Acquisition of Occam Networks &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On February 22, 2011, the Company completed its acquisition of Occam in a stock and cash transaction valued at approximately $213.1 million which consisted of $94.5 million of cash consideration and a value of $118.6 million of common stock and equity awards issued. In connection with the consummation of the acquisition, each outstanding share of common stock of Occam was converted, effective as of February 22, 2011, into the right to receive: (i) 0.2925 shares of Calix common stock and (ii) $3.8337 in cash. In addition, (a) each outstanding Occam stock option or restricted stock unit as of immediately prior to the effective time of the acquisition which was or became vested as of the effective time of the acquisition with a per share exercise price that was less than (i) $3.8337 plus (ii) 0.2925 multiplied by the average volume weighted average trading price of Calix common stock during the five consecutive trading days ending on the trading day that was one day before the effective time of the acquisition, such amount being referred to as the cash-out consideration and (b) Occam options or restricted stock units held by persons who were not Occam employees or consultants immediately prior to the effective time of the acquisition were automatically cancelled and extinguished and the vested portion thereof was automatically converted into the right to receive the cash-out consideration for the aggregate number of shares of Occam common stock that were issuable upon the exercise of such stock options or restricted stock units, less any applicable per share exercise price. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Unvested portions of each outstanding Occam stock option or restricted stock unit held by Occam employees who continued to be employed by Calix or its subsidiaries after the effective time of the merger transaction that were not cashed out and cancelled as described above were, at the effective time, automatically converted into options or restricted stock units, as the case may be, for Calix common stock, subject to adjustments in accordance with the compensatory award exchange ratio, and subject to the terms and conditions of such award prior to the effective time, including vesting and exercisability. The fair value of Calix stock options and restricted stock units issued to employees of Occam was $5.8 million including those accelerated for Occam executives associated with their severance agreements which were executed subsequent to the acquisition date. The fair value of options was estimated using a Black-Scholes option pricing model. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The acquisition of Occam has been accounted for under the acquisition method of accounting which requires the acquired assets and assumed liabilities to be recorded based on their estimated fair values. The fair values assigned to the acquired assets and assumed liabilities are based on valuations using management's best estimates and assumptions utilizing the best information available at the time these consolidated financial statements were issued. During the measurement period (which is not to exceed one year from the acquisition date), the Company is required to retrospectively adjust the provisional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets or liabilities as of that date. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company has finalized the fair values of the acquired assets and assumed liabilities and has closed the measurement period as of June 25, 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Trade names represent acquired product names which are expected to have a useful life of six months. Customer relationships represent agreements with existing Occam customers and have estimated useful lives of five years. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Core developed technology represents technology that has reached technological feasibility and includes Occam's primary product line. The fair value of the core developed technology is determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Core developed technology will be amortized over its estimated useful life of five years. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In-process technology represents projects that have not reached technological feasibility at the time of the acquisition and they do not have a finite useful life. In-process technology will be impaired, if abandoned, or amortized in future periods, depending on the ability of the Company to use the research and development in future periods. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Acquired backlog represents goods and services that the Occam customers are contractually obligated to receive in the future and is expected to have a ten month life. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;During the year ended December 31, 2011, the Company incurred $20.0 million of merger-related expenses, resulting from the required revaluation of inventory to its estimated fair value and an associated write-down of inventory determined as excess and obsolete. The Company also incurred $12.9 million of merger-related expenses in the twelve months ended December 31, 2011, related to severance for terminated employees and salaries for transitional employees, expenses associated with consolidating facilities, transaction costs for financial advisory, legal and accounting services, and stock-based compensation expense primarily related to accelerated vesting for certain Occam executives who terminated subsequent to the acquisition date. The Company does not anticipate recording any future merger-related expenses. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Adjustments recorded during the measurement period through June 25, 2011, primarily consisted of assets recorded for legal fees incurred by Occam prior to the acquisition that have subsequently been reimbursed or are expected to be reimbursed under pre-existing insurance policies. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The premium paid by the Company in this transaction is attributable to the strategic benefits of creating a more competitive and efficient company, more capable of competing against larger telecommunications equipment companies in more markets and the significant cost synergies that would be obtained by the combined organization. The combined organization is expected to provide communications service providers globally with an enhanced portfolio of advanced broadband access systems, and accelerate innovation across the expanded Calix Unified Access portfolio. The acquisition is expected to result in more access options over both fiber and copper for communications service providers to deploy, which could expedite the proliferation of advanced broadband services to both residential and business subscribers, including such services as high-speed Internet, Internet protocol television, or IPTV, Voice over internet protocol or VOIP, Ethernet business services, and other advanced broadband applications. &lt;/font&gt;&lt;/p&gt;

In addition, the Company did not experience any significant realized gains or losses on its investments through December 31, 2011. The Company generally reviews investments held with unrealized losses to determine if the loss is other-than-temporary. As of December 31, 2010, the Company determined that it had the ability and intent to hold these investments for a period of time sufficient for a recovery of fair market value and did not consider the investments to be other-than-temporarily impaired. The Company's money market funds maintained a net asset value of $1.00 for all periods presented. Net unrealized gains/losses are recorded to other comprehensive income (loss) in the Company's consolidated balance sheets. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:CashCashEquivalentsAndMarketableSecuritiesTextBlock>

