5.    SEGMENT INFORMATION
 
ADTRAN operates two reportable segments—(1) the Carrier Network Division and (2) the Enterprise Network Division. We evaluate the performance of our segments based on gross profit; therefore, selling, general and administrative costs, as well as research and development, interest income/expense, and provision for income taxes are reported on an entity wide basis only. There are no inter-segment revenues.
 
The table below presents information about the reported sales and gross profit of ADTRAN’s segments for the three and six months ended June 30, 2002 and 2001. Asset information by reportable segment is not reported, since ADTRAN does not produce such information internally.

6.    RECENTLY ISSUED ACCOUNTING STANDARDS
 
In June 2001, the Financial Accounting Standards Board issued SFAS No. 141, Business Combinations, which has an effective date of June 30, 2001 for all business combinations initiated after this date. This statement requires all business combinations within the scope of the Statement to be accounted for using the purchase method of accounting. SFAS No. 141 does not currently impact ADTRAN.
 
In June 2001, the Financial Accounting Standards Board issued SFAS No. 142, Goodwill and Other Intangible Assets, which has an effective date starting with fiscal years beginning after December 15, 2001. This statement addresses the accounting for goodwill and other intangible assets. SFAS No. 142 does not currently impact ADTRAN.
 
In August 2001, the Financial Accounting Standards Board issued SFAS No. 143, Accounting for Asset Retirement Obligations (“ARO”), which has an effective date for financial statements for fiscal years beginning after June 15, 2002. This statement addresses the diversity in practice for recognizing asset retirement obligations and requires that obligations associated with the retirement of a tangible long-lived asset be recorded as a liability when those obligations are incurred, with the amount of the liability initially measured at fair value. Upon initially recognizing a liability for an ARO, an entity must capitalize the cost by recognizing an increase in the carrying amount of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, an entity either settles the obligation for its recorded amount or incurs a gain or loss upon settlement. SFAS No. 143 does not currently impact ADTRAN.
 
In October 2001, the Financial Accounting Standards Board issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which has an effective date for financial statements for fiscal years beginning after December 15, 2001. This statement, which supersedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of, requires that long-lived assets that are to be disposed of by sale be measured at the lower of book value or fair value less cost to sell. Additionally, this statement expands the scope of discontinued operations to include all components of an entity with operations that (1) can be distinguished from the rest of the entity and (2) will be eliminated from the ongoing operations of the entity in a disposal transaction. ADTRAN adopted SFAS No. 144 effective January 1, 2002, and the impact was not material to ADTRAN’s June 30, 2002 financial statements.
 
In May 2002, the Financial Accounting Standards Board issued SFAS No. 145, Rescission of FAS Nos. 4, 44, and 64, Amendment of FAS 13, and Technical Corrections as of April 2002. This statement rescinds FASB Statement No. 4, Reporting Gains and Losses from Extinguishment of Debt, and an amendment of that statement, FASB Statement No. 64, Extinguishments of Debt Made to Satisfy Sinking-Fund Requirements. The statement also rescinds FASB Statement No. 44, Accounting for Intangible Assets of Motor Carriers, and amends FASB Statement No. 13, Accounting for Leases, to eliminate an inconsistency between the required accounting for sale-leaseback transactions and the required accounting for certain lease modifications that have economic effects that are similar to sale-leaseback transactions. This statement also amends other existing authoritative pronouncements to make various technical corrections, clarify meetings, or describe their applicability under changed conditions. SFAS No. 145 does not currently impact ADTRAN.

In July 2002, the Financial Accounting Standards Board issued SFAS No. 146, Accounting for Costs Associated with Exit or Disposal, which is effective for disposal or exit activities that are initiated after December 31, 2002. This statement addresses financial accounting and reporting for costs associated with exit or disposal activities and nullifies Emerging Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring). The statement requires that a liability for a cost associated with an exit or disposal activity shall be recognized and measured initially at its fair value in the period in which liability is incurred, except for liabilities for one-time termination benefits that are incurred over time. In the unusual circumstance in which fair value cannot be reasonably estimated, the liability shall be recognized initially in the period in which fair value can be reasonably estimated. The impact of SFAS No. 146 on ADTRAN’s financial statements is not expected to be material.
 
