Basis of Presentation and Summary of Significant Accounting Policies	'
	Note 1 – Basis of Presentation and Summary of Significant Accounting Policies
	Basis of Presentation – The consolidated financial statements include Porter Bancorp, Inc. (Company or PBI) and its subsidiary, PBI Bank (Bank). The Company owns a 100% interest in the Bank. All significant inter-company transactions and accounts have been eliminated in consolidation.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the entire year. A description of other significant accounting policies is presented in the notes to the Consolidated Financial Statements for the year ended December 31, 2013 included in the Company’s Annual Report on Form 10-K.
	Use of Estimates – To prepare financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, fair values of financial instruments, stock compensation, deferred tax assets, other intangibles, and fair values of other real estate owned are particularly subject to change.
	Reclassifications – Some items in the prior year financial statements were reclassified to conform to the current presentation. The reclassifications did not impact net income (loss) or stockholders’ equity.

Going Concern Considerations and Future Plans	'
	Note 2 – Going Concern Considerations and Future Plans
	The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business for the foreseeable future. However, the events and circumstances described in this Note create substantial doubt about the Company’s ability to continue as a going concern.
	During the first three months of 2014, we reported net loss attributable to common shareholders of $976,000, compared with net loss attributable to common shareholders of $524,000 for the first three months of 2013. The increase in net loss in 2014 compared to 2013 is primarily attributable to declining interest income driven by the sizeable reduction in our loan portfolio and the absence of income from fiduciary activities in the current quarter compared to $517,000 in the first quarter of 2013 as we curtailed providing trust services early in 2013.
	At March 31, 2014, we continued to be involved in various legal proceedings in which we dispute the material factual allegations. After conferring with our legal advisors, we believe we have meritorious grounds on which to prevail. If we do not prevail, the ultimate outcome of any one of these matters could have a material adverse effect on our financial condition, results of operations, or cash flows. These matters are more fully described in Note 13 – “Contingencies”.
	For the year ended December 31, 2013, we reported a net loss to common shareholders of $3.4 million, compared to a net loss to common shareholders of $33.4 million for the year ended December 31, 2012. This loss coupled with the comprehensive loss for the year reduced shareholders equity to $35.9 million, from $47.2 million at the end of 2012. This reduction was attributable primarily to OREO expense of $4.5 million resulting from fair value write-downs driven by new appraisals and reduced marketing prices, net loss on sales, and ongoing operating expense, along with $4.7 million in loan collection expenses. The reduction was also attributable to a reduction in the fair value of securities of $8.4 million, net, as well as the accrual of dividends and accretion to preferred shareholders of $2.1 million. We also had lower net interest margin due to lower average loans outstanding, loans re-pricing at lower rates, and the level of non-performing loans in our portfolio.
	In the fourth quarter of 2011 we began deferring interest payments on our junior subordinated notes, which resulted in a deferral of distributions on our trust preferred securities. If we cannot pay all unpaid deferred distributions on our trust preferred securities for more than twenty consecutive quarters, we will be in default, and the holders of our trust preferred securities would become entitled to payment of the full amount of outstanding principal plus accrued and unpaid interest. At March 31, 2014, cumulative accrued and unpaid interest on our junior subordinated notes totaled $1.7 million. Future cash dividends on our common stock are subject to the prior payment of all deferred distributions on our trust preferred securities.
	In June 2011, the Bank agreed to a Consent Order with the FDIC and KDFI in which the Bank agreed, among other things, to improve asset quality, reduce loan concentrations, and maintain a minimum Tier 1 leverage ratio of 9% and a minimum total risk based capital ratio of 12%. The Consent Order was included in our Current Report on 8-K filed on June 30, 2011. In October 2012, the Bank entered into a new Consent Order with the FDIC and KDFI again agreeing to maintain a minimum Tier 1 leverage ratio of 9% and a minimum total risk based capital ratio of 12%. The Bank also agreed that if it should be unable to reach the required capital levels, and if directed in writing by the FDIC, then the Bank would within 30 days develop, adopt and implement a written plan to sell or merge itself into another federally insured financial institution or otherwise immediately obtain a sufficient capital investment into the Bank to fully meet the capital requirements.
