NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

NOTE 1 – BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned affiliates (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The allowance for loan losses, valuation of purchased loans, valuation and impairment of securities, goodwill and intangibles, derivative financial instruments, and income taxes are particularly subject to change. In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of Old National as of June 30, 2013 and 2012, and December 31, 2012, and the results of its operations for the three and six months ended June 30, 2013 and 2012. Interim results do not necessarily represent annual results. These financial statements should be read in conjunction with Old National’s Annual Report for the year ended December 31, 2012.

All significant intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform with the 2013 presentation. Such reclassifications had no effect on net income or shareholders’ equity.

NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS

FASB ASC 805 – In October 2012, the FASB issued an update (ASU No. 2012-06, Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution) impacting FASB ASC 805, Business Combinations. This update specifies that when an entity recognizes an indemnification asset as a result of a government-assisted acquisition of a financial institution and subsequently a change in the cash flows expected to be collected on the indemnification asset occurs, the entity should subsequently account for the change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. Any amortization of changes in value should be limited to the contractual term of the indemnification agreement (the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets). This update became effective for interim and annual periods beginning on or after December 15, 2012, and is consistent with the Company’s accounting treatment of changes in expected cash flows and the indemnification asset and did not have a material impact on the consolidated financial statements.

FASB ASC 220 – In February 2013, the FASB issued an update (ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income) impacting FASB ASC 220, Comprehensive Income. This update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income. An entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about these amounts. This update became effective for the Company for interim and annual periods beginning after December 15, 2012 and did not have a material impact on the consolidated financial statements.

FASB ASC 405 – In February 2013, the FASB issued an update (ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date) impacting FASB ASC 405, Liabilities. This update requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. This update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. This update becomes effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements, but it is not expected to have a material impact.

FASB ASC 405 – In July 2013, the FASB issued an update (ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes) impacting FASB ASC 815, Derivatives and Hedging. This update permits the Fed Funds Effective Swap Rate (Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes in addition to interest rates on direct Treasury obligations of the U.S. government and the London Interbank Offered Rate. This will provide a more comprehensive spectrum of interest rate resets to utilize as the designated benchmark interest rate risk component under the hedge accounting guidance. The amendments in this update are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements, but it is not expected to have a material impact.

NOTE 3 – ACQUISITION AND DIVESTITURE ACTIVITY

Indiana Community Bancorp

On September 15, 2012, Old National acquired 100% of Indiana Community Bancorp (“IBT”) in an all stock transaction. IBT was headquartered in Columbus, Indiana and had 17 full-service banking centers serving the South Central Indiana area. The acquisition increased Old National’s position as the third largest branch network in Indiana and allowed Old National to enter into the vibrant, growing region of south central Indiana in a rapid and cost effective manner. We also believe there are opportunities to enhance income and improve efficiencies. Pursuant to the merger agreement, the shareholders of IBT received approximately 6.6 million shares of Old National Bancorp stock valued at approximately $88.5 million.

Under the acquisition method of accounting, the total estimated purchase price is allocated to IBT’s net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on management’s preliminary valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on assumptions that are subject to change, the purchase price for the IBT acquisition is allocated as follows (in thousands):

Cash and cash equivalents	$	78,540
Investment securities—available for sale		147,710
Federal Home Loan Bank stock, at cost		7,092
Loans		497,434
Premises and equipment		13,345
Accrued interest receivable		2,165
Other real estate owned		6,111
Company-owned life insurance		15,833
Other assets		49,655
Deposits		(784,589	)
Other borrowings		(15,464	)
Accrued expenses and other liabilities		(18,564	)
Net tangible assets acquired		(732	)
Definite-lived intangible assets acquired		3,024
Goodwill		86,205
Purchase price	$	88,497

Prior to the end of the one year measurement period for finalizing the purchase price allocation, if information becomes available which would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocation retrospectively. During the fourth quarter of 2012, adjustments were made in the purchase price allocation that affected the amounts allocated to loans, other real estate owned, other assets, accrued expenses and other liabilities and goodwill. During the second quarter of 2013, adjustments were made in the purchase price allocation that affected the amounts allocated to premises and equipment, other assets, accrued expenses and other liabilities and goodwill.

9

Of the total purchase price, $0.7 million has been allocated to net tangible liabilities acquired and $3.0 million has been allocated to definite-lived intangible assets acquired. The remaining purchase price has been allocated to goodwill. The goodwill will not be deductible for tax purposes and is included in the “Community Banking” and “Other” segments, as described in Note 20 of these consolidated financial statement footnotes.

The components of the estimated fair value of the acquired identifiable intangible assets are in the table below. These intangible assets will be amortized on an accelerated basis over their estimated lives and are included in the “Community Banking” and “Other” segments, as described in Note 20 of these consolidated financial statement footnotes.

	Estimated
	Fair Value		Estimated
	(in millions)		Useful Lives (Years)
Core deposit intangible	$	1.3		7
Trust customer relationship intangible	$	1.7		12

Divestiture

On August 16, 2012, Old National announced plans to sell the deposits of nine banking centers located in southern Illinois and western Kentucky. As such, these deposits were considered held for sale as of December 31, 2012. The deposits totaled approximately $150.0 million at December 31, 2012. Old National also announced plans to consolidate 19 banking centers into existing branch locations. The consolidations occurred during the fourth quarter of 2012 and the sales closed during the first quarter of 2013. Deposits at the time of sale were approximately $150.1 million and the Company received a deposit premium of $2.2 million on the sales during the first quarter of 2013.

Branch Acquisition

On January 9, 2013 Old National announced that it had entered into a purchase and assumption agreement to acquire 24 bank branches of Bank of America. Four of the branches are located in northern Indiana and 20 branches are located in southwest Michigan. Deposit and loan balances to be included in the transaction were approximately $575.0 million and $5.0 million, respectively, as of July 9, 2013. The Company paid a deposit premium of 2.94%. The acquisition has doubled Old National’s presence in the South Bend/Elkhart area and provided a logical market extension into southwest Michigan. The transaction closed on July 12, 2013.

(1) No shares of restricted stock awards or restricted stock units were excluded in the computation of net income per diluted share for the second quarter ended June 30, 2013 and 2012, respectively, because the effect would be antidilutive. 0 and 1 shares of restricted stock and restricted stock units were excluded in the computation of net income per diluted share for the six months ended June 30, 2013 and 2012, respectively, because the effect would be antidilutive.

(2) Options to purchase 1,294 shares and 3,113 shares outstanding at June 30, 2013 and 2012, respectively, were excluded in the computation of net income per diluted share for the second quarter ended June 30, 2013 and 2012, respectively, because the exercise price of these options was greater than the average market price of the common shares and, therefore, the effect would be antidilutive. Options to purchase 1,202 and 3,106 shares outstanding at June 30, 2013 and 2012, respectively, were excluded in the computation of net income per diluted share for the six months ended June 30, 2013 and 2012, respectively, because the exercise price of these options was greater than the average market price of the common shares and, therefore, the effect would be antidilutive.

All of the mortgage-backed securities in the investment portfolio are residential mortgage-backed securities. The amortized cost and fair value of the investment securities portfolio are shown by expected maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Weighted average yield is based on amortized cost.

Proceeds from sales and calls of securities available for sale were $307.4 million and $197.3 million for the six months ended June 30, 2013 and 2012, respectively. Gains of $2.5 million and $7.6 million were realized on these sales during 2013 and 2012, respectively. Also included in net securities gains for the first six months of 2013 is $204 thousand of gains associated with the trading securities and $195 thousand of gains from mutual funds. There were no other-than-temporary impairment charges related to credit loss in the first six months of 2013. Impacting earnings in the first six months of 2012 was $45 thousand of gains associated with the trading securities and other-than-temporary impairment charges related to credit loss on five non-agency mortgage-backed securities and one trust preferred security in the amount of $876 thousand.

Trading securities, which consist of mutual funds held in a trust associated with deferred compensation plans for former Monroe Bancorp directors and executives, are recorded at fair value and totaled $3.3 million at June 30, 2013 and $3.1 million at December 31, 2012.

During the third quarter of 2012, approximately $46.1 million of state and political subdivision securities were transferred from the held-to-maturity portfolio to the available-for-sale portfolio due to changes in circumstances associated with the Office of Management and Budget’s report outlining sequestration and the implications for taxable Build America Bonds. Specifically, the release indicated that if U.S. policymakers failed to address the fiscal cliff and take legislative action, a series of key fiscal measures would occur in January. One of these measures that involves automatic spending cuts (or “sequestration”) mandated by the Budget Control Act had, among other things, implications for taxable “Build America Bonds” (“BABs”). The OMB included in its report that 7.6%, or $322 million, of subsidy payments authorized for issuers of BABs would be reduced in 2013. This cut could in turn trigger an “Extraordinary Redemption Provision” within the BAB structure allowing the issuer to potentially call some bonds at par. This par call could generate a large loss for buyers of BABs if they paid a premium for these securities at purchase.

19

Old National owns a significant number of premium BABs, largely classified as held-to-maturity securities, that would generate a loss if called at par. In response to this event and consistent with FASB ASC 320-10-25-6, Old National moved certain BABs from held-to-maturity to available-for-sale based on the following criteria:

1) BABS that were purchased at a premium;

2) BABS with a par value of $1.0 million or more (BABS with a par value below $1.0 million remained in held-to-maturity as, in management’s opinion, they would not have a material negative impact on earnings if called at par).

Once these BABS were reclassified, Old National reviewed each holding for potential sale in order to limit any negative earnings impact.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under FASB ASC 320 (SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities). However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in FASB ASC 325-10 (EITF Issue No. 99-20, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets).

In determining OTTI under the FASB ASC 320 (SFAS No. 115) model, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. The second segment of the portfolio uses the OTTI guidance provided by FASB ASC 325-10 (EITF 99-20) that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the FASB ASC 325-10 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.

When other-than-temporary-impairment occurs under either model, the amount of the other-than-temporary-impairment recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary-impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. Otherwise, the other-than-temporary-impairment shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total other-than-temporary-impairment related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total other-than-temporary-impairment related to other factors shall be recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the other-than-temporary-impairment recognized in earnings shall become the new amortized cost basis of the investment.

There was no other-than-temporary-impairment recorded in the first six months of 2013. In the first half of 2012, $0.9 million of other-than-temporary-impairment was recorded.

As of June 30, 2013, Old National’s securities portfolio consisted of 1,328 securities, 374 of which were in an unrealized loss position. Unrealized losses related to Old National’s holdings of pooled trust preferred securities have remained for the longest continuous period of time and are discussed below.

Pooled Trust Preferred Securities

At June 30, 2013, the Company’s securities portfolio contained five pooled trust preferred securities with a fair value of $9.2 million and unrealized losses of $13.9 million. Three of the pooled trust preferred securities in our portfolio fall within the scope of FASB ASC 325-10 (EITF 99-20) and have a fair value of $3.2 million with unrealized losses of $5.6 million at June 30, 2013. These securities were rated A2 and A3 at inception, but at June 30, 2013, one security was rated CC, one security was rated C and one security D. The issuers in these securities are primarily banks, but some of the pools do include a limited number of insurance companies. The Company uses the OTTI evaluation model to compare the present value of expected cash flows to the previous estimate to determine whether an adverse change in cash flows has occurred during the quarter. The OTTI model considers the structure and term of the collateralized debt obligation (“CDO”) and the financial condition of the underlying issuers. Specifically, the model details interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes. The current estimate of expected cash flows is based on the most recent trustee reports and any other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred securities. Assumptions used in the model include expected future default rates and prepayments. We assume no recoveries on defaults and a limited number of recoveries on current or projected interest payment deferrals. In addition, we use the model to “stress” each CDO, or make assumptions more severe than expected activity, to determine the degree to which assumptions could deteriorate before the CDO could no longer fully support repayment of Old National’s note class. For the six months ended June 30, 2013, our model indicated no other-than-temporary-impairment losses on these securities. During the first quarter of 2013 one of these securities was sold. The Company recorded a gain of $224 thousand associated with this sale. At June 30, 2013, the Company has no intent to sell any of these securities that are in an unrealized loss position.

Two of our pooled trust preferred securities with a fair value of $6.0 million and unrealized losses of $8.3 million at June 30, 2013 are not subject to FASB ASC 325-10. These securities are evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. Our analysis indicated no other-than-temporary-impairment on these securities.

For the six months ended June 30, 2012, the six securities subject to FASB ASC 325-10 accounted for $7.1 million of the unrealized losses in the pooled trust preferred securities category. For the six months ended June 30, 2012, our model indicated other-than-temporary-impairment losses on one security of $161 thousand, all of which was recorded as a credit loss in earnings. At June 30, 2012, the fair value of this security was $475 thousand and it was classified as available for sale.

Two of our pooled trust preferred securities with a fair value of $4.6 million and unrealized losses of $9.7 million at June 30, 2012 were not subject to FASB ASC 325-10. These securities were evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. Our analysis indicated no other-than-temporary-impairment on these securities.

The table below summarizes the relevant characteristics of our five pooled trust preferred securities as well as five single issuer trust preferred securities which are included with other securities in Note 6 to the consolidated financial statements. Each of the pooled trust preferred securities support a more senior tranche of security holders except for the MM Community Funding II security which, due to payoffs, Old National is now in the most senior class.

As depicted in the table below, all five securities have experienced credit defaults. However, two of these securities have excess subordination and are not other-than-temporarily-impaired as a result of their class hierarchy which provides more loss protection.

NOTE 7 – LOANS HELD FOR SALE

Residential loans that Old National has committed to sell are recorded at fair value in accordance with FASB ASC 825-10 (SFAS No. 159 – The Fair Value Option for Financial Assets and Financial Liabilities). At June 30, 2013 and December 31, 2012, Old National had residential loans held for sale of $13.6 million and $12.6 million, respectively.

At June 30, 2013, Old National had taxable finance leases held for sale of $11.6 million. These leases were transferred from the commercial loan category at fair value and a loss of $0.2 million was recognized. The portfolio of leases held for sale has an average maturity of 2.7 years and interest rates ranging from 3.57% to 10.22%. The leases held for sale are to a variety of borrowers, with various types of equipment securing the leases, and all of the leases are current. Old National does not intend to sell its nontaxable finance leases.

During the first six months of 2013, commercial and commercial real estate loans held for investment of $3.6 million, including $0.4 million of purchased impaired loans, were reclassified to loans held for sale at the lower of cost or fair value and sold for $4.8 million, resulting in a charge-off of $0.2 million, recoveries of $0.4 million and other income of $1.0 million. At June 30, 2013, there were no loans held for sale under this arrangement.

During the first six months of 2012, commercial and commercial real estate loans held for investment of $1.6 million, including $1.5 million of purchased impaired loans, were reclassified to loans held for sale at the lower of cost or fair value and sold for $2.2 million, resulting in a charge-off of $0.1 million and a recovery of $0.7 million. At June 30, 2012, there were no loans held for sale under this arrangement.

NOTE 8 – LOANS AND ALLOWANCE FOR CREDIT LOSSES

Old National’s finance receivables consist primarily of loans made to consumers and commercial clients in various industries including manufacturing, agribusiness, transportation, mining, wholesaling and retailing. Most of Old National’s lending activity occurs within the Company’s principal geographic markets of Indiana, Illinois and Kentucky. Old National has no concentration of commercial loans in any single industry exceeding 10% of its portfolio.

The composition of loans by lending classification was as follows:

	June 30,			December 31,
(dollars in thousands)	2013			2012
Commercial (1)	$	1,397,882		$	1,336,820

Allowance for loan losses—covered loans		(5,428	)		(5,716	)
Net loans	$	5,126,904		$	5,141,831

(1) Includes direct finance leases of $34.8 million at June 30, 2013 and $57.7 million at December 31, 2012.

Portfolio loans, or loans Old National intends to hold for investment purposes, are carried at the principal balance outstanding, net of earned interest, purchase premiums or discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the principal balances of loans outstanding.

The risk characteristics of each loan portfolio segment are as follows:

Commercial

Commercial loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.

Commercial real estate

These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing Old National’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, Old National avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans.

24

Included with commercial real estate are construction loans, which are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based on estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from Old National until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.

Residential

With respect to residential loans that are secured by 1-4 family residences and are generally owner occupied, Old National typically establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in residential property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Consumer

Home equity loans are typically secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in residential property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Covered Loans

On July 29, 2011, Old National acquired the banking operations of Integra Bank N.A. (“Integra”) in an FDIC assisted transaction. As part of the purchase and assumption agreement, the Company and the FDIC entered into loss sharing agreements (each, a “loss sharing agreement” and collectively, the “loss sharing agreements”), whereby the FDIC will cover a substantial portion of any future losses on loans (and related unfunded commitments), other real estate owned (“OREO”) and up to 90 days of certain accrued interest on loans. The acquired loans and OREO subject to the loss sharing agreements are referred to collectively as “covered assets.” Under the terms of the loss sharing agreements, the FDIC will reimburse Old National for 80% of losses up to $275.0 million, losses in excess of $275.0 million up to $467.2 million at 0% reimbursement, and 80% of losses in excess of $467.2 million. As of June 30, 2013, we do not expect losses to exceed $275.0 million. Old National will reimburse the FDIC for its share of recoveries with respect to losses for which the FDIC has reimbursed the Bank under the loss sharing agreements. The loss sharing provisions of the agreements for commercial and single family residential mortgage loans are in effect for five and ten years, respectively, from the July 29, 2011 acquisition date and the loss recovery provisions for such loans are in effect for eight years and ten years, respectively, from the acquisition date.

Allowance for loan losses

The allowance for loan losses is maintained at a level believed adequate by management to absorb probable losses incurred in the loan portfolio. Management’s evaluation of the adequacy of the allowance is an estimate based on reviews of individual loans, pools of homogeneous loans, historical loss experience, and assessments of the impact of current economic conditions on the portfolio.

25

The allowance is increased through a provision charged to operating expense. Loans deemed to be uncollectible are charged to the allowance. Recoveries of loans previously charged-off are added to the allowance.

No allowance was brought forward on any of the acquired loans as any credit deterioration evident in the loans was included in the determination of the fair value of the loans at the acquisition date. Purchased credit impaired (“PCI”) loans are not considered impaired until after the point at which there has been a degradation of cash flows below our expected cash flows at acquisition. Impairment on PCI loans would be recognized in the current period as provision expense.

Credit Quality

Old National’s management monitors the credit quality of its financing receivables in an on-going manner. Internally, management assigns a credit quality grade to each non-homogeneous commercial and commercial real estate loan in the portfolio. The primary determinants of the credit quality grade are based upon the reliability of the primary source of repayment and the past, present, and projected financial condition of the borrower. The credit quality rating also reflects current economic and industry conditions. Major factors used in determining the grade can vary based on the nature of the loan, but commonly include factors such as debt service coverage, internal cash flow, liquidity, leverage, operating performance, debt burden, FICO scores, occupancy, interest rate sensitivity, and expense burden. Old National uses the following definitions for risk ratings:

Criticized. Special mention loans that have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Classified – Substandard. Loans classified as substandard are inadequately protected by the current net 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 the institution will sustain some loss if the deficiencies are not corrected.

Classified – Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Pass rated loans are those loans that are other than criticized, classified – substandard or classified – doubtful.

As of June 30, 2013 and December 31, 2012, the risk category of loans, excluding covered loans, by class of loans is as follows:

Old National considers the performance of the loan portfolio and its impact on the allowance for loan losses. For residential and consumer loan classes, Old National also evaluates credit quality based on the aging status of the loan and by payment activity. The following table presents the recorded investment in residential and consumer loans based on payment activity as of June 30, 2013 and December 31, 2012, excluding covered loans:

Impaired Loans

Large commercial credits are subject to individual evaluation for impairment. Retail credits and other small balance credits that are part of a homogeneous group are not tested for individual impairment unless they are modified as a troubled debt restructuring. A loan is considered impaired when it is probable that contractual interest and principal payments will not be collected either for the amounts or by the dates as scheduled in the loan agreement. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net, at the present value of estimated cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Old National’s policy, for all but purchased credit impaired loans, is to recognize interest income on impaired loans unless the loan is placed on nonaccrual status. For the six months ended June 30, 2013 and 2012, the average balance of impaired loans was $76.4 million and $72.0 million, respectively, for which no interest income was recorded. No additional funds are committed to be advanced in connection with these impaired loans.

The following table shows Old National’s impaired loans, excluding covered loans, that are individually evaluated as of June 30, 2013 and December 31, 2012. Of the loans purchased during 2012 and 2011 without FDIC loss share coverage, only those that have experienced subsequent impairment since the date acquired are included in the table below.

(1) The Company does not record interest on nonaccrual loans until principal is recovered.

For all loan classes, a loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectibility of principal or interest. Interest accrued during the current year on such loans is reversed against earnings. Interest accrued in the prior year, if any, is charged to the allowance for loan losses. Cash interest received on these loans is applied to the principal balance until the principal is recovered or until the loan returns to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, remain current for six months and future payments are reasonably assured.

Covered loans accounted for under FASB ASC Topic 310-30 accrue interest, even though they may be contractually past due, as any nonpayment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or prospective yield adjustments. Similar to uncovered loans, covered loans accounted for outside FASB ASC Topic 310-30 are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful. Information for covered loans accounted for both under and outside FASB ASC Topic 310-30 is included in the table below in the row labeled covered loans.

Loan Participations

Old National has loan participations, which qualify as participating interests, with other financial institutions. At June 30, 2013, these loans totaled $225.7 million, of which $140.6 million had been sold to other financial institutions and $85.1 million was retained by Old National. The loan participations convey proportionate ownership rights with equal priority to each participating interest holder, involve no recourse (other than ordinary representations and warranties) to, or subordination by, any participating interest holder, all cash flows are divided among the participating interest holders in proportion to each holder’s share of ownership and no holder has the right to pledge the entire financial asset unless all participating interest holders agree.

Troubled Debt Restructurings

Old National may choose to restructure the contractual terms of certain loans. The decision to restructure a loan, versus aggressively enforcing the collection of the loan, may benefit Old National by increasing the ultimate probability of collection.

Any loans that are modified are reviewed by Old National to identify if a troubled debt restructuring (“TDR”) has occurred, which is when for economic or legal reasons related to a borrower’s financial difficulties, the Bank grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. During the six months ended June 30, 2013, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date at a stated rate of interest lower than the current market rate of new debt with similar risk, or a permanent reduction of the recorded investment of the loan.

33

Loans modified in a troubled debt restructuring are typically placed on nonaccrual status until the Company determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrate a period of performance according to the restructured terms for six months.

If the Company is unable to resolve a nonperforming loan issue, the credit will be charged off when it is apparent there will be a loss. For large commercial type loans, each relationship is individually analyzed for evidence of apparent loss based on quantitative benchmarks or subjectively based upon certain events or particular circumstances. It is Old National’s policy to charge off small commercial loans scored through our small business credit center with contractual balances under $250,000 that have been placed on nonaccrual status or became ninety days or more delinquent, without regard to the collateral position. For residential and consumer loans, a charge off is recorded at the time foreclosure is initiated or when the loan becomes 120 to 180 days past due, whichever is earlier.

For commercial troubled debt restructurings, an allocated reserve is established within the allowance for loan losses for the difference between the carrying value of the loan and its computed fair value. To determine the fair value of the loan, one of the following methods is selected: (1) the present value of expected cash flows discounted at the loans original effective interest rate, (2) the loan’s observable market price, or (3) the fair value of the collateral value, if the loan is collateral dependent. The allocated reserve is established as the difference between the carrying value of the loan and the collectable value. If there are significant changes in the amount or timing of the loan’s expected future cash flows, impairment is recalculated and the valuation allowance is adjusted accordingly.

For consumer and residential troubled debt restructurings, an additional amount is added to the loan loss reserve that represents the difference in the present value of the cash flows between the original terms and the new terms of the modified loan, using the original effective interest rate of the loan as a discount rate.

At June 30, 2013, our troubled debt restructurings consisted of $11.4 million of commercial loans, $19.2 million of commercial real estate loans, $0.8 million of consumer loans and $0.7 million of residential loans, totaling $32.1 million. Approximately $21.5 million of the troubled debt restructuring at June 30, 2013 were included with nonaccrual loans. At December 31, 2012, our troubled debt restructurings consisted of $12.7 million of commercial loans, $18.4 million of commercial real estate loans, $0.5 million of consumer loans and $0.5 million of residential loans, totaling $32.1 million. Approximately $22.1 million of the troubled debt restructuring at December 31, 2012 were included with nonaccrual loans.

As of June 30, 2013 and December 31, 2012, Old National has allocated $3.9 million and $4.5 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings, respectively. Old National has not committed to lend any additional amounts as of June 30, 2013 and December 31, 2012, respectively, to customers with outstanding loans that are classified as troubled debt restructurings.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

The terms of certain other loans were modified during the six months ended June 30, 2013 that did not meet the definition of a troubled debt restructuring. It is our process to review all classified and criticized loans that, during the period, have been renewed, have entered into a forbearance agreement, have gone from principal and interest to interest only, or have had the maturity date extended. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on its debt in the foreseeable future without the modification. The evaluation is performed under the Company’s internal underwriting policy. We also evaluate whether a concession has been granted or if we were adequately compensated through a market interest rate, additional collateral or a bona fide guarantee. We also consider whether the modification was insignificant relative to the other terms of the agreement or if the delay in a payment was 90 days or less.

35

Purchased credit impaired (“PCI”) loans are not considered impaired until after the point at which there has been a degradation of cash flows below our expected cash flows at acquisition. If a PCI loan is subsequently modified, and meets the definition of a TDR, it will be removed from PCI accounting and accounted for as a TDR only if the PCI loan was being accounted for individually. If the purchased credit impaired loan is being accounted for as part of a pool, it will not be removed from the pool. As of June 30, 2013, it has not been necessary to remove any loans from PCI accounting.

In general, once a modified loan is considered a TDR, the loan will always be considered a TDR, and therefore impaired, until it is paid in full, otherwise settled, sold or charged off. However, our policy also permits for loans to be removed from troubled debt restructuring status in the years following the restructuring if the following two conditions are met: (1) The restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk, and (2) the loan is not impaired based on the terms specified by the restructuring agreement.

