Basic net income per ordinary share has been computed by dividing
net income available to ordinary shareholders by the weighted
average number of ordinary shares outstanding during the
period. Diluted net income per ordinary share is computed by
adjusting the weighted average number of ordinary shares
outstanding during the period for all potentially dilutive ordinary
shares outstanding during the period and adjusting net income for
any changes in income or loss that would result from the conversion
of such potential ordinary shares. There is no difference in
net income used for basic and diluted net income per ordinary
share.

Share Options
On July 21, 2008 the Company adopted the Employee Share Option Plan
2008 (the “2008 Employee Plan”) pursuant to which the
Compensation and Organization Committee of the Company’s
Board of Directors may grant options to any employee, or any
Director holding a salaried office or employment with the Company
or a Subsidiary for the purchase of ordinary shares. On the
same date, the Company also adopted the Consultants Share Option
Plan 2008 (the “2008 Consultants Plan”), pursuant to
which the Compensation and Organization Committee of the
Company’s Board of Directors may grant options to any
consultant, adviser or non-executive Director retained by the
Company or any Subsidiary for the purchase of ordinary
shares.
On February 14, 2017 both the 2008 Employee Plan and the 2008
Consultants Plan (together the “2008 Option Plans”)
were amended and restated in order to increase the number of
options that can be issued under the 2008 Consultants Plan
from 400,000 to 1 million and to extend the date for options to be
granted under the 2008 Option Plans.
Each option granted under the 2008 Option Plans will be an employee
stock option, or Non-qualifying Stock Options (‘NSO’),
as described in Section 422 or 423 of the Internal Revenue
Code. Each grant of an option under the 2008 Options Plans
will be evidenced by a Stock Option Agreement between the optionee
and the Company. The exercise price will be specified in each
Stock Option Agreement, however option prices will not be less than
100% of the fair market value of an ordinary share on the date the
option is granted.
An aggregate of 6 million ordinary shares have been reserved under
the 2008 Employee Plan, as reduced by any shares issued or to be
issued pursuant to options granted under the 2008 Consultants Plan,
under which a limit of 1 million shares applies. Further, the
maximum number of ordinary shares with respect to which options may
be granted under the 2008 Employee Option Plan, during any calendar
year to any employee shall be 400,000 ordinary shares. There
is no individual limit under the 2008 Consultants Plan. No
options may be granted under the 2008 Option Plans after February
14, 2027.
On January 17, 2003 the Company adopted the Share Option Plan 2003
(the “2003 Share Option Plan”) pursuant to which the
Compensation and Organization Committee of the Board could grant
options to officers and other employees of the Company or its
subsidiaries for the purchase of ordinary shares. An
aggregate of 6 million ordinary shares were reserved under the 2003
Share Option Plan; and, in no event could the number of ordinary
shares issued pursuant to options awarded under this plan exceed
10% of the outstanding shares, as defined in the 2003 Share Option
Plan, at the time of the grant, unless the Board expressly
determined otherwise. Further, the maximum number of ordinary
shares with respect to which options could be granted under the
2003 Share Option Plan during any calendar year to any employee was
400,000 ordinary shares. The 2003 Share Option Plan expired
on January 17, 2013. No new options may be granted under this
plan.
Share option awards are granted with an exercise price equal to the
market price of the Company’s shares at date of grant. Share
options typically vest over a period of five years from date of
grant and expire eight years from date of grant. The maximum
contractual term of options outstanding at March 31, 2017 is eight
years.
The following table summarizes option activity for the three months
ended March 31, 2017:
The Company has outstanding options with fair values ranging from
$6.72 to $24.49 per option or a weighted average fair value of
$11.12 per option. The Company issues ordinary shares for all
options exercised. The total amount of fully vested share
options which remained outstanding at March 31, 2017, was
682,269. Fully vested share options at March 31, 2017, have
an average remaining contractual term of 3.79 years, an average
exercise price of $36.53 and a total intrinsic value of $29.5
million. The total intrinsic value of options exercised
during the three months ended March 31, 2017 was $7.4 million
(March 31, 2016: $2.2 million).
The following table summarizes the movement in non-vested share
options for the three months ended March 31, 2017:
Fair value of Stock Options Assumptions
The weighted average fair value of options granted during the three
months ended March 31, 2017 and March 31, 2016 was calculated using
the Black-Scholes option pricing model. The weighted average
fair values and assumptions used were as follows:
Expected volatility is based on the historical volatility of our
common stock over a period equal to the expected term of the
options; the expected life represents the weighted average period
of time that options granted are expected to be outstanding given
consideration to vesting schedules and our historical experience of
past vesting and termination patterns. The risk-free rate is based
on the U.S. government zero-coupon bonds yield curve in effect at
time of the grant for periods corresponding with the expected life
of the option.
Restricted Share Units and Performance Share Units
On July 21, 2008 the Company adopted the 2008 Employees Restricted
Share Unit Plan (the “2008 RSU Plan”) pursuant to which
the Compensation and Organization Committee of the Company’s
Board of Directors may select any employee, or any Director holding
a salaried office or employment with the Company, or a Subsidiary
to receive an award under the plan. An aggregate of 1.0 million
ordinary shares have been reserved for issuance under the 2008 RSU
Plan.
