 2016 Impaired loans $ $ - $ - $ OREO $ $ - $ - $ At December 31, 2015 Impaired loans $ $ - $ - $ OREO $ $ - $ - $ Gains and losses, which include the provision for losses on impaired loans, recorded in relation to assets and liabilities measured on a nonrecurring basis are presented below: Gain (loss) for the year ended December 31, (in thousands) 2016 2015 2014 Impaired loans $ $ $ OREO - In accordance with ASC 310, the fair value of OREO recorded as an asset is reduced by estimated selling costs.

(2) The fair value of OREO and collateral-dependent impaired loans is based on third-party property appraisals. The majority of the appraisals utilize at least two valuation approaches or a combination of approaches including a market approach, where prices and other relevant information generated by market transactions involving similar or comparable properties are used to determine fair value. Appraisals may include an ‘as is’ and ‘upon completion’ valuation scenarios. Adjustments are routinely made in the appraisal process by third-party appraisers to adjust for differences between the comparable sales and income data. Adjustments also result from the consideration of relevant economic and demographic factors with the potential to affect property values. Also, prospective values are based on the market conditions which exist at the date of inspection combined with informed forecasts based on current trends in supply and demand for the property types under appraisal. Positive adjustments disclosed in this table represent increases to the sales comparison and negative adjustment represent decreases. The following table includes the estimated fair value of the Company’s financial instruments. The methodologies for estimating the fair value of financial assets and financial liabilities measured at fair value on a recurring and nonrecurring basis are discussed above. The methodologies for estimating the fair value for other financial assets and financial liabilities are discussed below. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret market data in order to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts at December 31, 2016 and 2015. December 31, 2016 December 31, 2015 Carrying Estimated Carrying Estimated (in thousands) value fair value value fair value Financial assets: Cash and cash equivalents $ $ $ $ Investment securities available for sale Investment securities held to maturity Other investments Loans — net Accrued interest receivable Derivatives Financial liabilities: Deposits $ $ $ $ Securities sold under agreements to repurchase Short-term borrowings Accrued interest payable Subordinated notes payable Junior subordinated debentures Derivatives The fair value estimation methodologies utilized by the Company for financial instruments and the classification level within the fair value hierarchy that those instruments fall are summarized as follows: Cash and Cash Equivalents — The carrying amount of cash and cash equivalents is a reasonable estimate of fair value which is classified as Level 2. Other Investments — Included in this category are the Company’s investment in the FHLB and other equity method investments. Due to restrictions on transferability, it is not practical to estimate fair value on the FHLB investment which is reported at carrying value. The fair value of other equity method investments approximates fair value and is classified as Level 2. Loans — The fair value of loans is estimated by discounting future contractual cash flows using estimated market rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. In computing the estimate of fair value for all loans, the estimated cash flows and/or carrying value have been reduced by specific and general reserves for loan losses. The fair value of loans disclosed in the table above, which is not the exit price, is classified as Level 3 within the fair value hierarchy. Accrued Interest Receivable/Payable — The fair value of accrued interest receivable/payable approximates the carrying amount due to the short-term nature of these amounts and is classified in the same level hierarchy as the underlying assets/liabilities. Deposits — The fair value of certificates of deposit is estimated by discounting the expected life using an index of the U.S. Treasury curve. Non-maturity deposits are reflected at their carrying value for purposes of estimating fair value. The fair value of all deposits is classified as Level 2. Securities Sold Under Agreements to Repurchase — Estimated fair value is based on discounting cash flows and is classified as Level 2. Short-Term Borrowings — The estimated fair value of short-term borrowings approximates their carrying value, due to their short-term nature and is classified as Level 2. Subordinated Notes Payable — The estimated fair value of subordinated notes payable is based on discounting cash flows for comparable instruments and is classified as Level 3. Junior Subordinated Debentures — The estimated fair value of junior subordinated debentures approximates their carrying value, due to the variable interest rate paid on the debentures and is classified as Level 2. Commitments to Extend Credit and Standby Letters of Credit — The Company’s off-balance sheet commitments are funded at current market rates at the date they are drawn upon. It is management’s opinion that the fair value of these commitments would approximate their carrying value, if drawn upon, and are classified as Level 3. The fair value estimates presented herein are based on pertinent information available to management at December 31, 2016 and 2015. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since that date and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

Nature of Operations and Significant Accounting Policies
Use Of Estimates	Use of Estimates – The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (GAAP) and, where applicable, prevailing practices within the financial services industry. In preparing the consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amount 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 significantly from those estimates.