Purchased Impaired Loans (non-covered loans)

Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date with no carryover of the related allowance for loan and lease losses. In determining the estimated fair value of purchased loans, management considers a number of factors including the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, net present value of cash flows expected to be received, among others. Purchased loans are accounted for in accordance with guidance for certain loans acquired in a transfer (ASC 310-30), when the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield, which would have a positive impact on interest income.

36

Old National has purchased loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. Of these acquired credit impaired loans, $4.0 million in carrying balances did not meet the criteria to be accounted for under the guidance of ASC 310-30 as they were revolving lines of credit, thus these lines have not been included in the following table. For these noncovered loans that meet the criteria of ASC 310-30 treatment, the carrying amount is as follows:

	June 30,		December 31,
(dollars in thousands)	2013		2012
Commercial	$	440	$	7,859
Commercial real estate		40,652		52,981
Consumer		16,408		22,432
Residential		120		123
Carrying amount	$	57,620	$	83,395
Carrying amount, net of allowance	$	54,132	$	79,120
Allowance for loan losses	$	3,488	$	4,275

The outstanding balance of noncovered loans accounted for under ASC 310-30, including contractual principal, interest, fees and penalties, was $146.3 million and $179.5 million as of June 30, 2013 and December 31, 2012, respectively.

The accretable difference on purchased loans acquired in a business combination is the difference between the expected cash flows and the net present value of expected cash flows with such difference accreted into earnings using the effective yield method over the term of the loans. Accretion of $8.9 million has been recorded as loan interest income through the six months ended June 30, 2013. Accretion of $6.0 million was recorded as loan interest income through the six months ended June 30, 2012. Improvement in cash flow expectations has resulted in a reclassification from nonaccretable difference to accretable yield.

Accretable yield of noncovered loans, or income expected to be collected, is as follows:

				Integra
(dollars in thousands)	Monroe			Noncovered			IBT			Total

Included in Old National’s allowance for loan losses is $3.5 million related to the purchased loans disclosed above for the first six months of 2013. Included in Old National’s allowance for loan losses was $4.3 million related to the purchased loans in 2012. An immaterial amount of allowances for loan losses were reversed during 2013 and 2012 related to these loans.

Purchased loans, as of the date of acquisition, for which it was probable that all contractually required payments would not be collected are as follows:

	Monroe			Integra
(dollars in thousands)	Bancorp			Bank (1)			IBT
Contractually required payments	$	94,714		$	921,856		$	118,535

Fair value of acquired loans at acquisition	$	42,586		$	596,943		$	53,425

(1) Includes covered and noncovered.

Income is not recognized on certain purchased loans if Old National cannot reasonably estimate cash flows to be collected. Old National had no purchased loans for which it could not reasonably estimate cash flows to be collected.

NOTE 9 – COVERED LOANS

Covered loans represent loans acquired from the FDIC that are subject to loss share agreements. The carrying amount of covered loans was $288.6 million at June 30, 2013. The composition of covered loans by lending classification was as follows:

	At June 30, 2013

Covered loans, net	$	174,979		$	108,170	$	283,149

(1) Includes loans with revolving privileges which are scoped out of FASB ASC 310-30 and certain loans which Old National elected to treat under the cost recovery method of accounting.

Loans were recorded at fair value in accordance with FASB ASC 805, Business Combinations. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. Loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in FASB ASC 820, exclusive of the loss share agreements with the Federal Deposit Insurance Corporation (“FDIC”). The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows.

The outstanding balance of covered loans accounted for under ASC 310-30, including contractual principal, interest, fees and penalties, was $446.3 million and $529.2 million as of June 30, 2013 and December 31, 2012, respectively.

Balance at June 30, 2012	$	610,091		$	(155,171	)	$	(100,303	)	$	354,617

(1) The balance of contractual cash flows includes future contractual interest and is net of amounts charged off and interest collected on nonaccrual loans.

Over the life of the acquired loans, the Company continues to estimate cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics which were treated in the aggregate when applying various valuation techniques. The Company evaluates at each balance sheet date whether the present value of its loans determined using the effective interest rates has decreased and if so, recognizes a provision for loan losses. For any increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life. Eighty percent of the prospective yield adjustments are offset as Old National will recognize a corresponding decrease in cash flows expected from the indemnification asset prospectively in a similar manner. The indemnification asset is adjusted over the shorter of the life of the underlying investment or the indemnification agreement.

Accretable yield, or income expected to be collected on the covered loans accounted for under ASC 310-30, is as follows:

(dollars in thousands)	2013			2012
Balance at January 1,	$	85,779		$	92,053
New loans purchased		—			—
Accretion of income		(19,174	)		(26,102	)

Disposals/other adjustments		1,663			(1,326	)
Balance at June 30,	$	77,141		$	100,303

39

At June 30, 2013, the $100.4 million loss sharing asset is comprised of an $89.6 million FDIC indemnification asset and a $10.8 million FDIC loss share receivable. The loss share receivable represents actual incurred losses where reimbursement has not yet been received from the FDIC. The indemnification asset represents future cash flows the Company expects to collect from the FDIC under the loss sharing agreements and the amount related to the estimated improvements in cash flow expectations that are being amortized over the same period for which those improved cash flows are being accreted into income. At June 30, 2013, $63.8 million of the FDIC indemnification asset is related to expected indemnification payments and $25.8 million is expected to be amortized and reported in noninterest income as an offset to future accreted interest income.

For covered loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the quarterly re-measurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. As a result of this impairment, the indemnification asset is increased to reflect anticipated future cash flows to be received from the FDIC. Consistent with the loss sharing agreements between the Company and the FDIC, the amount of the increase to the indemnification asset is measured at 80% of the resulting impairment.

Alternatively, when the quarterly re-measurement results in an increase in expected future cash flows due to a decrease in expected credit losses, the nonaccretable difference decreases and the effective yield of the related loan portfolio is increased. As a result of the improved expected cash flows, the indemnification asset would be reduced first by the amount of any impairment previously recorded and, second, by increased amortization over the remaining life of the related loss sharing agreements.

The following table shows a detailed analysis of the FDIC loss sharing asset for the six months ended June 30, 2013 and 2012:

Covered OREO expenses and valuation write-downs are recorded in the noninterest expense section of the consolidated statements of income. Under the loss sharing agreements, the FDIC will reimburse the Company for 80% of expenses and valuation write-downs related to covered assets up to $275.0 million, losses in excess of $275.0 million up to $467.2 million at 0%, and 80% of losses in excess of $467.2 million. As of June 30, 2013, we do not expect losses to exceed $275.0 million. The reimbursable portion of these expenses is recorded in the FDIC indemnification asset. Changes in the FDIC indemnification asset are recorded in the noninterest income section of the consolidated statements of income.

NOTE 11 – GOODWILL AND OTHER INTANGIBLE ASSETS

The following table shows the changes in the carrying amount of goodwill by segment for the six months ended June 30, 2013 and 2012:

	Community
(dollars in thousands)	Banking		Other		Total

Goodwill acquired during the period		—		—		—
Balance, June 30, 2012	$	212,412	$	40,765	$	253,177

Goodwill is reviewed annually for impairment. Old National completed its most recent annual goodwill impairment test as of August 31, 2012 and concluded that, based on current events and circumstances, it is not more likely than not that the carry value of goodwill exceeds fair value. During the second quarter of 2013, Old National recorded $0.6 million of goodwill primarily related to the final pension settlement associated with the Indiana Community Bancorp acquisition. This was allocated to the “Community Banking” segment. During the second half of 2012, Old National recorded $85.6 million of goodwill associated with the acquisition of Indiana Community Bancorp, of which $84.6 million was allocated to the “Community Banking” segment and $1.0 million to the “Other” segment.

Other intangible assets consist of core deposit intangibles and customer relationship intangibles and are being amortized primarily on an accelerated basis over their estimated useful lives, generally over a period of 5 to 15 years. During the second quarter of 2013, Old National increased customer business relationships by $0.1 million related to the purchase of an insurance book of business, which is included in the “Other” segment. During the third quarter of 2012, Old National increased core deposit intangibles by $1.3 million related to the acquisition of Indiana Community Bancorp, which is included in the “Community Banking” segment. Also during the third quarter of 2012, Old National increased customer relationship intangibles by $1.7 million associated with the trust business of Indiana Community Bancorp, which is included in the “Other” segment. During the second quarter of 2012, Old National increased customer business relationships by $0.5 million relating to the purchase of an insurance book of business, which is included in the “Other” segment.

Old National reviews other intangible assets for possible impairment whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. No impairment charges were recorded in 2013 or 2012. Total amortization expense associated with other intangible assets for the six months ended June 30 was $4.4 million in 2013 and $3.9 million in 2012. Included in expense for the first quarter of 2013 is $0.6 million related to the branch sales that occurred in the first quarter.

Estimated amortization expense for future years is as follows:

FEDERAL HOME LOAN BANK

Federal Home Loan Bank advances had weighted-average rates of 0.62% and 3.07% at June 30, 2013, and December 31, 2012, respectively. These borrowings are collateralized by investment securities and residential real estate loans up to 145% of outstanding debt.

In the first six months of 2013, Old National has terminated $50.0 million of Federal Home Loan Bank advances, resulting in a loss on extinguishment of debt of $1.0 million. Old National also restructured $33.4 million pertaining to two FHLB advances in the first quarter of 2013, which lowered their effective interest rates from 3.27% and 3.29% to 2.04% and 2.49%, respectively.

JUNIOR SUBORDINATED DEBENTURES

Junior subordinated debentures related to trust preferred securities are classified in “other borrowings”. These securities qualify as Tier 1 capital for regulatory purposes, subject to certain limitations.

In 2007, Old National acquired St. Joseph Capital Trust II in conjunction with its acquisition of St. Joseph Capital Corporation. Old National guarantees the payment of distributions on the trust preferred securities issued by St. Joseph Capital Trust II. St. Joseph Capital Trust II issued $5.0 million in preferred securities in March 2005. The preferred securities had a cumulative annual distribution rate of 6.27% until March 2010 and now carry a variable rate of interest priced at the three-month LIBOR plus 175 basis points, payable quarterly and maturing on March 17, 2035. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by St. Joseph Capital Trust II. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities.

In 2011, Old National acquired Monroe Bancorp Capital Trust I and Monroe Bancorp Statutory Trust II in conjunction with its acquisition of Monroe Bancorp. Old National guarantees the payment of distributions on the trust preferred securities issued by Monroe Bancorp Capital Trust I and Monroe Bancorp Statutory Trust II. Monroe Bancorp Capital Trust I issued $3.0 million in preferred securities in July 2006. The preferred securities carried a fixed rate of interest of 7.15% until October 7, 2011 and thereafter a variable rate of interest priced at the three-month LIBOR plus 160 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Monroe Bancorp Capital Trust I. Monroe Bancorp Statutory Trust II issued $5.0 million in preferred securities in March 2007. The preferred securities carried a fixed rate of interest of 6.52% until June 15, 2012 and thereafter a variable rate of interest priced at the three-month LIBOR plus 160 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Monroe Bancorp Statutory Trust II. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities in whole or in part.

In 2012, Old National acquired Home Federal Statutory Trust I in conjunction with its acquisition of Indiana Community Bancorp. Old National guarantees the payment of distributions on the trust preferred securities issued by Home Federal Statutory Trust I. Home Federal Statutory Trust I issued $15.0 million in preferred securities in September 2006. The preferred securities carry a variable rate of interest priced at the three-month LIBOR plus 165 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Home Federal Statutory Trust I. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities in whole or in part.

CAPITAL LEASE OBLIGATION

On January 1, 2004, Old National entered into a long-term capital lease obligation for a branch office building in Owensboro, Kentucky, which extends for 25 years with one renewal option for 10 years. The economic substance of this lease is that Old National is financing the acquisition of the building through the lease and accordingly, the building is recorded as an asset and the lease is recorded as a liability. The fair value of the capital lease obligation was estimated using a discounted cash flow analysis based on Old National’s current incremental borrowing rate for similar types of borrowing arrangements.

44

At June 30, 2013, the future minimum lease payments under the capital lease were as follows:

(dollars in thousands)
2013 remaining	$	195
2014		410
2015		410
2016		410
2017		410
Thereafter		9,673
Total minimum lease payments		11,508

NOTE 14 – EMPLOYEE BENEFIT PLANS

RETIREMENT PLAN

Old National maintains a funded noncontributory defined benefit plan (the “Retirement Plan”) that was frozen as of December 31, 2005. Retirement benefits are based on years of service and compensation during the highest paid five years of employment. The freezing of the plan provides that future salary increases will not be considered. Old National’s policy is to contribute at least the minimum funding requirement determined by the plan’s actuary. Old National expects to contribute approximately $180 thousand to the Retirement Plan in 2013.

Old National also maintains an unfunded pension restoration plan (the “Restoration Plan”) which provides benefits for eligible employees that are in excess of the limits under Section 415 of the Internal Revenue Code of 1986, as amended, that apply to the Retirement Plan. The Restoration Plan is designed to comply with the requirements of ERISA. The entire cost of the plan, which was also frozen as of December 31, 2005, is supported by contributions from the Company.

Old National contributed $63 thousand to cover benefit payments from the Restoration Plan during the first six months of 2013. Old National expects to contribute an additional $60 thousand to cover benefit payments from the Restoration Plan during the remainder of 2013.

The net periodic benefit cost and its components were as follows for the three and six months ended June 30:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
(dollars in thousands)	2013			2012			2013			2012
Interest cost	$	435		$	493		$	870		$	986
Expected return on plan assets		(551	)		(587	)		(1,101	)		(1,173	)
Recognized actuarial loss		580			1,007			1,159			2,013
Settlement		144			—			423			—
Net periodic benefit cost	$	608		$	913		$	1,351		$	1,826

On September 15, 2012, Old National assumed Indiana Bank and Trust’s Pentegra Defined Benefit Plan for Financial Institutions. This defined benefit pension plan has been frozen since April 1, 2008. The trustees of the Financial Institutions Retirement Fund administer the Pentegra Plan, employer identification number 13-5645888 and plan number 333. The Pentegra Plan operates as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code.

45

The Pentegra Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra Plan contributions made by a contributing employer may be used to provide benefits to participants of other participating employers. There is no separate valuation of the Pentegra Plan benefits or segregation of the Pentegra Plan assets specifically for a company, because the Pentegra Plan is a multi-employer plan and separate actuarial valuations are not made with respect to each employer. The funded status of the Pentegra Plan, or the market value of plan assets divided by funding target, as of July 1, 2012 and 2011 was 101.2% and 84.4%, respectively.

During the second quarter of 2013, Old National withdrew from the plan, contributing $14.0 million to satisfy the final termination liability. Funding the termination liability had no impact on earnings as it was considered in the fair value of Indiana Bank and Trust’s purchase accounting entries.

NOTE 15 – STOCK-BASED COMPENSATION

At June 30, 2013, Old National had 5.1 million shares remaining available for issuance under the Company’s Amended and Restated 2008 Incentive Compensation Plan. The granting of awards to key employees is typically in the form of restricted stock awards or units.

Restricted Stock Awards

The Company granted 75 thousand time-based restricted stock awards to certain key officers during the first six months of 2013, with shares vesting at the end of a thirty-six month period. Compensation expense is recognized on a straight-line basis over the vesting period. Shares are subject to certain restrictions and risk of forfeiture by the participants. As of June 30, 2013, unrecognized compensation expense was estimated to be $1.6 million for unvested restricted share awards.

Old National recorded expense of $0.4 million, net of tax, during the first six months of 2013, compared to expense of $0.1 million during the first six months of 2012 related to the vesting of restricted share awards. Included in the first six months of 2012 is the reversal of $0.4 million of expense associated with certain performance-based restricted stock grants.

In connection with the acquisition of Indiana Community Bancorp on September 15, 2012, 15 thousand unvested Indiana Community Bancorp restricted stock awards were converted to 29 thousand unvested Old National restricted stock awards. These restricted stock awards vested December 31, 2012 upon the retirement of the participant with the remaining expense of $23 thousand accelerated into the fourth quarter of 2012.

Restricted Stock Units

The Company granted 295 thousand shares of performance based restricted stock units to certain key officers during the first six months of 2013, with shares vesting at the end of a thirty-six month period based on the achievement of certain targets. For certain awards, the level of performance could increase or decrease the percentage of shares earned. Compensation expense is recognized on a straight-line basis over the vesting period. Shares are subject to certain restrictions and risk of forfeiture by the participants.

Old National recorded $1.0 million of stock based compensation expense, net of tax, during the first six months of 2013. Old National recorded $0.7 million of stock based compensation expense, net of tax, during the first six months of 2012. Included in the first six months of 2012 is the reversal of $20 thousand of expense associated with certain performance-based restricted stock grants.

Stock Options

Old National has not granted stock options since 2009. However, in connection with the acquisition of Indiana Community Bancorp on September 15, 2012, 0.2 million options for shares of Indiana Community Bancorp stock were converted to 0.3 million options for shares of Old National Bancorp stock. Old National recorded no incremental expense associated with the conversion of these options.

Old National did not record any stock based compensation expense related to stock options during the first six months of 2013. Old National recorded $6 thousand of stock based compensation expense, net of tax, during the first six months of 2012.

NOTE 16 – INCOME TAXES

Following is a summary of the major items comprising the differences in taxes from continuing operations computed at the federal statutory rate and as recorded in the consolidated statement of income for the three and six months ended June 30:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
(dollars in thousands)	2013			2012			2013			2012
Provision at statutory rate of 35%	$	14,774		$	13,333		$	26,792		$	23,855
Tax-exempt income		(3,092	)		(2,636	)		(5,989	)		(5,146	)
State income taxes		1,156			1,133			2,372			2,027
State statutory rate change		1,257			—			1,257			—
Interim period effective rate adjustment		(358	)		(723	)		(223	)		(706	)
Other, net		(3	)		(218	)		(83	)		(801	)
Income tax expense	$	13,734		$	10,889		$	24,126		$	19,229
Effective tax rate		32.5	%		28.6	%		31.5	%		28.2	%

In accordance with ASC 740-270, Accounting for Interim Reporting, the provision for income taxes was recorded at June 30, 2013 and 2012 based on the current estimate of the effective annual rate.

For the six months ended June 30, 2013, the effective tax rate was higher than the six months ended June 30, 2012. The higher tax rate in the first six months of 2013 is the result of an increase in projected pre-tax book income while tax-exempt income remained relatively stable combined with an increase in income tax expense of approximately $1.3 million related to a statutory rate change during the second quarter of 2013.

No valuation allowance was recorded at June 30, 2013 and 2012 because, based on our current expectations, Old National believes that it will generate sufficient income in the future years to realize deferred tax assets.

Unrecognized Tax Benefits

The Company and its subsidiaries file a consolidated U.S. federal income tax return, as well as filing various state returns. Unrecognized state income tax benefits are reported net of their related deferred federal income tax benefit.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

(dollars in thousands)	2013		2012
Balance at January 1	$	3,953	$	4,145
Additions (reductions) based on tax positions related to the current year		8		1
Balance at June 30	$	3,961	$	4,146

Approximately $0.17 million of unrecognized tax benefits, if recognized, would favorably affect the effective income tax rate in future periods.

NOTE 17 – DERIVATIVE FINANCIAL INSTRUMENTS

As part of the Company’s overall interest rate risk management, Old National uses derivative instruments, including interest rate swaps, caps and floors. The notional amount of these derivative instruments was $141.0 million and $41.0 million at June 30, 2013 and December 31, 2012, respectively. The June 30, 2013 balances consist of $141.0 million notional amount of receive-fixed interest rate swaps on certain of its FHLB advances. The December 31, 2012 balances consist of $41.0 million notional amount of receive-fixed interest rate swaps on certain of its FHLB advances. These hedges were entered into to manage both interest rate risk and asset sensitivity on the balance sheet. These derivative instruments are recognized on the balance sheet at their fair value.

47

In addition, commitments to fund certain mortgage loans (interest rate lock commitments) and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At June 30, 2013, the notional amount of the interest rate lock commitments and forward commitments were $26.9 million and $36.1 million, respectively. At December 31, 2012, the notional amount of the interest rate lock commitments and forward commitments were $23.4 million and $32.0 million, respectively. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans to third party investors when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitment to fund the loans. All derivative instruments are recognized on the balance sheet at their fair value.

Old National also enters into derivative instruments for the benefit of its customers. The notional amounts of these customer derivative instruments and the offsetting counterparty derivative instruments were $449.0 million and $449.0 million, respectively, at June 30, 2013. At December 31, 2012, the notional amounts of the customer derivative instruments and the offsetting counterparty derivative instruments were $456.1 million and $456.1 million, respectively. These derivative contracts do not qualify for hedge accounting. These instruments include interest rate swaps, caps, foreign exchange forward contracts and commodity swaps and options. Commonly, Old National will economically hedge significant exposures related to these derivative contracts entered into for the benefit of customers by entering into offsetting contracts with approved, reputable, independent counterparties with substantially matching terms.

Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. Old National’s exposure is limited to the replacement value of the contracts rather than the notional, principal or contract amounts. There are provisions in our agreements with the counterparties that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed thresholds are collateralized. In addition, the Company minimizes credit risk through credit approvals, limits, and monitoring procedures.

The following tables summarize the fair value of derivative financial instruments utilized by Old National:

NOTE 18 – COMMITMENTS AND CONTINGENCIES

LITIGATION

In the normal course of business, Old National Bancorp and its subsidiaries have been named, from time to time, as defendants in various legal actions. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages.

Old National contests liability and/or the amount of damages as appropriate in each pending matter. In view of the inherent difficulty of predicting the outcome of such matters, particularly in cases where claimants seek substantial or indeterminate damages or where investigations and proceedings are in the early stages, Old National cannot predict with certainty the loss or range of loss, if any, related to such matters, how or if such matters will be resolved, when they will ultimately be resolved, or what the eventual settlement, or other relief, if any, might be. Subject to the foregoing, Old National believes, based on current knowledge and after consultation with counsel, that the outcome of such pending matters will not have a material adverse effect on the consolidated financial condition of Old National, although the outcome of such matters could be material to Old National’s operating results and cash flows for a particular future period, depending on, among other things, the level of Old National’s revenues or income for such period. Old National will accrue for a loss contingency if (1) it is probable that a future event will occur and confirm the loss and (2) the amount of the loss can be reasonably estimated.

In November 2010, Old National was named in a class action lawsuit in Vanderburgh County Circuit Court challenging Old National Bank’s checking account practices associated with the assessment of overdraft fees. The theory set forth by plaintiffs in this case is similar to other class action complaints filed against other financial institutions in recent years and settled for substantial amounts. On May 1, 2012, the plaintiff was granted permission to file a First Amended Complaint which named additional plaintiffs and amended certain claims. The plaintiffs seek damages and other relief, including restitution. On June 13, 2012, Old National filed a motion to dismiss the First Amended Complaint, which was subsequently denied by the Court. On September 7, 2012, the plaintiffs filed a motion for class certification, which was granted on March 20, 2013, and provides for a class of “All Old National Bank customers in the State of Indiana who had one or more consumer accounts and who, within the applicable statutes of limitation through August 15, 2010, incurred an overdraft fee as a result of Old National Bank’s practice of sequencing debit card and ATM transactions from highest to lowest.” Old National sought an interlocutory appeal on the issue of class certification on April 2, 2013, which was subsequently denied. Old National does not believe there is a cause of action under Indiana law to support the plaintiffs’ claims. Accordingly, on June 11, 2013, Old National moved for summary judgment and this motion is now pending with the Court. The case is currently scheduled for trial on October 7, 2013, although this trial date is subject to the completion of discovery and the ruling on the pending motion for summary judgment. Old National believes it has meritorious defenses to the claims brought by the plaintiffs. At this phase of the litigation, it is not possible for management of Old National to determine the probability of a material adverse outcome or reasonably estimate the amount of any loss.

LEASES

Old National rents certain premises and equipment under operating leases, which expire at various dates. Many of these leases require the payment of property taxes, insurance premiums, maintenance and other costs. In some cases, rentals are subject to increase in relation to a cost-of-living index. The leases have original terms ranging from less than one year to twenty-four years, and Old National has the right, at its option, to extend the terms of certain leases for four additional successive terms of five years. The Company does not have any material sub-lease agreements.

As of June 30, 2013 and 2012, Old National had $79.9 million and $87.4 million, respectively, of deferred gains remaining associated with prior sale leaseback transactions. The leases had original terms ranging from five to twenty-four years. These gains will be recognized over the remaining term of the leases.

50

CREDIT-RELATED FINANCIAL INSTRUMENTS

In the normal course of business, Old National’s banking affiliates have entered into various agreements to extend credit, including loan commitments of $1.237 billion and standby letters of credit of $71.5 million at June 30, 2013. At June 30, 2013, approximately $1.190 billion of the loan commitments had fixed rates and $47 million had floating rates, with the floating interest rates ranging from 0% to 26.25%. At December 31, 2012, loan commitments were $1.253 billion and standby letters of credit were $63.4 million. These commitments are not reflected in the consolidated financial statements. At June 30, 2013 and December 31, 2012, the balance of the allowance for unfunded loan commitments was $2.4 million and $4.0 million, respectively.

At June 30, 2013 and December 31, 2012, Old National had credit extensions of $13.7 million and $13.3 million, respectively, with various unaffiliated banks related to letter of credit commitments issued on behalf of Old National’s clients. At June 30, 2013 and December 31, 2012, Old National provided collateral to the unaffiliated banks to secure credit extensions totaling $10.4 million and $11.2 million, respectively. Old National did not provide collateral for the remaining credit extensions.

NOTE 19 – FINANCIAL GUARANTEES

Old National holds instruments, in the normal course of business with clients, that are considered financial guarantees in accordance with FASB ASC 460-10 (FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others), which requires the Company to record the instruments at fair value. Standby letters of credit guarantees are issued in connection with agreements made by clients to counterparties. Standby letters of credit are contingent upon failure of the client to perform the terms of the underlying contract. Credit risk associated with standby letters of credit is essentially the same as that associated with extending loans to clients and is subject to normal credit policies. The term of these standby letters of credit is typically one year or less. At June 30, 2013, the notional amount of standby letters of credit was $71.5 million, which represents the maximum amount of future funding requirements, and the carrying value was $0.3 million. At December 31, 2012, the notional amount of standby letters of credit was $63.4 million, which represents the maximum amount of future funding requirements, and the carrying value was $0.4 million.