	We expect to continue to work with our regulators toward capital ratio compliance as outlined in the written capital plan previously submitted by the Bank. The new Consent Order also requires the Bank to continue to adhere to the plans implemented in response to the June 2011 Consent Order, and includes the substantive provisions of the June 2011 Consent Order. The new Consent Order was included in our Current Report on 8-K filed on September 19, 2012. As of March 31, 2014, the capital ratios required by the Consent Order were not met.
	In order to meet these capital requirements, the Board of Directors and management are continuing to evaluate strategies to achieve the following objectives:
		•	Increasing capital through a possible public offering or private placement of common stock to new and existing shareholders. We have engaged a financial advisor to assist our Board in evaluating our options for increasing capital and redeeming our Series A Preferred Stock.
		•	Continuing to operate the Company and Bank in a safe and sound manner. This strategy may require us to reduce our lending concentrations, remediate non-performing loans, and reduce other noninterest expense through the disposition of OREO.
		•	Management succession and adding resources to the management team. John T. Taylor succeeded Maria Bouvette as CEO for PBI Bank in 2012 and CEO of the Company in 2013. In addition, we appointed new executives to lead key functions of our banking operations. John R. Davis became Chief Credit Officer of PBI Bank in 2012, with responsibility for establishing and executing credit quality policies and overseeing credit administration for the organization. We have also augmented our staffing in the commercial lending area, now led by Joe C. Seiler.
		•	Evaluating our internal processes and procedures, distribution of labor, and work-flow to ensure we have adequately and appropriately deployed resources in an efficient manner in the current environment.
		•	Executing on our commitment to improve credit quality and reduce loan concentrations and balance sheet risk.
		¡	We have reduced the size of our loan portfolio significantly from $1.3 billion at December 31, 2010 to $682.6 million at March 31, 2014.
		¡	Our Consent Order calls for us to reduce our construction and development loans to not more than 75% of total risk-based capital. We have now been in compliance for eight quarters. Construction and development loans totaled $41.8 million, or 50% of total risk-based capital, at March 31, 2014, down from $43.3 million, or 52% of total risk-based capital, at December 31, 2013.
		¡	Our Consent Order also requires us to reduce non-owner occupied commercial real estate loans, construction and development loans, and multi-family residential real estate loans as a group, to not more than 250% of total risk-based capital. While we have made significant progress, we were not in compliance with this concentration limit at March 31, 2014. These loans totaled $226.9 million, or 273% of total risk-based capital, at March 31, 2014 and $237.0 million, or 284% of total risk-based capital, at December 31, 2013.
		¡	We have reduced the construction loan portfolio from $199.5 million at December 31, 2010 to $41.8 million at March 31, 2014. Our non-owner occupied commercial real estate loans declined from $293.3 million at December 31, 2010 to $146.4 million at March 31, 2014.
		•	Executing on our commitment to sell other real estate owned and reinvest in quality income producing assets.
		¡	The remediation process for loans secured by real estate has led the Bank to acquire significant levels of OREO since 2010. The Bank acquired $20.6 million, $33.5 million, $41.9 million, and $90.8 million during 2013, 2012, 2011, and 2010, respectively. For the three months ended March 31, 2014, we acquired $17.4 million of OREO.
		¡	We have incurred significant losses in disposing of this real estate. We incurred losses totaling $2.6 million, $9.3 million, $42.8 million, and $13.9 million in 2013, 2012, 2011, and 2010, respectively, from sales at less than carrying values and fair value write-downs attributable to declines in appraisal valuations and changes in our pricing strategies. During the three months ended March 31, 2014, we incurred OREO losses totaling $250,000 from declining values as evidenced by new appraisals and reduced marketing prices in connection with our sales strategies.
		¡	To ensure we maximize the value we receive upon the sale of OREO, we continually evaluate sales opportunities. Proceeds from the sale of OREO totaled $2.1 million during the three months ended March 31, 2014 and $30.8 million, $22.5 million, $26.0 million and $25.0 million during the years ended December 31, 2013, 2012, 2011, and 2010, respectively.
		¡	At December 31, 2013, the OREO portfolio consisted of 62% construction, development, and land assets. At March 31, 2014, this concentration decreased to 42%; however, the balance increased from $19.2 million to $19.4 million. Commercial real estate represents 16% of the OREO portfolio at March 31, 2014 compared with 19% at December 31, 2013. 1-4 family residential properties represent 25% of the OREO portfolio at March 31, 2014 compared with 16% at December 31, 2013, and multi-family properties represent 15% of the OREO portfolio at March 31, 2014, compared to 1% at December 31, 2013.
	Bank regulatory agencies can exercise discretion when an institution does not meet the terms of a consent order. Based on individual circumstances, the agencies may issue mandatory directives, impose monetary penalties, initiate changes in management, or take more serious adverse actions.

