One-Year Outlook Summary Relative to 2Q14 Results Topic Outlook Comment Loan Balances Slightly to Moderately Increasing • Prepayments remain volatile, making net loan growth difficult to forecast • 3Q14 QTD (period-end) loans down moderately, including a managed decline in construction and land development loans, as well as a sale of approximately $30 million nonperforming loans, both of which are expected to enhance the company’s post-stress capital ratios for the 2015 CCAR exercise. Net Interest Income Stable • FDIC Covered Loan income likely to experience further decline • Excluding interest income from covered loans, NII likely moderately increasing, assuming moderate loan growth and debt reduction Provisions Moderately Negative • Includes Provisions for Loan Losses & Reserve for Unfunded Loan Commitment Fee Income Increasing • Excluding securities impairment charge, fee income initiatives likely to result in moderate increase Noninterest Expense Stable • Higher expenses stemming from loan/deposit/accounting systems upgrade, offset by reduced credit-related NIE and subsiding FDIC Indemnification Asset amortization 33
