NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2012

(Unaudited)

1. BASIS OF PRESENTATION

The accompanying (a) condensed consolidated balance sheet of Regal Beloit Corporation (the “Company”) as of December 31, 2011, which has been derived from audited financial statements, and (b) unaudited interim condensed consolidated financial statements as of June 30, 2012 and for the three and six months endedJune 30, 2012 and July 2, 2011, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s 2011 Annual Report on Form 10-K filed on February 29, 2012.

In the opinion of management, all adjustments considered necessary for a fair presentation of financial results have been made. Except as otherwise discussed, such adjustments consist of only those of a normal recurring nature. Operating results for the three and six months endedJune 30, 2012 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 29, 2012.

The Company operates on a 52/53 week fiscal year ending on the Saturday closest to December 31.

On January 1, 2012, the Company adopted new guidance which changes the presentation of comprehensive income. Under the new guidance, the Company has reported a separate Condensed Consolidated Statement of Comprehensive Income for all periods presented.

On January 1, 2012, the Company adopted new guidance which provides an option to first assess qualitative factors in determining whether is is more likely than not that the fair value of a reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company will perform its annual goodwill impairment test in the fourth quarter and does not expect the adoption of the guidance to have a material impact on its consolidated financial statements.

2. OTHER FINANCIAL INFORMATION

7. GOODWILL AND OTHER INTANGIBLES

Goodwill

As required, the Company performs an annual impairment test of goodwill during the fourth quarter or more frequently if events or circumstances change that would more likely than not reduce the fair value of its reporting units below their carrying value.

At June 30, 2012, most of the Company’s goodwill is attributable to the Electrical segment and the Company believes that substantially all of the goodwill is deductible for tax purposes. The following information presents changes to goodwill during the periods indicated (in millions):

2012	$	44.1
2013	43.4
2014	42.2
2015	34.6
2016	30.8

Amortization expense recorded for the three and six months ended June 30, 2012 was $10.9 million and $21.7 million respectively. Amortization expense recorded for the three and six months ended July 2, 2011 was $7.3 million and $14.4 million, respectively.

In-process research and development projects are estimated to be completed by the end of 2013 and amortization will begin upon project completion.

8. DEBT AND BANK CREDIT FACILITIES

The Company’s indebtedness as of June 30, 2012 and December 31, 2011 was as follows (in millions):

	June 30, 2012			December 31, 2011
Senior notes	$	750.0		$	750.0
Term loan	145.0			145.0
Revolving credit facility	—			9.0
Other	15.9			15.2
	910.9			919.2
Less: Current maturities	(11.1		)	(10.0		)
Non-current portion	$	899.8		$	909.2

At June 30, 2012, the Company had $750.0 millionof senior notes (the “Notes”) outstanding. Details on the senior notes are (in millions):

	Principal		Interest Rate	Maturity
Floating Rate Series 2007A	$	150.0	Floating (1)	August 2014
Floating Rate Series 2007A	100.0		Floating (1)	August 2017
Fixed Rate Series 2011A	100.0		4.1%	July 2018
Fixed Rate Series 2011A	230.0		4.8 to 5.0%	July 2021
Fixed Rate Series 2011A	170.0		4.9 to 5.1%	July 2023
	$	750.0

(1) Interest rates vary as LIBOR varies. At June 30, 2012, the interest rate was between1.1% and 1.2%.

In 2008, the Company entered into a Term Loan Agreement (“Term Loan”) with certain financial institutions, whereby it borrowed an aggregate principal amount of$165.0 million. During 2011, the Company repaid$20.0 million of the Term Loan. The Term Loan matures in June 2013, and borrowings generally bear interest at a variable rate equal to a margin over LIBOR. The margin varies with the ratio of the Company’s total funded debt to consolidated earnings before interest, taxes, depreciation, and amortization (“EBITDA”) as defined in the Loan Agreement. These interest rates also vary as LIBOR varies. At June 30, 2012, the interest rate of 1.2% was based on a margin over LIBOR. The Term Loan remains classified as long-term debt at June 30, 2012 as the Company has the current intent and ability to use the availability under its credit facility to refinance the Term Loan.

The Company also has a $500.0 millionrevolving credit facility (the “Facility”) that matures in June 2016. The Facility permits the Company to borrow at interest rates based upon a margin above LIBOR. The margin varies with the ratio of total funded debt to EBITDA, net of specified cash, as defined in the Facility. These interest rates also vary as LIBOR varies. At June 30, 2012, there were no borrowings outstanding on the Facility. The Company pays a commitment fee on the unused amount of the Facility, which also varies with the ratio of total funded debt to EBITDA.

Based on rates for instruments with comparable maturities and terms, which are classified as Level 2 inputs, the approximate fair value of the Company's debt was $946.7 million and $951.0 million as of June 30, 2012 and December 31, 2011, respectively.

The Notes, the Term Loan, and the Facility require the Company to meet specified financial ratios and to satisfy certain financial condition tests. The Company was in compliance with all financial debt covenants as of June 30, 2012.

The Company entered into interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk. (See also Note 14 of Notes to Condensed Consolidated Financial Statements.)

At June 30, 2012, other notes payable of approximately $15.9 million were outstanding with a weighted average interest rate of1.8%.

9. PENSION PLANS

The Company’s net periodic defined benefit pension cost is comprised of the following components (in millions):

	Three Months Ended						Six Months Ended
	June 30, 2012			July 2, 2011			June 30, 2012			July 2, 2011
Service cost	$	0.6		$	0.6		$	1.2		$	1.3
Interest cost	1.8			2.0			3.7			4.0
Expected return on plan assets	(1.9		)	(1.8		)	(3.7		)	(3.6		)
Amortization of prior service cost and net actuarial loss	1.0			0.9			1.9			1.8
Net periodic benefit expense	$	1.5		$	1.7		$	3.1		$	3.5

The estimated net actuarial loss and prior service cost for defined benefit pension plans that will be amortized from Accumulated Other Comprehensive Loss into net periodic benefit cost during the 2012 fiscal year is $3.6 million and $0.2 million, respectively.

