NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
We record uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (i) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (ii) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.
On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted in the U.S. The TCJA represents sweeping changes in U.S. tax law. Under ASC 740, the effects of changes in tax rates and tax laws on deferred tax balances are recognized in the period in which the new legislation is enacted. The total effect of tax law changes on deferred tax balances is recorded as a component of income tax expense.
In response to the TCJA, the Staff of the U.S. Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 118 (“SAB 118”) to provide guidance to registrants in applying ASC 740 in connection with the TCJA. SAB 118 provides that, in the period of enactment, the income tax effects of the TCJA may be reported as a provisional amount based on a reasonable estimate (to the extent a reasonable estimate can be determined), which would be subject to adjustment during a measurement period. The measurement period begins in the reporting period of the TCJA’s enactment and ends when a registrant has obtained, prepared, and analyzed the information that was needed in order to complete the accounting requirements under ASC 740. SAB 118 also describes supplemental disclosures that should accompany the provisional amounts. As of December 31, 2017, we applied the guidance in SAB 118 to account for the financial accounting impacts of the TCJA and have provided the applicable supplemental disclosures in “Note 13. Income Taxes.”
i) Net Income/(Loss) Per Share
We compute net income/(loss) per share in accordance with ASC 260 - Earnings Per Share. Basic net income/(loss) per share is computed by dividing net income/(loss) by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by giving effect to all potential dilutive common stock equivalents, including stock options, RSUs, PSOs and PSUs, using the treasury stock method.
Certain stock options, which are priced higher than the market price of our shares as of September 30, 2018 would be anti-dilutive and therefore have been excluded from the weighted average shares used in computing diluted net income per share. These options could become dilutive in future periods. Similarly, certain recently granted RSUs are also excluded using the treasury stock method as their impact would be anti-dilutive. The dilutive effect of weighted average shares outstanding excludes approximately 0.1 million and 0.5 million shares for the three and nine month periods ended September 30, 2018, respectively, as their effect would have been anti-dilutive on our net income per share.
j) Segment Information
ASC 280 - Segment Reporting, establishes standards for reporting information regarding operating segments in annual financial statements. Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance.
We report our business under two segments: Healthcare and Research. The Healthcare segment is focused on remote cardiac monitoring to identify cardiac arrhythmias or heart rhythm disorders. We offer
