Industrie AG ("Heinrich") for Euro 39.5 million (approximately $47.1 million) in
cash and acquisition costs of approximately $1.8 million. Subsequent to May 6,

approximately $8.7 million, bringing the total ownership to 97.2% as of January
1, 2005. During 2005 the Company acquired the remaining outstanding shares for
approximately $3.7 million, bringing the total ownership to 100% as of December
31, 2005.

Purchase accounting liabilities in connection with the Heinrich acquisition were
estimated to be $11.5 million and are primarily for redundancy costs to be paid
through 2006 related to manufacturing operations and selling, general and
administrative functions. The Company began formulating its plan to incur these
costs as of the acquisition date. Additions to the Heinrich purchase accounting
liability during 2005 relate to redundancy costs recognized after 100% ownership
was achieved. As of September 30, 2006, $10.5 million has been paid related to
these liabilities.

A summary of the purchase accounting liability activity is as follows:

11. COMPREHENSIVE INCOME

Total comprehensive income for the three months ended September 30, 2006, and
October 1, 2005, was approximately $10.9 million and $9.8 million, respectively,
and for the nine months ended September 30, 2006, and October 1, 2005, was
approximately $25.0 million and $13.8 million, respectively. The adjustment for
comprehensive income consists of deferred gains and losses from foreign currency
translation adjustments and losses on available-for-sale securities for the
three and nine months ended September 30, 2006 and deferred gains and losses
from foreign currency translation adjustments and qualified cash flow hedges and
unrealized gains and losses on available-for-sale securities for the three and
nine months ended October 1, 2005. Foreign currency translation adjustment
accounts for $6.5 million and $1.0 million of the difference between other
comprehensive income and net income for the nine months ended September 30, 2006
and October 1, 2005, respectively.

12. INCOME TAXES

Income taxes for the three and nine months ended September 30, 2006 was $2.6
million and $5.2 million, respectively. Income taxes for the three months ended
September 30, 2006 includes a $1.2 million favorable tax reserve adjustment.
Income taxes for the nine months ended September 30, 2006 includes a $1.2
million favorable tax reserve adjustment, a $2.8 million benefit related to the
recognition of certain previous years net operating losses from the Teccor
acquisition partially offset by $0.9 million of charges.

13. STOCK-BASED COMPENSATION

In December 2004, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 123(R), "Share-Based Payment" ("SFAS
123(R)"). SFAS 123(R) requires public companies to recognize compensation
expense for the cost of awards of equity compensation using a fair value method.
The Company adopted SFAS 123(R) on January 1, 2006 (i.e., the first quarter of
2006) using the modified prospective method. The Company recognized the
compensation cost of all share-based awards as an expense on a straight-line
basis over the vesting period of the award. Under SFAS 123(R), benefits of tax
deductions in excess of recognized compensation expense are now reported as a
financing cash flow, rather than an operating cash flow as prescribed under the
prior accounting rules. Prior to October 1, 2005, the Company applied Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
("APB 25") to account for its stock-based compensation plans. Under APB 25, no
compensation expense was recognized for non-qualified stock option awards as
long as the exercise price of the awards on the date of grant was equal to the
current market price of the Company's stock. However, the Company did recognize
compensation expense in connection with the issuance of restricted stock. The
adoption of SFAS 123(R) primarily resulted in compensation expense being
recorded for stock options.

The following table shows total stock-based compensation expense included in the
Condensed Consolidated Statements of Income:

During the nine-month period ended September 30, 2006, options on 373,750 shares
with a strike price equal to the market price on the date of the grant were
awarded to employees and directors. These options expire seven years after the
grant date, and vest ratably over four and five years for employees and
directors, respectively. The Company used the Black-Scholes option valuation
model to determine the fair value of awards granted during the nine-month period
ended September 30, 2006. The weighted average fair value of and related
assumptions for options granted were as follows:

Forfeitures are estimated at a rate that would yield 10% over the life of the
awards.