On April 23, 2013 the Company adopted the 2013 Employees Restricted
Share Unit (“RSU”) and Performance Share Unit
(“PSU”) Plan (the “2013 RSU Plan”) pursuant
to which the Compensation and Organization Committee of the
Company’s Board of Directors may select any employee, or any
Director holding a salaried office or employment with the Company,
or a Subsidiary to receive an award under the plan. On May
11, 2015 the 2013 RSU Plan was amended and restated in order to
increase the number of shares that can be issued under the RSU Plan
by 2.5 million shares. Accordingly, an aggregate of 4.1
million ordinary shares have been reserved for issuance under the
2013 RSU Plan. The shares are awarded at par value and vest
over a service period. Awards under the 2013 RSU Plan may be
settled in cash or shares at the option of the Company.
The Company has awarded RSUs and PSUs to certain key individuals of
the Group. The following table summarizes RSU and PSU
activity for the three months ended March 31, 2017:
The fair value of RSUs vested for the three months ended March 31,

| Business Segment Information |
9. Business Segment Information
The Company determines and presents operating segments based on the
information that is internally provided to the chief operating
decision maker, together the (‘CODM’) in accordance
with FASB ASC 280-10
Disclosures about Segments of an Enterprises and Related
Information. The Chief Executive Officer, Chief
Financial Officer and Chief Operating Officer, were together
considered the Company’s CODM in the period up to and
including March 1, 2017. On March 1, 2017, Mr Ciaran Murray
transitioned from his role as Chief Executive Officer to the role
of Executive Chairman of the Board of Directors and Dr. Steve
Cutler was appointed as Chief Executive Officer. As of, March
1, 2017, the Company determined that the CODM is comprised of the
Chief Executive Officer and the Chief Financial Officer.
The Company determines and presents operating segments based on the
information that is provided to the CODM. The Company has
determined that we operate in one single business segment which is
the provision of outsourced development services on a global basis
to the pharmaceutical, biotechnology and medical devices
industries. There have been no changes to the basis of
segmentation or the measurement basis for the segment results in
the period.
The Company is a contract research organization
(“CRO”), providing outsourced development services on a
global basis to the pharmaceutical, biotechnology and medical
device industries. It specializes in the strategic
development, management and analysis of programs that support all
stages of the clinical development process - from compound
selection to Phase I-IV clinical studies. The Company
has the expertise and capability to conduct clinical trials in most
major therapeutic areas on a global basis and has the operational
flexibility to provide development services on a stand-alone basis
or as part of an integrated “full service”
solution. The Company has expanded predominately through
internal growth together with a number of strategic acquisitions to
enhance its expertise and capabilities in certain areas of the
clinical development process.
The Company is generally awarded projects based upon responses to
requests for proposals received from companies in the
pharmaceutical, biotechnology and medical device industries or work
orders executed under our strategic partnership arrangements.
Contracts with customers are generally entered into centrally, in
most cases with ICON Clinical Research Limited (“ICON
Ireland”), the Company’s principal operating subsidiary
in Ireland. Revenues, which consist primarily of fees earned
under these contracts, are allocated to individual entities within
the Group, based on where the work is performed in accordance with
the Company’s global transfer pricing model.
ICON Ireland acts as the group entrepreneur under the
Company’s global transfer pricing model given its role in the
development and management of the group, it’s ownership of
key intellectual property and customer relationships, its key role
in the mitigation of risks faced by the group and its
responsibility for maintaining the Company’s global
network. ICON Ireland enters into the majority of the
Company’s customer contracts.
ICON Ireland remunerates other operating entities in the ICON Group
on the basis of a guaranteed cost plus mark up for the services
they perform in each of their local territories. The cost
plus mark up for each ICON entity is established to ensure that
each of ICON Ireland and the ICON entities that are involved in the
conduct of services for customers, earn an appropriate arms-length
return having regard to the assets owned, risks borne, and
functions performed by each entity from these intercompany
transactions. The cost plus mark-up policy is reviewed
annually to ensure that it is market appropriate.
The geographic split of revenue disclosed for each region outside
Ireland is the cost plus revenue attributable to these
entities. The residual revenues of the Group, once each ICON
entity has been paid its respective intercompany service fee,
generally fall to be retained by ICON Ireland. As such
revenues and income from operations in Ireland are a function of
this global transfer pricing model and comprise net revenues of the
Group after deducting the cost plus revenues attributable to the
activities performed outside Ireland.
The Company's areas of operation outside of Ireland include the
United States, United Kingdom, Belgium, France, Germany, Italy,
Spain, The Netherlands, Sweden, Turkey, Poland, Czech Republic,
Latvia, Russia, Ukraine, Hungary, Israel, Romania, Switzerland,
Canada, Mexico, Brazil, Colombia, Argentina, Chile, Peru, India,
China, South Korea, Japan, Thailand, Taiwan, Singapore, The
Philippines, Australia, New Zealand, and South Africa.
The geographical distribution of the Company’s segment
measures as at March 31, 2017 and December 31, 2016 and for the
three months ended March 31, 2017 and March 31, 2016 is as
