The Company and Summary of Significant Accounting Policies  
Basis of Presentation

Basis of Presentation

 

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year is the calendar year.

 
Use of Estimates

Use of Estimates

 

The preparation of financial statements in accordance with accounting principles generally accepted in the United States 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 reported amounts of revenues and expenses recognized during the reported period. Actual results could differ from those estimates.

 
Cash Equivalents and Investments

Cash Equivalents and Investments

 

The Company has invested its excess cash in money market accounts, certificates of deposit, commercial paper, corporate debt, government agency and municipal debt securities and considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company’s available-for-sale short-term and long-term investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income (loss). Realized gains and losses and declines in the value judged to be other than temporary are included in the other income and expense, net line item in the condensed consolidated statements of operations and comprehensive loss. The cost of securities sold is based on the specific identification method.

 
Fair Value Measurements

Fair Value Measurements

 

The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:

 

Level 1—Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date.

 

Level 2—Pricing is provided by third party sources of market information obtained through the Company’s investment advisors rather than models. The Company does not adjust for or apply any additional assumptions or estimates to the pricing information it receives from advisors. The Company’s Level 2 securities include cash equivalents and available-for-sale securities, which consisted primarily of certificates of deposit, commercial paper, corporate debt, and government agency and municipal debt securities from issuers with high quality credit ratings. The Company’s investment advisors obtain pricing data from independent sources, such as Standard & Poor’s, Bloomberg and Interactive Data Corporation, and rely on comparable pricing of other securities because the Level 2 securities are not actively traded and have fewer observable transactions. The Company considers this the most reliable information available for the valuation of the securities.

 

Level 3—Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 investments and other financial instruments involves the most management judgment and subjectivity.

 
Allowance for Doubtful Accounts

Allowance for Doubtful Accounts

 

The Company establishes an allowance for doubtful accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer credit evaluations within the context of the industry in which it operates. A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not require collateral from its customers. The Company grants credit only to customers deemed creditworthy in the judgment of management. The Company maintains an allowance for doubtful accounts receivable based upon the expected collectibility of all accounts receivable. There was no allowance for doubtful accounts receivable at June 30, 2012 or December 31, 2011.

 
Inventory

Inventory

 

The Company values its inventories at the lower of cost, which approximates actual cost on a first-in, first-out basis, or market value.  The Company records inventory reserves for estimated obsolescence or unmarketable inventories based upon assumptions about future demand and market conditions.  Once a reserve is established, it is maintained until the product to which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional adjustment to inventory valuation may be required.  As of June 30, 2012, inventory was not significant and has been included in the prepaid expenses and other current assets line item of the condensed consolidated balance sheets.

 
Revenue Recognition

Revenue Recognition

 

General

 

The Company generates revenue from the licensing of its IP and sales of IC products. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery or performance has occurred, the sales price is fixed or determinable, and collectibility is reasonably assured. Evidence of an arrangement generally consists of signed agreements or customer purchase orders.

 

Licensing

 

Licensing revenue consists of fees earned from license agreements, development services and support and maintenance. For stand-alone license agreements or license deliverables in multi-deliverable arrangements that do not require significant development, modification or customization, revenues are recognized when all revenue recognition criteria have been met. Delivery of the licensed technology is typically the final revenue recognition criterion met, at which time revenue is recognized. If any of the criteria are not met, revenue recognition is deferred until such time as all criteria have been met.

 

When sales arrangements contain multiple deliverables (e.g., license and services), the Company reviews each deliverable to determine the separate units of accounting that exist within the agreement. If more than one unit of accounting exists, the consideration payable to the Company under the agreement is allocated to each unit of accounting using the relative fair value method.

