Bio-Rad Reports Fourth-Quarter and Full-Year 2018 Financial Results

. Although these events are reflected in our GAAP financials, these unique transactions may limit the comparability of our on-going operations with prior and future periods.

Significant litigation charges or benefits and legal costs: we may incur charges or benefits as well as legal costs in connection with litigation and other contingencies unrelated to our core operations. We exclude these charges or benefits, when significant, as well as legal costs associated with significant legal matters, because we do not believe they are reflective of on-going business and operating results.

Income tax expense: we estimate the tax effect of the excluded items identified above to determine a non-GAAP annual effective tax rate applied to the pretax amount in order to calculate the non-GAAP provision for income taxes. We also adjust for items for which the nature and/or tax jurisdiction requires the application of a specific tax rate or treatment.

From time to time in the future, there may be other items excluded if we believe that doing so is consistent with the goal of providing useful information to investors and management.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP in the United States. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.

Reconciliation of GAAP financial measures to non-GAAP financial measures

(In thousands, except per share data)

(Unaudited)

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including non-GAAP net income and non-GAAP diluted income per share (non-GAAP EPS), which exclude amortization of acquisition-related intangible assets; certain acquisition-related expenses and benefits; restructuring charges; asset impairment charges; valuation changes of equity owned investments; gains and losses on equity-method investments; and significant legal-related charges or benefits and associated legal costs. Non-GAAP net income and non-GAAP EPS also exclude certain other gains and losses that are either isolated or cannot be expected to occur again with any predictability, tax provisions/benefits related to the previous items, and significant discrete tax events. We exclude the above items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods.

We utilize a number of different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures to be helpful in assessing the performance of the ongoing operation of our business. We believe that disclosing non-GAAP financial measures provides useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. We also believe that disclosing non-GAAP financial measures provides useful information to investors and others in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies.