The Company has stock option plans authorizing the granting of both incentive
and nonqualified options and other stock rights of common stock to employees and
directors. The stock options issued prior to 2002 vest over a five-year period
and are exercisable over a 10-year period commencing from the date of vesting.
The Company changed its policy in 2002 whereby the stock options vest over a
five-year period and are exercisable over a 10-year period commencing from the
date of the grant. This change was not made to stock options already granted.
The Company also has a performance share agreement in which a target amount of
performance share awards are granted based on the Company attaining certain
financial performance goals relating to return on net tangible assets and
earnings before interest, taxes, depreciation and amortization. These shares
vest over a three-year period commencing from the date of issuance. A
reconciliation of outstanding stock options and performance shares for the
period ending September 30, 2006, are shown below:

At September 30, 2006, the unrecognized compensation cost for options and
performance shares was $14.4 million before tax, and will be recognized over a
weighted average period of 3.3 years.

14. RECENT ACCOUNTING PRONOUNCEMENTS

In July 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation No. 48 ("FIN48"), Accounting for Uncertainty in Income Taxes,
which is an interpretation of SFAS No. 109, Accounting for Income Taxes. FIN 48
clarifies the accounting for income taxes by prescribing the minimum recognition
threshold a tax position is required to meet before being recognized in the
financial statements. FIN 48 provides guidance on derecognition, measurement,
classification, interest and penalties, accounting in interim periods,
disclosure and transition. FIN 48 is effective for fiscal years beginning after
December 15, 2006. We will implement this interpretation in the fiscal year
starting January 1, 2007. We cannot reasonably estimate the impact of this
interpretation at this time.

In September 2006, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 158, Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans-an amendment of FASB
Statements No. 87, 88, 106 and 132. SFAS 158 will require recognizing in the
condensed consolidated balance sheets the overfunded and underfunded status of
defined benefit postretirement plans. The overfunded or underfunded status is
defined as the difference between the fair value of plan assets and the benefit
obligation. SFAS 158 also requires the recognition the actuarial gains and
losses and the prior service costs and credits that arise during the period as a
component of other comprehensive income. We are required to adopt the statement
for our fiscal year ended December 30, 2006. We are currently evaluating the
effect that this Statement will have on our consolidated financial statements.

Results of Operations

Third Quarter, 2006

Sales increased $21.1 million or 17% to $143.4 million in the third quarter of
2006, compared to $122.3 million in the third quarter of 2005 due to improved
sales across all geographic segments. The Concord Semiconductor acquisition
added $4.0 million of sales to the Asia-Pacific segment for the third quarter of
2006.

On a geographic basis, sales in the Americas increased $4.1 million or 8% in the
third quarter of 2006, compared to the third quarter of last year. The
electronics business was the largest contributor to the sales increase
reflecting strong demand from North American distributors driven by improvement
in the markets for telecommunications and consumer electronics. The electrical
business also contributed to growth in the Americas due to continued improvement
in industrial manufacturing and realization of price increases. Automotive sales
in the Americas declined primarily due to a weaker domestic automotive market
and continued price erosion. Europe sales increased $4.3 million or 18% in the
third quarter of 2006 compared to the third quarter of 2005. The increase in
European sales was primarily due to increased sales to electronics distributors
and to a lesser extent improvement in automotive sales. Asia-Pacific sales
increased $12.7 million or 27% compared to the prior year third quarter. The
increase in Asia-Pacific sales was mainly due to strong demand for digital
consumer and telecommunications products throughout the region. Increases in
automotive sales also contributed to the Asia-Pacific growth reflecting share
gain in the growing Asian markets outside of Japan. Exchange rates had a
favorable $1.4 million effect on sales in the third quarter of 2006 compared to
the prior year quarter primarily due to changes in the Euro.

Gross profit was $47.1 million or 32.8% of sales for the third quarter of 2006,
compared to $34.3 million or 28.1% of sales in the same quarter last year. The
third quarter 2006 gross margin increased compared to the prior year quarter due
to higher sales across all geographies and the related favorable operating
leverage, partially offset by higher commodity prices for zinc and copper. The
third quarter of 2006 also includes $2.1 million of charges


                                       14



related to asset write-downs and employee-related cost pursuant to contract
obligations while the third quarter of 2005 includes $4.8 million for Ireland
severance.

Total operating expense was $34.7 million or 24.2% of sales for the third
quarter of 2006 compared to $30.2 million or 24.7% of sales for the same quarter
in the prior year. The increase in operating expense reflects additional
research and development spending to support the Company's solution selling
strategy, stock-based compensation expense of $1.2 million, higher bonus
expense, $0.8 million for asset write-downs and $1.0 million of employee-related
cost pursuant to contract obligations.

