NOTES TO CONDENSED CONSOLIDATED COMPARATIVE FINANCIAL STATEMENTS

1. Basis of Presentation
 
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and the requirements of Form 10-Q and applicable rules of Regulation S-X and accordingly do not include all disclosures normally required by generally accepted accounting principles for complete financial statements.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments (consisting of normal recurring accruals) which are necessary for a fair presentation. Operating results for interim periods are not necessarily indicative of operating results for the full year. Accordingly, the financial statements and notes herein should be read in conjunction with the Form 10-K of Tellabs, Inc. ("Tellabs" or the "Company"), for the year ended December 29, 2000.

Prior year results of operations were restated to reflect the adoption of Securities and Exchange Commission ("SEC") Staff Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial Statements" during the fourth quarter of 2000. In addition, certain reclassifications have been made in the 2000 financial statements to conform with the 2001 presentation.

2. Restructuring and Other Charges

On April 18, 2001, Tellabs initiated a plan to restructure its current business operations and terminate the SALIX and NetCore next-generation switching product efforts. The decision to restructure the Company's current operations was based on the recent slowdown in spending by the major telecommunications carriers, which resulted in revised business forecasts pointing to a decrease in revenue growth. As a result, the Company formulated a plan to align its cost structure with the revised outlook for the business. The decision to exit the SALIX and NetCore next-generation switching product efforts was the result of a multi-year unprofitable business forecast, which was based on analysis of current and future market conditions and direct customer interaction. Major components of the restructuring plan included: the exiting of the SALIX and NetCore next-generation switching product efforts; a strategic assessment of worldwide manufacturing capacity to better align capacity to individual product demand; a workforce reduction associated with the manufacturing capacity alignment; an assessment of global inventory levels; an analysis of outstanding purchase commitments and a review of all leased facilities, in conjunction with the completion of the Company's new corporate headquarters.

In conjunction with this plan, the Company recorded restructuring and other charges totaling $261,639,000 in the second quarter of 2001. Below is an analysis and discussion of the restructuring and other charges by major income statement classification:

(in thousands)

Income Statement Classification	Description of Charges	Accrual	Non-Cash Activity	Cash Activity	Balance at June 29, 2001
Net Product Sales	Reversal of SALIX revenue	$6,224	$2,852	$ -	$9,076
Product Cost of Sales	Inventory write-offs	90,731	(90,731)	-	-
	Purchase commitments	78,025	-	(510)	77,515
	Current asset write-offs	2,902	(2,902)	-	-
Restructuring	Severance and related	6,891	(112)	(5,705)	1,074
	Consolidation of excess facilities	38,450	-	(814)	37,636
	Disposal of property, plant and equipment	27,718	(27,718)	-	-
	Other asset write-offs	10,698	(10,652)	-	46
		$261,639	$(129,263)	$(7,029)	$125,347

Included in net product sales was a reversal of previously recognized sales of the Company's SALIX 7750 product totaling $6,224,000. In addition, the Company also reversed deferred revenue of $2,852,000 related to SALIX product sales. The Company intends to refund the $9,076,000 that it was paid during the remainder of 2001.

Included in product cost of sales were restructuring and other charges totaling $171,658,000. Of that total, $90,731,000 related to write-offs of excess and obsolete inventory, $78,025,000 related to accruals for outstanding non-cancelable inventory purchase commitments, with the remainder related to write-offs of prepaid royalties and licenses related to the SALIX product line. Below is a breakdown of the inventory and purchase commitment charges by product line:

(amounts in thousands)

Product Line	Inventory Write-Off	Purchase Commitments
SALIX/NetCore	$31,085	$8,781
Broadband Access	34,865	49,747
Other	24,781	19,497
Total	$90,731	$78,025

The SALIX/NetCore charges related directly to the exit of that business. The broadband access charges related primarily to the recently reduced demand for the CABLESPAN 2300, which resulted in a build-up of residential service units that will be superseded by new, upgraded units. The other charges were comprised primarily of common components and piece parts that were a direct result of the lower forecasted overall product demand.

