2.	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Recent Accounting Pronouncements to be Adopted in Future Periods

In April 2014, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('ASU') No. 2014-08, 'Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity'. This guidance changes the criteria for reporting discontinued operations and enhances the related disclosures around discontinued operations. The new guidance requires a disposal of a component of an entity or a group of components of an entity to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. This guidance is effective for interim and annual periods beginning after December 15, 2014.

In May 2014, the FASB issued ASU No. 2014-09, 'Revenue From Contracts With Customers'. The new standard supersedes most current revenue recognition guidance and eliminates industry-specific guidance. The ASU is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. The ASU becomes effective for the Company at the beginning of its 2017 fiscal year; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. The Company is currently assessing the impact that this standard will have on its consolidated financial statements.

In June 2014, the FASB issued guidance on the accounting for stock compensation where share-based payment awards granted to employees required specific performance targets to be achieved in order for employees to become eligible to vest in the awards and such performance targets could be achieved after an employee completes the requisite service period. The amendment in this update requires a performance target that affects vesting and that could be achieved after the requisite service period to be treated as a performance condition. The guidance is applicable to the Company for interim and annual reporting periods beginning after December 15, 2015, although earlier adoption is permitted. The Company is currently assessing the impact that this standard will have on its consolidated financial statements.

Recent Accounting Pronouncements Adopted During the Period

In July 2013, the FASB issued ASU No. 2013-11, 'Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists', a consensus of the FASB Emerging Issues Task Force which provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward ('NOL'), or similar tax loss, or a tax credit carryforward exists. Such unrecognized tax benefits are required to be presented as a reduction of a deferred tax asset for a NOL or other tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed.

The Company adopted this guidance prospectively from January 1, 2014 and has not applied the amendments to the prior years. Upon adoption in the first quarter of 2014, other non-current liabilities and deferred tax assets were reduced by $21 million.

Significant Accounting Policies

These consolidated financial statements conform to accounting principles generally accepted in the United States of America (‘US GAAP’). Presented below are summaries of significant accounting policies followed in the preparation of the consolidated financial statements.

Certain reclassifications have been made to prior year amounts to conform to current year presentation. In particular, effective from January 1, 2014, the Company has made changes to the presentation of certain items within the Consolidated Statements of Operations. Foreign exchange gains and losses, primarily from balance sheet revaluation, and gains and losses from the disposal of operations, previously reported within 'Total operating expenses', are now reported in a new Statement of Operations line item, 'Other income (expense), net', which is reported below the 'Operating income (loss)' line item. Prior period amounts have been reclassified to conform to this presentation.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Willis Group Holdings and its subsidiaries, which are controlled through the ownership of a majority voting interest. Intercompany balances and transactions have been eliminated on consolidation.

Foreign Currency Translation

Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the functional currency are translated at the rates of exchange prevailing at the balance sheet date and the related transaction gains and losses are reported in the statements of operations. Certain intercompany loans are determined to be of a long-term investment nature. The Company records transaction gains and losses from remeasuring such loans as a component of other comprehensive income.

Upon consolidation, the results of operations of subsidiaries and associates whose functional currency is other than the US dollar are translated into US dollars at the average exchange rate and assets and liabilities are translated at year-end exchange rates. Translation adjustments are presented as a separate component of other comprehensive income in the financial statements and are included in net income only upon sale or liquidation of the underlying foreign subsidiary or associated company.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the year. In the preparation of these consolidated financial statements, estimates and assumptions have been made by management concerning: the valuation of intangible assets and goodwill (including those acquired through business combinations); the selection of useful lives of fixed and intangible assets; impairment testing; provisions necessary for accounts receivable, commitments and contingencies and accrued liabilities; long-term asset returns, discount rates and mortality rates in order to estimate pension liabilities and pension expense; income tax valuation allowances; and other similar evaluations. Actual results could differ from the estimates underlying these consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents primarily consist of time deposits with original maturities of three months or less.

Fiduciary Assets and Fiduciary Liabilities

In its capacity as an insurance agent or broker, the Company collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurers; the Company also collects claims or refunds from insurers which it then remits to insureds.

Fiduciary Assets

Fiduciary assets comprise Fiduciary Receivables and Fiduciary Funds.

Fiduciary Receivables

Fiduciary receivables represent uncollected premiums from insureds and uncollected claims or refunds from insurers.

Fiduciary Funds

Fiduciary funds represent unremitted premiums received from insureds and unremitted claims or refunds received from insurers. Fiduciary funds are generally required to be kept in certain regulated bank accounts subject to guidelines which emphasize capital preservation and liquidity. Such funds are not available to service the Company’s debt or for other corporate purposes. Notwithstanding the legal relationships with insureds and insurers, the Company is entitled to retain investment income earned on fiduciary funds in accordance with industry custom and practice and, in some cases, as supported by agreements with insureds.

The period for which the Company holds such funds is dependent upon the date the insured remits the payment of the premium to the Company, or the date the Company receives refunds from the insurers, and the date the Company is required to forward such payment to the insurer, or insured, respectively.

In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or insureds prior to collection. Such advances are made from fiduciary funds and are reflected in the accompanying consolidated balance sheets as fiduciary assets.

Fiduciary Liabilities

Fiduciary liabilities represent the obligations to remit fiduciary funds and fiduciary receivables to insurers or insureds.

Accounts Receivable

Accounts receivable are stated at estimated net realizable values. Allowances are recorded, when necessary, in an amount considered by management to be sufficient to meet probable future losses related to uncollectible accounts.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Expenditures for improvements are capitalized; repairs and maintenance are charged to expenses as incurred. Depreciation is computed using the straight-line method based on the estimated useful lives of assets.