During the first six months of 2012 and 2011, the Company contributed $3.9 million and $1.2 million, respectively, to defined benefit pension plans. The Company expects to contribute an additional $3.8 million, for total contributions of $7.7 million in 2012. The Company contributed a total of $6.5 million in 2011. The assumptions used in the valuation of the Company’s pension plans and in the target investment allocation have remained the same as those disclosed in the Company’s 2011 Annual Report on Form 10-K filed on February 29, 2012.

10. SHAREHOLDERS’ EQUITY

The Company recognized approximately $2.4 million and $4.4 million in share-based compensation expense for the three month period endedJune 30, 2012 and July 2, 2011, respectively. Share-based compensation expense for the six month period endedJune 30, 2012 and July 2, 2011 was $4.5 million and $6.2 million, respectively. The total excess income tax benefit recognized relating to share-based compensation for the six months endedJune 30, 2012 and July 2, 2011 was approximately $0.9 million and $1.0 million, respectively. The Company recognizes compensation expense on grants of share-based compensation awards on a straight-line basis over the vesting period of each award. As of June 30, 2012, total unrecognized compensation cost related to share-based compensation awards was approximately $26.3 million, net of estimated forfeitures, which the Company expects to recognize over a weighted average period of approximately 3.1 years.

The Company was authorized, as of June 30, 2012, to deliver up to 5.0 million shares of common stock upon exercise of non-qualified stock options or incentive stock options, or upon grant or in payment of stock appreciation rights, restricted stock and restricted stock units. Approximately 1.0 million shares were available for future grant or payment under the various plans at June 30, 2012.

Share-based Incentive Awards

The Company uses several forms of share-based incentive awards, including non-qualified stock options, incentive stock options, and stock appreciation rights (“SARs”). All grants are made at prices equal to the fair market value of the stock on the grant dates, and expire ten years from the grant date. The Company values restricted stock awards at the closing market value of its common stock on the date of grant and restrictions generally lapse three years after the date of grant.

The majority of the Company’s annual share-based incentive awards are made in the fiscal second quarter. For the six months ended June 30, 2012 and July 2, 2011, respectively, 255,225 and 333,750 share-based incentive awards were granted. The per share weighted average fair value of share-based incentive awards granted during those respective periods was $22.45 and $26.81.

The assumptions used in our Black-Scholes valuation related to grants were as follows:

	June 30, 2012		July 2, 2011
Risk-free interest rate	1.3	%	2.6	%
Expected life (years)	7.0		7.0
Expected volatility	37.6	%	35.5	%
Expected dividend yield	1.2	%	1.0	%

A summary of share-based awards (options and SARs) as of June 30, 2012 follows below. Forfeitures of share-based awards during the six months endedJune 30, 2012 totaled 13,640.

Number of Shares	Shares	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (years)	Aggregate Intrinsic Value (in millions)
Outstanding	1,849,830	$	52.26	6.5	$	21.9
Exercisable	914,065	41.92		4.4	18.6

Restricted Stock and Restricted Stock Units

Changes in restricted stock awards for the six months ended June 30, 2012 were as follows:

	Shares		Weighted Average Value
Unvested restricted stock awards, December 31, 2011	138,330		$	60.67
Granted	92,236		63.56
Vested	(32,300	)	43.11
Forfeited	(255	)	63.56
Unvested restricted stock awards June 30, 2012	198,011		$	64.85

As of June 30, 2012, the Company's restricted stock outstanding had a weighted average grant date fair value of $64.85. The Company values restricted stock awards at the closing market value of its common stock on the date of grant and restrictions generally lapse three years after the date of the grant.

11. INCOME TAXES

The effective tax rate for the three months endedJune 30, 2012 was 30.5% versus 28.6% for the three months endedJuly 2, 2011. The effective tax rate for the six months endedJune 30, 2012 was 28.7% versus 30.0% for the six months endedJuly 2, 2011. The change in the effective rates was driven primarily by the mix of global earnings distribution of income.

As of both June 30, 2012 and December 31, 2011, the Company had approximately $7.1 million of unrecognized tax benefits, all of which would affect its effective tax rate if recognized. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. U.S. federal tax returns from 2008 through 2011 and various state tax returns remain subject to income tax examinations by tax authorities.

12. EARNINGS PER SHARE (EPS)

The numerator for the calculation of basic and diluted earnings per share is Net Income Attributable to Regal Beloit Corporation. The denominator is computed as follows (in millions):

	Three Months Ended		Six Months Ended
	June 30, 2012	July 2, 2011	June 30, 2012	July 2, 2011
Denominator for basic EPS (weighted average)	41.7	38.7	41.6	38.6
Effect of dilutive securities	0.3	0.5	0.4	0.6
Denominator for diluted EPS	42.0	39.2	42.0	39.2

The “Effect of dilutive securities” represents the dilution impact of equity awards for the three and six months endedJune 30, 2012 and July 2, 2011, respectively. As of the three months endedJune 30, 2012, the Company had approximately 0.6 million shares where the exercise price was above the market price, and which were excluded from the calculation of the effect dilutive shares as the effect of such options was anti-dilutive. There were no shares where the exercise price was above the market price for the three months endedJuly 2, 2011. For the six months endedJune 30, 2012 and July 2, 2011, there were 0.6 million and 0.4 million, respectively, where the exercise price was above the market price, and which were excluded from the calculation of the effect of dilutive shares as the effect of such options was anti-dilutive.

