Company and Basis of Presentation | |
Company | |
Calix, Inc. (together with its subsidiaries, “Calix,” the “Company,” “our,” “we,” or “us”) was incorporated in August 1999, and is a Delaware corporation. The Company is a leading global provider of broadband communications access systems and software for fiber- and copper-based network architectures that enable communications service providers ("CSPs") to transform their networks and connect to their residential and business subscribers. The Company enables CSPs to provide a wide range of revenue-generating services, from basic voice and data to advanced broadband services, over legacy and next-generation access networks. The Company focuses solely on CSP access networks, the portion of the network that governs available bandwidth and determines the range and quality of services that can be offered to subscribers. The Company develops and sells carrier-class hardware and software products, which the Company refers to as the Unified Access portfolio, which are designed to enhance and transform CSP access networks to meet the changing demands of subscribers rapidly and cost-effectively. | |
Basis of Presentation | |
The accompanying unaudited condensed consolidated financial statements, including the accounts of Calix, Inc. and its wholly-owned subsidiaries, have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. generally accepted accounting principles (“GAAP”) can be condensed or omitted. In the opinion of management, the financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Company’s financial position and operating results. All significant intercompany balances and transactions have been eliminated in consolidation. The Condensed Consolidated Balance Sheet at December 31, 2013 has been derived from the audited financial statements at that date. | |
The results of the Company’s operations can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year or any future periods. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited financial statements included in the Company’s Form 10-K for the year ended December 31, 2013. | |
The Company's fiscal year begins on January 1st and ends on December 31st. Quarterly periods are based on a 4-4-5 fiscal calendar with the first, second and third fiscal quarters ending on the 13th Saturday of each fiscal period. As a result, the Company had one fewer day in the nine months ended September 27, 2014 than in the nine months ended September 28, 2013, and the same number of days in the three months ended September 27, 2014 as in the three months ended September 28, 2013. The preparation of financial statements in conformity with GAAP for interim financial reporting requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. |

Significant Accounting Policies | |
The Company’s significant accounting policies are disclosed in our Annual Report on Form 10-K for the year ended December 31, 2013. Our significant accounting policies did not change during the nine months ended September 27, 2014. | |
Recent Accounting Pronouncements | |
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which provides guidance for revenue recognition. ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. Additionally, it supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. 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 the previous 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. The standard will be effective for the Company in the first quarter of fiscal 2017. Early adoption is not permitted. The Company is currently assessing the potential impact on its financial statements from adopting this new guidance. | |
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) ("ASU 2013-11"), which provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard, the Company’s unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. The accounting standard update became effective for the Company in the first quarter of 2014. As the Company’s disclosures already conform to the required presentation, adoption of this standard did not impact the financial position or results of operations of the Company. |

Cash, Cash Equivalents and Marketable Securities | |||||||||||||||||
The Company has invested its excess cash primarily in money market funds and highly liquid corporate debt instruments. The Company considers all investments with maturities of three months or less when purchased to be cash equivalents. Marketable securities represent highly liquid debt instruments with maturities greater than 90 days at date of purchase. Marketable securities with maturities greater than one year are classified as current because management considers all marketable securities to be available for current operations. | |||||||||||||||||
The Company’s investments have been classified and accounted for as available-for-sale. Such investments are recorded at fair value and unrealized holding gains and losses are reported as a separate component of accumulated other comprehensive income in stockholders’ equity until realized. Realized gains and losses on sales of marketable securities, if any, are determined on the specific identification method and are reclassified from accumulated other comprehensive income to results of operations as other income (expense). | |||||||||||||||||