7.    LIABILITY FOR WARRANTY RETURNS
 
ADTRAN’s products generally include warranties of five or ten years for product defects. ADTRAN accrues for warranty returns at cost to repair or replace products. This liability is included in accrued expenses in the accompanying balance sheets. The liability for warranty returns totaled approximately $1,277,000 as of June 30, 2002 and December 31, 2001.
 
8.    FINANCIAL INSTRUMENTS
 
ADTRAN evaluates its available-for-sale and held-to-maturity investments for related events or changes in circumstances that indicate a decline in value that is other-than-temporary. An impairment charge is recognized in the period in which an other-than-temporary decline is identified in an amount equal to the excess of the carrying value over the fair value. ADTRAN recorded $1,336,242 of other-than-temporary investment impairment charges during the quarter ended June 30, 2002.
 
Item 2.     Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
Overview
 
ADTRAN designs, develops, manufactures, markets and services a broad range of high speed network access products utilized by providers of telecommunications services (serviced by ADTRAN’s Carrier Networks Division or CN) and corporate end-users (serviced by ADTRAN’s Enterprise Networks Division or EN). We currently sell our products to a large number of carriers, including all RBOCs (Regional Bell Operating Companies), and to private and public enterprises worldwide.
 
Although total sales did not increase this year compared to last year due to an overall downturn in the telecommunications market, we believe we have protected our sources of revenue by maintaining our strategy of increasing unit volume and market share through the introduction of succeeding generations of products having lower selling prices and increased functionality as compared both to the prior generation of a product and to the products of competitors. An important part of ADTRAN’s strategy is to engineer the reduction of the product cost of each succeeding product generation and then to lower the product’s price based on the cost savings achieved. As a part of this strategy, we seek in most instances to be a low-cost, high-quality provider of products in our markets. ADTRAN’s success to-date is attributable in large

12


Table of Contents
measure to our ability to design our products initially with a view to their subsequent re-design, allowing both increased functionality and reduced manufacturing costs in each succeeding product generation. This strategy enables ADTRAN to sell succeeding generations of products to existing customers while increasing our market share by selling these enhanced products to new customers.
 
Our operating results have fluctuated on a quarterly basis in the past, and operating results may vary significantly in future periods due to a number of factors. We operate with very little order backlog. A substantial majority of our sales in each quarter results from orders booked in that quarter and firm purchase orders released in that quarter by customers under agreements containing non-binding purchase commitments. Furthermore, a majority of customers typically require prompt delivery of products. This results in a limited backlog of orders for these products and requires us to maintain sufficient inventory levels to satisfy anticipated customer demand. If near-term demand for ADTRAN’s products declines, or if potential sales in any quarter do not occur as anticipated, our financial results could be adversely affected. Operating expenses are relatively fixed in the short term; therefore, a shortfall in quarterly revenues could impact ADTRAN’s financial results significantly in a given quarter. Further, maintaining sufficient inventory levels to assure prompt delivery of our products increases the amount of inventory that may become obsolete and increases the risk that the obsolescence of such inventory may have an adverse effect on our business and operating results.
 
ADTRAN’s operating results may also fluctuate as a result of a number of other factors, including increased competition, customer order patterns, changes in product mix, product warranty returns and announcements of new products by ADTRAN or our competitors. Accordingly, our historical financial performance is not necessarily a meaningful indicator of future results, and, in general, we expect that our financial results may vary from period to period.
 
Critical Accounting Policies
 
We believe the following critical accounting policies, among others, affect our more significant judgments and estimates used in the preparation of our financial statements:
 
 
 
We review customer contracts to determine if all of the requirements for revenue recognition have been met prior to recording revenues from sales transactions. We generally record sales revenue upon shipment of our products, net of any discounts, since: (i) we generally do not have significant post-delivery obligations, (ii) the product price is fixed and determinable, (iii) collection of the resulting receivable is probable, and (iv) product returns are reasonably estimable. We generally ship products upon receipt of a purchase order from a customer. We evaluate shipping terms and we record revenue on products shipped in accordance with the applicable terms of each respective contract.
 
