Estimates
Estimates
In preparing the consolidated financial statements in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X, management must make estimates and assumptions. These estimates and assumptions affect the amounts reported for assets, liabilities, revenues and expenses, as well as affecting the disclosures provided. Examples of estimates include the allowance for doubtful accounts, estimates of deferred income tax assets and liabilities, estimates of inventory balances, and estimates of stock option values. The Company also uses estimates when assessing fair values of assets and liabilities acquired in business acquisitions as well as any fair value and any related impairment charges related to the carrying value of inventory and machinery and equipment and other long-lived assets. Despite the Company’s intention to establish accurate estimates and use reasonable assumptions, actual results may differ from these estimates.
Reclassifications
Reclassifications
We have reclassified certain income statement and balance sheet items within the accompanying Condensed Consolidated Financial Statements and Notes to Condensed Consolidated Financial Statements for the prior year in order to be comparable with the current presentation. These reclassifications had no effect on previously reported income (loss) or shareholders' equity.
Fair Value
Fair Value
We carry certain of our financial assets and liabilities at fair value on a recurring basis. These financial assets and liabilities are composed of cash and cash equivalents and derivative instruments. Long-term debt is carried at cost, and the fair value is disclosed herein. In addition, we measure certain assets, such as long-lived assets, at fair value on a non-recurring basis to evaluate those assets for potential impairment. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
In accordance with applicable accounting standards, we categorize our financial assets and liabilities into the following fair value hierarchy:
Level 1 – Financial assets and liabilities with values based on unadjusted quoted prices for identical assets or liabilities in an active market. Examples of level 1 financial instruments include active exchange-traded securities.
Level 2 – Financial assets and liabilities with values based on quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. Examples of level 2 financial instruments include commercial paper purchased from the State Street-administered asset-backed commercial paper conduits, various types of interest-rate and commodity-based derivative instruments, and various types of fixed-income investment securities. Pricing models are utilized to estimate fair value for certain financial assets and liabilities categorized in level 2.
Level 3 – Financial assets and liabilities with values based on prices or valuation techniques that require inputs that are both unobservable in the market and significant to the overall fair value measurement. These inputs reflect management’s judgment about the assumptions that a market participant would use in pricing the asset or liability, and are based on the best available information, some of which is internally developed. Examples of level 3 financial instruments include certain corporate debt with little or no market activity and a resulting lack of price transparency.
When determining the fair value measurements for financial assets and liabilities carried at fair value on a recurring basis, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability. When possible, we look to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, we look to market observable data for similar assets and liabilities. Nevertheless, certain assets and liabilities are not actively traded in observable markets, and we use alternative valuation techniques to derive fair value measurements.
We use the fair value methodology outlined in the related accounting standards to value the assets and liabilities for cash, debt and derivatives. All of our cash is defined as Level 1 and all our debt and derivative contracts are defined as Level 2.
Stock Option Plan
Stock Option Plan
We provide compensation benefits by granting stock options to employees and directors. The exercise price of each option is equal to the market price of our stock on the date of grant. The maximum term of the option is 5 years. We recognize share-based compensation expense for the fair value of the awards, as estimated using the Modified Black-Scholes-Merton Model, on the date granted on a straight-line basis over their vesting term. Compensation expense is recognized only for share-based payments expected to vest. We estimate forfeitures at the date of grant based on our historical experience and future expectations.

There are two significant inputs into the Black-Scholes option pricing model: expected volatility and expected term. We estimate expected volatility based on traded option volatility of our stock over a term equal to the expected term of the option granted. The expected term of stock option awards granted is derived from historical exercise experience under the our long-term incentive plan and represents the period of time that stock option awards granted are expected to be outstanding. The assumptions used in calculating the fair value of stock-based payment awards represent management's best estimates, but these estimates involve inherent uncertainties and the application of management's judgment. As a result, if factors change and we use different assumptions, stock-based compensation expense could be materially different in the future. In addition, we are required to estimate the expected forfeiture rate, and only recognize expense for those shares expected to vest. If our actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly different from what we have recorded in the current period.
The Company uses the Modified Black-Scholes-Merton option-pricing model to value the Company's stock options for each stock option award. Using this option-pricing model, the fair value of each stock option award is estimated on the date of grant. The fair value of the Company's stock option awards, which are generally subject to pro-rata vesting annually over one year, is expensed on a straight-line basis over the vesting period of the stock options. The expected volatility assumption is based on traded options volatility of the Company's stock over a term equal to the expected term of the option granted. The expected term of stock option awards granted is derived from historical exercise experience under the Company's stock option plans and represents the period of time that stock option awards granted are expected to be outstanding. The expected term assumption incorporates the contractual term of an option grant, which is five years, as well as the vesting period of an award, which is generally pro-rata vesting annually over one year. The risk-free interest rate is based on the implied yield on a U.S. Treasury constant maturity with a remaining term equal to the expected term of the option granted.

The Company recognizes stock-based compensation costs, net of estimated forfeitures, for only those shares expected to vest on a straight-line basis over the requisite service period of the award. The Company estimates the forfeiture rates based on its historical experience. Treasury shares are issued for exercised options.
