7.	RETIREMENT PLANS

Defined Contribution Plans

We have a qualified profit sharing plan subject to United States Internal Revenue Code Section 401(k) for eligible U.S. employees. We make employer contributions under this qualified profit sharing plan that are included in the accompanying Consolidated Statements of Comprehensive Income. For the years ended December 31, 2016, 2015 and 2014 our employer contributions were $23.4 million, $19.3 million and $17.1 million, respectively. The related trust assets of this plan are managed by trustees and are excluded from the accompanying Consolidated Financial Statements.

We maintain several defined contribution retirement plans for eligible non-U.S. employees. Our contributions to these plans were approximately $27.2 million, $29.0 million and $27.4 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Defined Benefit Plans

We maintain four defined benefit pension plans in the United Kingdom, Ireland and the Netherlands to provide retirement benefits to eligible employees. It is our policy to fund at least the minimum annual contributions required by applicable regulators. We use a December 31 measurement date for our plans.

Effective December 30, 2015 our Netherlands plan was frozen with no expected future service credit as contributions for plan participants are now made to a defined contribution plan. This transition resulted in a plan curtailment as certain obligations of the defined benefit plan, included in the projected benefit obligations and plan asset tables below, remain with the Company.

The following table provides detail of Net periodic pension cost (benefit) for these four plans.



	Year Ended December 31,
($ in millions)	2016			2015		2014
Employer service cost - benefits earned during the period	$	2.0		4.7		3.7

We estimate $2.4 million will be recognized from AOCI into net periodic pension cost (benefit) during 2017.

The ranges of assumptions we used in developing the projected benefit obligation as of December 31 are presented in the following table.



	2016			2015
Discount rate used in determining present values	2.00%	to	2.70%	2.50%	to	3.90%
Annual increase in future compensation levels	0.00%	to	3.65%	0.00%	to	3.50%

The ranges of assumptions we used in determining net periodic cost (benefit) for the years ended December 31 are presented in the following table.



	2016			2015			2014
Discount rate used in determining present values	2.00%	to	3.90%	2.25%	to	3.70%	4.00%	to	4.65%
Annual increase in future compensation levels	0.00%	to	3.50%	0.00%	to	3.50%	0.00%	to	3.85%
Expected long-term rate of return on assets	2.00%	to	5.90%	2.70%	to	5.80%	4.10%	to	7.00%

The discount rate assumptions used for these pension plans were derived from the expected yield of investment grade bonds with durations consistent with the liabilities of these plans. The change in these discount rates was the primary driver of the actuarial losses and gains recognized in 2016 and 2015.

The expected long-term rate of return on assets is based on the current level of expected returns on risk-free investments (primarily government bonds), the historical level of the risk premium associated with various asset classes in which the portfolio is invested and the expectations for future returns of each asset class. The expected return for each asset class is then weighted based on the target asset allocation to develop the expected long-term rate of return on assets assumption for the portfolio.

Plan assets consist of diversified portfolios principally comprised of equity and debt securities. The investments and investment policies of these defined benefit plans are controlled by the trustees of each plan. The primary investment objective of these trusts is to invest plan assets in such a manner that members' benefit entitlements can be paid when they come due. Plan assets are invested with a long-term focus to achieve a return on investment based on levels of liquidity and investment risk the trustees, in consultation with the Company's management, believe are prudent and reasonable. These trusts set investment target allocations, but generally are not prohibited by the Company from investing in certain types of assets.

Pension plan assets measured at fair value and cash are presented in the following table with the overall allocation of pension plan assets.

The actual asset allocation as of December 31, 2016 and 2015 approximates each plan's target asset allocation percentages.

The Company's defined benefit plan in the Netherlands has its assets invested with a third party insurance company that guarantees the payment of vested benefits under this plan. The valuation of these assets was determined based on future benefits expected to be paid under this plan and is a Level 3 measurement. These assets are included in the Other category in the tables above.

Future contributions and payments - We expect to contribute $7.6 million to our defined benefit pension plans in 2017. In addition, pension benefit payments expected to be paid as of December 31, 2016, which reflect expected future service, as appropriate, are presented in the following table.