The Company, to date, has not determined that any of the unrealized losses on its investments are considered to be other-than-temporary. The Company reviews its investment portfolio to determine if any security is other-than-temporarily impaired, which would require the Company to record an impairment charge in the period any such determination is made. In making this judgment, the Company evaluates, among other things, the duration and extent to which the fair value of a security is less than its cost; the financial condition of the issuer and any changes thereto; and the Company’s intent and ability to sell, or whether the Company will more likely than not be required to sell the security before recovery of its amortized cost basis. The Company has evaluated its investments as of September 27, 2014 and has determined that no investments with unrealized losses are other-than-temporarily impaired. No investments have been in a continuous loss position greater than one year | |||||||||||||||||

Fair Value Measurements | |||||||||||||
In accordance with Accounting Standard Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures, (“ASC Topic 820”), the Company measures its cash equivalents and marketable securities at fair value on a recurring basis. ASC Topic 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, ASC Topic 820 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: | |||||||||||||
Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. | |||||||||||||
Level 2 – Observable inputs other than quoted prices included in Level 1 for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-driven valuations in which all significant inputs and significant value drivers are observable in active markets. | |||||||||||||
Level 3 – Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. | |||||||||||||
The following table sets forth the Company's financial assets measured at fair value on a recurring basis as of September 27, 2014 and December 31, 2013, based on the three-tier fair value hierarchy (in thousands): | |||||||||||||

The fair values of money market funds classified as Level 1 were derived from quoted market prices as active markets for these instruments exist. The fair values of corporate debt securities and commercial paper classified as Level 2 were derived from quoted market prices for similar instruments indexed to prevailing market yield rates. The Company has no level 3 financial assets. The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 27, 2014 and September 28, 2013. |

Goodwill | |||||||||||||||||||||||||
Goodwill was recorded as a result of the Company's acquisitions of Occam Networks, Inc. (“Occam”) in February 2011 and Optical Solutions, Inc. ("OSI") in February 2006. This goodwill is not deductible for tax purposes, and there have been no adjustments to goodwill since the acquisition dates. | |||||||||||||||||||||||||
Goodwill is not amortized but instead is subject to an annual impairment test or more frequently if events or changes in circumstances indicate that it may be impaired. We evaluate goodwill on an annual basis at the end of the second quarter of each year. Management has determined that we operate as a single reporting unit and, therefore, evaluates goodwill impairment at the enterprise level. Management assessed qualitative factors to determine whether it was more likely than not (that is, a likelihood of more than 50 percent) that the fair value of the Company was less than its carrying amount, including goodwill, as of June 28, 2014. In assessing the qualitative factors, management considered the impact of these key factors: macro-economic conditions, industry and market environment, overall financial performance of the Company, cash flow from operating activities, market capitalization and stock price. Management concluded that the fair value of the Company was more likely than not greater than its carrying amount as of June 28, 2014. As such, it was not necessary to perform the two-step goodwill impairment test at the time. | |||||||||||||||||||||||||
At the end of the third quarter of 2014, management reviewed events and changes to its business subsequent to the 2014 annual impairment test and concluded that there were no indicators of impairment to the carrying value of goodwill during the three months ended September 27, 2014. As of September 27, 2014, there was no impairment to the carrying value of the Company's goodwill. | |||||||||||||||||||||||||

Litigation | |||||||||||||||||
From time to time, the Company is involved in various legal proceedings arising from the normal course of business activities. | |||||||||||||||||