Reclassifications	Reclassifications – Certain reclassifications have been made to prior years’ consolidated financial statements and related notes to conform to current year presentation including: the effects of discontinued operations and the aggregation of certain line items in the consolidated statements of cash flows. Refer to Note 2 – Discontinued Operations for additional information.
Basis of Presentation	Basis of Presentation — The consolidated financial statements include entities in which the Parent has a controlling financial interest. These entities include; the Bank; CoBiz Insurance, Inc.; and CoBiz IM. Intercompany balances and transactions are eliminated in consolidation. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (VIE). The voting interest model is used when the equity investment is sufficient to absorb the expected losses and the equity investment has all of the characteristics of a controlling financial interest. Under the voting interest model, the party with the controlling voting interest consolidates the legal entity. The VIE model is used when any of the following conditions exist: the equity investment at risk is not sufficient to finance the entity’s activities without additional subordinated financial support; the holders of the equity investment do not have a controlling voting interest; or the holders of the equity investment are not obligated to absorb the expected losses or residual returns of the legal entity. An enterprise is considered to have a controlling financial interest of a VIE if it has both the power to direct the activities that most significantly impact economic performance and the obligation to absorb losses, or receive benefits, that are significant to the VIE. An enterprise that has a controlling financial interest is considered the primary beneficiary and must consolidate the VIE. The Company was not the primary beneficiary of a VIE at December 31, 2016 or December 31, 2015.
Cash and Cash Equivalents	Cash and Cash Equivalents — The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents include amounts that the Company is required to maintain at the Federal Reserve Bank of Kansas City (Federal Reserve Bank) to meet certain regulatory reserve balance requirements. At December 31, 2016 and 2015, the Company had reserve requirements of $24.3 million and $18.2 million, respectively. The following table shows supplemental disclosures of certain cash and noncash items: For the year ended December 31, (in thousands) 2016 2015 2014 Cash paid during the period for: Interest $ $ $ Income taxes, net Other noncash activities: Loans transferred to held for sale Loans transferred to OREO - - Trade date accounting for investment securities - Available for sale securities transferred to held to maturity - -
Investments	Investments — The Company classifies its investment securities as held to maturity, available for sale or trading, according to management’s intent. Investment security transactions are recorded on a trade date basis. At December 31, 2016 and 2015, the Company had no trading securities. Available for sale securities consist of bonds, notes and debentures (including corporate debt and TPS) not classified as held to maturity securities and are reported at fair value as determined by quoted market prices. Unrealized holding gains and losses, net of tax, are reported as a net amount in AOCI until realized. Investment securities held to maturity consist of residential mortgage-backed securities (MBS), bonds, notes, debentures for which the Company has the positive intent and ability to hold to maturity and are reported at cost, adjusted for amortization or accretion of premiums and discounts. Premiums and discounts, adjusted for prepayments as applicable, are recognized in interest income. Other than temporary declines in the fair value of individual investment securities held to maturity and available for sale are charged against earnings. Gains and losses on disposal of investment securities are determined using the specific identification method. Other-than-temporary-impairment (OTTI) on debt securities is separated between the amount that is credit related (credit loss component) and the amount due to all other factors. The credit loss component is recognized in earnings and is the difference between a security’s amortized cost basis and the discounted present value of expected future cash flows. The amount due to all other factors is recognized in other comprehensive income (loss) (OCI). See Note 3 – Investments.
Bank Stocks	Bank Stocks — Federal Home Loan Bank of Topeka (FHLB), Federal Reserve Bank and other correspondent bank stocks are accounted for under the cost method. See Note 3 – Investments.
