NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | ||||||||||||||||||||||||
Basis of Presentation | ||||||||||||||||||||||||
In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements (“financial statements”) of Pacific Biosciences of California, Inc. and its wholly-owned subsidiaries have been prepared on a consistent basis with the December 31, 2012 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. Certain prior year amounts in the financial statements and notes thereto have been reclassified to conform to the current year’s presentation. The financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, omit certain information and footnote disclosures necessary to present the statements in accordance with U.S. generally accepted accounting principles (“GAAP”). These financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which was filed with the SEC on March 15, 2013. The results of operations for the first nine months of fiscal 2013 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods. | ||||||||||||||||||||||||
Use of Estimates | ||||||||||||||||||||||||
The preparation of financial statements in conformity with GAAP requires us 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 revenue and expense during the reporting periods. Our estimates include, but are not limited to, useful lives assigned to long-lived assets, assumptions used to compute stock-based compensation expense and valuing warrants, value the financing derivative and long-term notes, value and recognize revenue elements, determine delivery periods for revenue recognition, and to compute provisions for income taxes, inventory, and contingencies. Actual results could differ from our estimates, and such differences could be material to our financial position and results of operations. | ||||||||||||||||||||||||
Fair Value of Financial Instruments | ||||||||||||||||||||||||
Assets and liabilities measured at fair value on a recurring basis | ||||||||||||||||||||||||
The following table sets forth the fair value of our financial assets and liabilities that were measured on a recurring basis as of September 30, 2013 and December 31, 2012, respectively: | ||||||||||||||||||||||||

All of our cash deposits and money market funds are classified within Level 1 of the fair value hierarchy because they are valued using bank balances or quoted market prices. Our investments are classified as Level 2 instruments based on market pricing and other observable inputs. None of our investments are classified within Level 3 of the fair value hierarchy. | ||||||||||||||||||||||||
During the nine-month periods ended September 30, 2013 and 2012, realized gains and losses on the sale of investments were immaterial and there were no material impairments of our investments. | ||||||||||||||||||||||||
The fair value of the Financing Derivative (as defined in Note 7. Debt Facility) liability resulting from the debt facility we entered into during the first quarter of 2013 was determined using Level 3 inputs, or significant unobservable inputs. Refer to Note 7. Debt Facility for a detailed description and valuation approach. The following table provides the changes in the fair value of the Financial Derivative during the nine-month period ended September 30, 2013 (in thousands): | ||||||||||||||||||||||||
Financial Derivative | Amount | |||||||||||||||||||||||
Balance as of December 31, 2012 | $ | — | ||||||||||||||||||||||
Value at issuance | 967 | |||||||||||||||||||||||
Gain on change in fair value of Financing Derivative | -73 | |||||||||||||||||||||||
Balance as of September 30, 2013 | $ | 894 | ||||||||||||||||||||||
For the nine-month period ended September 30, 2013 there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and valuation techniques did not change compared to the prior quarter. | ||||||||||||||||||||||||
Financial assets and liabilities not measured at fair value on a recurring basis | ||||||||||||||||||||||||
The carrying amount of our accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses and other current liabilities, are determined to approximate fair value due to their short maturities. The carrying value of our facility financing obligation approximates fair value due to the time to maturity and prevailing market rates. | ||||||||||||||||||||||||
We determined the fair value of the Notes (as defined in Note 7. Debt Facility) from the debt facility we entered into during the first quarter of 2013 using Level 3 inputs, or significant unobservable inputs. The value of the Notes was determined by comparing the difference between the fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using a 20.8% weighted average market yield. Refer to Note 7. Debt Facility for additional details regarding the Notes. The estimated fair value and carrying value of the Notes are as follows (in thousands): | ||||||||||||||||||||||||