On September 16, 2010, the Company, two direct, wholly-owned subsidiaries of the Company, and Occam entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”). In response to the announcement of the Merger Agreement on October 6, 2010, a purported class action complaint was filed by stockholders of Occam in the Delaware Court of Chancery: Steinhardt v. Howard-Anderson, et al. (Case No. 5878-VCL). On November 24, 2010, these stockholders filed an amended complaint (the “amended Steinhardt complaint”). The amended Steinhardt complaint named Occam (which has since been merged into Calix) and the members of the Occam board of directors as defendants. The amended Steinhardt complaint did not name Calix as a defendant. | |||||||||||||||||
The amended Steinhardt complaint sought injunctive relief rescinding the merger transaction and an award of damages in an unspecified amount, as well as plaintiffs' costs, attorney's fees, and other relief. | |||||||||||||||||
The merger transaction was completed on February 22, 2011. On January 6, 2012, the Delaware court ruled on a motion for sanctions brought by the defendants against certain of the lead plaintiffs. The Delaware court found that lead plaintiffs Michael Steinhardt, Steinhardt Overseas Management, L.P., and Ilex Partners, L.L.C., collectively the “Steinhardt Plaintiffs,” had engaged in improper trading of Calix shares, and dismissed the Steinhardt Plaintiffs from the case with prejudice. The court further held that the Steinhardt Plaintiffs are: (i) barred from receiving any recovery from the litigation, (ii) required to self-report to the SEC, (iii) directed to disclose their improper trading in any future application to serve as lead plaintiff, and (iv) ordered to disgorge trading profits of $0.5 million, to be distributed to the remaining members of the class of former Occam stockholders. The Delaware court also granted the motion of the remaining lead plaintiffs, Herbert Chen and Derek Sheeler, for class certification, and certified Messrs. Chen and Sheeler as class representatives. The certified class is a non-opt-out class consisting of all owners of Occam common stock whose shares were converted to shares of Calix on the date of the merger transaction, with the exception of the defendants in the Delaware action and their affiliates. Chen and Sheeler, on behalf of the class of similarly situated former Occam stockholders, continue to seek an award of damages in an unspecified amount. | |||||||||||||||||
Fact discovery in the case closed on April 30, 2013. On June 11, 2013, the plaintiffs filed their Second Amended Class Action Complaint for Breach of Fiduciary Duty (“Second Amended Complaint”). The Second Amended Complaint adds Occam's former CFO as a defendant, and alleges that each of the defendants breached their fiduciary duties by failing to attempt to obtain the best purchase price for Occam and failing to disclose certain allegedly material facts about the merger transaction in the preliminary proxy statement and prospectus included in the Registration Statement on Form S-4 filed with the SEC on November 2, 2010. | |||||||||||||||||
On July 17, 2013, attorneys representing all of the defendants named in the Second Amended Complaint filed Defendants' Opening Brief in Support of Their Motion for Summary Judgment, arguing that all defendants are entitled to summary judgment on all counts of the Second Amended Complaint. Plaintiffs' answering brief to the motion for summary judgment was filed on September 3, 2013, and defendants' reply brief was filed on October 4, 2013. A hearing on the motion for summary judgment was held on December 6, 2013. | |||||||||||||||||
On April 8, 2014, the Court of Chancery of the State of Delaware issued an Opinion granting in part and denying in part the Defendants’ Motion for Summary Judgment. The court granted summary judgment in favor of those defendants who served solely as directors of Occam with respect to all claims alleging improper actions in connection with the Occam sale process. The ruling also granted summary judgment on all claims as to Occam, the corporate entity. The court left in place process-based claims against Occam’s former CEO and CFO, and also declined to grant summary judgment on separate claims that the director and officer defendants breached their fiduciary duties by issuing a proxy statement for Occam’s stockholder vote that allegedly contained misleading disclosures and had material omissions. | |||||||||||||||||
On June 12, 2014, the plaintiffs filed a Motion to Compel Production of Documents by Defendants and Jefferies & Company, Inc. and For Sanctions Against Defendants. This motion sought additional documents from defendants and from Jefferies, Occam’s former advisor, and requested that the court impose severe sanctions, up to and including a finding of liability against defendants. Defendants have rejected the suggestion that any additional documents should be produced and vigorously opposed the imposition of any sanctions. On September 3, 2014, the court denied the motion without prejudice as to defendants, directed counsel for the defendants to provide an affidavit clarifying the prior conduct of discovery, and ordered discovery into defendants’ document collection and review methodologies. The court also ordered Jefferies to produce additional documents. Those proceedings are ongoing. | |||||||||||||||||