13.CONTINGENCIES

One of the Company’s subsidiaries that it acquired in 2007 is subject to numerous claims filed in various jurisdictions relating to certain sub-fractional motors that were primarily manufactured through 2004 and that were included as components of residential and commercial ventilation units marketed by a third party. These claims generally allege that the ventilation units were the cause of fires. Based on the current facts, the Company does not believe these claims, individually or in the aggregate, will have a material effect on its interim consolidated financial statements as a whole.

The Company is, from time to time, party to litigation that arises in the normal course of its business operations, including product warranty and liability claims, contract disputes and environmental, asbestos, employment and other litigation matters. The Company’s products are used in a variety of industrial, commercial and residential applications that subject the Company to claims that the use of its products is alleged to have resulted in injury or other damage. The Company accrues for anticipated costs in defending against such lawsuits in amounts that the Company believes are adequate, and the Company does not believe that the outcome of any such lawsuit, individually or in the aggregate, will have a material effect on the Company’s interim consolidated financial statements as a whole.

14. DERIVATIVE INSTRUMENTS

The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are commodity price risk, currency exchange, and interest rate risk. Forward contracts on certain commodities are entered into to manage the price risk associated with forecasted purchases of materials used in the Company’s manufacturing process. Forward contracts on certain currencies are entered into to manage forecasted cash flows in certain foreign currencies. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating rate borrowings.

The Company must recognize all derivative instruments as either assets or liabilities at fair value in the condensed consolidated balance sheets. The Company designates commodity forward contracts as cash flow hedges of forecasted purchases of commodities, currency forward contracts as cash flow hedges of forecasted foreign currency cash flows and interest rate swaps as cash flow hedges of forecasted LIBOR-based interest payments. There were no significant collateral deposits on derivative financial instruments as of June 30, 2012.

Cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income or loss and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or changes in market value of derivatives not designated as hedges are recognized in current earnings. All derivative instruments used by the Company impact operating cash flows.

At June 30, 2012, the Company had an additional $(2.2) million, net of tax, of derivative losses on closed hedge instruments in Accumulated Other Comprehensive Income (Loss) (“AOCI”) that will be realized in earnings when the hedged items impact earnings. At December 31, 2011, the Company had an additional $(2.5) million, net of tax, of derivative losses on closed hedge instruments in AOCI that was realized in earnings when the hedged items impacted earnings.

As of June 30, 2012, the Company had outstanding the following commodity forward contracts (with maturities extending through September 2013) to hedge forecasted purchases of commodities (notional amounts expressed in terms of the dollar value of the hedged item in millions):

	Notional Amount
Copper	$	141.0
Aluminum	8.7

As of June 30, 2012, the Company had outstanding the following currency forward contracts (with maturities extending through December 2014) to hedge forecasted foreign currency cash flows (in millions):

	Notional Amount
Mexican Peso	$	216.2
Chinese Renminbi	156.4
Indian Rupee	45.5
Thai Baht	12.3

As of June 30, 2012, the total notional amount of the Company’s receive-variable/pay-fixed interest rate swaps was $250.0 million (with maturities extending to August 2017).

Fair values of derivative instruments as of June 30, 2012 and December 31, 2011 were (in millions):

The net AOCI hedging component balance of$(32.6) million loss at June 30, 2012 includes $(14.5) million of net current deferred losses expected to be realized in the next twelve months.

15. FAIR VALUE

The Company uses a three-tier hierarchy to assess the inputs used to measure the fair value of financial assets and liabilities.

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities
Level 2	Unadjusted quoted prices in active markets for similar assets or liabilities, or
	Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or
	Inputs other than quoted prices that are observable for the asset or liability
Level 3	Unobservable inputs for the asset or liability

The Company uses the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value of the Company's accounts receivable, accounts payable and variable rate debt approximated book value as of June 30, 2012 and December 31, 2011, respectively, due to their short-term nature and the fact that applicable interest rates approximated market rates of interest.

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2012 and December 31, 2011 (in millions):

	June 30, 2012		December 31, 2011		Classification
Assets:
Prepaid Expenses and Other Current Assets:
Derivative Currency Contracts	$	3.1	$	0.5	Level 2
Derivative Commodity Contracts	2.5		2.6		Level 2
Other Noncurrent Assets:
Derivative Currency Contracts	2.8		0.1		Level 2
Derivative Commodity Contracts	0.1		1.0		Level 2
Liabilities:
Other Accrued Expenses:
Deferred Contingent Purchase Price	$	3.1	$	2.0	Level 3
Hedging Obligations Current:
Derivative Currency Contracts	8.0		13.6		Level 2
Derivative Commodity Contracts	5.5		12.5		Level 2
Hedging Obligations:
Interest Rate Swap	39.5		42.0		Level 2
Derivative Currency Contracts	3.7		11.7		Level 2
Derivative Commodity Contracts	0.3		1.4		Level 2
Other Noncurrent Liabilities:
Deferred Contingent Purchase Price	20.1		21.5		Level 3

The table below sets forth a summary of changes in fair market value of the Company’s Level 3 liabilities for the three and six months ended June 30, 2012 and July 2, 2011 (in millions):

	Three Months Ended					Six Months Ended
	June 30, 2012			July 2, 2011		June 30, 2012			July 2, 2011
Beginning Balance	$	23.8		$	9.2	$	23.5		$	11.0
Valuation Adjustments	0.3			—		0.6			(1.8		)
Acquisitions	—			16.7		—			16.7
Payments	(0.9		)	—		(0.9		)	—
Ending Balance	$	23.2		$	25.9	$	23.2		$	25.9

The Company’s derivative contracts are valued at fair value using the market or income approaches. The Company measures the fair value of foreign exchange contracts using Level 2 inputs based on observable spot and forward rates in active markets. The Company measures the fair value of commodity contracts using Level 2 inputs through observable market transactions in active markets provided by financial institutions. The Company measures the fair value of interest rate swaps using Level 2 inputs in an income approach for valuation based on expected interest rate yield curves over the remaining duration of the interest rate swaps. During the six months ended June 30, 2012, there were no transfers between classification Levels 1, 2 or 3.

