Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring items, necessary for a fair presentation of the financial statements for interim periods in accordance with accounting principles generally accepted in the United States (US GAAP). The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and the notes thereto for the fiscal year ended December 28, 2013 included in the Company’s Annual Report on Form 10-K filed on February 19, 2014 with the Securities and Exchange Commission (“SEC”). The Company’s accounting policies are described in the “Notes to consolidated financial statements” in our Form 10-K and updated as necessary, in this Form 10-Q. The year-end condensed consolidated balance sheet data presented for comparative purposes was derived from audited financial statements, but does not include all disclosures required by US GAAP. The results of operations for the three and six months ended June 28, 2014 are not necessarily indicative of the operating results for the full year or for any other subsequent interim period.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation.

Accounting Periods

The Company uses a 52- or 53-week fiscal year ending on the last Saturday in December. Fiscal year 2013 was a 52-week year ending on December 28, 2013. The Company’s second quarter for fiscal year 2014 and 2013 were 26-week periods ending on June 28, 2014 and June 29, 2013, respectively.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements as well as the reported amounts of net revenue and expense during the reporting period. The Company regularly evaluates estimates and assumptions related to areas such as revenue recognition, allowances for doubtful accounts, warranty obligations, inventory valuation, stock-based compensation expense, deferred income tax valuation allowances, litigation and other loss contingencies. These estimates and assumptions are based on current facts, historical experience and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs and expenses that are not readily apparent from other sources. Actual results may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and actual results, the Company’s future results of operations will be affected.

Concentration of Credit Risk

Financial assets and liabilities, which potentially subject the Company to concentrations of credit risk, consist primarily of cash equivalents, marketable securities, and accounts receivable. The Company limits its exposure to credit loss by placing its cash in high credit quality financial investments. At times, such deposits may be in excess of insured limits. The Company has not experienced any significant losses on its investments.

Customers that exceed 10% of total net revenue were as follows:



	Three Months Ended				Six Months Ended
	June 28, 2014		June 29, 2013		June 28, 2014		June 29, 2013
Macnica	48	%	71	%	41	%	68	%
Murata	21	%	*		24	%	*
Richardson	12	%	10	%	14	%	13	%

* Did not exceed 10% of total revenues for the respective period.

A significant portion of the Company's net revenue is derived from a limited number of distributors, in particular, Macnica and Richardson. Historically, the majority of sales through the Company's distributor, Macnica, were to module manufacturer Murata. The decrease in Macnica sales during the three and six months ended June 28, 2014 was due to the Company beginning to sell directly to Murata.

Fair Value of Financial Instruments

The Company applies fair value accounting for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company’s financial instruments consist principally of cash and cash equivalents and marketable securities. The fair value of a financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) defined as follows:

Level 1: Inputs are based on quoted market prices for identical assets or liabilities in active markets at the measurement date.

Level 2: Inputs include quoted prices for similar assets or liabilities in active markets and/or quoted prices for identical or similar assets or liabilities in markets that are not active near the measurement date.

Level 3: Inputs include management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation.

The fair value of the Company’s cash equivalents was determined based on “Level 1” inputs. The fair value of marketable securities was determined based on “Level 2” inputs. The fair value of the Company’s “Level 2” instruments were valued based on the market approach technique which uses quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The Company does not have any marketable securities in the “Level 3” category. The Company believes that the recorded values of all of the other financial assets and liabilities approximate their current fair values because of maturity and respective duration of these assets and liabilities.

Warranty Accrual

The Company generally provides a product warranty for a period of one year; however, it may be longer for certain customers. Accordingly, the Company establishes provisions for estimated product warranty costs at the time net revenue is recognized based upon historical activity and, additionally, for any known product warranty issues. Warranty provisions are recorded as a cost of net revenue. The determination of such provisions requires the Company to make estimates of product return rates and expected costs to replace or rework the products under warranty. When the actual product failure rates, cost of replacements and rework costs differ from the original estimates, revisions to the estimated warranty accrual are made. Actual claims are charged against the warranty reserve.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. ASU 2014-09 will be effective for the Company beginning in its first quarter of 2017. Early adoption is not permitted. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently evaluating the impact of adopting the new revenue standard on its consolidated financial statements and whether it will be adopted retrospectively to each period presented or with the cumulative effect as of the date of adoption.
