Summary of Significant Accounting Policies

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. In our opinion, the interim condensed consolidated financial statements reflect all adjustments necessary for a fair presentation of the results of operations and financial position for such periods. 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 2015 Annual Report on Form 10-K. Unless otherwise noted, the term “year” and references to a particular year pertain to our fiscal year, which begins on July 1 and ends on June 30; for example, 2016 refers to fiscal 2016, which is the period from July 1, 2015 to June 30, 2016.

Cash and Equivalents

We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The carrying amounts of our cash and equivalents, including money market funds and commercial paper, approximate fair value due to their short maturities and are considered level 1 investments, which have quoted market prices in active markets for identical assets. As a result of our cash management system, checks issued but not presented to the banks for payment may create negative book cash balances. When such negative balances exist, they are included in other accrued liabilities and reflected as a financing activity in the Condensed Consolidated Statements of Cash Flows.

Property, Plant and Equipment

Property, plant and equipment are stated at cost less accumulated depreciation, except for those acquired as part of a business combination, which are stated at fair value at the time of purchase. Purchases of property, plant and equipment included in accounts payable and excluded from the property additions and the change in accounts payable in the Condensed Consolidated Statements of Cash Flows were as follows:



	December 31,
	2015		2014
Construction in progress in accounts payable	$	476	$	1,055

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.

Basic and diluted net income per common share were calculated as follows:



	Three Months Ended December 31,						Six Months Ended December 31,
	2015			2014			2015			2014
Net income	$	34,511		$	32,954		$	62,139		$	55,715

Stock-settled stock appreciation rights	43			26			31			25

Significant Accounting Policies

There were no changes to our Significant Accounting Policies from those disclosed in our 2015 Annual Report on Form 10-K.

Recently Issued Accounting Standards

In July 2015, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance which requires entities to measure most inventory “at the lower of cost or net realizable value,” thereby simplifying current guidance. Under current guidance an entity must measure inventory at the lower of cost or market, where market is defined as one of three different measures, one of which is net realizable value. The guidance will be effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2016. We are currently evaluating this guidance, but do not believe it will have a material impact on our consolidated financial statements.

In May 2014, the FASB issued new accounting guidance for the recognition of revenue under the principle: “Recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” Following a one-year deferral of the effective date, the guidance will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 and will require either retrospective application to each prior period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. We are currently evaluating the impact of this guidance.

Recently Adopted Accounting Standards

In November 2015, the FASB issued new accounting guidance which requires deferred tax assets and liabilities, as well as any related valuation allowance, be classified as noncurrent on the balance sheet. As a result, each jurisdiction will only have one net noncurrent deferred tax asset or liability. This guidance may be applied on either a prospective or retrospective basis and is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. We are adopting this guidance effective December 31, 2015 using a retrospective basis of adoption. With the adoption, our net deferred tax liability for all periods presented in the Condensed Consolidated Balance Sheets has been classified as noncurrent. For June 30, 2015, the reclassification of $12.8 million of current deferred tax assets to noncurrent liabilities caused the Other Current Assets line to change from $20.5 million to $7.7 million and the Deferred Income Taxes line to change from $35.7 million to $22.9 million. As this guidance only relates to balance sheet classification, there was no statement of income impact.

In September 2015, the FASB issued new accounting guidance which allows entities to prospectively reflect adjustments made to provisional amounts recognized for a business combination during the measurement period. Under the current guidance these adjustments need to be reflected retrospectively as if the accounting had been completed at the acquisition date. The guidance will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 but can be adopted early if financial statements have not been issued. We adopted this guidance effective July 1, 2015, and it did not have a material impact on our consolidated financial statements.
