The accompanying unaudited condensed consolidated financial statements, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) which Harmonic Inc. (“Harmonic,” or the “Company”) considers necessary for a fair statement of the results of operations for the interim periods covered and the consolidated financial condition of the Company at the date of the balance sheets. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K, which was filed with the Securities and Exchange Commission on February 28, 2014 (“2013 Form 10-K”). The interim results presented herein are not necessarily indicative of the results of operations that may be expected for the full fiscal year ending December 31, 2014, or any other future period. The Company’s fiscal quarters are based on 13-week periods, except for the fourth quarter, which ends on December 31. | |
The condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The year-end condensed balance sheet was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“US GAAP”). | |
Discontinued Operations | |
In the first quarter of fiscal 2013, the Company completed the sale of its cable access hybrid-fiber coaxial ("HFC") business to Aurora Networks (“Aurora”). The results of operations associated with the cable access HFC business were presented as discontinued operations in its unaudited condensed consolidated financial statements as described in Note 3, "Discontinued Operations". There were no operating activities associated with the cable access HFC business after December 31, 2013. Unless noted otherwise, all discussions herein with respect to the Company’s unaudited condensed consolidated financial statements relate to the Company’s continuing operations. | |
Use of Estimates | |
The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. | |
Significant Accounting Policies | |
The Company’s significant accounting policies are described in Note 2 to its audited Consolidated Financial Statements included in its 2013 Form 10-K. There have been no significant changes to these policies during the three months ended March 28, 2014. |

RECENT ACCOUNTING PRONOUNCEMENTS | |
In March 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”. The ASU addresses accounting for a cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new guidance became effective for the Company beginning in the first quarter of fiscal 2014 and it did not have a material impact on the Company’s Consolidated Financial Statements. | |
In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. Under certain circumstances, unrecognized tax benefits should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The new guidance became effective for the Company beginning in the first quarter of fiscal 2014 and it did not have a material impact on the Company’s Consolidated Financial Statements. | |
On April 10, 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance is effective for the Company beginning in the first quarter of fiscal 2015. The Company does not expect the adoption of ASU 2014-08 will have a material impact on its financial position, results of operations or cash flows. |

DISCONTINUED OPERATIONS | ||||||||
In February 2013, the Company entered into an Asset Purchase Agreement with Aurora pursuant to which the Company agreed to sell its cable access HFC business for $46.0 million in cash. On March 5, 2013, the sale transaction closed and the Company received gross proceeds of $46.0 million from the sale and recorded a net gain of $15.0 million in connection with the sale in the first quarter of fiscal 2013. The gain was included in income from discontinued operations, net of tax in the Condensed Consolidated Statement of Operations for the three months ended March 29, 2013. | ||||||||
In March 2013, the Company entered into a transition services agreement (‘TSA”) with Aurora to provide contract manufacturing and other various support, including providing order fulfillment, taking warranty calls, attending to product returns from customers, providing cost accounting analysis, receiving payments from customers and remitting such payments to Aurora. The TSA fees were a fixed amount per month and were determined based on the Company’s estimated cost of delivering the transition services. In addition, in April 2013, the Company and Aurora signed a sublease agreement for the Company’s Milpitas warehouse for the remaining period of the lease. | ||||||||
The TSA ended in October 2013 and the billing to Aurora was recorded in the Condensed Consolidated Statements of Operations under income from continuing operations as an offset to the expenses incurred to deliver the transition services. The table below provides details on the income statement caption under which the TSA billing was recorded (in thousands): | ||||||||

The Company recorded a gain of $15.0 million in the three months ended March 29, 2013, in connection with the sale of the cable access HFC business, calculated as follows (in thousands): | ||||||||
Gross Proceeds | $ | 46,000 | ||||||