 
 
We maintain allowances for doubtful accounts for losses resulting from the inability of our customers to make required payments. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, we may be required to make additional allowances.
 
 
 
We provide for the estimated cost of product warranties at the time revenue is recognized. While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers, our warranty obligation is affected by product

13


Table of Contents
failure rates, material usage and other rework costs incurred in correcting a product failure. Should actual product failure rates, material usage or other rework costs differ from our estimates, we may need to revise the estimated warranty liability.
 
 
 
We write down our inventory for estimated obsolescence or unmarketable inventory by an amount equal to the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual future demand or market conditions are less favorable than those projected by management, we may be required to make additional inventory write-downs.
 
 
 
We hold minority interests in publicly traded companies whose share prices may be volatile. We record an investment impairment charge when we believe an investment has experienced a decline in value that is other-than-temporary. Future adverse changes in market conditions or poor operating results of underlying investments could result in losses or an inability to recover the carrying value of the investments that may not be reflected in an investment’s current carrying value, thereby possibly requiring an impairment charge in the future.
 
Results of Operations—Three and Six Months Ended June 30, 2002 Compared to Three and Six Months Ended June 30, 2001
 
Sales
 
ADTRAN’s sales decreased 11.7% from $97,197,873 in the three months ended June 30, 2001 to $85,784,365 in the three months ended June 30, 2002. Sales decreased 16.5% from $202,473,620 in the six months ended June 30, 2001 to $169,126,348 in the six months ended June 30, 2002. The decrease was primarily the result of decreased spending by our customers, which we believe to be a result of both economic and industry-wide factors. Carrier Network sales decreased from $60,252,677 in the three months ended June 30, 2001 to $53,063,870 in the three months ended June 30, 2002 and decreased from $129,470,337 in the six months ended June 30, 2001 to $106,397,261 in the six months ended June 30, 2002. Carrier Network sales as a percentage of total sales remained relatively constant at 62.0% in the three months ended June 30, 2002 and 2001 and decreased from 63.9% for the six months ended June 30, 2001 to 62.9% in the six months ended June 30, 2002. Enterprise Network sales decreased from $36,945,196 in the three months ended June 30, 2001 to $32,720,495 for the three months ended June 30, 2002 and decreased from $73,003,283 in the six months ended June 30, 2001 to $62,729,087 in the six months ended June 30, 2002. Enterprise Network sales as a percentage of total sales remained relatively constant at 38.0% for the three months ended June 30, 2002 and 2001 and increased from 36.1% in the six months ended June 30, 2001 to 37.1% in the six months ended June 30, 2002. Foreign sales decreased 11.8% from $5,767,521 in the three months ended June 31, 2001 to $5,084,843 in the three months ended June 30, 2002 and increased 2.6% from $9,416,350 in the six months ended June 30, 2001 to $9,658,527 in the six months ended June 30, 2002.
 
Cost of Sales
 
Cost of sales decreased 14.5% from $51,639,324 in the three months ended June 30, 2001 to $44,161,128 in the three months ended June 30, 2002 and decreased 20.9% from $111,480,633 in the six months ended June 30, 2001 to $88,144,281 in the six months ended June 30, 2002. The cost of sales decrease quarter over quarter is primarily related to the decrease in revenues in each respective period. As a percentage of sales, cost of sales decreased from 53.1% in the three months ended June 30, 2001 to 51.5% in the three months ended June 30, 2002 and decreased from 55.1% in the six months ended June 30, 2001 to 52.1% in the six months ended June 30, 2002. An important part of ADTRAN’s strategy is to reduce the product

14


Table of Contents
 
cost of each succeeding product generation and then to lower the product’s price based on the cost savings achieved. This strategy, as described above, sometimes results in variations in ADTRAN’s gross profit margin due to timing differences between the recognition of cost reductions and the lowering of product selling prices. In view of the rapid pace of new product introductions by ADTRAN, this strategy may result in variations in gross profit margins that, for any particular financial period, can be difficult to predict.
 
