Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), and applicable Securities and Exchange Commission, or SEC, rules and regulations regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 , or 2015 Form 10-K. The condensed consolidated balance sheet as of December 31, 2015 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the anticipated results of operations for the entire year ending December 31, 2016 or any future period. Basis of Consolidation The condensed consolidated financial statements include our accounts and those of our wholly and indirectly owned subsidiaries. We eliminate all intercompany balances and transactions, including intercompany profits, in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We continually evaluate our estimates, including those related to the allocation of the purchase price associated with acquisitions; the carrying value of long-lived assets; the amortization period of long-lived assets; the carrying value, capitalization, and amortization of software and website development costs; the carrying value of goodwill and other intangible assets; the amortization period of intangible assets; the provision for income taxes and related deferred tax accounts, and realizability of deferred tax assets; certain accrued expenses; contingencies, litigation, and related legal accruals; and the value attributed to employee stock options and other stock-based awards. We base our estimates on historical experience, current business factors, and various other assumptions that we believe are necessary to consider to form a basis for making judgments. Actual results could be materially different from these estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies There have been no material changes to our significant accounting policies from those disclosed in our 2015 Form 10-K. Recently Issued Accounting Standards In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) 2016-02, Leases , which requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by operating leases and will also require disclosures designed to give users of financial statements information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance provided by ASU 2016-02 is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect of ASU 2016-06 on our consolidated financial statements and do not plan to early adopt this guidance. In May 2014, the FASB, issued ASU 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , which defers the effective date of ASU 2014-09 for all entities for one year. Consequently, the guidance provided in ASU 2014-09 will be effective for us in the first quarter of our fiscal year ending December 31, 2018. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations , which clarifies the implementation guidance on principal versus agent considerations. ASU 2016-08 is effective the same date as ASU 2014-09, Revenue from Contracts with Customers . In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies the guidance related to identifying performance obligations and licensing implementation guidance. ASU 2016-10 reduces the cost and complexity of applying certain aspects of the guidance both at implementation and on an ongoing basis. The effective date for ASU 2016-10 is the same as ASU 2014-09. We are currently in the process of evaluating the impact of the adoption of this guidance on our consolidated financial statements and have not yet selected a transition method. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting , which require all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect of ASU 2016-09 on our consolidated financial statements and do not plan to early adopt this guidance.

As of March 31, 2016 and December 31, 2015 , we did not consider any of our marketable securities to be other-than-temporarily impaired. When evaluating our investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer, our ability and intent to hold the security, and whether it is more likely than not that we will be required to sell the investment before recovery of its cost basis.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Stock Repurchases In November 2015, we announced that our Board of Directors approved the repurchase of up to $100 million of our common stock, representing approximately 7% of our outstanding common stock. The repurchase program has no expiration date, but is intended to be completed by the end of fiscal 2016. Repurchases under the program may be made through open market or privately negotiated transactions at times and in such amounts as determined by our management, subject to market conditions and in accordance with the requirements of the Securities and Exchange Commission. In February 2016, we entered into an issuer forward repurchase transaction confirmation (the ASR Agreement) with Bank of America, N.A. to repurchase common stock as part of the approved $100 million share repurchase program. Under the ASR Agreement, we paid Bank of America, N.A. $50 million and received an initial delivery of 4.2 million shares of common stock. The total number of shares to be ultimately purchased will be determined based on the volume weighted average price of our common stock during the term of the ASR Agreement (the Valuation Period). The transactions contemplated by the ASR Agreement are expected to be completed in the second fiscal quarter of 2016, but must be completed by no later than August 25, 2016. The shares of common stock delivered after the initial delivery of shares will be delivered by Bank of America, N.A. to us on the third business day following the Valuation Period. We accounted for the ASR Agreement as two separate transactions (i) approximately 4.2 million shares of common stock initially delivered which represented approximately $42.5 million was accounted for as a treasury stock transaction and (ii) the remaining $7.5 million unsettled portion of the ASR Agreement was determined to be a forward contract indexed to our common stock. The initial repurchase of shares resulted in an