Summary of Significant Accounting Policies
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation
The accompanying unaudited consolidated financial statements of ADTRAN®, Inc. and its subsidiaries (ADTRAN) have been prepared pursuant to the rules and regulations for reporting on Quarterly Reports on Form 10-Q. Accordingly, certain information and notes required by generally accepted accounting principles for complete financial statements are not included herein. The December 31, 2010 Consolidated Balance Sheet is derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States.
In the opinion of management, all adjustments necessary for a fair presentation of these interim statements have been included and are of a normal and recurring nature. The results of operations for an interim period are not necessarily indicative of the results for the full year. The interim statements should be read in conjunction with the financial statements and notes thereto included in ADTRAN’s Annual Report on Form 10-K for the year ended December 31, 2010, filed on February 25, 2011 with the SEC.
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Our more significant estimates include the allowance for doubtful accounts, obsolete and excess inventory reserves, warranty reserves, customer rebates, allowance for sales returns, estimated income tax contingencies, the fair value of stock-based compensation, and the evaluation of other-than-temporary declines in the value of investments. Actual amounts could differ significantly from these estimates.
Recent Accounting Pronouncements
During the first quarter of 2011, we adopted the following accounting standards, which had no material effect on our consolidated results of operations or financial condition:
In October 2009, the Financial Accounting Standards Board (FASB) issued Update No. 2009-13, which amends the Revenue Recognition topic of the FASB Accounting Standards Codification (ASC). This update provides amendments to the criteria in Subtopic 605-25 of the ASC for separating consideration in multiple-deliverable arrangements. As a result of those amendments, multiple-deliverable arrangements will be separated in more circumstances than under existing U.S. GAAP. The amendments establish a selling price hierarchy for determining the selling price of a deliverable and will replace the term fair value in the revenue allocation guidance with selling price to clarify that the allocation of revenue is based on entity-specific assumptions rather than assumptions of a marketplace participant. The amendments will also eliminate the residual method of allocation and require that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method and will require that a vendor determine its best estimate of selling price in a manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis.
We generally sell our products and services separately, but in some circumstances products and services may be sold in bundles that contain multiple deliverables. A sale that includes multiple deliverables is evaluated to determine the units of accounting, and the revenue from the arrangement is allocated to each item requiring separate revenue recognition based on the relative selling price and corresponding terms of the contract. We strive to use vendor-specific objective evidence of selling price. When this evidence is not available, we are generally not able to determine third-party evidence of selling price because of the extent of customization among competing products or services from other companies. In these cases, estimated selling price is determined based on the particular circumstances of the arrangement and is used to allocate revenues to each unit of accounting. Revenue is recognized incrementally as the necessary criteria for each item is met.
We adopted this guidance for the three months ended March 31, 2011. The adoption of this guidance had no effect on our consolidated results of operations and financial condition for the three months ended March 31, 2011.
In October 2009, the FASB issued Update No. 2009-14, which amends the Software topic of the ASC. The amendments in this update change the accounting model for revenue arrangements that include both tangible products and software elements. Tangible products containing software components and non-software components that function together to deliver the tangible product’s essential functionality is no longer within the scope of the software revenue guidance in Subtopic 985-605 of the ASC. In addition, the amendments in this update require that hardware components of a tangible product containing software components always be excluded from the software revenue guidance. In that regard, the amendments provide additional guidance on how to determine which software, if any, relating to the tangible product also would be excluded from the scope of the software revenue guidance. The amendments also provide guidance on how a vendor should allocate arrangement consideration to deliverables in an arrangement that includes both tangible products and software. The amendments also provide further guidance on how to allocate arrangement consideration when an arrangement includes deliverables both included and excluded from the scope of the software revenue guidance. We adopted this guidance for the three months ended March 31, 2011. The adoption of this guidance had no effect on our consolidated results of operations and financial condition for the three months ended March 31, 2011.
Income Taxes
INCOME TAXES
2. INCOME TAXES
Our effective tax rate decreased from 35.7% in the three months ended March 31, 2010 to 30.7% in the three months ended March 31, 2011. The decrease is primarily due to the research and development tax credit and increased tax benefits from a higher volume of stock option exercises during the first quarter of 2011. The tax provision rate in the first quarter of 2010 did not include the benefit of the research and development tax credit, which expired on December 31, 2009. The credit was reinstated during the fourth quarter of 2010. The inclusion of this benefit in the first quarter of 2011 resulted in a 2.2 percentage point decrease in our tax rate. Also, increased benefits from a higher volume of stock option exercises in the first quarter of 2011 resulted in a 3.9 percentage point decrease in our tax rate.
Stock-Based Compensation
STOCK-BASED COMPENSATION
3. STOCK-BASED COMPENSATION
The following table summarizes the stock-based compensation expense related to stock options, restricted stock units (RSUs) and restricted stock under the Stock Compensation Topic of the FASB ASC for the three months ended March 31, 2011 and 2010, which was recognized as follows:

Total stock-based compensation expense, net of tax
  $ 1,649     $ 1,512  
 
           
The fair value of our stock options was estimated using the Black-Scholes model. The determination of the fair value of stock options on the date of grant using the Black-Scholes model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables that may have a significant impact on the fair value estimate.
There were no options granted during the three month period ended March 31, 2011. The weighted-average assumptions and value of options granted for the three months ended March 31, 2010 are summarized as follows:
                 
    Three Months Ended  
    March 31,  
    2011     2010  
Expected volatility
          41.29 %
Risk-free interest rate
          2.52 %
Expected dividend yield
          1.59 %
Expected life (in years)
          5.22  
Weighted-average estimated value
  $     $ 7.86  
The fair value of our RSUs is calculated using a Monte Carlo Simulation valuation method. There were no RSU grants during the three months ended March 31, 2011 or 2010.
The fair value of restricted stock is equal to the closing price of our stock on the date of grant. There were no restricted stock grants during the three months ended March 31, 2011 or 2010.
Stock-based compensation expense recognized in our Consolidated Statements of Income for the three months ended March 31, 2011 and 2010 is based on options, RSUs and restricted stock ultimately expected to vest, and has been reduced for estimated forfeitures. Estimated forfeitures for stock options were based upon historical experience and approximate 2.0% annually. We estimated a 0% forfeiture rate for our RSUs and restricted stock due to the limited number of recipients and historical experience for these awards.
As of March 31, 2011, total compensation expense related to non-vested stock options, RSUs and restricted stock not yet recognized was approximately $18.1 million, which is expected to be recognized over an average remaining recognition period of 2.9 years.
The following table is a summary of our stock options outstanding as of December 31, 2010 and March 31, 2011 and the changes that occurred during the three months ended March 31, 2011:

The aggregate intrinsic values in the table above represent the total pre-tax intrinsic value (the difference between ADTRAN’s closing stock price on the last trading day of the quarter and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2011. The aggregate intrinsic value will change based on the fair market value of ADTRAN’s stock.
The total pre-tax intrinsic value of options exercised during the three month period ended March 31, 2011 was $37.4 million.
The following table is a summary of our RSUs and restricted stock outstanding as of December 31, 2010 and March 31, 2011 and the changes that occurred during the three months ended March 31, 2011:

At March 31, 2011, we held $6.6 million of deferred compensation plan assets, carried at fair value.
At March 31, 2011, we held $184.1 million of corporate bonds. These bonds are classified as available-for-sale and had an average duration of 2.3 years at March 31, 2011. At March 31, 2011, approximately 1% of our corporate bond portfolio had a credit rating of AAA, 16% had a credit rating of AA, 52% had a credit rating of A, and 31% had a credit rating of BBB.
At March 31, 2011, we held $134.0 million of municipal fixed-rate bonds. These bonds are classified as available-for-sale and had an average duration of 1.5 years at March 31, 2011. At March 31, 2011, approximately 21% of our municipal fixed-rate bond portfolio had a credit rating of AAA, 64% had a credit rating of AA, and 15% had a credit rating of A. Because our bond portfolio has a high quality rating and contractual maturities of a short duration, we are able to obtain prices for these bonds derived from observable market inputs, or for similar securities traded in an active market, on a daily basis.
At March 31, 2011, we held $58.7 million of municipal variable rate demand notes, all of which were classified as available-for-sale. At March 31, 2011, 30% of our municipal variable rate demand notes had a credit rating of AAA, 55% had a credit rating of AA, 15% had a credit rating of A, and all contained put options of seven days. Despite the long-term nature of their stated contractual maturities, we routinely buy and sell these securities and we believe that we have the ability to quickly liquidate them. Our investments in these securities are recorded at fair value, and the interest rates reset every seven days. We believe we have the ability to sell our variable rate demand notes to the remarketing agent, tender agent or issuer at par value plus accrued interest in the event we decide to liquidate our investment in a particular variable rate demand note. At March 31, 2011, approximately 38% of our variable rate demand notes were supported by letters of credit from banks that we believe to be in good financial condition. The remaining 62% of our variable rate demand notes were supported by standby purchase agreements. As a result of these factors, we had no cumulative gross unrealized holding gains (losses) or gross realized gains (losses) from these investments. All income generated from these investments was recorded as interest income. We have not recorded any losses relating to municipal variable rate demand notes.
At March 31, 2011, we held $0.8 million of a fixed income bond fund.
At March 31, 2011, we held $44.8 million of marketable equity securities, including a single security, of which we held 1.4 million shares, carried at a fair value of $29.8 million. We sold 93 thousand shares of this security during the three months ended March 31, 2011. The sale of this security resulted in proceeds of $2.1 million and a realized gain of $2.0 million. This single security traded approximately 1.1 million shares per day in the first quarter of 2011 in an active market on a European stock exchange. This single security comprises $29.3 million of the gross unrealized gains included in the fair value of our marketable equity securities at March 31, 2011. The remaining $3.7 million of gross unrealized gains and $0.1 million of gross unrealized losses at March 31, 2011 were spread amongst more than 400 equity securities.
At March 31, 2011, we held a $48.3 million restricted certificate of deposit, which is carried at cost. This investment serves as a collateral deposit against the principal amount outstanding under loans made to ADTRAN pursuant to an Alabama State Industrial Development Authority revenue bond (the Bond). At March 31, 2011, the estimated fair value of the Bond was approximately $43.7 million, based on a debt security with a comparable interest rate and maturity and a Standard and Poor’s credit rating of A+. We have the right to set-off the balance of the Bond with the collateral deposit in order to reduce the balance of the indebtedness. For more information on the Bond, see “Debt” under “Liquidity and Capital Resources” in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Item 2 of Part I of this report.
At March 31, 2011, we held $2.1 million of other investments carried at cost, consisting of interests in two private equity funds and an investment in a privately held telecommunications equipment manufacturer. The fair value of these investments was estimated to be approximately $10.8 million at March 31, 2011, based on unobservable inputs including information supplied by the company and the fund managers. We have committed to invest up to an aggregate of $7.9 million in the two private equity funds, and we have contributed $8.0 million as of March 31, 2011, of which $7.4 million has been applied toward these commitments. As of March 31, 2011, we have received distributions related to these two private equity funds of $7.2 million, of which $0.9 million was recorded as investment income. These investments are carried at cost, net of distributions, with distributions in excess of our investment recorded as investment income. The duration of each of these commitments is ten years with $0.4 million expiring in 2013 and $0.1 million expiring in 2012. We have not been required to record any impairment losses related to these investments during the three months ended March 31, 2011.
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 qualitative and quantitative information, including but not limited to the following: the magnitude and duration of historical declines in market prices, credit rating activity, assessments of liquidity, public filings, and statements made by the issuer. We generally begin our identification of potential other-than-temporary impairments by reviewing any security with a fair value that has declined from its original or adjusted cost basis by 25% or more for six or more consecutive months. We then evaluate the individual security based on the previously identified factors to determine the amount of the write-down, if any. As a result of our review, we recorded an other-than-temporary impairment charge of $4 thousand during the first quarter of 2011 related to one marketable equity security. For the three months ended March 31, 2010, we recorded an other-than-temporary impairment charge of $2 thousand related to one marketable equity security.
In accordance with the Fair Value Measurements and Disclosures Topic of the FASB ASC, we have categorized our cash equivalents held in money market funds and our investments held at fair value into a three-level fair value hierarchy based on the priority of the inputs to the valuation technique for the cash equivalents and investments as follows: Level 1 — Values based on unadjusted quoted prices for identical assets or liabilities in an active market; Level 2 — Values based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly; Level 3 — Values based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs include information supplied by investees.

