	Basis of Presentation
	Nature of Operations
	CommunityOne Bancorp, or "COB" or the "Company"(which also refers to us and our subsidiaries on a consolidated basis), is a bank holding company incorporated in 1984 under the laws of the State of North Carolina. Through our ownership of CommunityOne Bank, N.A., or the "Bank", a national banking association headquartered in Asheboro, North Carolina, we offer a complete line of consumer, wealth management, mortgage and business banking services, including loan, deposit, cash management, investment management and trust services, to individual and business customers through operations located throughout central, southern and western North Carolina. The Bank also holds the stock of Dover Mortgage Company (“Dover”) and First National Investor Services, Inc. Dover previously engaged in the business of originating, underwriting and closing mortgage loans for sale in the secondary market. Dover ceased operations in the first quarter of 2011 and filed for Chapter 11 bankruptcy on February 15, 2012. First National Investor Services, Inc. holds deeds of trust for the Bank.
	COB also owns Granite Mortgage, Inc., which ceased mortgage operations in 2009 and filed for Chapter 11 bankruptcy on February 15, 2012, and FNB United Statutory Trust I, FNB United Statutory Trust II, and Catawba Valley Capital Trust II, which were formed to facilitate the issuance of trust preferred securities.
	On October 21, 2011, as part of the recapitalization of COB, COB acquired Bank of Granite Corporation and its subsidiary bank, Bank of Granite, through the merger of a wholly owned subsidiary of ours into Granite Corp. (the “Merger”). Bank of Granite was merged into the Bank on June 8, 2013. Our shareholders approved an amendment in our articles of incorporation to change our name from FNB United Corp. to CommunityOne Bancorp on June 20, 2013. This change, along with a change in our stock symbol from FNBN to COB, was implemented on July 1, 2013.
	We earn revenue primarily from interest on loans and securities investments, mortgage banking income and fees charged for financial services provided to our customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses and write-downs in the value of, gains and losses on disposition of and holding costs associated with our OREO, and other operating costs such as: salaries and employee benefits, occupancy, data processing expenses, merger related expenses and tax expense.
	General
	The accompanying consolidated financial statements, prepared without audit, include the accounts of COB and its subsidiaries. All significant intercompany balances and transactions have been eliminated. Descriptions of the organization and business of COB, accounting policies followed by COB and other relevant information are contained in our Annual Report on Form 10-K for the year ended December 31, 2012 (the "Form 10-K"), including the notes to the consolidated financial statements filed as part of that report. This quarterly report should be read in conjunction with the Form 10-K.
	In the opinion of management, the accompanying consolidated financial statements contain the adjustments, all of which are normal recurring adjustments, necessary to present fairly the financial position of COB as of September 30, 2013 and December 31, 2012, and the results of its operations and cash flows for the three and nine months ended September 30, 2013 and 2012, respectively.
	All financial information is reported on a continuing operations basis, unless otherwise noted. See Note 2 to the consolidated financial statements for a discussion regarding discontinued operations and certain assets and liabilities at September 30, 2013 and December 31, 2012.
	Use of Estimates
	We have made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with accounting principles generally accepted in the United States ("GAAP"). Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowances for loan losses (“ALL”), estimated cash flows of purchased impaired loans, the carrying value of other real estate owned (“OREO”), the carrying value of intangible assets and the realization of deferred tax assets.
	Reclassification
	Certain reclassifications have been made to the prior period consolidated financial statements to place them on a comparable basis with the current period consolidated financial statements. These reclassifications have no effect on net income or shareholders' equity as previously reported.
	Recent Accounting Pronouncements
	Comprehensive Income - In February 2013, the FASB issued ASU No. 2013-02 Comprehensive Income (Topic 220): "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (“ASU No. 2013-02”). This pronouncement requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income for each applicable component of net income, as well as a roll forward of the components of accumulated other comprehensive income on a prospective basis. This pronouncement is effective beginning January 1, 2013. The provisions of ASU No. 2013-02 relate only to financial statement presentation of other comprehensive income and, accordingly, its adoption did not have a material effect on COB's financial statements. These new disclosures appear in Note 10.
	FASB - From time to time, the Financial Accounting Standards Board (“FASB”) issues exposure drafts for proposed statements of financial accounting standards. Such exposure drafts are subject to comment from the public, to revisions by the FASB and to final issuance by the FASB as statements of financial accounting standards.
	Management considers the effect of the proposed statements on the consolidated financial statements of COB and monitors the status of changes to and proposed effective dates of exposure drafts. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on our financial position, results of operations or cash flows.

Discontinued Operation, Additional Disclosures [Abstract]	'
Discontinued Operations	'
	Discontinued Operations
	All operations of Dover, a subsidiary of the Bank, were discontinued as of March 17, 2011. Dover, acquired by us in 2003, originated, underwrote and closed mortgage loans for sale into the secondary market. It maintained a retail origination network based in Charlotte, North Carolina, which originated loans for properties located in North Carolina. Dover also engaged in the wholesale mortgage origination business and conducted retail mortgage origination business outside of North Carolina. Operations outside of the State of North Carolina and the wholesale mortgage origination business were discontinued in February 2011, and all remaining operations were discontinued on March 17, 2011. Dover filed for Chapter 11 bankruptcy on February 15, 2012 in the United States Bankruptcy Court for the Western District of North Carolina. All of the assets and liabilities of Dover were written off at that time.