From a balance sheet perspective, the inventory write-offs were taken directly against inventory, while the purchase commitments were recorded to accrued restructuring and other charges. From a cash requirement perspective, the Company is actively working with suppliers to settle the outstanding purchase commitments by the end of 2001.

Below is a breakdown of the $83,757,000 in restructuring expenses by type:

Severance and related expenses
The restructuring program will result in the reduction of approximately 550 employees throughout the world. Workforce reductions began in April 2001, and are expected to conclude in the fourth quarter of 2001. The Company recorded a charge of $6,891,000 for severance pay and related fringe benefits. In addition to these reductions, the Company also eliminated approximately 450 temporary or contract positions and will not fill approximately 1,100 open positions.

From a balance sheet standpoint, the severance and related expenses were charged to accrued restructuring and other charges. To date, approximately $5,817,000 has been charged against this reserve, principally for the cash payment of severance pay to terminated employees. The remainder of the severance and related expenditures are expected to be paid by the end of 2001.

Consolidation of excess facilities
The Company recorded charges of $38,450,000 related to the consolidation of excess facilities. The charges relate primarily to lease cancellation and non-cancelable lease costs associated with the closure of the SALIX facility in Germantown, Maryland; the closure of the NetCore facility in Wilmington, Massachusetts and the consolidation of a variety of leased buildings in Illinois, Massachusetts and Georgia, that will no longer be needed as a direct result of the headcount reductions outlined above and the decision not to fill 1,100 open positions.

From a balance sheet standpoint, $13,117,000 will be paid during the next year and was recorded to accrued restructuring and other charges. Of that total, approximately $814,000 has been paid. The remaining $25,333,000 was recorded in a long-term liability account. It is expected that these amounts will be substantially paid by 2003.

Disposal of property, plant and equipment and write-off of other assets
Tellabs recorded charges of $38,416,000 related to the disposal of property, plant and equipment and other long-term assets. Property, plant and equipment that was disposed of totaled $27,718,000 and consisted primarily of leasehold improvements, lab and data equipment and furniture. Other assets written off totaled $10,698,000 and consisted primarily of capitalized prototypes related to the SALIX next-generation switching product effort.

Overall, the restructuring actions outlined above are expected to reduce the Company's overall cost structure by approximately 5% to 6%.

As previously announced, the Company is continuing to review ways to reduce operating expenses as part of an overall effort to align its cost structure and asset base with business expectations. Management is currently studying various alternatives including additional headcount reductions, further consolidation of facilities to achieve operating efficiencies, and other related actions. Appropriate restructuring and other charges, should they be required, would be recognized in third quarter 2001 results.

3. Business Combinations

In February 2001, the Company acquired Future Networks, Inc. ("FNI"), a leader in standards-based voice and cable modem technology, for up to approximately $135,481,000. The aggregate purchase price consisted of cash paid to the former shareholders of FNI of approximately $94,896,000, cash held in escrow of approximately $35,480,000 payable contingent upon FNI achieving certain product development milestones, the value of FNI employee stock options exchanged for Tellabs stock options of approximately $4,930,000 and other acquisition costs.

During the second quarter of 2001, FNI achieved its first product development milestone, which entitles the former shareholders to receive a total cash payment of $11,010,000 from the escrow account. As a result, Tellabs accrued for the milestone payment which will be made during the third quarter. After this payment, there will be $24,470,000 remaining in the escrow account contingent upon FNI achieving its additional product milestones.

The FNI acquisition was accounted for as a purchase, and accordingly, the results of operations of the acquired business were included in the consolidated operating results of Tellabs from the date of acquisition.