As of March 31, 2011 and December 31, 2010, the fair value of the investments in available-for-sale Level 2 corporate bonds and municipal fixed-rate bonds was $318.2 million and $198.5 million, respectively. The fair value of these securities is calculated using a weighted average market price for each security. Market prices are obtained from a variety of industry standard data providers, security master files from large financial institutions, and other third-party sources. These multiple market prices are used as inputs into a distribution-curve-based algorithm to determine the daily market value of each security.
As of March 31, 2011 and December 31, 2010, the fair value of the investments in available-for-sale Level 2 municipal variable rate demand notes was $58.7 million and $116.7 million, respectively. These securities have a structure that implies a standard expected market price. The frequent interest rate resets make it reasonable to expect the price to stay at par. These securities are priced at the expected market price.

Segment Information
SEGMENT INFORMATION
8. SEGMENT INFORMATION
We operate in two reportable segments: (1) the Carrier Networks Division and (2) the Enterprise Networks Division. We evaluate the performance of our segments based on gross profit; therefore, selling, general and administrative expenses, research and development expenses, interest and dividend income, interest expense, net realized investment gain/loss, other expense, net and provision for income taxes are reported on an entity-wide basis only. There are no inter-segment revenues.
The following table presents information about the reported sales and gross profit of our reportable segments for the three months ended March 31, 2011 and 2010.

Liability For Warranty Returns
LIABILITY FOR WARRANTY RETURNS
9. LIABILITY FOR WARRANTY RETURNS
Our products generally include warranties of one to ten years for product defects. We accrue for warranty returns at the time revenue is recognized based on our estimate of the cost to repair or replace the defective products. We engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Our products continue to become more complex in both size and functionality as many of our product offerings migrate from line card applications to systems products. The increasing complexity of our products will cause warranty incidences, when they arise, to be more costly. Our estimates regarding future warranty obligations may change due to product failure rates, material usage, and other rework costs incurred in correcting a product failure. In addition, from time to time, specific warranty accruals may be recorded if unforeseen problems arise. Should our actual experience relative to these factors be worse than our estimates, we will be required to record additional warranty expense. Alternatively, if we provide for more reserves than we require, we will reverse a portion of such provisions in future periods. The liability for warranty obligations totaled $3.5 million at March 31, 2011 and $3.3 million at December 31, 2010. These liabilities are included in accrued expenses in the accompanying Consolidated Balance Sheets.
A summary of warranty expense and write-off activity for the three months ended March 31, 2011 and 2010 is as follows:

We employ the law firm of our director emeritus for legal services. All bills for services rendered by this firm are reviewed and approved by our Chief Financial Officer. We believe that the fees for such services are comparable to those charged by other firms for services rendered to us. For the three months ended March 31, 2011 and 2010, we incurred fees of $10 thousand per month for these legal services.
Commitments and Contingencies
COMMITMENTS AND CONTINGENCIES
11. COMMITMENTS AND CONTINGENCIES
In the ordinary course of business, we may be subject to various legal proceedings and claims, including employment disputes, patent claims, disputes over contract agreements and other commercial disputes. In some cases, claimants seek damages or other relief, such as royalty payments related to patents, which, if granted, could require significant expenditures. Although the outcome of any claim or litigation can never be certain, it is our opinion that the outcome of all contingencies of which we are currently aware will not materially affect our business, operations, financial condition or cash flows.
We have committed to invest up to an aggregate of $7.9 million in two private equity funds, and we have contributed $8.0 million as of March 31, 2011, of which $7.4 million has been applied to these commitments. See Note 4 of Notes to Consolidated Financial Statements for additional information.
Subsequent Events
SUBSEQUENT EVENTS
12. SUBSEQUENT EVENTS
On April 12, 2011, we announced that our Board of Directors declared a quarterly cash dividend of $0.09 per common share to be paid to stockholders of record at the close of business on April 28, 2011. The payment date will be May 12, 2011. The quarterly dividend payment will be approximately $5.8 million. In July 2003, our Board of Directors elected to begin declaring quarterly dividends on our common stock considering the tax treatment of dividends and adequate levels of Company liquidity.
