Basis of Presentation and Significant Accounting Policies (Policies)

6 Months Ended

Jun. 27, 2014

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 six months ended June 27, 2014.

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.

On May 28, 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers", requiring an entity to recognize the amount of revenue that reflects the consideration to which it expects to be entitled for the transfer of promised goods or services to customers. The updated standard will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard becomes effective for the Company in the first quarter of fiscal 2017. We have not yet selected a transition method and we are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures.

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.

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 June 27, 2014.

As of June 27, 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.

Derivatives and Hedging Activities

The Company enters into foreign currency forward contracts to minimize the short-term impact of foreign currency exchange rate fluctuations on cash and certain trade and inter-company receivables and payables, primarily denominated in Euro, British pound, Japanese yen and Israeli shekel. These contracts reduce the exposure to fluctuations in foreign currency exchange rate movements as the gains and losses associated with foreign currency balances are generally offset with the gains and losses on the forward contracts. These contracts are not designated as hedges that are eligible for hedge accounting treatment and are marked to market through earnings every period and generally range from one to three months in original maturity. We do not enter into foreign currency forward contacts for trading purposes.

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 six months ended June 27, 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				Six months ended
	June 27, 2014		June 28, 2013		June 27, 2014		June 28, 2013
Expected term (years)	4.70		4.70		4.70		4.70
Volatility	39	%	49	%	40	%	51	%
Risk-free interest rate	1.7	%	1.1	%	1.7	%	0.8	%
Expected dividends	0.0	%	0.0	%	0.0	%	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 $2.70 and $2.60 for the three months ended June 27, 2014 and June 28, 2013, respectively. The weighted-average fair value per share of options granted was $2.35 and $2.50 for the six months ended June 27, 2014 and June 28, 2013, respectively.

The fair value of all stock options vested during the three months ended June 27, 2014 and June 28, 2013 were both at $0.7 million. The fair value of all stock options vested during the six months ended June 27, 2014 and June 28, 2013 were both at $2.0 million.

The total realized tax benefit attributable to stock options exercised during the three and six months ended June 27, 2014, in jurisdictions where this expense is deductible for tax purposes, was $119,000 and $304,000, respectively. The Company did not recognize any tax benefit attributable to stock options exercised during the six months ended June 28, 2013.

Restricted Stock Units

The aggregate fair value of all restricted stock units issued during the three months ended June 27, 2014 and June 28, 2013 was $2.0 million and $1.8 million respectively. The estimated fair value of all restricted stock units issued during the six months ended June 27, 2014 and June 28, 2013 were both at $7.4 million.

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 six months ended June 27, 2014 and June 28, 2013:



	Purchase Period Ending
	June 30, 2014		June 30, 2013
Expected term (years)	0.50		0.49
Volatility	28	%	30	%
Risk-free interest rate	0.1	%	0.2	%
Expected dividends	0.0	%	0.0	%
Estimated weighted average fair value per share at purchase date	$1.70		$1.23

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 June 27, 2014, total unamortized stock-based compensation cost related to unvested stock options and restricted stock units was $20.6 million. This amount will be recognized as expense using the straight-line attribution method over the remaining weighted-average vesting period of 1.8 years.

Income Tax

As of June 27, 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 $1.8 million of gross interest and penalties accrued as of June 27, 2014. The Company will continue to review its tax positions and provide for, or reverse, unrecognized tax benefits as issues arise. As of June 27, 2014, the Company anticipates that the balance of gross unrecognized tax benefits will decrease up to approximately $8.3 million due to expiration of the applicable statues of limitations over the next twelve months.

The Company's effective rate for the six months ended June 28, 2013 was slightly lower than the U.S. federal statutory rate of 35% primarily attributable to the net of various discrete items, non-deductible amortization on foreign intangibles, the differential in foreign tax rates, federal research and development tax credit, and non-deductible stock-based compensation expense. The discrete items included primarily the increase in the valuation allowance on California research and development tax credit and accrued interest on uncertain tax positions, offset partially by the benefit associated with the reinstatement of the prior year's federal research and development tax credit, and the benefit associated with the reversal of previously recorded foreign income taxes due to the expiration of the statute of limitation in the foreign jurisdictions.

Warranties and Indemnification

The Company accrues for estimated warranty costs at the time of product shipment. Management periodically reviews the estimated fair value of its warranty liability and records adjustments based on the terms of warranties provided to customers, historical and anticipated warranty claims experience, and estimates of the timing and cost of warranty claims.

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).