During the second quarter of 2007, Old National entered into a risk participation in an interest rate swap. The interest rate swap had a notional amount of $8.3 million at June 30, 2013.

NOTE 20 – SEGMENT INFORMATION

Old National operates in two operating segments: community banking and treasury. The community banking segment serves customers in both urban and rural markets providing a wide range of financial services including commercial, real estate and consumer loans; lease financing; checking, savings, time deposits and other depository accounts; cash management services; and debit cards and other electronically accessed banking services and Internet banking. Treasury manages investments, wholesale funding, interest rate risk, liquidity and leverage for Old National. Additionally, treasury provides other miscellaneous capital markets products for its corporate banking clients. Other is comprised of the parent company, the purchased credit impaired loan portfolio, and several smaller business units including insurance, wealth management and brokerage. It includes unallocated corporate overhead and intersegment revenue and expense eliminations.

In order to measure performance for each segment, Old National allocates capital and corporate overhead to each segment. Capital and corporate overhead are allocated to each segment using various methodologies, which are subject to periodic changes by management. Intersegment sales and transfers are not significant.

Old National uses a funds transfer pricing (“FTP”) system to eliminate the effect of interest rate risk from net interest income in the community banking segment and from companies included in the “other” column. The FTP system is used to credit or charge each segment for the funds the segments create or use. The net FTP credit or charge is reflected in segment net interest income.

The financial information for each operating segment is reported on the basis used internally by Old National’s management to evaluate performance and is not necessarily comparable with similar information for any other financial institution.

Included in net interest income for the three and six months ended June 30, 2013 in the Community Banking segment is approximately $9.8 million and $18.5 million, respectively, associated with Indiana Community Bancorp (“IBT”), acquired on September 15, 2012. Included in noninterest income for the three and six months ended June 30, 2013 in the Community Banking segment is approximately $2.1 million and $4.2 million, respectively, associated with the acquisition of IBT.

Noninterest expense for the six months ended June 30, 2013 includes $1.0 million of costs in the Community Banking segment associated with the acquisition of IBT.

Provision for loan losses resulted in recapture during the three and six months ended June 30, 2013. The recapture recorded in the Community Banking segment was primarily a result of the continuing trend in improved credit quality and the lower loss rates applied to the performing loan portfolio as charge-offs continue to decrease over time.

The recapture of provision expense recorded in the “Other” segment during the three and six months ended June 30, 2013 was reflective of recoveries associated with the purchased credit impaired loan portfolio accounted for in accordance with ASC-310-30. The provision for loan losses in this segment during 2012 related primarily to our FDIC-assisted transaction which closed in July 2011.

NOTE 21 – FAIR VALUE

FASB ASC 820-10 defines fair value as 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. FASB ASC 820-10 also establishes a 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. The standard describes 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 that the entity has the ability to access as of the measurement date.

• 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; or 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.

Old National used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Investment securities: The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). 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 (Level 3). Discounted cash flows are calculated using swap and libor curves plus spreads that adjust for loss severities, volatility, credit risk 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.

Residential loans held for sale: The fair value of loans held for sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan (Level 2).

Derivative financial instruments: The fair values of derivative financial instruments are based on derivative valuation models using market data inputs as of the valuation date (Level 2).

(a) Assuming no prepayments.

(b) Each currently performing pool asset is assigned a default probability based on the banking environment, which is adjusted for specific issuer evaluation, of 0%, 50% or 100%.

(c) Each currently defaulted pool asset is assigned a recovery probability based on specific issuer evaluation of 0%, 25% or 100%.

The significant unobservable inputs used in the fair value measurement for pooled trust preferred securities are prepayment rates, assumed additional pool asset defaults and expected return to performing status of defaulted pool assets. Significant changes in any of the inputs in isolation would result in a significant change to the fair value measurement. Three of the five pooled trust preferred securities Old National owns are subordinate note classes that rely on an ongoing cash flow stream to support their values. The senior note classes receive the benefit of prepayments to the detriment of subordinate note classes since the ongoing interest cash flow stream is reduced by the early redemption. Generally, a change in prepayment rates or additional pool asset defaults has an impact that is directionally opposite from a change in the expected recovery of a defaulted pool asset.

Impaired commercial and commercial real estate loans that are deemed collateral dependent are valued based on the fair value of the underlying collateral. These estimates are based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These impaired commercial and commercial real estate loans had a principal amount of $32.5 million, with a valuation allowance of $7.2 million at June 30, 2013. Old National recorded $3.9 million of provision expense associated with these loans for the six months ended June 30, 2013.

Other real estate owned and other repossessed property is measured at fair value less costs to sell and had a net carrying amount of $21.6 million. The estimates of fair value are based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These appraisals are discounted 0% to 45% depending on the type of property and the type of appraisal (market value vs. liquidation value). There were net write-downs of other real estate owned of $2.1 million in the first six months of 2013.

56

During the second quarter of 2013, finance leases of $11.6 million were transferred from the commercial loan category at fair value, which is the offer price, and a loss of $0.2 million was recognized.

Collateral dependent loans, other real estate owned and other repossessed property are valued based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These appraisals are discounted depending on the type of property and the type of appraisal (market value vs. liquidation value).

Financial instruments recorded using fair value option

Under FASB ASC 825-10, the Company may elect to report most financial instruments and certain other items at fair value on an instrument-by instrument basis with changes in fair value reported in net income. After the initial adoption, the election is made at the acquisition of an eligible financial asset, financial liability or firm commitment or when certain specified reconsideration events occur. The fair value election may not be revoked once an election is made.

57

The Company has elected the fair value option for residential mortgage loans held for sale. For these loans, interest income is recorded in the consolidated statements of income based on the contractual amount of interest income earned on the financial assets (except any that are on nonaccrual status). None of these loans are 90 days or more past due, nor are any on nonaccrual status. Included in the income statement are $105 thousand and $206 thousand of interest income for residential loans held for sale for the three and six months ended June 30, 2013, respectively. Included in the income statement are $34 thousand and $65 thousand of interest income for residential loans held for sale for the three and six months ended June 30, 2012, respectively.

Residential mortgage loans held for sale

Old National has elected the fair value option for newly originated conforming fixed-rate and adjustable-rate first mortgage loans held for sale. These loans are intended for sale and are hedged with derivative instruments. Old National has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplification. The fair value option was not elected for loans held for investment.

As of June 30, 2013, the difference between the aggregate fair value and the aggregate remaining principal balance for loans for which the fair value option has been elected is as follows. Accrued interest at period end is included in the fair value of the instruments.

The following methods and assumptions were used to estimate the fair value of each type of financial instrument.

Cash, due from banks, federal funds sold and resell agreements and money market investments: For these instruments, the carrying amounts approximate fair value (Level 1).

Investment securities: Fair values for investment securities held-to-maturity are based on quoted market prices, if available. For securities where quoted prices are not available, fair values are estimated based on market prices of similar securities (Level 2).

Federal Home Loan Bank Stock: Old National Bank is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. The carrying value of Federal Home Loan Bank stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank (Level 2).

61

Loans: The fair value of loans is estimated by discounting future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities (Level 3).

Covered loans: Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting current market rates for new originations of comparable loans adjusted for the risk inherent in the cash flow estimates. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques (Level 3).

FDIC indemnification asset: The loss sharing asset was measured separately from the related covered assets as it is not contractually embedded in the assets and is not transferable with the assets should the Bank choose to dispose of the assets. Fair value was originally estimated using projected cash flows related to the loss sharing agreement based on the expected reimbursements for losses and the applicable loss sharing percentage and these projected cash flows are updated with the cash flow estimates on covered assets. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC (Level 3).

Accrued interest receivable and payable: The carrying amount approximates fair value and is aligned with the underlying assets or liabilities (Level 1, Level 2 or Level 3).

Deposits: The fair value of noninterest-bearing demand deposits and savings, NOW and money market deposits is the amount payable as of the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit is estimated using rates currently offered for deposits with similar remaining maturities (Level 2).

Short-term borrowings: Federal funds purchased and other short-term borrowings generally have an original term to maturity of 30 days or less and, therefore, their carrying amount is a reasonable estimate of fair value (Level 1). The fair value of securities sold under agreements to repurchase is determined using end of day market prices (Level 1).

Other borrowings: The fair value of medium-term notes, subordinated debt and senior bank notes is determined using market quotes (Level 2). The fair value of FHLB advances is determined using calculated prices for new FHLB advances with similar risk characteristics (Level 3). The fair value of other debt is determined using comparable security market prices or dealer quotes (Level 2).

Standby letters of credit: Fair values for standby letters of credit are based on fees currently charged to enter into similar agreements. The fair value for standby letters of credit was recorded in “Accrued expenses and other liabilities” on the consolidated balance sheet in accordance with FASB ASC 460-10 (FIN 45) (Level 3).

Off-balance sheet financial instruments: Fair values for off-balance sheet credit-related financial instruments are based on fees currently charged to enter into similar agreements. For further information regarding the amounts of these financial instruments, see Notes 18 and 19.

PART I. FINANCIAL INFORMATION

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion is an analysis of our results of operations for the three and six months ended June 30, 2013 and 2012, and financial condition as of June 30, 2013, compared to June 30, 2012, and December 31, 2012. This discussion and analysis should be read in conjunction with the consolidated financial statements and related notes. This discussion contains forward-looking statements concerning our business that are based on estimates and involves certain risks and uncertainties. Therefore, future results could differ significantly from our current expectations and the related forward-looking statements.

EXECUTIVE SUMMARY

During the second quarter of 2013, net income was $28.5 million, or $0.28 per share. This compares to the $27.2 million, or $0.29 per share reported in the second quarter of 2012. The increase in net income year over year is primarily the result of our acquisition of Indiana Community Bancorp which closed on September 15, 2012. Earnings per share comparisons are impacted by the 6.6 million shares issued during the third quarter of 2012 in conjunction with our acquisition of Indiana Community Bancorp.

Although loan growth remains tempered, total loan balances did increase $64.2 million from March 31, 2013. The largest increase was in the commercial loan portfolio. Although we believe we are in the midst of a macro recovery, the steeper yield curve could contribute to a slowdown of refinancing activity and weaker loan growth.

Management continues to focus on expenses and announced plans to consolidate eighteen additional banking centers. As part of an ongoing efficiency initiative, Old National continues to examine its locations closely, reviewing such items as market dynamics, deposits per branch, proximity to other offices and client traffic. The centers are scheduled to be closed in the third quarter of 2013.

Credit quality continues to improve with quarterly net charge offs to average loans of 0.04% at June 30, 2013 compared to 0.13% a year ago. These lower loss rates, along with continuing improvement in asset quality, contributed to recapture of $3.7 million of provision expense during the quarter. Non-performing loans to total loans improved to 3.84% compared to 5.13% at June 30, 2012.

Subsequent to quarter end the Company closed on its acquisition of 24 Bank of America branches in northern Indiana and the southwest Michigan market. Included in the transaction were approximately $575.0 million in deposits and $5.0 million in loans. The Company’s total assets remain below $10.0 billion and the Company will not be subject to certain provisions of the Dodd Frank Act as a result of this transaction. Management will continue to actively pursue partnership opportunities to improve our deposit franchise within or contiguous to our geographic operating footprint.

Tier 1 leverage ratio		8.80			9.00						8.80			9.00
Net charge-offs to average loans		0.04			0.13						0.10			0.24

(1) Efficiency ratio is defined as noninterest expense before amortization of intangibles as a percent of fully taxable net interest income and noninterest income, excluding net gains from securities transactions. This presentation excludes intangible amortization and net securities gains, as is common in other company disclosures, and better aligns with true operating performance. This is a non-GAAP financial measure that management believes to be helpful in understanding Old National’s results of operations.

Net Interest Income

Net interest income is our most significant component of earnings, comprising over 63% of revenues at June 30, 2013. Net interest income and margin are influenced by many factors, primarily the volume and mix of earning assets, funding sources and interest rate fluctuations. Other factors include level of accretion income on purchased loans, prepayment risk on mortgage and investment-related assets and the composition and maturity of earning assets and interest-bearing liabilities. Loans typically generate more interest income than investment securities with similar maturities. Funding from client deposits generally cost less than wholesale funding sources. Factors such as general economic activity, Federal Reserve Board monetary policy and price volatility of competing alternative investments, can also exert significant influence on our ability to optimize the mix of assets and funding and the net interest income and margin.

Net interest income is the excess of interest received from earning assets over interest paid on interest-bearing liabilities. For analytical purposes, net interest income is also presented in the table that follows, adjusted to a taxable equivalent basis to reflect what our tax-exempt assets would need to yield in order to achieve the same after-tax yield as a taxable asset. We used the federal statutory tax rate in effect of 35% for all periods adjusted for the TEFRA interest disallowance applicable to certain tax-exempt obligations. This analysis portrays the income tax benefits associated in tax-exempt assets and helps to facilitate a comparison between taxable and tax-exempt assets. Management believes that it is a standard practice in the banking industry to present net interest margin and net interest income on a fully taxable equivalent basis. Therefore, management believes these measures provide useful information for both management and investors by allowing them to make peer comparisons.

	Three Months Ended						Six Months Ended
	June 30,						June 30,
(dollars in thousands)	2013			2012			2013			2012
Net interest income	$	79,191		$	75,973		$	158,241		$	150,246
Taxable equivalent adjustment		4,243			3,252			8,155			6,303
Net interest income—taxable equivalent	$	83,434		$	79,225		$	166,396		$	156,549
Average earning assets	$	8,406,635		$	7,440,566		$	8,308,580		$	7,401,333
Net interest margin		3.77	%		4.08	%		3.81	%		4.06	%
Net interest margin—fully taxable equivalent		3.97	%		4.26	%		4.01	%		4.23	%

Net interest income was $79.2 million and $158.2 million for the three and six months ended June 30, 2013, up from the $76.0 million and $150.2 million reported for the three and six months ended June 30, 2012. Taxable equivalent net interest income was $83.4 million and $166.4 million for the three and six months ended June 30, 2013, up from the $79.2 million and $156.5 million reported for the three and six months ended June 30, 2012. The net interest margin on a fully taxable equivalent basis was 3.97% and 4.01% for the three and six months ended June 30, 2013, compared to 4.26% and 4.23% for the three and six months ended June 30, 2012. The increase in net interest income is primarily due to the acquisition of Indiana Community Bancorp (“IBT”) on September 15, 2012, combined with a change in the mix of interest earning assets and interest-bearing liabilities. The accretion associated with the purchased assets from IBT benefited net interest margin by $6.1 million and $11.2 million, or 29 and 27 basis points, during the three and six months ended June 30, 2013, respectively. We expect this accretion income to decline over time. The decrease in the net interest margin is primarily due to the yield on average earning assets decreasing faster than the cost of interest-bearing liabilities. The yield on interest earning assets decreased 49 basis points while the cost of interest-bearing liabilities decreased 27 basis points in the quarterly year-over-year comparison. In the year-to-date comparison, the yield on interest earning assets decreased 41 basis points while the cost of interest-bearing liabilities decreased 26 basis points.

Average earning assets were $8.407 billion for the three months ended June 30, 2013, compared to $7.441 billion for the three months ended June 30, 2012, an increase of 13.0%, or $966.1 million. Average earning assets were $8.309 billion for the six months ended June 30, 2013, compared to $7.401 billion for the six months ended June 30, 2012, an increase of 12.3%, or $907.2 million. Included in average earning assets for the six months ended June 30, 2013 is approximately $366.4 million from the Indiana Community Bancorp acquisition, which was acquired on September 15, 2012. Significantly affecting average earning assets at June 30, 2013 compared to June 30, 2012, was the increase in the size of the loan portfolio combined with an increase in the size of the investment portfolio. Year over year, the investment portfolio, which generally has an average yield lower than the loan portfolio, has increased as a percent of interest earning assets and was approximately 37% of interest earning assets at June 30, 2013.

The $468.3 million increase in average loans is primarily a result of the remaining $366.0 million of average loans acquired in the IBT acquisition. We have continued to experience growth in our commercial loan and residential mortgage loan portfolios, but continue to experience declines in our acquired loan portfolios.

The $447.9 million increase in the investment portfolio was in anticipation of the pending Bank of America branch acquisition. Old National began buying securities starting in the first quarter of 2013 when rates were favorable in advance of the close in July of 2013. The transaction received regulatory approval and we acquired approximately $542 million of cash and assumed approximately $575 million of deposits on July 12, 2013. The investment purchases had been funded with short term borrowings and FHLB advances with short maturities which were retired when the cash was received. The Company currently expects it will remain below $10 billion in assets and will not be subject to certain provisions of the Dodd-Frank Act.

65

Positively affecting margin were increases in noninterest-bearing demand deposits, short-term borrowings and FHLB advances with short maturities combined with a decrease in time deposits. The increase in short-term borrowings and FHLB advances, as discussed above, was in anticipation of the branch acquisition from Bank of America. Approximately $537 million of short-term borrowings and FHLB advances were repaid on July 12, 2013 when the transaction closed. Over the past year, we have reduced the cost of our other borrowings by changing the composition of other borrowings. During the first six months of 2013, we terminated $50.0 million of FHLB advances. We also restructured $33.4 million of FHLB advances in the first quarter of 2013. During the fourth quarter of 2012, we terminated $50.0 million of FHLB advances. On June 30, 2012 we redeemed $13.0 million of subordinated notes and $3.0 million of trust preferred securities. Year over year, time deposits, which have an average interest rate higher than other types of deposits, have decreased as a percent of total funding. Year over year, short-term borrowings, which have an average interest rate lower than many types of funding, have increased as a percent of total funding.

Provision for Loan Losses

The provision for loan losses was a credit of $3.7 million for the three months ended June 30, 2013, compared to $0.4 million of expense for the three months ended June 30, 2012. The provision for loan losses was a credit of $2.8 million for the six months ended June 30, 2013, compared to $2.4 million of expense for the six months ended June 30, 2012. Impacting the provision over the past twelve months are the following factors: (1) the loss factors applied to our performing loan portfolio have decreased over time as charge-offs were substantially lower, (2) the continuing trend in improved credit quality, and (3) the percentage of our legacy loan portfolio consisting of those loans where higher loss factors are applied (commercial and commercial real estate loans) is increasing at a slower pace than the percentage of our loan portfolio consisting of those loans where lower loss factors are applied (residential loans).

Noninterest Income

We generate revenues in the form of noninterest income through client fees and sales commissions from our core banking franchise and other related businesses, such as wealth management, investment consulting, investment products and insurance. Noninterest income for the three months ended June 30, 2013 was $46.2 million, a decrease of $2.3 million, or 4.7%, from the $48.5 million reported for the three months ended June 30, 2012. For the six months ended June 30, 2013, noninterest income was $92.6 million, a decrease of $5.1 million, or 5.2%, from the $97.7 million reported for the six months ended June 30, 2012. The decrease is primarily the result of adjustments to the FDIC indemnification asset and a decrease in service charges on deposit accounts. Partially offsetting these decreases were increases from insurance premiums and commissions and the gain on branch divestitures.

Net securities gains were $1.8 million and $2.8 million for the three and six months ended June 30, 2013, compared to net securities gains of $6.2 million and $6.7 million for the three and six months ended June 30, 2012. Included in the second quarter and first six months of 2012 are securities gains of $7.0 million and $7.6 million, respectively. Partially offsetting these gains in 2012 were other-than-temporary-impairment charges of $0.8 million and $0.9 million, respectively, on five non-agency mortgage-backed securities and one trust preferred security.

Wealth management fees, which are dependent on the managed assets performance, continue to be impacted by uncertainties in the investment markets. Wealth management fees did increase by $1.1 million to $12.1 million in the first six months of 2013, primarily due to the acquisition of Indiana Community Bancorp on September 15, 2012.

Service charges and overdraft fees on deposit accounts, our largest source of noninterest income, continued to decline. Service charges and overdraft fees were $11.8 million for the three months ended June 30, 2013, compared to $12.9 million for the three months ended June 30, 2012. Service charges and overdraft fees were $22.9 million for the six months ended June 30, 2013, compared to $25.8 million for the six months ended June 30, 2012. For the six months ended June 30, 2013, the decrease is primarily attributable to a $4.2 million decrease in overdraft charges, which was partially offset by a $1.1 million increase associated with the acquisition of Indiana Community Bancorp. The net decrease of $3.1 million is primarily due to changes in customer behavior.

Mortgage banking revenue was $1.6 million and $2.9 million for the three and six months ended June 30, 2013, compared to $0.8 million and $1.3 million for the three and six months ended June 30, 2012. Mortgage banking revenue increased primarily as a result of an increase in gain on sale of loans, as we sold more production to the secondary market in 2013.

66

Insurance premiums and commissions increased $1.4 million to $20.3 million for the six months ended June 30, 2013, as compared to $18.9 million for the six months ended June 30, 2012, primarily as a result of higher contingency income and commissions on property and casualty insurance.

Investment product fees were $4.1 million and $7.7 million for the three and six months ended June 30, 2013, compared to $3.2 million and $6.1 million for the three and six months ended June 30, 2012. The increase is primarily as a result of increases in annuity fees and mutual fund fees.

During the third quarter of 2012, Old National announced plans to sell the deposits of nine banking centers in southern Illinois and western Kentucky. The sales closed during the first quarter of 2013. Deposits at the time of sale were approximately $150.1 million and we received a deposit premium of $2.2 million on the sales.

Other income decreased $1.8 million and $1.2 million for the three and six months ended June 30, 2013 as compared to the three and six months ended June 30, 2012. The decreases are primarily a result of a decrease in gain on sales of foreclosed properties partially offset by an increase in customer derivative fee revenue.

Noninterest Income Related to Covered Assets

Income and expense associated with the FDIC loss sharing agreements is reflected in the change in the FDIC indemnification asset. This balance includes discount accretion, gains on the write-up of the FDIC indemnification asset, and expense from the reduction of the FDIC indemnification asset upon the removal of loans, OREO and unfunded loan commitments. Loans are removed when they have been fully paid off, fully charged off, sold or transferred to OREO. The change in the FDIC indemnification asset also includes income due to the FDIC, as well as the income statement effects of other loss share transactions.

For the second quarter of 2013, adjustments to the FDIC indemnification asset resulted in noninterest expense of $1.5 million. This compares to noninterest expense of $4.0 million during the second quarter of 2012. The second quarter of 2012 included a $4.3 million decrease in cash flows expected from the indemnification asset due primarily to improvement in loan loss expectations.

During the first six months of 2013, adjustments to the FDIC indemnification asset resulted in $3.8 million of noninterest expense. During the first six months of 2012, adjustments to the FDIC indemnification asset resulted in $0.8 million of noninterest income. The first six months of 2012 included $8.1 million of income associated with the impairment of covered other real estate owned, compared to $1.0 million of income associated with impairment of covered other real estate owned in the first six months of 2013.

Noninterest Expense

Noninterest expense for the three months ended June 30, 2013, totaled $86.9 million, an increase of $0.9 million, or 1.0%, from the $86.0 million recorded for the three months ended June 30, 2012. For the six months ended June 30, 2013, noninterest expense totaled $177.1 million, a decrease of $0.2 million, or 0.1%, from the $177.3 million recorded for the six months ended June 30, 2012. Included in the three and six months ended June 30, 2013 is approximately $1.3 million and $2.7 million of noninterest expense related to Indiana Community Bancorp, which was acquired on September 15, 2012.

Salaries and benefits is the largest component of noninterest expense. For the three months ended June 30, 2013, salaries and benefits were $48.7 million compared to $46.8 million for the three months ended June 30, 2012. For the six months ended June 30, 2013, salaries and benefits were $99.7 million compared to $92.8 million for the six months ended June 30, 2012. Included in the second quarter of 2013 is an increase of $1.1 million for salaries and benefits expense associated with former IBT associates. Also included in the second quarter of 2013 is a $0.8 million increase in hospitalization expense. Included in the first six months of 2013 is an increase of $2.3 million for salaries and benefits expense associated with former IBT associates. Also included in the first six months of 2013 is a $1.3 million increase in performance-based incentive compensation, a $1.8 million increase in hospitalization expense and a $1.0 million increase in commission expense.

67

Occupancy expense was $12.0 million and $24.1 million for the three and six months ended June 30, 2013, compared to $13.3 million and $25.7 million for the three and six months ended June 30, 2012. Decreases in rent expense and building depreciation associated with our recent branch closures and consolidations were the primary reasons for the decrease in occupancy expense.

Professional fees increased $1.1 million for the six months ended June 30, 2013, compared to the six months ended June 30, 2012. The increase is primarily attributable to other professional fees associated with the BSA/AML consent order. Continued compliance with the June 4, 2012, consent order issued by our primary regulator resulted in increased professional fees during the first six months of 2013 as the Company continues to progress on this project. The consent order requires the Bank to, among other things: continue to review, update, and implement a written institution-wide, ongoing BSA/AML risk assessment that accurately identifies BSA/AML risks; ensure that Bank management reviews, updates, and implements its risk-based processes to obtain and analyze appropriate customer due diligence information to monitor for and investigate suspicious activity; ensure adherence to a written program for appropriate identification, analyzing and monitoring of transactions with greater than normal risk; maintain an effective BSA independent testing function; and ensure and maintain sufficient personnel with requisite expertise and skills who receive adequate on-going training. These costs were partially offset by a decrease in legal fees.

FDIC assessment expense decreased $1.3 million and $1.0 million for the three and six months ended June 30, 2013 as compared to the three and six months ended June 30, 2012. The decreases are primarily a result of a decrease in the assessment rate due to the amending of certain call reports.

Other real estate owned expense was $1.5 million and $2.6 million for the three and six months ended June 30, 2013, compared to $1.6 million and $11.4 million for the three and six months ended June 30, 2012. The majority of the 2012 expense was associated with other real estate properties acquired from the FDIC; 80% of which was offset by a corresponding adjustment to the FDIC indemnification asset.

Amortization of intangibles was $4.4 million for the six months ended June 30, 2013, compared to $3.9 million for the six months ended June 30, 2012. The increase is primarily due to an adjustment to core deposit intangible amortization expense related to the sale of the nine branches during the first quarter of 2013.