Revenue is recognized for each unit of accounting when the revenue recognition criteria have been met for that unit of accounting. The Company allocates revenue among the deliverables using the relative selling price method. Revenue allocated to each element is recognized when the basic revenue recognition criteria is met for each element. Under GAAP, the Company is required to apply a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of fair value (VSOE), (ii) third-party evidence of selling price (TPE) and (iii) best estimate of the selling price (ESP). In general, the Company is unable to establish VSOE or TPE for license fees and development services.  Therefore revenue is allocated to these elements based on the Company’s ESP, which the Company determines after considering multiple factors such as management approved pricing guidelines, geographic differences, market conditions, competitor pricing strategies, internal costs and gross margin objectives. These factors may vary over time depending upon the unique facts and circumstances related to each deliverable. If the facts and circumstances underlying the factors considered change or should future facts and circumstances lead the Company to consider additional factors, the Company’s ESP for license fee and development services could change.

 

For license agreements involving deliverables that do require significant production, modification or customization, and where the Company has significant experience in meeting the design specifications in the contract and the direct labor hours related to services under the contract can be reasonably estimated, the Company recognizes revenue over the period in which the contract services are performed. For these arrangements, the Company recognizes revenue using the percentage of completion method. Under this method, revenue recognized in any period depends on the Company’s progress toward completion of projects in progress. Significant management judgment and discretion are used to estimate total direct labor hours. These judgmental elements include determining that the Company has the experience to meet the design specifications and estimate the total direct labor hours to perform the contract services, based on experience in developing prior licensees’ designs. The direct labor hours for the development of the licensee’s design are estimated at the beginning of the contract. As the direct labor hours are incurred, they are used as a measure of progress towards completion. During the contract performance period, the Company reviews estimates of direct labor hours to complete the contracts and will revise its estimates of revenue and gross profit under the contract if it revises the estimations of the direct labor hours to complete. The Company’s policy is to reflect any revision in the contract gross profit estimate in reported income or loss in the period in which the facts giving rise to the revision become known. Under the percentage of completion method, provisions for estimated losses on uncompleted contracts are recorded in the period in which such losses are determined to be likely. If the amount of revenue recognized under the percentage of completion accounting method exceeds the amount of billings to a customer, the excess amount is recorded as an unbilled contracts receivable. Unbilled contracts receivable as of June 30, 2012 and December 31, 2011 are not considered significant and have been included in the prepaid expenses and other current assets line item of the condensed consolidated balance sheets.

 

The Company provides support and maintenance under many of its license agreements. Under these arrangements, the Company provides unspecified upgrades, design rule changes and technical support. No other upgrades, products or other post-contract support are provided. Support and maintenance revenue is recognized at its fair value established by VSOE, ratably over the period during which the obligation exists, typically 12 months. These arrangements are generally renewable annually by the customer.

 

Under limited circumstances, the Company also recognizes prepaid pre-production royalties as license revenues. These are lump sum payments made when the Company enters into licensing agreements that cover future shipments of a product that is not commercially available from the licensee. The Company characterizes such payments as license revenues because they are paid as part of the initial license fee and not with respect to products being produced by the licensee. These payments are non-cancelable and non-refundable.

 

Royalty

 

The Company’s licensing contracts typically also provide for royalties based on licensees’ use of the Company’s memory technology in their currently shipping commercial products. The Company recognizes royalties in the quarter in which it receives the licensee’s report. Under limited circumstances, the Company may also recognize prepaid post-production royalties as revenue upon execution of the contract, which are paid in a lump sum after the licensee commences production of the royalty-bearing product and applied against future unit shipments regardless of the actual level of shipments by the licensee. The criteria for revenue recognition of prepaid royalties are that a formal agreement with the licensee is executed, no deliverables, development or support services related to prepaid royalties are required, the fees are non-refundable and not contingent upon future product shipments by the licensee, and the fees are payable by the licensee in a time period consistent with the Company’s normal billing terms. If any of these criteria are not met, the Company defers revenue recognition until such time as all criteria have been met.