Agreement With Roche | ' |
NOTE 3. AGREEMENT WITH ROCHE | |
On September 24, 2013, we entered into a Development, Commercialization and License Agreement (the “Roche Agreement”) with F. Hoffman-La Roche Ltd (“Roche”), pursuant to which we: (i) will develop diagnostic products for clinical use including sequencing systems and consumables based on our proprietary SMRT technology; (ii) granted to Roche an exclusive right to commercialize, and an exclusive license to sell, the developed diagnostic products for clinical use; and (iii) will manufacture and supply certain products intended for clinical use as the exclusive supplier to Roche. We received a non-refundable up-front payment of $35.0 million and may receive up to an additional $40.0 million based upon the achievement of development milestones. The Roche Agreement has an initial term of thirteen years and provisions allowing Roche 5-year renewals. | |
The Roche Agreement contains multiple elements, and the deliverables under the Roche Agreement consist of intellectual property licenses, research and development services, and participation on the joint steering committee (as defined in the Roche Agreement) with Roche. These deliverables are non-contingent in nature. We evaluated whether there is standalone value for each of the non-contingent deliverables and allocated the upfront payment of $35.0 million to each unit of accounting based on our best estimates of selling prices pursuant to Accounting Standard Codification (ASC) Topic 605-25, Revenue Recognition — Multiple Element Arrangements (ASC 605-25). We consider the intellectual property licenses and research and development services to be a combined unit of accounting. The intellectual property licenses do not have standalone value since the diagnostic products to which the license relates are in a very early stage of development. In addition, we believe that the joint steering committee obligation has standalone value and thus, is a separate unit of accounting. | |
The amount allocated to the intellectual property licenses and research and development services will be recognized as revenue based on the proportional performance method over the expected development period, and the amount allocated to the deliverable of our participation on the joint steering committee will be recognized as revenue based on the proportional performance method over the term of the Roche Agreement, which represents the estimated obligation period of the joint steering committee. Revenue will be recognized on a straight-line basis over the delivery period to the extent that the pattern of performance is not expected to significantly differ from recognition using a proportional performance model. As of September 30, 2013, revenue relating to the $35.0 million upfront cash payment was deferred with $6.8 million and $28.2 million allocated to current and long-term deferred revenue, respectively. | |
Our process for determining estimates of selling prices involves management’s judgment. Our process considers multiple factors such as estimated headcount, annual research and development budget, estimated length of the research and development period and estimated transfer price on cost, which may vary over time, depending upon the circumstances, and relate to each deliverable. If the estimated obligation period of one or more deliverables should change, the future amortization of the revenue would also change. | |
In addition to the non-contingent deliverables above, the Roche Agreement includes contingent deliverables relating to the receipt of additional payments totaling $40.0 million upon the achievement of certain development milestones. Based on ASC Topic 605-28, Revenue Recognition — Milestone Method, we evaluate contingent milestones at inception of the agreement, and recognize consideration that is contingent upon the achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone is considered substantive in its entirety. Milestones are considered substantive if the consideration earned from the achievement of the milestone (i) is consistent with performance required to achieve the milestone or the increase in value to the delivered item, (ii) relates solely to past performance and (iii) is reasonable relative to all of the other deliverables and payments within the arrangement. The milestone payments of $40.0 million will be recognized as revenue in their entirety upon our achievement of each substantive milestone. | |

NOTE 6. CONTINGENCIES | |
We become subject to claims and assessments from time to time in the ordinary course of business. We accrue liabilities for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. | |
During October 2013 the Superior Court of the State of California, County of San Mateo granted final approval of a settlement of four class action lawsuits that had been consolidated as In re Pacific Biosciences of California Inc. S’holder Litig. In addition, the company has reached an agreement in principle to settle the claims of the single individual who opted out of the state court settlement. Upon its becoming final, the settlement of the state court action will have preclusive effect on claims previously asserted in the lawsuit filed in December 2011 in United States District Court for the Northern District of California, captioned Primo v. Pacific Biosciences of California, Inc., et al., Case No. 4:11-CV-06599. All amounts payable to the plaintiffs and plaintiffs’ counsel had been previously accrued; therefore, no additional amounts were expensed during the period. | |
Indemnification | |
Pursuant to Delaware law and agreements entered into with each of our directors and officers, we may have obligations, under certain circumstances, to hold harmless and indemnify each of our directors and officers against losses suffered or incurred by the indemnified party in connection with their service to the Company, and judgments, fines, settlements and expenses related to claims arising against such directors and officers to the fullest extent permitted under Delaware law, our bylaws and certificate of incorporation. We also enter and have entered into indemnification agreements with our directors and officers that may require us to indemnify them against liabilities that arise by reason of their status or service as directors or officers, except as prohibited by applicable law.