The preliminary allocation of purchase price was as follows:

(In thousands)
Fair value of assets acquired	$11,339
Cost in excess of fair value	110,044
Liabilities assumed	10,372
Purchase Price (including the first contingent milestone payment)	$111,011

The total amount allocated to cost in excess of fair value is being amortized using the straight-line method over a period of seven years. Pro forma combined operating results prepared assuming the acquisition had occurred at the beginning of the year are not being presented since they would not differ materially from reported results.

4. New Accounting Policies

The Company adopted the Financial Accounting Standard Board ("FASB") Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities," during the first quarter of 2001 (For more information see Note 7. "Derivative Financial Instruments").

In June 2001, the FASB issued SFAS No. 141, "Business Combinations," and SFAS No. 142, "Goodwill and Other Intangible Assets", effective for fiscal years beginning after December 15, 2001. SFAS No. 141 eliminates the pooling-of-interests method of accounting for business combinations that has been used in the past by the Company to account for some of its acquisitions. SFAS No. 141 also modifies the criteria to recognize intangible assets apart from goodwill. Under SFAS No. 142, goodwill and intangible assets deemed to have indefinite lives will no longer be amortized, but will instead be subject to an annual impairment test. Other intangible assets will continue to be amortized over their useful lives.

Tellabs will immediately follow the business combinations guidance set forth in SFAS No. 141 for any future acquisitions. The non-amortization provisions of SFAS No. 142 will be implemented during the first quarter of 2002. The Company expects an increase of approximately $28 million in pre-tax earnings during 2002 as a result of this accounting change. The Company will perform the required transitional impairment test of goodwill during the first quarter of 2002 and has not yet determined what the effect of these tests will be on the earnings and financial position of the Company.

5. Comprehensive Income
 
Comprehensive income (loss) for the second quarter of 2001 was $(192,760,000) and $138,787,000 for the second quarter of 2000. For the first six months of 2001, comprehensive income (loss) was $(98,792,000) compared to $193,542,000 for the first six months of 2000.

6. Earnings Per Share Reconciliation

Earnings (loss) per share, assuming dilution	$ (0.43)	$ 0.38	$ (0.13)	$ 0.59

7. Derivative Financial Instruments

Effective in the first quarter of 2001, Tellabs adopted SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities". SFAS No. 133 establishes accounting and reporting standards that require companies to record all derivative instruments on the balance sheet at their fair value. Changes in the derivatives' fair value are to be reported in earnings or other comprehensive income, as appropriate.

Tellabs conducts business on a global basis in several major currencies and is subject to the risks associated with fluctuating foreign exchange rates. In response to this, Tellabs developed a foreign currency exposure management policy with the objective of mitigating financial exposure to changing foreign exchange rates, to enable management to focus its attention on its core business. This policy contemplates use of derivative financial instruments, primarily foreign currency forward exchange contracts, to hedge up to 90% of existing nonfunctional currency receivables and payables that are expected to be settled in less than one year. It is the Company's policy to enter into forward exchange contracts only to the extent necessary to meet its overall goal of minimizing nonfunctional foreign currency exposures. Tellabs does not enter into forward exchange contracts for speculative purposes.

Nonfunctional foreign currency exposures are reviewed on a monthly basis and forward exchange contracts are entered into specifically to hedge these identified exposures. The principal currencies currently being hedged by the Company are the British pound, Danish krone, Euro and U.S. dollar.

In accordance with SFAS No. 133 all forward exchange contracts are recorded on the balance sheet at fair value. Forward exchange contracts receivable are included in other current assets, while forward exchange contracts payable are included as part of accrued liabilities in the consolidated condensed balance sheet. Changes in the fair value of these instruments are included in earnings, as part of other income and expense, in the current period. The Company's current hedging practices do not qualify for special hedge accounting treatment as prescribed in SFAS No. 133 since hedges of existing assets or liabilities that will be remeasured with changes in fair value reported currently in earnings are specifically excluded. Adoption of SFAS No. 133 had no significant impact on Tellabs' consolidated financial statements.