	Goodwill and Other Intangible Assets
	We accounted for the Merger as a business combination under the acquisition method of accounting. As a result, we have recognized in our financial statements the identifiable net assets acquired and an amount of goodwill (representing the difference between the purchase price and the identifiable net assets). During the measurement period following a business combination, the amount of identifiable net assets recognized is subject to further adjustment to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. GAAP requires that the measurement period cannot exceed one year from the acquisition date. During the first quarter of 2012, we recognized $0.3 million in additional goodwill from the Merger. This additional amount resulted from new valuations received on OREO acquired in the Merger, which were written down to our best estimate of fair value.
	Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually. Impairment exists when the carrying value of goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess and would be included in noninterest expense in the Consolidated Statements of Operations. None of the goodwill recognized in the Merger is expected to be deductible for income tax purposes.
	Our intangible assets with definite lives are core deposit premiums ("CDP") and mortgage servicing rights ("MSR"). CDPs are amortized over their useful lives to their estimated residual value and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits. MSRs are amortized over the expected lives of the underlying mortgages including prepayment estimates.

	Investment Securities
	Securities designated as available-for-sale are carried at fair value. However, the unrealized difference between amortized cost and fair value of securities available-for-sale is excluded from net income unless there is an other than temporary impairment and is reported, net of deferred taxes, as a component of shareholders' equity as accumulated other comprehensive income (loss). Securities held-to-maturity are carried at amortized cost, as the bank has the ability, and management has the positive intent, to hold these securities to maturity. Premiums and discounts on securities are amortized and accreted according to the interest method.
	Our primary objective in managing the investment portfolio is to maintain a portfolio of high quality, highly liquid investments yielding competitive returns. We are required under federal regulations to maintain adequate liquidity to ensure safe and sound operations. We maintain investment balances based on a continuing assessment of cash flows, the level of loan production, current interest rate risk strategies and an assessment of the potential future direction of market interest rate changes. Investment securities differ in terms of default, interest rate, liquidity and expected rate of return risks.
	The following table summarizes the amortized cost and estimated fair value of investment securities and presents the related gross unrealized gains and losses:

	As a member of the Federal Home Loan Bank of Atlanta (“FHLB”), the Bank is required to own capital stock in the FHLB based generally upon the balances of total assets and FHLB advances. FHLB capital stock is pledged to secure FHLB advances. This investment is carried at cost since no ready market exists for FHLB stock and there is no quoted market value. However, redemption of this stock has historically been at par value. The Bank owned a total of $5.9 million of FHLB stock at September 30, 2013 and $6.3 million at December 31, 2012. Due to the redemption provisions of FHLB stock, we have estimated that fair value approximated cost and that this investment was not impaired at September 30, 2013. FHLB stock is included in other assets at its original cost basis.
	As a member bank of the Federal Reserve Bank of Richmond (“FRBR”), the Bank also is required to own capital stock of the FRBR based upon a percentage of the bank's common stock and surplus. This investment is carried at cost since no ready market exists for FRBR stock and there is no quoted market value. At September 30, 2013 and December 31, 2012, the Bank owned a total of $4.1 million and $3.1 million of FRBR stock, respectively. Due to the nature of this investment in an entity of the U.S. government, we have estimated that fair value approximated the cost and that this investment was not impaired at September 30, 2013. FRBR stock is included in other assets at its original cost basis.
	At September 30, 2013, $94.1 million of the investment securities portfolio was pledged to secure public deposits, $18.4 million was pledged to retail repurchase agreements and $78.9 million was pledged to others, leaving $394.1 million available as lendable collateral.
	During the three and nine months ended September 30, 2013, the Bank sold securities with a book value of $3.3 million and $175.1 million respectively, and recognized gains of $0.1 million and $2.8 million, respectively. During the three and nine months ended September 30, 2012, the Bank sold securities with a book value of $21.4 million and $134.1 million respectively, and recognized a loss of $(33) thousand, and a gain of $1.9 million, respectively. The Bank sold these securities in order to manage our interest rate sensitivity profile.
	The following tables show our investments' estimated fair value and gross unrealized losses, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position, at September 30, 2013 and December 31, 2012. The change in unrealized losses during the three and nine month periods ending September 30, 2013 was attributed to changes in interest rates and not to changes in the credit quality of these securities. All unrealized losses on investment securities are considered by management to be temporary given the credit quality of these investment securities or the short duration of the unrealized loss, or both.