immediate reduction of the outstanding shares used to calculate the weighted-average common shares outstanding for basic and diluted net income (loss) per share on the delivery date. We determined that the forward contract indexed to our common stock met all of the applicable criteria for equity classification, and therefore the contract was not accounted for as a derivative. We recorded the $7.5 million unsettled portion of the ASR Agreement, which represents the implied value of the forward contract, in additional paid-in capital on the condensed consolidated balance sheet as of March 31, 2016 . Upon final settlement of the ASR Agreement, the forward contract will be reclassified from additional paid-in capital to treasury stock for the value of the additional shares received. We are authorized pursuant to the $100 million share repurchase program approved in 2015 to repurchase shares of common stock in the open market pursuant to trading plans meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934 (the Exchange Act). During the three-month period ended March 31, 2016 , we repurchased 0.2 million shares of common stock at an average price of $10.49 per share under such trading plans. Share-Based Compensation We issue share-based awards to our employees in the form of stock options, restricted stock units, and restricted stock. We also have an Employee Stock Purchase Plan, or ESPP. The following table summarizes the components of share-based compensation expense included in our condensed consolidated statements of operations: For the Three Months Ended March 31, 2016 2015 (in thousands) Cost of services $ 497 $ 372 Sales and marketing 1,618 932 Technology and development 2,793 1,709 General and administrative 3,744 2,357 Total share-based compensation $ 8,652 $ 5,370 Unrecognized share-based compensation expenses totaled $81.9 million as of March 31, 2016 , which we expect to recognize over a weighted-average time period of 3.1 years. Stock Warrants During the period ended March 31, 2016 , warrants to purchase common shares of 2,334,044 were net exercised for a total of 2,210,335 shares. There are no warrants outstanding as of March 31, 2016 .

Earnings Per Share [Abstract]
Net Loss Per Share	Net Loss Per Share We compute basic net loss per share by dividing net loss by the weighted-average number of common shares outstanding for the period. We compute diluted net loss per share giving effect to all potential dilutive common stock, including awards granted under our equity compensation plans and warrants to acquire common stock. The following table sets forth the computation of basic and diluted net loss: For the Three Months Ended March 31, 2016 2015 (in thousands, except share and per share data) Net loss $ (11,226 ) $ (9,158 ) Denominator (basic and diluted): Weighted average common shares outstanding 94,748,645 94,033,035 Net loss per share: Basic and diluted $ (0.12 ) $ (0.10 ) Potentially dilutive securities, including common equivalent shares in which the exercise price together with other assumed proceeds exceed the average market price of common stock for the applicable period, were not included in the calculation of diluted net loss per share as their impact would be anti-dilutive. The following weighted-average number of outstanding employee stock options, restricted stock units and restricted stock awards, warrants to purchase common stock, and shares purchased under our ESPP were excluded from the computation of diluted net loss per share: For the Three Months Ended March 31, 2016 2015 Stock options outstanding 11,497,626 7,287,369 Restricted stock units and restricted stock awards 2,841,861 578,657 Common equivalent shares from stock warrants 1,045,303 2,219,671 15,384,790 10,085,697

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income taxes for the interim periods presented have been included in the accompanying condensed consolidated financial statements on the basis of an estimated annual effective tax rate. Based on an estimated annual effective tax rate and discrete items, the estimated income tax benefit for the three -month periods ended March 31, 2016 and 2015 was $7.5 million and $6.0 million , respectively. The determination of the interim period income tax provision utilizes the effective tax rate method, which requires us to estimate certain annualized components of the calculation of the income tax provision, including the annual effective tax rate by entity and jurisdiction. We continually evaluate all positive and negative information to determine if our deferred tax assets are realizable in accordance with ASC 740-10-30, which states that "all available evidence shall be considered in determining whether a valuation allowance for deferred tax assets is needed". In December 2015, the proposed comprehensive settlement agreements resolving outstanding litigation relating to our past marketing representations and information security programs were approved by the Federal Trade Commission, (FTC), the representatives of a national class of consumers, and the court. As a result of these settlements, we paid $100 million in December 2015, resulting in a remaining cumulative accrual of $16 million . Based on the reserves of $96 million and $20 million recorded in the years ended December 31, 2015 and 2014, respectively, we have three years of cumulative pretax net losses. We reviewed the cumulative settlement of $116 million and determined that it was non-recurring in nature, not indicative of future performance, and, as such, would not materially affect our ability to generate taxable income in the future. In addition to excluding the impact of the non-recurring settlement amounts, we have seen improving pre-tax book income over the past 5 years and we are forecasting to continue generating pre-tax book income. As a result of the consideration of the factors discussed above, we believe that it is more likely than not that we will be able to realize our net deferred tax assets not currently subject to a valuation allowance.