Other expense was $4.1 million and $8.3 million for the three and six months ended June 30, 2013, compared to $3.4 million and $5.3 million for the three and six months ended June 30, 2012. Included in expense for 2013 is approximately $1.0 million for loss on extinguishment of debt regarding the termination of $50.0 million of FHLB advances and an increase of approximately $0.9 million related to writedowns on branches that were sold.

Noninterest Expense Related to Covered Assets

Noninterest expense related to covered assets are included in OREO expense, legal and professional expense and other covered asset-related expenses, and may be subject to FDIC reimbursement. Expenses must meet certain FDIC criteria in order for the expense amounts to be reimbursed. Certain amounts reflected in these balances may not be reimbursed by the FDIC if they do not meet the criteria.

$238 thousand, or twenty percent of the expense associated with holding and maintaining covered assets assumed in the Integra acquisition, are not reimbursable by the FDIC and were recorded as noninterest expense during the first six months of 2013. The remaining eighty percent was recorded as a receivable from the FDIC. Additional non-reimbursable expenses of $188 thousand associated with holding and maintaining covered assets assumed in the Integra acquisition were also recorded in noninterest expense during the first six months of 2013.

$504 thousand, or twenty percent of the expense associated with holding and maintaining covered assets assumed in the Integra acquisition, are not reimbursable by the FDIC and were recorded as noninterest expense during the first six months of 2012. The remaining eighty percent was recorded as a receivable from the FDIC. Additional non-reimbursable expenses of $219 thousand associated with holding and maintaining covered assets assumed in the Integra acquisition were also recorded in noninterest expense during the first six months of 2012.

Provision for Income Taxes

We record a provision for income taxes currently payable and for income taxes payable or benefits to be received in the future, which arise due to timing differences in the recognition of certain items for financial statement and income tax purposes. The major difference between the effective tax rate applied to our financial statement income and the federal statutory tax rate is caused by interest on tax-exempt securities and loans. The provision for income taxes, as a percentage of pre-tax income, was 32.5% for the three months ended June 30, 2013, compared to 28.6% for the three months ended June 30, 2012. The provision for income taxes, as a percentage of pre-tax income, was 31.5% for the six months ended June 30, 2013, compared to 28.2% for the six months ended June 30, 2012. In accordance with ASC 740-270, Accounting for Interim Reporting, the provision for income taxes was recorded at June 30, 2013 based on the current estimate of the effective annual rate. The higher tax rate in the second quarter and six months of 2013 is the result of an increase in projected pre-tax book income while tax-exempt income remained relatively stable combined with an increase in income tax expense of approximately $1.3 million related to a change in Indiana tax rates and resulting adjustment to the deferred tax asset. See Note 16 to the consolidated financial statements for additional information.

FINANCIAL CONDITION

Overview

At June 30, 2013, our assets were $9.641 billion, an 11.0% increase compared to June 30, 2012 assets of $8.690 billion, and an increase of 1.0% compared to December 31, 2012 assets of $9.544 billion. The increase in assets is primarily the result of an increase in the investment portfolio in anticipation of the acquisition of 24 branches from Bank of America in the third quarter of 2013 and an increase in the loan portfolio from June 30, 2012, which is primarily a result of the acquisition of Indiana Community Bancorp during the third quarter of 2012. Year over year, we have reduced our reliance on higher cost deposits. Time deposits, which have an average interest rate higher than other types of deposits, have decreased as a percent of total funding. Year over year, short-term borrowings, which have an average interest rate lower than many types of funding, have increased as a percent of total funding.

Earning Assets

Our earning assets are comprised of investment securities, portfolio loans, loans held for sale, money market investments, interest earning accounts with the Federal Reserve and trading securities. Earning assets were $8.367 billion at June 30, 2013, an increase of 11.2% from June 30, 2012.

Investment Securities

We classify the majority of our investment securities as available-for-sale to give management the flexibility to sell the securities prior to maturity if needed, based on fluctuating interest rates or changes in our funding requirements. However, we do have $44.3 million of 15- and 20-year fixed-rate mortgage-backed securities, $172.3 million of U.S. government-sponsored entity and agency securities and $184.5 million of state and political subdivision securities in our held-to-maturity investment portfolio at June 30, 2013. During the third quarter of 2012, approximately $46.1 million of state and political subdivision securities were transferred from the held-to-maturity portfolio to the available-for-sale portfolio due to changes in circumstances associated with the Office of Management and Budget’s report outlining sequestration and the implications for taxable Build America Bonds. See Note 6 to the consolidated financial statements for additional details.

Trading securities, which consist of mutual funds held in a trust associated with deferred compensation plans for former Monroe Bancorp directors and executives, are recorded at fair value and totaled $3.3 million at June 30, 2013 compared to $2.9 million at June 30, 2012.

At June 30, 2013, the total investment securities portfolio was $3.104 billion compared to $2.706 billion at June 30, 2012, an increase of $398.1 million or 14.7%. Investment securities increased $159.4 million compared to December 31, 2012, an increase of 5.4%. Investment securities represented 37.1% of earning assets at June 30, 2013, compared to 36.0% at June 30, 2012, and 35.9% at December 31, 2012. The increase in the investment portfolio is in anticipation of the acquisition of the 24 branches from Bank of America. The transaction has received regulatory approval and closed on July 12, 2013. Stronger commercial loan demand in the future and management’s efforts to deleverage the balance sheet could result in a reduction in the securities portfolio. As of June 30, 2013, management does not intend to sell any securities with an unrealized loss position and does not believe the Company will be required to sell such securities.

The investment securities available-for-sale portfolio had net unrealized losses of $26.2 million at June 30, 2013, a decrease of $78.6 million compared to net unrealized gains of $52.4 million at June 30, 2012, and a decrease of $90.2 million compared to net unrealized gains of $64.0 million at December 31, 2012. The decrease is a result of the increase in interest rates that occurred during the second quarter. No other-than-temporary-impairment charge was recorded during the first six months of 2013. A $0.9 million charge was recorded during the first six months of 2012 related to other-than-temporary-impairment on five non-agency mortgage-backed securities and one trust preferred security. See the consolidated statements of comprehensive income for the impact of other-than-temporary-impairment in other comprehensive income and Note 6 to the consolidated financial statements for details on management’s evaluation of securities for other-than-temporary-impairment.

The investment portfolio had an average duration of 4.73 at June 30, 2013, compared to 3.87 at June 30, 2012, and 3.71 at December 31, 2012. Effective duration measures the percentage change in value of the portfolio in response to a change in interest rates. Generally, there is more uncertainty in interest rates over a longer average maturity, resulting in a higher duration percentage. The annualized average yields on investment securities, on a taxable equivalent basis, were 2.89% for the three months ended June 30, 2013, compared to 3.27% for the three months ended June 30, 2012, and 3.02% for the three months ended December 31, 2012. Average yields on investment securities, on a taxable equivalent basis, were 2.92%, 3.30% and 3.21% for the six months ended June 30, 2013 and 2012 and for the year ended December 31, 2012.

Residential Loans Held for Sale

Residential loans held for sale were $13.6 million at June 30, 2013, compared to $4.4 million at June 30, 2012, and $12.6 million at December 31, 2012. At June 30, 2013, loans held for sale was made up entirely of mortgage loans held for immediate sale in the secondary market with servicing released. These loans are sold at or prior to origination at a contracted price to an outside investor on a best efforts basis and remain on the Company’s balance sheet for a short period of time (typically 30 to 60 days). These loans are sold without recourse and Old National has experienced no material losses. Mortgage originations are subject to volatility due to interest rates and home sales.

We have elected the fair value option under FASB ASC 825-10 (SFAS No. 159) prospectively for residential loans held for sale. The aggregate fair value was $0.3 million less than the unpaid principal balance as of June 30, 2013. The aggregate fair value exceeded the unpaid principal balance by $0.1 million as of June 30, 2012. At December 31, 2012, the aggregate fair value exceeded the unpaid principal balances by $0.4 million.

Finance Leases Held for Sale

At June 30, 2013, Old National had taxable finance leases held for sale of $11.6 million. These leases were transferred from the commercial loan category at fair value and a loss of $0.2 million was recognized. The portfolio of leases held for sale has an average maturity of 2.7 years and interest rates ranging from 3.57% to 10.22%. The leases held for sale are to a variety of borrowers, with various types of equipment securing the leases, and all of the leases are current. Old National does not intend to sell its nontaxable leases.

Commercial and Commercial Real Estate Loans

Commercial and commercial real estate loans, including covered loans, are the second largest classification within earning assets, representing 33.1% of earning assets at June 30, 2013, a decrease from 34.4% at June 30, 2012, and a decrease from 34.5% at December 31, 2012. At June 30, 2013, commercial and commercial real estate loans, including covered loans, were $2.766 billion, an increase of $180.1 million since June 30, 2012, and a decrease of $65.3 million since December 31, 2012. Included in the total for June 30, 2013 is approximately $195.4 million related to our acquisition of Indiana Community Bancorp. Loan demand in our markets remains soft. However, if you exclude covered loans and the recently acquired IBT loans, we did experience modest loan growth in the commercial portfolio during the past twelve months.

Consumer Loans

At June 30, 2013, consumer loans, including automobile loans, personal and home equity loans and lines of credit, increased $12.0 million or 1.2% compared to June 30, 2012, and decreased $26.1 million or 2.6% since December 31, 2012. Included in the total for June 30, 2013 is approximately $62.4 million related to our acquisition of Indiana Community Bancorp.

Residential Real Estate Loans

At June 30, 2013, residential real estate loans, including covered loans, held in our loan portfolio were $1.432 billion, an increase of $71.0 million, or 5.2%, from December 31, 2012 and an increase of $268.4 million, or 23.1%, from June 30, 2012. In addition to organic loan production, June 30, 2013 totals also include approximately $77.4 million acquired from Indiana Community Bancorp. The majority of the growth in residential real estate loans began in the fourth quarter of 2010, primarily as a result of a new mortgage product that was introduced. At June 30, 2013, this new product had an average FICO score of 779, an average loan to value ratio of 60% and an average duration of 17.6 years. We have also retained more of our loan originations to partially offset the slow loan demand from our traditional commercial customers.

Covered Assets

On July 29, 2011, Old National acquired the banking operations of Integra Bank N.A. (“Integra”) in an FDIC assisted transaction. The Company entered into separate loss sharing agreements with the FDIC providing for specified credit loss protection for substantially all acquired single family residential loans, commercial loans, and other real estate owned (“OREO”). Loans comprise the majority of the assets acquired and are subject to loss share agreements with the FDIC whereby Old National is indemnified against 80% of losses up to $275.0 million, losses in excess of $275.0 million up to $467.2 million at 0% reimbursement, and 80% of losses in excess of $467.2 million with respect to covered assets. As of June 30, 2013, we do not expect losses to exceed $275.0 million.

A summary of covered assets is presented below:

	June 30,		December 31,
(dollars in thousands)	2013		2012
Loans, net of discount & allowance	$	283,149	$	366,617
Other real estate owned		23,131		26,137
Total covered assets	$	306,280	$	392,754

FDIC Indemnification Asset

Because the FDIC will reimburse Old National for losses incurred on certain acquired loans, an indemnification asset is recorded at fair value at the acquisition date. The indemnification asset is recognized at the same time as the indemnified loans, and measured on the same basis, subject to collectibility or contractual limitations. The indemnification asset, on the acquisition date, reflects the reimbursements expected to be received from the FDIC, using an appropriate discount rate, which reflects counterparty credit risk and other uncertainties. Reimbursement claims are submitted to the FDIC and the receivable is reduced when the FDIC pays the claim. At June 30, 2013, the FDIC indemnification asset was $100.4 million and was comprised of an $89.6 million FDIC indemnification asset and a $10.8 million FDIC loss share receivable. The loss share receivable represents actual incurred losses where reimbursement has not yet been received from the FDIC. The indemnification asset represents future cash flows the Company expects to collect from the FDIC under the loss sharing agreements and the amount related to the estimated improvements in cash flow expectations that are being amortized over the same period for which those improved cash flows are being accreted into income. At June 30, 2013, $63.8 million of the FDIC indemnification asset related to expected indemnification payments and $25.8 million is expected to be amortized and reported in noninterest income as an offset to future accreted interest income.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets at June 30, 2013, totaled $364.4 million, an increase of $81.0 million compared to $283.4 million at June 30, 2012, and a decrease of $3.6 million compared to $368.0 million at December 31, 2012. During the third quarter of 2012, we recorded $88.7 million of goodwill and other intangible assets associated with the acquisition of Indiana Community Bancorp, of which $86.0 million is included in the “Community Banking” column and $2.7 million is included in the “Other” column for segment reporting. During the second quarter of 2013, Old National recorded $0.6 million of goodwill primarily related to the final pension settlement associated with Indiana Community Bancorp. This was allocated to the “Community Banking” segment. The decrease from December 31, 2012 is primarily attributable to amortization expense associated with other intangible assets.

Assets Held for Sale

Assets held for sale were $9.3 million at June 30, 2013 compared to $15.0 million at December 31, 2012. Included in assets held for sale are two financial centers associated with the Indiana Community Bancorp acquisition and four facilities associated with the Monroe Bancorp acquisition. The decrease is due to the branch sales that occurred in the first quarter of 2013.

Other Assets

Other assets have increased $27.8 million, or 12.6%, since June 30, 2012 primarily a result of an increase in deferred tax assets, which was partially offset by fluctuations in the fair value of derivative financial instruments.

Funding

Total funding, comprised of deposits and wholesale borrowings, was $8.255 billion at June 30, 2013, an increase of 13.2% from $7.290 billion at June 30, 2012, and an increase of 1.8% from $8.106 billion at December 31, 2012. Included in total funding were deposits of $6.840 billion at June 30, 2013, an increase of $169.8 million, or 2.5%, compared to June 30, 2012, and a decrease of $438.9 million, or 6.0%, compared to December 31, 2012. The decrease from December 31, 2012 is partially attributable to the $150.1 million of deposits that were sold in conjunction with our branch sale in the first quarter of 2013. Included in total deposits at June 30, 2013 are $562.2 million from the acquisition of Indiana Community Bancorp. Noninterest-bearing deposits increased 1.8%, or $33.5 million, compared to June 30, 2012. Savings deposits increased 12.9%, or $216.4 million. NOW deposits increased 3.1% or $49.1 million, while money market deposits increased 0.2%, or $0.6 million, compared to June 30, 2012. Time deposits decreased 10.4% or $129.8 million compared to June 30, 2012. Year over year we experienced an increase in noninterest-bearing demand deposits.

72

We use wholesale funding to augment deposit funding and to help maintain our desired interest rate risk position. At June 30, 2013, wholesale borrowings, including short-term borrowings and other borrowings, increased $795.0 million, or 128.3%, from June 30, 2012 and increased $587.4 million, or 71.0%, from December 31, 2012, respectively. Included in wholesale funding at June 30, 2013 is $17.6 million from the acquisition of Indiana Community Bancorp. Wholesale funding as a percentage of total funding was 17.1% at June 30, 2013, compared to 8.5% at June 30, 2012, and 10.2% at December 31, 2012. Short-term borrowings have increased $184.4 million since June 30, 2012 while other borrowings have increased $610.6 million since June 30, 2012. The increase in wholesale funding was in anticipation of the pending branch acquisition from Bank of America. The deposit funding assumed in the transaction replaced the majority of the increase in short-term and other borrowings. Over the past year, we have reduced the cost of other borrowings by changing the composition of other borrowings. During the first six months of 2013, we terminated $50.0 million of FHLB advances and restructured $33.4 million of FHLB advances. During the fourth quarter of 2012, we terminated $50.0 million of FHLB advances. On June 30, 2012 we redeemed $13.0 million of subordinated notes and $3.0 million of trust preferred securities. Much of the increase in other borrowings during the first six months of 2013 has involved FHLB advances with short maturities.

Accrued Expenses and Other Liabilities

Accrued expenses and other liabilities decreased $106.6 million, or 32.7%, since June 30, 2012 primarily as a result of a decrease in payables associated with securities trades that did not settle until early July 2012 and the timing of the payments combined with fluctuations in the fair value of derivative financial instruments.

Capital

Shareholders’ equity totaled $1.167 billion at June 30, 2013, compared to $1.074 billion at June 30, 2012, and $1.195 billion at December 31, 2012. The June 30, 2013 and December 31, 2012 balances include approximately $88.5 million from the approximately 6.6 million shares of common stock that were issued in conjunction with the acquisition of Indiana Community Bancorp.

We paid cash dividends of $0.10 and $0.20 per share for the three and six months ended June 30, 2013, which reduced equity by $20.2 million. We paid cash dividends of $0.09 and $0.18 per share for the three and six months ended June 30, 2012, which reduced equity by $17.0 million. We repurchased shares of our stock, reducing shareholders’ equity by $7.7 million during the six months ended June 30, 2013, and $0.7 million during the six months ended June 30, 2012. During the second quarter of 2013, we repurchased 500,000 shares of our common stock under our buyback program. The remaining repurchases related primarily to our employee stock based compensation plans. The change in unrealized losses on investment securities decreased equity by $56.0 million during the six months ended June 30, 2013, and increased equity by $6.3 million during the six months ended June 30, 2012. Shares issued for reinvested dividends, stock options, restricted stock and stock compensation plans increased shareholders’ equity by $2.7 million during the six months ended June 30, 2013, compared to $1.6 million during the six months ended June 30, 2012.

Capital Adequacy

Old National and the banking industry are subject to various regulatory capital requirements administered by the federal banking agencies. At June 30, 2013, Old National and its bank subsidiary exceeded the regulatory minimums and Old National Bank met the regulatory definition of well-capitalized based on the most recent regulatory definition. To be categorized as well-capitalized, the bank subsidiary must maintain at least a total risk-based capital ratio of 10.0%, a Tier 1 risk-based capital ratio of 6.0% and a Tier 1 leverage ratio of 5.0%. Goodwill of $86.2 million, core deposit intangibles of $1.3 million and customer relationship intangibles of $1.7 million were recorded in conjunction with the Indiana Community Bancorp acquisition. Such goodwill and intangibles are excluded from regulatory capital as calculated under regulatory accounting practices.

73

As of June 30, 2013, Old National’s consolidated capital position remains strong as evidenced by the following comparisons of key industry ratios.

	Regulatory Guidelines			June 30,						December 31,
	Minimum			2013			2012			2012

RISK MANAGEMENT

Overview

Management, with the oversight of the Board of Directors through its Risk and Credit Policy Committee and its Funds Management Committee, has in place company-wide structures, processes, and controls for managing and mitigating risk. The following discussion addresses the three major risks that we face: credit, market, and liquidity.

Credit Risk

Credit risk represents the risk of loss arising from an obligor’s inability or failure to meet contractual payment or performance terms. Our primary credit risks result from our investment and lending activities.

Investment Activities

Within our securities portfolio, the non-agency collateralized mortgage obligations represent one of our greatest exposures to the current instability in the residential real estate and credit markets. At June 30, 2013, we had four non-agency collateralized mortgage obligations with a fair value of $20.4 million or approximately 0.77% of the available-for-sale securities portfolio. Three of these securities were rated below investment grade. The net unrealized gain on these securities at June 30, 2013, was approximately $0.8 million.

While the overall residential real estate market has stabilized, we expect conditions to remain uncertain for the foreseeable future. Deterioration in the performance of the underlying loan collateral could result in deterioration in the performance of our asset-backed securities. As detailed above, three non-agency mortgage-backed securities were rated below investment grade as of June 30, 2013. During the first six months of 2013, one non-agency mortgage-backed security that was below investment grade paid down and two non-agency mortgage-backed securities were sold. There was no other-than-temporary-impairment recorded in the first six months of 2013 on these securities. During the first six months of 2012, we experienced $0.7 million of other-than-temporary-impairment losses on five of these securities, which was recorded as a credit loss in earnings.

74

We also carry a higher exposure to loss in our pooled trust preferred securities, which are collateralized debt obligations, due to illiquidity in that market and the performance of the underlying collateral. At June 30, 2013, we had pooled trust preferred securities with a fair value of approximately $9.2 million, or 0.34% of the available-for-sale securities portfolio. During the first six months of 2013, we experienced no other-than-temporary-impairment losses on these securities. These securities remained classified as available-for-sale and at June 30, 2013, the unrealized loss on our pooled trust preferred securities was approximately $13.9 million. Unrealized losses related to our holdings of pooled trust preferred securities have remained for the longest continuous period of time. During the first six months of 2012, we experienced $0.2 million of other-than-temporary-impairment losses on one of theses securities, which was recorded as a credit loss in earnings.

The remaining mortgage-backed securities are backed by U.S. government-sponsored or federal agencies. Municipal bonds, corporate bonds and other debt securities are evaluated by reviewing the credit-worthiness of the issuer and general market conditions. We do not have the intent to sell these securities and it is likely that we will not be required to sell these securities before their anticipated recovery.

Included in the held-to-maturity category at June 30, 2013 are approximately $44.3 million of agency mortgage-backed securities and $184.5 million of municipal securities at amortized cost.

Counterparty Exposure

Counterparty exposure is the risk that the other party in a financial transaction will not fulfill its obligation in a financial transaction. We define counterparty exposure as nonperformance risk in transactions involving federal funds sold and purchased, repurchase agreements, correspondent bank relationships, and derivative contracts with companies in the financial services industry. Old National’s net counterparty exposure was an asset of $284.9 million at June 30, 2013.

Lending Activities

Commercial

Commercial and industrial loans are made primarily for the purpose of financing equipment acquisition, expansion, working capital, and other general business purposes. Lease financing consists of direct financing leases and are used by commercial customers to finance capital purchases ranging from computer equipment to transportation equipment. The credit decisions for these transactions are based upon an assessment of the overall financial capacity of the applicant. A determination is made as to the applicant’s ability to repay in accordance with the proposed terms as well as an overall assessment of the risks involved. In addition to an evaluation of the applicant’s financial condition, a determination is made of the probable adequacy of the primary and secondary sources of repayment, such as additional collateral or personal guarantees, to be relied upon in the transaction. Credit agency reports of the applicant’s credit history supplement the analysis of the applicant’s creditworthiness.

Commercial mortgages and construction loans are offered to real estate investors, developers, and builders primarily domiciled in the geographic market areas we serve, primarily Indiana, Illinois and Kentucky. These loans are secured by first mortgages on real estate at loan-to-value (“LTV”) margins deemed appropriate for the property type, quality, location and sponsorship. Generally, these LTV ratios do not exceed 80%. The commercial properties are predominantly non-residential properties such as retail centers, apartments, industrial properties and, to a lesser extent, more specialized properties. Substantially all of our commercial real estate loans are secured by properties located in our primary market area.

In the underwriting of our commercial real estate loans, we obtain appraisals for the underlying properties. Decisions to lend are based on the economic viability of the property and the creditworthiness of the borrower. In evaluating a proposed commercial real estate loan, we primarily emphasize the ratio of the property’s projected net cash flows to the loan’s debt service requirement. The debt service coverage ratio normally is not less than 120% and it is computed after deduction for a vacancy factor and property expenses as appropriate. In addition, a personal guarantee of the loan or a portion thereof is often required from the principal(s) of the borrower. We require title insurance insuring the priority of our lien, fire, and extended coverage casualty insurance, and flood insurance, if appropriate, in order to protect our security interest in the underlying property. In addition, business interruption insurance or other insurance may be required.

75

Construction loans are underwritten against projected cash flows derived from rental income, business income from an owner-occupant or the sale of the property to an end-user. We may mitigate the risks associated with these types of loans by requiring fixed-price construction contracts, performance and payment bonding, controlled disbursements, and pre-sale contracts or pre-lease agreements.

Consumer

We offer a variety of first mortgage and junior lien loans to consumers within our markets, with residential home mortgages comprising our largest consumer loan category. These loans are secured by a primary residence and are underwritten using traditional underwriting systems to assess the credit risks of the consumer. Decisions are primarily based on LTV ratios, debt-to-income (“DTI”) ratios, liquidity and credit scores. A maximum LTV ratio of 80% is generally required, although higher levels are permitted with mortgage insurance or other mitigating factors. We offer fixed rate mortgages and variable rate mortgages with interest rates that are subject to change every year after the first, third, fifth, or seventh year, depending on the product and are based on fully-indexed rates such as the London Interbank Offered Rate (“LIBOR”). We do not offer interest-only loans, payment-option facilities, sub-prime loans, or any product with negative amortization.

Home equity loans are secured primarily by second mortgages on residential property of the borrower. The underwriting terms for the home equity product generally permits borrowing availability, in the aggregate, up to 90% of the appraised value of the collateral property at the time of origination. We offer fixed and variable rate home equity loans, with variable rate loans underwritten at fully-indexed rates. Decisions are primarily based on LTV ratios, DTI ratios, liquidity, and credit scores. We do not offer home equity loan products with reduced documentation.

Automobile loans include loans and leases secured by new or used automobiles. We originate automobile loans and leases primarily on an indirect basis through selected dealerships. We require borrowers to maintain collision insurance on automobiles securing consumer loans, with us listed as loss payee. Our procedures for underwriting automobile loans include an assessment of an applicant’s overall financial capacity, including credit history and the ability to meet existing obligations and payments on the proposed loan. Although an applicant’s creditworthiness is the primary consideration, the underwriting process also includes a comparison of the value of the collateral security to the proposed loan amount.

Asset Quality

Community-based lending personnel, along with region-based independent underwriting and analytic support staff, extend credit under guidelines established and administered by our Risk and Credit Policy Committee. This committee, which meets quarterly, is made up of outside directors. The committee monitors credit quality through its review of information such as delinquencies, credit exposures, peer comparisons, problem loans and charge-offs. In addition, the committee reviews and approves recommended loan policy changes to assure it remains appropriate for the current lending environment.

We lend primarily to small- and medium-sized commercial and commercial real estate clients in various industries including manufacturing, agribusiness, transportation, mining, wholesaling and retailing. At June 30, 2013, we had no concentration of loans in any single industry exceeding 10% of our portfolio and had no exposure to foreign borrowers or sovereign debt. Our policy is to concentrate our lending activity in the geographic market areas we serve, primarily Indiana, Illinois and Kentucky. We continue to be affected by weakness in the economy of our principal markets. Management expects that trends in under-performing, criticized and classified loans will be influenced by the degree to which the economy strengthens or weakens.