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company leases its primary office space in Petaluma, California under a lease agreement that extends through February 2014. The Company received a lease incentive consisting of $1.2 million in leasehold improvements provided by the lessor. The Company has capitalized the full amount of the lease incentive and this incentive is being amortized through rent expense over the lease term. Payments under the Company's operating leases that escalate over the term of the lease are recognized as rent expense on a straight-line basis. The above table also includes future minimum lease payments for our facilities in Minneapolis, Minnesota, Acton, Massachusetts, Nanjing, China, Richardson, Texas and Fremont and Santa Barbara, California, which expire at various dates through 2016, and for certain equipment under non-cancelable operating lease agreements, obtained through our acquisition of Occam, which expire at various dates through 2015. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Rent expense was $3.6 million, for the year ended December 31, 2011, and $2.1 million for each of the years ended December 31, 2010 and 2009. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Purchase Commitments &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company's primary contract manufacturers place orders for component inventory in advance based upon the Company's build forecasts in order to reduce manufacturing lead times and ensure adequate component supply. The components are used by the contract manufacturers to build the products included in the build forecasts. The Company does not take ownership of the components and any outstanding orders do not represent firm purchase commitments pursuant to the Company's agreement with the contract manufacturer. The Company will provide purchase orders to its contract manufacturers in order to fulfill its monthly finished product inventory requirements. The Company incurs a liability when the manufacturer has converted the component inventory to a finished product and takes ownership of the inventory when transferred to the designated shipping warehouse. However, historically, the Company has reimbursed its primary contract manufacturer for component inventory purchases when this inventory has been rendered excess or obsolete, for example due to manufacturing and engineering change orders resulting from design changes, manufacturing discontinuation of parts by its suppliers, or in cases where inventory levels greatly exceed projected demand. The estimated excess and obsolete inventory liabilities related to such manufacturing and engineering change orders, which are included in accrued liabilities in the accompanying balance sheets, were $3.8 million and $1.0 million as of December 31, 2011 and 2010, respectively. The Company records these amounts in cost of products and services in its statement of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;As of December 31, 2011, the Company had non-cancelable outstanding purchase orders of $5.2 million for finished goods to be delivered by its contract manufacturers. The Company did not have any outstanding purchase orders as of December 31, 2010. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Accrued Warranty &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company generally provides a warranty for its hardware products for a period of one to five-years, depending on product type, from the date of shipment. The Company accrues for potential warranty claims based on the Company's historical claims experience and other relevant information. The adequacy of the accrual is reviewed on a periodic basis and adjusted, if necessary, based on additional information as it becomes available. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Activity related to the product warranty is as follows (in thousands): &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company recorded $8.5 million of accrued warranty related to the liabilities assumed with the acquisition of Occam on February 22, 2011. For more information regarding the acquisition, see Note 2 "Acquisition of Occam Networks," in the Notes to these Consolidated Financial Statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Litigation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;From time to time, the Company is involved in various legal proceedings arising from the normal course of business activities. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On September 16, 2010, the Company and two direct, wholly-owned subsidiaries of the Company, entered into an Agreement and Plan of Merger and Reorganization, or the "Merger Agreement". In response to the announcement of the Merger Agreement, on September 17, 2010, September 20, 2010 and September 21, 2010, three purported class action complaints were filed by three purported stockholders of Occam in the California Superior Court for Santa Barbara County: Kardosh v. Occam Networks, Inc., et al. (Case No. 1371748), or the Kardosh complaint; Kennedy v. Occam Networks, Inc., et al. (Case No. 1371762), or the Kennedy complaint; and Moghaddam v. Occam Networks, Inc., et al. (Case No. 1371802), or the Moghaddam complaint, respectively. The Kardosh, Kennedy and Moghaddam complaints, which are referred to collectively as the California class action complaints, are substantially similar. Each of the California class action complaints names Occam, the pre-acquisition members of the Occam board of directors and us as defendants. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The California class action complaints generally allege that the former members of the Occam board breached their fiduciary duties in connection with the acquisition of Occam by Calix, by, among other things, engaging in an allegedly unfair process and agreeing to an allegedly unfair price for the proposed merger transaction. The California class action complaints further allege that Occam and the other entity defendants aided and abetted the alleged breaches of fiduciary duty. The plaintiffs in the California class action complaints sought injunctive relief rescinding the merger transaction and damages in an unspecified amount, as well as costs, attorney's fees, and other relief. On November 2, 2010, the three California class action complaints were consolidated into a single action, with the Kardosh action becoming the lead action, and on November 19, 2010, the California Superior Court issued an order staying the California class actions in favor of a substantively identical stockholder class action pending in the Delaware Court of Chancery (see below). The California class actions remain stayed under that order. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;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, or the amended Steinhardt complaint. The amended Steinhardt complaint names Occam and the members of the Occam board of directors as defendants. The amended Steinhardt complaint does not name Calix as a defendant. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Like the California class action complaints, the amended Steinhardt complaint generally alleges that the members of the Occam board breached their fiduciary duties in connection with the acquisition of Occam by Calix, by, among other things, engaging in an allegedly unfair process and agreeing to an allegedly unfair price for the merger transaction. The amended Steinhardt complaint also alleges that Occam and the former members of the Occam board breached their fiduciary duties by 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 that Calix filed with the SEC on November 2, 2010. The amended Steinhardt complaint sought injunctive relief rescinding the merger transaction and award of damages in an unspecified amount, as well as plaintiffs' costs, attorney's fees, and other relief. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The merger transaction was completed on February 22, 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 6, 2012, the Delaware court ruled on a motion for sanctions brought by the defendants in the Delaware case 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. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 6, 2012, 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. Chen and Sheeler, on behalf of the class of similarly situated former Occam stockholders, are expected to continue to seek an award of damages in an unspecified amount. 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. On February 4, 2012, the court entered an order giving effect to the January 6, 2012 ruling, and further ordered that class members be given notice of the certification order and notice that any class member may seek to intervene in the case or to petition the court to modify the certification order. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company believes that the allegations in the California actions and the Delaware action are without merit and intends to continue to vigorously contest the actions. However, there can be no assurance that the Company, will be successful in defending these ongoing actions. In addition, the Company has obligations, under certain circumstances, to hold harmless and indemnify each of the former Occam directors 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 these lawsuits. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company is not currently a party to any other legal proceedings which, 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. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Guarantees &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company from time to time enters into certain types of contracts that contingently require it to indemnify various parties against claims from third parties. These contracts primarily relate to (i) certain real estate leases, under which the Company may be required to indemnify property owners for environmental and other liabilities, and other claims arising from the Company's use of the applicable premises, (ii) certain agreements with the Company's officers, directors, and employees, under which the Company may be required to indemnify such persons for liabilities arising out of their relationship with the Company, (iii) contracts under which the Company may be required to indemnify customers against third-party claims that a Company product infringes a patent, copyright, or other intellectual property right and (iv) procurement or license agreements, under which the Company may be required to indemnify licensors or vendors for certain claims that may be brought against them arising from the Company's acts or omissions with respect to the supplied products or technology. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Generally, a maximum obligation under these contracts is not explicitly stated. Because the obligated amounts associated with these types of agreements are not explicitly stated, the overall maximum amount of the obligation cannot be reasonably estimated. Historically, the Company has not been required to make payments under these obligations, and no liabilities have been recorded for these obligations in the Company's balance sheets. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Basic net loss per common share is calculated by dividing net loss by the weighted average number of common stock outstanding during the reporting period. For the years ended December 31, 2011, 2010 and 2009, basic and diluted net loss per share, are identical because the Company had losses from continuing operations and the impact of common equivalent shares would have been anti-dilutive and therefore excluded. For the year ended December 31, 2011, unvested restricted stock awards granted during the third quarter of fiscal 2011 are included in the calculation of basic weighted average shares because such shares are participating securities. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In accordance with ASC Topic 820, the Company measures its cash, cash equivalents and marketable securities at fair value. 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: &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Level 1&amp;#8212;Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Level 2&amp;#8212;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. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Level 3&amp;#8212;Unobservable inputs to the valuation derived from fair valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The fair value hierarchy also requires the Company to maximize the use of observable inputs, when available, and to minimize the use of unobservable inputs when determining inputs and determining fair value. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Management reviews the recognition of deferred tax assets to determine if realization of such assets is more likely than not. The realization of the Company's deferred tax assets is dependent upon future earnings. The Company has been in a cumulative loss position since inception which represents a significant piece of negative evidence. Using the more likely than not criteria specified in the applicable accounting guidance, this negative evidence cannot be overcome by positive evidence currently available to the Company and as a result the Company has established a full valuation allowance against its deferred tax assets. The Company's valuation allowance increased by $22.8 million and $1.5 million in the years ended December 31, 2011 and 2010, respectively. The valuation allowance in both 2011 and 2010 includes $0.1 million related to excess tax benefits of stock option deductions prior to the adoption of ASC Topic 718. The benefits will increase additional paid-in capital when realized. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Since inception, the Company has incurred operating losses and, accordingly, has not recorded a provision for federal income taxes for any periods presented. As of December 31, 2011, the Company had U.S. federal and state net operating losses of $560.2 million and $326.5 million. The U.S. federal net operating loss carryforwards will expire at various dates beginning in 2012 and through 2031 if not utilized. The state net operating loss carryforwards will expire at various dates beginning from 2012 and through 2031, if not utilized. In addition, as of December 31, 2011 and 2010, the Company had $35.3 million and $13.3 million in federal deductions, respectively, and $32.4 million and $11.8 million, respectively, in state deductions related to excess tax benefits from stock options which are not included in the net operating loss carryforward amounts in the table above since they have not met the realization criteria of ASC Topic 718. The tax benefits from these deductions will increase additional paid-in capital when realized. Additionally, the Company has U.S. federal, California and other U.S. states research and development credits of $15.6 million, $18.7 million and $1.7 million as of December 31, 2011, respectively. The U.S. federal research and development credits will begin to expire in 2020 and through 2031, and the California research and development credits have no expiration date. The credits related to other various U.S. states will begin to expire in 2015 and through 2026. During the year ended December 31, 2010, the Company performed a Section 382 study of the Internal Revenue Code (and similar state provisions), and a research and development credit study, and adjusted its deferred tax assets related to its net operating loss carryforwards and its research and development credits accordingly. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On January 1, 2009, the Company adopted the guidance related to accounting for uncertainty in income taxes (ASC Topic 740-10). This topic prescribes a recognition threshold and measurement attribute to the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The guidance also provides guidance on derecognition, classification, accounting in interim periods and disclosure requirements for uncertain tax positions. The standard requires the Company to recognize the financial statement effects of an uncertain tax position when it is more likely than not that such position will be sustained upon audit. The Company's adoption of ASC Topic 740-10 did not result in a cumulative effect adjustment to accumulated deficit. Upon adoption the Company recorded a cumulative unrecognized tax benefit of $9.3 million, which was netted against deferred tax assets with a full valuation allowance. In the event that any unrecognized tax benefits are recognized, the effective tax rate will not be affected. The Company will recognize accrued interest and penalties related to unrecognized tax benefits as interest expense and income tax expense, respectively, in statements of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The following table reconciles the Company's unrecognized tax benefits for the years ended December 31, 2011 and 2010 (in thousands): &lt;/font&gt;&lt;/p&gt;

(the "Company"), which was incorporated in Delaware in August 1999, is a leading provider in North America of broadband communications access systems and software for fiber- and copper-based network architectures that enable communications service providers to connect to their residential and business subscribers. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; margin-left: 2%;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Basis of Presentation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company operates on a 4-4-5 fiscal calendar which divides the year into four quarters, with each quarter grouped into two 4-week months and one 5-week month. The Company's fiscal year ends on December 31. The preparation of financial statements is in conformity with U.S. generally accepted accounting principles, which requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The accompanying 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"). In the opinion of management, the consolidated 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 preparation of financial statements in conformity with the applicable accounting guidance requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. For the Company, these estimates include, but are not limited to: allowances for doubtful accounts and sales returns, excess and obsolete inventory, allowances for obligations to its contract manufacturers, useful lives assigned to long-lived assets and acquired intangible assets, warranty costs, and contingencies. Actual results could differ from those estimates, and such differences could be material to the Company's financial position and results of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On February 22, 2011, the Company completed its acquisition of Occam Networks, Inc. ("Occam") in a stock and cash transaction valued at $213.1 million. The Company's results of operations for the year ended December 31, 2011 reflect the operations of the Occam business beginning on the February 22, 2011 acquisition date. See Note 2 "Acquisition of Occam Networks" in the notes to these consolidated financial statements for more information regarding the acquisition of Occam. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Applicable Accounting Guidance &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Any reference in these notes to applicable accounting guidance ("guidance") is meant to refer to the authoritative U.S. generally accepted accounting principles as found in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"). &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Business Combination &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company accounted for the acquisition of Occam under ASC Topic 805, "Business Combinations". Under this guidance all of the assets acquired and liabilities assumed are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and intangible assets acquired is recorded as goodwill. The fair values assigned to the acquired assets and assumed liabilities are based on valuations using management's best estimates and assumptions at the conclusion of the measurement period. During the measurement period (which is not to exceed one year from the acquisition date), the Company is required to retrospectively adjust the provisional assets or liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have resulted in the recognition of those assets or liabilities as of that date. These assumptions and estimates include a market participant's use of the asset and the appropriate discount rates for a market participant. The Company's estimates are based on historical experience and information obtained from the management of the acquired companies. The Company's significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates. The Company has finalized the fair values of the acquired assets and assumed liabilities from Occam as of June 25, 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Revenue Recognition &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company derives revenue primarily from the sale of hardware products and related software. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collection of the resulting receivable is reasonably assured. The Company will generally use purchase agreement and/or purchase order as evidence of an arrangement. Since the individual products and services meet the criteria for separate units of accounting, the Company will recognize revenue upon delivery of each product and/or services. Post-sales software support revenue and extended warranty services revenue is deferred and recognized ratably over the period during which the services are to be performed. Installation and training service arrangements are recognized upon delivery or completion of performance. These service arrangements are typically short term in nature and are largely completed shortly after delivery of the product. Revenue from package arrangements is recognized upon full delivery of the package. In instances where substantive acceptance provisions are specified in the customer agreement, revenue is deferred until all acceptance criteria have been met. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction. Payment terms to customers predominantly range from net 30 to net 90 days. The Company assesses the ability to collect from its customers based primarily on the creditworthiness and past payment history of the customer. Shipping charges billed to customers are included in revenue and the related shipping costs are included in cost of revenue. In certain cases, the Company's products are sold along with services, which include installation, training, post-sales software support and/or extended warranty services. To date, service revenue has comprised an insignificant portion of the Company's revenue, and the Company has not reported service revenue separately from product revenue in its financial statements. From time to time, the Company offers customers sales incentives, which include volume rebates and discounts. These amounts are accrued on a quarterly basis and recorded net of revenue. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company adopted Accounting Standards Update ("ASU") No. 2009-13, Topic 605&amp;#8212;&lt;i&gt;Multiple-Deliverable Revenue Arrangements &lt;/i&gt;and ASU No. 2009-14, Topic 985&amp;#8212;&lt;i&gt;Certain Revenue Arrangements that Include Software Elements &lt;/i&gt;on a prospective basis as of the beginning of 2010 for new and materially modified arrangements originating after December 31, 2009. Under the new standards, the Company allocates the total arrangement consideration to each separable element of an arrangement based on the relative selling price of each element. The Company's products and services qualify as separate units of accounting. Products are typically considered delivered upon shipment and are deemed to be non-contingent deliverables. The Company provides certain services at stated prices over a specified period of time and must meet specified performance conditions. As such, the Company has determined that its individual services are contingent deliverables. In addition, the Company provides specified packages of items considered a package arrangement which it also considers a contingent deliverable, and therefore the Company does not bill its customers until it has fully delivered the package. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The amount of product and service revenue recognized in a given period is affected by the valuation of the units of accounting for multiple-element arrangements. The Company uses vendor-specific objective evidence or VSOE of fair value for each of the units, when available. The Company has established VSOE for its training and post-sales software support services based on the normal pricing practices of these services when sold separately. In most instances, the Company is not able to establish VSOE for other deliverables in an arrangement with multiple elements. This may be due to infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish selling price of each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company's marketing strategy differs from that of its peers and its offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products' selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE. When the Company is unable to establish selling price using VSOE or TPE, the Company uses the best estimate of selling price ("BSP"). The objective of BSP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. The Company determines BSP for a product or service by considering multiple factors including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives, characteristics of targeted customers and pricing practices. The determination of BSP is made through consultation with and formal approval by management, taking into consideration the go-to-market strategy. The Company regularly reviews VSOE, TPE and BSP and maintains internal controls over the establishment and updates of these estimates. There were no material impacts during twelve months ended December 31, 2011, nor do we expect a material impact in the near term from changes in VSOE, TPE or BSP. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company enters into arrangements with certain of its customers who receive government supported loans and grants from the U.S. Department of Agriculture's Rural Utility Service ("RUS") to finance capital spending. Under the terms of an RUS equipment contract that includes installation services, the customer does not take possession and control and title does not pass until formal acceptance is obtained from the customer. Under this type of arrangement, the Company does not recognize revenue until it has received formal acceptance from the customer. For RUS arrangements that do not involve installation services, the Company recognizes revenue in accordance with the revenue recognition policy described above. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Cost of Revenue &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Cost of revenue consists primarily of finished goods inventory purchased from the Company's contract manufacturers, payroll and related expenses associated with managing the contract manufacturers' relationships, depreciation of manufacturing test equipment, warranty costs, excess and obsolete inventory costs, shipping charges, and amortization of certain intangible assets. For the year ended December 31, 2011, cost of revenue also includes merger-related expenses associated with the acquisition of Occam primarily related to a charge resulting from the required revaluation of Occam inventory to its estimated fair value and an associated write-down of acquired inventory determined as excess and obsolete. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Stock-Based Compensation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Under the provisions of ASC Topic 718, for share-based payment transactions, stock-based awards are recorded at fair value as of the grant date and recognized to expense over the employee's requisite service period (generally the vesting period), which the Company has elected to amortize on a straight-line basis. The Company adopted this guidance using the modified prospective transition method. Stock-based compensation expense has been reduced by the Company's estimated forfeitures on all unvested awards. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Warranty &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company offers limited warranties for its hardware products for a period of one or five years, depending on the product type. Warranty service revenues are deferred and recognized ratably over the period during which the services are to be performed. The Company recognizes estimated costs related to warranty activities as a component of cost of revenue upon product shipment. The estimates are based on historical product failure rates and historical costs incurred in correcting product failures. The recorded amount is adjusted from time to time for specifically identified warranty exposure. Actual warranty expenses are charged against the Company's estimated warranty liability when incurred. Factors that affect the Company's warranty liability include the number of installed units and historical and anticipated rates of warranty claims and cost per claim. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Research and Development &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Research and development costs include costs of developing new products and processes, as well as design and engineering costs. Such costs are charged to research and development expense as incurred. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Development costs related to software incorporated in the Company's products incurred subsequent to the establishment of technological feasibility are capitalized and amortized over the estimated useful lives of the related products. Technological feasibility is established upon completion of a working model. The Company, generally expenses such costs as a charge to research and development expense in the Company's statements of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Credit Risk and Inventory Supplier Concentrations &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable. Cash equivalents consist of money market funds which are invested through financial institutions in the United States. Such deposits may, at times, exceed federally insured limits. The Company has not experienced any losses in such accounts. Marketable securities consist principally of U.S. government sponsored entity bonds, commercial paper, debt securities of domestic corporations with strong credit ratings, bank certificates of deposit and U.S. Treasury bills. Management believes that the financial institutions that hold the Company's cash and investments are financially sound and, accordingly, minimal credit risk exists with respect to these cash and investments. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability or unwillingness of its customers to make required payments. The Company records a specific allowance based on an analysis of individual past-due balances. Additionally, based on its historical write-offs and collections experience, the Company records an additional allowance based on a percentage of outstanding receivables. The Company performs credit evaluations of its customers' financial condition. These evaluations require significant judgment and are based on a variety of factors including, but not limited to, current economic trends, payment history and financial review of the customer. Actual collection losses may differ from management's estimates, and such differences could be material to the Company's financial position and results of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company depends primarily on a small number of outside contract manufacturers for the bulk of its finished goods inventory. The Company generally purchases its product through purchase orders with its suppliers or contract manufacturers. While the Company seeks to maintain a sufficient reserve of its products, the Company's business and results of operations could be adversely affected by a stoppage or delay in receiving such products, the receipt of defective parts, an increase in price of such products or the Company's inability to obtain lower prices from its contract manufacturers and suppliers in response to competitive pressures. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The carrying amounts of cash and cash equivalents, trade receivables, marketable securities, accounts payable, and other accrued liabilities approximate their fair value due to their relatively short-term nature. The carrying amount of the other long-term liabilities approximates its fair value. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Cash, Cash Equivalents, and Marketable Securities &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company has invested its excess cash primarily in money market funds and highly liquid 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. Cash, cash equivalents and marketable securities are stated at amounts that approximate fair value based on quoted market prices. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;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 comprehensive loss in the stockholders' equity until realized. Should the Company determine that any unrealized losses on the investments are other-than-temporary, the amount of that impairment to be recognized in earnings will depend on whether the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current period credit loss. The Company, to date, has not determined that any of the unrealized losses on its investments are considered to be other-than-temporary. Realized gains and losses, which have been immaterial to date, are determined on the specific identification method and are reflected in results of operations. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Restricted Cash &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Restricted cash consisted of $0.8 million as of December 31, 2011, which is related to performance bonds required for the Company's RUS-funded customer contracts. As of December 31, 2010, there were no restricted cash balances as certificates of deposit were not required to back performance bonds for the Company's RUS-funded customer contracts. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Inventory &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Inventory which primarily consisted of finished goods purchased from contract manufacturers is stated at the lower of cost, determined by the first-in, first-out method, or market value. In addition, the Company will, from time to time, procure component inventory primarily as a result of manufacturing discontinuation of critical components by suppliers. The Company regularly monitors inventory quantities on hand and records write-downs for excess and obsolete inventories based on the Company's estimate of demand for its products, potential obsolescence of technology, product life cycles, and whether pricing trends or forecasts indicate that the carrying value of inventory exceeds its estimated selling price. These factors are impacted by market and economic conditions, technology changes, and new product introductions and require estimates that may include elements that are uncertain. Actual demand may differ from forecasted demand and may have a material effect on gross margins. If inventory is written down, a new cost basis is established that cannot be increased in future periods. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Deferred Cost of Revenue &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;When the Company's products have been shipped, but the product revenue associated with the arrangement has been deferred as a result of not meeting the criteria for immediate revenue recognition, the Company also defers the related inventory costs for the delivered items until all criteria are met for revenue recognition. Deferred cost of revenue also includes trial orders that are pending acceptance. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Property and Equipment &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Property and equipment are stated at cost, less accumulated depreciation, and are depreciated using the straight-line method over the estimated useful life of each asset. Computer equipment and purchased software are depreciated over three years; test equipment, is depreciated over three years; furniture and fixtures are depreciated over seven years; and leasehold improvements are depreciated over the shorter of the respective lease term or the estimated useful life of the asset. Maintenance and repairs are charged to expense as incurred. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Goodwill, Intangible Assets and Other Long-Lived Assets &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company periodically evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that a potential impairment may have occurred. If such events or changes in circumstances arise, the Company compares the carrying amount of the long-lived assets to the estimated future undiscounted cash flows expected to be generated by the long-lived assets. If the estimated aggregate undiscounted cash flows are less than the carrying amount of the long-lived assets, an impairment charge, calculated as the amount by which the carrying amount of the assets exceeds the fair value of the assets, is recorded. The fair value of the long-lived assets is determined based on the estimated discounted cash flows expected to be generated from the long-lived assets. The Company has reviewed events and changes to its business during the year and has determined that there was no impairment to its long-lived assets during 2011. In addition the Company did not incur any impairment losses for long-lived assets during 2010 and 2009. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Goodwill and other intangible assets have been recorded as a result of the Company's acquisitions of 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. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Goodwill is not amortized but instead is subject to an annual impairment test or more frequently if events or changes in circumstances indicate that they may be impaired. The Company evaluates goodwill on an annual basis as of the end of the second quarter of each fiscal year. The test for goodwill impairment is a two-step process. The first step compares the fair value of each reporting unit with its respective carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired and, therefore, the second step of the impairment test is unnecessary. The second step, used to measure the amount of impairment loss, compares the implied fair value of each reporting unit's goodwill with the respective carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss shall be recognized in an amount equal to that excess. Management has determined that it operates as a single reporting unit and therefore evaluates goodwill impairment at the enterprise level. Intangible assets with finite useful lives are amortized over their estimated useful lives, generally four to five years, and reviewed for impairment whenever events or changes in circumstances indicate an asset's carrying value may not be recoverable. The Company has completed its annual goodwill impairment test as of the second quarter of 2011 and the estimated fair value of Calix significantly exceeded its carrying value at that date. The Company has updated its evaluation of impairment indicators and has concluded that there was no impairment to the carrying value of its goodwill and intangible assets as of December 31, 2011. In addition, there were no impairment losses during 2010 and 2009. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Income Taxes &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company evaluates its tax positions and estimates its current tax exposure together with assessing temporary differences resulting from differing treatment of items not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities on the Company's balance sheets, which are estimated based upon the difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates that will be in effect when these differences reverse. In general, deferred tax assets represent future tax benefits to be received when certain expenses previously recognized in the Company's statements of operations become deductible expenses under applicable income tax laws or loss or credit carry-forwards are utilized. Accordingly, realization of the Company's deferred tax assets is dependent on future taxable income against which these deductions, losses and credits can be utilized. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company must assess the likelihood that the Company's deferred tax assets will be recovered from future taxable income, and to the extent the Company believes that recovery is not more likely than not, the Company must establish a valuation allowance. Management judgment is required in determining the Company's provision for income taxes, the Company's deferred tax assets and liabilities and any valuation allowance recorded against the Company's net deferred tax assets. The Company recorded a full valuation allowance at each balance sheet date presented because, based on the available evidence, the Company believes it is more likely than not that it will not be able to utilize all of its deferred tax assets in the future. The Company intends to maintain the full valuation allowances until sufficient evidence exists to support the reversal of the valuation allowances. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Foreign Currency Translation &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Assets and liabilities of the Company's wholly owned foreign subsidiaries are translated from their respective functional currencies at exchange rates in effect at the balance sheet date, and revenues and expenses are translated at the monthly average exchanges rates. Any material resulting translation adjustments are reflected as a separate component of stockholders' equity. Realized foreign currency transaction gains and losses were not significant during the years ended December 31, 2011, 2010 and 2009. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Recent Accounting Pronouncements &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In September 2011, the FASB issued ASU No. 2011-08, "Intangibles-Goodwill and Other" that will allow an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under these amendments, an entity would not be required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The amendments include a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The guidance is effective for fiscal years beginning after December 15, 2011 with early adoption permitted. The Company does not expect that the adoption of this update will have a material impact on its consolidated financial statements at this time. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In June 2011 and December 2011, the FASB issued ASU No. 2011-05, "Presentation of Comprehensive Income" and "Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05," respectively, which improves the comparability, consistency, and transparency of financial reporting and increases the prominence of items reported in other comprehensive income by eliminating the option to present components of other comprehensive income as part of the statement of changes in stockholders' equity. The amendments in these standards require that all non-owner changes in stockholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Under either method, adjustments must be displayed for items that are reclassified from other comprehensive income or "OCI" to net income, in both net income and OCI. The standards do not change the current option for presenting components of OCI gross or net of the effect of income taxes, provided that such tax effects are presented in the statement in which OCI is presented or disclosed in the notes to the financial statements. Additionally, the standards do not affect the calculation or reporting of earnings per share. For public entities, the amendments in these ASUs are effective for fiscal years, and interim periods within those years, beginning after December 15, 2011 and are to be applied retrospectively, with early adoption permitted. Other than changing the presentation of comprehensive income, the Company does not anticipate the adoption of this guidance in the first quarter of fiscal year 2012 to have an impact on the financial statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In May 2011, the FASB issued ASU 2011-04, which amends U.S. GAAP to conform to the measurement and disclosure requirements in International Financial Reporting Standards ("IFRS"). The amendments in this Update change the wording used to describe the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements. The amendments include the following: &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;1. Those that clarify the Board's intent about the application of existing fair value measurement and disclosure requirements &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;2. Those that change a particular principle or requirement for measuring fair value or for disclosing information about fair value measurements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In addition, to improve consistency in application across jurisdictions some changes in wording were made to ensure that U.S. GAAP and IFRS fair value measurement and disclosure requirements are described in the same way (for example, using the word shall rather than should to describe the requirements in U.S. GAAP). The amendments in this Update are to be applied prospectively and are effective during interim and annual period beginning after December 15, 2011. The Company does not believe that the adoption of this update will have a material impact on its consolidated financial statements at this time. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In December 2010, the FASB issued ASU No. 2010-29, Business Combinations (ASC Topic 805): Disclosure of Supplementary Pro Forma Information for Business Combinations. The amendments in this update specify that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination(s) that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendments in this update also expand the supplemental pro forma disclosures under Topic 805 to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. The amendments in this update are effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010. The Company has adopted this disclosure update for this Annual Report on Form 10-K. See Note 2, "Acquisition of Occam Networks" in these Notes to Consolidated Financial Statements of this Form 10-K. &lt;/font&gt;&lt;/p&gt; &lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureAndSignificantAccountingPoliciesTextBlock>