Derivative financial instruments involve elements of market and credit risk not recognized in the financial statements. The market risk that results from these instruments relates to changes in the foreign currency exchange rates, which is expected to be partially offset by movements in the underlying assets or liabilities being held. Credit risk relates to the risk of nonperformance by a counterparty to one of the Company's derivative transactions. Tellabs does not believe there is a significant credit risk because the counterparties are all large international financial institutions with high credit ratings. In addition, the Company also limits the amount of agreements entered into with any one financial institution in order to mitigate credit risk.

Management's Discussion and Analysis

Quarter Ended June 29, 2001 Compared to Quarter Ended June 30, 2000

Significant Events and Non-Comparable Items
Net Sales for the quarter ended June 29, 2001, were $509.4 million, down 35.1% compared to sales of $785.5 million achieved during the second quarter of 2000. During 2000, Tellabs adopted SAB No. 101, "Revenue Recognition in Financial Statements," which required the Company to modify its revenue recognition policies to be in compliance with the then newly issued guidelines and related interpretive guidance. The adoption of SAB No. 101 was accounted for as a change in accounting principle with the cumulative effect of the change to prior periods reported during the first quarter of 2000.

Tellabs reported a net loss of $174.7 million for the second quarter of 2001, compared to net income of $157.1 million for the same period last year. Net loss per diluted share outstanding was $0.43 per share for the quarter ended June 29, 2001, compared to net earnings per diluted share outstanding of $0.38 per share for the second quarter of 2000. Included in second quarter 2001 earnings were charges totaling $261.6 million related to the Company's efforts to realign its cost structure with its current expectations for lower revenue growth, coupled with the Company's termination of its SALIX and NetCore next-generation switching product effort (For more information, see Note 2. "Restructuring and Other Charges"). The chart below presents pro forma financial information for the second quarter of 2001, excluding the restructuring and other charges. For comparability purposes, all subsequent quarterly comparisons will be based on this pro forma financial information.

Results of Operations
Net product sales for the quarter ended June 29, 2001, totaled $413.9 million, a decrease of 42.2% compared to the quarter ended June 30, 2000, stemming from an industry-wide slowdown in customers' equipment purchases. The overall decrease in product sales was driven primarily by lower optical networking product sales. Sales of optical networking products for the second quarter of 2001 were $221.2 million, compared to $513.1 million for the same period last year. The primary driver behind the decrease in optical networking sales was weaker TITAN® 5500/5500S and TITAN 532L systems sales. During the second quarter of 2001, the Company recognized first revenues from sales of two of its new major products: the TITAN 6500 Multiservice Transport Switch ("MTS") and the TITAN 6100 Optical Transport Switch ("OTS"). The Company expects these new products to become a more significant contributor to overall sales in the future. Sales of the Company's broadband access products were $147.8 million compared to $156.0 million in the second quarter of 2000. The reduction in broadband access product sales was a result of lower CABLESPAN® 2300 universal telephony distribution systems sales, which negated relatively strong gains achieved by the Company's FOCUS™ international-standard optical products and increased MartisDXX® managed access and transport systems sales. Sales of the Company's voice quality enhancement products totaled $44.9 million for the second quarter of 2001, compared to $47.4 million for the same period last year. The decrease in voice quality enhancement product sales was attributed mainly to lower sales of Tellabs' echo cancellation products.

Net services and other revenues for the quarter ended June 29, 2001, totaled $101.7 million, an increase of 47.7% compared to the second quarter of 2000. Net services and other revenues consist primarily of revenues generated from the Company's professional services and solutions area. The strong revenue growth achieved by the Company's professional services and solutions area was due to the installation and testing of the Company's products that were sold during the first half of 2001 and latter part of 2000.

Sales within the United States, for the second quarter of 2001, decreased 42.6% compared to the same period last year and accounted for approximately 71.4% of total sales. Sales outside the United States grew 2.5% over the second quarter of 2000, and accounted for approximately 28.6% of total sales.