Less : Selling cost | $ | 2,469 | ||||||
Less : Tax effect | $ | 7,234 | ||||||
Gain on disposal, net of taxes | $ | 14,956 | ||||||
Since the Company has one reporting unit, upon the sale of the cable access HFC business, approximately $14.5 million of the carrying value of goodwill was allocated to the cable access HFC business based on the relative fair value of the cable access HFC business to the fair value of the Company. The remaining carrying value of goodwill was tested for impairment, and the Company determined that goodwill was not impaired as of March 29, 2013. | ||||||||
The results of operations associated with the cable access HFC business are presented as discontinued operations in the Company’s Condensed Consolidated Statements of Operations for fiscal 2013. There were no operating activities associated with the cable access HFC business after December 31, 2013. Revenue and the components of net income related to the discontinued operations for the three months ended March 29, 2013 were as follows: | ||||||||

Realized gains and losses from the sale of investments for the three months ended March 28, 2014 and March 29, 2013 were not material. | ||||||||||||||||
Impairment of Investments | ||||||||||||||||
The Company monitors its investment portfolio for impairment on a periodic basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis for the investment is established. A decline of fair value below amortized costs of debt securities is considered other-than-temporary if the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis. At the present time, the Company does not intend to sell its investments that have unrealized losses in accumulated other comprehensive loss. In addition, the Company does not believe that it is more likely than not that it will be required to sell its investments that have unrealized losses in accumulated other comprehensive loss before the Company recovers the principal amounts invested. The Company believes that the unrealized losses are temporary and do not require an other-than-temporary impairment, based on its evaluation of available evidence as of March 28, 2014. | ||||||||||||||||
As of March 28, 2014, there were no individual available-for-sale securities in a material unrealized loss position and the amount of unrealized losses on the total investment balance was insignificant. |

Fair Value Measurements | ' | |||||||||||||||
FAIR VALUE MEASUREMENTS | ||||||||||||||||
The applicable accounting guidance establishes a framework for measuring fair value and requires disclosure about the fair value measurements of assets and liabilities. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as described below. | ||||||||||||||||
The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. | ||||||||||||||||
Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The guidance describes three levels of inputs that may be used to measure fair value: | ||||||||||||||||
• | Level 1 — Observable inputs that reflect quoted prices for identical assets or liabilities in active markets. | |||||||||||||||
• | Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company primarily uses broker quotes for valuation of its short-term investments. The forward exchange contracts are classified as Level 2 because they are valued using quoted market prices and other observable data for similar instruments in an active market. | |||||||||||||||
• | Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | |||||||||||||||
The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. During the three months ended March 28, 2014, there were no nonrecurring fair value measurements of assets and liabilities subsequent to initial recognition. | ||||||||||||||||

Harmonic 2013 Restructuring | ||||||||||||
In the first quarter of fiscal 2013, the Company committed to a restructuring plan to reduce costs and improve efficiencies. This restructuring plan extended to actions taken through the first quarter of fiscal 2014. In fiscal 2013, the Company recorded $2.2 million of restructuring charges under this plan consisting of worldwide workforce reductions, writing down leasehold improvements and furniture related to its Milpitas warehouse to estimated net realizable value, and obsolete inventory at its Israel facilities. The restructuring charges were included in “Product cost of revenue” and "Operating expenses-restructuring and related charges” in the Condensed Consolidated Statements of Operations. Of the $2.2 million restructuring charges in fiscal 2013, $565,000 was recorded in the three months ended March 29, 2013. For a complete discussion of the restructuring actions related to the 2013 restructuring plan, please refer to Note 9 of the Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2013. | ||||||||||||

CREDIT FACILITIES | |
Harmonic has a bank line of credit facility with Silicon Valley Bank that provides for borrowings of up to $10.0 million and matures on August 22, 2014. There were no borrowings during the three months ended March 28, 2014. As of March 28, 2014, the amount available for borrowing under this facility, net of $0.2 million of standby letters of credit, was $9.8 million. | |
This facility, which became effective in August 2011 and was amended in August 2012, contains a financial covenant that requires Harmonic to maintain a ratio of unrestricted cash, accounts receivable and short term investments to current liabilities (less deferred revenue) of at least 1.75 to 1.00. As of March 28, 2014, the Company’s ratio under that covenant was 4.33 to 1. In the event of noncompliance by Harmonic with the covenants under the facility, including the financial covenant referenced above, Silicon Valley Bank would be entitled to exercise its remedies under the facility, including declaring all obligations immediately due and payable. As of March 28, 2014, Harmonic was in compliance with the covenants under the line of credit facility. Borrowings pursuant to the line would bear interest at the bank’s prime rate (3.25% at March 28, 2014,) or at LIBOR for the desired borrowing period (an annualized rate of 0.15% for a one month borrowing period at March 28, 2014) plus 1.75%, or 1.90%. Borrowings are not collateralized. |