76

During the third quarter of 2011, Old National acquired the banking operations of Integra Bank in an FDIC assisted transaction. As of June 30, 2013, acquired loans totaled $329.4 million and there was $23.1 million of other real estate owned. The Company entered into separate loss sharing agreements with the FDIC providing for specified credit loss protection for substantially all acquired single family residential loans, commercial loans, and other real estate owned. In accordance with accounting for business combinations, there was no allowance brought forward on any of the acquired loans, as the credit losses evident in the loans were included in the determination of the fair value of the loans at the acquisition date. At June 30, 2013, approximately $283.1 million of loans, net of allowance, and $23.1 million of other real estate owned are covered by the loss sharing agreements. Under the terms of the loss sharing agreements, the FDIC will reimburse Old National for 80% of losses up to $275.0 million. These covered assets are included in our summary of under-performing, criticized and classified assets found below.

On September 15, 2012, Old National closed on its acquisition of Indiana Community Bancorp (“IBT”). As of June 30, 2013, acquired loans totaled $335.3 million and there was $1.8 million of other real estate owned. In accordance with accounting for business combinations, there was no allowance brought forward on any of the acquired loans, as the credit losses evident in the loans were included in the determination of the fair value of the loans at the acquisition date. Old National reviewed the acquired loans and determined that as of June 30, 2013, $3.9 million met the definition of criticized, $15.2 million were considered classified, and $41.0 million were doubtful. Our current preference would be to work these loans and avoid foreclosure actions unless additional credit deterioration becomes apparent. These assets are included in our summary of under-performing, criticized and classified assets found below.

(1) Loans exclude residential loans held for sale and leases held for sale.

(2) Non-performing loans include nonaccrual and renegotiated loans.

(3) Includes 5 pooled trust preferred securities, 3 non-agency mortgage-backed securities and 4 corporate securities at June 30, 2013.

(4) Because the acquired loans from Monroe, Integra and Indiana Community were recorded at fair value in accordance with ASC 805 at the date of acquisition, the credit risk is incorporated in the fair value recorded. No allowance for loan losses is recorded on the acquisition date.

(5) The Company entered into separate loss sharing agreements with the FDIC providing for specified credit loss protection for substantially all acquired single family residential loans, commercial loans and other real estate owned. At June 30, 2013, we expect eighty percent of any losses incurred on these covered assets to be reimbursed to Old National by the FDIC.

(6) Includes approximately $80.8 million of purchased credit impaired loans that are categorized as nonaccrual because the collection of principal or interest is doubtful. These loans are accounted for under FASB ASC 310-30 and accordingly treated as performing assets.

Under-performing assets totaled $230.9 million at June 30, 2013, a decrease of $44.6 million compared to $275.5 million at June 30, 2012, and a decrease of $71.0 million compared to $301.9 million at December 31, 2012. As a percent of total loans and other real estate owned, under-performing assets, at June 30, 2013, were 4.43%, a decrease from the June 30, 2012 ratio of 5.80% and a decrease from the December 31, 2012 ratio of 5.77%. At June 30, 2013, under-performing assets related to covered assets acquired in the Integra Bank acquisition were approximately $83.5 million, which included approximately $60.3 million of nonaccrual loans, $0.1 million of past due loans and renegotiated loans and $23.1 million of other real estate owned. The nonaccrual covered loans are categorized in this manner because the collection of principal or interest is doubtful. However, they are accounted for under FASB ASC 310-30 and accordingly treated as performing assets. At June 30, 2013, under-performing assets related to Indiana Community Bancorp were approximately $42.9 million, which included approximately $41.0 million of nonaccrual loans and $1.9 million of other real estate owned.

Nonaccrual loans were $189.8 million at June 30, 2013, compared to $240.5 million at June 30, 2012, and $254.3 million at December 31, 2012. Nonaccrual loans decreased primarily as a result of a decrease in our acquired covered nonaccrual loans. Nonaccrual loans, however, have remained at elevated levels since the Monroe and the FDIC-assisted acquisition of Integra in 2011. In addition, nonaccrual loans at June 30, 2013 include $41.0 million of loans related to loans acquired from Indiana Community Bancorp in September 2012. Because the acquired loans from Monroe Bancorp, Integra Bank and Indiana Community Bancorp were recorded at fair value in accordance with ASC 805 at the date of acquisition, the credit risk is incorporated in the fair value recorded. No allowance for loan losses is recorded on the acquisition date. As a percent of nonaccrual loans (excluding covered loans), the allowance for loan losses was 33.90% at June 30, 2013, compared to 50.70% at June 30, 2012 and 32.61% at December 31, 2012. Included in nonaccrual loans at June 30, 2013 and December 31, 2012 were $80.8 million and $156.8 million, respectively, of purchased credit impaired loans that were included in the nonaccrual category because the collection of principal or interest is doubtful. However, they are accounted for under FASB ASC 310-30 and accordingly treated as performing assets. We would expect our nonaccrual loans to remain at elevated levels until management can work through and resolve these purchased credit impaired loans.

Total classified and criticized assets were $482.4 million at June 30, 2013, a decrease of $50.3 million from June 30, 2012, and a decrease of $54.8 million from December 31, 2012. Included in criticized and classified assets at June 30, 2013, is $60.0 million related to the acquisition of Indiana Community Bancorp. Other classified assets include $49.6 million, $102.4 million and $59.2 million of investment securities that fell below investment grade rating at June 30, 2013, June 30, 2012 and December 31, 2012, respectively.

Old National may choose to restructure the contractual terms of certain loans. The decision to restructure a loan, versus aggressively enforcing the collection of the loan, may benefit Old National by increasing the ultimate probability of collection.

Any loans that are modified are reviewed by Old National to identify if a troubled debt restructuring (“TDR”) has occurred, which is when for economic or legal reasons related to a borrower’s financial difficulties, the Bank grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. During the six months ended June 30, 2013, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date at a stated rate of interest lower than the current market rate of new debt with similar risk, or a permanent reduction of the recorded investment of the loan.

Loans modified in a troubled debt restructuring are typically placed on nonaccrual status until the Company determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrate a period of performance according to the restructured terms for six months.

If the Company is unable to resolve a nonperforming loan issue the credit will be charged off when it is apparent there will be a loss. For large commercial type loans, each relationship is individually analyzed for evidence of apparent loss based on quantitative benchmarks or subjectively based upon certain events or particular circumstances. It is Old National’s policy to charge off small commercial loans scored through our small business credit center with contractual balances under $250,000 that have been placed on nonaccrual status or became ninety days or more delinquent, without regard to the collateral position. For residential and consumer loans, a charge off is recorded at the time foreclosure is initiated or when the loan becomes 120 to 180 days past due, whichever is earlier.

79

For commercial and industrial troubled debt restructurings, an allocated reserve is established within the allowance for loan losses for the difference between the carrying value of the loan and its computed fair value. To determine the fair value of the loan, one of the following methods is selected: (1) the present value of expected cash flows discounted at the loan’s original effective interest rate, (2) the loan’s observable market price, or (3) the fair value of the collateral value, if the loan is collateral dependent. The allocated reserve is established as the difference between the carrying value of the loan and the collectable value. If there are significant changes in the amount or timing of the loan’s expected future cash flows, impairment is recalculated and the valuation allowance is adjusted accordingly.

For consumer and residential troubled debt restructurings, an additional amount is added to the loan loss reserve that represents the difference in the present value of the cash flows between the original terms and the new terms of the modified loan, using the original effective interest rate of the loan as a discount rate.

At June 30, 2013, our troubled debt restructurings consisted of $11.4 million of commercial loans, $19.2 million of commercial real estate loans, $0.8 million of consumer loans and $0.7 million of residential loans, totaling $32.1 million. Approximately $21.5 million of the troubled debt restructuring at June 30, 2013 were included with nonaccrual loans. As of June 30, 2013, Old National had allocated specific reserves of $2.4 million to commercial loans and $1.5 million to commercial real estate loans for loans that have been modified in troubled debt restructurings. At December 31, 2012, our troubled debt restructurings consisted of $12.7 million of commercial loans, $18.4 million of commercial real estate loans, $0.5 million of consumer loans and $0.5 million of residential loans, totaling $32.1 million. Approximately $22.1 million of the troubled debt restructuring at December 31, 2012 were included with nonaccrual loans. As of December 31, 2012, Old National had allocated specific reserves of $3.7 million to commercial loans and $0.8 million to commercial real estate loans for loans that have been modified in troubled debt restructurings.

The terms of certain other loans were modified during the six months ended June 30, 2013 that did not meet the definition of a troubled debt restructuring. It is our process to review all classified and criticized loans that, during the period, have been renewed, have entered into a forbearance agreement, have gone from principal and interest to interest only, or have extended the maturity date. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on its debt in the foreseeable future without the modification. The evaluation is performed under the Company’s internal underwriting policy. We also evaluate whether a concession has been granted or if we were adequately compensated through a market interest rate, additional collateral or a bona fide guarantee. We also consider whether the modification was insignificant relative to the other terms of the agreement or if the delay in a payment was 90 days or less.

Purchased credit impaired (“PCI”) loans are not considered impaired until after the point at which there has been a degradation of cash flows below our expected cash flows at acquisition. If a PCI loan is subsequently modified, and meets the definition of a TDR, it will be removed from PCI accounting and accounted for as a TDR only if the PCI loan was being accounted for individually. If the purchased credit impaired loan is being accounted for as part of a pool, it will not be removed from the pool. As of June 30, 2013, it has not been necessary to remove any loans from PCI accounting.

In general, once a modified loan is considered a TDR, the loan will always be considered a TDR, and therefore impaired, until it is paid in full, otherwise settled, sold or charged off. However, our policy also permits for loans to be removed from troubled debt restructuring status in the years following the restructuring if the following two conditions are met: (1) The restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk, and (2) the loan is not impaired based on the terms specified by the restructuring agreement.

Allowance for Loan Losses and Reserve for Unfunded Commitments

Loan charge-offs, net of recoveries, totaled $0.5 million for the three months ended June 30, 2013, as compared to $1.5 million for the three months ended June 30, 2012. Loan charge-offs, net of recoveries, totaled $2.6 million for the six months ended June 30, 2013, as compared to $5.7 million for the six months ended June 30, 2012. Annualized, net charge-offs to average loans were 0.04% and 0.10% for the three and six months ended June 30, 2013, as compared to 0.13% and 0.24% for the three and six months ended June 30, 2012. Management will continue its efforts to reduce the level of non-performing loans and may consider the possibility of sales of troubled and non-performing loans, which could result in additional charge-offs to the allowance for loan losses.

To provide for the risk of loss inherent in extending credit, we maintain an allowance for loan losses. The determination of the allowance is based upon the size and current risk characteristics of the loan portfolio and includes an assessment of individual problem loans, actual loss experience, current economic events and regulatory guidance. At June 30, 2013, the allowance for loan losses was $49.3 million, a decrease of $5.5 million compared to $54.8 million at June 30, 2012, and a decrease of $5.5 million compared to $54.8 million at December 31, 2012. Impacting the allowance for loan losses and provision expense in 2013 are the following factors: (1) the loss factors applied to our performing loan portfolio have decreased over time as charge-offs were substantially lower, (2) the continuing trend in improved credit quality, and (3) the percentage of our legacy loan portfolio consisting of those loans where higher loss factors are applied (commercial and commercial real estate loans) is increasing at a slower pace than the percentage of our loan portfolio consisting of those loans where lower loss factors are applied (residential loans). As a percentage of total loans excluding loans held for sale, the allowance was 0.95% at June 30, 2013, compared to 1.16% at June 30, 2012, and 1.05% at December 31, 2012. The decrease from June 30, 2012 is a result of the $3.6 million of provision expense recapture during the second quarter of 2013 combined with the effect of the loans acquired from Indiana Community Bancorp during the third quarter of 2012. Because the acquired loans were recorded at fair value in accordance with ASC 805 at the date of acquisition, the credit risk is incorporated in the fair value recorded. No allowance for loan losses was recorded on the acquisition date. The provision for loan losses for the six months ended June 30, 2013, was a credit of $2.8 million compared to $2.4 million of expense for the six months ended June 30, 2012.

Because the acquired loans from Monroe Bancorp, Integra Bank and Indiana Community Bancorp were recorded at fair value in accordance with ASC 805 at the date of acquisition, the credit risk is incorporated in the fair value recorded. No allowance for loan losses is recorded on the acquisition date. We would expect that as the fair value mark is accreted into income over future periods, a reserve will be established to absorb credit deterioration or adverse changes in expected cash flows. Through June 30, 2013, $3.4 million and $5.5 million had been reserved for these purchased credits from Monroe Bancorp and Integra Bank, respectively.

The following table provides additional details of the following components of the allowance for loan losses, including FAS 5/ASC 450 (Accounting for Contingencies), FAS 114/ASC 310-40 (Accounting by Creditors for Impairment of a Loan) and SOP 03-3/ASC 310-30 (Accounting for Certain Loans or Debt Securities Acquired in a Transfer):

We maintain an allowance for losses on unfunded commercial lending commitments and letters of credit to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for loan losses, modified to take into account the probability of a drawdown on the commitment. The $2.4 million reserve for unfunded loan commitments at June 30, 2013 is classified as a liability account on the balance sheet. The reserve for unfunded loan commitments was $4.0 million at December 31, 2012. The decrease is the result of lower loss rates and improved asset quality.

Market Risk

Market risk is the risk that the estimated fair value of our assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that our net income will be significantly reduced by interest rate changes.

The objective of our interest rate management process is to maximize net interest income while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.

Potential cash flows, sales, or replacement value of many of our assets and liabilities, especially those that earn or pay interest, are sensitive to changes in the general level of interest rates. This interest rate risk arises primarily from our normal business activities of gathering deposits and extending loans. Many factors affect our exposure to changes in interest rates, such as general economic and financial conditions, customer preferences, historical pricing relationships, and re-pricing characteristics of financial instruments. Our earnings can also be affected by the monetary and fiscal policies of the U.S. Government and its agencies, particularly the Federal Reserve Board.

In managing interest rate risk, we, through the Funds Management Committee, a committee of the Board of Directors, establish guidelines, for asset and liability management, including measurement of short and long-term sensitivities to changes in interest rates. Based on the results of our analysis, we may use different techniques to manage changing trends in interest rates including:

• adjusting balance sheet mix or altering interest rate characteristics of assets and liabilities;

• changing product pricing strategies;

• modifying characteristics of the investment securities portfolio; or

• using derivative financial instruments, to a limited degree.

A key element in our ongoing process is to measure and monitor interest rate risk using a Net Interest Income at Risk simulation to model the interest rate sensitivity of the balance sheet and to quantify the impact of changing interest rates on the Company. The model quantifies the effects of various possible interest rate scenarios on projected net interest income over a one-year and a two-year cumulative horizon. The model assumes a semi-static balance sheet and measures the impact on net interest income relative to a base case scenario of hypothetical changes in interest rates over 24 months. The scenarios include prepayment assumptions, changes in the level of interest rates, the shape of the yield curve, and spreads between market interest rates in order to capture the impact from re-pricing, yield curve, option, and basis risks.

Our simulation scenarios assume the following market interest rates with an instantaneous shift from current interest rates.

A key element in the measurement and modeling of interest rate risk are the re-pricing assumptions of our transaction deposit accounts, which have no contractual maturity dates. We assume this deposit base is comprised of both core and more volatile balances and consists of both non-interest bearing and interest bearing accounts. Core deposit balances are assumed to be less interest rate sensitive and provide longer term funding. Volatile balances are assumed to be more interest rate sensitive and shorter in term. As part of our semi-static balance sheet modeling, we assume interest rates paid on the volatile deposits move in conjunction with changes in interest rates, in order to retain these deposits. This may include current non-interest bearing accounts.

Results of our simulation modeling project that our net interest income could change as follows over one-year and two-year horizons, relative to our base case scenarios at June 30th.

From June 30, 2012 to June 30, 2013, our results were primarily impacted by three factors. First, on September 15, 2012, we acquired Indiana Community Bank, which changed the mix of our balance sheet. Secondly, in early 2013, management made the strategic decision to increase short-term borrowings to fund additional purchases in the investment portfolio in anticipation of the purchase of 24 branches of Bank of America which closed on July 12, 2013. Finally, since early May 2013 interest rates have increased dramatically causing a steepening of the yield curve.

At June 30, 2013, our simulated exposure to an increase in interest rates shows that an immediate increase in rates of 1.00% will decrease our net interest income by $7.7 million (-2.89%) over a one year horizon compared to our base case scenario. Rate increases of 2.00% and 3.00% would cause net interest income to decline by $22.6 million (-8.50%) and $37.3 million (-14.04%), respectively. Over a two-year horizon, the model reflects a decrease in net interest income of $4.9 million (-0.92%) over base case, for the up 1.00%. For the up 2.00% scenario, net interest income decreases by $27.3 million (-5.18%) and, in an up 3.00% scenario, net interest income decreases $52.6 million (-10.00%) compared to our base case scenario. As a result of the already low interest rate environment, we did not include a 1.00% falling scenario.

Our models indicate that, over a one-year time horizon, we would be slightly out of policy given a 2.00% parallel interest rate shock. This is primarily the result of management’s strategic decision to increase short-term borrowings in anticipation of the purchase of Bank of America branches. Since we use a semi-static balance sheet in our modeling, these borrowings are assumed to re-price instantaneously with the shock in rates. However, these borrowings were repaid in July 2013 when the Bank of America transaction closed. We anticipate that this will bring us back within policy guidelines in July 2013 as deposit re-pricing lags that of short-term borrowings.

In addition to reporting our interest rate sensitivity assuming an instantaneous shift in rates of 1.00%, 2.00% and 3.00% across the interest rate curve, we have included the following modeling scenarios; short-end flattening, long-end flattening, short-end steepening, and long-end steepening. The shape of the yield curve can have a significant impact on our net interest income as the above table illustrates. A long-end flattening of the yield curve means that rates on the short-end of the curve remain stationary while long-end rates decline by 1.00%. Our modeling projects in this scenario that our net interest income would decline by $11.8 million (-2.25%) over a two year horizon. This is caused by longer term assets re-pricing at lower rates, while pricing on deposits, which are more closely tied to short-term rates, remains static. By contrast, in a long-end steepening scenario, short-term rates remain constant while rates on the long-end increase by 1.00%. In this scenario, our net interest income is projected to increase by $8.4 million (1.59%) over a two year horizon, since assets re-price at higher rates while rates on our deposits remain constant. This long-end steepening scenario most closely resembles the recent movement in interest rates since early May 2013.

Old National also has longer term interest rate risk exposure, which may not be appropriately measured by Net Interest Income at Risk modeling. We use Economic Value of Equity (EVE) sensitivity analysis to evaluate the impact of long term cash flows on earnings and capital. EVE modeling involves discounting present values of all cash flows under different interest rate scenarios. The discounted present value of all cash flows represents our economic value of equity. The amount of base case economic value and its sensitivity to shifts in interest rates provide a measure of the longer term re-pricing and option risk in the balance sheet. EVE simulation results are shown below, relative to base case.

	Economic Value of Equity
	6/30/2013								6/30/2012
Immediate Change in the Level of Interest Rates	Economic Value of Equity (millions)		$ Change (millions)			% Change			Economic Value of Equity (millions)		$ Change (millions)		% Change

Yield Curve at 6/30		950		—			0.00	%		634		—		0.00	%
- 1.00%		NA		NA			NA			NA		NA		NA

At June 30, 2013, Old National’s Economic Value of Equity (“EVE”) scenarios indicate negative changes to EVE in the up 1.00%, 2.00%, and 3.00% scenarios. These changes in EVE modeling results were driven primarily by the mix of the balance sheet noted above and the increase in the general level of interest rates. Modeling results at June 30, 2013, indicate that we remain within our Company’s acceptable risk tolerance levels.

As we noted in our comments regarding net interest income above, we fully expect that our EVE modeling results for July will improve due to the closing of the Bank of America transaction on July 12, 2013.

Because the models are driven by expected behavior in various interest rate scenarios and many factors besides market interest rates affect our net interest income and value, we recognize that model outputs are not guarantees of actual results. For this reason, we model many different combinations of interest rates and balance sheet assumptions to understand its overall sensitivity to market interest rate changes.

We use derivatives, primarily interest rate swaps, as one method to manage interest rate risk in the ordinary course of business. We also provide derivatives to our commercial customers in connection with managing interest rate risk. Our derivatives had an estimated fair value gain of $5.5 million at June 30, 2013, compared to an estimated fair value gain of $6.5 million at December 31, 2012. In addition, the notional amount of derivatives increased by $93.5 million from December 31, 2012. In May 2013, we entered into a $100 million notional, cash flow swap in conjunction with a $100 million variable rate Home Loan Bank advance. This swap is effective in May 2014 and matures in May 2016. See Note 17 to the consolidated financial statements for further discussion of derivative financial instruments.

Liquidity Risk

Liquidity risk arises from the possibility that we may not be able to satisfy current or future financial commitments, or may become unduly reliant on alternative funding sources. The Funds Management Committee of the Board of Directors establishes liquidity risk guidelines and, along with the Balance Sheet Management Committee, monitors liquidity risk. The objective of liquidity management is to ensure we have the ability to fund balance sheet growth and meet deposit and debt obligations in a timely and cost-effective manner. Management monitors liquidity through a regular review of asset and liability maturities, funding sources, and loan and deposit forecasts. We maintain strategic and contingency liquidity plans to ensure sufficient available funding to satisfy requirements for balance sheet growth, properly manage capital markets’ funding sources and to address unexpected liquidity requirements.

Loan repayments and maturing investment securities are a relatively predictable source of funds. However, deposit flows, calls of investment securities and prepayments of loans and mortgage-related securities are strongly influenced by interest rates, the housing market, general and local economic conditions, and competition in the marketplace. We continually monitor marketplace trends to identify patterns that might improve the predictability of the timing of deposit flows or asset prepayments.

Our ability to acquire funding at competitive prices is influenced by rating agencies’ views of our credit quality, liquidity, capital and earnings. All of the rating agencies place us in an investment grade that indicates a low risk of default. For both Old National and Old National Bank:

• Fitch Rating Service affirmed and withdrew its long-term and short-term ratings for both Old National Bancorp and Old National Bank on January 18, 2013, citing that ONB’s ratings are no longer relevant to Fitch’s rating coverage.

• Dominion Bond Rating Services has confirmed a stable outlook as of October 12, 2012.

• Moody’s Investor Service downgraded Old National Bank’s Long Term Rating from A1 to A2 and changed its outlook from Negative to Stable on November 1, 2011. Old National Bank’s Short Term Rating was unchanged.

The senior debt ratings of Old National and Old National Bank at June 30, 2013, are shown in the following table.

The Parent Company (Old National) has routine funding requirements consisting primarily of operating expenses, dividends to shareholders, debt service, net derivative cash flows and funds used for acquisitions. The Parent Company can obtain funding to meet its obligations from dividends and management fees collected from its subsidiaries, operating line of credit and through the issuance of debt securities. Additionally, the Parent Company has a shelf registration in place with the Securities and Exchange Commission permitting ready access to the public debt and equity markets. At June 30, 2013, the Parent Company’s other borrowings outstanding were $28.0 million, an increase of $15.0 million from June 30, 2012. This increase was the result of the Parent Company adding $15.0 million of Indiana Community Bancorp’s trust preferred securities on September 15, 2012.

Federal banking laws regulate the amount of dividends that may be paid by banking subsidiaries without prior approval. Prior regulatory approval is required if dividends to be declared in any year would exceed net earnings of the current year plus retained net profits for the preceding two years. Prior regulatory approval to pay dividends was not required in 2012 and is not currently required.

OFF-BALANCE SHEET ARRANGEMENTS

Off-balance sheet arrangements include commitments to extend credit and financial guarantees. Commitments to extend credit and financial guarantees are used to meet the financial needs of our customers. Our banking affiliates have entered into various agreements to extend credit, including loan commitments of $1.237 billion and standby letters of credit of $71.5 million at June 30, 2013. At June 30, 2013, approximately $1.190 billion of the loan commitments had fixed rates and $47 million had floating rates, with the floating rates ranging from 0% to 26.25%. At December 31, 2012, loan commitments were $1.253 billion and standby letters of credit were $63.4 million. The term of these off-balance sheet arrangements is typically one year or less.

During the second quarter of 2007, we entered into a risk participation in an interest rate swap. The interest rate swap had a notional amount of $8.3 million at June 30, 2013.

(1) For the remaining six months of fiscal 2013.

(2) Our subordinated notes, certain trust preferred securities and certain Federal Home Loan Bank advances have fixed rates ranging from 0.16% to 8.34%. All of our other long-term debt is at Libor based variable rates at June 30, 2013. The projected variable interest assumes no increase in Libor rates from June 30, 2013.

(3) Amount expected to be contributed to the pension plans in 2013. Amounts for 2014 and beyond are unknown at this time.

We rent certain premises and equipment under operating leases. See Note 18 to the consolidated financial statements for additional information on long-term lease arrangements.

We are party to various derivative contracts as a means to manage the balance sheet and our related exposure to changes in interest rates, to manage our residential real estate loan origination and sale activity, and to provide derivative contracts to our clients. Since the derivative liabilities recorded on the balance sheet change frequently and do not represent the amounts that may ultimately be paid under these contracts, these liabilities are not included in the table of contractual obligations presented above. Further discussion of derivative instruments is included in Note 17 to the consolidated financial statements.

In the normal course of business, various legal actions and proceedings are pending against us and our affiliates which are incidental to the business in which they are engaged. Further discussion of contingent liabilities is included in Note 18 to the consolidated financial statements.

In addition, liabilities recorded under FASB ASC 740-10 (FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109) are not included in the table because the amount and timing of any cash payments cannot be reasonably estimated. Further discussion of income taxes and liabilities recorded under FASB ASC 740-10 is included in Note 16 to the consolidated financial statements.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our accounting policies are described in Note 1 to the consolidated financial statements included in this Annual Report on Form 10-K for the year ended December 31, 2012. Certain accounting policies require management to use significant judgment and estimates, which can have a material impact on the carrying value of certain assets and liabilities. We consider these policies to be critical accounting policies. The judgment and assumptions made are based upon historical experience or other factors that management believes to be reasonable under the circumstances. Because of the nature of the judgment and assumptions, actual results could differ from estimates, which could have a material affect on our financial condition and results of operations.