The Level 3 liabilities described above are comprised entirely of the deferred contingent purchase price of two of the Company’s acquisitions and are measured using Level 3 inputs. In connection with the two acquisitions, the Company had a contingent consideration fair value of $23.2 million as of June 30, 2012 which reflects a $0.6 millionincrease in the liability from December 31, 2011. Payments of$0.9 million were made during the three months endedJune 30, 2012. The contingent consideration, payable in cash, is based upon sales or earnings before interest and income taxes for the acquired businesses for the applicable contingency period. The fair value of the contingent consideration is a Level 3 input; the measurement of which is derived using a probability weighted discounted cash flow analysis. The Company has estimated that the maximum contingent amount will be paid under both agreements so the key assumption is the estimated timing of the payments. The discounted cash flow utilized risk-based discount rates ranging from approximately 5.0% to 8.0%.

See Note 8 of Notes to Condensed Consolidated Financial Statements for the disclosure on the Company's fair value of debt at June 30, 2012 and December 31, 2011.

16. RELATED PARTY TRANSACTIONS

As part of the consideration paid for the acquisition of certain assets of Elco S.p.A. on November 1, 2010, the Company assumed $22.3 millionpayable to an entity that is affiliated with its Elco Group B.V. joint venture partner resulting from a bankruptcy proceeding involving Elco S.p.A.. The amount is payable in semi-annual payments that end in the third quarter of 2012. During the first six months of 2012, $5.3 millionwas paid by the Company. The Company has included the remaining balance in Other Accrued Expenses.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context requires otherwise, references in this Item 2 to “we,” “us,” “our” or the “Company” refer collectively to Regal Beloit Corporation and its subsidiaries.

Overview

Over the past several years, as part of our strategic growth plans, we have typically acquired multiple businesses in any given fiscal year. When we refer to the financial impact of the “recently acquired businesses,” we are referring to the results of operations of acquired businesses prior to the first anniversary of their acquisition.

On an ongoing basis, we focus on a variety of key indicators to monitor business performance. These indicators include organic and total sales growth (including volume and price components), gross profit margin, operating profit, net income and earnings per share, and measures to optimize the management of working capital, capital expenditures, cash flow and Return On Invested Capital (“ROIC”). We monitor these indicators, as well as our corporate governance practices (including our Code of Business Conduct and Ethics), to ensure that we maintain business health and strong internal controls.

To achieve our financial objectives, we are focused on initiatives to drive and fund growth. We seek to capture significant opportunities for growth by identifying and meeting customer product needs within our core product categories, developing new products, and identifying category expansion opportunities. We meet these customer product needs through focused product research and development efforts as well as through a disciplined acquisition strategy. Our acquisition strategy emphasizes acquiring companies that offer market growth potential as a result of geographic base, technology or synergy opportunities. The cash flow needed to fund our growth is developed through continuous, corporate-wide initiatives to lower costs and increase effective asset utilization.

We also prioritize investments that generate higher return on capital. Our management team is compensated based on a modified Economic Value Added (“EVA”) program which reinforces capital allocation disciplines that drive increases in shareholder value. The key metrics in our program include total sales growth, organic sales growth, operating margin percent, operating cash flow as a percent of net income, and ROIC.

Given the current global economic uncertainty, we anticipate that the near-term operating environment will remain challenging. Slower economic growth or recessions in the U.S. and international markets may reduce the demand for our products. In particular, we have seen recent period-to-period declines in sales of our products used in residential HVAC applications, in part due to continued weakness in the U.S. residential housing markets as well as the adverse impact of the R22 dry-ship conversion.

Net sales for the second quarter 2012 increased 26.7% to $863.9 million compared to $681.8 million in the second quarter 2011. Net sales for the second quarter 2012 included $225.2 million of incremental net sales from recently acquired businesses.

Net Income Attributable to Regal Beloit Corporation increased 82.8% to $62.7 million for the second quarter 2012 compared to $34.3 million for the second quarter 2011. Diluted earnings per share increased to $1.49 for the second quarter 2012 compared to $.88 for the second quarter 2011.

Net cash provided by operating activities was $204.4 million for the six months ended June 30, 2012, an increase of $94.8 million from the comparable prior year period.

Liquidity and Capital Resources

Our principal source of liquidity is operating cash flow. In addition to operating income, other significant factors affect our working capital levels, capital expenditures, dividends, acquisitions, availability of debt financing, and the ability to attract long-term capital on acceptable terms.

Cash flow provided by operating activities (“operating cash flow”) was $204.4 million for the six months ended June 30, 2012, a $94.8 million increase from the six months ended July 2, 2011. The increase in operating cash flow was driven by higher sales volume and earnings from 2011 acquisitions reflected in full six month 2012 operating results. Net income was $37.4 million higher for the six months ended June 30, 2012 compared to the six months ended July 2, 2011.

Cash flow used in investing activities was $135.0 million for the six months ended June 30, 2012, a $130.6 million increase from the six months ended July 2, 2011. Capital expenditures were $44.8 million in the six months ended June 30, 2012. Business acquisitions were $95.3 million for the six months ended June 30, 2012, driven by the acquisition of Milwaukee Gear Company, compared to $22.1 million for the six months ended July 2, 2011.