If a member’s identity has been compromised, our member service team and remediation specialists will assist the member with its resolution. This includes our $1 million service guarantee, which is backed by an identity theft insurance policy, under which we will spend up to $1 million to cover certain third-party costs and expenses incurred in connection with the remediation, such as legal and investigatory fees, subject to certain terms and conditions. This insurance also covers certain out-of-pocket expenses, such as loss of income, replacement of fraudulent withdrawals, and costs associated with child and elderly care, travel, stolen purse/wallet, and replacement of documents. While we have reimbursed members for claims under this guarantee, the amounts in aggregate for the three -month periods ended March 31, 2016 and 2015 were not material. On March 13, 2014, we received a request from the FTC for documents and information related to our compliance with the consent decree we entered into in 2010 (the FTC Order). Prior to our receipt of the FTC’s request, we met with FTC Staff on January 17, 2014, at our request, to discuss issues regarding allegations that have been asserted in a whistleblower claim against us relating to our compliance with the FTC Order. On October 29, 2014, we completed our responses to the FTC’s March 13, 2014 request for information, and on January 5, 2015, we provided responses to subsequent FTC requests for additional information. On July 21, 2015 the FTC lodged, under seal, in the United States District Court for the District of Arizona, a motion seeking to hold us in contempt of the FTC Order. On December 17, 2015, we entered into a comprehensive settlement agreement with the FTC, pursuant to which we resolved all matters related to the FTC Contempt Action and provided a mechanism to fund a settlement of the Ebarle Class Action. Under the terms of the settlement, $100 million was placed into the registry of the court overseeing the FTC Contempt Action, $68 million of which was to be distributed to fund the consumer redress contemplated by the Ebarle Class Action settlement, and the remaining $32 million of which is authorized to fund consumer redress ordered by any states’ attorneys general, provided that certain conditions are met. If all or part of the $32 million is not used for that purpose, it will revert to the FTC. On January 19, 2015, plaintiffs Napoleon Ebarle and Jeanne Stamm filed a nationwide putative consumer class action lawsuit against us in the United States District Court for the Northern District of California. The plaintiffs allege that we have engaged in deceptive marketing and sales practices in connection with our membership plans in violation of the Arizona Consumer Fraud Act and seek declaratory judgment under the Federal Declaratory Judgment Act. On March 27, 2015, plaintiffs filed an amended complaint, adding an additional plaintiff, Brian Litton, adding a breach of contract claim, and expanding the class period to include all members enrolled in one of the company’s identity theft protection plans since January 1, 2010. On January 20, 2016, the court overseeing the Ebarle Class Action granted the plaintiffs’ motion for preliminary approval conditionally approving the parties’ proposed settlement agreement and allowing plaintiffs to file a second amended complaint naming Reiner Jerome Ebarle as an additional plaintiff. On February 11, 2016, the court overseeing the FTC Action entered an order allowing the $68 million to be transferred from the court's registry to the court-ordered settlement administrator in the Ebarle Class Action to fund the settlement. Notice has been sent to the class members. The deadline for class members to object was April 14, 2016, and the deadline for class members to submit claims is April 29, 2016. A hearing on final approval is scheduled for June 23, 2016. As of March 31, 2016 we have $13.0 million accrued for settlement of this claim, which was not included within the $100 million settlement paid to the FTC for settlement of the FTC Contempt Action and nationwide class action claims. In addition, we have $3.0 million accrued for a potential settlement with states attorneys general for related claims. On August 1, 2014, our subsidiaries Lemon and Lemon Argentina, S.R.L. (Lemon Argentina, and together, the Lemon Entities) filed a lawsuit in Santa Clara Superior Court in San Jose, California, against Wenceslao Casares, former General Manager of Lemon, Cynthia McAdam, former General Counsel of Lemon, and