Basis of Presentation [Abstract]

Basis of Presentation

The Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q have been prepared by Cadence Design Systems, Inc., or Cadence, without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission, or the SEC. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, Cadence believes that the disclosures contained in this Quarterly Report on Form 10-Q comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. These Condensed Consolidated Financial Statements are meant to be, and should be, read in conjunction with the Consolidated Financial Statements and the Notes thereto included in Cadence’s Annual Report on Form 10-K for the fiscal year ended December 31, 2011. Certain prior period balances have been reclassified to conform to current period presentation.

The unaudited Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q reflect all adjustments (which include only normal, recurring adjustments and those items discussed in these Notes) that are, in the opinion of management, necessary to state fairly the results of operations, cash flows and financial position for the periods and dates presented. The results for such periods are not necessarily indicative of the results to be expected for the full fiscal year.

Preparation of the Condensed Consolidated Financial Statements in conformity with United States generally accepted accounting principles 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 Condensed Consolidated Financial Statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Fair Value of Financial Instruments

Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Cadence’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

• Level 1 – Quoted prices for identical instruments in active markets;

• Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

• Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

This hierarchy requires Cadence to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. Cadence recognizes transfers between levels of the hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. There were no transfers between levels of the fair value hierarchy during the three and six months ended June 30, 2012.

The carrying value of Cadence’s cash and cash equivalents held in money market funds approximates fair value and is based on level 1 inputs. The carrying value of Cadence’s receivables, interest receivable, accounts payable and accrued liabilities approximates their fair value due to the short-term nature of these instruments and is based on level 2 inputs. The carrying values of Cadence’s long-term receivables approximate their fair values and are based on level 2 inputs, including current market rates of interest. The fair values of Cadence’s 2013 Notes and 2015 Notes, which differ from their carrying values, are influenced by interest rates and Cadence’s stock price and stock price volatility and are determined by prices for the 2013 Notes and 2015 Notes observed in market trading, which are level 2 inputs. The fair values of Cadence’s 2015 Notes Hedges and 2015 Notes Embedded Conversion Derivative are determined by level 1 and level 2 inputs, including interest rates, Cadence’s stock price and stock price volatility.

Contingencies

Legal Proceedings

From time to time, Cadence is involved in various disputes and litigation that arise in the ordinary course of business. These include disputes and lawsuits related to intellectual property, indemnification obligations, mergers and acquisitions, licensing, contracts, distribution arrangements and employee relations matters. At least quarterly, Cadence reviews the status of each significant matter and assesses its potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount or the range of loss can be estimated, Cadence accrues a liability for the estimated loss. Legal proceedings are subject to uncertainties, and the outcomes are difficult to predict. Because of such uncertainties, accruals are based on Cadence’s judgments using the best information available at the time. As additional information becomes available, Cadence reassesses the potential liability related to pending claims and litigation matters and may revise estimates.

Non-Marketable Investments

Non-Marketable Investments

Cadence’s non-marketable investments generally consist of voting preferred stock or convertible debt of privately-held companies and are included in other assets on Cadence’s Condensed Consolidated Balance Sheets. If Cadence determines that it has the ability to exercise significant influence over the issuer, which may include considering whether the investments are in-substance common stock, the investment is accounted for using the equity method.

Marketable Securities Available For Sale Securities Policy

Cadence’s short-term investments include marketable debt securities with original maturities greater than three months on the date of purchase and marketable equity securities. Cadence considers its entire portfolio of marketable debt and equity securities to be available for sale and available to fund current operations. Available-for-sale debt securities are carried at fair value, with the unrealized gains and losses presented net of tax as a separate component of other comprehensive income. Unrealized and realized gains and losses are determined using the specific identification method.

Cadence recognizes gains on its available-for-sale securities when they are realized. Cadence recognizes losses on its available-for-sale securities when they are realized or when Cadence has determined that an other-than-temporary decline in fair value has occurred. Cadence reviews its available-for-sale securities each quarter to determine if an other-than-temporary decline in fair value has occurred. For an available-for-sale debt security, an other-than-temporary decline in fair value has occurred when the security’s fair value is less than its amortized cost basis and Cadence intends to sell the security, or it is more likely than not that Cadence will be required to sell the security, before recovery of its amortized cost basis. Cadence records realized gains, realized losses and other-than-temporary impairments as part of other income, net in the Condensed Consolidated Income Statements.