Cash flow used in financing activities for the six months ended June 30, 2012 was $20.3 million compared to $7.2 million in the six months ended July 2, 2011, primarily due to the 2012 increase in net repayment of borrowings.

Working capital was $820.5 million at June 30, 2012, an increase of 7.0% from $766.6 million at December 31, 2011.

The following table presents selected financial information and statistics as of June 30, 2012 and December 31, 2011 (in millions):

Working Capital	820.5		766.6
Current Ratio	2.3:1		2.5:1

A significant amount of operating income is earned in jurisdictions where it is deemed to be permanently reinvested. Our most prominent jurisdiction of operation is the U.S. We currently do not intend nor foresee a need to repatriate funds to the U.S., and no provision for U.S. income taxes has been made with respect to such earnings. It is expected that existing cash and cash equivalents available to the U.S., the cash generated by U.S. operations, committed credit lines as well as the expected ability to access the capital markets will be sufficient to fund U.S. operating and capital needs for at least the next twelve months and thereafter for the foreseeable future. There are no current trends, demands or uncertainties that are believed reasonably likely to require repatriation or to have a material impact on our ability to fund our U.S. operations.

At June 30, 2012, we had $750.0 million of senior notes (the “Notes”) outstanding. Details on the senior notes at June 30, 2012 were (in millions):

	Principal		Interest Rate	Maturity

Fixed Rate Series 2011A	170.0		4.9 to 5.1%	July 2023
	$	750.0
(1) Interest rates vary as LIBOR varies. At June 30, 2012, the interest rate was between 1.1% and 1.2%.

We have interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk.

In 2008, we entered into a Term Loan Agreement (“Term Loan”) with certain financial institutions, pursuant to which it borrowed an aggregate principal amount of $165.0 million. During 2011, we repaid $20.0 million of the Term Loan. The Term Loan matures in June 2013, and borrowings generally bear interest at a variable rate equal to a margin over LIBOR which varies with the ratio of our total funded debt to consolidated earnings before interest, taxes, depreciation, and amortization (“EBITDA”) as defined in the Term Loan. These interest rates also vary as LIBOR varies. At June 30, 2012, the interest rate of 1.2% was based on a margin over LIBOR. The Term Loan remains classified as long-term debt at June 30, 2012 as the Company has the current intent and ability to use the availability under its credit facility to refinance the Term Loan.

We also have a $500.0 million revolving credit facility that matures in 2016. The Facility permits borrowing at interest rates based upon a margin above LIBOR. The margin varies with the ratio of total funded debt to EBITDA as defined in the Facility. These interest rates also vary as LIBOR varies. At June 30, 2012, there were no borrowings outstanding on the Facility. We had $473.8 million of available borrowing capacity under the Facility at June 30, 2012.

The Notes, the Term Loan and the Facility require us to meet specified financial ratios and to satisfy certain financial condition tests. We were in compliance with all financial debt covenants as of June 30, 2012.

Critical Accounting Policies and Estimates

Our disclosures of critical accounting policies, which are contained in its Annual Report on Form 10-K for the year ended December 31, 2011, have not materially changed since that report was filed.

The Condensed Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles that often require management to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts presented and disclosed in the financial statements.  Management reviews these estimates and assumptions based on

historical experience, changes in business conditions and other relevant factors they believe to be reasonable under the circumstances.  In any given reporting period, our actual results may differ from the estimates and assumptions used in preparing the Condensed Consolidated Financial Statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk relating to our operations due to changes in interest rates, foreign currency exchange rates and commodity prices of purchased raw materials. We manage the exposure to these risks through a combination of normal operating and financing activities and derivative financial instruments such as interest rate swaps, commodity cash flow hedges and foreign currency forward exchange contracts. All hedging transactions are authorized and executed pursuant to clearly defined policies and procedures, which strictly prohibit the use of financial instruments for speculative purposes.

All hedges are recorded on the balance sheet at fair value and are accounted for as cash flow hedges, with changes in fair value recorded in Accumulated Other Comprehensive Income (Loss) (“AOCI”) in each accounting period. The ineffective portion of the change in fair value, if any, is recorded in earnings in the period of change.

Interest Rate Risk

We are exposed to interest rate risk on certain of our short-term and long-term debt obligations used to finance our operations and acquisitions. At June 30, 2012, net of interest rate swaps, we had $504.8 million of fixed rate debt and $406.1 million of variable rate debt. As a result, interest rate changes in variable rate debt impact future earnings and cash flow assuming other factors are constant. We utilize interest rate swaps to manage fluctuations in cash flows resulting from exposure to interest rate risk on forecasted variable rate interest payments. We have LIBOR-based floating rate borrowings, which expose us to variability in interest payments due to changes in interest rates. A hypothetical 10% change in the weighted average borrowing rate on outstanding variable rate debt at June 30, 2012 would result in a change in after-tax annualized earnings of approximately $0.1 million.

We entered into pay fixed/receive LIBOR-based floating interest rate swaps to manage fluctuations in cash flows resulting from interest rate risk. These interest rate swaps have been designated as cash flow hedges against forecasted LIBOR-based interest payments. Details regarding these instruments, as of June 30, 2012, are as follows (in millions):

Instrument	Notional Amount		Maturity	Rate Paid		Rate Received	Fair Value (Loss)
Swap	$	150.0	August 23, 2014	5.3	%	LIBOR (3 month)	$	(16.2	)
Swap	100.0		August 23, 2017	5.4	%	LIBOR (3 month)	(23.3		)

As of June 30, 2012 and December 31, 2011, the interest rate swap liability of $(39.5) million and $(42.0) million, respectively, was included in Hedging Obligations. The unrealized loss on the effective portion of the contracts net of tax of $(24.5) million and $(26.0) million as of June 30, 2012 and December 31, 2011, respectively, was recorded in AOCI.

