The new revenue recognition standard (ASU No. 2014-09) ‘Revenue from Contracts with Customers’ was effective for ICON plc from January 1, 2018. ICON has elected to adopt the new standard under the cumulative effect transition method. Under this transition method, the new standard is applied from January 1, 2018 without restatement of comparative period amounts. The cumulative effect of initially applying the new standard is reflected as an adjustment to opening equity at the date of application. Results for the three and nine months ended September 2017 are therefore presented under the previous revenue recognition accounting principles.

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), this press release contains certain non-GAAP financial measures, including non-GAAP operating and net income and non-GAAP diluted earnings per share. While non-GAAP financial measures are not superior to or a substitute for the comparable GAAP measures, ICON believes certain non-GAAP information is useful to investors for historical comparison purposes.

ICON will hold its third quarter conference call tomorrow, October 25th, 2018 at 09:00 EDT [14:00 Ireland & UK]. This call and linked slide presentation can be accessed live from our website at http://investor.iconplc.com. A recording will also be available on the website for 90 days following the call.
