	Note 1. Presentation of Financial Information
	Nature of Business-Cornerstone is a bank holding company whose primary business is performed by its wholly-owned subsidiary, Cornerstone Community Bank (the “Bank”). The Bank provides a full range of banking services to the Chattanooga, Tennessee market. The Bank has also established a loan production office in Dalton, Georgia to further enhance the Bank’s lending markets.
	Interim Financial Information (Unaudited)-The financial information in this report for September 30, 2014 and September 30, 2013 has not been audited. The information included herein should be read in conjunction with the annual consolidated financial statements and footnotes thereto included in the 2013 Annual Report to Shareholders which was furnished to each shareholder of Cornerstone in April of 2014. The consolidated financial statements presented herein conform to U.S. generally accepted accounting principles and to general industry practices. In the opinion of Cornerstone’s management, the accompanying interim financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial condition, the results of operations, and cash flows for the interim period. Results for interim periods are not necessarily indicative of the results to be expected for a full year.
	Use of Estimates-The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses, foreclosed assets and deferred tax assets.
	Consolidation-The accompanying consolidated financial statements include the accounts of Cornerstone and the Bank. Substantially all intercompany transactions, profits and balances have been eliminated.
	Reclassification-Certain amounts in the prior consolidated financial statements have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income, total assets or stockholders’ equity as previously reported.
	Accounting Policies-During interim periods, Cornerstone follows the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission. Since December 31, 2013, there have been no significant changes in any accounting principles or practices, or in the method of applying any such principles or practices, except for the following:
	In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers." This update is a joint project with the International Accounting Standards Board initiated to clarify the principles for recognizing revenue and to develop a common revenue standard that is meant to remove inconsistencies and weaknesses in revenue requirements, provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices, provide more useful information to users of financial statements and simplify the preparation of financial statements. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, "Revenue Recognition" and most industry-specific guidance throughout the Industry Topics of Codification. This update is effective for annual and interim periods beginning after December 15, 2016. Cornerstone does not believe this update will have a significant impact on the consolidated financial statements.
	Earnings per Common Share- Basic earnings per share (“EPS”) is computed by dividing income available to common shareholders (numerator) by the weighted average number of common shares outstanding during the period (denominator). Diluted EPS is computed by dividing income available to common shareholders (numerator) by the adjusted weighted average number of shares outstanding (denominator). The adjusted weighted average number of shares outstanding reflects the potential dilution occurring if securities or other contracts to issue common stock were exercised or converted into common stock resulting in the issuance of common stock that share in the earnings of the entity.
	The following is a summary of the basic and diluted earnings per share for the three and nine month periods ended September 30, 2014 and September 30, 2013.
		Three Months Ended September 30,
		2014		2013
	Net income available to common shareholders	$	12,845	$	35,703
	Weighted average common shares outstanding		6,627,398		6,547,074
	Effect of dilutive stock options		216,409		145,508
	Diluted shares		6,843,807		6,692,582
	Basic earnings per common share	$	0	$	0.01
	Diluted earnings per common share	$	0	$	0.01
		Nine Months Ended September 30,
		2014		2013
	Net income available to common shareholders	$	48,788	$	98,172
	Weighted average common shares outstanding		6,609,975		6,547,074
	Effect of dilutive stock options		180,197		127,453
	Diluted shares		6,790,172		6,674,527
	Basic earnings per common share	$	0.01	$	0.01
	Diluted earnings per common share	$	0.01	$	0.01
	For the three and nine months ended September 30, 2014 and 2013, the effects of outstanding antidilutive stock options are excluded from the computation of diluted earnings per common share because the exercise price of such options is higher than the market price. There are 222,435 and 503,075 antidilutive stock options as of September 30, 2014 and 2013, respectively.