Foreign Currency Risk

We are also exposed to foreign currency risks that arise from normal business operations. These risks include the translation of local currency balances of foreign subsidiaries, intercompany loans with foreign subsidiaries and transactions denominated in foreign currencies. Our objective is to minimize its exposure to these risks through a combination of normal operating activities and the utilization of foreign currency exchange contracts to manage our exposure on the transactions denominated in currencies other than the applicable functional currency. Contracts are executed with creditworthy banks and are denominated in currencies of major industrial countries. We do not hedge our exposure to the translation of reported results of foreign subsidiaries from local currency to United States dollars.

As of June 30, 2012, derivative currency assets (liabilities) of $3.1 million, $2.8 million, $(8.0) million, and $(3.7) million, are recorded in Prepaid Expenses, Other Noncurrent Assets, Hedging Obligations-Current, and Hedging Obligations, respectively. As of December 31, 2011, derivative currency assets (liabilities) of $0.5 million, $0.1 million, $(13.6) million, and $(11.7) million are recorded in Prepaid Expenses, Other Noncurrent Assets, Hedging Obligations-Current, and Hedging Obligations, respectively. The unrealized (loss) on the effective portion of the contracts of $(3.7) million net of tax, and $(15.4) million net of tax, as of June 30, 2012 and December 31, 2011, was recorded in AOCI. At June 30, 2012, we had an additional $(1.2) million, net of tax, of currency losses on closed hedge instruments in AOCI that will be realized in earnings when the hedged items impact earnings. At December 31, 2011, we had an additional $0.3 million of derivative currency gains on closed hedge instruments in AOCI that were realized in 2012 earnings when the hedged items impacted earnings.

The following table quantifies the outstanding foreign exchange contracts intended to hedge non-U.S. dollar denominated receivables and payables and the corresponding impact on the value of these instruments assuming a hypothetical 10% appreciation/depreciation of their counter currency on June 30, 2012 ( in millions):

15

						Gain (Loss) From
Currency	Notional Amount		Fair Value			10% Appreciation of Counter Currency		10% Depreciation of Counter Currency
Mexican Peso	$	216.2	$	(1.9	)	$	21.6	$	(21.6	)
Chinese Renminbi	156.4		(0.9		)	15.6		(15.6		)
Indian Rupee	45.5		(2.8		)	4.6		(4.6		)
Thai Baht	12.3		(0.2		)	1.2		(1.2		)

Gains and losses indicated in the sensitivity analysis would be offset by gains and losses on the underlying forecasted non-U.S. dollar denominated cash flows.

Commodity Price Risk

We periodically enter into commodity hedging transactions to reduce the impact of changing prices for certain commodities such as copper and aluminum based upon forecasted purchases of such commodities. These transactions are designated as cash flow hedges and the contract terms of commodity hedge instruments generally mirror those of the hedged item, providing a high degree of risk reduction and correlation.

Derivative commodity assets (liabilities) of $2.5 million, $0.1 million, $(5.5) million, and $(0.3) million are recorded in Prepaid Expenses, Other Noncurrent Assets, Hedging Obligations-Current, and Hedging Obligations, respectively, at June 30, 2012. Derivative commodity assets (liabilities) of $2.6 million, $1.0 million, $(12.5), and $(1.4) million are recorded in Prepaid Expenses, Other Noncurrent Assets, Hedging Obligations-Current and Hedging Obligations, respectively, at December 31, 2011. The unrealized gain (loss) on the effective portion of the contracts of $(1.8) million net of tax and $(6.4) million net of tax, as of June 30, 2012 and December 31, 2011, respectively, was recorded in AOCI. At June 30, 2012, we had an additional $(1.0) million, net of tax, of derivative commodity losses on closed hedge instruments in AOCI that will be realized in earnings when the hedged items impact earnings. At December 31, 2011, there was an additional $(3.0) million, net of tax, of derivative commodity losses on closed hedge instruments in AOCI that were realized in 2012 earnings when the hedged items impacted earnings.

The following table quantifies the outstanding commodity contracts intended to hedge raw material commodity prices and the corresponding impact on the value of these instruments assuming a hypothetical 10% appreciation/depreciation of their prices on June 30, 2012 (dollars in millions):

					Gain (Loss) From
Commodity	Notional Amount	Fair Value			10% Appreciation of Commodity Prices		10% Depreciation of Commodity Prices
Copper	141.0	$	(2.4	)	$	14.1	$	(14.1	)
Aluminum	8.7	(0.8		)	0.9		(0.9		)

Gains and losses indicated in the sensitivity analysis would be offset by the actual prices of the commodities.

The net AOCI balance of $(32.6) million loss at June 30, 2012 includes $(14.5) million of net current deferred losses expected to be realized in the next twelve months.

Contingencies

CONTINGENCIES

One of the Company’s subsidiaries that it acquired in 2007 is subject to numerous claims filed in various jurisdictions relating to certain sub-fractional motors that were primarily manufactured through 2004 and that were included as components of residential and commercial ventilation units marketed by a third party. These claims generally allege that the ventilation units were the cause of fires. Based on the current facts, the Company does not believe these claims, individually or in the aggregate, will have a material effect on its interim consolidated financial statements as a whole.

The Company is, from time to time, party to litigation that arises in the normal course of its business operations, including product warranty and liability claims, contract disputes and environmental, asbestos, employment and other litigation matters. The Company’s products are used in a variety of industrial, commercial and residential applications that subject the Company to claims that the use of its products is alleged to have resulted in injury or other damage. The Company accrues for anticipated costs in defending against such lawsuits in amounts that the Company believes are adequate, and the Company does not believe that the outcome of any such lawsuit, individually or in the aggregate, will have a material effect on the Company’s interim consolidated financial statements as a whole.

Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

The Company uses a three-tier hierarchy to assess the inputs used to measure the fair value of financial assets and liabilities.

Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities
Level 2	Unadjusted quoted prices in active markets for similar assets or liabilities, or
	Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or
	Inputs other than quoted prices that are observable for the asset or liability
Level 3	Unobservable inputs for the asset or liability

The Company uses the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value of the Company's accounts receivable, accounts payable and variable rate debt approximated book value as of June 30, 2012 and December 31, 2011, respectively, due to their short-term nature and the fact that applicable interest rates approximated market rates of interest.

The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2012 and December 31, 2011 (in millions):

	June 30, 2012		December 31, 2011		Classification
Assets:
Prepaid Expenses and Other Current Assets:
Derivative Currency Contracts	$	3.1	$	0.5	Level 2
Derivative Commodity Contracts	2.5		2.6		Level 2
Other Noncurrent Assets:
Derivative Currency Contracts	2.8		0.1		Level 2
Derivative Commodity Contracts	0.1		1.0		Level 2
Liabilities:
Other Accrued Expenses:
Deferred Contingent Purchase Price	$	3.1	$	2.0	Level 3
Hedging Obligations Current:
Derivative Currency Contracts	8.0		13.6		Level 2
Derivative Commodity Contracts	5.5		12.5		Level 2
Hedging Obligations:
Interest Rate Swap	39.5		42.0		Level 2
Derivative Currency Contracts	3.7		11.7		Level 2
Derivative Commodity Contracts	0.3		1.4		Level 2
Other Noncurrent Liabilities:
Deferred Contingent Purchase Price	20.1		21.5		Level 3

The table below sets forth a summary of changes in fair market value of the Company’s Level 3 liabilities for the three and six months ended June 30, 2012 and July 2, 2011 (in millions):

	Three Months Ended					Six Months Ended
	June 30, 2012			July 2, 2011		June 30, 2012			July 2, 2011
Beginning Balance	$	23.8		$	9.2	$	23.5		$	11.0
Valuation Adjustments	0.3			—		0.6			(1.8		)
Acquisitions	—			16.7		—			16.7
Payments	(0.9		)	—		(0.9		)	—
Ending Balance	$	23.2		$	25.9	$	23.2		$	25.9

The Company’s derivative contracts are valued at fair value using the market or income approaches. The Company measures the fair value of foreign exchange contracts using Level 2 inputs based on observable spot and forward rates in active markets. The Company measures the fair value of commodity contracts using Level 2 inputs through observable market transactions in active markets provided by financial institutions. The Company measures the fair value of interest rate swaps using Level 2 inputs in an income approach for valuation based on expected interest rate yield curves over the remaining duration of the interest rate swaps. During the six months ended June 30, 2012, there were no transfers between classification Levels 1, 2 or 3.

The Level 3 liabilities described above are comprised entirely of the deferred contingent purchase price of two of the Company’s acquisitions and are measured using Level 3 inputs. In connection with the two acquisitions, the Company had a contingent consideration fair value of $23.2 million as of June 30, 2012 which reflects a $0.6 millionincrease in the liability from December 31, 2011. Payments of$0.9 million were made during the three months endedJune 30, 2012. The contingent consideration, payable in cash, is based upon sales or earnings before interest and income taxes for the acquired businesses for the applicable contingency period. The fair value of the contingent consideration is a Level 3 input; the measurement of which is derived using a probability weighted discounted cash flow analysis. The Company has estimated that the maximum contingent amount will be paid under both agreements so the key assumption is the estimated timing of the payments. The discounted cash flow utilized risk-based discount rates ranging from approximately 5.0% to 8.0%.

See Note 8 of Notes to Condensed Consolidated Financial Statements for the disclosure on the Company's fair value of debt at June 30, 2012 and December 31, 2011.

DEBT AND BANK CREDIT FACILITIES

The Company’s indebtedness as of June 30, 2012 and December 31, 2011 was as follows (in millions):

	June 30, 2012			December 31, 2011
Senior notes	$	750.0		$	750.0

At June 30, 2012, the Company had $750.0 millionof senior notes (the “Notes”) outstanding. Details on the senior notes are (in millions):

	Principal		Interest Rate	Maturity
Floating Rate Series 2007A	$	150.0	Floating (1)	August 2014
Floating Rate Series 2007A	100.0		Floating (1)	August 2017

Fixed Rate Series 2011A	230.0		4.8 to 5.0%	July 2021
Fixed Rate Series 2011A	170.0		4.9 to 5.1%	July 2023
	$	750.0

(1) Interest rates vary as LIBOR varies. At June 30, 2012, the interest rate was between1.1% and 1.2%.

In 2008, the Company entered into a Term Loan Agreement (“Term Loan”) with certain financial institutions, whereby it borrowed an aggregate principal amount of$165.0 million. During 2011, the Company repaid$20.0 million of the Term Loan. The Term Loan matures in June 2013, and borrowings generally bear interest at a variable rate equal to a margin over LIBOR. The margin varies with the ratio of the Company’s total funded debt to consolidated earnings before interest, taxes, depreciation, and amortization (“EBITDA”) as defined in the Loan Agreement. These interest rates also vary as LIBOR varies. At June 30, 2012, the interest rate of 1.2% was based on a margin over LIBOR. The Term Loan remains classified as long-term debt at June 30, 2012 as the Company has the current intent and ability to use the availability under its credit facility to refinance the Term Loan.

The Company also has a $500.0 millionrevolving credit facility (the “Facility”) that matures in June 2016. The Facility permits the Company to borrow at interest rates based upon a margin above LIBOR. The margin varies with the ratio of total funded debt to EBITDA, net of specified cash, as defined in the Facility. These interest rates also vary as LIBOR varies. At June 30, 2012, there were no borrowings outstanding on the Facility. The Company pays a commitment fee on the unused amount of the Facility, which also varies with the ratio of total funded debt to EBITDA.

