Description of Business

NOTE 1. DESCRIPTION OF BUSINESS

Intuitive designs, manufactures and markets da Vinci Surgical Systems and related instruments and accessories, which taken together, are advanced surgical systems that the Company believes represent a new generation of surgery. The Company believes that this new generation of surgery, which the Company calls da Vinci surgery, combines the benefits of minimally invasive surgery (“MIS”) for patients with the ease of use, precision and dexterity of open surgery. A da Vinci Surgical System consists of a surgeon’s console, a patient-side cart and a high performance vision system. The da Vinci Surgical System translates a surgeon’s natural hand movements, which are performed on instrument controls at a console, into corresponding micro-movements of instruments positioned inside the patient through small incisions, or ports. The da Vinci Surgical System is designed to provide its operating surgeons with intuitive control, range of motion, fine tissue manipulation capability and 3-D, High-Definition (“HD”) vision while simultaneously allowing them to work through the small ports of MIS.

Summary of Significant Accounting Policies

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements (“financial statements”) of Intuitive Surgical, Inc. and its wholly-owned subsidiaries have been prepared on a consistent basis with the audited Consolidated Financial Statements for the fiscal year ended December 31, 2012 and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”), and, therefore, omit certain information and footnote disclosure necessary to present the statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). These financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which was filed on February 4, 2013. The results of operations for the first three months of fiscal 2013 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods.

New Accounting Standards Recently Adopted

Effective January 1, 2013 the Company adopted the accounting guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company elected to present the information in the notes to the Company’s unaudited condensed consolidated financial statements.

Effective January 1, 2013 the Company adopted the accounting standard which requires an entity to provide enhanced disclosures about certain financial instruments and derivative instruments that are offset in the statement of financial position or that are subject to enforceable master netting arrangements. The adoption did not have any impact on the Company’s unaudited condensed consolidated financial statements.

Net realized gains or losses recognized on the sale of investments during the three month periods ended March 31, 2013 and 2012, respectively, were not significant. As of March 31, 2013 and December 31, 2012, net unrealized gains (losses) of $7.3 million and $6.2 million, respectively, were included in accumulated other comprehensive income in the accompanying unaudited Condensed Consolidated Balance Sheets.

There have been no transfers between Level 1 and Level 2 measurements during the three months ended March 31, 2013, and there were no changes in the Company’s valuation technique. Level 3 assets consist of municipal bonds with auction rate securities (“ARS”) whose underlying assets are student loans which are generally backed by the federal government. Since the auctions for these securities have continued to fail since February 2008, these investments are not currently trading and therefore do not have a readily determinable fair value. The Company has valued the ARS using a discounted cash flow model based on Level 3 assumptions, including estimates of, based on data available as of March 31, 2013, interest rates, timing and amount of cash flows, credit and liquidity premiums and expected holding periods of the ARS.

Foreign currency derivatives

The Company has $2.4 million of derivative assets recorded as prepaid and other current assets in the unaudited Condensed Consolidated Balance Sheets at March 31, 2013, compared to $2.7 million of derivative liabilities recorded as other accrued liabilities in the Condensed Consolidated Balance Sheets at December 31, 2012. The derivative assets and liabilities are measured using Level 2 fair value inputs.

Cash Flow Hedges

The Company enters into currency forward contracts as cash flow hedges to hedge certain forecasted revenue transactions denominated in currencies other than the U.S. dollar, primarily the European Euro (“Euro or €”) and the Korean Won (“KRW”).

As of March 31, 2013, the Company had notional amounts of €9.8 million and KRW2.2 billion of outstanding currency forward contracts entered into to hedge Euro and KRW denominated sales, compared to €20.0 million and KRW4.4 billion of outstanding currency forward contracts at December 31, 2012. The net gains (losses) reclassified to revenue related to the hedged revenue transactions for the three months ended March 31, 2013 and 2012 were not significant. Other impacts of derivative instruments designated as cash flow hedges were not significant for the three months ended March 31, 2013 and 2012.