	Note 2. Stock Based Compensation
	Accounting Policies- Cornerstone, as required by the FASB, applies the fair value recognition provisions of ASC 718, “Compensation –Stock Compensation.” For the nine month period ended September 30, 2014, $120,000 in compensation cost was charged to earnings related to the vested incentive stock options.
	Officer and Employee Plans-Cornerstone has two stock option plans under which officers and employees can be granted incentive stock options or non-qualified stock options to purchase a total of up to 1,420,000 shares of Cornerstone’s common stock. The exercise price for incentive stock options must be not less than 100 percent of the fair market value of the common stock on the date of the grant. The exercise price of the non-qualified stock options may be equal to or more or less than the fair market value of the common stock on the date of the grant. The incentive stock options vest 30 percent on the second anniversary of the grant date, 60 percent on the third anniversary of the grant date and 100 percent on the fourth anniversary of the grant date, and the non-qualified stock options vest 50 percent on the first anniversary of the grant date and 100 percent on the second anniversary of the grant date. The options expire ten years from the grant date. At September 30, 2014, the total remaining compensation cost to be recognized on non-vested options is approximately $686,000.
	A summary of the status of these stock option plans is presented in the following table:
						Weighted-

	Options exercisable at September 30, 2014		345,485	$	4.89
	Board of Directors Plan- Cornerstone has a stock option plan under which members of the Board of Directors, at the formation of the Bank, were granted options to purchase a total of up to 600,000 shares of common stock. Only non-qualified stock options may be granted under the Plan. In addition, members of the Board of Directors can be issued options under the Cornerstone 2002 Long-Term Incentive Plan to purchase up to 1,200,000 shares of Cornerstone stock. The options available for issuance to Board members under the 2002 Long-Term Incentive Plan are shared with officers and employees of Cornerstone. The exercise price of each option equals the market price of Cornerstone’s stock on the date of grant and the option’s maximum term is ten years, at which point they expire. Vesting for options granted are 50% on each of the first and second anniversary of the grant date with full vesting occurring at the second anniversary date. At September 30, 2014, the total remaining compensation cost to be recognized on non-vested options is approximately $146,000. A summary of the status of this stock option plan is presented in the following table:
						Weighted-
						Average

	Upon acquisition of a security, the Bank determines the appropriate impairment model that is applicable.  If the security is a beneficial interest in securitized financial assets, the Bank uses the beneficial interests in securitized financial assets impairment model.  If the security is not a beneficial interest in securitized financial assets, the Bank uses the debt and equity securities impairment model.  The Bank conducts periodic reviews to evaluate each security to determine whether an other-than-temporary impairment has occurred.  The Bank does not have any securities that have been classified as other-than-temporarily-impaired at September 30, 2014 or December 31, 2013.
	At September 30, 2014 and December 31, 2013, the categories of temporarily impaired securities, and management’s evaluation of those securities, are as follows:
State and municipal securities: At September 30, 2014, two investments in obligations of state and municipal securities had unrealized losses. The Bank believes the unrealized losses on those investments were caused by the interest rate environment and do not relate to the underlying credit quality of the issuers. Because the Bank has the intent and ability to hold those investments for a time necessary to recover their amortized cost bases, which may be until maturity, the Bank does not consider those investments to be other-than-temporarily impaired at September 30, 2014.
Mortgage-backed securities: At September 30, 2014, nineteen investments in residential mortgage-backed securities had unrealized losses.  This impairment is believed to be caused by the current interest rate environment.  The contractual cash flows of those investments are guaranteed by an agency of the U.S. Government.  Because the decline in market value is attributable to the current interest rate environment and not credit quality, and because the Bank does not intend to sell the investments and it is not more likely than not that the Bank will be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Bank does not deem those investments to be other-than-temporarily impaired at September 30, 2014.

	The following describe risk characteristics relevant to each of the portfolio segments:
	Real estate:
	As discussed below, Cornerstone offers various types of real estate loan products. All loans within this portfolio segment are particularly sensitive to the valuation of real estate:
		⋅	Commercial real estate-mortgage loans include owner-occupied commercial real estate loans and other commercial real estate loans. Owner-occupied commercial real estate loans to operating businesses are long-term financing of land and buildings. Other commercial real estate loans are generally secured by income producing properties.
		⋅	Consumer real estate-mortgage loans include loans secured by 1-4 family and multifamily residential properties. These loans are repaid by various means such as a borrower’s income, sale of the property, or rental income derived from the property.
		⋅	Construction and land development loans include extensions of credit to real estate developers or investors where repayment is dependent on the sale of the real estate or income generated from the real estate collateral. These loans are repaid through cash flow related to the operations, sale or refinance of the underlying property. This portfolio segment also includes owner-occupied construction loans for commercial businesses for the development of land or construction of a building. These loans are repaid by cash flow generated from the business operation. Real estate loans for income-producing properties such as apartment buildings, office and industrial buildings, and retail shopping centers are repaid from rent income derived from the properties.
	Commercial and industrial:
	The commercial and industrial loans include those loans to commercial customers for use in normal business operations to finance working capital needs, equipment purchases, or expansion projects. Loans are repaid by business cash flows. Collection risk in this portfolio is driven by the creditworthiness of the underlying borrower, particularly cash flows from the customers’ business operations.
	Consumer and other:
	The consumer loan portfolio segment includes direct consumer installment loans, overdrafts and other revolving credit loans, and educational loans. Loans in this portfolio are sensitive to unemployment and other key consumer economic measures.
	Cornerstone follows the loan impairment accounting guidance in ASC Topic 310. A loan is considered impaired when, based on current information and events, it is probable that Cornerstone will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans and loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in interest rates, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collections.
	The composition of loans by loan classification for impaired and performing loan status at September 30, 2014 and December 31, 2013, is summarized in the tables below (amounts in thousands):

