CDT Defined Benefit Plan

CDT sponsors an unfunded defined benefit pension plan covering substantially all CDT employees (CDT pension plan) which provides for old age, disability and survivors’ benefits. Benefits under the CDT pension plan are generally based on age at retirement, years of service and the employee’s annual earnings. The net periodic cost of this pension plan is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and estimated service costs.

The following are the details of the change in the benefit obligation for the CDT pension plan for the periods indicated:



	As of December 31, 2013			As of June 30, 2013
Benefit obligation—beginning of period	$	23,871		$	21,461
Service cost	228			457
Interest cost	436			888
Benefits paid	(251		)	(466		)
Actuarial (gain) loss	(1,027		)	278
Foreign exchange (gain) loss	1,241			1,253
Benefit obligation—end of period	24,498			23,871
Less: Current portion	(601		)	(535		)
Non current portion of benefit obligation	$	23,897		$	23,336

The following are the details of net pension expense for the CDT pension plan for the periods indicated:



	Three Months Ended December 31,				Six Months Ended December 31,
	2013		2012		2013		2012
Pension expense:
Service cost	$	115	$	117	$	228	$	230
Interest cost	219		226		436		446
Amortization of actuarial gains and losses	69		71		138		139
Net pension expense	$	403	$	414	$	802	$	815

The CDT pension plan is an unfunded plan and therefore no contributions have been made since the inception of the plan. Actuarial gains and losses in excess of 10% of the greater of the projected benefit obligation or the market-related value of plan obligations are being amortized and recognized as a component of net periodic benefit costs over the average remaining service period of the plan's active employees. As of December 31, 2013 there is approximately $0.1 million in accumulated other comprehensive income related to the CDT pension plan that is expected to be recognized as a component of net periodic benefit costs over the remaining fiscal year.

In determining the fair value of the CDT pension plan benefit obligations as of December 31, 2013 and June 30, 2013, respectively, we used the following weighted-average key assumptions:



	As of December 31, 2013		As of June 30, 2013
Assumptions:
Salary increases	2.50	%	2.50	%
Pension increases	2.00	%	2.00	%
Discount rate	3.70	%	3.50	%
Employee fluctuation rate:
to age 30	1.00	%	1.00	%
to age 35	0.50	%	0.50	%
to age 40	—	%	—	%
to age 45	0.50	%	0.50	%
to age 50	0.50	%	0.50	%
from age 51	1.00	%	1.00	%

The Company's discount rate is based on AA-rated bonds, denominated in Euros, from German corporations.

Anticipated pension payments under the CDT pension plan for the fiscal years indicated below are as follows:



	Fiscal years ending June 30,
2014 (six months ended June 30)	$	301
2015	622
2016	690
2017	760
2018	815
2019 to 2023	5,976
Total	$	9,164

CDT Anniversary Plan

CDT’s long-term employee benefit obligations arise under CDT’s “anniversary plan”. The obligation is unfunded and is carried at its fair value.

IXOS Defined Benefit Plans

Included in our pension liability, as of December 31, 2013, is a net amount of $0.8 million (June 30, 2013—$0.8 million) that relates to two IXOS defined benefit pensions plans (IXOS pension plans) in connection with certain former members of the IXOS Board of Directors and certain IXOS employees, respectively. The net periodic pension cost with respect to the IXOS pension plans is determined using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate and the expected return on plan assets.