Based on rates for instruments with comparable maturities and terms, which are classified as Level 2 inputs, the approximate fair value of the Company's debt was $946.7 million and $951.0 million as of June 30, 2012 and December 31, 2011, respectively.

The Notes, the Term Loan, and the Facility require the Company to meet specified financial ratios and to satisfy certain financial condition tests. The Company was in compliance with all financial debt covenants as of June 30, 2012.

The Company entered into interest rate swap agreements to manage fluctuations in cash flows resulting from interest rate risk. (See also Note 14 of Notes to Condensed Consolidated Financial Statements.)

At June 30, 2012, other notes payable of approximately $15.9 million were outstanding with a weighted average interest rate of1.8%.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

DERIVATIVE INSTRUMENTS

The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are commodity price risk, currency exchange, and interest rate risk. Forward contracts on certain commodities are entered into to manage the price risk associated with forecasted purchases of materials used in the Company’s manufacturing process. Forward contracts on certain currencies are entered into to manage forecasted cash flows in certain foreign currencies. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating rate borrowings.

The Company must recognize all derivative instruments as either assets or liabilities at fair value in the condensed consolidated balance sheets. The Company designates commodity forward contracts as cash flow hedges of forecasted purchases of commodities, currency forward contracts as cash flow hedges of forecasted foreign currency cash flows and interest rate swaps as cash flow hedges of forecasted LIBOR-based interest payments. There were no significant collateral deposits on derivative financial instruments as of June 30, 2012.

Cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income or loss and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or changes in market value of derivatives not designated as hedges are recognized in current earnings. All derivative instruments used by the Company impact operating cash flows.

At June 30, 2012, the Company had an additional $(2.2) million, net of tax, of derivative losses on closed hedge instruments in Accumulated Other Comprehensive Income (Loss) (“AOCI”) that will be realized in earnings when the hedged items impact earnings. At December 31, 2011, the Company had an additional $(2.5) million, net of tax, of derivative losses on closed hedge instruments in AOCI that was realized in earnings when the hedged items impacted earnings.

As of June 30, 2012, the Company had outstanding the following commodity forward contracts (with maturities extending through September 2013) to hedge forecasted purchases of commodities (notional amounts expressed in terms of the dollar value of the hedged item in millions):

	Notional Amount
Copper	$	141.0
Aluminum	8.7

As of June 30, 2012, the Company had outstanding the following currency forward contracts (with maturities extending through December 2014) to hedge forecasted foreign currency cash flows (in millions):

	Notional Amount
Mexican Peso	$	216.2
Chinese Renminbi	156.4
Indian Rupee	45.5
Thai Baht	12.3

As of June 30, 2012, the total notional amount of the Company’s receive-variable/pay-fixed interest rate swaps was $250.0 million (with maturities extending to August 2017).

The total excess income tax benefit recognized relating to share-based compensation for the six months endedJune 30, 2012 and July 2, 2011 was approximately $0.9 million and $1.0 million, respectively. The Company recognizes compensation expense on grants of share-based compensation awards on a straight-line basis over the vesting period of each award. As of June 30, 2012, total unrecognized compensation cost related to share-based compensation awards was approximately $26.3 million, net of estimated forfeitures, which the Company expects to recognize over a weighted average period of approximately 3.1 years.

The Company was authorized, as of June 30, 2012, to deliver up to 5.0 million shares of common stock upon exercise of non-qualified stock options or incentive stock options, or upon grant or in payment of stock appreciation rights, restricted stock and restricted stock units.

Basis Of Presentation

BASIS OF PRESENTATION

The accompanying (a) condensed consolidated balance sheet of Regal Beloit Corporation (the “Company”) as of December 31, 2011, which has been derived from audited financial statements, and (b) unaudited interim condensed consolidated financial statements as of June 30, 2012 and for the three and six months endedJune 30, 2012 and July 2, 2011, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading.

It is suggested that these condensed consolidated financial statements be read in conjunction with the financial statements and the notes thereto included in the Company’s 2011 Annual Report on Form 10-K filed on February 29, 2012.

In the opinion of management, all adjustments considered necessary for a fair presentation of financial results have been made. Except as otherwise discussed, such adjustments consist of only those of a normal recurring nature. Operating results for the three and six months endedJune 30, 2012 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 29, 2012.

The Company operates on a 52/53 week fiscal year ending on the Saturday closest to December 31.

On January 1, 2012, the Company adopted new guidance which changes the presentation of comprehensive income. Under the new guidance, the Company has reported a separate Condensed Consolidated Statement of Comprehensive Income for all periods presented.

On January 1, 2012, the Company adopted new guidance which provides an option to first assess qualitative factors in determining whether is is more likely than not that the fair value of a reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Company will perform its annual goodwill impairment test in the fourth quarter and does not expect the adoption of the guidance to have a material impact on its consolidated financial statements.

Income Taxes

INCOME TAXES

The effective tax rate for the three months endedJune 30, 2012 was 30.5% versus 28.6% for the three months endedJuly 2, 2011. The effective tax rate for the six months endedJune 30, 2012 was 28.7% versus 30.0% for the six months endedJuly 2, 2011. The change in the effective rates was driven primarily by the mix of global earnings distribution of income.

As of both June 30, 2012 and December 31, 2011, the Company had approximately $7.1 million of unrecognized tax benefits, all of which would affect its effective tax rate if recognized. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. U.S. federal tax returns from 2008 through 2011 and various state tax returns remain subject to income tax examinations by tax authorities.