Credit quality indicators:
Federal regulations require the Bank to review and classify its assets on a regular basis. To fulfill this requirement, the Bank systematically reviews its loan portfolio to ensure the Bank’s large loan relationships are being maintained within its loan policy guidelines, remain properly underwritten and are properly classified by loan grade. This review process is performed by the Bank's management, internal and external loan review, internal auditors, and state and federal regulators.
The Bank’s loan grading process is as follows:
	⋅	All loans are assigned a loan grade at the time of origination by the relationship manager. Typically, a loan is assigned a loan grade of “pass” at origination.
	⋅	Loan relationships greater than or equal to $500 thousand are reviewed by the Bank’s external loan review provider on an annual basis.
	⋅	Additionally, the Bank’s external loan review provider samples other loan relationships between $100 thousand and $500 thousand with an emphasis on commercial and commercial real estate loans and insider loans.
	⋅	The Bank’s internal loan review department samples approximately 33 percent of all other loan relationships less than $500 thousand on an annual basis for review.
	⋅	If a loan is delinquent 60 days or more or a pattern of delinquency exists, the loan will be selected for review.
	⋅	Generally, all loans on the Bank’s internal watchlist are reviewed annually by internal loan review or external loan review providers.
If a loan is classified as a problem asset, it will be assigned one of the following loan grades: substandard, doubtful, and loss. “Substandard” assets must have one or more defined weaknesses and are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. “Doubtful” assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss. An asset classified “loss” is considered uncollectible and of such little value that continuance as an asset of the institution is not warranted. The regulations also provide for a “special mention” category, described as assets which do not currently expose an institution to a sufficient degree of risk to warrant classification but do possess credit deficiencies or potential weaknesses deserving close attention. When the Bank classifies an asset as substandard or doubtful, a specific allowance for loan losses may be established.
The following tables outline the amount of each loan classification and the amount categorized into each risk rating as of September 30, 2014 and December 31, 2013 (amounts in thousands):

Impaired loans also include loans that the Bank has elected to formally restructure when, due to the weakening credit status of a borrower, the restructuring may facilitate a repayment plan that seeks to minimize the potential losses that the Bank may have to otherwise incur. At September 30, 2014 and December 31, 2013, the Bank has loans of approximately $4,802,000 and $5,753,000, respectively, that were modified in troubled debt restructurings. Troubled commercial loans are restructured by specialists within our Special Asset department and all restructurings are approved by committees and credit officers separate and apart from the normal loan approval process. These specialists are trained to reduce the Bank’s overall risk and exposure to loss in the event of a restructuring through obtaining either or all of the following: improved documentation, additional guaranties, increase in curtailments, reduction in collateral terms, additional collateral or other similar strategies.
There was one commercial real estate-mortgage loan with a pre-modification and post-modification outstanding recorded investment of $480,000 that was modified as a troubled debt restructuring during the nine month period ended September 30, 2014.
The following table presents a summary of loans that were modified as troubled debt restructurings during the nine month period ended September 30, 2013 (amounts in thousands):