At September 30, 2013 and December 31, 2012, there were zero and four available-for-sale securities that were in an unrealized loss position for longer than 12 months, respectively.
If an entity has a debt security that has been in a loss position for over 12 months and it cannot assert it is more likely than not that it will not have to sell the security before recovery, then other than temporary impairment ("OTTI") must be taken. The amount of impairment is bifurcated between impairment due to credit (which is recorded through earnings) and noncredit impairment (which becomes a component of other comprehensive income (“OCI”) for both available-for-sale and held-to-maturity securities). For held-to-maturity securities, the amount in OCI will be amortized prospectively over the security's remaining life. After analyzing our securities portfolio at September 30, 2013, and after considering ratings, fair value, cash flows and other factors, we did not have any OTTI during the three or nine months ended September 30, 2013 and September 30, 2012.
The aggregate amortized cost and fair value of securities at September 30, 2013, by remaining contractual maturity, are shown in the following table. Actual expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations.

	Loans and Allowance for Loan Losses
	General

	Loans held for investment are stated at the principal amounts outstanding adjusted for purchase premiums/discounts, deferred net loan fees and costs, and unearned income. We report our loan portfolio by segments and classes, which are disaggregations of portfolio segments. Our portfolio segments are: Commercial and agricultural, Real estate, and Consumer loans. The Commercial and agricultural loan and Consumer loan portfolios are not further segregated into classes. The classes within the Real estate portfolio segment include Real estate - construction and Real estate mortgage, which is further broken into 1-4 family residential mortgage and Commercial real estate mortgage loans.

	Loan fees and the incremental direct costs associated with originating a loan are deferred and subsequently recognized over the life of the loan as an adjustment to interest income.

	In addition to originating loans, we also purchase loans. At acquisition, purchased loans are designated as either purchased contractual loans ("PC loans") or purchased impaired loans ("PI loans"). PC loans are acquired loans where management believes it is probable that it will receive all principal as of the date of acquisition. These loans are accounted for under the contractual cash flow method, under ASC 310-20. Any discount or premium paid on PC loans is recorded in interest income using the effective yield method over the expected life of the loans.

	PI loans are acquired loans where management believes, at acquisition date, it is probable that all principal on the acquired loans will not be received. PI loans are placed in homogeneous risk based pools where accounting for projected cash flows is performed, as allowed under ASC 310-30. Once a pool is established the individual loans within each pool do not change. As management obtains new information related to changes in expected principal loss and expected cash flows, by pool, we record either an increase in yield when new expected cash flows increase, an allowance for loan losses when new expected cash flows decline, or a decrease in yield when there is only a timing difference in expected cash flows.

	Loans acquired in the Merger ("Granite Purchased Loans") included PI loans and PC loans. Loans designated as PC loans included performing revolving consumer and performing revolving commercial loans on acquisition date.

	During the nine months ended September 30, 2013, we purchased $134.8 million of performing residential mortgage loans, including premiums of $1.0 million. During the nine months ended September 30, 2012, we purchased $173.2 million of performing residential mortgage loans, including premiums of $4.0 million. These loan purchases are accounted for as PC loans.

	ALL Methodology
	COB's ALL, which is utilized to absorb actual losses in the loan portfolio, is maintained at a level consistent with management's best estimate of probable loan losses to be incurred as of the balance sheet date. Management assesses COB's ALL quarterly. This assessment includes a methodology that separates the total loan portfolio into homogeneous loan classifications for purposes of evaluating risk. The required allowance is calculated by applying a risk adjusted reserve requirement to the dollar volume of loans within a homogenous group. For purposes of the ALL, we have grouped our loans into pools according to the loan segmentation regime employed on schedule RC-C of the FFIEC's Consolidated Report of Condition and Income. Major loan portfolio subgroups include: risk graded commercial loans, mortgage loans, home equity loans, retail loans and retail credit lines. Management also analyzes the loan portfolio on an ongoing basis to evaluate current risk levels, and risk grades are adjusted accordingly. While management uses the best information available to make evaluations, future adjustments may be necessary, if economic or other conditions differ substantially from the assumptions used.
	Historical loss rates are calculated by associating losses to the risk-graded pool to which they relate for each of the previous eight quarters. Then, using a look back period consisting of the twenty most recent quarters, loss factors are calculated for each risk-graded pool using a simple average. This represents a change in methodology which began in the third quarter of 2013. Previously, we used a look back period beginning in the third quarter of 2006 and a weighted average of losses. The impact of this change was immaterial to the allowance calculation.

	In addition to our ability to use our own historical loss data and migration between risk grades, we have a rigorous process for computing the qualitative factors that impact the ALL. A committee, independent of the historical loss migration team, reviews risk factors that may impact the ALL. Some factors are statistically quantifiable, such as concentration, growth, delinquency, and nonaccrual risk by loan type, while other factors are qualitative in nature, such as staff competency, competition within our markets and economic and regulatory changes impacting the loans held for investment.

	We lend primarily in North Carolina. As of September 30, 2013, a majority of the principal amount of the loans held for investment in our portfolio was to businesses and individuals in North Carolina. This geographic concentration subjects the loan portfolio to the general economic conditions within this area. The risks created by this concentration have been considered by management in the determination of the adequacy of the ALL. Management believes the ALL is adequate to cover estimated losses on loans at each balance sheet date.

