Segment Reporting [Abstract]

BUSINESS SEGMENTS

BUSINESS SEGMENTS

We operate in three reportable segments: Community Banking, Wealth Management and Insurance.

•The Community Banking segment provides commercial and consumer banking services. Commercial banking solutions include corporate banking, small business banking, investment real estate financing, business credit, capital markets and equipment financing. Consumer banking products and services include deposit products, mortgage lending, consumer lending and a complete suite of mobile and online banking services.

•The Wealth Management segment provides a broad range of personal and corporate fiduciary services including the administration of decedent and trust estates. In addition, it offers various alternative products, including securities brokerage (under a third-party arrangement) and investment advisory services, mutual funds and annuities.

•The Insurance segment includes a full-service insurance brokerage service offering all lines of commercial and personal insurance through major carriers. The Insurance segment also includes a reinsurer.

Our Chief Operating Decision Maker (CODM) is our Chief Executive Officer. The CODM uses net interest income contributions, non-interest income, salary and employee benefits and net income for each segment predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis for these measures when making decisions about the allocation of operating and capital resources to each segment. The CODM also uses segment income contributions for evaluating pricing strategies and segment operating income to assess the performance of each segment by comparing the results of each segment with one another and in determining the compensation of certain employees.

The following table provides financial information for these segments of FNB. The information provided under the caption “Parent and Other” represents operations not considered to be reportable segments and/or general operating expenses of FNB, and includes the parent company, other non-bank subsidiaries and eliminations and adjustments to reconcile to the Consolidated Financial Statements.