	Note 5. Commitments and Contingent Liabilities
	Off Balance Sheet Arrangements - In the normal course of business, the Bank has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions; thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee.
	Standby letters of credit are generally issued on behalf of an applicant (our customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. A typical arrangement involves the applicant routinely being  indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions. The standby letter of credit would permit the beneficiary to obtain payment from the Bank under certain prescribed circumstances. Subsequently, the Bank would seek reimbursement from the applicant pursuant to the terms of the standby letter of credit.
	The Bank follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer’s creditworthiness is evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management’s credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment and personal property.
	The contractual amounts of these commitments are not reflected in the consolidated financial statements and would only be reflected if drawn upon. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should customers default on their resulting obligation to the Bank the maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those instruments.
	A summary of the Bank’s total contractual amount for all off-balance sheet commitments at September 30, 2014 is as follows:
	Commitments to extend credit	$	46.7 million
	Standby letters of credit	$	305 thousand
	Various legal claims also arise from time to time in the normal course of business. In the opinion of management, the resolution of claims outstanding at September 30, 2014 will not have a material effect on Cornerstone’s consolidated financial statements.

Fair Value Disclosures [Abstract]	'
Fair Value Disclosures [Text Block]	'
	Note 6. Fair Value Disclosures
	Fair Value Measurements:
	Cornerstone uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the “Fair Value Measurements and Disclosures” ASC Topic 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.
	ASC Topic 820 provides a consistent definition of fair value, which focuses on exit price in an orderly transaction between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.
	ASC Topic 820 also establishes a three-tier fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value, as follows:
	Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that Cornerstone has the ability to access.
	Level 2 - Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data.
	Level 3 - Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
	The following methods and assumptions were used by Cornerstone in estimating fair value disclosures for financial instruments. There have been no changes in the methodologies used at September 30, 2014 and December 31, 2013.
	Cash and cash equivalents:
	The carrying amounts of cash and cash equivalents approximate fair values based on the short-term nature of the assets. Cash and cash equivalents are classified as Level 1 of the fair value hierarchy.
	Securities:
	Fair values are estimated using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, and credit spreads. Securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs.
	The carrying value of Federal Home Loan Bank stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank. Federal Home Loan Bank stock is classified as Level 3 of the fair value hierarchy.
	Loans:
	For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for fixed-rate loans are estimated using discounted cash flow analysis, using market interest rates for comparable loans. 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 individually impaired, management measures impairment in accordance with ASC Topic 310, “Accounting by Creditors for Impairment of a Loan.” The fair value of impaired loans is estimated using several methods including collateral value, liquidation value and discounted cash flows.
	Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At September 30, 2014, substantially all of the total impaired loans were evaluated based on the fair value of collateral. The remaining impaired loans were evaluated based on a discounted cash flow methodology. In accordance with ASC Topic 820, these impaired loans with a valuation allowance require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, Cornerstone records the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value or is based on a discounted cash flow methodology and there is no observable market price, Cornerstone records the impaired loan as nonrecurring Level 3. At December 31, 2013, impaired loans were evaluated based on the fair value of collateral and on the discounted cash flow methodology.
	Foreclosed assets:
	Foreclosed assets, consisting of properties obtained through foreclosure or in satisfaction of loans, is initially recorded at fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, adjusted for estimated selling costs. At the time of foreclosure, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the allowance for loan losses. Gains or losses on sale and any subsequent adjustment to the fair value are recorded as a component of foreclosed assets expense. Foreclosed assets are included in Level 2 of the valuation hierarchy.
	Deposits:
	The fair value of deposits with no stated maturity, such as noninterest-bearing and interest-bearing demand deposits, savings deposits, and money market accounts, is equal to the amount payable on demand at the reporting date. The carrying amounts of variable-rate, fixed-term certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies market interest rates on comparable instruments to a schedule of aggregated expected monthly maturities on time deposits. Generally, Level 3 inputs are utilized in this estimate.
	Federal funds purchased and securities sold under agreements to repurchase:
	The carrying amount of these liabilities approximates their estimated fair value. These liabilities are included in Level 3 of the fair value hierarchy.
	Federal Home Loan Bank advances and other borrowings:
	The fair value of these fixed rate advances is estimated based on discounted contractual cash flows using current incremental borrowing rates for similar type borrowing arrangements. These liabilities are included in Level 3 of the fair value hierarchy.
	Accrued interest:
	The carrying amounts of accrued interest approximate fair value. Accrued interest is included in Level 3 of the fair value hierarchy.
	Commitments to extend credit, letters of credit and lines of credit:
	The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates.
	Assets and liabilities recorded at fair value on a recurring basis are as follows.

