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. On April 5, 2016, Old National entered into a settlement agreement with plaintiffs providing for a cash payment from Old National in the amount of $4,750,000 in exchange for a full release and dismissal of plaintiffs’ complaint. By entering into the settlement agreement, Old National did not admit any liability with respect to the lawsuit. The settlement amount was accrued for in the December 31, 2015 financial statements. On April 14, 2016, the Circuit Court preliminarily approved the settlement agreement, entered an order authorizing notice of the settlement to the class participants. On June 13, 2016, the Circuit Court entered its Final Judgment and Final Order approving the class action settlement and dismissed, in its entirety, the class action lawsuit against Old National with prejudice. No other material litigation is currently pending. 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. Old National had deferred gains remaining associated with prior sale leaseback transactions totaling $35.8 million as of June 30, 2016 and $40.7 million as of December 31, 2015. The gains are being recognized over the remaining term of the leases. The leases had original terms ranging from five to twenty-four years. New accounting guidance has been issued for leases, and it is probable that this accounting treatment will change in the future. 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 $2.251 billion and standby letters of credit of $61.6 million at June 30, 2016.