The following accounting policies materially affect our reported earnings and financial condition and require significant judgments and estimates. Management has reviewed these critical accounting estimates and related disclosures with the Audit Committee of our Board.

88

Goodwill and Intangibles

• Description. For acquisitions, we are required to record the assets acquired, including identified intangible assets, and the liabilities assumed at their fair value. These often involve estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective. Under FASB ASC 350 (SFAS No. 142 Goodwill and Other Intangible Assets), goodwill and indefinite-lived assets recorded must be reviewed for impairment on an annual basis, as well as on an interim basis if events or changes indicate that the asset might be impaired. An impairment loss must be recognized for any excess of carrying value over fair value of the goodwill or the indefinite-lived intangible asset.

• Judgments and Uncertainties. The determination of fair values is based on internal valuations using management’s assumptions of future growth rates, future attrition, discount rates, multiples of earnings or other relevant factors.

• Effect if Actual Results Differ From Assumptions. Changes in these factors, as well as downturns in economic or business conditions, could have a significant adverse impact on the carrying values of goodwill or intangible assets and could result in impairment losses affecting the financials of the Company as a whole and the individual lines of business in which the goodwill or intangibles reside.

Acquired Impaired Loans

• Description. Loans acquired with evidence of credit deterioration since inception and for which it is probable that all contractual payments will not be received are accounted for under ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality (“ASC 310-30”). These loans are recorded at fair value at the time of acquisition, with no carryover of the related allowance for loan losses. Fair value of acquired loans is determined using a discounted cash flow methodology based on assumptions about the amount and timing of principal and interest payments, principal prepayments and principal defaults and losses, and current market rates. In recording the acquisition date fair values of acquired impaired loans, management calculates a non-accretable difference (the credit component of the purchased loans) and an accretable difference (the yield component of the purchased loans).

Over the life of the acquired loans, the Company continues to estimate cash flows expected to be collected on pools of loans sharing common risk characteristics, which are treated in the aggregate when applying various valuation techniques. The Company evaluates at each balance sheet date whether the present value of its pools of loans determined using the effective interest rates has decreased significantly and if so, recognizes a provision for loan loss in its consolidated statement of income. For any significant increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the pool’s remaining life.

• Judgments and Uncertainties. These cash flow evaluations are inherently subjective as they require management to make estimates about expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change.

• Effect if Actual Results Differ From Assumptions. Changes in these factors, as well as changing economic conditions will likely impact the carrying value of these acquired loans as well as the carrying value of any associated indemnification assets, as the FDIC will reimburse the Company for losses incurred on certain acquired loans, but the shared-loss agreements will not fully offset the financial effects of such a situation.

89

Allowance for Loan Losses

• Description. The allowance for loan losses is maintained at a level believed adequate by management to absorb probable incurred losses in the consolidated loan portfolio. Management’s evaluation of the adequacy of the allowance is an estimate based on reviews of individual loans, pools of homogeneous loans, assessments of the impact of current and anticipated economic conditions on the portfolio and historical loss experience. The allowance represents management’s best estimate, but significant downturns in circumstances relating to loan quality and economic conditions could result in a requirement for additional allowance. Likewise, an upturn in loan quality and improved economic conditions may allow a reduction in the required allowance. In either instance, unanticipated changes could have a significant impact on results of operations.

The allowance is increased through a provision charged to operating expense. Uncollectible loans are charged-off through the allowance. Recoveries of loans previously charged-off are added to the allowance. A loan is considered impaired when it is probable that contractual interest and principal payments will not be collected either for the amounts or by the dates as scheduled in the loan agreement. Our policy for recognizing income on impaired loans is to accrue interest unless a loan is placed on nonaccrual status. A loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectibility of principal or interest. We monitor the quality of our loan portfolio on an on-going basis and use a combination of detailed credit assessments by relationship managers and credit officers, historic loss trends, and economic and business environment factors in determining the allowance for loan losses. We record provisions for loan losses based on current loans outstanding, grade changes, mix of loans and expected losses. A detailed loan loss evaluation on an individual loan basis for our highest risk loans is performed quarterly. Management follows the progress of the economy and how it might affect our borrowers in both the near and the intermediate term. We have a formalized and disciplined independent loan review program to evaluate loan administration, credit quality and compliance with corporate loan standards. This program includes periodic reviews and regular reviews of problem loan reports, delinquencies and charge-offs.

• Judgments and Uncertainties. We use migration analysis as a tool to determine the adequacy of the allowance for loan losses for performing commercial loans. Migration analysis is a statistical technique that attempts to estimate probable losses for existing pools of loans by matching actual losses incurred on loans back to their origination. Judgment is used to select and weight the historical periods which are most representative of the current environment.

We calculate migration analysis using several different scenarios based on varying assumptions to evaluate the widest range of possible outcomes. The migration-derived historical commercial loan loss rates are applied to the current commercial loan pools to arrive at an estimate of probable losses for the loans existing at the time of analysis. The amounts determined by migration analysis are adjusted for management’s best estimate of the effects of current economic conditions, loan quality trends, results from internal and external review examinations, loan volume trends, credit concentrations and various other factors.

We use historic loss ratios adjusted for expectations of future economic conditions to determine the appropriate level of allowance for consumer and residential real estate loans.

• Effect if Actual Results Differ From Assumptions. The allowance represents management’s best estimate, but significant downturns in circumstances relating to loan quality and economic conditions could result in a requirement for additional allowance. Likewise, an upturn in loan quality and improved economic conditions may allow a reduction in the required allowance. In either instance, unanticipated changes could have a significant impact on results of operations.

90

Management’s analysis of probable losses in the portfolio at June 30, 2013, resulted in a range for allowance for loan losses of $10.6 million. The range pertains to general (FASB ASC 310, Receivables/SFAS 5) reserves for both retail and performing commercial loans. Specific (FASB ASC 310, Receivables/SFAS 114) reserves do not have a range of probable loss. Due to the risks and uncertainty associated with the economy, our projection of FAS 5 loss rates inherent in the portfolio, and our selection of representative historical periods, we establish a range of probable outcomes (a high-end estimate and a low-end estimate) and evaluate our position within this range. The potential effect to net income based on our position in the range relative to the high and low endpoints is a decrease of $2.0 million and an increase of $4.9 million, respectively, after taking into account the tax effects. These sensitivities are hypothetical and are not intended to represent actual results.

Derivative Financial Instruments

• Description. As part of our overall interest rate risk management, we use derivative instruments to reduce exposure to changes in interest rates and market prices for financial instruments. The application of the hedge accounting policy requires judgment in the assessment of hedge effectiveness, identification of similar hedged item groupings and measurement of changes in the fair value of derivative financial instruments and hedged items. To the extent hedging relationships are found to be effective, as determined by FASB ASC 815 (SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities), changes in fair value of the derivatives are offset by changes in the fair value of the related hedged item or recorded to other comprehensive income. Management believes hedge effectiveness is evaluated properly in preparation of the financial statements. All of the derivative financial instruments we use have an active market and indications of fair value can be readily obtained. We are not using the “short-cut” method of accounting for any fair value derivatives.

• Judgments and Uncertainties. The application of the hedge accounting policy requires judgment in the assessment of hedge effectiveness, identification of similar hedged item groupings and measurement of changes in the fair value of derivative financial instruments and hedged items.

• Effect if Actual Results Differ From Assumptions. To the extent hedging relationships are found to be effective, as determined by FASB ASC 815 (SFAS No. 133 Accounting for Derivative Instruments and Hedging Activities), changes in fair value of the derivatives are offset by changes in the fair value of the related hedged item or recorded to other comprehensive income. However, if in the future the derivative financial instruments used by us no longer qualify for hedge accounting treatment, all changes in fair value of the derivative would flow through the consolidated statements of income in other noninterest income, resulting in greater volatility in our earnings.

Income Taxes

• Description. We are subject to the income tax laws of the U.S., its states and the municipalities in which we operate. These tax laws are complex and subject to different interpretations by the taxpayer and the relevant government taxing authorities. We review income tax expense and the carrying value of deferred tax assets quarterly; and as new information becomes available, the balances are adjusted as appropriate. FASB ASC 740-10 (FIN 48) prescribes a recognition threshold of more-likely-than-not, and a measurement attribute for all tax positions taken or expected to be taken on a tax return, in order for those tax positions to be recognized in the financial statements. See Note 12 to the Consolidated Financial Statements for a further description of our provision and related income tax assets and liabilities.

• Judgments and Uncertainties. In establishing a provision for income tax expense, we must make judgments and interpretations about the application of these inherently complex tax laws. We must also make estimates about when in the future certain items will affect taxable income in the various tax jurisdictions. Disputes over interpretations of the tax laws may be subject to review/adjudication by the court systems of the various tax jurisdictions or may be settled with the taxing authority upon examination or audit.

91

• Effect if Actual Results Differ From Assumptions. Although management believes that the judgments and estimates used are reasonable, actual results could differ and we may be exposed to losses or gains that could be material. To the extent we prevail in matters for which reserves have been established, or are required to pay amounts in excess of our reserves, our effective income tax rate in a given financial statement period could be materially affected. An unfavorable tax settlement would result in an increase in our effective income tax rate in the period of resolution. A favorable tax settlement would result in a reduction in our effective income tax rate in the period of resolution.

Valuation of Securities

• Description. The fair value of our securities is determined with reference to price estimates. In the absence of observable market inputs related to items such as cash flow assumptions or adjustments to market rates, management judgment is used. Different judgments and assumptions used in pricing could result in different estimates of value.

When the fair value of a security is less than its amortized cost for an extended period, we consider whether there is an other-than-temporary-impairment in the value of the security. If, in management’s judgment, an other-than-temporary-impairment exists, the portion of the loss in value attributable to credit quality is transferred from accumulated other comprehensive loss as an immediate reduction of current earnings and the cost basis of the security is written down by this amount.

We consider the following factors when determining an other-than-temporary-impairment for a security or investment:

• The length of time and the extent to which the fair value has been less than amortized cost;

• The financial condition and near-term prospects of the issuer;

• The underlying fundamentals of the relevant market and the outlook for such market for the near future;

• Our intent to sell the debt security or whether it is more likely than not that we will be required to sell the debt security before its anticipated recovery; and

• When applicable for purchased beneficial interests, the estimated cash flows of the securities are assessed for adverse changes.

Quarterly, securities are evaluated for other-than-temporary-impairment in accordance with FASB ASC 320 (SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities), and FASB ASC 325-10 (Emerging Issues Task Force No. 99-20, Recognition of Interest Income and Impairment on Purchased and Retained Beneficial Interest in Securitized Financial Assets) and FASB ASC 320-10 (FSP No. FAS 115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments). An impairment that is an “other-than-temporary-impairment” is a decline in the fair value of an investment below its amortized cost attributable to factors that indicate the decline will not be recovered over the anticipated holding period of the investment. Other-than-temporary-impairments result in reducing the security’s carrying value by the amount of credit loss. The credit component of the other-than-temporary-impairment loss is realized through the statement of income and the remainder of the loss remains in other comprehensive income.

• Judgments and Uncertainties. The determination of other-than-temporary-impairment is a subjective process, and different judgments and assumptions could affect the timing and amount of loss realization. In addition, significant judgments are required in determining valuation and impairment, which include making assumptions regarding the estimated prepayments, loss assumptions and interest cash flows.

• Effect if Actual Results Differ From Assumptions. Actual credit deterioration could be more or less severe than estimated. Upon subsequent review, if cash flows have significantly improved, the discount would be amortized into earnings over the remaining life of the debt security in a prospective manner based on the amount and timing of future cash flows. Additional credit deterioration resulting in an adverse change in cash flows would result in additional other-than-temporary impairment loss recorded in the income statement.

FORWARD-LOOKING STATEMENTS

In this report, we have made various statements regarding current expectations or forecasts of future events, which speak only as of the date the statements are made. These statements are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are also made from time-to-time in press releases and in oral statements made by the officers of Old National Bancorp (“Old National,” or the “Company”). Forward-looking statements are identified by the words “expect,” “may,” “could,” “intend,” “project,” “estimate,” “believe”, “anticipate” and similar expressions. Forward-looking statements also include, but are not limited to, statements regarding estimated cost savings, plans and objectives for future operations, the Company’s business and growth strategies, including future acquisitions of banks, regulatory developments, and expectations about performance as well as economic and market conditions and trends.

Such forward-looking statements are based on assumptions and estimates, which although believed to be reasonable, may turn out to be incorrect. Therefore, undue reliance should not be placed upon these estimates and statements. We can not assure that any of these statements, estimates, or beliefs will be realized and actual results may differ from those contemplated in these “forward-looking statements.” We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events, or otherwise. You are advised to consult further disclosures we may make on related subjects in our filings with the SEC. In addition to other factors discussed in this report, some of the important factors that could cause actual results to differ materially from those discussed in the forward-looking statements include the following:

• economic, market, operational, liquidity, credit and interest rate risks associated with our business;

• economic conditions generally and in the financial services industry;

• expected cost savings in connection with the consolidation of recent acquisitions may not be fully realized or realized within the expected time frames, and deposit attrition, customer loss and revenue loss following completed acquisitions may be greater than expected;

• unexpected difficulties and losses related to FDIC-assisted acquisitions, including those resulting from our loss-sharing arrangements with the FDIC;

• failure to properly understand risk characteristics of newly entered markets;

• increased competition in the financial services industry either nationally or regionally, resulting in, among other things, credit quality deterioration;

• our ability to achieve loan and deposit growth;

• volatility and direction of market interest rates;

• governmental legislation and regulation, including changes in accounting regulation or standards;

• our ability to execute our business plan;

ITEM 4. CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Evaluation of disclosure controls and procedures. Old National’s principal executive officer and principal financial officer have concluded that Old National’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended), based on their evaluation of these controls and procedures as of the end of the period covered by this Form 10-Q, are effective at the reasonable assurance level as discussed below to ensure that information required to be disclosed by Old National in the reports it files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to Old National’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Limitations on the Effectiveness of Controls. Management, including the principal executive officer and principal financial officer, does not expect that Old National’s disclosure controls and internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be only reasonable assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, control may become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting. There were no changes in Old National’s internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, Old National’s internal control over financial reporting.

Acquisition and Divestiture Activity

NOTE 3 – ACQUISITION AND DIVESTITURE ACTIVITY

Indiana Community Bancorp

On September 15, 2012, Old National acquired 100% of Indiana Community Bancorp (“IBT”) in an all stock transaction. IBT was headquartered in Columbus, Indiana and had 17 full-service banking centers serving the South Central Indiana area. The acquisition increased Old National’s position as the third largest branch network in Indiana and allowed Old National to enter into the vibrant, growing region of south central Indiana in a rapid and cost effective manner. We also believe there are opportunities to enhance income and improve efficiencies. Pursuant to the merger agreement, the shareholders of IBT received approximately 6.6 million shares of Old National Bancorp stock valued at approximately $88.5 million.

Under the acquisition method of accounting, the total estimated purchase price is allocated to IBT’s net tangible and intangible assets based on their current estimated fair values on the date of the acquisition. Based on management’s preliminary valuation of the fair value of tangible and intangible assets acquired and liabilities assumed, which are based on assumptions that are subject to change, the purchase price for the IBT acquisition is allocated as follows (in thousands):

Cash and cash equivalents	$	78,540
Investment securities—available for sale		147,710
Federal Home Loan Bank stock, at cost		7,092
Loans		497,434
Premises and equipment		13,345
Accrued interest receivable		2,165
Other real estate owned		6,111
Company-owned life insurance		15,833
Other assets		49,655
Deposits		(784,589	)
Other borrowings		(15,464	)
Accrued expenses and other liabilities		(18,564	)
Net tangible assets acquired		(732	)
Definite-lived intangible assets acquired		3,024
Goodwill		86,205
Purchase price	$	88,497

Prior to the end of the one year measurement period for finalizing the purchase price allocation, if information becomes available which would indicate adjustments are required to the purchase price allocation, such adjustments will be included in the purchase price allocation retrospectively. During the fourth quarter of 2012, adjustments were made in the purchase price allocation that affected the amounts allocated to loans, other real estate owned, other assets, accrued expenses and other liabilities and goodwill. During the second quarter of 2013, adjustments were made in the purchase price allocation that affected the amounts allocated to premises and equipment, other assets, accrued expenses and other liabilities and goodwill.

Of the total purchase price, $0.7 million has been allocated to net tangible liabilities acquired and $3.0 million has been allocated to definite-lived intangible assets acquired. The remaining purchase price has been allocated to goodwill. The goodwill will not be deductible for tax purposes and is included in the “Community Banking” and “Other” segments, as described in Note 20 of these consolidated financial statement footnotes.

The components of the estimated fair value of the acquired identifiable intangible assets are in the table below. These intangible assets will be amortized on an accelerated basis over their estimated lives and are included in the “Community Banking” and “Other” segments, as described in Note 20 of these consolidated financial statement footnotes.

Divestiture

On August 16, 2012, Old National announced plans to sell the deposits of nine banking centers located in southern Illinois and western Kentucky. As such, these deposits were considered held for sale as of December 31, 2012. The deposits totaled approximately $150.0 million at December 31, 2012. Old National also announced plans to consolidate 19 banking centers into existing branch locations. The consolidations occurred during the fourth quarter of 2012 and the sales closed during the first quarter of 2013. Deposits at the time of sale were approximately $150.1 million and the Company received a deposit premium of $2.2 million on the sales during the first quarter of 2013.

Branch Acquisition

On January 9, 2013 Old National announced that it had entered into a purchase and assumption agreement to acquire 24 bank branches of Bank of America. Four of the branches are located in northern Indiana and 20 branches are located in southwest Michigan. Deposit and loan balances to be included in the transaction were approximately $575.0 million and $5.0 million, respectively, as of July 9, 2013. The Company paid a deposit premium of 2.94%. The acquisition has doubled Old National’s presence in the South Bend/Elkhart area and provided a logical market extension into southwest Michigan. The transaction closed on July 12, 2013.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

NOTE 17 – DERIVATIVE FINANCIAL INSTRUMENTS

As part of the Company’s overall interest rate risk management, Old National uses derivative instruments, including interest rate swaps, caps and floors. The notional amount of these derivative instruments was $141.0 million and $41.0 million at June 30, 2013 and December 31, 2012, respectively. The June 30, 2013 balances consist of $141.0 million notional amount of receive-fixed interest rate swaps on certain of its FHLB advances. The December 31, 2012 balances consist of $41.0 million notional amount of receive-fixed interest rate swaps on certain of its FHLB advances. These hedges were entered into to manage both interest rate risk and asset sensitivity on the balance sheet. These derivative instruments are recognized on the balance sheet at their fair value.

In addition, commitments to fund certain mortgage loans (interest rate lock commitments) and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. At June 30, 2013, the notional amount of the interest rate lock commitments and forward commitments were $26.9 million and $36.1 million, respectively. At December 31, 2012, the notional amount of the interest rate lock commitments and forward commitments were $23.4 million and $32.0 million, respectively. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans to third party investors when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitment to fund the loans. All derivative instruments are recognized on the balance sheet at their fair value.

Old National also enters into derivative instruments for the benefit of its customers. The notional amounts of these customer derivative instruments and the offsetting counterparty derivative instruments were $449.0 million and $449.0 million, respectively, at June 30, 2013. At December 31, 2012, the notional amounts of the customer derivative instruments and the offsetting counterparty derivative instruments were $456.1 million and $456.1 million, respectively. These derivative contracts do not qualify for hedge accounting. These instruments include interest rate swaps, caps, foreign exchange forward contracts and commodity swaps and options. Commonly, Old National will economically hedge significant exposures related to these derivative contracts entered into for the benefit of customers by entering into offsetting contracts with approved, reputable, independent counterparties with substantially matching terms.

Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. Old National’s exposure is limited to the replacement value of the contracts rather than the notional, principal or contract amounts. There are provisions in our agreements with the counterparties that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed thresholds are collateralized. In addition, the Company minimizes credit risk through credit approvals, limits, and monitoring procedures.

The following tables summarize the fair value of derivative financial instruments utilized by Old National:

Goodwill and Other Intangible Assets

NOTE 11 – GOODWILL AND OTHER INTANGIBLE ASSETS

The following table shows the changes in the carrying amount of goodwill by segment for the six months ended June 30, 2013 and 2012:

	Community
(dollars in thousands)	Banking		Other		Total
Balance, January 1, 2013	$	297,055	$	41,765	$	338,820

Goodwill acquired during the period		—		—		—
Balance, June 30, 2012	$	212,412	$	40,765	$	253,177

Goodwill is reviewed annually for impairment. Old National completed its most recent annual goodwill impairment test as of August 31, 2012 and concluded that, based on current events and circumstances, it is not more likely than not that the carry value of goodwill exceeds fair value. During the second quarter of 2013, Old National recorded $0.6 million of goodwill primarily related to the final pension settlement associated with the Indiana Community Bancorp acquisition. This was allocated to the “Community Banking” segment. During the second half of 2012, Old National recorded $85.6 million of goodwill associated with the acquisition of Indiana Community Bancorp, of which $84.6 million was allocated to the “Community Banking” segment and $1.0 million to the “Other” segment.

The gross carrying amount and accumulated amortization of other intangible assets at June 30, 2013 and December 31, 2012 was as follows:

			Accumulated
	Gross Carrying		Amortization			Net Carrying
(dollars in thousands)	Amount		and Impairment			Amount
June 30, 2013
Amortized intangible assets:
Core deposit	$	40,559	$	(28,772	)	$	11,787

Customer trust relationships		5,352		(1,453	)		3,899
Customer loan relationships		4,413		(2,574	)		1,839
Total intangible assets	$	76,873	$	(51,880	)	$	24,993

Customer trust relationships		5,352		(1,080	)		4,272
Customer loan relationships		4,413		(2,374	)		2,039
Total intangible assets	$	76,735	$	(47,515	)	$	29,220

Other intangible assets consist of core deposit intangibles and customer relationship intangibles and are being amortized primarily on an accelerated basis over their estimated useful lives, generally over a period of 5 to 15 years. During the second quarter of 2013, Old National increased customer business relationships by $0.1 million related to the purchase of an insurance book of business, which is included in the “Other” segment. During the third quarter of 2012, Old National increased core deposit intangibles by $1.3 million related to the acquisition of Indiana Community Bancorp, which is included in the “Community Banking” segment. Also during the third quarter of 2012, Old National increased customer relationship intangibles by $1.7 million associated with the trust business of Indiana Community Bancorp, which is included in the “Other” segment. During the second quarter of 2012, Old National increased customer business relationships by $0.5 million relating to the purchase of an insurance book of business, which is included in the “Other” segment.

Old National reviews other intangible assets for possible impairment whenever events or changes in circumstances indicate that carrying amounts may not be recoverable. No impairment charges were recorded in 2013 or 2012. Total amortization expense associated with other intangible assets for the six months ended June 30 was $4.4 million in 2013 and $3.9 million in 2012. Included in expense for the first quarter of 2013 is $0.6 million related to the branch sales that occurred in the first quarter.

Other is comprised of the parent company, the purchased credit impaired loan portfolio, and several smaller business units including insurance, wealth management and brokerage. It includes unallocated corporate overhead and intersegment revenue and expense eliminations.

In order to measure performance for each segment, Old National allocates capital and corporate overhead to each segment. Capital and corporate overhead are allocated to each segment using various methodologies, which are subject to periodic changes by management. Intersegment sales and transfers are not significant.

Old National uses a funds transfer pricing (“FTP”) system to eliminate the effect of interest rate risk from net interest income in the community banking segment and from companies included in the “other” column. The FTP system is used to credit or charge each segment for the funds the segments create or use. The net FTP credit or charge is reflected in segment net interest income.

The financial information for each operating segment is reported on the basis used internally by Old National’s management to evaluate performance and is not necessarily comparable with similar information for any other financial institution.

Summarized financial information concerning segments is shown in the following table for the three and six months ended June 30:

Included in net interest income for the three and six months ended June 30, 2013 in the Community Banking segment is approximately $9.8 million and $18.5 million, respectively, associated with Indiana Community Bancorp (“IBT”), acquired on September 15, 2012. Included in noninterest income for the three and six months ended June 30, 2013 in the Community Banking segment is approximately $2.1 million and $4.2 million, respectively, associated with the acquisition of IBT.

Noninterest expense for the six months ended June 30, 2013 includes $1.0 million of costs in the Community Banking segment associated with the acquisition of IBT.

Provision for loan losses resulted in recapture during the three and six months ended June 30, 2013. The recapture recorded in the Community Banking segment was primarily a result of the continuing trend in improved credit quality and the lower loss rates applied to the performing loan portfolio as charge-offs continue to decrease over time.

The recapture of provision expense recorded in the “Other” segment during the three and six months ended June 30, 2013 was reflective of recoveries associated with the purchased credit impaired loan portfolio accounted for in accordance with ASC-310-30. The provision for loan losses in this segment during 2012 related primarily to our FDIC-assisted transaction which closed in July 2011.

Guarantees [Abstract]

Financial Guarantees

NOTE 19 – FINANCIAL GUARANTEES

Old National holds instruments, in the normal course of business with clients, that are considered financial guarantees in accordance with FASB ASC 460-10 (FIN 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others), which requires the Company to record the instruments at fair value. Standby letters of credit guarantees are issued in connection with agreements made by clients to counterparties. Standby letters of credit are contingent upon failure of the client to perform the terms of the underlying contract. Credit risk associated with standby letters of credit is essentially the same as that associated with extending loans to clients and is subject to normal credit policies. The term of these standby letters of credit is typically one year or less. At June 30, 2013, the notional amount of standby letters of credit was $71.5 million, which represents the maximum amount of future funding requirements, and the carrying value was $0.3 million. At December 31, 2012, the notional amount of standby letters of credit was $63.4 million, which represents the maximum amount of future funding requirements, and the carrying value was $0.4 million.

During the second quarter of 2007, Old National entered into a risk participation in an interest rate swap. The interest rate swap had a notional amount of $8.3 million at June 30, 2013.

NOTE 18 – COMMITMENTS AND CONTINGENCIES

LITIGATION

In the normal course of business, Old National Bancorp and its subsidiaries have been named, from time to time, as defendants in various legal actions. Certain of the actual or threatened legal actions include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages.