Loans Held for Investment	Loans Held for Investment — Loans that the Company has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal balance adjusted for any charge-offs, the allowance for loan losses, deferred fees and costs on originated loans, and unamortized premiums or discounts on purchased loans. Interest is accrued and credited to income daily based on the principal balance outstanding. The accrual of interest income is generally discontinued when a loan becomes 90 days past due as to principal and interest. When a loan is designated as nonaccrual, the current period’s accrued interest receivable is charged against current earnings while any portions relating to prior periods are charged against the allowance for loan losses. Interest payments received on nonaccrual loans are generally applied to the principal balance of the loan. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured and there has been demonstrated performance in accordance with contractual terms. The Company may elect to continue the accrual of interest when the loan is in the process of collection and the realizable value of collateral is sufficient to cover the principal balance and accrued interest.
Loans Held for Sale	Loans Held for Sale — Loans held for sale include loans the Company has demonstrated the ability and intent to sell. Loans held for sale are primarily nonperforming loans. Loans held for sale are carried at the lower of cost or fair value and are evaluated on a loan-by-loan basis.
Impaired Loans	Impaired Loans — Impaired loans, with the exception of groups of smaller-balance homogenous loans that are collectively evaluated for impairment, are defined as loans for which, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays of less than 90 days and monthly payment shortfalls of less than 10% of the contractual payment on a consumer loan generally are not classified as impaired if the Company ultimately expects to recover its full investment. The Company determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. Loans that are deemed to be impaired are evaluated in accordance with Accounting Standards Codification (ASC) Topic 310-10-35, Receivables – Subsequent Measurement (ASC 310) and ASC Topic 450-20, Loss Contingencies (ASC 450). Included in impaired loans are troubled debt restructurings. A troubled debt restructuring is a formal restructure of a loan where the Company, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, including but not limited to reduction in the stated interest rate, reduction in the loan balance or accrued interest, or extension of the maturity date. Troubled debt restructurings are evaluated in accordance with ASC Topic 310-40, Troubled Debt Restructurings by Creditors. Interest payments on impaired loans are typically applied to principal unless collectability of principal is reasonably assured. Loans that have been modified in a formal restructuring are typically returned to accrual status when there has been a sustained period of performance (generally six months) under the modified terms, the borrower has shown the ability and willingness to repay and the Company expects to collect all amounts due under the modified terms.
Loan Origination Fees and Costs	Loan Origination Fees and Costs — Loan fees and certain costs of originating loans are deferred and the net amount is amortized over the contractual life of the related loans in accordance with ASC Topic 310-20, Nonrefundable Fees and Other Costs.
Allowance for Loan Losses	Allowance for Loan Losses — The allowance for loan losses (ALL) is established as losses are estimated to have occurred through a provision for loan losses charged against earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The ALL is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as new information becomes available.
Allowance for Credit Losses	Allowance for Credit Losses — The allowance for credit losses is established as losses are estimated to have occurred through a provision for credit losses charged to earnings. The allowance for credit losses represents management’s recognition of a separate reserve for off-balance sheet loan commitments and letters of credit. While the allowance for loan losses is recorded as a contra-asset to the loan portfolio on the consolidated balance sheets, the allowance for credit losses is recorded under the caption “Accrued interest and other liabilities”. Although the allowances are presented separately on the balance sheets, any losses incurred from credit losses would be reported as a charge-off in the allowance for loan losses, as any loss would be recorded after the off-balance sheet commitment had been funded. See Note 4 – Loans.
Intangible Assets	Intangible Assets — Intangible assets, primarily consisting of customer contracts and relationships, are being amortized by the straight-line method over 10 to 15 years. See Note 6 – Intangible Assets.
Bank-Owned Life Insurance (BOLI)	Bank-Owned Life Insurance (BOLI) – The Bank invested in BOLI policies to fund certain future employee benefit costs and are recorded at net realizable value. Changes in the amount that could be realized, including death benefits in excess of the carrying amount, are recorded in the consolidated statements of income under the caption “Other Income.”