Operating income was $12.4 million or 8.6% of sales for the third quarter of
2006 compared to $4.1 million or 3.4% of sales for the same quarter of last
year. The increase in operating income compared to the prior year was due to
higher sales and operating leverage and lower severance related expenses
partially offset higher commodity prices for zinc and copper.

Interest expense was $0.5 million in the third quarter of 2006 compared to $0.6
million in the third quarter of the prior year reflecting a lower average debt
balance in 2006 compared to the prior year quarter. Other income was $0.1
million for the third quarter of 2006 compared to other income of $3.0 million
in the third quarter of last year. Other income in 2005 includes favorable
changes in exchange rates and a gain of $1.4 million related to the sale of a
40% interest in a wafer fabrication facility in Swindon, England.

Earnings from continuing operations before minority interest and income taxes
was $12.0 million for the third quarter 2006 compared to $6.5 million for the
third quarter of 2005. Income taxes were $2.6 million or a 22% effective rate,
for the third quarter of 2006 compared to $3.4 million, in the third quarter of
last year. Income taxes in the current year quarter include a $1.2 million
benefit related to a favorable tax reserve adjustment.

Net income for the third quarter of 2006 was $9.4 million or $0.42 per diluted
share compared to $3.8 million or $0.17 per diluted share for the same quarter
of last year due to the factors discussed above.

Nine Months, 2006

Sales for the first nine months of 2006 increased 16% to $407.0 million from
$351.7 million for the first nine months of last year. On a geographic basis,
sales in the Americas increased $17.0 million or 11% in the first nine months of
2006 compared to the prior year due primarily to increased North American
electronics distributor sales partially offset by lower automotive sales. Europe
sales increased $9.7 million or 13% in the first nine months of 2006 compared to
the prior year largely due to increased electronics demand and to a lesser
extent increased automotive sales. Asia-Pacific sales increased $28.6 million or
23% for the first nine months of 2006 compared to the same period in the prior
year primarily due to increased electronics sales throughout the region driven
largely by improvements in the markets for digital consumer and
telecommunications products. Automotive sales also increased over the prior year
quarter reflecting share gain in the growing Asian markets outside of Japan.
Changes in exchange rates had the effect of decreasing sales by $1.6 million for
the first nine months of 2006 compared to the prior year.

Gross profit was $123.2 million or 30.3% of sales for the first nine months of
2006 compared to $106.6 million or 30.3% of sales for the first nine months of
last year. The 2006 gross margin percentage was flat compared to the prior year
as higher sales volume and related operating leverage was offset by Ireland
severance charges of $17.1 million, higher zinc and copper commodity prices,
$2.2 million of employee-related cost pursuant to contract obligations, and $0.8
million of charges related to asset write-downs, while 2005 includes $7.5
million for Ireland severance.

Total operating expense was $99.7 million or 24.5% of sales for the first nine
months of 2006 compared to $88.8 million or 25.2% of sales last year. The
increase in operating expense reflects additional research and development
spending of $1.3 million to support the Company's solution selling strategy,
stock-based compensation expense of $3.9 million, higher bonus expense, $3.5
million related to asset write-downs and $1.0 million of accrued employee
related costs pursuant to contract obligations.


                                       15



Operating income for the first nine months of 2006 was $23.5 million or 5.8% of
sales compared to $17.9 million or 5.1% of sales for the prior year. The
improvement in operating income compared to the prior year was due to higher
sales and improved operating leverage partially offset by Ireland restructuring
charges, asset write-downs, accrued employee related costs pursuant to contract
obligations, higher commodity prices and the inclusion of stock-based
compensation expense in 2006

Interest expense was $1.3 million for the first nine months of 2006 compared to
$1.6 million last year due to lower average debt levels. Other income was $1.6
million for the first nine months of 2006 compared to $3.2 million for the same
period last year with the decrease due to a 2005 gain of $1.4 million related to
the sale of a 40% interest in a wafer fabrication facility in Swindon, England.

Earnings from continuing operations before minority interest and income taxes
was $23.8 million for the first nine months of 2006 compared to $19.4 million
the first nine months of last year. Income taxes were $5.2 million for the first
nine months of 2006 compared to $7.8 million for the first nine months of last
year. Income taxes for the first nine months of 2006 include a $2.8 million
benefit related to the recognition of certain previous years net operating
losses from the Teccor acquisition and a $1.2 million favorable tax reserve
adjustment partially offset by $0.9 million of charges.