Other Derivatives Not Designated as Hedging Instruments

Other derivatives not designated as hedging instruments consist primarily of forward contracts that the Company uses to hedge intercompany balances and other monetary assets or liabilities denominated in currencies other than the U.S. dollar, primarily the Euro, the British Pound (“GBP or £”), the Swiss Franc (“CHF”), Japanese Yen (“JPY”) and the KRW.

As of March 31, 2013, the Company had notional amounts of €21.9 million, £2.5 million, CHF1.0 million, JPY1.2 million and KRW6.6 billion of outstanding currency forward contracts that were entered into to hedge non-functional currency denominated net monetary assets and liabilities, compared to €37.6 million, £5.4 million, CHF(1.0) million and KRW4.6 billion at December 31, 2012. For the three months ended March 31, 2013 and 2012, the Company had recognized gains (losses) of approximately $1.0 million and $(0.5) million, respectively, in interest and other income (expense), net, related to derivative instruments used to hedge against balance sheet foreign currency exposures. This was offset by approximately $(1.4) million and $0.5 million of net foreign exchange gains (losses) during the three months ended March 31, 2013 and 2012, respectively, primarily related to the re-measurement of non-functional currency denominated net monetary assets and liabilities.

NOTE 5. CONTINGENCIES

On August 6, 2010, a purported class action lawsuit entitled Perlmutter v. Intuitive Surgical et al., No. CV10-3451, was filed against seven of our current and former officers and directors in the United States District Court for the Northern District of California. The lawsuit seeks unspecified damages on behalf of a putative class of persons who purchased or otherwise acquired the Company’s common stock between February 1, 2008 and January 7, 2009. The complaint alleges that the defendants violated federal securities laws by making allegedly false and misleading statements and omitting certain material facts in our filings with the Securities and Exchange Commission. On February 15, 2011, the Police Retirement System of St. Louis was appointed Lead plaintiff in the case pursuant to the Private Securities Litigation Reform Act of 1995. An amended complaint was filed on April 15, 2011, making allegations substantially similar to the allegations described above. On May 23, 2011, the Company filed a motion to dismiss the amended complaint. On August 10, 2011 that motion was granted and the action was dismissed; the plaintiffs were given 30 days to file an amended complaint. On September 12, 2011, plaintiffs filed their amended complaint. The allegations contained therein are substantially similar to the allegations in the prior complaint. The Company filed a motion to dismiss the amended complaint. A hearing occurred on February 16, 2012, and on May 22, 2012 our motion was granted. The complaint was dismissed with prejudice, and a final judgment was entered in our favor on June 1, 2012. On June 20, 2012, plaintiffs filed a notice of appeal with the United States Court of Appeals for the Ninth Circuit. The appeal is styled Police Retirement System of St. Louis v. Intuitive Surgical, Inc. et al., No. 12-16430. Plaintiffs filed their opening brief on September 28, 2012. The Company filed an answering brief on November 13, 2012, and plaintiffs filed a reply brief on December 17, 2012. No oral argument date has been set, and the appeal remains pending.

On August 19, 2010, an alleged stockholder caused a purported stockholder’s derivative lawsuit entitled Himmel v. Smith et al., No. 1-10-CV-180416, to be filed in the Superior Court of California for the County of Santa Clara naming us as a nominal defendant, and naming 14 of the Company’s current and former officers and directors as defendants. The lawsuit seeks to recover, for the Company’s benefit, unspecified damages purportedly sustained by us in connection with allegedly misleading statements and/or omissions made in connection with the Company’s financial reporting for the period between February 1, 2008 and January 7, 2009. It also seeks a series of changes to the Company’s corporate governance policies and an award of attorneys’ fees. On September 15, 2010, another purported stockholder filed an essentially identical lawsuit entitled Applebaum v. Guthart et al., No. 1-10-CV-182645, in the same court against 15 of the Company’s current and former officers and directors. On October 5, 2010 the court ordered that the two cases be consolidated for all purposes. By agreement with the plaintiffs, all activity in the case has been stayed pending the results of the appeal in the purported shareholder class action lawsuit discussed above.