On October 17, 2014, both parties filed expert witness reports. | |||||||||||||||||
The Company continues to believe that the allegations in the Second Amended Complaint are without merit and intends to continue to vigorously contest the action as it moves forward toward trial. However, there can be no assurance that the defendants will be successful in defending this ongoing action. In addition, the Company has obligations, under certain circumstances, to hold harmless and indemnify each of the former Occam directors and officers against judgments, fines, settlements and expenses related to claims against such directors and otherwise to the fullest extent permitted under Delaware law and Occam's bylaws and certificate of incorporation. Such obligations may apply to this lawsuit and may ultimately result in the payment of indemnification amounts by the Company. The plaintiffs have not communicated any specific demand for damages. At this time, the Company is unable to quantify its indemnification risk, and an adverse result at trial could have a material adverse effect on the Company’s business, operating results or financial condition. The trial is scheduled for February 16, 2015. | |||||||||||||||||
The Company is not currently a party to any other legal proceedings that, if determined adversely to the Company, would individually or in the aggregate have a material adverse effect on the Company's business, operating results or financial condition. |

For all periods presented, unvested restricted stock awards are included in the calculation of weighted-average common shares outstanding because such shares are participating securities; however, the impact was immaterial. | |||||||||||||||||
Basic net (loss) income per common share is calculated by dividing net (loss) income by the weighted-average number of common shares outstanding during the reporting period. Diluted net (loss) income per common share is calculated by using the weighted-average number of common shares outstanding during the period, increased to include the number of additional shares of common stock that would have been outstanding if the shares of common stock underlying our outstanding dilutive stock options, restricted stock units, performance restricted stock units and purchase rights under the ESPP had been issued. The dilutive effect of these common stock equivalents is reflected in diluted earnings per common share by application of the treasury stock method. | |||||||||||||||||
Potentially dilutive shares are excluded from the computation of diluted net income (loss) per common share when their effect is antidilutive. These antidilutive shares were primarily from stock options, restricted stock units and performance restricted stock awards. In periods when we have incurred a net loss, diluted net loss per common share is the same as basic net loss per common share since the effect of all potentially dilutive securities is antidilutive. |

Equity Incentive Plans | |||||||||
The Company maintains three equity incentive plans, the 2000 Stock Plan, the 2002 Stock Plan and the 2010 Equity Incentive Award Plan (together, the “Plans”). These plans were approved by the stockholders and are described in the Company’s Form 10-K filed with the SEC on February 20, 2014. The Company also maintains a Long Term Incentive Program, under the 2010 Equity Incentive Award Plan. Under the Long Term Incentive Program, certain key employees of the Company are eligible for equity awards based on the Company’s stock price performance. To date, awards granted under the Plans consist of stock options, restricted stock units ("RSUs"), restricted stock awards ("RSAs"), and performance restricted stock units ("PRSUs"). | |||||||||
Stock Options | |||||||||
During the three months ended September 27, 2014, the Company granted 329,000 stock options at a weighted-average grant date fair value of $4.20 per share. During the nine months ended September 27, 2014, the Company granted 880,000 stock options at a weighted-average grant date fair value of $4.34 per share. During the three months ended September 27, 2014, 43,055 stock options were exercised at a weighted-average exercise price of $6.73 per share. During the nine months ended September 27, 2014, 71,866 stock options were exercised at a weighted-average exercise price of $5.97 per share. As of September 27, 2014, unrecognized stock-based compensation expense of $6.7 million related to stock options, net of estimated forfeitures, was expected to be recognized over a weighted-average period of 2.7 years. | |||||||||
Restricted Stock Units | |||||||||