Net income for the first nine months of 2006 was $19.2 million compared to $12.5
million for the same period last year. Earnings per share for the first nine
months of 2006 was $0.85 per diluted share compared to $0.55 per diluted share
last year.

Liquidity and Capital Resources

Assuming no material adverse changes in market conditions or interest rates,
management expects that the Company will have sufficient cash from operations to
support both its operations and its current debt obligations for the foreseeable
future.

The EFEN business, which is presented as a discontinued operation, did not
contribute significantly to cash from operations for the first, second and third
quarters of 2006 or 2005.

Littelfuse started the 2006 year with $21.9 million of cash and cash
equivalents. Net cash provided by operations was $54.4 million for the first
nine months. Net cash provided by operations includes net income of $19.2
million, stock based compensation of $3.9 million, depreciation of $23.2 million
and amortization of $2.0 million in addition to various working capital and
other items. Accounts receivable increased $13.9 million due primarily to the
increase in sales during the current year. Inventory, excluding inventory
increases as a result of 2006 acquisitions, decreased $0.4 million. Accounts
payable, accrued expenses, prepaid expenses and other items contributed $19.6
million to cash flow, primarily due to the recognition of restructuring
liabilities, partially offset by the payment of management bonuses and
restructuring charges that were previously accrued. Net cash used in investing
activities included $14.1 million in net purchases of property, plant and
equipment, $24.0 million for the purchase of Concord, $4.5 million for the
purchase of Catalina, $6.0 million for the purchase of SRC and $3.2 million of
other acquisition activity primarily for the purchase of SurgX, partially offset
by $11.6 million received from the sale of EFEN. In addition, net cash provided
by financing activities included stock option exercises of $6.0 million and
excess tax benefits on shared-based compensation of $0.4 million partially
offset by net payments of debt of $0.7 million and the purchase of $0.6 million
of treasury stock. The effects of exchange rate changes increased cash by $1.7
million. The net cash provided by operations and financing activities less
investing activities plus the effects of exchange rate changes resulted in a
$20.9 million net increase in cash. This left the Company with a cash balance of
$42.9 million at September 30, 2006.

The ratio of current assets to current liabilities was 1.7 to 1 at the end of
the third quarter of 2006 compared to 1.9 to 1 at the end of the third quarter
of 2005. The days sales in receivables was approximately 63 days at the end of
the third quarter of 2006, compared to 63 days at the end of fiscal 2005 and 60
days at the end of the third quarter of 2005. The increase in days sales in
receivables from the third quarter of the prior year was due primarily to a
higher percentage of Asian sales, which typically have longer payment cycles.
The days inventory outstanding was approximately 63 days at the end of the third
quarter of 2006 compared to 75 days at the end of


                                       16


 2005 and 73 days at end of the third quarter of 2005. The improvement in days
inventory outstanding was due to lean manufacturing and logistics initiatives
and improved production planning.

The Company's capital expenditures, net of cash from asset sales, were $4.7
million for the third quarter of 2006 compared to $5.0 million for the third
quarter of 2005. Most of the spending in 2006 relates to manufacturing process
improvements, new product introductions and capacity expansion.

Total debt at the end of the third quarter 2006 totaled $27.8 million and
consisted of the following: (1) credit revolver borrowings totaling $21.5
million, (2) foreign revolver borrowings totaling $6.3 million.

The Company has an unsecured domestic financing arrangement consisting of a
credit agreement with banks that provides a $75.0 million revolving credit
facility that expires on July 21, 2011. The revolving credit facility is subject
to a maximum indebtedness calculation and other financial covenants. At
September 30, 2006, the Company had available $53.5 million of borrowing
capability under the revolving credit facility at an interest rate of LIBOR plus
0.50% (6.01% as of September 30, 2006). The Company also had $6.0 million in
letters of credit outstanding at September 30, 2006.

The Company also has an unsecured bank line of credit that provides a Yen 0.9
billion (equivalent to $7.6 million) revolving credit facility at an interest
rate of TIBOR plus 0.875% (1.24% as of September 30, 2006). The revolving line
of credit becomes due on July 21, 2011. At September 30, 2006, the Company had
an equivalent $3.8 million outstanding on the Yen facility. The Company intends
to renew this line of credit upon maturity.