The Company evaluates securities for other than temporary impairment (OTTI) on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Consideration is given to the length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, underlying credit quality of the issuer, and the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, the sector or industry trends and cycles affecting the issuer, and the results of reviews of the issuer’s financial condition. Management currently intends to hold all securities with unrealized losses until recovery, which for fixed income securities may be at maturity. As of March 31, 2014, management does not believe securities within our portfolio with unrealized losses should be classified as other than temporarily impaired.

Troubled Debt Restructuring
A troubled debt restructuring (TDR) occurs when the Company has agreed to a loan modification in the form of a concession for a borrower who is experiencing financial difficulty. The majority of the Company’s TDRs involve a reduction in interest rate, a deferral of principal for a stated period of time, or an interest only period. All TDRs are considered impaired and the Company has allocated reserves for these loans to reflect the present value of the concessionary terms granted to the borrower.
The following table presents the types of TDR loan modifications by portfolio segment outstanding as of March 31, 2014 and December 31, 2013:

Total TDRs	$	44,346		$	46,916		$	91,262
At March 31, 2014 and December 31, 2013, 58% and 49%, respectively, of the Company’s TDRs were performing according to their modified terms. The Company allocated $2.2 million and $2.9 million in reserves to borrowers whose loan terms have been modified in TDRs as of March 31, 2014, and December 31, 2013, respectively. The Company has committed to lend additional amounts totaling $262,000 and $261,000 as of March 31, 2014 and December 31, 2013, respectively, to borrowers with outstanding loans classified as TDRs.
No TDR loan modifications occurred during the three months ended March 31, 2014. The following tables present a summary of the types of TDR loan modifications by portfolio type that occurred during the three months ended March 31, 2013:

No TDR loan modifications occurred during the three months ended March 31, 2014. As of March 31, 2013, 63% of the Company’s TDRs that occurred during the three months ended March 31, 2013 were performing according to their modified terms. The Company allocated $203,000 in reserves to borrowers whose loan terms have been modified during the three months ended March 31, 2013. For modifications occurring during the three month period ended March 31, 2013, the post-modification balances approximate the pre-modification balances.
During the first three months of 2014, no TDRs defaulted on their restructured loan within the 12 month period following the loan modification. A default is considered to have occurred once the TDR is past due 90 days or more or it has been placed on nonaccrual. During the first three months of 2013, approximately $1.6 million TDRs defaulted on their restructured loan within the 12 month period following the loan modification. These defaults consisted of $1.5 million in commercial real estate loans and $86,000 in consumer loans.
Nonperforming Loans
Nonperforming loans include impaired loans not on accrual and smaller balance homogeneous loans, such as residential mortgage and consumer loans, that are collectively evaluated for impairment.
The following table presents the recorded investment in nonaccrual and loans past due 90 days and still on accrual by class of loan as of March 31, 2014, and December 31, 2013:

Credit Quality Indicators
We categorize loans into risk categories at origination based upon original underwriting. Thereafter, we categorize loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Loans are analyzed individually by classifying the loans as to credit risk. This analysis includes loans with an outstanding balance greater than $500,000 and non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a quarterly basis. We have no non-rated loans. The following definitions are used for risk ratings:
Watch – Loans classified as watch are those loans which have experienced a potentially adverse development which necessitates increased monitoring.
Special Mention – Loans classified as special mention do not have all of the characteristics of substandard or doubtful loans. They have one or more deficiencies which warrant special attention and which corrective action, such as accelerated collection practices, may remedy.
Substandard – Loans classified as substandard are those loans with clear and defined weaknesses such as a highly leveraged position, unfavorable financial ratios, uncertain repayment sources or poor financial condition which may jeopardize the repayment of the debt as contractually agreed. They are characterized by the distinct possibility we will sustain some losses if the deficiencies are not corrected.
Doubtful – Loans classified as doubtful are those loans which have characteristics similar to substandard loans but with an increased risk that collection or liquidation in full is highly questionable and improbable.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be “Pass” rated loans. As of March 31, 2014, and December 31, 2013, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows:
	Pass			Watch			Special			Substandard			Doubtful			Total