During the three months ended September 27, 2014, 115,433 RSUs were granted with a weighted-average grant date fair value of $8.40 per share. During the nine months ended September 27, 2014, 794,829 RSUs were granted with a weighted-average grant date fair value of $8.71 per share. During the three months ended September 27, 2014, 194,046 RSUs vested, net of shares withheld at the then-current value equivalent to the employees' minimum statutory obligation for applicable income and other employment taxes, and were converted to an equivalent number of shares of common stock. Taxes withheld from employees of $0.9 million were remitted to the relevant taxing authorities during the three months ended September 27, 2014. During the nine months ended September 27, 2014, 419,797 RSUs vested, net of shares withheld at the then-current value equivalent to the employees' minimum statutory obligation for applicable income and other employment taxes, and were converted to an equivalent number of shares of common stock. Taxes withheld from employees of $1.7 million were remitted to the relevant taxing authorities during the nine months ended September 27, 2014. As of September 27, 2014, unrecognized stock-based compensation expense of $13.0 million related to RSUs, net of estimated forfeitures, was expected to be recognized over a weighted-average period of 2.6 years. | |||||||||
Performance Restricted Stock Units | |||||||||
In 2012, the Company commenced granting PRSUs to its executives with two-year and three-year performance periods. The performance criterion is based on the relative total shareholder return (“TSR”) of Calix common stock as compared to the TSR of the Company’s peer group. The TSR is calculated by dividing (a) the average closing trading price for the 90-day period ending on the last day of the applicable performance period by (b) the average closing trading price for the 90-day period immediately preceding the first day of the applicable performance period. This TSR is then used to derive the achievement ratio, which is then multiplied by the number of units in the grant to derive the common stock to be issued for each performance period, which may equal from zero percent (0%) to two hundred percent (200%) of the target award. | |||||||||
During the three months ended September 27, 2014, no PRSUs were granted. During the nine months ended September 27, 2014, the Company granted 144,000 PRSUs with a weighted-average grant date fair value of $8.00 per unit. During the three months ended September 27, 2014, no PRSUs were converted to shares of common stock. During the nine months ended September 27, 2014, 129,164 PRSUs vested and were converted into 94,249 shares of common stock, net of shares withheld at the then-current value equivalent to the employees' minimum statutory obligation for applicable income and other employment taxes. Taxes withheld from employees of $0.5 million were remitted to the relevant taxing authorities during the nine months ended September 27, 2014. As of September 27, 2014, unrecognized stock-based compensation expense of $1.4 million related to PRSUs, net of estimated forfeitures, was expected to be recognized over a weighted-average period of 1.3 years. | |||||||||
Restricted Stock Awards | |||||||||
During the three and nine months ended September 27, 2014, no RSAs were granted. Upon the vesting of RSAs during the three and nine months ended September 27, 2014, taxes withheld from employees of $0.2 million and $0.3 million, respectively, were remitted to the relevant taxing authorities. As of September 27, 2014, unrecognized stock-based compensation expense of $1.1 million related to RSAs, net of estimated forfeitures, was expected to be recognized over a weighted-average period of 0.8 years. | |||||||||
Employee Stock Purchase Plan | |||||||||
The Company’s Amended and Restated Employee Stock Purchase Plan (“ESPP”) allows employees to purchase shares of the Company’s common stock through payroll deductions of up to 15 percent of their annual compensation subject to certain Internal Revenue Code limitations. In addition, no participant may purchase more than 2,000 shares of common stock in each offering period. | |||||||||
The offering periods under the ESPP are six-month periods commencing on June 1 and December 1 of each year. The price of common stock purchased under the plan is 85 percent of the lower of the fair market value of the common stock on the commencement date and end date of each six-month offering period. As of September 27, 2014, there were 2,220,221 shares available for issuance under the ESPP. | |||||||||
There were no shares purchased under the ESPP during the three months ended September 27, 2014. During the nine months ended September 27, 2014, 353,594 shares were purchased under the ESPP. As of September 27, 2014, unrecognized stock-based compensation expense of $0.2 million related to the ESPP was expected to be recognized over a remaining service period of 2 months. | |||||||||
Stock-Based Compensation Expense | |||||||||
In accordance with ASC Topic 718, Compensation - Stock Compensation, ("ASC Topic 718"), stock-based compensation expense associated with stock options, RSUs, PRSUs, RSAs, and purchase rights under the ESPP is measured at the grant date based on the fair value of the award, and is recognized, net of forfeitures, as expense over the remaining requisite service period on a straight-line basis. | |||||||||