NOTE 7. DEBT FACILITY | ||
On February 5, 2013, we entered into a Facility Agreement (the “Facility Agreement”) with entities affiliated with Deerfield Management Company, L.P. (collectively, “Deerfield”), pursuant to which Deerfield agreed to provide $20.5 million in funding to us (the “Facility”). Under the terms of the Facility Agreement, we issued to Deerfield promissory notes in the aggregate principal amount of $20.5 million (the “Notes”). The Notes bear simple interest at a rate of 8.75% per annum, payable quarterly in arrears commencing on April 1, 2013 and on the first business day of each January, April, July and October thereafter. We received net proceeds of $20.0 million, representing $20.5 million of gross proceeds, less a $500,000 facility fee, before deducting other expenses of the transaction. | ||
The Facility Agreement has a maximum term of seven years from inception; however it provides for the early repayment of principal in the event we have net sales (as defined in the Facility Agreement) of less than $41.0 million for the twelve-month period from the beginning of the second calendar quarter of 2014 through the first calendar quarter of 2015 (the “Milestone”). If the Milestone is not achieved, at Deerfield’s option, one-third of the original principal balance of the Facility will become due, on each of the third, fourth and fifth anniversaries of the date of the Facility Agreement. | ||
From and after the date of the Facility Agreement, at the election of the holders of Notes representing a majority of the aggregate principal amount of the outstanding Notes, we shall apply 25% of the net proceeds from any financing that includes an equity component, including without limitation, the sale or issuance of our common stock, options, warrants or other securities convertible or exchangeable for shares of our common stock, to the payment of the Notes. This right is subject to certain exceptions set forth in the Facility Agreement, including that the right will not apply until we have issued 15.0 million shares (as adjusted for any stock split or reverse stock split) of our common stock or rights to acquire our capital stock following the date of the Facility Agreement. | ||
Deerfield has the option to require us to repay the Notes if we complete a Major Transaction (as defined in the Facility Agreement), including a change of control or a sale of all or substantially all of our assets. Additionally, the principal balance of the Facility may become immediately due and payable upon an Event of Default (as defined in the Facility Agreement), in which case Deerfield would have the right to require us to repay 100% of the principal amount of the loan, plus any accrued and unpaid interest thereon. The Facility Agreement does not provide for a prepayment of the Notes at our option. | ||
The Facility Agreement also contains various representations and warranties, and affirmative and negative covenants, customary for financings of this type, including restrictions on the ability of the Company and its subsidiaries to incur additional indebtedness or liens on its assets, except as permitted under the Facility Agreement. In addition, we are required to maintain consolidated cash and cash equivalents on the last day of each calendar quarter of not less than $2.0 million. As security for our repayment of our obligations under the Facility Agreement, we granted to Deerfield a security interest in substantially all of our property and interests in property. | ||
Financing Derivative | ||
A number of features embedded in the Notes to the Facility Agreement required accounting for as a derivative, including the indemnification of certain withholding taxes and the acceleration of debt upon (a) a qualified financing, (b) an Event of Default, (c) a Major Transaction, and (d) the exercise of the Warrant via offset to debt principal. These features represent a single derivative (the “Financing Derivative”) that was bifurcated from the debt instrument and accounted for as a liability at fair value, with changes in fair value between reporting periods recorded in other income (expense), net. The fair value of the Financing Derivative as of February 5, 2013 and September 30, 2013, was $1.0 million and $0.9 million, respectively. | ||
The value of the Financing Derivative as of February 5, 2013 and September 30, 2013 was determined by comparing the difference between the fair value of the Notes with and without the Financing Derivative by calculating the respective present values from future cash flows using a 20.8% weighted average market yield. | ||
Warrants | ||
In connection with the execution of the Facility Agreement, on February 5, 2013, we issued to Deerfield warrants to purchase an aggregate of 5,500,000 shares of common stock immediately exercisable at an exercise price per share initially equal to $2.63 (the “Warrants”). The number of shares of common stock into which the Warrants are exercisable and the exercise price will be adjusted to reflect any stock splits, payment of stock dividends, recapitalizations, reclassifications or other similar adjustments in the number of outstanding shares of common stock. The exercise price may also be adjusted to reflect certain dividends or other distributions, including distributions of stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or similar transaction. | ||
The Warrants are classified within additional paid-in capital and reported at their grant date fair value on February 5, 2013 of $6.4 million. We estimated the fair value of the Warrants using the Black-Scholes option pricing model using the following assumptions: | ||
Expected term | 7 years | |
Expected volatility | 50% | |
Risk-free interest rate | 1.4% | |
Dividend yield | — | |
Notes | ||
The Notes and Warrants were initially recorded at a value of $14.1 million and $6.4 million, respectively, based upon the relative fair value allocation of the $20.5 million of proceeds. Additionally, facility fees and other issuance costs were allocated based on the relative fair value of the Facility and the Warrants. The amount allocated to the Notes was then reduced by the $1.0 million fair value of the Financing Derivative, such that the Financing Derivative was recorded at its absolute fair value. As a result, the carrying value of the Notes at the inception of the debt was $12.8 million, resulting in an original issue discount of $7.7 million. The discount is being accreted to the $20.5 million face value of the Notes over the expected maturity period of seven years using the effective interest method, with an effective interest rate of 20.6%. | ||