During the first quarter of 2014, management instituted a new risk category within its pass classification. The purpose was to better identify certain loans where the borrower’s sustained satisfactory repayment history was deemed a more relevant predictor of future loss than certain underwriting criteria at origination. The establishment of this new pass risk category helps to ensure the watch risk category remains transitory and event driven in nature. A total of $24.2 million in commercial, $8.5 million in residential, and $2.2 million in agriculture loans were reclassified from watch to the new pass risk category during the quarter.

Other Real Estate Owned	'
	Note 5 – Other Real Estate Owned
	Other real estate owned (OREO) is real estate acquired as a result of foreclosure or by deed in lieu of foreclosure. It is classified as real estate owned until such time as it is sold. When property is acquired as a result of foreclosure or by deed in lieu of foreclosure, it is recorded at its fair market value less cost to sell. Any write-down of the property at the time of acquisition is charged to the allowance for loan losses. Subsequent reductions in fair value are recorded as non-interest expense.
	To determine the fair value of OREO for smaller dollar single family homes, we consult with internal real estate sales staff and external realtors, investors, and appraisers. If the internally evaluated market price is below our underlying investment in the property, appropriate write-downs are taken. For larger dollar residential and commercial real estate properties, we obtain a new appraisal of the subject property in connection with the transfer to other real estate owned. We typically obtain updated appraisals each year on the anniversary date of ownership unless a sale is imminent.
	The following table presents the major categories of OREO at the period-ends indicated:

Fair Values Measurement	'
	Note 8 – Fair Values Measurement
	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We use various valuation techniques to determine fair value, including market, income and cost approaches. There are three levels of inputs that may be used to measure fair values:
	Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets an entity has the ability to access as of the measurement date, or observable inputs.
	Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, 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 an entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. When that occurs, we classify the fair value hierarchy on the lowest level of input that is significant to the fair value measurement. We used the following methods and significant assumptions to estimate fair value.
	Securities: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges, if available. This valuation method is classified as Level 1 in the fair value hierarchy. For securities where quoted prices are not available, fair values are calculated on market prices of similar securities, or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities. Matrix pricing relies on the securities’ relationship to similarly traded securities, benchmark curves, and the benchmarking of like securities. Matrix pricing utilizes observable market inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. In instances where broker quotes are used, these quotes are obtained from market makers or broker-dealers recognized to be market participants. This valuation method is classified as Level 2 in the fair value hierarchy. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators. This valuation method is classified as Level 3 in the fair value hierarchy. Discounted cash flows are calculated using spread to swap and LIBOR curves that are updated to incorporate loss severities, volatility, credit spread and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations.
	Impaired Loans: An impaired loan is evaluated at the time the loan is identified as impaired and is recorded at fair value less costs to sell. Fair value is measured based on the value of the collateral securing the loan and is classified as Level 3 in the fair value hierarchy. Fair value is determined using several methods. Generally, the fair value of real estate is determined based on appraisals by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.
	Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. These routine adjustments are made to adjust the value of a specific property relative to comparable properties for variations in qualities such as location, size, and income production capacity relative to the subject property of the appraisal. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value.
	We routinely apply an internal discount to the value of appraisals used in the fair value evaluation of our impaired loans. The deductions to the appraisal take into account changing business factors and market conditions, as well as potential value impairment in cases where our appraisal date predates a likely change in market conditions. These deductions range from 10% for routine real estate collateral to 25% for real estate that is determined (1) to have a thin trading market or (2) to be specialized collateral. This is in addition to estimated discounts for cost to sell of six to ten percent.
	We also apply discounts to the expected fair value of collateral for impaired loans where the likely resolution involves litigation or foreclosure. Resolution of this nature generally results in receiving lower values for real estate collateral in a more aggressive sales environment. We have utilized discounts ranging from 10% to 33% in our impairment evaluations when applicable.
	Impaired loans are evaluated quarterly for additional impairment. We obtain updated appraisals on properties securing our loans when circumstances are warranted such as at the time of renewal or when market conditions have significantly changed. This determination is made on a property-by-property basis in light of circumstances in the broader economic climate and our assessment of deterioration of real estate values in the market in which the property is located. The first stage of our assessment involves management’s inspection of the property in question. Management also engages in conversations with local real estate professionals, investors, and market makers to determine the likely marketing time and value range for the property. The second stage involves an assessment of current trends in the regional market. After thorough consideration of these factors, management will either internally evaluate fair value or order a new appraisal.
	Other Real Estate Owned (OREO): OREO is evaluated at the time of acquisition and recorded at fair value as determined by independent appraisal or internal market evaluation less cost to sell. Our quarterly evaluations of OREO for impairment are driven by property type. For smaller dollar single family homes, we consult with internal real estate sales staff and external realtors, investors, and appraisers. Based on these consultations, we determine asking prices for OREO properties we are marketing for sale. If the internally evaluated fair value is below our recorded investment in the property, appropriate write-downs are taken.
	For larger dollar commercial real estate properties, we obtain a new appraisal of the subject property in connection with the transfer to other real estate owned. In some of these circumstances, an appraisal is in process at quarter end, and we must make our best estimate of the fair value of the underlying collateral based on our internal evaluation of the property, review of the most recent appraisal, and discussions with the currently engaged appraiser. We obtain updated appraisals on the anniversary date of ownership unless a sale is imminent.
	We routinely apply an internal discount to the value of appraisals used in the fair value evaluation of our OREO. The deductions to the appraisal take into account changing business factors and market conditions, as well as potential value impairment in cases where our appraisal date predates a likely change in market conditions. These deductions range from 10% for routine real estate collateral to 25% for real estate that is determined (1) to have a thin trading market or (2) to be specialized collateral. This is in addition to estimated discounts for cost to sell of six to ten percent.

Impaired loans, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a carrying amount of $107.6 million at March 31, 2014 with a valuation allowance of $2.5 million. This resulted in no additional provision for loan losses for the three months ended March 31, 2014. At December 31, 2013, impaired loans had a carrying amount of $132.2 million, with a valuation allowance of $3.5 million.
Other real estate owned, which is measured at the lower of carrying or fair value less estimated costs to sell, had a net carrying amount of $45.9 million as of March 31, 2014, compared with $30.9 million at December 31, 2013. Fair value write-downs of $250,000 were recorded on other real estate owned for the three months ended March 31, 2014.

The methods and assumptions, not previously presented, used to estimate fair values are described as follows:
(a) Cash and Cash Equivalents
The carrying amounts of cash and short-term instruments approximate fair values and are classified as either Level 1 or Level 2. Non-interest bearing deposits are Level 1 whereas interest bearing due from bank accounts and fed funds sold are Level 2.
(b) FHLB Stock
It is not practical to determine the fair value of FHLB stock due to restrictions placed on its transferability.
(c) Loans, Net
Fair values of loans, excluding loans held for sale, are estimated as follows: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price.
(d) Mortgage Loans Held for Sale
The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.
(e) Deposits
The fair values disclosed for non-interest bearing deposits are, by definition, equal to the amount payable on demand at the reporting date resulting in a Level 1 classification. The carrying amounts of variable rate interest bearing deposits approximate their fair values at the reporting date resulting in a Level 2 classification. Fair values for fixed rate interest bearing deposits are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification.
(f) Securities Sold Under Agreements to Repurchase
The carrying amounts of borrowings under repurchase agreements approximate their fair values resulting in a Level 2 classification.
(g) Other Borrowings
The fair values of the Company’s FHLB advances are estimated using discounted cash flow analyses based on the current borrowing rates resulting in a Level 2 classification.
The fair values of the Company’s subordinated capital notes and junior subordinated debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification.
(h) Accrued Interest Receivable/Payable
The carrying amounts of accrued interest approximate fair value resulting in a Level 2 or Level 3 classification based on the level of the asset or liability with which the accrual is associated.