Federico Murrone, Martin Apesteguia and Fabian Cuesta, each a former employee and former member of the Board of Directors of Lemon Argentina (the Argentine Executives). The complaint alleges breaches of employment-related contracts and breaches of fiduciary duty involving each named individual’s work for third-party Xapo, Inc. and/or Xapo, Ltd. during their employment by the applicable Lemon Entity. The parties, including the Argentine Executives, engaged in mediation in August 2014 in Buenos Aires, Argentina, and again in December 2014 in San Francisco, California, but were unable to settle any claims. On January 30, 2015, the Lemon Entities filed a second amended complaint alleging breaches of employment-related contracts, breaches of fiduciary duties, and fraud, and seeking declaratory relief against Mr. Casares, Ms. McAdam, and the Argentine Executives. Mr. Casares and Ms. McAdam demurred to the Second Amended Complaint on May 1, 2015, which the court overruled in its entirety on July 2, 2015. Mr. Casares and Ms. McAdam answered the Second Amended Complaint on July 24, 2015. The Argentine Executives entered their appearances in the litigation on July 24, 2015 and filed a motion to dismiss for inconvenient forum on September 8, 2015. That motion was heard on December 4, 2015 and granted on January 4, 2016, with an order staying the action in its entirety. The Lemon Entities filed a notice of appeal on March 1, 2016. Mr. Casares also filed a cross-claim against us and Lemon, Inc. (now Lemon, LLC) on July 24, 2015, for breach of contract, breach of the implied covenant of good faith and fair dealing, conversion, unjust enrichment, and declaratory relief, all arising from the termination of his employment. He filed an amended cross-claim asserting the same causes of action on September 22, 2015. We, along with Lemon, LLC, filed a motion to dismiss the amended cross-claim on October 22, 2015. Because of the January 4, 2016 order staying the case in its entirety, the court did not rule on the motion to dismiss. Mr. Casares filed a separate complaint against us, Lemon, LLC, and Shareholder Representative Services LLC (SRS) in Delaware Chancery Court on October 7, 2015 for breach of contract and seeking a declaratory judgment. The action concerns a December 12, 2014 settlement agreement that resolved certain disputes against other former shareholders of Lemon, Inc. arising out of our December 11, 2013 Lemon acquisition. We, along with Lemon, LLC, moved to dismiss the complaint on October 28, 2015. Mr. Casares responded by filing an amended complaint on January 8, 2016. LifeLock, Inc. and Lemon, LLC moved to dismiss the amended complaint. LifeLock, Inc. and Lemon, LLC filed their brief in support of the motion to dismiss on February 24, 2016. Mr. Casares filed his opposition on March 25, 2016. LifeLock, Inc. and Lemon, LLC's reply in support of the motion is due April 25, 2016. On July 22, 2015, Miguel Avila, representing himself and seeking to represent a class of persons who acquired our securities from July 30, 2014 to July 20, 2015, inclusive, filed a class action complaint in the United States District Court for the District of Arizona. His complaint alleges that Todd Davis, Christopher Power, and we violated Sections 10(b) and 20(a) of the Securities Exchange Act by making materially false or misleading statements, or failing to disclose material facts about our business, operations, and prospects, including with regard to our information security program, advertising, recordkeeping, and our compliance with the FTC Order. The complaint seeks certification as a class action, compensatory damages, and attorney’s fees and costs. On September 21, 2015, four other Company stockholders, Oklahoma Police Pension and Retirement System, Oklahoma Firefighters Pension and Retirement System, Larisa Gassel, and Donna Thompson, and their respective attorneys all filed motions seeking to be appointed the lead plaintiff and lead counsel in this class action. On October 9, 2015, the Court appointed Oklahoma Police Pension and Retirement System and Oklahoma Firefighters Pension and Retirement System as lead plaintiffs. On October 19, 2015, the Court entered a scheduling order pursuant to which, and consistent with that order, lead plaintiffs filed an amended complaint on December 10, 2015. We, along with Mr. Davis and Mr. Power, moved to dismiss the amended complaint on January 29, 2016. A hearing on that motion to dismiss is scheduled for May 2, 2016. lead plaintiffs moved to lift a statutory