Fair-Value Measurements [Abstract] |
Fair-Value Measurements | 13. Fair-Value Measurements In accordance with fair value reporting standards, we categorize our financial assets and liabilities in three general levels: Level 1 inputs are quoted prices in active markets for identical assets or liabilities; Level 2 inputs include data points that are observable, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) such as interest rates and yield curves that are observable for the asset and liability, either directly or indirectly; Level 3 inputs are unobservable data points for the asset or liability, and include situations in which there is little, if any, market activity for the asset or liability. As of December 31, 2012 and 2011, we had no Level 3 financial assets or liabilities. The following table presents the fair-value hierarchy for our Level 1 and 2 financial assets and liabilities measured at fair value on a recurring basis:
|  | Total fair value at |  | Quoted prices in active markets |  | Significant other observable inputs

During 2012 and 2011 there were no transfers between levels 1, 2, and 3. Cash equivalents include short-term securities that are considered to be highly liquid and easily tradable. These securities are valued using inputs observable in active markets for identical securities. The common stock of a foreign public company is traded in an active market exchange. The shares are measured at fair value using closing stock prices and are recorded in the Consolidated Balance Sheets as Other assets. The securities are classified as available for sale, and as a result any gain or loss is recorded in the Shareholders' Equity section of the Consolidated Balance Sheets rather than in the Consolidated Statements of Income. When the security is sold or impaired, gains and losses are reported on the Consolidated Statements of Income. Investments are considered to be impaired when a decline in fair value is judged to be other than temporary. Foreign currency instruments are entered into periodically, and consist of foreign currency option contracts or forward contracts that are valued using quoted prices in active markets obtained from independent pricing sources. These instruments are measured using market foreign exchange prices and are recorded in the Consolidated Balance Sheets as Other current assets. Changes in fair value of these instruments are recorded as gains or losses within Other (income)/expense, net. Gains totaled $0.0 million during 2012, and losses totaled $0.6 million during 2011. When exercised, the foreign currency instruments are net settled with the same financial institution that bought or sold them. For all positions, whether options or forward contracts, there is risk from the possible inability of the financial institution to meet the terms of the contracts and the risk of unfavorable changes in interest and currency rates, which may reduce the value of the instruments. We seek to control risk by evaluating the creditworthiness of counterparties and by monitoring the currency exchange and interest rate markets while reviewing the hedging risks and contracts to ensure compliance with our internal guidelines and policies. We operate our business in many regions of the world, and currency rate movements can have a significant effect on operating results. Changes in exchange rates can result in revaluation gains and losses that are recorded in Selling, General, Technical, Product Engineering, and Research expenses or Other income/expense, net. Revaluation gains and losses occur when our business units have intercompany or third-party trade receivable or payable balances in a currency other than their local reporting (or functional) currency. Operating results can also be affected by the translation of sales and costs, for each non-U.S. subsidiary, from the local functional currency to the U.S. dollar. The translation effect on the income statement is dependent on our net income or expense position in each non-U.S. currency in which we do business. A net income position exists when sales realized in a particular currency exceed expenses paid in that currency; a net expense position exists if the opposite is true. In order to mitigate foreign exchange volatility in the financial statements, we periodically enter into foreign currency financial instruments from time to time. There were no foreign currency financial instruments designated as hedging instruments at December 31, 2012. As described in Note 12 of the Notes to Consolidated Financial Statements, on July 16, 2010, we entered into a $390 million unsecured five-year revolving credit facility agreement. The applicable interest rate for borrowings under the agreement is LIBOR plus a spread, based on our leverage ratio at the time of borrowing. Interest rate changes on this variable rate debt cause changes in cash flows, and in order to mitigate this cash flow risk we have fixed a portion of the effective interest rate on part of the indebtedness drawn under the agreement by entering into interest rate hedging transactions on July 16, 2010. This interest rate swap locked in our interest rate on the forecasted outstanding borrowings of $105 million at 2.04% plus the credit spread on the debt for a five-year period. The credit spread is based on the pricing grid, which can go as low as 2.0% or as high as 2.75%, based on our leverage ratio. The interest rate swap is accounted for as a hedge of future cash flows. The fair value of our interest rate swap is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve, and is recorded in the Consolidated Balance Sheets as of December 31, 2012, as Other noncurrent liabilities of $4.7 million. Unrealized gains and losses on the swap will flow through the caption Derivative valuation adjustment in the Shareholders' equity section of the Consolidated Balance Sheets, to the extent that the hedge is highly effective. Gains and losses related to the ineffective portion of the hedge will be recognized in the current period in earnings. Amounts accumulated in Other comprehensive income are reclassified as Interest expense, net when the related interest payments (that is, the hedged forecasted transactions) affect earnings. Interest expense related to the swap totaled $1.7 million for 2012, and $1.9 million for 2011. Fair value amounts of derivative instruments were as follows:
