Fair Value Of Financial Instruments

Fair Value Of Financial Instruments

4. Fair Value Of Financial Instruments

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. The Company uses the following valuation techniques to measure fair value for its financial assets and financial liabilities:


Level 1		Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2		Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

Level 3		Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The following tables represent the financial assets and (liabilities), measured at fair value on a recurring basis as of July 3, 2011 and March 31, 2011 and the basis for that measurement:


	Total Fair Value Measurement July 3, 2011			Quoted Price in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Interest rate swap agreements	$	(6,175	)	$	—	$	(6,175	)	$	—
Lead forward contracts		4,891			—		4,891			—
Foreign currency forward contracts		(1,194	)		—		(1,194	)		—

Total derivatives	$	(2,478	)	$	—	$	(2,478	)	$	—


	Total Fair Value Measurement March 31, 2011			Quoted Price in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Interest rate swap agreements	$	(5,847	)	$	—	$	(5,847	)	$	—
Lead forward contracts		9,575			—		9,575			—
Foreign currency forward contracts		(2,591	)		—		(2,591	)		—

Total derivatives	$	1,137		$	—	$	1,137		$	—

The fair value of interest rate swap agreements are based on observable prices as quoted for receiving the variable three month LIBOR and paying fixed interest rates and, therefore, were classified as Level 2.

The fair value 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.

The fair value 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 value 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 $350 million 2011 senior secured revolving credit facility ("2011 Credit Facility"), the 75.0 million Chinese renminbi (RMB) ($11.5 million) credit facility ("China Term Loan"), and short-term debt approximate their carrying value, as they are variable rate debt and the current terms are comparable to market terms as of the balance sheet dates.

The Convertible Notes, with a face value of $172,500, were issued when the Company's stock price was trading at $30.19 per share. On July 3, 2011, the Company's stock price closed at $35.21 per share. The Convertible Notes have a conversion option at $40.60 per share, and due to current conditions in the financial markets, the Company's Convertible Notes were trading at 114% of face value on July 3, 2011, and 125% of face value on March 31, 2011. As of July 3, 2011 and March 31, 2011, the unamortized discount on the Convertible Notes was $29,105 and $30,663, respectively.

The carrying amounts and estimated fair values of the Company's derivatives and Convertible Notes at July 3, 2011 and March 31, 2011 were as follows:


	July 3, 2011						March 31, 2011

Represents interest rate swap agreements, lead and foreign currency hedges (see Note 5 for asset and liability positions of the interest rate swap agreements, lead and foreign currency hedges at July 3, 2011 and March 31, 2011).

⁽²⁾

The carrying amounts of the Convertible Notes at July 3, 2011 and March 31, 2011 represent the $172,500 principal value, less the unamortized debt discount (see Note 10).

⁽³⁾

The fair value amounts of the Convertible Notes represent the trading values of the Convertible Notes with a principal value of $172,500 at July 3, 2011 and March 31, 2011.

Derivative Financial Instruments

Derivative Financial Instruments

5. Derivative Financial Instruments

The Company utilizes derivative instruments to reduce its exposure to interest rate, commodity price and foreign exchange risks under established procedures and controls. The Company does not enter into derivative contracts for speculative purposes. The Company's agreements are with creditworthy financial institutions and the Company anticipates performance by counterparties to these contracts and therefore no material loss is expected.

Interest Rate Swap Agreements

As of July 3, 2011 and March 31, 2011, the Company maintained interest rate swap agreements that converted $85,000 of variable-rate debt to a fixed-rate basis, utilizing the three-month London Interbank Offered Rate, or LIBOR as a floating rate reference. These agreements, which expire between February 2013 and May 2013, no longer qualified for hedge accounting at the end of fiscal 2011 as a result of the refinancing of the Company's previous credit facility. Changes in the fair value of these agreements during the first quarter of fiscal 2012 have been recorded in the income statement in other (income) expense, net. Such charges amounted to $710 for the first quarter of fiscal 2012. In the comparable period of fiscal 2011, the Company recorded a loss of $1,975 on the interest rate swaps that was recorded as an increase to interest expense.

Lead Hedge Contracts

The Company enters into lead hedge contracts to fix the price for lead purchases. Management considers the lead hedge contracts to be effective against changes in the cash flows of the underlying lead purchases based on the criteria under FASB guidance. The vast majority of such contracts are for a period not extending beyond one year.

Foreign Currency Forward Contracts

On a selective basis the Company will enter into foreign currency forward contracts and option contracts to reduce the volatility from currency movements that affect the Company. Each contract is for a period not extending beyond one year.

As of July 3, 2011 and March 31, 2011, the Company had entered into a total of $87,396 and $82,829, respectively, foreign currency forward contracts.

In the coming twelve months, the Company anticipates that $6,847 of the current pretax gain will be reclassified from AOCI as part of cost of goods sold. This amount represents the current unrealized impact of hedging lead and foreign exchange rates, which will change as market rates change in the future, and will ultimately be realized in the income statement as an offset to the corresponding actual changes in lead costs to be realized in connection with the variable lead cost and foreign exchange rates being hedged.

Presented below in tabular form is information on the location and amounts of derivative fair values in the Consolidated Condensed Balance Sheets and derivative gains and losses in the Consolidated Condensed Statements of Income:

Income Taxes
Income Taxes	6. Income Taxes The Company's income tax provisions for all periods consist of federal, state and foreign income taxes. The tax provisions for the first quarters of fiscal 2012 and 2011 were based on the estimated effective tax rates applicable for the full years ending March 31, 2012 and March 31, 2011, respectively, after giving effect to items specifically related to the interim periods. The effective income tax rates for the first quarters of fiscal 2012 and 2011 were 24.0% and 27.0%, respectively. The rate decrease in the first quarter of fiscal 2012 as compared to the comparable prior year period is primarily due to changes in the mix of earnings among tax jurisdictions.

8. Commitments, Contingencies And Litigation

Litigation and Other Legal Matters

The Company is involved in litigation incidental to the conduct of its business, the results of which, in the opinion of management, are not likely to be material to the Company's financial condition, results of operations, or cash flows (see Note 19 to the Consolidated Financial Statements included in the Company's 2011 Annual Report on Form 10-K).

Environmental Issues

As a result of its operations, the Company is subject to various federal, state, and local, as well as international environmental laws and regulations and is exposed to the costs and risks of handling, processing, storing, transporting, and disposing of hazardous substances, especially lead and acid. The Company's operations are also subject to federal, state, local and international occupational safety and health regulations, including laws and regulations relating to exposure to lead in the workplace.

As more fully described in Note 19 to the Consolidated Financial Statements included in the Company's 2011 Annual Report on Form 10-K, the Company has potential environmental liabilities at its Sumter, South Carolina facility and has reserves of $3,184 at July 3, 2011, and $3,279 at March 31, 2011. Based on information available at this time, management believes that the Company's reserves are sufficient to satisfy its environmental liabilities.

Lead Contracts

To stabilize its costs, the Company has entered into contracts with financial institutions to fix the price of lead. The vast majority of such contracts are for a period not extending beyond one year. Under these contracts, at July 3, 2011 and March 31, 2011, the Company has hedged the price to purchase 31,039 and 63,396 pounds of lead, respectively, for a total purchase price of $32,782 and $68,212, respectively.

Foreign Currency Forward Contracts

The Company quantifies and monitors its global foreign currency exposures. On a selective basis, the Company will enter into foreign currency forward and option contracts to reduce the volatility from currency movements that affect the Company. The maturity period of these contracts is less than one year. The Company's largest exposure is from the purchase and conversion of U.S. dollar based lead costs into local currencies in Europe. Additionally, the Company has currency exposures from intercompany and third party trade transactions. To hedge these exposures, the Company has entered into a total of $87,396 and $82,829, respectively, of foreign currency forward contracts with financial institutions as of July 3, 2011 and March 31, 2011.

Interest Rate Swap Agreements

The Company is exposed to changes in variable U.S. interest rates on borrowings under its credit agreements. On a selective basis, from time to time, the Company enters into interest rate swap agreements to reduce the negative impact that increases in interest rates could have on its outstanding variable rate debt. At July 3, 2011 and March 31, 2011, such agreements which expire between February 2013 and May 2013, converted $85,000 of variable-rate debt to a fixed-rate basis, utilizing the three-month LIBOR, as a floating rate reference. Fluctuations in LIBOR and fixed rates affect both the Company's net financial investment position and the amount of cash to be paid or received under these agreements.

- Definition

The entire disclosure for commitments and contingencies.

Restructuring Plans

Restructuring Plans

9. Restructuring Plans

The Company has acquisition related restructuring plans and non-acquisition related restructuring plans and bases its restructuring accounting and disclosures on the applicable accounting guidance. As a result, charges to net earnings were made in the periods in which restructuring plan liabilities were incurred.

Acquisition related restructuring plan

In fiscal 2010, the Company acquired the stock of OEB Traction Batteries and certain operating assets and liabilities of the reserve power battery business of Accu Holding AG and its Swedish sales subsidiary (all collectively referred to as "Oerlikon"). The Company completed the process of closing the two manufacturing facilities of Oerlikon during the third quarter of fiscal 2011 which resulted in the reduction of approximately 105 employees. Based on commitments incurred to date, the Company recorded $3,815 in fiscal 2010 and 2011 in charges relating to this plan and $499 during the first quarter of fiscal 2012. As of July 3, 2011, the reserve balance associated with these actions is $303. The Company expects to finalize the plan with an additional $300 of restructuring charges in fiscal 2012 in Europe.

A roll-forward of the acquisition related restructuring reserve is as follows:


	Employee Severance			Plant Closure and Other			Total
Balance at March 31, 2011	$	257		$	146		$	403
Accrued		32			467			499
Costs incurred		(159	)		(469	)		(628	)
Foreign currency impact and other		18			11			29

Balance at July 3, 2011	$	148		$	155		$	303

Non-acquisition related restructuring plans

In February and May 2009, the Company announced a plan to restructure certain of its European and American operations, which will result in a reduction of approximately 515 employees upon completion across its operations. These actions are primarily in Europe, the most significant of which was the closure of its leased Italian manufacturing facility and the opening of a new Italian distribution center. The Company estimates that the total charges for these actions will amount to approximately $33,000, which includes cash expenses of approximately $24,000, primarily for employee severance-related payments, and a non-cash charge of approximately $9,000, primarily for impairment of fixed assets.

Based on commitments incurred to date, the Company recorded restructuring charges of $31,894 in fiscal 2009 through fiscal 2011, with $97 of additional charges during the first quarter of fiscal 2012. The Company incurred $5,629 of costs against the accrual during fiscal 2011, with an additional $1,873 of costs incurred during the first quarter of fiscal 2012. As of July 3, 2011, the reserve balance associated with these actions is $641. The Company expects to be committed to an additional $600 of restructuring charges in fiscal 2012 related to these actions.

During fiscal 2011, the Company announced a further restructuring of its European operations, which will result in the reduction of approximately 66 employees upon completion across its operations. The Company estimates that the total charges for these actions will amount to approximately $5,200, primarily from cash expenses for employee severance-related payments and site closure costs.

Based on commitments incurred to date, the Company recorded restructuring charges of $3,830 in fiscal 2011, with $249 of additional charges, offset by a favorable accrual adjustment of $435 related to the fiscal 2011 plan recorded in the first quarter of fiscal 2012. The Company incurred $1,316 of costs against the accrual during fiscal 2011, with an additional $722 of costs incurred during the first quarter of fiscal 2012. As of July 3, 2011, the reserve balance associated with these actions is $1,639. The Company expects to be committed to an additional $1,000 of restructuring charges in fiscal 2012 related to these actions.

