1. Basis of Presentation | |||
The accompanying unaudited condensed consolidated financial statements have been prepared by Monolithic Power Systems, Inc. (the “Company” or “MPS”) in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted in accordance with these rules and regulations. The information in this report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2013, filed with the SEC on March 10, 2014. | |||
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. The financial statements contained in this Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2014 or for any other future period. | |||
Summary of Significant Accounting Policies | |||
There have been no changes to the Company’s significant accounting policies during the three and six months ended June 30, 2014 as compared to the significant accounting policies described in the Company’s audited consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2013. | |||
Recent Accounting Pronouncements | |||
In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The standard gives guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists, with the purpose of reducing diversity in practice. This new standard requires the netting of unrecognized tax benefits against a deferred tax asset for a loss or other carryforward that would apply in settlement of the uncertain tax positions. The Company adopted this standard in the first quarter of 2014 prospectively and the adoption did not have an impact on its consolidated financial position, results of operations or cash flows. | |||
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the new standard, entities will apply the following five-step model when evaluating revenue contracts with customers: | |||
● | Identify the contract with a customer | ||
● | Identify the performance obligations in the contract | ||
● | Determine the transaction price | ||
● | Allocate the transaction price to the performance obligations in the contract | ||
● | Recognize revenue when the entity satisfy a performance obligation | ||
The new standard is effective for annual and interim reporting periods beginning after December 15, 2016. Entities have the option of using either a full retrospective or a modified retrospective application in the adoption of this standard. The Company will adopt the standard in the first quarter of 2017 and is evaluating the transition method and the impact of the adoption on its consolidated financial position, results of operations and cash flows. |

4.Net Income per Share | |||||||||||||||||
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that would occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock, and calculated using the treasury stock method. | |||||||||||||||||
The Company’s outstanding RSUs contain forfeitable rights to receive dividend equivalents, which are accrued quarterly during the vesting periods of the RSUs and paid to the employees when the awards vest. Dividend equivalents accrued on the RSUs are forfeited if the employees do not fulfill their service requirement during the vesting periods. Accordingly, these awards are not treated as participating securities in the net income per share calculation. | |||||||||||||||||
The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share amounts): | |||||||||||||||||

For the three and six months ended June 30, 2013, approximately 123,000 and 115,000 common stock equivalents, respectively, were excluded from the calculation of diluted net income per share because their inclusion would have been anti-dilutive. |

6. Litigation | |
The Company and certain of its subsidiaries are parties to actions and proceedings in the ordinary course of business, including litigation regarding its shareholders and its intellectual property, challenges to the enforceability or validity of its intellectual property and claims that the Company’s products infringe on the intellectual property rights of others. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. The Company defends itself vigorously against any such claims. | |
O2 Micro | |
In May 2012, the United States District Court for the Northern District of California (the “District Court”) issued an order finding O2 Micro International, Ltd. (“O2 Micro”) liable for approximately $9.1 million in attorneys’ fees and non-taxable costs, plus interest, in connection with the patent litigation that the Company won in 2010. This award was in addition to the approximately $0.3 million in taxable costs that the District Court had earlier ordered O2 Micro to pay to the Company in connection with the same lawsuit. In October 2012, O2 Micro appealed the District Court’s judgment to the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”). In August 2013, the Federal Circuit affirmed O2 Micro’s liability for the full amount of the award. In September 2013, O2 Micro filed a petition for rehearing of that ruling, but the Federal Circuit denied O2 Micro’s petition for rehearing on October 16, 2013. | |
In November 2013, the Company received a cash payment of $9.5 million from O2 Micro. In January 2014, O2 Micro filed an appeal with the United States Supreme Court. Had O2 Micro been successful in obtaining a favorable ruling against the Company, the Company could have been liable to return a portion or all of the $9.5 million to O2 Micro. Accordingly, the Company recorded the $9.5 million as a current liability as of December 31, 2013. | |
In March 2014, the Supreme Court declined to hear the case. As O2 Micro had no further legal avenues to appeal, the Company released the current liability of $9.5 million and recorded the amount in litigation expense (benefit), net, in the Condensed Consolidated Statement of Operations in the first quarter of 2014. In addition, the Company incurred additional legal fees of $0.5 million in connection with the final resolution of the lawsuit. |

