Investments in Consolidated Variable Interest Entities GRAIL, Inc. In January 2016, the Company obtained a majority equity ownership interest in GRAIL, Inc. (GRAIL), a company formed with unrelated third party investors to pursue the development and commercialization of a blood test for asymptomatic cancer screening. The Company determined that GRAIL is a variable interest entity as the entity lacks sufficient equity to finance its activities without additional support. Additionally, the Company determined that it has (a) control of the entity’s Board of Directors, which has unilateral power over the activities that most significantly impact the economic performance of GRAIL and (b) the obligation to absorb losses of and the right to receive benefits from GRAIL that are potentially significant to GRAIL. As a result, the Company is deemed to be the primary beneficiary of GRAIL and is required to consolidate GRAIL. On a fully diluted basis, the Company holds a 52% equity ownership interest in GRAIL as of July 3, 2016 . During the three months ended April 3, 2016, GRAIL completed its Series A convertible preferred stock financing, raising $120.0 million , of which the Company invested $40.0 million . Additionally, the Company and GRAIL executed a long-term supply agreement in which the Company contributed certain perpetual licenses, employees, and discounted supply terms in exchange for 112.5 million shares of GRAIL’s Class B Common Stock. Such contributions are recorded at their historical basis as they remain within the control of the Company. The $80.0 million received by GRAIL from unrelated third party investors upon issuance of its Series A convertible preferred stock is classified as noncontrolling interests in stockholders’ equity on the Company’s consolidated balance sheet. During the three months ended July 3, 2016, GRAIL authorized for issuance 97.5 million shares of Series A-1 convertible preferred stock, all of which were issued to Illumina in exchange for 97.5 million shares of Illumina’s Class B Common Stock on June 23, 2016. As a result of the exchange, Illumina recorded a $9.5 million deemed dividend net of tax of $9.6 million through equity, which was eliminated in consolidation. Additionally, $1.6 million was added to net income attributable to Illumina stockholders for purposes of calculating Illumina’s consolidated earnings per share, which represents the deemed dividend, net of Illumina’s portion of the losses incurred by GRAIL’s common shareholders resulting from the exchange. For the three and six months ended July 3, 2016 , the Company absorbed 90% of GRAIL’s losses based upon its proportional ownership of GRAIL’s common stock. Beginning July 4, 2016, the Company will absorb approximately 50% of GRAIL’s losses based upon its proportional ownership of GRAIL’s common stock subsequent to the exchange. In accordance with GRAIL’s Equity Incentive Plan, the Company may be required to redeem certain vested stock awards in cash at the then approximate fair market value. The fair value of the redeemable noncontrolling interests is considered a Level 3 instrument. Such redemption right is exercisable at the option of the holder of the awards after February 28, 2021, provided that an initial public offering of GRAIL has not been completed. As the redemption provision is outside of the control of the Company, the redeemable noncontrolling interests in GRAIL are classified outside of stockholders’ equity on the accompanying condensed consolidated balance sheets. The balance of the redeemable noncontrolling interests is reported at the greater of its carrying value after receiving its allocation of GRAIL’s profits and losses or its estimated redemption value at each reporting date. The assets and liabilities of GRAIL other than cash and cash equivalents are not significant to the Company’s financial position as of July 3, 2016 and have an immaterial impact on the Company’s condensed consolidated statements of income and cash flows for the three and six months ended July 3, 2016 . Helix Holdings I, LLC In July 2015, the Company obtained a 50% voting equity ownership interest in Helix Holdings I, LLC (Helix), a limited liability company formed with unrelated third party investors to pursue the development and commercialization of a marketplace for consumer genomics. The Company determined that Helix is a variable interest entity as the holder of the at-risk equity investments as a group lack the power to direct the activities of Helix that most significantly impact Helix’s economic performance. Additionally, the Company determined that it has (a) unilateral power over one of the activities that most significantly impacts the economic performance of Helix through its contractual arrangements and no one individual party has unilateral power over the remaining significant activities of Helix and (b) the obligation to absorb losses of and the right to receive benefits from Helix that are potentially significant to Helix. As a result, the Company is deemed to be the primary beneficiary of Helix and is required to consolidate Helix. As contractually committed, the Company contributed certain perpetual licenses, instruments, intangibles, initial laboratory setup, and discounted supply terms in exchange for voting equity interests in Helix. Such contributions are recorded at their historical basis as they remain within the control of the Company. Helix is financed through cash contributions made by the third party investors in exchange for voting equity interests in Helix. Certain noncontrolling Helix investors may require the Company to redeem all noncontrolling interests in cash at the then approximate fair market value. The fair value of the redeemable noncontrolling interests is considered a Level 3 instrument. Such redemption right is exercisable at the option of certain noncontrolling interest holders after January 1, 2021, provided that a bona fide pursuit of the sale of Helix has occurred and an initial public offering of Helix has not been completed. As the contingent redemption is outside of the control of Illumina, the redeemable noncontrolling interests in Helix are classified outside of stockholders’ equity on the consolidated balance sheet. The balance of the redeemable noncontrolling interests is reported at the greater of its carrying value after receiving its allocation of Helix’s profits and losses or its estimated redemption value at each reporting date. As of July 3, 2016 , the noncontrolling shareholders and Illumina each held 50% of Helix’s outstanding voting equity interests. The assets and liabilities of Helix are not significant to the Company’s financial position as of July 3, 2016 . Helix has an immaterial impact on the Company’s condensed consolidated statements of income and cash flows for the three and six months ended July 3, 2016 . As of July 3, 2016 , the accompanying condensed consolidated balance sheet includes $123.6 million of cash and cash equivalents attributable to GRAIL and Helix that will be used to settle their respective obligations and will not be available to settle obligations of the Company. Redeemable Noncontrolling Interests The activity of the redeemable noncontrolling interests during the six months ended July 3, 2016 is as follows (in thousands): Redeemable Noncontrolling Interests Balance as of January 3, 2016 $ 32,546 Vesting of redeemable equity awards 1,031 Net loss attributable to noncontrolling interests (5,270 ) Adjustment up to the redemption value 5,426 Balance as of July 3, 2016 $ 33,733 |