The Company also has an unsecured bank line of credit that provides a Taiwanese
Dollar 35.0 million (equivalent to $1.1 million) revolving credit facility at an
interest rate of two-years Time Deposit plus 0.145% (2.3% as of September 30,
2006). The revolving line of credit becomes due on August 18, 2009. At September
30, 2006, the Company had an equivalent $1.0 million outstanding on the
Taiwanese Dollar facility. The Company intends to renew this line of credit upon
maturity.

The Company also has various other foreign fixed rate loans totaling $1.5
million with maturity dates through August 2013.

Outlook

Fourth quarter sales are forecasted to be down at least 10% sequentially, and
maybe as much as 15%, reflecting an electronics inventory correction on top of
the normal fourth quarter seasonal decline. At these sales levels, earnings per
share would be expected to be in the $0.18 to $0.25 range, reflecting negative
operating leverage, continued costs related to acquisition integrations and
manufacturing transitions and a temporary increase in the tax rate to 36-38%.
Price increases have been implemented that will partially offset the higher
commodity prices, but because of existing contracts, some of the largest
increases will not take effect until early next year.

Company's Securities and Exchange Commission filings. Should one or more of
these risks or uncertainties materialize or should the underlying assumptions
prove incorrect, actual results and outcomes may differ materially from those
indicated or implied in the forward-looking statements. This report should be
read in conjunction with information provided in


                                       17



the financial statements appearing in the Company's Annual Report on Form 10-K
for the year ended December 31, 2005.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

The Company is exposed to market risk from changes in foreign exchange rates,
commodities and, to a lesser extent, interest rates. Management believes that
the Company's exposure to foreign exchange rates and interest rates is
immaterial and not significant enough to warrant disclosure of quantitative
information regarding market risk.

The Company had $27.8 million of debt outstanding at September 30, 2006 in the
form of lines of credit with variable rates of interest. Approximately $1.5
million of the Company's debt is at fixed rates.

A portion of the Company's operations consists of manufacturing and sales
activities in foreign countries. The Company has foreign manufacturing
facilities in Mexico, England, Ireland, China, Germany and the Philippines.
Substantially all sales in Europe are denominated in Euro, U.S. Dollar and
British Pound Sterling, and substantially all sales in the Asia-Pacific region
are denominated in U.S. Dollar, Japanese Yen and South Korean Won.

The Company's identifiable foreign exchange exposures result from the purchase
and sale of products from affiliates, repayment of intercompany trade and loan
amounts and translation of local currency amounts in consolidation of financial
results. Changes in foreign currency exchange rates or weak economic conditions
in the foreign countries in which it manufactures and distributes products could
affect the Company's sales, accounts receivable values and financial results.
The Company uses netting and offsetting intercompany account management
techniques to reduce known foreign currency exposures deemed to be material.

A risk management policy has been implemented by the Company that establishes
the procedures and controls over derivative financial instruments. Under the
policy, the Company does not use derivative financial instruments for trading
purposes and the use of such instruments is subject to the approval of senior
officers. Typically, the use of such derivative instruments is limited to
hedging activities related to specific foreign currency cash flows. The
Company's exposure related to such transactions is, in the aggregate, not
material to the Company's financial position, results of operations and cash
flows.

The Company uses various metals in the production of its products, including
zinc, copper and silver. The Company's earnings are exposed to fluctuations in
the prices of these commodities. The Company does not currently use derivative
financial instruments to mitigate this commodity price risk. A 10% increase in
the price of zinc and copper would reduce pre-tax profit by approximately $1.0
million and $1.1 million, respectively.

Item 4. Controls and Procedures

As of September 30, 2006, the Chief Executive Officer and Chief Financial
Officer of the Company evaluated the effectiveness of the disclosure controls
and procedures of the Company and concluded that these disclosure controls and
procedures are effective to ensure that material information relating to the
Company and its consolidated subsidiaries has been made known to them by the
employees of the Company and its consolidated subsidiaries during the period
preceding the filing of this Report. There were no significant changes in the
Company's internal controls during the period covered by this Report that could
materially affect these controls or could reasonably be expected to materially
affect the Company's internal control reporting, disclosures and procedures
subsequent to the last day they were evaluated by the Company's Chief Executive
Officer and Chief Financial Officer.