In analyzing future taxable income levels, we considered all evidence currently available, both positive and negative. Based on our analysis, we continue to maintain a valuation allowance for all deferred tax assets as of March 31, 2014. Our deferred tax assets and the related valuation allowance are analyzed and adjusted on a quarterly basis.
	The Company does not have any beginning and ending unrecognized tax benefits. The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next twelve months. There were no interest and penalties recorded in the income statement or accrued for the three months ended March 31, 2014 or the year ended December 31, 2013 related to unrecognized tax benefits.
	The Company and its subsidiaries are subject to U.S. federal income tax and the Company is subject to income tax in the Commonwealth of Kentucky. The Company is no longer subject to examination by taxing authorities for years before 2010.

Stock Plans and Stock Based Compensation	'
	Note 10 – Stock Plans and Stock Based Compensation
	The Company has two stock incentive plans. On February 23, 2006, the Company adopted the Porter Bancorp, Inc. 2006 Stock Incentive Plan. In May 2013, shareholders approved an amendment to the plan to increase the number of shares authorized for issuance by 800,000 shares. The 2006 Plan now permits the issuance of up to 1,263,050 shares of the Company’s common stock upon the exercise of stock options or upon the grant of stock awards. As of March 31, 2014, the Company had granted 831,163 unvested shares net of forfeitures and vesting under the stock incentive plan. Shares issued under the plan vest annually on the anniversary date of the grant over three to ten years. The Company has 295,763 shares remaining available for issue under the plan.
	On May 15, 2006, the Board of Directors approved the Porter Bancorp, Inc. 2006 Non-Employee Directors Stock Ownership Incentive Plan, which was approved by holders of the Company’s voting common stock on June 8, 2006. On May 16, 2012, holders of the Company’s voting common stock voted to further amend the 2006 Non-Employee Directors Stock Ownership Incentive Plan to award restricted shares having a fair market value of $25,000 annually to each non-employee director, and to increase the number of shares issuable under the Directors’ Plan from 100,000 shares to 400,000 shares. Unvested shares are granted automatically under the plan at fair market value on the date of grant and vest on December 31 in the year of grant.
	To date, the Company has issued 47,428 unvested shares, net of forfeitures and vesting, to non-employee directors. At March 31, 2014, 113,362 shares remain available for issuance under this plan.
	The fair value of the 2014 unvested shares issued to employees was $52,000, or $0.96 per weighted-average share. The Company recorded $133,000 and $103,000 of stock-based compensation during the first three months of 2014 and 2013, respectively, to salaries and employee benefits. There was no significant impact on compensation expense resulting from forfeited or expiring shares. We expect substantially all of the unvested shares outstanding at the end of the period will vest according to the vesting schedule. No deferred tax benefit was recognized related to this expense for either period.