discovery stay imposed by the Private Securities Litigation Reform Act on January 21, 2016. We, along with Mr. Davis and Mr. Power, opposed that motion on February 8, 2016. On April 22, 2016, the Court denied lead plaintiffs’ motion. On March 3, 2014, and March 10, 2014, two securities class action complaints were filed in the United States District Court for the District of Arizona, against us, Mr. Davis, and Mr. Power. On June 16, 2014, the court consolidated the complaints into a single action captioned In re LifeLock, Inc. Securities Litigation and appointed a lead plaintiff and lead counsel. On August 15, 2014, the lead plaintiff filed the Consolidated Amended Class Action Complaint (the Consolidated Amended Complaint), seeking to represent a class of persons who acquired our securities from February 26, 2013 to May 16, 2014, inclusive (the Class Period). The Consolidated Amended Complaint alleged that we, along with Mr. Davis, Mr. Power, and Ms. Schneider, violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, by making materially false or misleading statements, or failing to disclose material facts regarding certain of our business, operational, and compliance policies, including with regard to certain of our services, our data security program, and Mr. Davis’ compliance with the FTC Order. The Consolidated Amended Complaint alleged that, as a result, certain of our financial statements issued during the Class Period and certain public statements made by Ms. Schneider, Mr. Davis, and Mr. Power during the Class Period, were false and misleading. The Consolidated Amended Complaint sought certification as a class action, compensatory damages, and attorneys’ fees and costs. On September 15, 2014, we, along with our President, Mr. Davis, and Mr. Power, filed a motion to dismiss the Consolidated Amended Complaint. On December 17, 2014, the court dismissed the Consolidated Amended Complaint and gave the lead plaintiff 21 days to seek leave to amend. On January 16, 2015, lead plaintiff filed his Second Consolidated Amended Complaint which contained similar allegations, but no longer named Ms. Schneider as a defendant. On January 30, 2015, we, along with Mr. Davis and Mr. Power, filed a motion to dismiss the Second Consolidated Amended Complaint. On July 21, 2015, the court granted the motion to dismiss, without leave to amend, and entered judgment in our favor. On August 18, 2015, the lead plaintiff along with another shareholder, City of Hallandale Beach Police and Firefighters’ Personnel Retirement Fund, moved to vacate the judgment on the grounds that the FTC’s July 21, 2015 motion seeking to hold us in contempt of the FTC Order constituted surprise and newly discovered evidence. Plaintiffs also sought permission to file a Third Consolidated Amended Complaint. We, Mr. Davis, and Mr. Power opposed plaintiffs’ motion. On September 18, 2015, the court denied plaintiffs’ motion to vacate the July 21, 2015 judgment and plaintiffs’ request to file another complaint. On September 21, 2015, plaintiffs filed a notice of appeal with the Ninth Circuit Court of Appeals. Plaintiffs appeal from the lower court’s July 21, 2015 order dismissing the Second Consolidated Amended Complaint and entering judgment in our favor, and the court’s September 18, 2015 order denying plaintiffs’ motion to vacate that judgment. Briefing of the appeal has been completed, but oral argument on the appeal has not been set by the Ninth Circuit. On September 23, 2015, Sridhar Manthangodu, a stockholder of ours, filed a derivative complaint captioned Manthangodu v. Davis, et al., in the Superior Court of the State of Arizona, Maricopa County (Arizona Superior Court). This derivative complaint, purportedly filed on our behalf (we are named as a nominal defendant in the action), alleges that certain of our directors (the Director Defendants) violated their fiduciary duties to LifeLock stockholders by failing to ensure that we complied with the FTC Order. According to the complaint, the Director Defendants’ alleged breach of their fiduciary oversight duties has exposed us to “material liability,” because we must defend against the FTC’s July 21, 2015 motion seeking to hold us in contempt of the FTC Order, and the shareholder securities class action filed on July 22, 2015 discussed above. The complaint seeks unspecified monetary damages, a return to the company of all personal compensation received by the Director Defendants, as well as unspecified corporate governance reforms. On October 16, 2015, the parties jointly moved