	During the three month period ended September 30, 2013, we charged off $1.7 million in loans and realized $2.4 million in recoveries, for $0.7 million of net recoveries. During the nine month period ended September 30, 2013, we charged off $10.8 million in loans and realized $8.2 million in recoveries, for $2.6 million of net charge-offs. The majority of the loans charged off were loans that were previously impaired and had specific reserves assigned in prior periods.

	The ALL, as a percentage of loans held for investment, was 2.12% at September 30, 2013, compared to 2.51% at September 30, 2012. At December 31, 2012, the ALL, as a percentage of loans held for investment, was 2.49%.

	Risk Grades

	The risk-grade categories presented in the following table, which are standard categories used by the bank regulators, are:

	Pass - Loans categorized as Pass are higher quality loans that have adequate sources of repayment and little risk of collection.
	Special Mention - A Special Mention loan has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution's credit position at some future date. Special Mention loans are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

	Substandard - A Substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of Substandard loans, does not have to exist in individual assets classified Substandard.

	Doubtful - A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors, which may work to the advantage of strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans.
	Loans categorized as Special Mention or worse are considered Criticized. Loans categorized as Substandard or Doubtful are considered Classified. Purchased loans acquired in the Merger are recorded at estimated fair value on the date of acquisition without the carryover of related ALL. The table below includes $46.7 million and $60.6 million in Granite Purchased Loans categorized as Substandard or Doubtful at September 30, 2013 and December 31, 2012, respectively.

Loans included in the preceding loan composition table are net of participations sold. Loans are increased by net loan premiums and deferred loan discounts or fees of $2.5 million at September 30, 2013. Loans are increased by net deferred loan discounts or fees of $3.6 million at December 31, 2012.
At September 30, 2013, loans held for sale consisted of originated residential mortgage loans held for sale at the lower of cost or fair market value, as well as nonperforming commercial loans which are under contract to sell. At December 31, 2012, loans held for sale consisted only of originated residential mortgage loans.
Loans serviced for others are not included in the consolidated balance sheet. The unpaid principal balance of loans serviced for others amounted to $172.7 million at September 30, 2013 and $65.1 million at December 31, 2012.
Loans Pledged
To borrow from the FHLB, members must pledge collateral to secure advances and letters of credit. Acceptable collateral includes, among other types of collateral, a variety of residential, multifamily, home equity lines and second mortgages, and commercial loans. Gross loans of $215.5 million and $25.1 million of investment securities, and gross loans of $270.2 million were pledged to collateralize FHLB advances and letters of credit at September 30, 2013 and December 31, 2012, respectively, of which there was $15.7 million and $19.1 million of credit availability for borrowing, respectively. At September 30, 2013, $10.0 million of loans and $51.7 million of securities were pledged to collateralize potential borrowings from the Federal Reserve Discount Window, of which $57.5 million was available as borrowing capacity. We could also access $314.2 million of additional borrowings from the FHLB under credit lines by pledging additional collateral.
Nonaccruing and Impaired Loans
Interest income on loans is calculated by using the interest method based on the daily outstanding balance. The recognition of interest income is discontinued when, in management's opinion, the collection of all or a portion of interest becomes doubtful. Loans are returned to accrual status when the factors indicating doubtful collectability cease to exist and the loan has performed in accordance with its terms for a demonstrated period of time. The past due status of loans is based on the contractual payment terms. Had nonaccruing loans been on accruing status, interest income would have been higher by $0.7 million and $1.5 million for the three months ended September 30, 2013 and September 30, 2012, respectively, and higher by $2.3 million and $2.9 million for the nine months ended September 30, 2013 and September 30, 2012, respectively. At September 30, 2013 and December 31, 2012, COB had certain impaired loans of $51.1 million and $79.2 million, respectively, which were on nonaccruing interest status.
All loan classes are considered past due when the contractual amounts due with respect to principal and interest are not received within 30 days of the contractual due date. When we cannot reasonably expect full and timely repayment of its loan, the loan is placed on nonaccrual.
All loan classes on which principal or interest is in default for 90 days or more are put on nonaccrual status, unless there is sufficient documentation to conclude that the loan is well secured and in the process of collection. A debt is "well-secured" if collateralized by liens on or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt in full; or by the guarantee of a financially responsible party. A debt is "in process of collection" if collection is proceeding in due course either through legal action, including judgment enforcement procedures, or, in appropriate circumstances, through collection efforts not involving legal action that are reasonably expected to result in repayment of the debt or its restoration to a current status.
Loans that are less than 90 days delinquent may also be placed on nonaccrual if deterioration in the financial condition of the borrower has increased the probability of less than full repayment.
At the time a loan is placed on nonaccrual, all accrued, unpaid interest is charged off, unless it is documented that repayment of all principal and presently accrued but unpaid interest is probable. Charge-offs of accrued and unpaid interest are charged against the current year's interest income and not against the current ALL.
For all loan classes, a nonaccrual loan may be returned to accrual status when we can reasonably expect continued timely payments until payment in full. All prior arrearage does not have to be eliminated, nor do all previously charged-off amounts need to have been recovered, but the loan can still be returned to accrual status if the following conditions are met: (1) all principal and interest amounts contractually due (including arrearage) are reasonably assured of repayment within a reasonable period; and (2) there is a sustained period of repayment performance (generally a minimum of six months) by the borrower, in accordance with the contractual terms involving payments of cash or cash equivalents.
For all classes within all loan portfolios, cash receipts received on nonaccrual loans are applied entirely against principal until the loan or lease has been collected in full, after which time any additional cash receipts are recognized as interest income.
For all loan classes, as soon as any loan becomes uncollectible, the loan will be charged down or charged off as follows:

•	If unsecured, the loan must be charged off in full.

•	If secured, the outstanding principal balance of the loan should be charged down to the net liquidation value of the collateral.
Loans should be considered uncollectible when:

•	No regularly scheduled payment has been made within four months and the determination is made that any further payment is unlikely, or

•	The loan is unsecured, the borrower has filed for bankruptcy protection and there is no other (guarantor, etc.) support from an entity outside of the bankruptcy proceedings.
Based on a variety of credit, collateral and documentation issues, loans with lesser degrees of delinquency or obvious loss may also be deemed uncollectible.

All PI loans are considered to be accruing for all periods presented, in accordance with ASC 310-30.

A loan is considered impaired, based on current information and events, if it is probable that we will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. If the loan has been modified to provide relief to the borrower, the loan is deemed to be impaired if all principal and interest will not be repaid according to the original contract. All loans meeting the definition of Doubtful should be considered impaired.
When a loan has been determined to be impaired, the amount of the impairment is measured using the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, the observable market price of the loan, or the fair value of the collateral if the loan is collateral dependent. When the present value of expected future cash flows is used, the effective interest rate is the original contractual interest rate of the loan adjusted for any premium or discount. When the contractual interest rate is variable, the effective interest rate of the loan changes over time. A specific reserve is established as a component of the ALL when a loan has been determined to be impaired. Subsequent to the initial measurement of impairment, if there is a significant change to the impaired loan's expected future cash flows, or if actual cash flows are significantly different from the cash flows previously estimated, we recalculate the impairment and appropriately adjust the specific reserve. Similarly, if we measure impairment based on the observable market price of an impaired loan or the fair value of the collateral of an impaired collateral-dependent loan, we will adjust the specific reserve if there is a significant change in either of those bases.
When a loan is impaired and principal and interest is in doubt when contractually due, interest income is not recognized. Cash receipts received on nonaccruing impaired loans within any class are generally applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income. Cash receipts received on accruing impaired loans within any class are applied in the same manner as accruing loans that are not considered impaired.

Impaired loans also include loans for which we may elect to grant a concession, providing terms more favorable than those prevalent in the market (e.g., rate, amortization term), and formally restructure due to the weakening credit status of a borrower. Restructuring is designed to facilitate a repayment plan that minimizes the potential losses that we otherwise may have to incur. If these impaired loans are on nonaccruing status as of the date of restructuring, the loans are included in nonperforming loans. Nonperforming restructured loans will remain as nonperforming until the borrower can demonstrate adherence to the restructured terms for a period of no less than six months and when it is otherwise determined that continued adherence is reasonably assured. Some restructured loans continue as accruing loans after restructuring if the borrower is not past due at the time of restructuring, adequate collateral valuations support the restructured loans, and the cash flows of the underlying business appear adequate to support the restructured debt service. Not included in nonperforming loans are loans that have been restructured that were performing as of the restructure date. At September 30, 2013, there was $14.3 million in restructured loans, of which $6.7 million were accruing and in a performing status. At December 31, 2012, there was $20.8 million in restructured loans, of which $4.5 million were accruing and in a performing status.
Sale of Problem Loans
During 2012, we sold loans to third party buyers in order to reduce our problem loan exposure. These loans were transferred to loans held for sale at the time we received a signed contract for the purchase of the loans. Prior to transferring these loans to loans held for sale, the loans were marked down to the contract price less associated selling costs. All transactions were conducted at arm's length and loans were sold without recourse.

The following table presents sold loans by portfolio segment for the periods indicated below:

Granite Purchased Loans
Granite Purchased Loans include PI loans and PC loans. PC loans include performing revolving consumer and commercial loans on October 21, 2011, the acquisition date.
PI loans are segregated into pools and recorded at estimated fair value on the date of acquisition without the carryover of the related ALL. PI loans are accounted for under ASC 310-30 when the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition we will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the date of acquisition may include statistics such as past due status, nonaccrual status and risk grade. PI loans generally meet our definition for nonaccrual status; however, even if the borrower is not currently making payments, we will classify loans as accruing if we can reasonably estimate the amount and timing of future cash flows. All Granite Purchased PI loans are presented on an accruing basis. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference.
Periodically, we estimate the expected cash flows for each pool of the PI loans and evaluate whether the expected cash flows for each pool have changed from prior estimates. Decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges, or reclassification from nonaccretable difference to accretable yield with a positive impact on future interest income. Excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows.
We have elected to account for the Granite Purchased PI loans under ASC 310-30 and the Granite Purchased PC loans under ASC 310-20.
At September 30, 2013, and December 31, 2012, our financial statements reflected a PI loan ALL of $4.1 million and $5.4 million, respectively, and an ALL for PC loans of $0.7 million and $0.5 million, respectively.