Capital Requirements and Restrictions on Retained Earnings	'
	Note 12 – Capital Requirements and Restrictions on Retained Earnings
	Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.
	On June 24, 2011, PBI Bank entered into a Consent Order with the FDIC and the Kentucky Department of Financial Institutions. The consent order requires the Bank to complete a management study, to maintain Tier 1 capital as a percentage of total assets of at least 9% and a total risk based capital ratio of at least 12%, to develop a plan to reduce our risk position in each substandard asset in excess of $1 million, to complete board review of the adequacy of the allowance for loan losses prior to quarterly Call Report submissions, to adopt procedures which strengthen the loan review function and ensure timely and accurate grading of credit relationships, to charge-off all assets classified as loss, to develop a plan to reduce concentrations of construction and development loans to not more than 75% of total risk based capital and non-owner occupied commercial real estate loans to not more than 250% of total risk based capital, to limit asset growth to no more than 5% in any quarter or 10% annually, to not extend additional credit to any borrower classified substandard unless the board of directors adopts prior to the extension a detailed statement giving reasons why the extension is in the best interest of the bank, and to not declare or pay any dividend without the prior consent of our regulators. We are also restricted from accepting, renewing, or rolling-over brokered deposits without the prior receipt of a waiver on a case-by-case basis from our regulators.
	On September 21, 2011, we entered into a Written Agreement with the Federal Reserve Bank of St. Louis. Pursuant to the Agreement, we made formal commitments to use our financial and management resources to serve as a source of strength for the Bank and to assist the Bank in addressing weaknesses identified by the FDIC and the KDFI, to pay no dividends without prior written approval, to pay no interest or principal on subordinated debentures or trust preferred securities without prior written approval, and to submit an acceptable plan to maintain sufficient capital.
	In October 2012, the Bank entered into a new Consent Order with the FDIC and KDFI again agreeing to maintain a minimum Tier 1 leverage ratio of 9% and a minimum total risk based capital ratio of 12%. The Bank cannot be considered well-capitalized while under the Consent Order. The Bank also agreed that if it should be unable to reach the required capital levels, and if directed in writing by the FDIC, then the Bank would within 30 days develop, adopt and implement a written plan to sell or merge itself into another federally insured financial institution or otherwise immediately obtain a sufficient capital investment into the Bank to fully meet the capital requirements. We have not been directed by the FDIC to implement such a plan.
	The new Consent Order also requires the Bank to continue to adhere to the plans implemented in response to the June 2011 Consent Order, and includes the substantive provisions of the June 2011 Consent Order. As of March 31, 2014, the capital ratios required by the Consent Order were not met.
	The following table shows the ratios and amounts of Tier 1 capital and total capital to risk-adjusted assets and the leverage ratios for Porter Bancorp, Inc. and PBI Bank at the dates indicated (dollars in thousands):

		Amount		Ratio			Amount		Ratio
	Total capital to risk-weighted assets	$	83,033		11.5	%	$	86,631		12	%
	Tier I capital to average assets		68,182		6.36			96,481		9
	At March 31, 2014, PBI Bank’s Tier 1 leverage ratio was 6.36%, and its total risk-based capital ratio was 11.50%, both of which are below the minimum capital ratios required by the Consent Order. Bank regulatory agencies can exercise discretion when an institution does not meet the terms of a Consent Order. Based on individual circumstances, the agencies may issue mandatory directives, impose monetary penalties, initiate changes in management, or take more serious adverse actions.
	Kentucky banking laws limit the amount of dividends that may be paid to a holding company by its subsidiary banks without prior approval. These laws limit the amount of dividends that may be paid in any calendar year to current year’s net income, as defined in the laws, combined with the retained net income of the preceding two years, less any dividends declared during those periods. PBI Bank has agreed with its primary regulators to obtain their written consent prior to declaring or paying any future dividends. As a practical matter, PBI Bank cannot pay dividends to Porter Bancorp for the foreseeable future.