 

IC products

 

The Company sells products both directly to customers, as well as through distributors.  Revenue from sales directly to customers is generally recognized at the time of shipment. The Company records an estimated allowance, at the time of shipment, for future returns and other charges against revenue consistent with the terms of sale.  IC product revenue and costs relating to sales made through distributors with rights of return and stock rotation are deferred until the distributors sell the product to end customers due to the Company’s inability to estimate future returns and credits to be issued.  At the time of shipment to distributors, an accounts receivable for the selling price is recorded, as there is a legally enforceable right to receive payment, and inventory is relieved, as legal title to the inventory is transferred upon shipment.  Revenues are recognized upon receiving notification from the distributors that products have been sold to end customers. Distributors provide information regarding products and quantity, end customer shipments and remaining inventory on hand.  The associated deferred margin is included in the deferred revenues line item in the condensed consolidated balance sheet.  The Company recorded initial IC product revenue in 2012, and a significant reserve for returns has been recorded due to the product’s early stage of development and testing. IC product revenue was not significant for the three and six months ended June 30, 2012, and has been included in the licensing and other revenue line item in the condensed consolidated statements of operations and comprehensive loss.

 
Cost of Revenue

Cost of Revenue

 

Cost of licensing and other revenue consists primarily of engineering personnel and overhead allocation costs directly related to development services specified in licensing agreements and direct and indirect costs of IC product sales. Development services typically include customization of the Company’s technologies for the licensee’s particular IC design and may include engineering support to assist in the commencement of production of a licensee’s products.

 
Goodwill

Goodwill

 

The Company reviews goodwill for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The Company first assesses qualitative factors to determine whether it is more-likely-than-not that the fair value of the reporting unit is less than the carrying amount as a basis for determining whether it is necessary to perform the two-step impairment test. If the qualitative assessment warrants further analysis, the Company compares the fair value of the reporting unit to its carrying value. The fair value of the reporting unit is determined using the market approach. If the fair value of the reporting unit exceeds the carrying value of net assets of the reporting unit, goodwill is not impaired, and the Company is not required to perform further testing. If the carrying value of the net assets of the reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step in order to determine the implied fair value of the reporting unit’s goodwill and compare it to the carrying value of the reporting unit’s goodwill. If the carrying value of the reporting unit’s goodwill exceeds its implied fair value, then the Company must record an impairment charge equal to the difference. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. The Company performed the annual impairment test in September 2011, and the test did not indicate impairment of goodwill, as the fair value exceeded the carrying value of the reporting unit by approximately 61%. As the Company used the market approach to assess impairment, the price of its common stock is an important component of the fair value calculation. If the Company’s stock price continues to experience significant price and volume fluctuations, this will impact the fair value of the reporting unit, which can lead to potential impairment in future periods. As of June 30, 2012, the Company had not identified any factors to indicate there was an impairment of our goodwill and determined that no additional impairment analysis was required.

 
Intangible Assets

Intangible Assets

 

Intangible assets acquired in business combinations, referred to as purchased intangible assets, are accounted for based on the fair value of assets purchased and are amortized over the period in which economic benefit is estimated to be received. Identifiable intangible assets relating to business combinations and the patent license were as follows (dollar amounts in thousands):

The related amortization expense was $0.6 million and $0.7 million for the three months ended June 30, 2012 and 2011, respectively. The related amortization expense was $1.2 million and $1.3 million for the six months ended June 30, 2012 and 2011, respectively. Amortization expense has been included in research and development expense in the condensed consolidated statements of operations and comprehensive loss.  The estimated aggregate amortization expense to be recognized in future years is approximately $0.5 million for the remainder of 2012, $1.0 million for 2013, $1.0 million for 2014, $0.3 million for 2015 and $0.1 million annually for 2016 through 2018.

 
Per Share Amounts

Per Share Amounts

 

Basic net loss per share is computed by dividing net loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share gives effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of incremental shares of common stock issuable upon the exercise of stock options, vesting of stock awards and purchases under the employee stock purchase plan. As of June 30, 2012 and 2011, stock awards to purchase approximately 10,931,000 and 10,174,000 shares, respectively, were excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive.