Employee Stock Purchase Plan | |||||||||||||||||
The 2002 Employee Stock Purchase Plan (“ESPP”) provides for the issuance of common stock purchase rights to employees of the Company. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The ESPP enables employees to purchase shares at 85% of the fair market value of the common stock at the beginning or end of the offering period, whichever is lower. Offering periods generally begin on the first trading day on or after January 1 and July 1 of each year. Employees may participate through payroll deductions of 1% to 10% of their earnings. In the event that there are insufficient shares in the plan to fully fund the issuance, the available shares will be allocated across all participants based on their contributions relative to the total contributions received for the offering period. | |||||||||||||||||
There was a shortage of approved shares in the ESPP to fund the total employee contributions from January 2, 2013 to June 30, 2013. The shares available in the plan were sufficient to fund approximately 53% of the total contributions. As a result, the shares available were issued ratably to the participants based on each of their contributions during the offering period, relative to the total contributions received from all participants. The participants were refunded the remaining 47% of their contributions and the ESPP was suspended for the second half of 2013. The Company’s stockholders approved a 1,000,000 share increase in the authorized shares for the ESPP during the Company’s annual meeting on August 14, 2013, and contributions under the ESPP resumed in January 2014. | |||||||||||||||||
401(k) Plan | |||||||||||||||||
Harmonic has a retirement/savings plan which qualifies as a thrift plan under Section 401(k) of the Internal Revenue Code. This plan allows participants to contribute up to the applicable Internal Revenue Code limitations under the plan. Harmonic has made discretionary contributions to the plan of 25% of the first 4% contributed by eligible participants, up to a maximum contribution per participant of $1,000 per year. Harmonic contributed $173,000 for both the three months ended March 28, 2014 and March 29, 2013. |

Total stock-based compensation | $ | 3,807 | $ | 3,899 | ||||
Stock Options | ||||||||
The Company estimated the fair value of all employee stock options using a Black-Scholes valuation model with the following weighted average assumptions: | ||||||||
Three months ended | ||||||||
March 28, | March 29, | |||||||
2014 | 2013 | |||||||
Expected term (years) | 4.7 | 4.7 | ||||||
Volatility | 40 | % | 52 | % | ||||
Risk-free interest rate | 1.7 | % | 0.8 | % | ||||
Expected dividends | 0 | % | 0 | % | ||||
The expected term represents the weighted-average period that the stock options are expected to remain outstanding. The computation of the expected term was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The Company uses its historical volatility for a period equivalent to the expected term of the options to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model. | ||||||||
The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. | ||||||||
The weighted-average fair value per share of options granted was $2.35 and $2.50 for the three months ended March 28, 2014 and March 29, 2013, respectively. | ||||||||
The fair value of all stock options vested during the three months ended March 28, 2014 and March 29, 2013 was $1,330,000 and $1,260,000, respectively. | ||||||||
The total realized tax benefit attributable to stock options exercised during the three months ended March 28, 2014, in jurisdictions where this expense is deductible for tax purposes, was $185,000. The Company did not recognize any tax benefit attributable to stock options exercised during the three months ended March 29, 2013. | ||||||||
Restricted Stock Units | ||||||||
The estimated fair value of all restricted stock units issued during the three months ended March 28, 2014 and March 29, 2013 was $5.4 million and $5.6 million, respectively. | ||||||||
Employee Stock Purchase Plan | ||||||||
The value of the stock purchase rights under the ESPP consists of: (1) the 15% discount on the purchase of the stock; (2) 85% of the fair value of the call option; and (3) 15% of the fair value of the put option. The call option and put option were valued using the Black-Scholes option pricing model. The weighted average fair value of the Company's ESPP shares at purchase dates was estimated using the following weighted average assumptions during the three months ended March 28, 2014 and March 29, 2013: | ||||||||
Purchase Period Ending | ||||||||
June 30, | June 30, | |||||||
2014 | 2013 | |||||||
Expected term (years) | 0.5 | 0.49 | ||||||
Volatility | 29 | % | 32 | % | ||||
Risk-free interest rate | 0.1 | % | 0.2 | % | ||||
Expected dividends | 0 | % | 0 | % | ||||
Estimated weighted average fair value per share at purchase date | $1.71 | $1.20 | ||||||
The expected term represents the period of time from the beginning of the offering period to the purchase date. The Company uses its historical volatility for a period equivalent to the expected term of the options to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model. | ||||||||
The ESPP was suspended for the second half of 2013 due to all authorized shares under the plan having been issued through the offering period ended June 30, 2013. The Company’s stockholders approved a 1,000,000 share increase in the authorized shares for the ESPP during the Company’s annual meeting on August 14, 2013, and contributions under the ESPP resumed in January 2014. As a result, the Company did not have any stock-based compensation expense in the second half of fiscal 2013 related to the ESPP. | ||||||||
Unrecognized Stock-Based Compensation | ||||||||
As of March 28, 2014, total unamortized stock-based compensation cost related to unvested stock options and restricted stock units was $23.9 million. This amount will be recognized as expense using the straight-line attribution method over the remaining weighted-average amortization period of 2.0 years. |