Selling, General and Administrative Expenses
 
Selling, general and administrative expenses decreased 18.4% from $24,837,935 in the three months ended June 30, 2001 to $20,275,908 in the three months ended June 30, 2002 and decreased 19.3% from $50,902,771 in the six months ended June 30, 2001 to $41,065,730 in the six months ended June 30, 2002. This decrease is a result of a reduction in force, mandatory salary reductions, and other cost reductions implemented in the second half of 2001. Selling, general and administrative expenses as a percentage of sales decreased from 25.6% in the three months ended June 30, 2001 to 23.6% in the three months ended June 30, 2002 and decreased from 25.1% in the six months ended June 30, 2001 to 24.3% in the six months ended June 30, 2002. Nevertheless, selling, general and administrative expenses as a percent of sales will generally fluctuate whenever there is significant fluctuation in revenues during the periods being compared.
 
Research and Development Expenses
 
Research and development expenses decreased 1.9% from $14,925,049 in the three months ended June 30, 2001 to $14,637,503 in the three months ended June 30, 2002 and decreased 4.4% from $29,773,763 in the six months ended June 30, 2001 to $28,471,764 in the six months ended June 30, 2002. ADTRAN continually evaluates new product opportunities and engages in intensive research and product development efforts. To date, ADTRAN has expensed all product research and development costs as incurred. As a result, ADTRAN may incur significant research and development expenses prior to the receipt of revenues from a major new product group. As a percentage of sales, research and development expenses increased from 15.4% in the three months ended June 30, 2001 to 17.1% in the three months ended June 30, 2002 and increased from 14.7% in the six months ended June 30, 2001 to 16.8% in the six months ended June 30, 2002. ADTRAN will continue to incur research and development expenses in connection with its new products and its expansion into international markets. Research and development expenses as a percent of sales will fluctuate whenever there is a significant fluctuation in revenues during the periods being compared.
 
Interest Expense
 
Interest expense increased 30.5% from $478,639 in the three months ended June 30, 2001 to $624,725 in the three months ended June 30, 2002 and increased 33.9% from $982,194 in the six months ended June 30, 2001 to $1,315,008 in the six months ended June 30, 2002. This increase is primarily related to an increase in the interest rate on our $50,000,000 revenue bond, the proceeds of which were used to expand our facilities in Huntsville, Alabama.
 
Net Realized Investment Loss
 
Net realized investment loss increased from $135,231 in the three months ended June 30, 2001 to $1,365,136 in the three months ended June 30, 2002 and increased from $94,625 in the six months ended June 30, 2001 to $1,363,215 in the six months ended June 30, 2002. This increase is primarily related to the other-than-temporary investment impairment that was recognized in the second quarter of 2002. We recorded $1,336,242 of other-than-temporary investment impairment charges during the second quarter of 2002 related to four equity security investments.

Other Income
 
Other income increased 12.1% from $1,843,454 in the three months ended June 30, 2001 to $2,066,711 in the three months ended June 30, 2002 and increased 7.0% from $3,783,635 in the six months ended June 30, 2001 to $4,049,046 in the six months ended June 30, 2002. This increase is primarily related to an increase in investments and related investment income and an increase in the interest rate earned on the collateral deposit associated with $50,000,000 revenue bond.
 
Income Taxes
 
Our effective tax rate decreased from 34% for the six months ended June 30, 2001 to 27.4% for the six months ended June 30, 2002. Our effective annual tax rate for the year ended December 30, 2001 was 27%. This decrease is primarily related to temporary differences resulting from a higher mix of non-taxable income and higher research and development tax credits as a percent of taxable income. ADTRAN also recorded $454,322 of deferred income tax benefit in the three months ended June 30, 2002 related to the other-than-temporary investment impairment charge. This resulted in an effective tax rate of 26.8% in the three months ended June 30, 2002.
 