Stock Offering | |
During April 2012, we filed a shelf registration statement on Form S-3 with the SEC pursuant to which we may, from time to time, sell up to an aggregate of $150.0 million of our common stock, warrants or debt securities. On May 1, 2012, the registration statement was declared effective by the SEC. On October 5, 2012, we entered into a Controlled Equity Offering Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co. (“Cantor”), pursuant to which we may offer and sell, from time to time, through Cantor, shares of our common stock having an aggregate offering price of up to $30.0 million through an “at-the-market” offering. We are not obligated to make any sales of shares under the Sales Agreement. We pay Cantor a commission equal to 3.0% of the gross proceeds from the sale of shares of our common stock under the Sales Agreement and reimburse up to $50,000 of legal expenses incurred by Cantor. During the quarter ended September 30, 2013, no shares were sold through our “at-the-market” offering. As of September 30, 2013, we have sold a total of 8.3 million shares of our common stock at an average price of $2.51 through our “at-the-market” offering. | |

As of September 30, 2013, we had three active equity compensation plans, the 2010 Equity Incentive Plan, or 2010 Plan, the 2010 Outside Director Equity Incentive Plan, or 2010 Director Plan, and the 2010 Employee Stock Purchase Plan, or “ESPP”. | ||||||||||||
As of September 30, 2013, no shares of our common stock remain available for issuance under our ESPP. The Employee Stock Purchase Plan provides for an annual increase to the shares available for issuance at the beginning of each calendar year equal to two percent of the common shares then outstanding. Our ESPP permits eligible employees to purchase common stock at a discount through payroll deductions during defined offering periods. Each offering period generally consists of four purchase periods, each purchase period being six months. The price at which the stock is purchased is equal to the lower of 85% of the fair market value of the common stock at the beginning of an offering period or at the end of a purchase period. Shares issued under the ESPP totaled 1,519,366 and 832,878 shares during the nine-month periods ended September 30, 2013 and 2012, respectively. We estimate the value of the employee stock purchase rights on the grant date using the Black-Scholes option pricing model. | ||||||||||||

Basis of Presentation | ||||||||||||||||||||||||
In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements (“financial statements”) of Pacific Biosciences of California, Inc. and its wholly-owned subsidiaries have been prepared on a consistent basis with the December 31, 2012 audited Consolidated Financial Statements and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. Certain prior year amounts in the financial statements and notes thereto have been reclassified to conform to the current year’s presentation. The financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and, therefore, omit certain information and footnote disclosures necessary to present the statements in accordance with U.S. generally accepted accounting principles (“GAAP”). These financial statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, which was filed with the SEC on March 15, 2013. The results of operations for the first nine months of fiscal 2013 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods. | ||||||||||||||||||||||||

Use of Estimates | ||||||||||||||||||||||||
The preparation of financial statements in conformity with GAAP requires us 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 revenue and expense during the reporting periods. Our estimates include, but are not limited to, useful lives assigned to long-lived assets, assumptions used to compute stock-based compensation expense and valuing warrants, value the financing derivative and long-term notes, value and recognize revenue elements, determine delivery periods for revenue recognition, and to compute provisions for income taxes, inventory, and contingencies. Actual results could differ from our estimates, and such differences could be material to our financial position and results of operations. | ||||||||||||||||||||||||

During the nine-month periods ended September 30, 2013 and 2012, realized gains and losses on the sale of investments were immaterial and there were no material impairments of our investments. | ||||||||||||||||||||||||
The fair value of the Financing Derivative (as defined in Note 7.

Based on ASC Topic 605-28, Revenue Recognition — Milestone Method, we evaluate contingent milestones at inception of the agreement, and recognize consideration that is contingent upon the achievement of a milestone in its entirety as revenue in the period in which the milestone is achieved only if the milestone is considered substantive in its entirety. Milestones are considered substantive if the consideration earned from the achievement of the milestone (i) is consistent with performance required to achieve the milestone or the increase in value to the delivered item, (ii) relates solely to past performance and (iii) is reasonable relative to all of the other deliverables and payments within the arrangement. The milestone payments of $40.0 million will be recognized as revenue in their entirety upon our achievement of each substantive milestone. | |
