Commitments and Contingencies	NOTE 19 - 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 Circuit Court challenging our 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 treble damages, attorneys’ fees and costs pursuant to the Indiana Crime Victim’s Relief Act. 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. On June 11, 2013, Old National moved for summary judgment asserting the law as applied to the material facts not in dispute should result in judgment in favor of Old National. On September 16, 2013, a hearing was held on the summary judgment motion and the Motion was denied by the Circuit Court on April 14, 2014. Subsequently, Old National sought and was granted leave to appeal the denial of its Motion for Summary Judgment. On July 11, 2014, the Indiana Court of Appeals accepted the appeal and the parties fully briefed the matter as of February 23, 2015. On April 23, 2015, the Court of Appeals affirmed in part and reversed in part the Circuit Court’s denial of Old National’s Motion for Summary Judgment and remanded the case to the Circuit Court for further proceedings. Specifically, the Court of Appeals rejected Old National’s contention that all of plaintiffs’ claims were preempted by federal law but did agree that plaintiffs’ state law claims of conversion, unconscionability and unjust enrichment were unsupported under Indiana law. The dismissal of these claims remove any claims which would entitle plaintiffs to treble damages. The Court of Appeals determined Old National had not negated plaintiffs’ state law claim for breach of a duty of good faith and fair dealing as to the deposit account agreement and remanded that contractual claim back to the Circuit Court. Old National expects to file a Petition to Transfer the Case to the Indiana Supreme Court within the statutory timeframes. 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. Old National does not have any material sub-lease agreements. As of March 31, 2015 and December 31, 2014, Old National had $66.6 million and $68.3 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 $1.700 billion and standby letters of credit of $60.0 million at March 31, 2015. At March 31, 2015, approximately $1.619 billion of the loan commitments had fixed rates and $80.9 million had floating rates, with the floating interest rates ranging from 0% to 21%. At December 31, 2014, loan commitments were $1.584 billion and standby letters of credit were $65.3 million. These commitments are not reflected in the consolidated financial statements. At March 31, 2015 and December 31, 2014, the allowance for unfunded loan commitments totaled $2.8 million and $4.4 million, respectively. At March 31, 2015 and December 31, 2014, Old National had credit extensions of $16.0 million and $13.0 million, respectively, with various unaffiliated banks related to letter of credit commitments issued on behalf of Old National’s clients. At March 31, 2015 and December 31, 2014, Old National provided collateral to the unaffiliated banks to secure credit extensions totaling $14.5 million and $11.5 million, respectively. Old National did not provide collateral for the remaining credit extensions.

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.