The Company is currently a defendant in approximately 26 individual product liability lawsuits filed in various state and federal courts by plaintiffs who allege that they underwent surgical procedures that utilized the da Vinci Surgical System and sustained a variety of personal injuries and, in some cases, death as a result of such surgery. The cases raise a variety of allegations including, to varying degrees, that their injuries resulted from purported defects in the da Vinci Surgical System and/or failure on the part of the Company to provide adequate training resources to the healthcare professionals who performed plaintiffs’ surgeries. The cases further allege that the Company failed to adequately disclose and/or misrepresented the potential risks and/or benefits of the da Vinci Surgical System. Plaintiffs also assert a variety of causes of action, including for example, strict liability based on purported design defects, negligence, fraud, breach of express and implied warranties, unjust enrichment, and loss of consortium. Plaintiffs seek recovery for alleged personal injuries and, in many cases, punitive damages. Except for the case described below, these cases generally are in the early stages of pretrial activity.

On December 17, 2009, a product liability action entitled Josette Taylor, as Personal Representative of the Estate of Fred E. Taylor, deceased; and on behalf of the Estate of Fred E. Taylor; and Josette Taylor v. Intuitive Surgical, Inc., No. 09-2-03136-5, was filed in Washington State Superior Court for Kitsap County against the Company and the healthcare providers and hospital involved in decedent’s surgery. In Taylor, plaintiffs assert wrongful death and product liability claims against the Company, generally alleging that the decedent died four years after surgery as a result of injuries purportedly suffered during the surgery, which was conducted with the use of the da Vinci Surgical System. The plaintiffs in Taylor assert that such injuries were caused, in whole or in part, by the Company’s purported failure to properly train, warn, and instruct the surgeon. The lawsuit seeks unspecified damages for past medical expenses, pain and suffering, loss of consortium as well as punitive damages. A trial commenced in the action on April 15, 2013.

Plaintiffs’ attorneys are engaged in growing and well-funded national advertising campaigns soliciting clients who have undergone da Vinci surgery and claim to have suffered an injury. The Company has seen a substantial increase in these claims, however it has only received detailed information regarding a small number of them. In an effort to provide an orderly process for evaluating claims before they result in costly litigation, we have entered into tolling agreements with certain plaintiff’s counsel acting on behalf of such claimants. The tolling agreements provide that the statute of limitations for each individual will be tolled for a period of three to six months in exchange for the individual’s agreement that, if he or she ultimately files a lawsuit, it will be filed in certain agreed upon venues. The tolling agreements provide the parties and their legal counsel with additional time to evaluate the claims, to explore whether the claims have merit and whether they can be resolved without litigation. The Company does not currently know how many of such individuals will ultimately file lawsuits, nor is it able at this time to estimate the financial implications of their claims or predict the final disposition of such claims. The Company intends to vigorously defend lawsuits that are ultimately filed.

Due to the uncertainty surrounding the litigation process, the Company is unable to reasonably estimate the ultimate outcome of the above cases at this time, and therefore no amounts have been accrued related to the outcome of the cases above. Based on currently available information, the Company believes that it has meritorious defenses to the above actions and that the resolution of these cases is not likely to have a material adverse effect on the Company’s business, financial position or future results of operations.

The Company is also a party to various other legal actions that have arisen in the ordinary course of its business. The Company does not believe that any of these other legal actions will have a material adverse impact on its business, financial position or results of operations.