Gross margin as a percentage of sales, for the quarter ended June 29, 2001, was 43.5% compared to 53.7% for the second quarter of 2000. Gross product margin as a percentage of sales for the second quarter of 2001 was 50.7% compared to 58.3% for the same period last year. The decrease in gross product margin as a percentage of sales was attributable to a variety of factors including: decreased sales volume of the Company's TITAN 5500/5500S systems and lower absorption of fixed manufacturing costs due to decreased product sales. Gross services and other margin as a percentage of sales was 14.2% for the second quarter of 2001, compared to 6.0% for the same period last year. The improvement in gross services and other margin as a percentage of sales was attributable to the Company's continued efforts to perform its services and installations utilizing the most cost-effective means available.

Operating expenses for the quarter ended June 29, 2001 totaled $224.3 million compared to $206.4 million for the quarter ended June 30, 2000. As a percentage of sales, operating expenses for the second quarter of 2001, were 43.5% compared to 26.3% for the same period last year. Research and development expenditures for the second quarter of 2001, totaled $110.6 million, an increase of 7.1% over the comparable period last year. The growth in research and development expenditures was attributable to new product development costs for the Company's optical networking product line, along with the inclusion of development costs from FNI, which was acquired in February 2001 (For more information, see Note 3. "Business Combinations"). These increased expenditures were partially offset by cost savings recognized as a result of the Company's decision to exit the SALIX and NetCore next-generation switching product area. As a percentage of sales, research and development expenditures were 21.5% compared to 13.1% for the second quarter of 2000. The growth in research and development expenditures as a percentage of sales was attributable primarily to lower overall sales in 2001. Tellabs anticipates research and development expenditures for the remainder of 2001 to decrease due primarily to the cancellation of its SALIX and NetCore next-generation switching efforts and the Company's reprioritization of its research and development activities. Overall, Tellabs continues to invest in research and development activities, both to develop new products and to modify existing technologies to meet the needs of its customers. Marketing, general and administrative expenditures for the second quarter of 2001, totaled $107.7 million, an increase of 7.4% over the comparable quarter last year. The growth in selling, general and administrative expenditures was primarily the result of staffing and business infrastructure expenditures initiated to support the Company's original growth estimates for the business. Marketing, general and administrative spending as a percentage of sales was 20.9% compared to 12.8% for the second quarter of 2000. Based upon the changing market conditions in the telecommunications industry during the first half of 2001, Tellabs has re-evaluated its short-term growth prospects and has undertaken a company wide initiative to align expenditures with its lower short-term growth forecasts. The Company anticipates that its cost control efforts will reduce marketing, general and administrative spending over the remainder of 2001.

As previously discussed, included in second quarter 2001 earnings were charges totaling $261.6 million related to the Company's restructuring efforts (For more information, see Note 2. "Restructuring and Other Charges"). The Company is continuing to review ways to reduce operating expenses as part of an overall effort to align its cost structure and asset base with business expectations. Management is currently studying various alternatives including additional headcount reductions, further consolidation of facilities to achieve operating efficiencies, and other related actions. Appropriate restructuring and other charges, should they be required, would be recognized in third quarter 2001 results.

Other income for the quarter ended June 29, 2001, totaled $14.7 million compared to $14.6 million for the second quarter of 2000. Interest income for the second quarter of 2001 totaled $11.3 million, a decrease of 21.9% compared to the second quarter of 2000. The reduction in interest income was a function both of lower prevailing interest rates on investments and lower cash balances available for investment. The decrease in interest income was partially offset by growth in other income, which resulted mainly from gains on investment activity.

The effective tax rate for the quarter ended June 29, 2001 was 31.5% compared to 31.8% for the comparable period last year. Tellabs effective tax rate reflects the benefits of research and development tax credits and lower foreign tax rates, as compared to the United States federal statutory rate.