The Company values RSUs and RSAs at the closing market price of the Company’s common stock on the date of grant. | |||||||||
The fair value of PRSUs with a market condition is estimated on the date of award, using a Monte Carlo simulation model to estimate the TSR of the Company's stock in relation to the peer group over each performance period. Compensation cost on PRSUs with a market condition is not adjusted for subsequent changes in the Company's stock performance or the level of ultimate vesting. | |||||||||
The Company estimates the fair value of stock options at the grant date using the Black-Scholes option-pricing model. This model requires the use of the following assumptions: | |||||||||
(i) Expected volatility of the Company's common stock - Starting in the fourth quarter of 2012, the Company computes its expected volatility assumption based on a blended volatility (50% historical volatility and 50% implied volatility from traded options on the Company's common stock). The selection of a blended volatility assumption was based upon the Company's assessment that a blended volatility is more representative of the Company's future stock price trend as it weighs the historical volatility with the future implied volatility. Prior to the fourth quarter of 2012, due to the lack of a sufficient history of the Company's stock prices, the Company’s computation of expected volatility was based on the Company’s peer group in the industry in which the Company does business. | |||||||||
(ii) Expected life of the option award - Represents the weighted-average period that the stock options are expected to remain outstanding. The Company’s computation of expected life utilizes the simplified method in accordance with Staff Accounting Bulletin No. 110 ("SAB 110") due to the lack of sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term. The mid-point between the vesting date and the expiration date is used as the expected term under this method. | |||||||||
(iii) Expected dividend yield - Assumption is based on the Company's history of not paying dividends and no future expectations of dividend payouts. | |||||||||
(iv) Risk-free interest rate - Based on the U.S. Treasury yield curve in effect at the time of grant with maturities approximating the grant’s expected life. | |||||||||
The following table summarizes the weighted-average assumptions used in estimating the grant-date fair value of stock options in the periods indicated: | |||||||||

Modification of Stock Awards | |||||||||
In February 2013, the Company entered into a Transition and Separation Agreement ("Agreement") with Roger Weingarth, the Company's former Executive Vice President and Chief Operating Officer. Under the Agreement, Mr. Weingarth transitioned to the role of advisor to the Chief Executive Officer of the Company effective as of April 1, 2013, and terminated his employment with the Company on March 31, 2014 ("Termination Date"). Upon his termination, the Agreement provided for, among other things, the acceleration of the vesting of his unvested stock options, RSAs and RSUs held by him as of the Termination Date. In accordance with ASC Topic 718, total fair value of the accelerated stock awards after the modification was $0.6 million, which was recognized on a straight-line basis over the remaining service period through the Termination Date. During the three and nine months ended September 27, 2014, $0.1 million of the total fair value has been recognized in general and administrative expenses. |

Credit Facility | |
The Company had a revolving credit facility ("Prior Credit Facility") of $30.0 million with Silicon Valley Bank based upon a percentage of eligible accounts receivable, which matured on June 30, 2013. After the Prior Credit Facility matured on June 30, 2013, the Company cash collateralized any outstanding letters of credit with Silicon Valley Bank. As of September 27, 2014, the Company had $0.3 million cash restricted for collateralizing the outstanding letters of credit with Silicon Valley Bank. | |
On July 29, 2013, the Company entered into a credit agreement with Bank of America, N.A. The credit agreement is structured such that other financial institutions can at a later time become party to the credit agreement through an amendment via a syndication process (collectively, together with Bank of America, N.A., the "Lenders"). The credit agreement provides for a revolving facility in the aggregate principal amount of up to $50.0 million, which includes a $20.0 million sublimit for the issuance of letters of credit and a $10.0 million sublimit for a swingline facility. Subject to customary conditions, up to $25.0 million of the revolving facility may be converted to a term loan facility at any time prior to the maturity of the revolving facility. The revolving facility matures on July 29, 2016, but may be extended up to two times (each extension for an additional one-year period) upon mutual agreement of the Company and the Lenders. The credit facility is secured by substantially all of our assets, including our intellectual property. Proceeds of the credit facility may be used for general corporate purposes and permitted acquisitions. | |
Loans under the credit facility bear interest at an annual rate equal to the base rate plus 0.75% to 1.25% or LIBOR plus 2.00% to 2.50% based on a leverage ratio of consolidated funded indebtedness to consolidated Adjusted EBITDA (customarily defined). Interest on the revolving facility is due quarterly, and any outstanding interest and principal is due on the maturity date of the revolving facility. The Company is required to repay principal on a term loan in twenty equal quarterly payments from the date the Company enters into a term loan, and all outstanding principal and accrued interest is due on the revolving facility maturity date. Swingline loans must be repaid on the earlier of (i) ten business days after a loan is made and (ii) the revolving facility maturity date. The Company is also required to pay commitment fees of 0.25% per year on any unused portions of this facility. | |
The credit facility includes affirmative and negative covenants applicable to the Company that are typical for credit facilities of this type. Furthermore, the credit agreement requires us to maintain certain financial covenants, including a maximum consolidated leverage ratio, and a minimum consolidated liquidity ratio of cash, cash equivalents and accounts receivable to consolidated funded indebtedness. As of September 27, 2014, the Company was in compliance with these requirements. | |
The credit facility also includes customary events of default, the occurrence and continuation of which would provide the Lenders with the right to demand immediate repayment of any principal and unpaid interest under the credit facility, and to exercise remedies against us and the collateral securing the loans under the credit facility. | |
As of September 27, 2014, the Company had no outstanding letters of credit or borrowings under the credit facility. | |
The Company incurred $0.3 million of debt issuance costs that were directly attributable to the issuance of this credit facility. These costs will be amortized over three years starting from the effective date of the credit facility and are included within "other assets" in our Condensed Consolidated Balance Sheets. As of September 27, 2014, unamortized debt issuance costs were $0.2 million. |

The Company has incurred operating losses since inception and, as such, has not received a tax benefit for these losses. The income tax provision for the first nine months of 2014 consisted primarily of state and foreign income taxes and state alternative minimum tax ("AMT"). The Company continues to carry forward the AMT net operating loss ("NOL") acquired from Occam Networks, of approximately $4.9 million as of September 27, 2014, which can be used to offset future AMT taxable income. The income tax provision for the first nine months of 2013 primarily consisted of state AMT and state and foreign income taxes net of the tax benefit recorded resulting from the utilization of a portion of the AMT NOL acquired from Occam. The effective tax rates differ from the U.S. federal statutory rate of 34.0% due primarily to the tax affected change in the valuation allowance against the Company’s deferred tax assets. | |||||||||||||||||
ASC Topic 740, Income Taxes, ("ASC Topic 740"), provides for the recognition of deferred tax assets if realization of such assets is more likely than not. The Company has established and continues to maintain a full valuation allowance against its net deferred tax assets, with the exception of certain foreign deferred tax assets, as the Company does not believe that realization of those foreign assets is more likely than not. | |||||||||||||||||
As of September 27, 2014 and December 31, 2013, the Company had unrecognized tax benefits of $14.8 million and $14.4 million, respectively, none of which would affect the Company's effective tax rate if recognized. |

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"), which provides guidance for revenue recognition. ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. Additionally, it supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts, and creates new Subtopic 340-40, Other Assets and Deferred Costs-Contracts with Customers. 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 the previous 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. The standard will be effective for the Company in the first quarter of fiscal 2017. Early adoption is not permitted. The Company is currently assessing the potential impact on its financial statements from adopting this new guidance. | |
In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) ("ASU 2013-11"), which provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard, the Company’s unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. The accounting standard update became effective for the Company in the first quarter of 2014. As the Company’s disclosures already conform to the required presentation, adoption of this standard did not impact the financial position or results of operations of the Company. |
