Other Matters	Other MattersOn September 27, 2022, Lakeland Bank (the "Bank"), a wholly-owned subsidiary of the Company, entered into a consent order with the U.S. Department of Justice (“DOJ”) to resolve allegations of violations of the Fair Housing Act and the Equal Credit Opportunity Act within the Newark, NJ-PA Metro Division, as constituted in 2015. The DOJ’s consent order requires the Bank, among other things, to invest $12 million over five years in a loan subsidy fund to increase credit opportunities to residents of majority-Black and Hispanic neighborhoods in Essex, Morris, Somerset, Sussex and Union Counties, New Jersey (the “Newark Lending Area”), and devote a minimum of $400,000 over five years towards community development partnership contributions in the Newark Lending Area and $150,000 per year over five years toward advertising, community outreach, and credit repair and education in the Newark Lending Area. Pursuant to the terms of the consent order, the Bank will also establish two new full-service branches in majority-Black and Hispanic census tracts: one in Newark, New Jersey and one in the Bank’s Newark Lending Area. In addition, the Bank must continue to maintain its full-time Community Development Officer position to oversee these efforts throughout the term of the consent order. On September 29, 2022, the DOJ consent order was approved by the United States District Court for the District of New Jersey resolving all claims by the DOJ against Lakeland Bank. The Company is committed to investing $12 million over five years and will record the related expenses in the period in which the activities occur.