The Company reported the following operating results for the periods presented (in thousands): | ||||||||
Three months ended | ||||||||

Loss from continuing operations before income taxes | $ | (7,133 | ) | $ | (14,970 | ) | ||
Benefit from income taxes | $ | (1,723 | ) | $ | (5,467 | ) | ||
Effective income tax rate | 24.2 | % | 36.5 | % | ||||
The Company's quarterly income taxes reflect an estimate of the corresponding fiscal year's annual effective tax rate and include, where applicable, adjustments for discrete tax items. In the three months ended March 28, 2014, the Company's effective income tax rate was 24.2% as compared to 36.5% in the corresponding period of 2013, primarily due to the change in the mix of pretax income and losses in the various tax jurisdictions in which the Company operates. | ||||||||
The Company's effective rate for the three months ended March 28, 2014 is lower than the U.S. federal statutory rate of 35% primarily due to favorable tax rates associated with certain earnings from operations in lower-tax jurisdictions, partially offset by the detriment from non-deductible stock-based compensation and non-deductible amortization of foreign intangibles, and the net of various discrete tax adjustments. For the three months ended March 28, 2014, the discrete adjustments to the Company's tax benefit were primarily the accrual of interest on uncertain tax positions. | ||||||||
The Company files federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations during which such tax returns may be audited and adjusted by the relevant tax authorities. The U.S. Internal Revenue Service has concluded its audit for the 2008 and 2009 tax years. In addition, the statute of limitations on the Company's 2008 and 2009 U.S. corporate income tax return expired in September 2013 and, as a result, in the third quarter of 2013, the Company released the related tax reserves, including accrued interest and penalties, for those tax years. The 2010 through 2012 tax years generally remain subject to examination by U.S. federal and most state tax authorities and the statute of limitation for the 2010 tax year will be expiring in September 2014. In significant foreign jurisdictions, the 2006 through 2012 tax years generally remain subject to examination by their respective tax authorities. | ||||||||
The Company's operations in Switzerland are subject to a reduced tax rate under the Switzerland tax holiday which requires various thresholds of investment and employment in Switzerland. The Company has met these various thresholds and the Switzerland tax holiday is effective through the end of 2018. | ||||||||
As of March 28, 2014, the total amount of gross unrecognized tax benefits, including interest and penalties, was approximately $26.1 million, that if recognized, would affect the Company's effective tax rate. The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense. The Company had $1.7 million of gross interest and penalties accrued as of March 28, 2014. The Company will continue to review its tax positions and provide for, or reverse, unrecognized tax benefits as issues arise. As of March 28, 2014, the Company anticipates that the balance of gross unrecognized tax benefits will decrease up to approximately $10 million due to expiration of the applicable statues of limitations over the next 12 months. | ||||||||
The Company assesses the realizability of its deferred tax assets on a quarterly basis. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized.The Company believes, based on the quarterly assessment performed at March 28, 2014, that it is possible that a valuation allowance may be required in the future. |