Six Months Ended June 29, 2001 Compared to Six Months Ended June 30, 2000

Significant Events and Non-Comparable Items
Net sales for the six months ended June 29, 2001, totaled $1,281.5 million, a decrease of 9.5% compared to $1,416.7 million for the same period last year. As previously mentioned, Tellabs adopted SAB No. 101, "Revenue Recognition in Financial Statements," during 2000. The adoption of SAB No. 101 was accounted for as a change in accounting principle with the cumulative effect of the change to prior periods reported during the first period of 2000.

Tellabs reported a net loss of $52.2 million for the first half of 2001, compared to net income of $248.5 million for the same period last year. Net loss per diluted share outstanding was $0.13 per share for the first six months of 2001, compared to net earnings per diluted share outstanding of $0.59 per share for the first half of 2000. Included in 2001 earnings were charges totaling $261.6 million related to the Company's efforts to realign its cost structure with its current expectations for lower revenue growth, coupled with the Company's termination of its SALIX and NetCore next-generation switching product effort (For more information, see Note 2. "Restructuring and Other Charges"). The chart below presents pro forma financial information for the six months ended June 29, 2001, excluding the restructuring and other charges.

Included in earnings for the first six months of 2000, were charges of $5.8 million ($0.01 per diluted share) related to the Company's merger with SALIX, a gain of $19.2 million ($0.03 per diluted share) on the sale of a certain stock held as an investment and a gain of $4.6 million ($0.01 per diluted share) related to a distribution from one of the Company's technology investments. For comparability purposes, all subsequent comparisons will be based on the pro forma financial information, excluding the above-mentioned charges and gains.

Results of Operations
Net sales for the six months ended June 29, 2001, were $1,287.7 million compared to $1,416.7 million for the first half of 2000. Net product sales for the first half of 2001 totaled $1,081.3 million, a 17.5% decrease compared to the same period last year, due to an industry-wide slowdown in customers' equipment purchases. The main driver behind the overall decrease in product sales was weaker sales of the Company's optical networking products. Sales of optical networking products were $702.8 million, for the first half of 2001, compared to $906.6 million for the same period last year. The 22.5% decrease in optical networking product sales resulted mainly from lower sales of the Company's TITAN 5500/5500S and TITAN 532L systems. During the second quarter of 2001, Tellabs recognized first revenues from sales of two of its emerging products: the TITAN 6500 MTS and TITAN 6100 OTS. Sales of Tellabs' broadband access products for the first six months of 2001, totaled $300.7 million compared to $305.3 million for the same period last year. The 1.5% decline in broadband access product sales resulted primarily from weak CABLESPAN 2300 systems sales, which offset strong sales growth from the Company's FOCUS international-standard optical products and improved sales of MartisDXX managed access and transport systems. Sales of voice quality enhancement products for the first six months of 2001, totaled $77.8 million compared to $98.7 million for the first half of 2000. The 21.2% drop in voice quality enhancement product sales was attributable to lower sales of the Company's digital echo cancellation products.

Net services and other revenue for the six months ended June 29, 2001, totaled $206.4 million compared to $106.1 million for the same period last year. The 94.5% growth in net services and other revenue was a result of revenues generated from the installation and testing of Tellabs' products sold during the first half of 2001 and latter part of 2000.

Sales within the United States for the first half of 2001, decreased 17.1% over the comparable period last year and accounted for approximately 76.1% of overall sales. Sales outside the United States increased 31.4% compared to the first six months of 2000 and accounted for approximately 23.9% of total sales.

Gross margin as a percentage of sales for the six months ended June 29, 2001, was 49.0% compared to 53.2% for the first half of 2000. Gross product margin as a percentage of sales totaled 54.1% compared to 58.5% for the first six months of 2000. The decrease in gross product margin as a percentage of sales was the result of a number of factors, including: decreased sales of the Company's TITAN 5500/5500S systems; lower absorption of fixed manufacturing expenditures due to lower total sales and the accounting for customer shipping and freight revenues as sales revenue in 2001, in accordance with Emerging Issues Task Force Issue 00-10, "Accounting for Shipping and Handling Fees and Costs". Gross services and other margin as a percentage of sales was 21.8% for the first half of 2001, compared to (12.0%) for the same period last year. The growth in gross services and other margin as a percentage of sales was the result of increased installations in 2001, coupled with cost control efforts in the Company's professional services area.