Net Income
 
As a result of the above factors, net income increased 7.1% from $4,636,598 in the three months ended June 30, 2001 to $4,966,581 in the three months ended June 30, 2002. Net income increased 8.3% from $8,595,358 in the six months ended June 30, 2001 to $9,307,259 in the six months ended June 30, 2002. As a percentage of sales, net income increased from 4.8% in the three months ended June 30, 2001 to 5.8% in the three months ended June 30, 2002 and increased from 4.2% in the six months ended June 30, 2001 to 5.5% in the six months ended June 30, 2002.
 
Liquidity and Capital Resources
 
Fifty million dollars of the expansion of Phase III of our corporate headquarters was approved for participation in an incentive program offered by the Alabama State Industrial Development Authority (the “Authority”). The incentive program enables participating companies to generate Alabama corporate income tax credits that can be used to reduce the amount of Alabama corporate income taxes that would otherwise be payable. We cannot assure you that the State of Alabama will continue to make these corporate income tax credits available in the future, and therefore, we may not realize the full benefit of these incentives. Through June 30, 2002, the Authority had issued $50,000,000 of its taxable revenue bonds pursuant to the incentive program and loaned the proceeds from the sale of the bonds to ADTRAN. We are required to make payments to the Authority in the amounts necessary to pay the principal of and interest on the Authority’s Taxable Revenue Bond, Series 1995, as amended, currently outstanding in the aggregate principal amount of $50,000,000. The bond matures on January 1, 2020, and bears interest at the rate of 20 basis points over the money market account-based rate of First Union National Bank. Included in long-term investments is $50,000,000 of restricted funds, which is a collateral deposit against the principal of this bond.
 
ADTRAN’s working capital position decreased 20.5% from $217,387,000 as of December 31, 2001 to $172,720,000 as of June 30, 2002. The quick ratio decreased from 6.32 as of December 31, 2001 to 4.71 as of June 30, 2002 and the current ratio decreased from 9.18 as of December 31, 2001 to 6.47 as of June 30, 2002. The decrease in working capital and related ratios is primarily a result of shifting investments from short-term to long-term. Accounts receivable and other receivables decreased 18.6% and 40.9%, respectively from December 31, 2001 to June 30, 2002 due to reduced sales volumes and improved collections. Average accounts receivable turnover improved 8 days from 60 days as of December 31, 2001 to 52 days as of June 30, 2002. ADTRAN has used, and expects to continue to use, the cash generated

from operations for working capital and other general corporate purposes, including (i) product development activities to enhance its existing products and develop new products and (ii) expansion of sales and marketing activities. Inventory decreased 27.4% from $56,849,000 as of December 31, 2001 to $41,244,000 as of June 30, 2002. Annualized inventory turnover increased from 2.92 turns as of December 31, 2001 to 3.59 turns as of June 30, 2002. The decrease in inventory is attributable to our continued efforts to streamline our production process and increase manufacturing velocity. Accounts payable increased 19.7% from December 31, 2001 to June 30, 2002. This increase is primarily related to obtaining more favorable payment terms with a significant supplier.
 
In July 2001, the Board of Directors approved the re-purchase of 2,000,000 shares of ADTRAN common stock. As of June 30, 2002, we had re-purchased 589,000 shares of our common stock at a total cost of $11,457,279.
 
Capital expenditures totaling $13,216,000 for the year ended December 31, 2001 were used to expand our headquarters and purchase equipment. Capital expenditures totaling $1,453,402 for the six months ended June 30, 2002 were used to purchase equipment.
 
At June 30, 2002, ADTRAN’s cash on hand of $74,481,644 and short-term investments of $25,284,358 placed our short-term cash availability at $99,766,002. At December 31, 2001, cash on hand was $81,280,409 and short-term investments were $26,282,961, which placed our short-term cash availability at $107,563,370.
 