Purchase Commitments with Contract Manufacturers and Other Suppliers | ||||||||
The Company relies on a limited number of contract manufacturers and suppliers to provide manufacturing services for a substantial majority of its products. In addition, some components, sub-assemblies and modules are obtained from a sole supplier or limited group of suppliers. During the normal course of business, in order to reduce manufacturing lead times and ensure adequate component supply, the Company enters into agreements with certain contract manufacturers and suppliers that allow them to procure inventory based upon criteria defined by the Company. The Company had approximately $26.1 million of non-cancelable purchase commitments with contract manufacturers and other suppliers as of March 28, 2014. | ||||||||
Standby Letters of Credit | ||||||||
As of March 28, 2014, the Company’s financial guarantees consisted of standby letters of credit outstanding, which were principally related to performance bonds and state requirements imposed on employers. The maximum amount of potential future payments under these arrangements was $0.2 million as of March 28, 2014. | ||||||||
Indemnification | ||||||||
Harmonic is obligated to indemnify its officers and the members of its Board of Directors pursuant to its bylaws and contractual indemnity agreements. Harmonic also indemnifies some of its suppliers and most of its customers for specified intellectual property matters pursuant to certain contractual arrangements, subject to certain limitations. The scope of these indemnities varies, but, in some instances, includes indemnification for damages and expenses (including reasonable attorneys’ fees). There have been no amounts accrued in respect of these indemnification provisions through March 28, 2014. | ||||||||
Guarantees | ||||||||
The Company has $0.5 million of guarantees in Israel as of March 28, 2014, with the majority relating to rent obligations for buildings used by its Israeli subsidiaries. | ||||||||
Legal proceedings | ||||||||
From time to time, the Company is involved in lawsuits as well as subject to various legal proceedings, claims, threats of litigation, and investigations in the ordinary course of business, including claims of alleged infringement of third-party patents and other intellectual property rights, commercial, employment, and other matters. The Company assesses potential liabilities in connection with each lawsuit and threatened lawsuits and accrues an estimated loss for these loss contingencies if both of the following conditions are met: information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of loss can be reasonably estimated. While certain matters to which the Company is a party specify the damages claimed, such claims may not represent reasonably possible losses. Given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated. | ||||||||
In October 2011, Avid Technology, Inc. (“Avid”) filed a complaint in the United States District Court for the District of Delaware alleging that Harmonic’s Media Grid product infringes two patents held by Avid. A jury trial on this complaint commenced on January 23, 2014 and, on February 4, 2014, the jury returned a unanimous verdict in favor of Harmonic, rejecting Avid's infringement allegations in their entirety. Avid has indicated it intends to appeal the verdict. | ||||||||
In June 2012, Avid served a subsequent complaint in the United States District Court for the District of Delaware alleging that Harmonic’s Spectrum product infringes one patent held by Avid. The complaint seeks injunctive relief and unspecified damages. In September 2013, the U.S. Patent Trial and Appeal Board ("PTAB") authorized an inter partes review to be instituted as to claims of the patent asserted in this second complaint. A hearing before the PTAB has been scheduled for May 2014. | ||||||||
An unfavorable outcome on any litigation matter could require that Harmonic pay substantial damages, or, in connection with any intellectual property infringement claims, could require that the Company pay ongoing royalty payments or could prevent the Company from selling certain of its products. As a result, a settlement of, or an unfavorable outcome on, any of the matters referenced above or other litigation matters could have a material adverse effect on Harmonic’s business, operating results, financial position and cash flows. |

Common Stock Repurchases | ||||||||
On April 24, 2012, our Board of Directors (the "Board") approved a stock repurchase program that provided for the repurchase of up to $25 million of our outstanding common stock. During 2013, the Board approved $195 million of increases to the program, increasing the aggregate authorized amount of the program to $220 million. On February 6, 2013, the Board approved a modification to the program that permits the Company to also repurchase its common stock pursuant to a plan that meets the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934. The repurchase program is scheduled to expire in December 2014. | ||||||||
As of March 28, 2014, we had purchased 27.7 million shares of common stock under this program at a weighted average price of $6.03 per share for an aggregate purchase price of $167.3 million, excluding fees. The remaining authorized amount for stock repurchases under this program was $52.7 million as of March 28, 2014.