	Cornerstone has no assets or liabilities whose fair values are measured on a recurring basis using Level 3 inputs. Additionally, there were no transfers between Level 1 and Level 2 in the fair value hierarchy.
	Certain assets and liabilities are measured at fair value on a nonrecurring basis, which means the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The tables below present information about assets and liabilities on the balance sheet at September 30, 2014 and December 31, 2013 for which a nonrecurring change in fair value was recorded (amounts in thousands).

Accounting Policies [Abstract]	'
Interim Financial Information Policy [Policy Text Block]	'
	Interim Financial Information (Unaudited)-The financial information in this report for September 30, 2014 and September 30, 2013 has not been audited. The information included herein should be read in conjunction with the annual consolidated financial statements and footnotes thereto included in the 2013 Annual Report to Shareholders which was furnished to each shareholder of Cornerstone in April of 2014. The consolidated financial statements presented herein conform to U.S. generally accepted accounting principles and to general industry practices. In the opinion of Cornerstone’s management, the accompanying interim financial statements contain all material adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial condition, the results of operations, and cash flows for the interim period. Results for interim periods are not necessarily indicative of the results to be expected for a full year.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates-The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses, foreclosed assets and deferred tax assets.
Consolidation, Policy [Policy Text Block]	'
	Consolidation-The accompanying consolidated financial statements include the accounts of Cornerstone and the Bank. Substantially all intercompany transactions, profits and balances have been eliminated.
Reclassification, Policy [Policy Text Block]	'
	Reclassification-Certain amounts in the prior consolidated financial statements have been reclassified to conform to the current period presentation. The reclassifications had no effect on net income, total assets or stockholders’ equity as previously reported.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Accounting Policies-During interim periods, Cornerstone follows the accounting policies set forth in its Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission. Since December 31, 2013, there have been no significant changes in any accounting principles or practices, or in the method of applying any such principles or practices, except for the following:
	In May 2014, the FASB issued Accounting Standards Update 2014-09, "Revenue from Contracts with Customers." This update is a joint project with the International Accounting Standards Board initiated to clarify the principles for recognizing revenue and to develop a common revenue standard that is meant to remove inconsistencies and weaknesses in revenue requirements, provide a more robust framework for addressing revenue issues, improve comparability of revenue recognition practices, provide more useful information to users of financial statements and simplify the preparation of financial statements. The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, "Revenue Recognition" and most industry-specific guidance throughout the Industry Topics of Codification. This update is effective for annual and interim periods beginning after December 15, 2016. Cornerstone does not believe this update will have a significant impact on the consolidated financial statements.
Earnings Per Share, Policy [Policy Text Block]	'
	Earnings per Common Share- Basic earnings per share (“EPS”) is computed by dividing income available to common shareholders (numerator) by the weighted average number of common shares outstanding during the period (denominator). Diluted EPS is computed by dividing income available to common shareholders (numerator) by the adjusted weighted average number of shares outstanding (denominator). The adjusted weighted average number of shares outstanding reflects the potential dilution occurring if securities or other contracts to issue common stock were exercised or converted into common stock resulting in the issuance of common stock that share in the earnings of the entity.
	The following is a summary of the basic and diluted earnings per share for the three and nine month periods ended September 30, 2014 and September 30, 2013.
		Three Months Ended September 30,

	Diluted earnings per common share	$	0.01	$	0.01
	For the three and nine months ended September 30, 2014, the effects of outstanding antidilutive stock options are excluded from the computation of diluted earnings per common share because the exercise price of such options are higher than the market price. There are 222,435 and 503,075 antidilutive stock options as of September 30, 2014 and 2013, respectively.

Description Of Bank's Loan Grading Process	'The Banks loan grading process is as follows: All loans are assigned a loan grade at the time of origination by the relationship manager. Typically, a loan is assigned a loan grade of pass at origination. Loan relationships greater than or equal to $500 thousand are reviewed by the Banks external loan review provider on an annual basis. Additionally, the Banks external loan review provider samples other loan relationships between $100 thousand and $500 thousand with an emphasis on commercial and commercial real estate loans and insider loans. The Banks internal loan review department samples approximately 33 percent of all other loan relationships less than $500 thousand on an annual basis for review. If a loan is delinquent 60 days or more or a pattern of delinquency exists, the loan will be selected for review. Generally, all loans on the Banks internal watchlist are reviewed annually by internal loan review or external loan review providers.	'	'	'