Income Taxes

Income Taxes

NOTE 8. INCOME TAXES

Income tax expense for the three months ended March 31, 2013 was $66.6 million, or 26.1% of pre-tax income, compared with $53.6 million, or 27.2% of pre-tax income for the three months ended March 31, 2012. The Company’s effective tax rates for these periods differ from the United States (“U.S.”) federal statutory rate of 35% due primarily to the effect of income earned by certain of the Company’s overseas entities being taxed at rates lower than the federal statutory rate, partially offset by state income taxes and non-deductible stock option expenses. The income tax provision for the three months ended March 31, 2013 also reflected a discrete net benefit of $7.5 million, or 2.9% of pre-tax income, related to 2012 federal research and development (“R&D”) credit which was retroactively reinstated in the three months ended March 31, 2013. No federal R&D credit benefit was recorded in the income tax provision for the three months ended March 31, 2012. The income tax provision for the three months ended March 31, 2012 included a discrete recognition of $8.5 million, or 4.3% of pre-tax income, related to certain previously unrecognized tax benefits reflecting new Internal Revenue Service (“IRS”) guidance issued in the three months ended March 31, 2012. The Company intends to indefinitely reinvest outside the U.S. all of its undistributed foreign earnings that were not previously subject to U.S. tax.

As of March 31, 2013, the Company had total gross unrecognized tax benefits of approximately $96.6 million compared with approximately $88.0 million as of December 31, 2012, representing an increase of approximately $8.6 million for the three months ended March 31, 2013. Of the total gross unrecognized tax benefits, $92.3 million and $83.8 million as of March 31, 2013 and December 31, 2012, respectively, if recognized, would reduce the effective tax rate in the period of recognition. Gross interest related to unrecognized tax benefit accrued was approximately $3.8 million and $3.2 million, respectively, as of March 31, 2013 and December 31, 2012, representing an increase of $0.6 million.

The Company files federal, state and foreign income tax returns in many jurisdictions in the United States and abroad. Generally, years before 2009 are closed for most significant jurisdictions except for California, for which all years since inception remain open due to utilization of net operating losses and R&D credits generated in prior years. Certain of the Company’s unrecognized tax benefits could reverse based on the normal expiration of various statutes of limitations, which could affect the Company’s effective tax rate in the period in which they reverse.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

NOTE 9. NET INCOME PER SHARE

The following table presents the computation of basic and diluted net income per share for the three months ended March 31, 2013 and 2012 (in millions, except per share amounts):


	Three Months Ended March 31,
	2013		2012
Numerator:
Net income	$	188.9	$	143.5

Denominator:
Weighted-average shares outstanding used in basic calculation		40.3		39.5
Add: Dilutive potential shares		1.1		1.5

Weighted-average shares used in computing diluted net income per share		41.4		41.0

Basic net income per share	$	4.69	$	3.63

Diluted net income per share	$	4.56	$	3.50

Employee stock options to purchase approximately 1.7 million and 0.4 million weighted shares for the three months ended March 31, 2013 and 2012, respectively, were outstanding, but were not included in the computation of diluted net income per share because the effect of including such shares would have been antidilutive.

Basis of Presentation	*Basis of Presentation* In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements (“financial statements”) of Intuitive Surgical, Inc. and its wholly-owned subsidiaries have been prepared on a consistent basis with the audited Consolidated Financial Statements for the fiscal year ended December 31, 2012 and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”), and, therefore, omit certain information and footnote disclosure necessary to present the statements in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). These financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which was filed on February 4, 2013. The results of operations for the first three months of fiscal 2013 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods.
New Accounting Standards Recently Adopted	*New Accounting Standards Recently Adopted* Effective January 1, 2013 the Company adopted the accounting guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company elected to present the information in the notes to the Company’s unaudited condensed consolidated financial statements. Effective January 1, 2013 the Company adopted the accounting standard which requires an entity to provide enhanced disclosures about certain financial instruments and derivative instruments that are offset in the statement of financial position or that are subject to enforceable master netting arrangements. The adoption did not have any impact on the Company’s unaudited condensed consolidated financial statements.