for a transfer of this matter to the Commercial Court of Maricopa County Superior Court. On October 20, 2015, that motion was granted and the action was transferred to the Commercial Court. On November 17, 2015, and December 16, 2015, the Court held status conferences. At these conferences, the parties stated that they were engaged in continued discussions aimed at potential resolution of the action. On December 24, 2015 the Court issued an Order directing the parties to continue to engage in settlement discussions, including at a mediation before former Chief Justice of the Arizona Supreme Court, Stanley Feldman. The Court also appointed Plaintiff Manthangodu lead plaintiff and his counsel lead counsel. The parties have engaged in multiple mediation sessions before Justice Feldman and made substantial progress. Negotiations are ongoing. If the parties reach agreement on all terms, the agreement will be subject to approval by the Board of Directors. If the Directors approve any settlement of the derivative suit, that settlement will then be subject to Court approval. We cannot guarantee that we will be able to settle the suit or that any settlement would be approved. Following the filing of the Manthangodu action discussed above, additional substantively similar Stockholder derivative actions were purportedly filed on our behalf against certain of our current and former directors and officers (the Individual Defendants) in the United States District Court for the District of Arizona (the Arizona Federal Court), the Delaware Court of Chancery (the Delaware Court), and the Arizona Superior Court. On October 28, 2015, a stockholder filed a derivative complaint captioned Gassel v. Davis, et al., in the Arizona Federal District Court. On November 19, 2015 and November 25, 2015, two stockholders filed derivative complaints captioned Stein v. Davis, et al. and John L. Munson Revocable Trust v. Davis, et al., respectively, in the Delaware Court of Chancery. On January 22, 2016, January 26, 2016, and February 1, 2016, three stockholders filed derivative complaints captioned, City of Pontiac General Employees’ Retirement Sys. v. Guthrie, et al.; Liang Jiawei v. Davis, et al.; and Russell Sprouse v. Davis, et al., in the Arizona Superior Court. Like the Manthangodu action, all of these actions allege that the Individual Defendants breached their fiduciary duties to LifeLock stockholders by failing to ensure that our business and operations complied with the FTC Order and/or by making materially false or misleading statements, or failing to disclose material facts regarding our business, operations, and prospects, including with regard to certain of our services, our data security program, and our compliance with the FTC Order, and make other related allegations and claims. Like the Manthangodu action, these actions seek relief including unspecified monetary damages, restitution to the Company from the Individual Defendants, certain corporate governance reforms, attorneys’ fees and costs, and/or punitive damages. On January 8, 2016, we and the Individual Defendants moved to stay the Gassel action as duplicative of the first-filed Manthangodu action. On April 13, 2016, the Arizona Federal Court granted a non-indefinite stay of the action and directed us to file a status update on the Manthangodu action on July 12, 2016. On February 11, 2016, the Arizona Superior Court entered an order consolidating the Sprouse Action with the first-filed Manthangodu Action. On February 24, 2016, the Court entered an order consolidating the City of Pontiac and Jiawei actions with the Manthangodu and Sprouse actions. The consolidated action is captioned In re: LifeLock, Inc. Derivative Litigation. On February 22, 2016, plaintiffs Sprouse and City of Pontiac each filed motions seeking to modify the Court’s December 24, 2016 order appointing lead counsel and lead plaintiff to add Sprouse and City of Pontiac as co-lead plaintiff and their respective counsel as co-lead counsel. Lead plaintiff Manthangodu opposed those motions on March 10, 2016. On March 18, 2016 the Court set a hearing on these motions for May 13, 2016, which hearing was later vacated by the Court on April 7, 2016, upon stipulation of defendants and plaintiffs Manthangodu, Sprouse, City of Pontiac, and Jiawei. Also on March 18, 2016, the plaintiffs in the Stein and Munson actions voluntarily dismissed their actions. On March 23, 2016, these plaintiffs jointly filed a derivative complaint captioned, Stein and Munson v. Davis et al., in the Arizona Superior