Discontinued Operations | ||||||
In the first quarter of fiscal 2013, the Company completed the sale of its cable access hybrid-fiber coaxial ("HFC") business to Aurora Networks (“Aurora”). The results of operations associated with the cable access HFC business were presented as discontinued operations in its unaudited condensed consolidated financial statements as described in Note 3, "Discontinued Operations". There were no operating activities associated with the cable access HFC business after December 31, 2013. Unless noted otherwise, all discussions herein with respect to the Company’s unaudited condensed consolidated financial statements relate to the Company’s continuing operations. | ||||||

Use of Estimates | ||||||
The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. | ||||||

Recent Accounting Pronouncements | ' | |||||
RECENT ACCOUNTING PRONOUNCEMENTS | ||||||
In March 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon De-recognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity”. The ASU addresses accounting for a cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The new guidance became effective for the Company beginning in the first quarter of fiscal 2014 and it did not have a material impact on the Company’s Consolidated Financial Statements. | ||||||
In July 2013, the FASB issued ASU 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. Under certain circumstances, unrecognized tax benefits should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The new guidance became effective for the Company beginning in the first quarter of fiscal 2014 and it did not have a material impact on the Company’s Consolidated Financial Statements. | ||||||
On April 10, 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. This guidance raises the threshold for a disposal to qualify as a discontinued operation and requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. The guidance is effective for the Company beginning in the first quarter of fiscal 2015. The Company does not expect the adoption of ASU 2014-08 will have a material impact on its financial position, results of operations or cash flows. | ||||||
Impairment of Investments | ' | |||||
Impairment of Investments | ||||||
The Company monitors its investment portfolio for impairment on a periodic basis. In the event that the carrying value of an investment exceeds its fair value and the decline in value is determined to be other-than-temporary, an impairment charge is recorded and a new cost basis for the investment is established. A decline of fair value below amortized costs of debt securities is considered other-than-temporary if the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis. At the present time, the Company does not intend to sell its investments that have unrealized losses in accumulated other comprehensive loss. In addition, the Company does not believe that it is more likely than not that it will be required to sell its investments that have unrealized losses in accumulated other comprehensive loss before the Company recovers the principal amounts invested. The Company believes that the unrealized losses are temporary and do not require an other-than-temporary impairment, based on its evaluation of available evidence as of March 28, 2014. | ||||||
As of March 28, 2014, there were no individual available-for-sale securities in a material unrealized loss position and the amount of unrealized losses on the total investment balance was insignificant. | ||||||
Fair Value of Financial Instruments | ' | |||||
The applicable accounting guidance establishes a framework for measuring fair value and requires disclosure about the fair value measurements of assets and liabilities. This guidance requires the Company to classify and disclose assets and liabilities measured at fair value on a recurring basis, as well as fair value measurements of assets and liabilities measured on a nonrecurring basis in periods subsequent to initial measurement, in a three-tier fair value hierarchy as described below. | ||||||
The guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability, in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. | ||||||
Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The guidance describes three levels of inputs that may be used to measure fair value: | ||||||
• | Level 1 — Observable inputs that reflect quoted prices for identical assets or liabilities in active markets. | |||||
• | Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company primarily uses broker quotes for valuation of its short-term investments. The forward exchange contracts are classified as Level 2 because they are valued using quoted market prices and other observable data for similar instruments in an active market. | |||||
• | Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | |||||
The Company uses the market approach to measure fair value for its financial assets and liabilities. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. During the three months ended March 28, 2014, there were no nonrecurring fair value measurements of assets and liabilities subsequent to initial recognition. | ||||||