During the three months ended September 30, 2013, we did not modify any loans. During the three months ended September 30, 2012, we modified one loan that was considered to be a troubled debt restructuring. We extended the term for this loan but did not modify the interest rate.
During the nine months ended September 30, 2013, we modified eleven loans that were considered to be troubled debt restructurings. We extended the terms for two of these loans, modified the interest rate for one of these loans, and modified the remaining eight loans in both ways. During the nine months ended September 30, 2012, we modified 20 loans that were considered to be troubled debt restructurings. We extended the terms for 16 of these loans, the interest rate was lowered for two of these loans, and the remaining two loans were modified for multiple reasons.
There were no loans restructured in the twelve months prior to September 30, 2013 that went into default during the three months or nine months ended September 30, 2013. There were also no loans restructured in the twelve months prior to September 30, 2012 that went into default during the three months or nine months ended September 30, 2012.
In the determination of the ALL, management considers troubled debt restructurings and any subsequent defaults in these restructurings as impaired loans. The amount of the impairment is measured using the present value of expected future cash flows discounted at the loan's effective interest rate, the observable market price of the loan, or the fair value of the collateral if the loan is collateral dependent.
Unfunded Commitments
The reserve for unfunded commitments, which is included in other liabilities, is calculated by determining the type of commitment and the remaining unfunded commitment for each loan. Based on the type of commitment, an expected usage percentage to the remaining unfunded balance is applied. The expected usage percentage is multiplied by the historical losses and qualitative and environmental factors for each loans pool as defined in the regular ALL calculation to determine the appropriate level of reserve. The following describes our method for determining the unfunded commitment:

•	Straight Lines of Credit - Unfunded balance of line of credit

•	Revolving Lines of Credit - Average Utilization (for the last 12 months) less Current Utilization

•	Letters of Credit - a 10% utilization is applied
The reserve for unfunded commitments was $0.5 million as of September 30, 2013 and $0.6 million at December 31, 2012.

	Other Real Estate Owned and Personal Property Acquired in Settlement of Loans
	OREO consists of real estate acquired through foreclosure or deed in lieu thereof. The property is classified as held for sale. The property is initially carried at fair value based on recent appraisals, less estimated costs to sell. Declines in the fair value of properties included in other real estate below carrying value are recognized by a charge to income.
	Total OREO and personal property acquired in settlement of loans decreased $30.0 million during the first nine months of 2013 from $63.1 million at December 31, 2012, to $33.2 million at September 30, 2013. This represents 39% of total nonperforming assets. At December 31, 2012, OREO and personal property acquired in settlement of loans represented 44% of total nonperforming assets.

	Earnings Per Share
	Basic net loss per share, or basic earnings/(loss) per share (“EPS”), is computed by dividing net loss to common shareholders by the weighted average number of common shares outstanding for the period. We retired our preferred stock in 2011.
	Diluted EPS reflects the potential dilution that could occur if COB's potential common stock, which consists of dilutive stock options and a common stock warrant, were issued. As required for entities with complex capital structures, a dual presentation of basic and diluted EPS is included on the face of the income statement, and a reconciliation of the numerator and denominator of the basic EPS computation to the numerator and denominator of the diluted EPS computation is provided in this note.

	During the three months and nine months ended September 30, 2013 and 2012, the price of the Company's common stock (as quoted on the Nasdaq Capital Market) was below the exercise price of all vested stock options and the common stock warrant. As a result, the options and warrants were considered antidilutive and thus are not included in the diluted share calculation. For the three months and nine months ended September 30, 2013, there were 23,197 antidilutive shares. For the three and nine months ended September 30, 2012, there were 23,347 antidilutive shares. Of the antidilutive shares, the number of shares relating to stock options were 1,125 for the three months and nine months ended September 30, 2013, and 1,275 for both the three months and nine months ended September 30, 2012, while the number relating to the warrant was 22,072 for all periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative and Financial Instruments	'
	Derivatives and Financial Instruments
	A derivative is a financial instrument that derives its cash flows, and therefore its value, by reference to an underlying instrument, index or referenced interest rate. These instruments include interest rate swaps, caps, floors, collars, options or other financial instruments designed to hedge exposures to interest rate risk or for speculative purposes.
	Accounting guidance requires an entity to recognize all derivatives as either assets or liabilities in the balance sheet, and measure those instruments at fair value. Changes in the fair value of those derivatives are reported in current earnings or other comprehensive income depending on the purpose for which the derivative is held and whether the derivative qualifies for hedge accounting.
	Mortgage banking derivatives used in the ordinary course of business consist of mandatory forward sales contracts or forward contracts and rate lock loan commitments. The fair value of our derivative instruments is primarily measured by obtaining pricing from broker-dealers recognized to be market participants.
	During 2012, we began originating residential mortgage loans for sale in the secondary market. We have established guidelines in originating, selling loans to Fannie Mae, and retaining or selling the loan servicing rights. The commitments to borrowers to originate residential mortgage loans and the forward sales commitments to investors are freestanding derivative instruments. As such, they do not qualify for hedge accounting treatment, and the fair value adjustments for these instruments is recorded through the Consolidated Statements of Operations in mortgage loan income. The fair market value of mortgage banking derivatives at September 30, 2013 was recorded in the consolidated balance sheet in Other Assets.