Contingencies	'
	Note 13 – Contingencies
	In the normal course of operations, we are defendants in various legal proceedings. Litigation is subject to inherent uncertainties and unfavorable rulings could occur. We record contingent liabilities resulting from claims against us when a loss is assessed to be probable and the amount of the loss is reasonably estimable. Assessing probability of loss and estimating probable losses requires analysis of multiple factors, including in some cases judgments about the potential actions of third party claimants and courts. Recorded contingent liabilities are based on the best information available and actual losses in any future period are inherently uncertain. Currently, we have accrued approximately $1.8 million related to ongoing litigation matters for which we believe liability is probable and reasonably estimable. Accruals are not made in cases where liability is not probable or the amount cannot be reasonably estimated. We provide disclosure of matters where we believe liability is reasonably possible and which may be material to our consolidated financial statements.
	Signature Point Litigation. On June 18, 2010, three real estate development companies filed suit in Kentucky state court against PBI Bank and Managed Assets of Kentucky (“MAKY”). Signature Point Condominiums LLC, et al. v. PBI Bank, et al., Jefferson Circuit Court, Case No 10-CI-04295. On July 16, 2013, a jury in Louisville, Kentucky returned a verdict against PBI Bank, awarding the plaintiffs compensatory damages of $1,515,000 and punitive damages of $5,500,000. The case arose from a settlement in which PBI Bank agreed to release the plaintiffs and guarantors from obligations of more than $26 million related to a real estate project in Louisville. The plaintiffs were granted a right of first refusal to repurchase a tract of land within the project. In exchange, the plaintiffs conveyed the real estate securing the loans to PBI Bank. After plaintiffs declined to exercise their right of first refusal, PBI Bank sold the tract to the third party. Plaintiffs alleged the Bank had knowledge of the third party offer before the conveyance of the land by the Plaintiffs to the Bank. Plaintiffs asserted claims of fraud, breach of fiduciary duty, breach of the duty of good faith and fair dealing, tortious interference with prospective business advantage and conspiracy to commit fraud, negligence, and conspiracy against PBI Bank.
	After conferring with its legal advisors, PBI Bank believes the findings and damages are excessive and contrary to law, and that it has meritorious grounds on which it is moving forward to appeal. We will continue to defend this matter vigorously. Although we have made provisions in our condensed consolidated financial statements for this self-insured matter, the amount of our legal accrual is less than the original amount of the damages awarded, plus accrued interest. The ultimate outcome of this matter could have a material adverse effect on our financial condition, results of operations or cash flows.
	SBAV LP Litigation. On December 17, 2012, SBAV LP filed a lawsuit against Porter Bancorp, PBI Bank, J. Chester Porter and Maria L. Bouvette in New York state court. The proceeding was removed to New York federal district court on January 16, 2013. On July 10, 2013, the New York federal district court granted the defendants’ motion to transfer the case to federal district court in Kentucky. SBAV LP v. Porter Bancorp, et. al., Civ. Action 3:13-CV-710 (W.D.KY). The complaint alleges violation of the Kentucky Securities Act, negligent misrepresentation and, against defendants Porter Bancorp and Bouvette, breach of contract. The plaintiff seeks damages in an amount in excess of $4,500,000, or the difference between the $5,000,016 purchase price and the value of the securities when sold by the plaintiff, plus interest at the applicable statutory rate, costs and reasonable attorneys’ fees. On September 13, 2013, defendants filed a motion to dismiss all claims in the complaint for pleading failures and for failure to state a claim upon which relief may be granted. On March 25, 2014, the judge ruled that SBAV had failed to state a claim against PBI Bank and dismissed PBI Bank from the case. The claims against Porter Bancorp, Chester Porter and Maria Bouvette remain and will proceed to discovery. On April 21, 2014, Porter Bancorp filed a third-party complaint for contribution against SBAV’s investment adviser, the Clinton Group, Inc., alleging that, to the extent the Court finds SBAV to have suffered a recoverable loss, the Clinton Group’s failure to exercise due care and negligence in conducting due diligence contributed to that loss. We dispute the material factual allegations made in SBAV’s complaint and intend to defend against SBAV’s claims vigorously.
	Thomas E. Perez, Secretary of the United States Department of Labor (DOL) v. PBI Bank, Inc. On December 26, 2013, the United States Department of Labor (“DOL”) filed a lawsuit against PBI Bank in U.S. District Court for the Northern District of Indiana. Thomas E. Perez, Secretary of the United States Department of Labor v. PBI Bank, Inc. (Civ. Action 3:13-CV-1400-PPS). The complaint alleges that in 2007 PBI Bank, in the capacity of trustee for the Miller’s Health System’s Inc. Employee Stock Ownership Plan, authorized the alleged imprudent and disloyal purchase of the stock of Miller’s Health Systems, Inc. (“Miller’s Health”) for $40 million, a price allegedly far in excess of the stock’s fair market value. The suit also alleges, among other things, that PBI Bank approved 100% seller financing for the transaction at an excessive rate of interest. On March 31, 2014, PBI Bank filed its answer, disputing the material factual allegations of the complaint. On April 10, 2014, PBI Bank filed a third-party complaint against Miller’s Health seeking to enforce its indemnity rights, as well as third party claims for contribution against named directors and officers of Miller’s Health. Based in Warsaw, Indiana, Miller’s Health managed 31 long-term care facilities and 10 assisted living facilities at the time of the 2007 acquisition. Miller’s Health also provides physical and occupational therapy and speech-language pathology to residents in its facilities. We dispute the material factual allegations made in the complaint and intend to defend against DOL’s claims vigorously.