Share-based Compensation Expense | ' | |||||
Stock Options | ||||||
The Company estimated the fair value of all employee stock options using a Black-Scholes valuation model with the following weighted average assumptions: | ||||||
Three months ended | ||||||
March 28, | March 29, | |||||
2014 | 2013 | |||||
Expected term (years) | 4.7 | 4.7 | ||||
Volatility | 40 | % | 52 | % | ||
Risk-free interest rate | 1.7 | % | 0.8 | % | ||
Expected dividends | 0 | % | 0 | % | ||
The expected term represents the weighted-average period that the stock options are expected to remain outstanding. The computation of the expected term was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. The Company uses its historical volatility for a period equivalent to the expected term of the options to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model. | ||||||
The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. | ||||||
The weighted-average fair value per share of options granted was $2.35 and $2.50 for the three months ended March 28, 2014 and March 29, 2013, respectively. | ||||||
The fair value of all stock options vested during the three months ended March 28, 2014 and March 29, 2013 was $1,330,000 and $1,260,000, respectively. | ||||||
The total realized tax benefit attributable to stock options exercised during the three months ended March 28, 2014, in jurisdictions where this expense is deductible for tax purposes, was $185,000. The Company did not recognize any tax benefit attributable to stock options exercised during the three months ended March 29, 2013. | ||||||
Restricted Stock Units | ||||||
The estimated fair value of all restricted stock units issued during the three months ended March 28, 2014 and March 29, 2013 was $5.4 million and $5.6 million, respectively. | ||||||
Employee Stock Purchase Plan | ||||||
The value of the stock purchase rights under the ESPP consists of: (1) the 15% discount on the purchase of the stock; (2) 85% of the fair value of the call option; and (3) 15% of the fair value of the put option. The call option and put option were valued using the Black-Scholes option pricing model. The weighted average fair value of the Company's ESPP shares at purchase dates was estimated using the following weighted average assumptions during the three months ended March 28, 2014 and March 29, 2013: | ||||||
Purchase Period Ending | ||||||
June 30, | June 30, | |||||
2014 | 2013 | |||||
Expected term (years) | 0.5 | 0.49 | ||||
Volatility | 29 | % | 32 | % | ||
Risk-free interest rate | 0.1 | % | 0.2 | % | ||
Expected dividends | 0 | % | 0 | % | ||
Estimated weighted average fair value per share at purchase date | $1.71 | $1.20 | ||||
The expected term represents the period of time from the beginning of the offering period to the purchase date. The Company uses its historical volatility for a period equivalent to the expected term of the options to estimate the expected volatility. The risk-free interest rate that the Company uses in the Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model. | ||||||
The ESPP was suspended for the second half of 2013 due to all authorized shares under the plan having been issued through the offering period ended June 30, 2013. The Company’s stockholders approved a 1,000,000 share increase in the authorized shares for the ESPP during the Company’s annual meeting on August 14, 2013, and contributions under the ESPP resumed in January 2014. As a result, the Company did not have any stock-based compensation expense in the second half of fiscal 2013 related to the ESPP. | ||||||
Unrecognized Stock-Based Compensation | ||||||
As of March 28, 2014, total unamortized stock-based compensation cost related to unvested stock options and restricted stock units was $23.9 million. This amount will be recognized as expense using the straight-line attribution method over the remaining weighted-average amortization period of 2.0 years. | ||||||
Income Tax | ' | |||||
As of March 28, 2014, the total amount of gross unrecognized tax benefits, including interest and penalties, was approximately $26.1 million, that if recognized, would affect the Company's effective tax rate. The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense. The Company had $1.7 million of gross interest and penalties accrued as of March 28, 2014. The Company will continue to review its tax positions and provide for, or reverse, unrecognized tax benefits as issues arise. As of March 28, 2014, the Company anticipates that the balance of gross unrecognized tax benefits will decrease up to approximately $10 million due to expiration of the applicable statues of limitations over the next 12 months. | ||||||
The Company assesses the realizability of its deferred tax assets on a quarterly basis. A valuation allowance may be recorded in the event it is deemed to be more-likely-than-not that the deferred tax asset cannot be realized.The Company believes, based on the quarterly assessment performed at March 28, 2014, that it is possible that a valuation allowance may be required in the future. |