Fair Value Disclosures [Abstract]	'
Fair Values of Assets and Liabilities	'
	Fair Values of Assets and Liabilities
	We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale, derivative assets and liabilities, certain FHLB advances hedged by interest rate swaps designated as fair value hedges, performing mortgage loans held for sale, and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time-to-time, we may be required to record at fair value other assets and liabilities on a nonrecurring basis, such as non-performing loans held for sale, loans held for investment, impaired loans and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets or liabilities.
	Fair Value Hierarchy
	We group assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
	Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets.
	Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
	Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.
	The following is a description of valuation methodologies used for assets and liabilities recorded at fair value:
	Investments Securities Available-for-Sale
	Investment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 may include asset-backed securities in less liquid markets.
	Liquidity is a significant factor in the determination of the fair values of available-for-sale debt securities. Market price quotes may not be readily available for some positions, or positions within a market sector where trading activity has slowed significantly or ceased. Some of these instruments are valued using a discounted cash flow model, which estimates the fair value of the securities using internal credit risk, interest rate and prepayment risk models that incorporate management's best estimate of current key assumptions such as default rates, loss severity and prepayment rates. Principal and interest cash flows are discounted using an observable discount rate for similar instruments with adjustments that management believes a market participant would consider in determining fair value for the specific security. Underlying assets are valued using external pricing services, where available, or matrix pricing based on the vintages and ratings. Situations of illiquidity generally are triggered by the market's perception of credit uncertainty regarding a single company or a specific market sector. In these instances, fair value is determined based on limited available market information and other factors, principally from reviewing the issuer's financial statements and changes in credit ratings made by one or more ratings agencies.
	Loans Held for Sale
	Loans held for sale are carried at the lower of cost or fair value less estimated costs to sell. Once sold, the loans are beyond the reach of COB in all respects and the purchasing investor has all rights of ownership, including the ability to pledge or exchange the loans. Most of the loans sold are without recourse. Gains or losses on loan sales are recognized at the time of sale, are determined by the difference between net sales proceeds and the carrying value of the loan sold, and are included in Consolidated Statements of Operations. Since loans held for sale are carried at the lower of cost or fair value, the fair value of loans held for sale is based on contractual agreements with independent third-party buyers. As such, we classify loans held for sale subjected to nonrecurring fair value adjustments as Level 2.
	Loans Held for Investment
	We do not record loans held for investment at fair value on a recurring basis. However, from time to time, a loan is considered impaired and the related impairment is charged against the allowance or a specific allowance is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as impaired, management determines the fair value of the loan to quantify impairment, should such exist. The fair value of impaired loans is estimated using one of several methods, including collateral net liquidation value, market value of similar debt, enterprise value, and discounted cash flows. Those impaired loans not requiring a specific allowance represent loans for which the fair value of the expected repayments or collateral meet or exceed the recorded investments in such loans. At September 30, 2013 and December 31, 2012, substantially all of the total impaired loans were evaluated based on the fair value of the collateral. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. We record impaired loans as nonrecurring Level 3.
	Other Real Estate Owned
	OREO is adjusted to fair value upon transfer of the loans to OREO. Subsequently, OREO is carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is based upon independent market prices, appraised values of the collateral or management's estimation of the value of the collateral. Given the lack of observable market prices for identical properties, we record OREO as nonrecurring Level 3.
	Interest Rate Locks and Forward Loan Sale Commitments
	We enter into interest rate lock commitments and commitments to sell mortgages. The fair value of interest rate lock commitments is based on servicing rate premium, origination income net of origination costs, fall out rates and changes in loan pricing between the commitment date and the balance sheet date. We record interest rate lock commitments as recurring level 3, and based on their immaterial value, has excluded them from the fair value table.
	Mortgage Servicing Rights
	The fair value of mortgage serving rights (MSR) is dependent upon a number of assumptions including the fee per loan, the cost to service, the expected loan prepayment rate, and the discount rate. In determining the fair value of the existing MSR management reviews the key assumptions, analyzes pricing in the market for comparable MSR, and uses a third party provider to independently calculate the fair value of its MSR. We record mortgage servicing rights as recurring Level 3.
	Assets and Liabilities Recorded at Fair Value on a Recurring Basis
	Assets and liabilities carried at fair value on a recurring basis at September 30, 2013 for continuing operations are summarized in the following table:

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis
We may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with U.S. generally accepted accounting principles. These include assets that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period. This is due to further deterioration in the value of the assets.