At June 30, 2002, ADTRAN’s long-term investments increased by 23.1% to $194,355,154 from $157,901,718 at December 31, 2001. This increase was attributable to ADTRAN’s ability to generate cash from operations during the first six months of 2002 and our transfer of cash in excess of operational requirements to long term investments. Long-term investments at June 30, 2002 and December 31, 2001 include a restricted balance of $50,000,000 related to the revenue bonds as discussed above.
 
Investment Policy
 
The objective of our short-term investment policy is to preserve principal and maintain adequate liquidity with appropriate diversification, while emphasizing market returns on the our monetary assets.
 
The objective of our long-term investment policy is to emphasize total return; that is, the aggregate return from capital appreciation, dividend income and interest income. This is achieved through conservative investments and appropriate diversification in fixed and variable rate income, public equity, and private equity portfolios.
 
We review our investment portfolio for potential “other-than-temporary” declines in value on an individual investment basis. We assess on a quarterly basis significant declines in value which may be considered other-than-temporary and, if necessary, recognize and record the appropriate charge to write down the carrying value of such investments. In making this assessment, we take into consideration a wide range of objective and subjective information, including but not limited to the following: the magnitude and duration of historical decline in market prices, credit rating activity, assessments of liquidity, public filings and statements made by the issuer. Actual losses, if any, could ultimately differ from these estimates.
 
We intend to finance our operations in the future with cash flow from operations and remaining borrowed taxable revenue bond proceeds. We believe these available sources of funds to be adequate to meet our operating and capital needs for the foreseeable future.

Forward Looking Statements
 
The Private Securities Litigation Reform Act of 1995 (the “Reform Act”) provides a safe harbor for forward-looking statements made by or on behalf of ADTRAN. ADTRAN and its representatives may from time to time make written or verbal forward-looking statements, including statements contained in this report and our other filings with the Securities and Exchange Commission and in our reports to our stockholders. Generally, the words, “believe,” “expect,” “intend,” “estimate,” “anticipate,” “will,” “may,” “could” and similar expressions identify forward-looking statements. We caution you that any forward-looking statements made by or on our behalf are subject to uncertainties and other factors that could cause such statements to be wrong. Some of these uncertainties and other factors are listed below. They have been discussed in our most recent Form 10-K filed on March 29, 2002 with the SEC as well as in prior SEC filings. Though we have attempted to list comprehensively these important factors, we caution investors that other factors may prove to be important in the future in affecting our operating results. New factors emerge from time to time, and it is not possible for us to predict all of these factors, nor can we assess the impact each factor or combination of factors may have on our business. You are further cautioned not to place undue reliance on those forward-looking statements because they speak only of our views as of the date the statements were made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
 
The following are some of the risks that could affect our financial performance or could cause actual results to differ materially from those expressed or implied in our forward-looking statements:
 
 
 
We must continue to update and improve our products and develop new products in order to compete and to keep pace with improvements in telecommunications technology.
 
 
 
Our dependence on a limited number of suppliers may prevent us from delivering our products on a timely basis, which could have a material adverse effect on customer relations and operating results.
 
 
 
Our dependence on subcontractors may result in reduced control over product quality, delayed delivery of products and/or increased manufacturing costs, each of which could negatively affect customer relations and operating results.
 
 
 
We compete in markets that have become increasingly competitive, which may result in reduced gross profit margins and market share.
 
 
 
We depend heavily on sales to certain customers; the loss of any of these customers would significantly reduce our revenues and net income.
 
 
 
The lengthy approval process required by the RBOCs and other carriers could result in fluctuations in our revenues.
 
 
 
Consolidation in the Competitive Service Provider market could result in a significant decrease in our revenue.
 
 
 
Increased sales volume in international markets could result in increased costs or loss of revenue due to factors inherent in these markets.
 
 
 
Our success depends on our ability to reduce the selling prices of succeeding generations of our products.
 
 
 
Our failure to adequately protect our intellectual property rights could adversely affect the development and commercialization of our products.
 
 
 
Two stockholders own or may influence a significant amount of our common stock and may continue to have significant influence on our affairs.
 
 
 
The price of our common stock has been volatile and may continue to fluctuate substantially.
 
The foregoing list of risks is not exclusive.