Old National contests liability and/or the amount of damages as appropriate in each pending matter. In view of the inherent difficulty of predicting the outcome of such matters, particularly in cases where claimants seek substantial or indeterminate damages or where investigations and proceedings are in the early stages, Old National cannot predict with certainty the loss or range of loss, if any, related to such matters, how or if such matters will be resolved, when they will ultimately be resolved, or what the eventual settlement, or other relief, if any, might be. Subject to the foregoing, Old National believes, based on current knowledge and after consultation with counsel, that the outcome of such pending matters will not have a material adverse effect on the consolidated financial condition of Old National, although the outcome of such matters could be material to Old National’s operating results and cash flows for a particular future period, depending on, among other things, the level of Old National’s revenues or income for such period. Old National will accrue for a loss contingency if (1) it is probable that a future event will occur and confirm the loss and (2) the amount of the loss can be reasonably estimated.

In November 2010, Old National was named in a class action lawsuit in Vanderburgh County Circuit Court challenging Old National Bank’s checking account practices associated with the assessment of overdraft fees. The theory set forth by plaintiffs in this case is similar to other class action complaints filed against other financial institutions in recent years and settled for substantial amounts. On May 1, 2012, the plaintiff was granted permission to file a First Amended Complaint which named additional plaintiffs and amended certain claims. The plaintiffs seek damages and other relief, including restitution. On June 13, 2012, Old National filed a motion to dismiss the First Amended Complaint, which was subsequently denied by the Court. On September 7, 2012, the plaintiffs filed a motion for class certification, which was granted on March 20, 2013, and provides for a class of “All Old National Bank customers in the State of Indiana who had one or more consumer accounts and who, within the applicable statutes of limitation through August 15, 2010, incurred an overdraft fee as a result of Old National Bank’s practice of sequencing debit card and ATM transactions from highest to lowest.” Old National sought an interlocutory appeal on the issue of class certification on April 2, 2013, which was subsequently denied. Old National does not believe there is a cause of action under Indiana law to support the plaintiffs’ claims. Accordingly, on June 11, 2013, Old National moved for summary judgment and this motion is now pending with the Court. The case is currently scheduled for trial on October 7, 2013, although this trial date is subject to the completion of discovery and the ruling on the pending motion for summary judgment. Old National believes it has meritorious defenses to the claims brought by the plaintiffs. At this phase of the litigation, it is not possible for management of Old National to determine the probability of a material adverse outcome or reasonably estimate the amount of any loss.

LEASES

Old National rents certain premises and equipment under operating leases, which expire at various dates. Many of these leases require the payment of property taxes, insurance premiums, maintenance and other costs. In some cases, rentals are subject to increase in relation to a cost-of-living index. The leases have original terms ranging from less than one year to twenty-four years, and Old National has the right, at its option, to extend the terms of certain leases for four additional successive terms of five years. The Company does not have any material sub-lease agreements.

As of June 30, 2013 and 2012, Old National had $79.9 million and $87.4 million, respectively, of deferred gains remaining associated with prior sale leaseback transactions. The leases had original terms ranging from five to twenty-four years. These gains will be recognized over the remaining term of the leases.

CREDIT-RELATED FINANCIAL INSTRUMENTS

In the normal course of business, Old National’s banking affiliates have entered into various agreements to extend credit, including loan commitments of $1.237 billion and standby letters of credit of $71.5 million at June 30, 2013. At June 30, 2013, approximately $1.190 billion of the loan commitments had fixed rates and $47 million had floating rates, with the floating interest rates ranging from 0% to 26.25%. At December 31, 2012, loan commitments were $1.253 billion and standby letters of credit were $63.4 million. These commitments are not reflected in the consolidated financial statements. At June 30, 2013 and December 31, 2012, the balance of the allowance for unfunded loan commitments was $2.4 million and $4.0 million, respectively.

At June 30, 2013 and December 31, 2012, Old National had credit extensions of $13.7 million and $13.3 million, respectively, with various unaffiliated banks related to letter of credit commitments issued on behalf of Old National’s clients. At June 30, 2013 and December 31, 2012, Old National provided collateral to the unaffiliated banks to secure credit extensions totaling $10.4 million and $11.2 million, respectively. Old National did not provide collateral for the remaining credit extensions.

Basis of Presentation

NOTE 1 – BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned affiliates (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The allowance for loan losses, valuation of purchased loans, valuation and impairment of securities, goodwill and intangibles, derivative financial instruments, and income taxes are particularly subject to change. In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of Old National as of June 30, 2013 and 2012, and December 31, 2012, and the results of its operations for the three and six months ended June 30, 2013 and 2012. Interim results do not necessarily represent annual results. These financial statements should be read in conjunction with Old National’s Annual Report for the year ended December 31, 2012.

All significant intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform with the 2013 presentation. Such reclassifications had no effect on net income or shareholders’ equity.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Pronouncements

NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS

FASB ASC 805 – In October 2012, the FASB issued an update (ASU No. 2012-06, Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution) impacting FASB ASC 805, Business Combinations. This update specifies that when an entity recognizes an indemnification asset as a result of a government-assisted acquisition of a financial institution and subsequently a change in the cash flows expected to be collected on the indemnification asset occurs, the entity should subsequently account for the change in the measurement of the indemnification asset on the same basis as the change in the assets subject to indemnification. Any amortization of changes in value should be limited to the contractual term of the indemnification agreement (the lesser of the term of the indemnification agreement and the remaining life of the indemnified assets). This update became effective for interim and annual periods beginning on or after December 15, 2012, and is consistent with the Company’s accounting treatment of changes in expected cash flows and the indemnification asset and did not have a material impact on the consolidated financial statements.

FASB ASC 220 – In February 2013, the FASB issued an update (ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income) impacting FASB ASC 220, Comprehensive Income. This update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income. An entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about these amounts. This update became effective for the Company for interim and annual periods beginning after December 15, 2012 and did not have a material impact on the consolidated financial statements.

FASB ASC 405 – In February 2013, the FASB issued an update (ASU No. 2013-04, Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date) impacting FASB ASC 405, Liabilities. This update requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date as the sum of (1) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. This update also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. This update becomes effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements, but it is not expected to have a material impact.

FASB ASC 405 – In July 2013, the FASB issued an update (ASU No. 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes) impacting FASB ASC 815, Derivatives and Hedging. This update permits the Fed Funds Effective Swap Rate (Overnight Index Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes in addition to interest rates on direct Treasury obligations of the U.S. government and the London Interbank Offered Rate. This will provide a more comprehensive spectrum of interest rate resets to utilize as the designated benchmark interest rate risk component under the hedge accounting guidance. The amendments in this update are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company is currently evaluating the impact of adopting the new guidance on the consolidated financial statements, but it is not expected to have a material impact.

Fair Value Disclosures [Abstract]

Fair Value

NOTE 21 – FAIR VALUE

FASB ASC 820-10 defines fair value as 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. FASB ASC 820-10 also establishes a 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. The standard describes 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 that the entity has the ability to access as of the measurement date.

• 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; or 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.

Old National used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Investment securities: The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). 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 (Level 3). Discounted cash flows are calculated using swap and libor curves plus spreads that adjust for loss severities, volatility, credit risk 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.

Residential loans held for sale: The fair value of loans held for sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan (Level 2).

Derivative financial instruments: The fair values of derivative financial instruments are based on derivative valuation models using market data inputs as of the valuation date (Level 2).

Assets and liabilities measured at fair value on a recurring basis, including financial assets and liabilities for which the Company has elected the fair value option, are summarized below:

Included in the income statement is $11 thousand of income included in interest income from the accretion of discounts on securities. The increase in fair value is reflected in the balance sheet as an increase in the fair value of investment securities available-for sale, an increase in accumulated other comprehensive income, which is included in shareholders’ equity, and a decrease in other assets related to the tax impact.

$32.8 million of mutual fund securities were transferred from Level 2 to Level 1 as of December 31, 2012 because Old National could obtain quoted prices for the securities.

Included in the income statement is $11 thousand of income included in interest income from the accretion of discounts on securities and $161 thousand of credit losses included in noninterest income. The increase in fair value is reflected in the balance sheet as an increase in the fair value of investment securities available-for sale, an increase in accumulated other comprehensive income, which is included in shareholders’ equity, and a decrease in other assets related to the tax impact.

The table below provides quantitative information about significant unobservable inputs used in fair value measurements within Level 3 of the fair value hierarchy:

(a) Assuming no prepayments.

(b) Each currently performing pool asset is assigned a default probability based on the banking environment, which is adjusted for specific issuer evaluation, of 0%, 50% or 100%.

(c) Each currently defaulted pool asset is assigned a recovery probability based on specific issuer evaluation of 0%, 25% or 100%.

The significant unobservable inputs used in the fair value measurement for pooled trust preferred securities are prepayment rates, assumed additional pool asset defaults and expected return to performing status of defaulted pool assets. Significant changes in any of the inputs in isolation would result in a significant change to the fair value measurement. Three of the five pooled trust preferred securities Old National owns are subordinate note classes that rely on an ongoing cash flow stream to support their values. The senior note classes receive the benefit of prepayments to the detriment of subordinate note classes since the ongoing interest cash flow stream is reduced by the early redemption. Generally, a change in prepayment rates or additional pool asset defaults has an impact that is directionally opposite from a change in the expected recovery of a defaulted pool asset.

Assets measured at fair value on a non-recurring basis are summarized below:

Impaired commercial and commercial real estate loans that are deemed collateral dependent are valued based on the fair value of the underlying collateral. These estimates are based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These impaired commercial and commercial real estate loans had a principal amount of $32.5 million, with a valuation allowance of $7.2 million at June 30, 2013. Old National recorded $3.9 million of provision expense associated with these loans for the six months ended June 30, 2013.

Other real estate owned and other repossessed property is measured at fair value less costs to sell and had a net carrying amount of $21.6 million. The estimates of fair value are based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These appraisals are discounted 0% to 45% depending on the type of property and the type of appraisal (market value vs. liquidation value). There were net write-downs of other real estate owned of $2.1 million in the first six months of 2013.

During the second quarter of 2013, finance leases of $11.6 million were transferred from the commercial loan category at fair value, which is the offer price, and a loss of $0.2 million was recognized.

As of December 31, 2012, impaired commercial and commercial real estate loans had a principal amount of $34.1 million, with a valuation allowance of $6.8 million. Old National recorded $4.0 million of provision expense associated with these loans in 2012.

Other real estate owned and other repossessed property is measured at fair value less costs to sell and had a net carrying amount of $24.5 million at December 31, 2012. There were write-downs of other real estate owned of $15.3 million in 2012.

The table below provides quantitative information about significant unobservable inputs used in fair value measurements within Level 3 of the fair value hierarchy:

Residential		593	Fair value of collateral	Discount for type of property, age of appraisal and current status	10% - 45% (25%)

Collateral dependent loans, other real estate owned and other repossessed property are valued based on the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property and other related factors to estimate the current value of the collateral. These appraisals are discounted depending on the type of property and the type of appraisal (market value vs. liquidation value).

Financial instruments recorded using fair value option

Under FASB ASC 825-10, the Company may elect to report most financial instruments and certain other items at fair value on an instrument-by instrument basis with changes in fair value reported in net income. After the initial adoption, the election is made at the acquisition of an eligible financial asset, financial liability or firm commitment or when certain specified reconsideration events occur. The fair value election may not be revoked once an election is made.

The Company has elected the fair value option for residential mortgage loans held for sale. For these loans, interest income is recorded in the consolidated statements of income based on the contractual amount of interest income earned on the financial assets (except any that are on nonaccrual status). None of these loans are 90 days or more past due, nor are any on nonaccrual status. Included in the income statement are $105 thousand and $206 thousand of interest income for residential loans held for sale for the three and six months ended June 30, 2013, respectively. Included in the income statement are $34 thousand and $65 thousand of interest income for residential loans held for sale for the three and six months ended June 30, 2012, respectively.

Residential mortgage loans held for sale

Old National has elected the fair value option for newly originated conforming fixed-rate and adjustable-rate first mortgage loans held for sale. These loans are intended for sale and are hedged with derivative instruments. Old National has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplification. The fair value option was not elected for loans held for investment.

As of June 30, 2013, the difference between the aggregate fair value and the aggregate remaining principal balance for loans for which the fair value option has been elected is as follows. Accrued interest at period end is included in the fair value of the instruments.

	Aggregate					Contractual

The following methods and assumptions were used to estimate the fair value of each type of financial instrument.

Cash, due from banks, federal funds sold and resell agreements and money market investments: For these instruments, the carrying amounts approximate fair value (Level 1).

Investment securities: Fair values for investment securities held-to-maturity are based on quoted market prices, if available. For securities where quoted prices are not available, fair values are estimated based on market prices of similar securities (Level 2).

Federal Home Loan Bank Stock: Old National Bank is a member of the Federal Home Loan Bank system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. The carrying value of Federal Home Loan Bank stock approximates fair value based on the redemption provisions of the Federal Home Loan Bank (Level 2).

Loans: The fair value of loans is estimated by discounting future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities (Level 3).

Covered loans: Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting current market rates for new originations of comparable loans adjusted for the risk inherent in the cash flow estimates. Loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques (Level 3).

FDIC indemnification asset: The loss sharing asset was measured separately from the related covered assets as it is not contractually embedded in the assets and is not transferable with the assets should the Bank choose to dispose of the assets. Fair value was originally estimated using projected cash flows related to the loss sharing agreement based on the expected reimbursements for losses and the applicable loss sharing percentage and these projected cash flows are updated with the cash flow estimates on covered assets. These cash flows were discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC (Level 3).

Accrued interest receivable and payable: The carrying amount approximates fair value and is aligned with the underlying assets or liabilities (Level 1, Level 2 or Level 3).

Deposits: The fair value of noninterest-bearing demand deposits and savings, NOW and money market deposits is the amount payable as of the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit is estimated using rates currently offered for deposits with similar remaining maturities (Level 2).

Short-term borrowings: Federal funds purchased and other short-term borrowings generally have an original term to maturity of 30 days or less and, therefore, their carrying amount is a reasonable estimate of fair value (Level 1). The fair value of securities sold under agreements to repurchase is determined using end of day market prices (Level 1).

Other borrowings: The fair value of medium-term notes, subordinated debt and senior bank notes is determined using market quotes (Level 2). The fair value of FHLB advances is determined using calculated prices for new FHLB advances with similar risk characteristics (Level 3). The fair value of other debt is determined using comparable security market prices or dealer quotes (Level 2).

Standby letters of credit: Fair values for standby letters of credit are based on fees currently charged to enter into similar agreements. The fair value for standby letters of credit was recorded in “Accrued expenses and other liabilities” on the consolidated balance sheet in accordance with FASB ASC 460-10 (FIN 45) (Level 3).

Off-balance sheet financial instruments: Fair values for off-balance sheet credit-related financial instruments are based on fees currently charged to enter into similar agreements. For further information regarding the amounts of these financial instruments, see Notes 18 and 19.

Loans Held for Sale

NOTE 7 – LOANS HELD FOR SALE

Residential loans that Old National has committed to sell are recorded at fair value in accordance with FASB ASC 825-10 (SFAS No. 159 – The Fair Value Option for Financial Assets and Financial Liabilities). At June 30, 2013 and December 31, 2012, Old National had residential loans held for sale of $13.6 million and $12.6 million, respectively.

At June 30, 2013, Old National had taxable finance leases held for sale of $11.6 million. These leases were transferred from the commercial loan category at fair value and a loss of $0.2 million was recognized. The portfolio of leases held for sale has an average maturity of 2.7 years and interest rates ranging from 3.57% to 10.22%. The leases held for sale are to a variety of borrowers, with various types of equipment securing the leases, and all of the leases are current. Old National does not intend to sell its nontaxable finance leases.

During the first six months of 2013, commercial and commercial real estate loans held for investment of $3.6 million, including $0.4 million of purchased impaired loans, were reclassified to loans held for sale at the lower of cost or fair value and sold for $4.8 million, resulting in a charge-off of $0.2 million, recoveries of $0.4 million and other income of $1.0 million. At June 30, 2013, there were no loans held for sale under this arrangement.

During the first six months of 2012, commercial and commercial real estate loans held for investment of $1.6 million, including $1.5 million of purchased impaired loans, were reclassified to loans held for sale at the lower of cost or fair value and sold for $2.2 million, resulting in a charge-off of $0.1 million and a recovery of $0.7 million. At June 30, 2012, there were no loans held for sale under this arrangement.

Income Taxes

NOTE 16 – INCOME TAXES

Following is a summary of the major items comprising the differences in taxes from continuing operations computed at the federal statutory rate and as recorded in the consolidated statement of income for the three and six months ended June 30:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
(dollars in thousands)	2013			2012			2013			2012
Provision at statutory rate of 35%	$	14,774		$	13,333		$	26,792		$	23,855
Tax-exempt income		(3,092	)		(2,636	)		(5,989	)		(5,146	)
State income taxes		1,156			1,133			2,372			2,027
State statutory rate change		1,257			—			1,257			—
Interim period effective rate adjustment		(358	)		(723	)		(223	)		(706	)
Other, net		(3	)		(218	)		(83	)		(801	)
Income tax expense	$	13,734		$	10,889		$	24,126		$	19,229
Effective tax rate		32.5	%		28.6	%		31.5	%		28.2	%

In accordance with ASC 740-270, Accounting for Interim Reporting, the provision for income taxes was recorded at June 30, 2013 and 2012 based on the current estimate of the effective annual rate.

For the six months ended June 30, 2013, the effective tax rate was higher than the six months ended June 30, 2012. The higher tax rate in the first six months of 2013 is the result of an increase in projected pre-tax book income while tax-exempt income remained relatively stable combined with an increase in income tax expense of approximately $1.3 million related to a statutory rate change during the second quarter of 2013.

No valuation allowance was recorded at June 30, 2013 and 2012 because, based on our current expectations, Old National believes that it will generate sufficient income in the future years to realize deferred tax assets.

Unrecognized Tax Benefits

The Company and its subsidiaries file a consolidated U.S. federal income tax return, as well as filing various state returns. Unrecognized state income tax benefits are reported net of their related deferred federal income tax benefit.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

(dollars in thousands)	2013		2012
Balance at January 1	$	3,953	$	4,145
Additions (reductions) based on tax positions related to the current year		8		1
Balance at June 30	$	3,961	$	4,146

Approximately $0.17 million of unrecognized tax benefits, if recognized, would favorably affect the effective income tax rate in future periods.

Proceeds from sales and calls of securities available for sale were $307.4 million and $197.3 million for the six months ended June 30, 2013 and 2012, respectively. Gains of $2.5 million and $7.6 million were realized on these sales during 2013 and 2012, respectively. Also included in net securities gains for the first six months of 2013 is $204 thousand of gains associated with the trading securities and $195 thousand of gains from mutual funds. There were no other-than-temporary impairment charges related to credit loss in the first six months of 2013. Impacting earnings in the first six months of 2012 was $45 thousand of gains associated with the trading securities and other-than-temporary impairment charges related to credit loss on five non-agency mortgage-backed securities and one trust preferred security in the amount of $876 thousand.

Trading securities, which consist of mutual funds held in a trust associated with deferred compensation plans for former Monroe Bancorp directors and executives, are recorded at fair value and totaled $3.3 million at June 30, 2013 and $3.1 million at December 31, 2012.

During the third quarter of 2012, approximately $46.1 million of state and political subdivision securities were transferred from the held-to-maturity portfolio to the available-for-sale portfolio due to changes in circumstances associated with the Office of Management and Budget’s report outlining sequestration and the implications for taxable Build America Bonds. Specifically, the release indicated that if U.S. policymakers failed to address the fiscal cliff and take legislative action, a series of key fiscal measures would occur in January. One of these measures that involves automatic spending cuts (or “sequestration”) mandated by the Budget Control Act had, among other things, implications for taxable “Build America Bonds” (“BABs”). The OMB included in its report that 7.6%, or $322 million, of subsidy payments authorized for issuers of BABs would be reduced in 2013. This cut could in turn trigger an “Extraordinary Redemption Provision” within the BAB structure allowing the issuer to potentially call some bonds at par. This par call could generate a large loss for buyers of BABs if they paid a premium for these securities at purchase.

Old National owns a significant number of premium BABs, largely classified as held-to-maturity securities, that would generate a loss if called at par. In response to this event and consistent with FASB ASC 320-10-25-6, Old National moved certain BABs from held-to-maturity to available-for-sale based on the following criteria:

1) BABS that were purchased at a premium;

2) BABS with a par value of $1.0 million or more (BABS with a par value below $1.0 million remained in held-to-maturity as, in management’s opinion, they would not have a material negative impact on earnings if called at par).

Once these BABS were reclassified, Old National reviewed each holding for potential sale in order to limit any negative earnings impact.

Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. Investment securities classified as available-for-sale or held-to-maturity are generally evaluated for OTTI under FASB ASC 320 (SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities). However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in FASB ASC 325-10 (EITF Issue No. 99-20, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets).

In determining OTTI under the FASB ASC 320 (SFAS No. 115) model, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. The second segment of the portfolio uses the OTTI guidance provided by FASB ASC 325-10 (EITF 99-20) that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the FASB ASC 325-10 model, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.

When other-than-temporary-impairment occurs under either model, the amount of the other-than-temporary-impairment recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary-impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. Otherwise, the other-than-temporary-impairment shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total other-than-temporary-impairment related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total other-than-temporary-impairment related to other factors shall be recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the other-than-temporary-impairment recognized in earnings shall become the new amortized cost basis of the investment.

There was no other-than-temporary-impairment recorded in the first six months of 2013. In the first half of 2012, $0.9 million of other-than-temporary-impairment was recorded.

As of June 30, 2013, Old National’s securities portfolio consisted of 1,328 securities, 374 of which were in an unrealized loss position. Unrealized losses related to Old National’s holdings of pooled trust preferred securities have remained for the longest continuous period of time and are discussed below.

Pooled Trust Preferred Securities

At June 30, 2013, the Company’s securities portfolio contained five pooled trust preferred securities with a fair value of $9.2 million and unrealized losses of $13.9 million. Three of the pooled trust preferred securities in our portfolio fall within the scope of FASB ASC 325-10 (EITF 99-20) and have a fair value of $3.2 million with unrealized losses of $5.6 million at June 30, 2013. These securities were rated A2 and A3 at inception, but at June 30, 2013, one security was rated CC, one security was rated C and one security D. The issuers in these securities are primarily banks, but some of the pools do include a limited number of insurance companies. The Company uses the OTTI evaluation model to compare the present value of expected cash flows to the previous estimate to determine whether an adverse change in cash flows has occurred during the quarter. The OTTI model considers the structure and term of the collateralized debt obligation (“CDO”) and the financial condition of the underlying issuers. Specifically, the model details interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes. The current estimate of expected cash flows is based on the most recent trustee reports and any other relevant market information including announcements of interest payment deferrals or defaults of underlying trust preferred securities. Assumptions used in the model include expected future default rates and prepayments. We assume no recoveries on defaults and a limited number of recoveries on current or projected interest payment deferrals. In addition, we use the model to “stress” each CDO, or make assumptions more severe than expected activity, to determine the degree to which assumptions could deteriorate before the CDO could no longer fully support repayment of Old National’s note class. For the six months ended June 30, 2013, our model indicated no other-than-temporary-impairment losses on these securities. During the first quarter of 2013 one of these securities was sold. The Company recorded a gain of $224 thousand associated with this sale. At June 30, 2013, the Company has no intent to sell any of these securities that are in an unrealized loss position.

Two of our pooled trust preferred securities with a fair value of $6.0 million and unrealized losses of $8.3 million at June 30, 2013 are not subject to FASB ASC 325-10. These securities are evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. Our analysis indicated no other-than-temporary-impairment on these securities.

For the six months ended June 30, 2012, the six securities subject to FASB ASC 325-10 accounted for $7.1 million of the unrealized losses in the pooled trust preferred securities category. For the six months ended June 30, 2012, our model indicated other-than-temporary-impairment losses on one security of $161 thousand, all of which was recorded as a credit loss in earnings. At June 30, 2012, the fair value of this security was $475 thousand and it was classified as available for sale.

Two of our pooled trust preferred securities with a fair value of $4.6 million and unrealized losses of $9.7 million at June 30, 2012 were not subject to FASB ASC 325-10. These securities were evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. Our analysis indicated no other-than-temporary-impairment on these securities.

The table below summarizes the relevant characteristics of our five pooled trust preferred securities as well as five single issuer trust preferred securities which are included with other securities in Note 6 to the consolidated financial statements. Each of the pooled trust preferred securities support a more senior tranche of security holders except for the MM Community Funding II security which, due to payoffs, Old National is now in the most senior class.

As depicted in the table below, all five securities have experienced credit defaults. However, two of these securities have excess subordination and are not other-than-temporarily-impaired as a result of their class hierarchy which provides more loss protection.

Covered Loans

NOTE 9 – COVERED LOANS

Covered loans represent loans acquired from the FDIC that are subject to loss share agreements. The carrying amount of covered loans was $288.6 million at June 30, 2013. The composition of covered loans by lending classification was as follows:

	At June 30, 2013
	Loans Accounted for			Loans excluded from
	Under ASC 310-30			ASC 310-30 (1)
	(Purchased Credit			(Not Purchased		Total Covered

Covered loans		180,407			108,170		288,577
Allowance for loan losses		(5,428	)		—		(5,428	)
Covered loans, net	$	174,979		$	108,170	$	283,149

(1) Includes loans with revolving privileges which are scoped out of FASB ASC 310-30 and certain loans which Old National elected to treat under the cost recovery method of accounting.

Loans were recorded at fair value in accordance with FASB ASC 805, Business Combinations. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. Loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in FASB ASC 820, exclusive of the loss share agreements with the Federal Deposit Insurance Corporation (“FDIC”). The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of undiscounted expected principal, interest and other cash flows.

The outstanding balance of covered loans accounted for under ASC 310-30, including contractual principal, interest, fees and penalties, was $446.3 million and $529.2 million as of June 30, 2013 and December 31, 2012, respectively.