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;ASC Topic 280 establishes standards for reporting information about operating segments. The guidance requires disclosures of certain information regarding operating segments, products and services, geographic areas of operation and major customers. Segment reporting is based upon the management approach, i.e. how management organizes the Company's operating segments for which separate financial information is (1) available, and (2) evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company's chief operating decision maker is the Company's chief executive officer. The Company's chief executive officer reviews financial information presented on a Company wide basis, accompanied by disaggregated information about revenues by geographic region for purposes of allocating resources and evaluating financial performance. The Company develops, markets and sells communications access systems and software, and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the Company unit level. Accordingly, the Company is considered to be in a single reporting segment and operating unit structure. The Company's operations and substantially all of its assets are located primarily in the United States and are not allocated to any specific region. Therefore, geographic information is presented only for total revenue. The following is a summary of revenues by geographic region based upon the location to which the product was shipped (in thousands): &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On March 2, 2010, the Company's board of directors approved an amended and restated certificate of incorporation that increased the authorized common stock to 100 million shares and the authorized preferred stock to 5 million shares effective immediately prior to the completion of the Company's initial public offering on March 26, 2010. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On March 21, 2010, the Company's board of directors approved an amended and restated certificate of incorporation effecting a 2-for-3 reverse stock split of its common stock and all convertible preferred stock. The par value and the authorized shares of the common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. All issued and outstanding common stock, convertible preferred stock, warrants for common stock, warrants for preferred stock, and per share amounts contained in the financial statements have been retroactively adjusted to reflect this reverse stock split for all periods presented. The reverse stock split was effected on March 23, 2010. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On March 26, 2010, the Company completed its initial public offering in which 4,166,666 shares of common stock were sold by the Company and 2,162,266 shares of common stock were sold by existing stockholders at a public offering price of $13.00 per share. Gross proceeds of $54.2 million from the sale of 4,166,666 shares of common stock by the Company were reduced by issuance costs of $4.6 million and underwriters fees of $3.8 million. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On April 8, 2010, the Company issued and sold 949,339 shares of common stock resulting from the exercise of the underwriters' option to purchase common shares associated with the Company's initial public offering. This sale resulted in gross proceeds of $12.3 million based on an initial public offering price of $13.00 per share of common stock. Proceeds to the Company were $11.5 million which were net of underwriters' discount and offering expenses payable by the Company of $0.8 million. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On February 22, 2011, in connection with the acquisition of Occam, the Company issued 6.4 million shares of the Company's common stock, a value of $117.2 million. For more information regarding the acquisition, of Occam see Note 2 "Acquisition of Occam Networks" in the notes to these consolidated financial statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; margin-bottom: 0px; margin-left: 2%;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Preferred Stock &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The board of directors has the authority, without action by its stockholders with the exception of stockholders who hold board positions, to designate and issue up to five million shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. These rights, preferences and privileges could include dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of such series, any or all of which may be greater than the rights of common stock. The issuance of the Company's preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control of the Company or other corporate action. Subsequent to the Company's initial public offering and the conversion of all preferred stock outstanding at that date, the board of directors has not designated any rights, preference or powers of any preferred stock and no shares of preferred stock have been issued. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; margin-left: 2%;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Stock Options, Restricted Stock Units and Awards and Employee Stock Purchase Plan &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company maintains three equity incentive plans, the 2000 Stock Plan, the 2002 Stock Plan and the 2010 Equity Incentive Plan (together, the "Plans"), which allow the Company to grant stock options, restricted stock and restricted stock units to employees, directors and consultants of the Company. Under the terms of the Plans, the Company may grant incentive stock options at a price not less than 100% of the fair market value of the common stock on the date of grant and non-statutory stock options at a price not less than 85%, or, with respect to the 2002 Stock Plan and the 2010 Equity Incentive Plan, 100%, of the fair market value of the common stock on the date of grant. Additionally, options could be granted with the right to exercise those options before vesting. Upon the exercise of an option prior to vesting, the optionee is required to enter into a restricted stock purchase agreement with the Company, which provides that the Company has a right to repurchase any unvested shares at a repurchase price equal to the exercise price during the 90-day period following the termination of an individual's service with the Company for any reason. In addition, the Company has a 30-day right of first refusal if an optionee intends to sell shares acquired pursuant to options. Options granted under both Plans generally vest over four years and expire ten years from the date of grant. Given the absence of a public trading market prior to the Company's IPO, the Company's board of directors considered numerous objective and subjective factors to determine the best estimate of the fair market value of its common stock at each meeting at which stock option grants were approved. These factors included, but were not limited to, the following: contemporaneous valuations of common stock, the rights and preferences of convertible preferred stock relative to common stock, the lack of marketability of common stock, developments in the business, recent issuances of convertible preferred stock and the likelihood of achieving a liquidity event, such as an IPO, or sale of the Company, given prevailing market conditions. These determinations of fair market value were used for purposes of determining the Black-Scholes fair value of the Company's stock option awards and related stock based compensation expense prior to the Company's IPO. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On March 2, 2010, the Company's Board of Directors approved the 2010 Equity Incentive Award Plan and the Employee Stock Purchase Plan. A total of 5,666,666 shares of common stock were reserved for future issuance under these plans which became effective upon the completion of the Company's initial public offering of common stock. In addition, shares of common stock previously available for issuance under the Company's Amended and Restated 2002 Stock Plan became available for issuance under the 2010 Plan effective upon completion of the Company's initial public offering of common stock. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company had 0.4 million exercisable options as of December 31, 2010. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px; margin-left: 2%;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;i&gt;Restricted stock units &lt;/i&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In July 2009, the Company's board of directors approved a proposal to offer current employees and directors the opportunity to exchange eligible stock options for restricted stock units, or RSUs, on a one-for-one basis. Each RSU granted in the option exchange entitled the holder to receive one share of the Company's common stock if and when the RSU vests. The vesting schedule for the RSUs was as follows: 50% of the RSUs vested on the first day the trading window opened for employees that was more than 180 days following the effective date of an initial public offering which was October 26, 2010, or the First Vesting Date, and the remaining 50% of the RSUs vested on the first day the trading window opens for employees that is more than 180 days after the First Vesting Date which was in April 2011, in each case, subject to the employee's or director's continuous service to the Company through the vesting date. However, any unvested RSUs become immediately vested prior to the closing of a change in control, subject to the employee's or director's continuous service to the Company through such date. The offer was made to eligible option holders on August 14, 2009 and terminated on September 14, 2009. Only current employees and directors who were providing services to the Company as of August 14, 2009 and continued to provide services through September 14, 2009 were eligible to participate. Pursuant to the exchange, the Company subsequently canceled options for 3.4 million shares of the Company's common stock and issued an equivalent number of RSUs to eligible holders on September 23, 2009. In connection with the RSU grants, the unrecognized compensation expense related to the exchanged options was expensed over the remaining period of the original vesting period of the options exchanged. The incremental cost due to the exchange was deferred until a liquidity event, which happened with the Company's IPO, and has been recognized in accordance with the vesting periods described above. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; margin-bottom: 0px; font-size: 1px;"&gt;&amp;nbsp;&lt;/p&gt;