Premises and Equipment	Premises and Equipment – Premises and equipment are stated at cost less accumulated depreciation and amortization, which is calculated using the straight-line method over the estimated useful lives of generally three to ten years. Leasehold improvements are capitalized and amortized using the straight-line method over the terms of the respective leases or the estimated useful lives of the improvements, whichever is shorter. The Company reviews the carrying value of property and equipment for indications of impairment in accordance with ASC Topic 360-10-35, Impairment or Disposal of Long-Lived Assets. See Note 5 – Premises and Equipment.
Other Assets	Other Assets – Included in other assets are certain investments (Funds), where the Company has the ability to exercise significant influence or has ownership between 20% and 50% that are accounted for under the equity method. The Funds are equity method investments licensed as Small Business Investment Companies that invest primarily in subordinated debt securities. In certain circumstances, the Funds may also receive warrants or other equity positions as part of their investments. There were no significant transactions between the Company and the Funds for the years ended December 31, 2016, 2015, and 2014. The Company recognized income (loss) from the Funds of $2.5 million, $1.3 million, and $(0.1) million for the years ended December 31, 2016, 2015, and 2014, respectively, which is included in “Other Income” in the consolidated statements of income.
Repossessed Assets	Repossessed Assets – Assets acquired through repossession are held for sale and initially recorded at estimated fair value at the date of repossession. Subsequent to repossession, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Repossessed assets are reported in the consolidated balance sheets under the caption “Other Assets.” There were no repossessed assets at December 31, 2016 and 2015.
Other Real Estate Owned (OREO)	Other Real Estate Owned (OREO) – OREO held for sale acquired through foreclosure, physical possession or in settlement of debt is valued at estimated fair value, less estimated costs to sell, at the date of receipt. Subsequent to foreclosure, OREO is carried at the lower of carrying amount or fair value less costs to sell. Subsequent declines in value are charged to operations. Activity in the valuation allowance on OREO for the years ended December 31, 2016, 2015, and 2014 is as follows: For the year ended December 31, (in thousands) 2016 2015 2014 Beginning balance $ $ $ Additions - Deductions due to sales - Ending balance $ $ $
Securities Sold Under Agreements to Repurchase	Securities Sold Under Agreements to Repurchase – The Company sells certain securities under agreements to repurchase with its customers. The agreements transacted with its customers are utilized as an overnight investment product. These agreements are treated as secured borrowings, where the agreements are reflected as a liability of the Company and the securities underlying the agreements are reflected as a Company asset in accordance with ASC Topic 860, Transfers and Servicing. See Note 8 – Borrowed Funds.
Derivative Instruments	Derivative Instruments — Derivative financial instruments are accounted for at fair value. The Company utilizes interest rate swaps to hedge a portion of its exposure to interest rate changes. These instruments are accounted for as cash flow hedges, as defined by ASC Topic 815, Derivatives and Hedging (ASC 815). The Company also uses interest rate swaps to hedge against adverse changes in fair value on fixed-rate loans. These instruments are accounted for as fair value hedges in accordance with ASC 815. The net cash flows from the cash flow and fair value hedges are classified in operating activities within the consolidated statements of cash flows with the hedged items. The Company also offers an interest rate hedge program that includes various derivative products, including swaps, to customers of the Bank. The fair value amounts recognized for derivative instruments and the fair value amounts recognized for the right to reclaim or obligation to return cash collateral are not offset when represented under a master netting arrangement. The Company also uses foreign currency forward contracts (FX forwards) giving it the right to sell underlying currencies at specified future dates and predetermined prices in order to mitigate foreign exchange risk associated with long positions. FX forwards are carried at fair value with changes in value recognized in current earnings as the contracts are not designated as hedging instruments. See Note 10 – Derivatives.
Self-Insurance Reserves	Self-Insurance Reserves – The Company self-insures a portion of its employee medical costs. The Company maintains a liability for incurred-but-not-reported claims based on assumptions as to eligible employees, historical claims experience and lags in claims reporting.
Investment Advisory Income	Investment Advisory Income – Fees earned from providing investment advisory services are based on the market value of assets under management and are collected at the end of each quarter.
