28. Retirement Benefit Obligations

The Group operates either defined benefit or defined contribution pension schemes in all of its principal operating areas. The disclosures included below relate to all pension schemes in the Group.

The Group operates defined benefit pension schemes in Belgium, Brazil, Canada, France, Germany, Italy, the Netherlands, the Philippines, the Republic of Ireland, Romania, Serbia, Slovakia, Switzerland, the UK and the US. The Group has a mixture of funded and unfunded defined benefit pension schemes. The net liability of the funded schemes is €175 million (2016: €444 million). Unfunded obligations (including jubilee, post-retirement healthcare obligations and long-term service commitments) comprise of a number of schemes in Brazil, Canada, France, Germany, Italy, the Netherlands, the Philippines, Romania, Serbia, Slovakia, Switzerland and the US, totalling a net liability of €202 million (2016: €147 million).

Funded defined benefit schemes in the Republic of Ireland, Switzerland and the UK are administered by separate funds that are legally distinct from the Group under the jurisdiction of Trustees. The Trustees of these pension funds are required by law and by their Articles of Association to act in the best interests of the scheme participants and are responsible for the definition of investment strategy and for scheme administration. Other schemes are also administered in line with the local regulatory environment. The level of benefits available to most members depends on length of service and either their average salary over their period of employment or their salary in the final years leading up to retirement. The Group’s pension schemes in Switzerland are contribution-based schemes with guarantees to provide further contributions in the event that certain targets are not met, largely in relation to investment return and the annuity conversion factor on retirement.

Defined benefit pension schemes - principal risks

Through its defined benefit pension and jubilee schemes, long-term service commitments and post-retirement healthcare plans, the Group is exposed to a number of risks, the most significant of which are detailed below:

Asset volatility: Under IAS 19, the assets of the Group’s defined benefit pension schemes are reported at fair value (using bid prices, where relevant). The majority of the schemes’ assets comprise equities, bonds and property, all of which may fluctuate significantly in value from period to period. Given that liabilities are discounted to present value based on bond yields and that bond prices are inversely related to yields, an increase in the liability discount rate (which would reduce liabilities) would reduce bond values, though not necessarily by an equal magnitude.

Given the maturity of certain of the Group’s funded defined benefit pension schemes, de-risking frameworks have been introduced to mitigate deficit volatility and enable better matching of investment returns with the cash outflows related to benefit obligations. These frameworks entail the usage of asset-liability matching techniques, whereby triggers are set for the conversion of equity holdings into bonds of similar average duration to the relevant liabilities.

Discount rates: The discount rates employed in determining the present value of the schemes’ liabilities are determined by reference to market yields at the balance sheet date on high-quality corporate bonds of a currency and term consistent with the currency and term of the associated post-employment benefit obligations. Changes in discount rates impact the quantum of liabilities as discussed above.

Inflation risk: A significant amount of the Group’s pension obligations are linked to inflation; higher inflation will lead to higher liabilities (although in most cases, caps on the level of inflationary increases are in place to protect the schemes against extreme inflation).

Longevity risk: In the majority of cases, the Group’s defined benefit pension schemes provide benefits for life with spousal and dependent child reversionary provisions; increases in life expectancy will therefore give rise to higher liabilities.

Aggregation

For the purposes of the disclosures which follow for 2017, 2016 and 2015; the schemes in Belgium, France, Germany, Italy, the Netherlands, the Republic of Ireland and Slovakia have been aggregated into a “Eurozone” category on the basis of common currency and financial assumptions; schemes in Brazil, the Philippines, Romania, Serbia and the UK have been aggregated into an “Other” category.

Financial assumptions - scheme liabilities

The major long-term assumptions used by the Group’s actuaries in the computation of scheme liabilities as at 31 December 2017, 31 December 2016 and 31 December 2015 are as follows:


	Eurozone						Switzerland						United States and Canada
	2017 %		2016 %		2015 %		2017 %		2016 %		2015 %		2017 %		2016 %		2015 %
Rate of increase in:
- salaries		3.59		3.41		3.64		1.25		1.25		1.75		3.27		3.28		3.29
- pensions in payment		1.70		1.50		1.75		-		-		-		-		-		-
Inflation		1.75		1.50		1.75		0.75		0.75		0.75		2.00		2.00		2.00
Discount rate		2.05		1.86		2.61		0.70		0.65		0.85		3.52		4.01		4.22
Medical cost trend rate		n/a		n/a		n/a		n/a		n/a		n/a		6.33		5.98		6.21

The mortality assumptions employed in determining the present value of scheme liabilities under IAS 19 represent actuarial best practice in the relevant jurisdictions, taking account of mortality experience and industry circumstances. For schemes in the Republic of Ireland and the UK, the mortality assumptions used are in accordance with the underlying funding valuations. For the Group’s most material schemes, the future life expectations factored into the relevant valuations, based on retirement at 65 years of age for current and future retirees, are as follows:


	Republic of Ireland						Switzerland						United States and Canada
	2017		2016		2015		2017		2016		2015		2017		2016		2015
Current retirees
- male		22.7		22.5		22.8		22.4		22.3		21.5		20.6		20.5		21.2
- female		24.4		24.3		24.9		24.4		24.3		24.0		23.1		23.0		23.4

Future retirees
- male		25.5		25.4		25.8		24.6		24.6		23.6		22.3		22.3		23.0
- female		27.0		26.9		26.9		26.6		26.6		26.0		24.7		24.7		25.1

The above data allows for future improvements in life expectancy.

Impact on Consolidated Income Statement

The total retirement benefit expense from continuing operations in the Consolidated Income Statement is as follows:


	2017 €m		2016 €m		2015 €m
Total defined contribution expense		237		232		204

Total defined benefit (credit)/expense		(1)		75		77
Total expense in Consolidated Income Statement		236		307		281

At 31 December 2017, €78 million (2016: €89 million) was included in other payables relating to defined contribution pension liabilities.

Actuarial valuations - funding requirements and future cash flows

In accordance with statutory requirements in the Republic of Ireland and minimum funding requirements in the UK, additional annual contributions and lump-sum payments are required to certain of the schemes in place in those jurisdictions. The funding requirements in relation to the Group’s defined benefit schemes are assessed in accordance with the advice of independent and qualified actuaries and valuations are prepared in this regard either annually, where local requirements mandate that this be done, or at triennial intervals at a maximum in all other cases. In the Republic of Ireland and the UK, either the attained age or projected unit credit methods are used in the valuations. In the Netherlands and Switzerland, the actuarial valuations reflect the current unit method, while the valuations are performed in accordance with the projected unit credit methodology in Germany. In the US, valuations are performed using a variety of actuarial cost methodologies - current unit, projected unit and aggregate cost. In Canada, the projected unit credit method is used in valuations. The dates of the funding valuations range from April 2015 to July 2017.

In general, funding valuations are not available for public inspection; however, the results of valuations are advised to the members of the various schemes on request.

The Group’s contracted payments (on a discounted basis) to certain schemes is €18 million (2016: €35 million; 2015: €52 million) in the Republic of Ireland and €16 million (2016: €20 million; 2015: €21 million) in the UK. The maturity profile of the Group’s contracted payments (on a discounted basis) is as follows:


	Total
	2017 €m		2016 €m		2015 €m
Within one year		19		20		20
Between one and two years		2		19		19
Between two and three years		2		2		19
Between three and four years		2		2		2
Between four and five years		1		2		2
After five years		8		10		11
		34		55		73

Employer contributions payable in the 2018 financial year including minimum funding payments (expressed using year-end exchange rates for 2017) are estimated at €112 million.