&lt;p style="margin-top: 0px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The fair value of the RSUs was calculated as follows (in thousands): &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Restricted stock units granted during fiscal 2011 include 42,654 units assumed in connection with the Occam acquisition. For more information on the Occam acquisition see Note 2, "Acquisition of Occam Networks", in the notes to these consolidated financial statements. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Restricted stock units granted during 2009 vested in four equal annual installments beginning on December 23, 2010, and were contingent upon the occurrence of an IPO. The unrecognized compensation cost related to this grant of $10.6 million was deferred until the Company's IPO on March 26, 2010 at which time recognition of associated expense began in accordance with the vesting period described above. These units were fully vested, and the related stock-based compensation expense was fully recognized by April 2011. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Upon vesting of certain RSUs during the year ended 2011, the RSUs were net share-settled to cover the required withholding tax and the remaining amount was converted into an equivalent number of shares of common stock. The Company withheld shares with value equivalent to the employees' minimum statutory obligation for the applicable income and other employment taxes, and remitted the cash to the appropriate taxing authorities. The total shares withheld were 485,000, which was based on the value of the RSUs on their vesting date as determined by the Company's closing stock price. Total payments for the employees' tax obligations to the taxing authorities were $10.4 million, and these are reflected as a financing activity within the Statements of Cash Flows. These net-share settlements had the effect of share repurchases by the Company as they reduced and retired the number of shares that would have otherwise have been issued as a result of the vesting and did not represent an expense to the Company. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The weighted-average grant date fair value of RSUs granted during the year ended December 31, 2011 was $21.33 per share. As of December 31, 2011, unrecognized stock-based compensation expense related to RSUs of $20.0 million is expected to be recognized over a weighted-average period of 2.9 years. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;In July 2011, the Company granted 423,000 RSAs to executives. The Company values the RSAs at fair value or the market price of the Company's common stock on the date of grant. The Company recognizes non-cash compensation expense for the fair values of these RSAs on a straight-line basis over the requisite service period of these awards. The weighted-average grant date fair value of RSAs granted during the year was $21.67 per share. As of December 31, 2011, unrecognized stock-based compensation expense related to RSAs of $7.2 million, net of estimated forfeitures, is expected to be recognized over a weighted-average period of 3.6 years. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company's 2010 Employee Stock Purchase Plan, as amended, (the "Employee Stock Purchase Plan") 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. The price of common stock purchased under the plan is equal to 85 percent of the lower of the fair market value of the common stock on the commencement date and exercise date of each of the six month offering period. Under this ESPP plan, the Company issued 176,665 shares and 244,739 shares on May 31, 2011 and November 30, 2011, at exercise price of $11.67 and $7.67, respectively. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Employee Stock Purchase Plan provides for the issuance of a maximum of 1.0 million shares of common stock of which 0.6 million shares were available for issuance as of December 31, 2011. For the year ended December 31, 2011, stock-based compensation expense related to employee stock purchase plan was $1.6 million. As of December 31, 2011, unrecognized stock-based compensation expense related to employee stock purchase plan of $0.6 million was expected to be recognized over a remaining service period of 5 months. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 18px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;&lt;b&gt;&lt;i&gt;Stock-based compensation expense &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 6px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;Stock-based compensation expense associated with stock options, restricted stock units ("RSUs"), restricted stock awards ("RSAs") and ESPP is measured at the grant date, based on the fair value of the award, and is recognized as expense over the remaining requisite service period. Total stock-based compensation of $21.6 million, $25.6 million and $9.2 million was recorded during the years ended December 31, 2011, 2010 and 2009, respectively. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;The Company estimates the fair value of stock options in accordance with ASC Topic 718 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, which is based on the Company's peer group in the industry in which the Company does business; (ii) expected life of the option award, which is calculates using the "simplified" method provided in the SEC's Staff Accounting Bulletin No. 110 and takes into consideration the grant's contractual life and vesting periods; (iii) expected dividend yield, which is assumed to be 0%, as the Company has not paid and does not anticipate paying dividends on its common stock; and (iv) the risk-free interest rate, which is based on the U.S. Treasury yield curve in effect at the time of grant with maturities equal to the grant's expected life. In addition, ASC Topic 718 requires the Company to estimate the number of options that are expected to vest. Thus, the Company applies an estimated forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior, and other factors. Further, to the extent the Company's actual forfeiture rate is different from management's estimate, stock-based compensation is adjusted accordingly. In valuing share-based awards under ASC Topic 718, significant judgment is required in determining the expected volatility of the Company's common stock and the Company's forfeiture rate. The Company values RSUs and RSAs at fair value or the market price of the Company's common stock on the date of grant. The Company recognizes stock-based compensation expense associated with stock options, RSUs and RSAs on a straight-line basis over the requisite service period of each of these awards. &lt;/font&gt;&lt;/p&gt;

&lt;p style="margin-top: 12px; text-indent: 32px; margin-bottom: 0px;"&gt;&lt;font style="font-family: Times New Roman;" class="_mt" size="2"&gt;On February 22, 2011, in connection with the acquisition of Occam (see Note 2 "Acquisition of Occam Networks" in the notes to these consolidated financial statements), the Company issued 536,190 stock options and 42,654 RSUs to certain Occam employees. The grants were in exchange for certain options and RSUs that were held by Occam employees prior to the acquisition which retained the original vesting schedule of the initial Occam grants, except for certain equity awards held by Occam executives that were accelerated in association with their severance agreements. The Company estimated the fair value of $5.9 million of the options and RSUs in accordance with ASC Topic 718. In accordance with ASC Topic 805 the Company allocated the value of $1.4 million of certain options and RSUs to consideration in the business combination with the remaining value of $4.5 million allocated to post-combination expense to be recognized over the remaining service period of the grants. &lt;/font&gt;&lt;/p&gt;

As of December 31, 2011 there was $8.1 million of total unrecognized stock-based compensation cost related to stock options, net of estimated forfeitures. This cost is expected to be recognized over a weighted average service period of 2.9 years. To the extent the actual forfeiture rate is different than what the Company has anticipated, stock-based compensation related to these awards will be different from its expectations. &lt;/font&gt;&lt;/p&gt;