Insurance Income	Insurance Income – Insurance income includes commissions on the sale of life and property and casualty insurance policies, and other employee benefit products earned as an agent for unaffiliated insurance underwriters. Property and casualty income is primarily recognized upon policy origination and renewal dates. Benefits brokerage income is recognized on a monthly basis as the customer pays their insurance premiums .
Income (loss) From Discontinued Operations, Net of Income Taxes	Income (loss) From Discontinued Operations, Net of Income Taxes – Income (loss) from discontinued operations, net of income taxes for the years ended December 31, 2016, 2015 and 2014 includes the closure of GMB, which is discussed in Note 2 – Discontinued Operations.
Income Taxes	Income Taxes – A deferred income tax liability or asset is recognized for temporary differences which exist in the recognition of certain income and expense items for financial statement reporting purposes in periods different than for tax reporting purposes. The provision for income taxes is based on the amount of current and deferred income taxes payable or refundable at the date of the financial statements as measured by the provisions of current tax laws. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, taxes paid in prior carryback years, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. See Note 11 – Income Taxes.
Stock-Based Compensation	Stock-Based Compensation — Pursuant to ASC Topic 718, Compensation – Stock Compensation (ASC 718), the Company recognizes the fair value of stock-based awards to employees as compensation cost over the requisite service period. See Note 15 – Employee Benefit and Stock Compensation Plans.
Earnings Per Common Share	Earnings Per Common Share — Basic and diluted earnings per share is based on the two-class method prescribed in ASC Topic 260, Earnings Per Share (ASC 260). The weighted-average number of shares outstanding used to compute diluted earnings per share include the number of additional common shares that would be outstanding if the potential dilutive common shares and common share equivalents had been issued at the beginning of the period. See Note 14 – Earnings per Common Share.
Segment Information	Segment Information - The Company has disclosed separately the results of operations relating to its segments in Note 19 – Segments.
Fair Value Measurements	Fair Value Measurements — The Company measures financial assets, financial liabilities, nonfinancial assets and nonfinancial liabilities pursuant to ASC Topic 820, Fair Value Measurements and Disclosures (ASC 820). ASC 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. See Note 18 - Fair Value Measurements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements — In May 2014, the FASB issued ASU No. 2014-9 (ASU 2014-09), Revenue from Contracts with Customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer, as well as enhanced disclosure requirements. In August 2015, the FASB issued ASU 2015-14 which deferred the effective date of ASU 2014-09 to fiscal years, and interim reporting periods within those fiscal years, beginning after December 15, 2017. In March 2016, the FASB issued ASU 2016-08 which clarified the revenue recognition implementation guidance on principal versus agent considerations and is effective during the same period as ASU 2014-09. In April 2016, the FASB issued ASU 2016-10 which clarified the revenue recognition guidance regarding the identification of performance obligations and the licensing implementation and is effective during the same period as ASU 2014-09. In May 2016, the FASB issued ASU 2016-12 which narrowly amended the revenue recognition guidance regarding collectability, noncash consideration, presentation of sales tax and transition. ASU 2016-12 is effective during the same period as ASU 2014-09. The Company is currently evaluating the effects of these ASUs on its financial statements and disclosures, if any. Preliminarily, the Company expects these ASUs to have more of an impact on the Fee-Based Lines segment than Commercial Banking segment, which generates the majority of the Company’s revenue. The Company has conducted its initial assessment and is currently evaluating contracts to assess and quantify accounting methodology changes resulting from the adoption of ASU 2014-09. Revenue from the Fee-Based Lines segment includes property and casualty brokerage income, employee benefit brokerage income and investment advisory income which totaled $18.3 million in 2016. While the timing of revenue recognition from these sources may change, the Company does not expect a material impact to its financial statements. In August 2014, the FASB issued ASU 2014-15 (ASU 2014-15), Presentation of Financial statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s ability to Continue as a Going Concern. ASU 2014-15 contains amendments intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Currently, GAAP lacks guidance about management’s responsibility to evaluate whether there is substantial doubt about the organization’s ability to continue as a going concern or to provide related footnote disclosures. ASU 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods beginning thereafter. The adoption of ASU 2014-15 did not have an impact on the financial statements. In February 2016, the Financial Accounting Standard Board (FASB) issued Accounting Standard Update (ASU) 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 is intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about lease arrangements. For public business entities, this ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018. The Company is currently evaluating the effects of ASU 2016-02 on its financial statements and disclosures by taking inventory of all existing lease arrangements. Preliminarily, the Company expects the primary impact of ASU 2016-02 will relate to its office locations, the majority of which are designated as operating leases. The Company has future operating lease obligations for its locations of $33.4 million that are being evaluated as potential lease assets and liabilities, as defined in ASU 2016-02. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (ASU 2016-09). ASU 2016-09 includes provisions intended to simplify various aspects related to accounting for and presentation of share-based payments in the financial statements. The areas for simplification include income tax consequences, forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2016, and early adoption is permitted for financial statements that have not been previously issued. The Company early adopted the provisions of ASU 2016-09 during the quarter ended March 31, 2016. The cumulative effect adjustment from the modified retrospective transition of the income tax consequences, forfeitures and the classification of awards did not have a material effect on the Company’s financial statements or disclosures. Changes to the statement of cash flows have been applied prospectively beginning in the first quarter of 2016. See Note 15 - Employee Benefit and Stock Compensation Plans. In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). The objective of ASU 2016-13 is to provide financial statement users with decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit. ASU 2016-13 includes provisions that require financial assets measured at amortized cost (such as loans and held to maturity (HTM) debt securities) to be presented at the net amount expected to be collected. This will be accomplished through recognition of an estimate of all current expected credit losses. The estimate will include forecasted information for the timeframe that an entity is able to develop reasonable and supportable forecasts. This is a change from the current practice of recognizing incurred losses based on the probable initial recognition threshold under current GAAP. In addition, credit losses on available for sale (AFS) debt securities will be recorded through an allowance for credit losses rather than as a write-down. Under ASU 2016-13, an entity will be able to record reversals of credit losses in current period income when the estimate of credit losses declines, whereas current GAAP prohibits reflecting those improvements in current period earnings. ASU 2016-13 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2019, and early adoption is permitted for fiscal years, including interim periods, beginning after December 15, 2018. ASU 2016-13 will be applied through a cumulative effect adjustment to retained earnings (modified-retrospective approach), except for debt securities for which an other-than-temporary impairment had been recognized before the effective date. A prospective transition approach is required for these debt securities. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures, and expects ASU 2016-13 to add complexity and costs to its current credit loss evaluation process. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15), regarding how certain cash receipts and cash payments are presented and classified in the statements of cash flows. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments of ASU 2016-13 are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Amendments in this ASU should be applied using a retrospective transition method to each period presented. The Company is evaluating the effects ASU 2016-15 will have on its financial statements and disclosures, and does not expect these effects to be material. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (ASU 2016-20). The amendments in ASU 2016-20 affect certain aspects of the guidance issued in ASU 2014-06 including loan guarantee fees, contract costs, provisions for losses on construction-type and production-type contracts, disclosure of remaining performance obligations, contract modifications, contract asset vs. receivable, refund liability, advertising costs, fixed odds wagering contracts in the casino industry, and costs capitalized for advisors to private funds and public funds. The effective date of these amendments are at the same date that ASU 2014-09, which is discussed above, is effective.

(2) The fair value of OREO and collateral-dependent impaired loans is based on third-party property appraisals. The majority of the appraisals utilize at least two valuation approaches or a combination of approaches including a market approach, where prices and other relevant information generated by market transactions involving similar or comparable properties are used to determine fair value. Appraisals may include an ‘as is’ and ‘upon completion’ valuation scenarios. Adjustments are routinely made in the appraisal process by third-party appraisers to adjust for differences between the comparable sales and income data. Adjustments also result from the consideration of relevant economic and demographic factors with the potential to affect property values. Also, prospective values are based on the market conditions which exist at the date of inspection combined with informed forecasts based on current trends in supply and demand for the property types under appraisal. Positive adjustments disclosed in this table represent increases to the sales comparison and negative adjustment represent decreases.
