Fair Value of Financial Instruments | Fair Value of Financial Instruments Recurring Fair Value Measurements The following tables represent the financial assets and (liabilities) measured at fair value on a recurring basis as of March 31, 2017 and March 31, 2016 and the basis for that measurement:

The fair values of lead forward contracts are calculated using observable prices for lead as quoted on the London Metal Exchange (“LME”) and, therefore, were classified as Level 2 within the fair value hierarchy as described in Note 1, Summary of Significant Accounting Policies. The fair values for foreign currency forward contracts are based upon current quoted market prices and are classified as Level 2 based on the nature of the underlying market in which these derivatives are traded. Financial Instruments The fair values of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate carrying value due to their short maturities. The fair value of the Company’s short-term debt and borrowings under the 2011 Credit Facility (as defined in Note 8), approximate their respective carrying value, as they are variable rate debt and the terms are comparable to market terms as of the balance sheet dates and are classified as Level 2. The Company's Notes, with an original face value of $300,000, were issued in April 2015. The fair value of these Notes represent the trading values based upon quoted market prices and are classified as Level 2. The Notes were trading at approximately 101% and 96% of face value on March 31, 2017 and March 31, 2016, respectively. The carrying amounts and estimated fair values of the Company’s derivatives and Notes at March 31, 2017 and 2016 were as follows:
|  | March 31, 2017 |  |  |  | March 31, 2016 |  |
|  | Carrying Amount |  |  |  | Fair Value |  |  |  | Carrying Amount |  |  |  | Fair Value |  |

Non-recurring fair value measurements The valuation of goodwill and other intangible assets is based on information and assumptions available to the Company at the time of acquisition, using income and market approaches to determine fair value. The Company tests goodwill and other intangible assets annually for impairment, or when indications of potential impairment exist (see Note 1). Goodwill is tested for impairment by determining the fair value of the Company’s reporting units. The unobservable inputs used to measure the fair value of the reporting units include projected growth rates, profitability, and the risk factor premium added to the discount rate. The remeasurement of goodwill is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed using company-specific information. The inputs used to measure the fair value of other intangible assets were largely unobservable and accordingly were also classified as Level 3. The fair value of trademarks, is based on an estimate of the royalties saved that would have been paid to a third party had the Company not owned the trademark. The fair value of other indefinite-lived intangibles was estimated using the income approach, based on cash flow projections of revenue growth rates, taking into consideration industry and market conditions. In connection with the annual impairment testing conducted as of January 2, 2017 for fiscal 2017, indefinite-lived trademarks associated with Purcell US and Purcell EMEA were recorded at fair value on a nonrecurring basis at $4,300 and $3,900, respectively, and the remeasurement resulted in an impairment charge of $700 and $1,100, respectively. In determining the fair value of these assets, the Company used royalty rates ranging between 1.3%-2.5% based on comparable market rates, and used discount rates ranging between 15.0%-17.0%. In connection with the annual impairment testing conducted as of December 28, 2015 for fiscal 2016, indefinite-lived trademarks associated with Purcell and Quallion/ABSL US were recorded at fair value on a nonrecurring basis at $10,000 and $990, respectively, and the remeasurement resulted in an aggregate impairment charge of $3,420. In determining the fair value of these assets, the Company used royalty rates ranging between 0.5%-2.5% based on comparable market rates, and used discount rates ranging between 16.0%-24.0%. These charges are included under the caption "Impairment of goodwill, indefinite-lived intangibles and fixed assets" in the Consolidated Statements of Income.