Operating expenses for the six months ended June 29, 2001, were $467.5 million compared to $389.4 million for the first half of 2000. As a percentage of sales operating expenses were 36.3% in 2001 compared to 27.5% for the first six months of 2000. Research and development expenditures for the first half of 2001, totaled $238.2 million compared to $196.3 million for the same period last year. The growth in research and development spending resulted from increased expenditures in the optical networking product area, particularly for development work on the TITAN 6700 optical switch and the inclusion of expenditures from FNI, which was acquired in February 2001. These expenditures were partially offset by cost savings that resulted from the Company's decision to exit the SALIX and NetCore next-generation switching business. As a percentage of sales, research and development expenditures for the first six months of 2001, were 18.5% compared to 13.9% in the comparable period last year. Growth in research and development spending as a percentage of sales was primarily the result of lower overall sales volume in 2001. Marketing, general and administrative expenditures were $218.8 million for the first half of 2001, compared to $187.3 million for the same period last year. The 16.8% growth in marketing, general and administrative expenditures was primarily due to staffing increases and business infrastructure decisions made during the last year to support the then-anticipated growth of the Company. During the second quarter of 2001, Tellabs undertook an initiative to align its future expenditures with the new lower short-term revenue outlook for the Company, by curtailing discretionary spending, generally eliminating salary increases for 2001 and instituting an executive level pay-cut. As a percentage of sales, marketing, general and administrative expenditures for the first six months of 2001 were 17.0% compared to 13.2% for the first half of 2000.

As previously discussed, included in second quarter 2001 earnings were charges totaling $261.6 million related to the Company's restructuring efforts (For more information, see Note 2. "Restructuring and Other Charges"). The Company is continuing to review ways to reduce operating expenses as part of an overall effort to align its cost structure and asset base with business expectations. Management is currently studying various alternatives including additional headcount reductions, further consolidation of facilities to achieve operating efficiencies, and other related actions. Appropriate restructuring and other charges, should they be required, would be recognized in third quarter 2001 results.

Total other income for the six months ended June 29, 2001, was $30.8 million compared to $28.6 million for the first half of 2000. Interest income for the first half of 2001 totaled $25.8 million compared to $26.2 million for the same period last year. The decrease in interest income was due to lower available cash and short-term investment balances and lower prevailing interest rates in 2001. Other income for the first half of 2001, was $5.3 million compared to $2.7 million for the comparable period last year. The increase in other income was attributable to gains on investment sales and distributions during 2001.

The effective tax rate for the six months ended June 29, 2001, was 31.5% compared to 32.5% for the same period last year. Tellabs effective tax rate reflects the benefits of research and development tax credits and lower foreign tax rates, as compared to the United States federal statutory rate.

Liquidity and Capital Resources

Cash and cash equivalents at June 29, 2001, totaled $418.2 million compared to $329.3 million at December 29, 2000. Net cash from operations for the six months ended June 29, 2001, was $217.6 million. Principal operating cash inflows for the first half of 2001 were collections of record fourth quarter 2000 accounts receivable and earnings for the period, excluding non-cash gains and charges, primarily the restructuring and other charges of $254.6 million, net of cash paid. Principal operating cash outflows for the first half of 2001 were inventory purchases to support new product introductions, payment of 2000 taxes and the payout of the 2000 Global Incentive Plan.

The balance of accounts receivable, less allowances at June 29, 2001, was $411.7 million compared to $802.5 million at December 29, 2000. The large decrease in accounts receivable was caused by collections of strong fourth quarter 2000 sales during the first quarter of 2001, coupled with lower overall sales in 2001. Days sales in billed receivables outstanding ("DSO") was 73.6 days at June 29, 2001, compared to 72.0 days at December 29, 2000. The increase in DSO was due primarily to the geographic shift in 2001 sales, to more non-US sales as a percentage of overall sales, as compared to 2000. Tellabs continues to focus on reducing DSO by improving the underlying billing and collection process both in the US and internationally.

