Non-GAAP Financial Information
4
To supplement its consolidated financial statements presented in accordance with Generally Accepted
Accounting Principles (GAAP), the Corporation provides additional measures of operating results, net
income and earnings per share (EPS) adjusted to exclude certain costs, expenses, and gains and losses. 
The Corporation believes that these non-GAAP financial measures are appropriate to enhance the
understanding of its past performance as well as prospects for its future performance.  In the event of such a
disclosure or release, the Securities and Exchange Commission’s Regulation G requires: (i) the presentation
of the most directly comparable financial measure calculated and presented in accordance with GAAP and
(ii) a reconciliation of the differences between the non-GAAP financial measure presented and the most
directly comparable financial measure calculated and presented in accordance with GAAP.  The required
presentations and reconciliations are contained herein and can be found at our website,
www.fnbcorporation.com, under “Shareholder and Investor Relations” by clicking on “Non-GAAP
Reconciliation.”
The Appendix to this presentation contains non-GAAP financial measures used by the Corporation to provid
information useful to investors in understanding the Corporation's operating performance and trends, and
facilitate comparisons with the performance of the Corporation's peers.  While the Corporation believes that
these non-GAAP financial measures are useful in evaluating the Corporation, the information should be
considered supplemental in nature and not as a substitute for or superior to the relevant financial information
prepared in accordance with GAAP.  The non-GAAP financial measures used by the Corporation may differ
from the non-GAAP financial measures other financial institutions use to measure their results of operations.
This information should be reviewed in conjunction with the Corporation’s financial results disclosed on 
July 25, 2011 and in its periodic filings with the Securities and Exchange Commission.
