The 2017 cybersecurity incident is expected to continue to negatively impact revenue, principally in our USIS and Global Consumer Solutions businesses.
We have incurred, in 2018, and will continue to incur, in 2019, legal, consulting and other costs related to the analysis and response to the 2017 cybersecurity incident.
Additionally, in 2018 and beyond, we have incurred and will continue to incur increased costs and capital expenditures related to our technology transformation, which includes costs for enhanced data security.
In 2018 and beyond, we had and will continue to have increases in the ongoing runrate of technology and security spending.
We also expect to continue to incur increased expenses for insurance, finance, compliance activities, and to meet increased legal and regulatory requirements.
The ultimate amount of these increases is expected to be significant.
As a result of the 2017 cybersecurity incident, we are subject to a significant number of proceedings and investigations as described in “Item 3.
Legal Proceedings” in this Form 10-K.
While we believe it is reasonably possible that we will incur losses associated with these proceedings and investigations, it is not possible to estimate the amount of loss or range of possible loss that might result from adverse judgments, settlements, penalties or other resolution of the proceedings and investigations based on the various stages of these proceedings and investigations, that alleged damages have not been specified or are uncertain, the uncertainty as to the certification of a class or classes and the size of any certified class, as applicable, and the lack of resolution on significant factual and legal issues.
The Company will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable.
The Company believes that the ultimate amount paid on these actions, claims and investigations could be material to the Company’s consolidated financial condition, results of operations, or cash flows in future periods and may reduce available resources to invest in technology and innovation.38 RESULTS OF OPERATIONS — TWELVE MONTHS ENDED DECEMBER 31, 2018, 2017 AND 2016 Consolidated Financial Results Operating Revenue

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS We record tax benefits for positions that we believe are more likely than not of being sustained under audit examinations.
We assess the potential outcome of such examinations to determine the adequacy of our income tax accruals.
We recognize interest and penalties accrued related to unrecognized tax benefits in the provision for income taxes on our Consolidated Statements of Income.
We adjust our income tax provision during the period in which we determine that the actual results of the examinations may differ from our estimates or when statutory terms expire.
Changes in tax laws and rates are reflected in our income tax provision in the period in which they are enacted.
??
Earnings Per Share.
Our basic earnings per share, or EPS, is calculated as net income divided by the weightedaverage number of common shares outstanding during the reporting period.
Diluted EPS is calculated to reflect the potential dilution that would occur if stock options or other contracts to issue common stock were exercised and resulted in additional common shares outstanding.
The net income amounts used in both our basic and diluted EPS calculations are the same.
A reconciliation of the weighted-average outstanding shares used in the two calculations is as follows:
## Table 1 ##
For the twelve months ended December 31, 2018, 2017 and 2016, 0.7 million, 0.3 million and 0.1 million stock options, respectively, were anti-dilutive and therefore excluded from this calculation.
Cash Equivalents.
We consider all highly-liquid investments with an original maturity of three months or less to be cash equivalents.
Trade Accounts Receivable and Allowance for Doubtful Accounts. ?
?Accounts receivable are stated at cost.
Significant payment terms for customers are identified in the contract.
We do not recognize interest income on our trade accounts receivable.
Additionally, we generally do not require collateral from our customers related to our trade accounts receivable.
The allowance for doubtful accounts for estimated losses on trade accounts receivable is based on historical write-off experience, an analysis of the aging of outstanding receivables, customer payment patterns and the establishment of specific reserves for customers in an adverse financial condition.
We reassess the adequacy of the allowance for doubtful accounts each reporting period.
Increases to the allowance for doubtful accounts are recorded as bad debt expense, which are included in selling, general and administrative expenses on the accompanying Consolidated Statements of Income.
Bad debt expense was $5.6 million, $5.0 million and $2.2 million during the twelve months ended December 31, 2018, 2017, and 2016, respectively.
??
Other Current Assets.
Other current assets on our Consolidated Balance Sheets include certain current tax receivable accounts.
As of December 31, 2018 and 2017 these assets were approximately, $69.4 million and $54.2 million, respectively.
Other current assets also includes an insurance receivable for costs incurred to date related to the 2017 cybersecurity incident that are reimbursable and probable of recovery under our insurance coverage.
As of December 31, 2018 the Company had no receivable outstanding.
As of December 31, 2017, the Company has recorded a receivable of $35.0 million.
For additional information, see Note 6.
Other current assets also include amounts in specifically designated accounts that hold the funds that are due to customers from our debt collection and recovery management services.
As of December 31, 2018 and 2017 these assets were approximately $31.0 million and $21.4 million, respectively, with fully offsetting balances in other current liabilities.
These amounts are restricted as to their current use and will be released according to the specific customer agreements.
Long-Lived Assets.
Property and equipment are stated at cost less accumulated depreciation and amortization.
The cost of additions is capitalized.
Property and equipment are depreciated on a straight-line basis over the assets’ estimated useful lives, which are generally three to ten years for data processing equipment and capitalized internal-use software and systems costs.
Leasehold improvements are depreciated over the shorter of their estimated useful lives or lease terms that are reasonably assured.
Buildings are depreciated over a forty-year period.
Other fixed assets are depreciated over three to seven years.
Upon sale or retirement of an asset, the related costs and accumulated depreciation are removed from the accounts and any gain or loss is recognized and included in income from operations on the Consolidated Statements of Income, with the classification of any gain or loss dependent on the characteristics of the asset sold or retired.
Stock Performance Graph The following graph provides a comparison of five year cumulative total stockholder returns of Teleflex common stock, the Standard & Poor’s (S&P) 500 Stock Index and the S&P 500 Healthcare Equipment & Supply Index.
The annual changes for the five-year period shown on the graph are based on the assumption that $100 had been invested in Teleflex common stock and each index on December 31, 2009 and that all dividends were reinvested.