A roll-forward of the non-acquisition related restructuring reserve is as follows:


	Employee Severance			Plant Closure and Other		Total
Balance at March 31, 2011	$	4,920		$	—	$	4,920
Accrual adjustment – Fiscal 2011 plan		(435	)				(435	)
Accrued		346			—		346
Costs incurred		(2,595	)		—		(2,595	)
Foreign currency impact and other		44			—		44

Balance at July 3, 2011	$	2,280		$	—	$	2,280

- Definition

2011 Senior Secured Revolving Credit Facility

On March 29, 2011, the Company entered into a new $350,000 senior secured revolving credit facility ("2011 Credit Facility"). At the time of closing, the Company borrowed $100,000 and used $88,400 of its available cash to repay and extinguish the existing Term A Loan and replace the existing undrawn $125,000 revolving credit facility, which comprised the 2008 Credit Facility. The 2011 Credit Facility matures on March 31, 2016. This facility includes an early termination provision under which the Company is required to meet a liquidity test in February 2015 related to its capacity to meet certain potential obligations related to the Convertible Notes in June 2015. Borrowings under the 2011 Credit Facility bear interest at a floating rate based, at the Company's option, upon (i) LIBOR plus an applicable percentage (currently 1.50%), (ii) the greater of the Federal Funds rate plus 0.50% or the prime rate, or one-month LIBOR plus 1.0%, plus an applicable percentage (currently 0.50%). There are no prepayment penalties on loans under the 2011 Credit Facility. The interest rate at July 3, 2011 was 1.76% and was 3.75% at March 31, 2011.

Obligations under the 2011 Credit Facility are secured by substantially all of the Company's existing and future acquired assets, including substantially all of the capital stock of the Company's United States subsidiaries that are guarantors under the new credit facility, and 65% of the capital stock of certain of the Company's foreign subsidiaries that are owned by the Company's United States companies.

China Term Loan

During the fourth quarter of fiscal 2011, the Company completed the financing of a 75,000 Chinese Renminbi (RMB) ($11,500) credit facility ("China Term Loan"). This is a six year term loan to provide a portion of the capital requirements for the Company's operations in China. At July 3, 2011 and March 31, 2011, the Company had drawn RMB 40,000 ($6,186) and RMB 40,000 ($6,112), respectively. This term loan currently bears interest at a rate of 7.26% per annum, adjusted annually, based on the official Peoples Bank of China Bank Rate and is payable in quarterly installments of RMB 2,000 ($309) commencing in April 2012.

Senior Unsecured 3.375% Convertible Notes

On May 28, 2008, the Company completed a registered offering of $172,500 aggregate principal amount of senior unsecured 3.375% Convertible Notes Due 2038 ("Convertible Notes"). The Convertible Notes are general senior unsecured obligations and rank equally with the Company's existing and future senior unsecured obligations and are junior to any of the Company's future secured obligations to the extent of the value of the collateral securing such obligations. The Convertible Notes are not guaranteed, and are structurally subordinate in right of payment to, all of the (i) existing and future indebtedness and other liabilities of the Company's subsidiaries and (ii) preferred stock of the Company's subsidiaries to the extent of their respective liquidation preferences.

The Convertible Notes require the semi-annual payment of interest in arrears on June 1 and December 1 of each year beginning December 1, 2008, at 3.375% per annum on the principal amount outstanding. The Convertible Notes will accrete principal beginning on June 1, 2015 and will bear contingent interest, if any, beginning with the six-month interest period commencing on June 1, 2015 under certain circumstances. The Convertible Notes will mature on June 1, 2038. Prior to maturity the holders may convert their Convertible Notes into shares of the Company's common stock at any time after March 1, 2015 or prior to that date under certain circumstances. When issued, the initial conversion rate was 24.6305 shares per $1,000 principal amount of Convertible Notes, which was equivalent to an initial conversion price of $40.60 per share.

