Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and SEC Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.

All such adjustments reflected in the interim condensed consolidated financial statements are considered to be of a normal recurring nature. The results of operations for any interim period are not necessarily indicative of results for the full year. Accordingly, these financial statements should be read in conjunction with the financial statements and notes thereto contained in our 2013 Annual Report on Form 10-K.

Earnings Per Share

Earnings per share (“EPS”) is computed based on the weighted average number of shares of common stock and common stock equivalents (restricted stock and stock-settled stock appreciation rights) outstanding during each period. Unvested shares of restricted stock granted to employees are considered participating securities since employees receive nonforfeitable dividends prior to vesting and, therefore, are included in the earnings allocation in computing EPS under the two-class method. Basic EPS excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing income available to common shareholders by the diluted weighted average number of common shares outstanding during the period, which includes the dilutive potential common shares associated with nonparticipating restricted stock and stock-settled stock appreciation rights.

Long-Term Debt

At September 30, 2013 and June 30, 2013, we had an unsecured credit agreement under which we may borrow, on a revolving credit basis, up to a maximum of $120 million at any one time, with potential to expand the total credit availability to $200 million based on obtaining consent of the issuing banks and certain other conditions.