Court against certain of our current directors. This derivative complaint makes the same allegations and seeks the same relief as in the original actions filed in the Delaware Chancery Court. On April 7, 2016, the Court entered an Order consolidating the Stein and Munson action with the previously consolidated Manthangodu, Sprouse, Jiawei, and City of Pontiac actions. We are subject to other legal proceedings and claims that have arisen in the ordinary course of business. Although there can be no assurance as to the ultimate disposition of these matters, we believe, based upon the information available at this time, that, except as disclosed above, a material adverse outcome related to the matters is neither probable nor estimable.

Summary of Significant Accoun18

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), and applicable Securities and Exchange Commission, or SEC, rules and regulations regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 , or 2015 Form 10-K. The condensed consolidated balance sheet as of December 31, 2015 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by U.S. GAAP. The accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the anticipated results of operations for the entire year ending December 31, 2016 or any future period.
Basis of Consolidation	The condensed consolidated financial statements include our accounts and those of our wholly and indirectly owned subsidiaries. We eliminate all intercompany balances and transactions, including intercompany profits, in consolidation.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We continually evaluate our estimates, including those related to the allocation of the purchase price associated with acquisitions; the carrying value of long-lived assets; the amortization period of long-lived assets; the carrying value, capitalization, and amortization of software and website development costs; the carrying value of goodwill and other intangible assets; the amortization period of intangible assets; the provision for income taxes and related deferred tax accounts, and realizability of deferred tax assets; certain accrued expenses; contingencies, litigation, and related legal accruals; and the value attributed to employee stock options and other stock-based awards. We base our estimates on historical experience, current business factors, and various other assumptions that we believe are necessary to consider to form a basis for making judgments. Actual results could be materially different from these estimates.
Recently Issued Accounting Standards	In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update (ASU) 2016-02, Leases , which requires lessees to recognize the assets and liabilities on their balance sheet for the rights and obligations created by operating leases and will also require disclosures designed to give users of financial statements information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance provided by ASU 2016-02 is effective for annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect of ASU 2016-06 on our consolidated financial statements and do not plan to early adopt this guidance. In May 2014, the FASB, issued ASU 2014-09, Revenue from Contracts with Customers, which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date , which defers the effective date of ASU 2014-09 for all entities for one year. Consequently, the guidance provided in ASU 2014-09 will be effective for us in the first quarter of our fiscal year ending December 31, 2018. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations , which clarifies the implementation guidance on principal versus agent considerations. ASU 2016-08 is effective the same date as ASU 2014-09, Revenue from Contracts with Customers . In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing , which clarifies the guidance related to identifying performance obligations and licensing implementation guidance. ASU 2016-10 reduces the cost and complexity of applying certain aspects of the guidance both at implementation and on an ongoing basis. The effective date for ASU 2016-10 is the same as ASU 2014-09. We are currently in the process of evaluating the impact of the adoption of this guidance on our consolidated financial statements and have not yet selected a transition method. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting , which require all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the effect of ASU 2016-09 on our consolidated financial statements and do not plan to early adopt this guidance.