At any time after June 6, 2015, the Company may at its option redeem the Convertible Notes, in whole or in part, for cash, at a redemption price equal to 100% of the accreted principal amount of Convertible Notes to be redeemed, plus any accrued and unpaid interest. A holder of Convertible Notes may require the Company to repurchase some or all of the holder's Convertible Notes for cash upon the occurrence of a fundamental change as defined in the indenture and on each of June 1, 2015, 2018, 2023, 2028 and 2033 at a price equal to 100% of the accreted principal amount of the Convertible Notes being repurchased, plus accrued and unpaid interest, if any, in each case. It is the Company's current intent to settle the principal amount of any conversions in cash, and any additional conversion consideration in cash, shares of EnerSys common stock or a combination of cash and shares. The Convertible Notes will mature on June 1, 2038, unless earlier converted, redeemed or repurchased.

If applicable, the Company will pay a make-whole premium on Convertible Notes converted in connection with certain fundamental changes that occur prior to June 6, 2015. The amount of the make-whole premium, if any, will be based on the Company's stock price and the effective date of the fundamental change. The indenture contains a detailed description of how the make-whole premium will be determined and a table showing the make-whole premium that would apply at various stock prices. No make-whole premium would be paid if the price of the Common Stock on the effective date of the fundamental change is less than $29.00. Any make-whole premium will be payable in shares of Common Stock (or the consideration into which the Company's Common Stock has been exchanged in the fundamental change) on the conversion date for the Convertible Notes converted in connection with the fundamental change.

The Convertible Notes are represented by a liability component which is reported herein as long-term debt, net of discount and an equity component representing the convertible feature which is included in additional paid-in-capital in EnerSys stockholders' equity.

The following represents the principal amount of the liability component, the unamortized discount, and the net carrying amount of our Convertible Notes as of July 3, 2011 and March 31, 2011, respectively:


	July 3,			March 31,
	2011			2011
Principal	$	172,500		$	172,500
Unamortized discount		(29,105	)		(30,663	)

Net carrying amount	$	143,395		$	141,837

Carrying amount of equity component	$	29,850		$	29,850

As of July 3, 2011, the remaining discount will be amortized over a period of 47 months. The conversion price of the $172,500 in aggregate principal amount of the Convertible Notes is $40.60 per share and the number of shares on which the aggregate consideration to be delivered upon conversion is 4,248,761.

The effective interest rate on the liability component of the Convertible Notes was 8.50%. The amount of interest cost recognized for the amortization of the discount on the liability component of the Convertible Notes was $1,558 and $1,434, respectively, during the quarters ended July 3, 2011 and July 4, 2010.

Stock-Based Compensation

Stock-Based Compensation

Stock-Based Compensation

12. Stock -Based Compensation

As of July 3, 2011, the Company maintains the EnerSys 2010 Equity Incentive Plan ("2010 EIP") for the grant of various types of equity awards including nonqualified stock options, restricted stock, restricted stock units, market share units and other forms of equity-based compensation. As of July 3, 2011, the Company had 2,912,575 shares available for future grants.

The Company recognized equity-based compensation expense associated with its equity incentive plans of $2,718, with a related tax benefit of $653, for the first quarter of fiscal 2012, and $2,110 with a related tax benefit of $570, for the first quarter of fiscal 2011.

Common stock activity for the first quarter of fiscal 2012 included the exercise of 79,800 options and the vesting of 243,676 restricted stock units and for the comparable period in fiscal 2011 included the exercise of 459,639 options and the vesting of 166,968 of restricted stock units. Net cash (paid) received, reflecting the cost of equity awards surrendered for option price and withholding taxes were ($763) and $3,526, respectively, for the first quarter of fiscal 2012 and 2011.

