Acquisition Of Occam Networks [Abstract] |
Acquisition Of Occam Networks | 2. Acquisition of Occam Networks 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. 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. The following table represents the weighted average assumptions used to estimate fair value of stock options:
Expected volatility |  |  | 52 | %
Average expected life (years) |  |  | 3.95 |
Expected dividend yield |  |  | — |
Risk free interest rate |  |  | 1.65 | %
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. The following table summarizes the fair value of the acquired assets and assumed liabilities related to the acquisition of Occam (in thousands):
Cash and cash equivalents |  | $ | 33,631 |
Restricted cash |  |  | 1,054 |
Accounts receivable |  |  | 16,854 |
Inventory |  |  | 29,229 |
Prepaid expenses and other assets |  |  | 854 |
Property and equipment |  |  | 7,363 |
Intangible assets: |  |  |  |
Trade name (useful life of 6 months) |  |  | 2,290 |
Customer relationships (useful life of 5 years) |  |  | 51,040 |
Core developed technology (useful life of 5 years) |  |  | 25,494 |
In-process technology |  |  | 16,270 |
Purchase order backlog (useful life of 10 months) |  |  | 2,560 |
Total intangible assets |  |  | 97,654 |
Goodwill |  |  | 50,599 |
Current liabilities |  |  | (22,414 | )
Deferred revenue |  |  | (866 | )
Long-term liabilities |  |  | (890 | )
Total |  | $ | 213,068 |
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. 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. 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. 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. 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. 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. 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. 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. The results of operations of Occam are included in the Company's consolidated results of operations beginning on the February 22, 2011 acquisition date. The following pro forma information gives effect to the business combination that was completed during the quarter ended March 26, 2011 as if the business combination occurred at the beginning of the prior annual period presented. The pro forma results are not necessarily indicative of what actually would have occurred had the business combination been in effect for the period presented (table in thousands):
|  | Year Ended December 31, |
|  | 2010 |
Revenue |  | $ | 381,495 |
Net loss attributable to common stockholders |  | $ | (47,614 | )
The above Pro forma results have been adjusted for the following material adjustments, as if the business combination was completed on January 1, 2010:
| 1. | Pro forma revenue for the year ended December 31, 2010, reflects elimination of deferred revenue of $13.0 million and related deferred cost of revenue of $6.2 million, associated with Occam's products shipped but pending customer acceptance, as of December 31, 2009, as this would have been assigned little or no value, under the acquisition method of accounting.
| 2. | Pro forma net loss for the year ended December 31, 2010, includes amortization of intangible assets of $18.1 million that would have been acquired as if the business combination was completed on January 1, 2010.