Level 3 Valuation Methodologies. Following is a description of the unobservable inputs used for Level 3 fair value measurements.
Disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value is required. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time our entire holdings of a particular financial instrument.
Because no market exists for a portion of our financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
Fair Value of Financial Instruments
The following methods and assumptions were used to estimate the fair value for each class of COB's financial instruments.
Cash and cash equivalents. Fair value equals the carrying value of such assets due to their nature and is classified as Level 1.
Investment securities. The fair value of investment securities is based on quoted market prices, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. The fair value of equity investments in the restricted stock of the FRBR and FHLB approximates the carrying value. The fair value of investment securities is classified as Level 2.
Loans held for sale. Substantially all residential mortgage loans held for sale are pre-sold and their carrying value approximates fair value. We classified the fair value of loans held for sale as Level 2.
Loans held for investment. The fair value of fixed rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The fair value of variable rate loans with frequent repricing and negligible credit risk approximates book value. The fair value of loans is further discounted by credit and liquidity factors. We classified the fair value of loans as Level 3.
Accrued interest receivable and payable. The carrying amounts of accrued interest payable and receivable approximate fair value and are classified as Level 2 if the related asset or liability is classified as Level 2, or Level 3 if the related asset or liability is classified as Level 3.
Deposits. The fair value of noninterest-bearing and interest-bearing demand deposits and savings are the amounts payable on demand because these products have no stated maturity. The fair value of time deposits is estimated using the rates currently offered for deposits of similar remaining maturities and are classified as Level 2.
Borrowed funds. The carrying value of retail repurchase agreements is considered to be a reasonable estimate of fair value. The fair value of FHLB advances and other borrowed funds is estimated using the rates currently offered for advances of similar remaining maturities and is classified as Level 2. For the long term note payable, the current market rate for similar debt is substantially equal to the rate on this note, so its fair value approximates its carrying value.
Junior subordinated debentures. Included in junior subordinated debentures are variable rate trust preferred securities issued by COB. Fair values for the trust preferred securities were estimated by developing cash flow estimates for each of these debt instruments based on scheduled principal and interest payments and current interest rates. Once the cash flows were determined, a rate for comparable subordinated debt was used to discount the cash flows to the present value. The estimated fair value for our junior subordinated debentures have declined due to wider credit spreads (i.e., spread to LIBOR) on similar trust preferred issues. This is due, in part, to proposed bank regulatory changes in bank capital structure. We classified the fair value of junior subordinated debentures as Level 3.
Financial instruments with off-balance sheet risk. The fair value of financial instruments with off-balance sheet risk is considered to approximate carrying value, since the large majority of these future financing commitments would result in loans that have variable rates and/or relatively short terms to maturity. For other commitments, generally of a short-term nature, the carrying value is considered to be a reasonable estimate of fair value.
The estimated fair values of financial instruments for continuing operations are as follows at the periods indicated:

There were no transfers between valuation levels for any assets during the three and nine months ended September 30, 2013. If different valuation techniques are deemed necessary, we would consider those transfers to occur at the end of the period when the assets are valued.

Use of Estimates	'
	Use of Estimates
	We have made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these consolidated financial statements in conformity with accounting principles generally accepted in the United States ("GAAP"). Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowances for loan losses (“ALL”), estimated cash flows of purchased impaired loans, the carrying value of other real estate owned (“OREO”), the carrying value of intangible assets and the realization of deferred tax assets.
Reclassification	'
	Reclassification
	Certain reclassifications have been made to the prior period consolidated financial statements to place them on a comparable basis with the current period consolidated financial statements. These reclassifications have no effect on net income or shareholders' equity as previously reported.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	Comprehensive Income - In February 2013, the FASB issued ASU No. 2013-02 Comprehensive Income (Topic 220): "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income" (“ASU No. 2013-02”). This pronouncement requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income for each applicable component of net income, as well as a roll forward of the components of accumulated other comprehensive income on a prospective basis. This pronouncement is effective beginning January 1, 2013. The provisions of ASU No. 2013-02 relate only to financial statement presentation of other comprehensive income and, accordingly, its adoption did not have a material effect on COB's financial statements. These new disclosures appear in Note 10.
	FASB - From time to time, the Financial Accounting Standards Board (“FASB”) issues exposure drafts for proposed statements of financial accounting standards. Such exposure drafts are subject to comment from the public, to revisions by the FASB and to final issuance by the FASB as statements of financial accounting standards.
	Management considers the effect of the proposed statements on the consolidated financial statements of COB and monitors the status of changes to and proposed effective dates of exposure drafts. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on our financial position, results of operations or cash flows.