The following table is a roll-forward of acquired impaired loans accounted for under ASC 310-30 for the six months ended June 30, 2013:

	Contractual			Nonaccretable			Accretable			Carrying
(dollars in thousands)	Cash Flows (1)			Difference			Yield			Amount
Balance at January 1, 2013	$	424,527		$	(90,996	)	$	(85,779	)	$	247,752
Principal reductions and interest payments		(78,174	)		—			—			(78,174	)
Accretion of loan discount		—			—			19,174			19,174
Changes in contractual and expected cash flows due to remeasurement		(14,514	)		23,521			(8,873	)		134
Removals due to foreclosure or sale		(7,764	)		948			(1,663	)		(8,479	)
Balance at June 30, 2013	$	324,075		$	(66,527	)	$	(77,141	)	$	180,407

(1) The balance of contractual cash flows includes future contractual interest and is net of amounts charged off and interest collected on nonaccrual loans.

The following table is a roll-forward of acquired impaired loans accounted for under ASC 310-30 for the six months ended June 30, 2012:

	Contractual			Nonaccretable			Accretable			Carrying
(dollars in thousands)	Cash Flows (1)			Difference			Yield			Amount
Balance at January 1, 2012	$	729,496		$	(180,655	)	$	(92,053	)	$	456,788
Principal reductions and interest payments		(116,204	)		—			—			(116,204	)

Changes in contractual and expected cash flows due to remeasurement		13,829			16,532			(35,678	)		(5,317	)
Removals due to foreclosure or sale		(17,030	)		8,952			1,326			(6,752	)
Balance at June 30, 2012	$	610,091		$	(155,171	)	$	(100,303	)	$	354,617

(1) The balance of contractual cash flows includes future contractual interest and is net of amounts charged off and interest collected on nonaccrual loans.

Over the life of the acquired loans, the Company continues to estimate cash flows expected to be collected on individual loans or on pools of loans sharing common risk characteristics which were treated in the aggregate when applying various valuation techniques. The Company evaluates at each balance sheet date whether the present value of its loans determined using the effective interest rates has decreased and if so, recognizes a provision for loan losses. For any increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan’s or pool’s remaining life. Eighty percent of the prospective yield adjustments are offset as Old National will recognize a corresponding decrease in cash flows expected from the indemnification asset prospectively in a similar manner. The indemnification asset is adjusted over the shorter of the life of the underlying investment or the indemnification agreement.

Accretable yield, or income expected to be collected on the covered loans accounted for under ASC 310-30, is as follows:

(dollars in thousands)	2013			2012
Balance at January 1,	$	85,779		$	92,053
New loans purchased		—			—
Accretion of income		(19,174	)		(26,102	)
Reclassifications from (to) nonaccretable difference		8,873			35,678
Disposals/other adjustments		1,663			(1,326	)
Balance at June 30,	$	77,141		$	100,303

At June 30, 2013, the $100.4 million loss sharing asset is comprised of an $89.6 million FDIC indemnification asset and a $10.8 million FDIC loss share receivable. The loss share receivable represents actual incurred losses where reimbursement has not yet been received from the FDIC. The indemnification asset represents future cash flows the Company expects to collect from the FDIC under the loss sharing agreements and the amount related to the estimated improvements in cash flow expectations that are being amortized over the same period for which those improved cash flows are being accreted into income. At June 30, 2013, $63.8 million of the FDIC indemnification asset is related to expected indemnification payments and $25.8 million is expected to be amortized and reported in noninterest income as an offset to future accreted interest income.

For covered loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the quarterly re-measurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. As a result of this impairment, the indemnification asset is increased to reflect anticipated future cash flows to be received from the FDIC. Consistent with the loss sharing agreements between the Company and the FDIC, the amount of the increase to the indemnification asset is measured at 80% of the resulting impairment.

Alternatively, when the quarterly re-measurement results in an increase in expected future cash flows due to a decrease in expected credit losses, the nonaccretable difference decreases and the effective yield of the related loan portfolio is increased. As a result of the improved expected cash flows, the indemnification asset would be reduced first by the amount of any impairment previously recorded and, second, by increased amortization over the remaining life of the related loss sharing agreements.

The following table shows a detailed analysis of the FDIC loss sharing asset for the six months ended June 30, 2013 and 2012:

Loans and Allowance for Credit Losses

NOTE 8 – LOANS AND ALLOWANCE FOR CREDIT LOSSES

Old National’s finance receivables consist primarily of loans made to consumers and commercial clients in various industries including manufacturing, agribusiness, transportation, mining, wholesaling and retailing. Most of Old National’s lending activity occurs within the Company’s principal geographic markets of Indiana, Illinois and Kentucky. Old National has no concentration of commercial loans in any single industry exceeding 10% of its portfolio.

The composition of loans by lending classification was as follows:

	June 30,			December 31,
(dollars in thousands)	2013			2012
Commercial (1)	$	1,397,882		$	1,336,820

Allowance for loan losses—covered loans		(5,428	)		(5,716	)
Net loans	$	5,126,904		$	5,141,831

(1) Includes direct finance leases of $34.8 million at June 30, 2013 and $57.7 million at December 31, 2012.

Portfolio loans, or loans Old National intends to hold for investment purposes, are carried at the principal balance outstanding, net of earned interest, purchase premiums or discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the principal balances of loans outstanding.

The risk characteristics of each loan portfolio segment are as follows:

Commercial

Commercial loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.

Commercial real estate

These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing Old National’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, Old National avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans.

Included with commercial real estate are construction loans, which are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based on estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from Old National until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.

Residential

With respect to residential loans that are secured by 1-4 family residences and are generally owner occupied, Old National typically establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in residential property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Consumer

Home equity loans are typically secured by a subordinate interest in 1-4 family residences, and consumer loans are secured by consumer assets such as automobiles or recreational vehicles. Some consumer loans are unsecured such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in residential property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Covered Loans

On July 29, 2011, Old National acquired the banking operations of Integra Bank N.A. (“Integra”) in an FDIC assisted transaction. As part of the purchase and assumption agreement, the Company and the FDIC entered into loss sharing agreements (each, a “loss sharing agreement” and collectively, the “loss sharing agreements”), whereby the FDIC will cover a substantial portion of any future losses on loans (and related unfunded commitments), other real estate owned (“OREO”) and up to 90 days of certain accrued interest on loans. The acquired loans and OREO subject to the loss sharing agreements are referred to collectively as “covered assets.” Under the terms of the loss sharing agreements, the FDIC will reimburse Old National for 80% of losses up to $275.0 million, losses in excess of $275.0 million up to $467.2 million at 0% reimbursement, and 80% of losses in excess of $467.2 million. As of June 30, 2013, we do not expect losses to exceed $275.0 million. Old National will reimburse the FDIC for its share of recoveries with respect to losses for which the FDIC has reimbursed the Bank under the loss sharing agreements. The loss sharing provisions of the agreements for commercial and single family residential mortgage loans are in effect for five and ten years, respectively, from the July 29, 2011 acquisition date and the loss recovery provisions for such loans are in effect for eight years and ten years, respectively, from the acquisition date.

Allowance for loan losses

The allowance for loan losses is maintained at a level believed adequate by management to absorb probable losses incurred in the loan portfolio. Management’s evaluation of the adequacy of the allowance is an estimate based on reviews of individual loans, pools of homogeneous loans, historical loss experience, and assessments of the impact of current economic conditions on the portfolio.

The allowance is increased through a provision charged to operating expense. Loans deemed to be uncollectible are charged to the allowance. Recoveries of loans previously charged-off are added to the allowance.

No allowance was brought forward on any of the acquired loans as any credit deterioration evident in the loans was included in the determination of the fair value of the loans at the acquisition date. Purchased credit impaired (“PCI”) loans are not considered impaired until after the point at which there has been a degradation of cash flows below our expected cash flows at acquisition. Impairment on PCI loans would be recognized in the current period as provision expense.

Credit Quality

Old National’s management monitors the credit quality of its financing receivables in an on-going manner. Internally, management assigns a credit quality grade to each non-homogeneous commercial and commercial real estate loan in the portfolio. The primary determinants of the credit quality grade are based upon the reliability of the primary source of repayment and the past, present, and projected financial condition of the borrower. The credit quality rating also reflects current economic and industry conditions. Major factors used in determining the grade can vary based on the nature of the loan, but commonly include factors such as debt service coverage, internal cash flow, liquidity, leverage, operating performance, debt burden, FICO scores, occupancy, interest rate sensitivity, and expense burden. Old National uses the following definitions for risk ratings:

Criticized. Special mention loans that have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Classified – Substandard. Loans classified as substandard are inadequately protected by the current net 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 the institution will sustain some loss if the deficiencies are not corrected.

Classified – Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Pass rated loans are those loans that are other than criticized, classified – substandard or classified – doubtful.

As of June 30, 2013 and December 31, 2012, the risk category of loans, excluding covered loans, by class of loans is as follows:

Old National considers the performance of the loan portfolio and its impact on the allowance for loan losses. For residential and consumer loan classes, Old National also evaluates credit quality based on the aging status of the loan and by payment activity. The following table presents the recorded investment in residential and consumer loans based on payment activity as of June 30, 2013 and December 31, 2012, excluding covered loans:

Impaired Loans

Large commercial credits are subject to individual evaluation for impairment. Retail credits and other small balance credits that are part of a homogeneous group are not tested for individual impairment unless they are modified as a troubled debt restructuring. A loan is considered impaired when it is probable that contractual interest and principal payments will not be collected either for the amounts or by the dates as scheduled in the loan agreement. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported net, at the present value of estimated cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Old National’s policy, for all but purchased credit impaired loans, is to recognize interest income on impaired loans unless the loan is placed on nonaccrual status. For the six months ended June 30, 2013 and 2012, the average balance of impaired loans was $76.4 million and $72.0 million, respectively, for which no interest income was recorded. No additional funds are committed to be advanced in connection with these impaired loans.

The following table shows Old National’s impaired loans, excluding covered loans, that are individually evaluated as of June 30, 2013 and December 31, 2012. Of the loans purchased during 2012 and 2011 without FDIC loss share coverage, only those that have experienced subsequent impairment since the date acquired are included in the table below.

(1) The Company does not record interest on nonaccrual loans until principal is recovered.

For all loan classes, a loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectibility of principal or interest. Interest accrued during the current year on such loans is reversed against earnings. Interest accrued in the prior year, if any, is charged to the allowance for loan losses. Cash interest received on these loans is applied to the principal balance until the principal is recovered or until the loan returns to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, remain current for six months and future payments are reasonably assured.

Covered loans accounted for under FASB ASC Topic 310-30 accrue interest, even though they may be contractually past due, as any nonpayment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or prospective yield adjustments. Similar to uncovered loans, covered loans accounted for outside FASB ASC Topic 310-30 are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful. Information for covered loans accounted for both under and outside FASB ASC Topic 310-30 is included in the table below in the row labeled covered loans.

Loan Participations

Old National has loan participations, which qualify as participating interests, with other financial institutions. At June 30, 2013, these loans totaled $225.7 million, of which $140.6 million had been sold to other financial institutions and $85.1 million was retained by Old National. The loan participations convey proportionate ownership rights with equal priority to each participating interest holder, involve no recourse (other than ordinary representations and warranties) to, or subordination by, any participating interest holder, all cash flows are divided among the participating interest holders in proportion to each holder’s share of ownership and no holder has the right to pledge the entire financial asset unless all participating interest holders agree.

Troubled Debt Restructurings

Old National may choose to restructure the contractual terms of certain loans. The decision to restructure a loan, versus aggressively enforcing the collection of the loan, may benefit Old National by increasing the ultimate probability of collection.

Any loans that are modified are reviewed by Old National to identify if a troubled debt restructuring (“TDR”) has occurred, which is when for economic or legal reasons related to a borrower’s financial difficulties, the Bank grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. During the six months ended June 30, 2013, the terms of certain loans were modified as troubled debt restructurings. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date at a stated rate of interest lower than the current market rate of new debt with similar risk, or a permanent reduction of the recorded investment of the loan.

Loans modified in a troubled debt restructuring are typically placed on nonaccrual status until the Company determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrate a period of performance according to the restructured terms for six months.

If the Company is unable to resolve a nonperforming loan issue, the credit will be charged off when it is apparent there will be a loss. For large commercial type loans, each relationship is individually analyzed for evidence of apparent loss based on quantitative benchmarks or subjectively based upon certain events or particular circumstances. It is Old National’s policy to charge off small commercial loans scored through our small business credit center with contractual balances under $250,000 that have been placed on nonaccrual status or became ninety days or more delinquent, without regard to the collateral position. For residential and consumer loans, a charge off is recorded at the time foreclosure is initiated or when the loan becomes 120 to 180 days past due, whichever is earlier.

For commercial troubled debt restructurings, an allocated reserve is established within the allowance for loan losses for the difference between the carrying value of the loan and its computed fair value. To determine the fair value of the loan, one of the following methods is selected: (1) the present value of expected cash flows discounted at the loans original effective interest rate, (2) the loan’s observable market price, or (3) the fair value of the collateral value, if the loan is collateral dependent. The allocated reserve is established as the difference between the carrying value of the loan and the collectable value. If there are significant changes in the amount or timing of the loan’s expected future cash flows, impairment is recalculated and the valuation allowance is adjusted accordingly.

For consumer and residential troubled debt restructurings, an additional amount is added to the loan loss reserve that represents the difference in the present value of the cash flows between the original terms and the new terms of the modified loan, using the original effective interest rate of the loan as a discount rate.

At June 30, 2013, our troubled debt restructurings consisted of $11.4 million of commercial loans, $19.2 million of commercial real estate loans, $0.8 million of consumer loans and $0.7 million of residential loans, totaling $32.1 million. Approximately $21.5 million of the troubled debt restructuring at June 30, 2013 were included with nonaccrual loans. At December 31, 2012, our troubled debt restructurings consisted of $12.7 million of commercial loans, $18.4 million of commercial real estate loans, $0.5 million of consumer loans and $0.5 million of residential loans, totaling $32.1 million. Approximately $22.1 million of the troubled debt restructuring at December 31, 2012 were included with nonaccrual loans.

As of June 30, 2013 and December 31, 2012, Old National has allocated $3.9 million and $4.5 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings, respectively. Old National has not committed to lend any additional amounts as of June 30, 2013 and December 31, 2012, respectively, to customers with outstanding loans that are classified as troubled debt restructurings.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

The terms of certain other loans were modified during the six months ended June 30, 2013 that did not meet the definition of a troubled debt restructuring. It is our process to review all classified and criticized loans that, during the period, have been renewed, have entered into a forbearance agreement, have gone from principal and interest to interest only, or have had the maturity date extended. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on its debt in the foreseeable future without the modification. The evaluation is performed under the Company’s internal underwriting policy. We also evaluate whether a concession has been granted or if we were adequately compensated through a market interest rate, additional collateral or a bona fide guarantee. We also consider whether the modification was insignificant relative to the other terms of the agreement or if the delay in a payment was 90 days or less.

Purchased credit impaired (“PCI”) loans are not considered impaired until after the point at which there has been a degradation of cash flows below our expected cash flows at acquisition. If a PCI loan is subsequently modified, and meets the definition of a TDR, it will be removed from PCI accounting and accounted for as a TDR only if the PCI loan was being accounted for individually. If the purchased credit impaired loan is being accounted for as part of a pool, it will not be removed from the pool. As of June 30, 2013, it has not been necessary to remove any loans from PCI accounting.

In general, once a modified loan is considered a TDR, the loan will always be considered a TDR, and therefore impaired, until it is paid in full, otherwise settled, sold or charged off. However, our policy also permits for loans to be removed from troubled debt restructuring status in the years following the restructuring if the following two conditions are met: (1) The restructuring agreement specifies an interest rate equal to or greater than the rate that the Company was willing to accept at the time of the restructuring for a new loan with comparable risk, and (2) the loan is not impaired based on the terms specified by the restructuring agreement.

Purchased Impaired Loans (non-covered loans)

Purchased loans acquired in a business combination are recorded at estimated fair value on their purchase date with no carryover of the related allowance for loan and lease losses. In determining the estimated fair value of purchased loans, management considers a number of factors including the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, net present value of cash flows expected to be received, among others. Purchased loans are accounted for in accordance with guidance for certain loans acquired in a transfer (ASC 310-30), when the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the acquirer will not collect all contractually required principal and interest payments. The difference between contractually required payments and the cash flows expected to be collected at acquisition is referred to as the non-accretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan and lease losses. Subsequent increases in expected cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield, which would have a positive impact on interest income.

Old National has purchased loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected. Of these acquired credit impaired loans, $4.0 million in carrying balances did not meet the criteria to be accounted for under the guidance of ASC 310-30 as they were revolving lines of credit, thus these lines have not been included in the following table. For these noncovered loans that meet the criteria of ASC 310-30 treatment, the carrying amount is as follows:

	June 30,		December 31,

Commercial	$	440	$	7,859

Carrying amount, net of allowance	$	54,132	$	79,120
Allowance for loan losses	$	3,488	$	4,275

The outstanding balance of noncovered loans accounted for under ASC 310-30, including contractual principal, interest, fees and penalties, was $146.3 million and $179.5 million as of June 30, 2013 and December 31, 2012, respectively.

The accretable difference on purchased loans acquired in a business combination is the difference between the expected cash flows and the net present value of expected cash flows with such difference accreted into earnings using the effective yield method over the term of the loans. Accretion of $8.9 million has been recorded as loan interest income through the six months ended June 30, 2013. Accretion of $6.0 million was recorded as loan interest income through the six months ended June 30, 2012. Improvement in cash flow expectations has resulted in a reclassification from nonaccretable difference to accretable yield.

Accretable yield of noncovered loans, or income expected to be collected, is as follows:

Included in Old National’s allowance for loan losses was $4.3 million related to the purchased loans in 2012. An immaterial amount of allowances for loan losses were reversed during 2013 and 2012 related to these loans.

Purchased loans, as of the date of acquisition, for which it was probable that all contractually required payments would not be collected are as follows:

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]

Stock-Based Compensation

NOTE 15 – STOCK-BASED COMPENSATION

At June 30, 2013, Old National had 5.1 million shares remaining available for issuance under the Company’s Amended and Restated 2008 Incentive Compensation Plan. The granting of awards to key employees is typically in the form of restricted stock awards or units.

Restricted Stock Awards

The Company granted 75 thousand time-based restricted stock awards to certain key officers during the first six months of 2013, with shares vesting at the end of a thirty-six month period. Compensation expense is recognized on a straight-line basis over the vesting period. Shares are subject to certain restrictions and risk of forfeiture by the participants. As of June 30, 2013, unrecognized compensation expense was estimated to be $1.6 million for unvested restricted share awards.

Old National recorded expense of $0.4 million, net of tax, during the first six months of 2013, compared to expense of $0.1 million during the first six months of 2012 related to the vesting of restricted share awards. Included in the first six months of 2012 is the reversal of $0.4 million of expense associated with certain performance-based restricted stock grants.

In connection with the acquisition of Indiana Community Bancorp on September 15, 2012, 15 thousand unvested Indiana Community Bancorp restricted stock awards were converted to 29 thousand unvested Old National restricted stock awards. These restricted stock awards vested December 31, 2012 upon the retirement of the participant with the remaining expense of $23 thousand accelerated into the fourth quarter of 2012.

Restricted Stock Units

The Company granted 295 thousand shares of performance based restricted stock units to certain key officers during the first six months of 2013, with shares vesting at the end of a thirty-six month period based on the achievement of certain targets. For certain awards, the level of performance could increase or decrease the percentage of shares earned. Compensation expense is recognized on a straight-line basis over the vesting period. Shares are subject to certain restrictions and risk of forfeiture by the participants.

Old National recorded $1.0 million of stock based compensation expense, net of tax, during the first six months of 2013. Old National recorded $0.7 million of stock based compensation expense, net of tax, during the first six months of 2012. Included in the first six months of 2012 is the reversal of $20 thousand of expense associated with certain performance-based restricted stock grants.

Stock Options

Old National has not granted stock options since 2009. However, in connection with the acquisition of Indiana Community Bancorp on September 15, 2012, 0.2 million options for shares of Indiana Community Bancorp stock were converted to 0.3 million options for shares of Old National Bancorp stock. Old National recorded no incremental expense associated with the conversion of these options.

Old National did not record any stock based compensation expense related to stock options during the first six months of 2013. Old National recorded $6 thousand of stock based compensation expense, net of tax, during the first six months of 2012.

FEDERAL HOME LOAN BANK

Federal Home Loan Bank advances had weighted-average rates of 0.62% and 3.07% at June 30, 2013, and December 31, 2012, respectively. These borrowings are collateralized by investment securities and residential real estate loans up to 145% of outstanding debt.

In the first six months of 2013, Old National has terminated $50.0 million of Federal Home Loan Bank advances, resulting in a loss on extinguishment of debt of $1.0 million. Old National also restructured $33.4 million pertaining to two FHLB advances in the first quarter of 2013, which lowered their effective interest rates from 3.27% and 3.29% to 2.04% and 2.49%, respectively.

JUNIOR SUBORDINATED DEBENTURES

Junior subordinated debentures related to trust preferred securities are classified in “other borrowings”. These securities qualify as Tier 1 capital for regulatory purposes, subject to certain limitations.

In 2007, Old National acquired St. Joseph Capital Trust II in conjunction with its acquisition of St. Joseph Capital Corporation. Old National guarantees the payment of distributions on the trust preferred securities issued by St. Joseph Capital Trust II. St. Joseph Capital Trust II issued $5.0 million in preferred securities in March 2005. The preferred securities had a cumulative annual distribution rate of 6.27% until March 2010 and now carry a variable rate of interest priced at the three-month LIBOR plus 175 basis points, payable quarterly and maturing on March 17, 2035. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by St. Joseph Capital Trust II. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities.

In 2011, Old National acquired Monroe Bancorp Capital Trust I and Monroe Bancorp Statutory Trust II in conjunction with its acquisition of Monroe Bancorp. Old National guarantees the payment of distributions on the trust preferred securities issued by Monroe Bancorp Capital Trust I and Monroe Bancorp Statutory Trust II. Monroe Bancorp Capital Trust I issued $3.0 million in preferred securities in July 2006. The preferred securities carried a fixed rate of interest of 7.15% until October 7, 2011 and thereafter a variable rate of interest priced at the three-month LIBOR plus 160 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Monroe Bancorp Capital Trust I. Monroe Bancorp Statutory Trust II issued $5.0 million in preferred securities in March 2007. The preferred securities carried a fixed rate of interest of 6.52% until June 15, 2012 and thereafter a variable rate of interest priced at the three-month LIBOR plus 160 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Monroe Bancorp Statutory Trust II. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities in whole or in part.

In 2012, Old National acquired Home Federal Statutory Trust I in conjunction with its acquisition of Indiana Community Bancorp. Old National guarantees the payment of distributions on the trust preferred securities issued by Home Federal Statutory Trust I. Home Federal Statutory Trust I issued $15.0 million in preferred securities in September 2006. The preferred securities carry a variable rate of interest priced at the three-month LIBOR plus 165 basis points. Proceeds from the issuance of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by Home Federal Statutory Trust I. Old National, at any time, may redeem the junior subordinated debentures at par and thereby cause a redemption of the trust preferred securities in whole or in part.

CAPITAL LEASE OBLIGATION

On January 1, 2004, Old National entered into a long-term capital lease obligation for a branch office building in Owensboro, Kentucky, which extends for 25 years with one renewal option for 10 years. The economic substance of this lease is that Old National is financing the acquisition of the building through the lease and accordingly, the building is recorded as an asset and the lease is recorded as a liability. The fair value of the capital lease obligation was estimated using a discounted cash flow analysis based on Old National’s current incremental borrowing rate for similar types of borrowing arrangements.

At June 30, 2013, the future minimum lease payments under the capital lease were as follows:

Employee Benefit Plans

NOTE 14 – EMPLOYEE BENEFIT PLANS

RETIREMENT PLAN

Old National maintains a funded noncontributory defined benefit plan (the “Retirement Plan”) that was frozen as of December 31, 2005. Retirement benefits are based on years of service and compensation during the highest paid five years of employment. The freezing of the plan provides that future salary increases will not be considered. Old National’s policy is to contribute at least the minimum funding requirement determined by the plan’s actuary. Old National expects to contribute approximately $180 thousand to the Retirement Plan in 2013.

Old National also maintains an unfunded pension restoration plan (the “Restoration Plan”) which provides benefits for eligible employees that are in excess of the limits under Section 415 of the Internal Revenue Code of 1986, as amended, that apply to the Retirement Plan. The Restoration Plan is designed to comply with the requirements of ERISA. The entire cost of the plan, which was also frozen as of December 31, 2005, is supported by contributions from the Company.

Old National contributed $63 thousand to cover benefit payments from the Restoration Plan during the first six months of 2013. Old National expects to contribute an additional $60 thousand to cover benefit payments from the Restoration Plan during the remainder of 2013.

The net periodic benefit cost and its components were as follows for the three and six months ended June 30:

	Three Months Ended						Six Months Ended
	June 30,						June 30,
(dollars in thousands)	2013			2012			2013			2012

Recognized actuarial loss		580			1,007			1,159			2,013
Settlement		144			—			423			—
Net periodic benefit cost	$	608		$	913		$	1,351		$	1,826

On September 15, 2012, Old National assumed Indiana Bank and Trust’s Pentegra Defined Benefit Plan for Financial Institutions. This defined benefit pension plan has been frozen since April 1, 2008. The trustees of the Financial Institutions Retirement Fund administer the Pentegra Plan, employer identification number 13-5645888 and plan number 333. The Pentegra Plan operates as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code.

The Pentegra Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra Plan contributions made by a contributing employer may be used to provide benefits to participants of other participating employers. There is no separate valuation of the Pentegra Plan benefits or segregation of the Pentegra Plan assets specifically for a company, because the Pentegra Plan is a multi-employer plan and separate actuarial valuations are not made with respect to each employer. The funded status of the Pentegra Plan, or the market value of plan assets divided by funding target, as of July 1, 2012 and 2011 was 101.2% and 84.4%, respectively.

During the second quarter of 2013, Old National withdrew from the plan, contributing $14.0 million to satisfy the final termination liability. Funding the termination liability had no impact on earnings as it was considered in the fair value of Indiana Bank and Trust’s purchase accounting entries.