8. Income Taxes | |
The income tax provision for the three and six months ended June 30, 2014 was $0.5 million, or 7.3% of pre-tax income, and $0.8 million, or 4.7% of the pre-tax income, respectively. This differs from the federal statutory rate primarily because the Company’s foreign income was taxed at lower rates, and because of the benefit that the Company realized as a result of stock options exercises and the releases of RSUs and changes in the valuation allowance. | |
The income tax benefit for the three and six months ended June 30, 2013 was $(0.4) million, or (7.0%) of the pre-tax income, and $(0.6) million, or (7.6%) of the pre-tax income, respectively. This differs from the federal statutory rate primarily because the Company’s foreign income was taxed at lower rates, and because of the benefit that the Company realized from the release of an income tax reserve where the statute of limitations expired and from stock option exercises and releases of RSUs. | |
Unrecognized Tax Benefits | |
As of June 30, 2014 and December 31, 2013, the Company had unrecognized tax benefits of approximately $15.5 million and $14.9 million, respectively. As of June 30, 2014 and December 31, 2013, the Company had unrecognized tax benefits of approximately $5.3 million and $5.0 million, respectively, that would result in an adjustment to the Company’s effective tax rate if recognized after considering the valuation allowance. | |
Uncertain tax positions relate to the allocation of income and deductions among the Company’s global entities and to the determination of the research and development tax credit. The Company believes that it is reasonably possible that approximately $1.2 million of its unrecognized tax benefits may be released in 2014 as a result of a lapse of the statute of limitations. In addition, it is reasonably possible that over the next twelve-month period the Company may experience other increases or decreases in its unrecognized tax benefits. However, it is not possible to determine either the magnitude or the range of other increases or decreases at this time. | |
The Company recognizes interest and penalties, if any, related to uncertain tax positions in its income tax provision. As of June 30, 2014 and December 31, 2013, the Company had $0.9 million and $0.8 million, respectively, of accrued interest related to uncertain tax positions. | |
Income Tax Audits | |
The Company is subject to examination of its income tax returns by the IRS and other tax authorities. The Company’s U.S. Federal income tax returns for the years ended December 31, 2005 through December 31, 2007 are under examination by the IRS. In April 2011, the Company received from the IRS a Notice of Proposed Adjustment ("NOPA") relating to a cost-sharing agreement entered into by the Company and its international subsidiaries on January 1, 2004. In the NOPA, the IRS objected to the Company’s allocation of certain litigation expenses between the Company and its international subsidiaries and the amount of "buy-in payments" made by the international subsidiaries to the Company in connection with the cost-sharing agreement, and proposed to increase the Company’s U.S. taxable income according to a few alternative methodologies. In February 2012, the Company received a revised NOPA from the IRS (“Revised NOPA”). In this Revised NOPA, the IRS raised the same issues as in the NOPA issued in April 2011 but under a different methodology. Under the Revised NOPA, the largest potential federal income tax adjustment, if the IRS were to prevail on all matters in dispute, is $10.5 million, plus interest and penalties, if any. The Company responded to the IRS Revised NOPA in May 2012. In June 2013, the IRS responded and continued to disagree with the Company’s rebuttal. The Company met with the IRS Office of Appeals in March and May 2014. However, no resolutions were reached in those meetings, and both parties are scheduled to meet again in September 2014. Meanwhile, the Company agreed to grant the IRS an extension of the statute of limitations for taxable years 2005 through 2007 to September 30, 2015. | |
The IRS also audited the research and development credits carried forward into year 2005 and the credits generated in the years 2005 through 2007. The Company received a NOPA from the IRS in February 2011, proposing to reduce the research and development credits generated in year 2005 through 2007 and the carryforwards, which would then reduce the value of such credits carried forward to subsequent tax years. | |
The Company reviewed and responded to the above proposed adjustments. The Company regularly assesses the likelihood of an adverse outcome resulting from such examinations to determine the adequacy of its provision for income taxes. As of June 30, 2014, based on the technical merits of its tax return filing positions and the interactions to date with the IRS, the Company believes that it is more-likely-than-not that the resolution of the audits will not have a material impact on the Company’s consolidated financial position, results of operations and cash flows. |

11. Dividends and Dividend Equivalents | |
In June 2014, the Board of Directors approved a dividend program pursuant to which the Company intends to pay quarterly cash dividends on its common stock. Stockholders of record as of the last day of the quarter are entitled to receive the quarterly cash dividends declared by the Board of Directors, which are payable on the 15th of the following month. For the second quarter of 2014, the Board of Directors declared a cash dividend of $0.15 per share for a total of $5.8 million, which was accrued in other current liabilities as of June 30, 2014. | |
The declaration of any future cash dividend is at the discretion of the Board of Directors and will depend on the Company's financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interests of the Company's stockholders. The Company anticipates that the cash used for future dividends will come from its current domestic cash and cash generated from ongoing U.S. operations. If cash held by the Company’s international subsidiaries is needed for the payment of dividends, the Company may be required to accrue and pay U.S. taxes to repatriate the funds. | |
Under the 2004 Equity Plan, RSU awards contain rights to receive dividend equivalents, which entitle employees who hold RSUs to the same dividend value per share as holders of common stock. The dividend equivalents are accrued quarterly during the vesting periods of the RSUs and paid to the employees when the awards vest. Dividend equivalents accrued on the RSUs are forfeited if the employees do not fulfill their service requirement during the vesting periods. As of June 30, 2014, the Company accrued $0.3 million of dividend equivalents. |

12. Subsequent Event | |
Acquisition | |
In July 2014, the Company completed the acquisition of Sensima Technology SA (“Sensima”), a company located in Switzerland that develops magnetic sensors for angle measurements as well as three-dimensional magnetic field sensing. The purchase consideration consists of an upfront cash payment of $11.7 million and a cash earn-out payment of up to $8.9 million that is contingent upon Sensima achieving certain new product development and revenue goals through 2016. In addition, key employees are eligible to receive $1.7 million of time-based RSUs and up to $8.0 million of performance-based RSUs in connection with the transaction. | |
The initial accounting for the acquisition is still ongoing as of the date this Quarterly Report on Form 10-Q is issued. It is expected that intangible assets and goodwill will be recorded on the consolidated balance sheets; however, as the initial accounting for the acquisition has not been completed at the time of the issuance of these consolidated financial statements, further details have not yet been disclosed. |