Stock Incentive Plans

Non-qualified stock options have been granted to employees under the equity incentive plan at prices not less than the fair market value of the shares on the dates the options were granted. Stock options issued prior to fiscal 2009 vest and become exercisable 25% per year over a four-year period from the date of grant. Stock options issued in fiscal 2009 and 2010 generally vest and become exercisable 33.3% per year over a three-year period from the date of grant. No stock options were granted during fiscal 2011 and the first quarter of fiscal 2012. Stock options generally expire 10 years from the date of grant. As of July 3, 2011 and March 31, 2011, there were 780,979 and 860,779, respectively, of non-qualified stock options outstanding.

Restricted Stock Units and Market Share Units

In May 2011, the Company granted to management and other key employees 96,840 restricted stock units, and 224,397 market share units. In May 2010, the Company granted to management and other key employees 287,212 restricted stock units and 124,093 market share units.

Restricted stock units are granted at the fair market value of the Company's common stock on the date of grant and vest and are settled in common stock 25% per year over a four-year period from the date of grant.

Market share units are granted at fair value on the date of grant and vest and are settled in common stock on the third anniversary of the date of grant. Market share units are converted into between zero and two shares of common stock for each unit granted at the end of a three-year performance cycle. The conversion ratio is calculated by dividing the average closing share price of the Company's common stock during the ninety calendar days immediately preceding the vesting date by the average closing share price of the Company's common stock during the ninety calendar days immediately preceding the grant date, with the resulting quotient capped at two. This quotient is then multiplied by the number of market share units granted to yield the number of shares of common stock to be delivered on the vesting date.

The compensation cost related to restricted stock units and market share units is based on the fair value at the grant date. The fair value of the restricted stock units granted in fiscal 2012 was based on the market price of $35.79 per share at the date of grant. The fair value of the market share units granted in the first quarter of fiscal 2012 was estimated at the date of grant at $48.36 per share using a binomial matrix-pricing model with the following assumptions: a risk-free interest rate of 0.93%, dividend yield of zero, time to maturity of 3 years and expected volatility of 45.5%. The fair value of the restricted stock units granted in fiscal 2011 was based on the market price of $25.67 per share at the date of grant. The fair value of the market share units granted in the first quarter of fiscal 2011 was estimated at the date of grant at $34.45 per share using a binomial matrix-pricing model with the following assumptions: a risk-free interest rate of 1.30%, dividend yield of zero, time to maturity of 3 years and expected volatility of 43.0%.

As of July 3, 2011, there were 593,921 restricted stock units and 348,490 market share units outstanding. At March 31, 2011, there were 741,299 restricted stock units and 124,093 market share units outstanding.

- Definition

Earnings Per Share

Earnings Per Share

14. Earnings Per Share

Net earnings per common share—basic is based on the weighted average number of shares of the Company's common stock outstanding. Net earnings per common share—diluted gives effect to all potentially dilutive common shares that were outstanding during the period. As of July 3, 2011 and July 4, 2010, the Company had outstanding stock options, market share units and restricted stock units that could potentially dilute basic earnings per share in the future. Weighted average common shares—basic and common shares—diluted were as follows:


	Quarter ended
	July 3, 2011		July 4, 2010
Weighted average shares of common stock outstanding—basic		50,052,627		48,819,481
Assumed exercise and lapse of equity awards, net of shares assumed reacquired		615,649		623,434

Weighted average common shares—diluted		50,668,276		49,442,915

Anti-dilutive equity awards not included in weighted average common shares—diluted		317,435		346,521

The aggregate number of common shares that the Company could be obligated to issue upon conversion of its Convertible Notes that the Company sold in May 2008, is 4,248,761. It is the Company's current intent to settle the principal amount of any conversions in cash, and any additional conversion consideration in cash, shares of the Company's common stock or a combination of cash and shares. No contingent shares were included in diluted shares outstanding during the first quarter of fiscal 2012 and 2011, as the specified conversion price exceeded the average market price of the Company's common stock, and the inclusion of contingent shares would have been anti-dilutive.