The balance of net inventory at June 29, 2001, was $473.6 million compared to $428.3 million at December 29, 2000. Included in the June 29, 2001, net inventory balance are reserves totaling $90.7 million taken in connection with the Company's decision to exit the SALIX and NetCore next-generation switching business and the Company's efforts to align its resources with the reduced economic demand, particularly for the CABLESPAN 2300 system (For more information, see Note 2. "Restructuring and Other Charges"). The main drivers behind the growth in inventory, during the first six months of 2001, were a buildup in new product inventory to support product introductions and meet anticipated sales and shipments of the Company's TITAN 6500 MTS that were not yet recognized as revenue. The balance of goodwill, intangible and other assets increased $89.5 million during the first six months of 2001, mainly due to the goodwill associated with the FNI acquisition.

The balance of the Company's current liabilities was $318.7 million at June 29, 2001, compared to $412.3 million at December 29, 2000. The balance of accounts payable was $111.8 million at June 29, 2001, compared to $155.0 million at the end of 2000, due in part to the Company's cost control measures implemented during the second quarter of 2001.

The balance of accrued liabilities was $106.9 million at June 29, 2001, compared to $164.0 million at the prior year-end. The reduction in accrued liabilities during 2001 was primarily the result of the payout of bonuses and incentives from the Company's 2000 Global Incentive Plan, which were accrued in the prior year. The Company anticipates accrued liabilities remaining below 2000 year-end levels due primarily to the cost alignment efforts being undertaken.

Included in current liabilities at June 29, 2001, was an accrual for restructuring and other charges, which totaled $100.0 million. The accrual stemmed from the previously mentioned restructuring efforts being undertaken by the Company and consisted primarily of reserves for inventory purchase commitments, severance costs and leased facility exit costs. The Company anticipates paying out the majority of these reserves over the remainder of 2001.

At June 29, 2001, the Company had no payable recorded for income taxes due to the effects of the previously discussed restructuring and other charges recorded during the second quarter of 2001, as well as payments of 2000 tax liabilities during the first quarter of 2001.

During the first six months of 2001, the Company used $128.9 million in cash to fund investing activities. One of the principal cash requirements during this period was cash used to fund the purchase of property, plant and equipment, which totaled $128.3 million. The primary capital expenditure during the first six months of 2001, was the construction of the Company's new Corporate Headquarters, which required a cash outlay of $43.3 million. Occupancy of the building is slated for the third quarter of 2001. The remainder of the capital expenditures was primarily for investments in equipment, to support the production of the Company's optical networking products, and research and development equipment purchases. During the first quarter of 2001, the Company also used $89.0 million, net of cash acquired, to purchase FNI. During the second quarter of 2001, FNI achieved its first product development milestone as outlined in the original purchase agreement. As a result, Tellabs will pay an additional $11.0 million to FNI during the third quarter of 2001.

The Company's short-term marketable securities balance at June 29, 2001, totaled $616.2 million compared to $693.1 million at the end of 2000. The reduction in the portfolio balance was the result of the Company managing its liquidity position to meet its then current and anticipated cash outflow requirements, such as the FNI acquisition.

Tellabs generated $18.8 million in cash from financing activities, principally from employee stock option exercises.

Working capital at June 29, 2001 totaled $1,737.7 million compared to $1,910.1 million at December 29, 2000. The current ratio at June 29, 2001 was 6.5 to 1 compared to 5.6 to 1 at December 29, 2000. Management believes the current level of working capital will be sufficient to meet the Company's normal operating needs, both now and in the foreseeable future. Sufficient resources exist to support the Company's operations either through currently available cash, through cash generated from future operations, or through short-term or long-term financing.
