Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of SEC Regulation S-X. Accordingly, they should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018, filed with the SEC on March 4, 2019 (the “Form 10-K”). The accompanying unaudited condensed consolidated financial statements include the accounts of La Jolla Pharmaceutical Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The unaudited condensed consolidated financial statements contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to present fairly the condensed consolidated balance sheet as of June 30, 2019, the condensed consolidated statements of operations for the three and six months ended June 30, 2019, the condensed consolidated statement of shareholder’s (deficit) equity for the three and six months ended June 30, 2019 and the condensed consolidated statement of cash flows for the six months ended June 30, 2019.

The preparation of the Company’s unaudited condensed consolidated financial statements requires management to make estimates and assumptions that impact the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities in the Company’s unaudited condensed consolidated financial statements and the accompanying notes. Actual results may differ materially from these estimates. Certain amounts previously reported in the financial statements have been reclassified to conform to the current year presentation. Such reclassifications did not affect net loss, shareholders’ equity or cash flows. The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year or any future interim periods. The accompanying condensed consolidated balance sheet as of December 31, 2018 has been derived from the audited consolidated balance sheet as of December 31, 2018 contained in the Form 10-K.

Summary of Significant Accounting Policies

During the six months ended June 30, 2019, there have been no changes to the Company’s significant accounting policies as described in the Form 10-K, except as described below.

Leases

At lease commencement, the Company records a lease liability based on the present value of lease payments over the expected lease term. The Company calculates the present value of lease payments using the discount rate implicit in the lease, unless that rate cannot be readily determined. In that case, the Company uses its incremental borrowing rate, which is the rate of interest that the Company would have to pay to borrow on a collateralized basis an amount equal to the lease payments over the expected lease term. The Company records a corresponding right-of-use lease asset based on the lease liability, adjusted for any lease incentives received and any initial direct costs paid to the lessor prior to the lease commencement date.

After lease commencement, the Company measures its leases as follows: (i) the lease liability based on the present value of the remaining lease payments using the discount rate determined at lease commencement; and (ii) the right-of-use lease asset based on the remeasured lease liability, adjusted for any unamortized lease incentives received, any unamortized initial direct costs and the cumulative difference between rent expense and amounts paid under the lease agreement. Any lease incentives received and any initial direct costs are amortized on a straight-line basis over the expected lease term. Rent expense is recorded on a straight-line basis over the expected lease term.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash. The Company maintains its cash in checking and savings accounts at federally insured financial institutions in excess of federally insured limits.

The Company’s products are distributed in the U.S. through distributors and select wholesalers (collectively, customers) that resell its products to hospitals, the end users. The following table includes the percentage of net product sales and accounts receivable balances for the Company’s four major customers, each of which comprised 10% or more of its net product sales:



	Net Product Sales				Accounts Receivable
	Three Months Ended June 30, 2019		Six Months Ended June 30, 2019		As of June 30, 2019
Customer A	32	%	32	%	31	%
Customer B	28	%	30	%	10	%
Customer C	25	%	28	%	24	%
Customer D	15	%	10	%	35	%
Total	100	%	100	%	100	%

Net Loss per Share

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration of potential common shares. Diluted net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding plus potential common shares. Convertible preferred stock, stock options and warrants are considered potential common shares and are included in the calculation of diluted net loss per share using the treasury stock method when their effect is dilutive. Potential common shares are excluded from the calculation of diluted net loss per share when their effect is anti-dilutive. As of June 30, 2019 and 2018, there were 14.0 million shares and 14.2 million shares, respectively, of potential common shares, which were excluded from the calculation of diluted net loss per share because their effect was anti-dilutive.

Recent Accounting Pronouncements

In June 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2018-07, Stock Compensation (Topic 718): Improvements to Nonemployee Share-based Payment Accounting (“ASU 2018-07”). The standard expands the scope of Accounting Standards Codification (“ASC”) Topic 718 to include share-based payment awards granted to nonemployees in exchange for goods and services. ASU 2018-07 is effective for annual and interim reporting periods beginning after December 15, 2018.

In the first quarter 2019, the Company adopted ASU 2018-07. Prior to the adoption of ASU 2018-07, share-based payments awards granted to nonemployees were measured at fair value on their grant date, subject to periodic remeasurement, and share-based compensation expense was recognized on a straight-line basis over their vesting terms. After the adoption of ASU 2018-07, the fair value of share-based payment awards granted to nonemployees is not required to be remeasured periodically and share-based compensation expense will continue to be recorded on a straight-line basis over their vesting period, consistent with share-based payment awards granted to employees. As a result of the adoption of ASU 2018-07, the Company remeasured all of its outstanding nonemployee share-based payment awards at fair value and recognized a cumulative-effect adjustment of $0.2 million to accumulated deficit as of January 1, 2019.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). This guidance requires lessees to recognize operating leases with a term greater than one year on the balance sheet as a right-of-use asset and corresponding lease liability. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018. Although ASU 2016-02 is required to be adopted at the earliest period presented using a modified retrospective approach, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”), which allows for an alternative transition method of adoption by recognizing a cumulative-effect adjustment, if any, to the opening balance of retained earnings in the period of adoption.

The Company adopted ASU 2016-02 on January 1, 2019 utilizing the alternative transition method allowed under ASU 2018-11. As a result, the Company recorded a lease liability and right-of-use lease asset of $31.8 million and $16.8 million, respectively, on its balance sheet as of January 1, 2019. The lease liability represents the present value of the remaining lease payments of the Company’s corporate headquarters lease (see Note 4), discounted using the Company’s incremental borrowing rate as of January 1, 2019. The corresponding right-of-use lease asset is recorded based on the lease liability, adjusted for the unamortized lease incentives received and the cumulative difference between rent expense and amounts paid under the corporate headquarters lease. The adoption of ASU 2016-02 did not have a material impact on either the statement of operations or statement of cash flows for the three and six months ended June 30, 2019.