Depreciation on buildings and long leaseholds is calculated over the lesser of 50 years or the lease term. Depreciation on leasehold improvements is calculated over the lesser of the useful life of the assets or the remaining lease term. Depreciation on furniture and equipment is calculated based on a range of 3 to 10 years. Freehold land is not depreciated.

Recoverability of Fixed Assets

Long-lived assets are tested for recoverability whenever events or changes in circumstance indicate that their carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. Recoverability is determined based on the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. Long-lived assets and certain identifiable intangible assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.

Operating Leases

Rentals payable on operating leases are charged straight line to expenses over the lease term as the rentals become payable.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the cost of businesses acquired over the fair value of identifiable net assets at the dates of acquisition. The Company reviews goodwill for impairment annually and whenever facts or circumstances indicate that the carrying amounts may not be recoverable. In testing for impairment, the fair value of each reporting unit is compared with its carrying value, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the amount of an impairment loss, if any, is calculated by comparing the implied fair value of reporting unit goodwill with the carrying amount of that goodwill.

Acquired intangible assets are amortized over the following periods:



		Expected
	Amortization basis	life (years)
Acquired client relationships	In line with underlying cashflows	5 to 20
Acquired management contracts	Straight line	18
Other intangible assets	Straight line	3 to 10

Amortizable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable.

Investments in Associates

Investments are accounted for using the equity method of accounting if the Company has the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if the Company has an equity ownership in the voting stock of the investee between 20 and 50 percent, although other factors, such as representation on the Board of Directors and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting the investment is carried at cost of acquisition, plus the Company’s equity in undistributed net income since acquisition, less any dividends received since acquisition.

The Company periodically reviews its investments in associates for which fair value is less than cost to determine if the decline in value is other than temporary. If the decline in value is judged to be other than temporary, the cost basis of the investment is written down to fair value. The amount of any write-down is included in the statements of operations as a realized loss.

All other equity investments where the Company does not have the ability to exercise significant influence are accounted for by the cost method. Such investments are not publicly traded.

GS & Cie Groupe ('Gras Savoye') is the principal associate of the Company. It is France's leading insurance broker. The Company has a call option to purchase 100 percent of the capital of Gras Savoye, a decision on whether to exercise this or not will be taken by April 30, 2015, for exercise during 2016.

The carrying amount of the Gras Savoye investment as of December 31, 2014 includes interest bearing vendor loans and convertible bonds issued by Gras Savoye of $41 million and $106 million respectively (2013: $46 million and $110 million, respectively).

Derivative Financial Instruments

The Company uses derivative financial instruments for other than trading purposes to alter the risk profile of an existing underlying exposure. Interest rate swaps have been used to manage interest risk exposures. Forward foreign currency exchange contracts are used to manage currency exposures arising from future income and expenses. The fair values of derivative contracts are recorded in other assets and other liabilities. The effective portions of changes in the fair value of derivatives that qualify for hedge accounting as cash flow hedges are recorded in other comprehensive income. Amounts are reclassified from other comprehensive income into earnings when the hedged exposure affects earnings. If the derivative is designated as, and qualifies as, an effective fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are both recognized in earnings. The amount of hedge ineffectiveness recognized in earnings is based on the extent to which an offset between the fair value of the derivative and hedged item is not achieved. Changes in fair value of derivatives that do not qualify for hedge accounting, together with any hedge ineffectiveness on those that do qualify, are recorded in other operating expenses or interest expense as appropriate.

The Company evaluates whether its contracts include clauses or conditions which would be required to be separately accounted for at fair value as embedded derivatives.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the estimated future tax consequences of events attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating and capital loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted rates in effect for the year in which the differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of changes in tax rates is recognized in the statement of operations in the period in which the change is enacted. Deferred tax assets are reduced through the establishment of a valuation allowance at such time as, based on available evidence, it is more likely than not that the deferred tax assets will not be realized. The Company adjusts valuation allowances to measure deferred tax assets at the amount considered realizable in future periods if the Company’s facts and assumptions change. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations.

Positions taken in the Company’s tax returns may be subject to challenge by the taxing authorities upon examination. The Company recognizes the benefit of uncertain tax positions in the financial statements when it is more likely than not that the position will be sustained on examination by the tax authorities upon lapse of the relevant statute of limitations, or when positions are effectively settled. The benefit recognized is the largest amount of tax benefit that is greater than 50 percent likely to be realized on settlement with the tax authority, assuming full knowledge of the position and all relevant facts. The Company adjusts its recognition of these uncertain tax benefits in the period in which new information is available impacting either the recognition or measurement of its uncertain tax positions. Such adjustments are reflected as increases or decreases to income taxes in the period in which they are determined.

The Company recognizes interest and penalties relating to unrecognized tax benefits within income taxes.

Provisions for Liabilities

The Company is subject to various actual and potential claims, lawsuits and other proceedings. The Company records liabilities for such contingencies including legal costs when it is probable that a liability has been incurred before the balance sheet date and the amount can be reasonably estimated. To the extent such losses can be recovered under the Company’s insurance programs, estimated recoveries are recorded when losses for insured events are realized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. The Company analyzes its litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters, to assess its potential liability. Contingent liabilities are not discounted.

Pensions

The Company has two principal defined benefit pension plans which cover approximately half of employees in the United States and United Kingdom. Both these plans are now closed to new entrants. New employees in the United Kingdom are offered the opportunity to join a defined contribution plan and in the United States are offered the opportunity to join a 401(k) plan. In addition to the Company’s UK and US defined benefit pension plans, the Company has several smaller defined benefit pension plans in certain other countries in which it operates including a US non-qualified plan and an unfunded plan in the UK.. Elsewhere, pension benefits are typically provided through defined contribution plans.

Defined benefit plans

The net periodic cost of the Company’s defined benefit plans are measured on an actuarial basis using the projected unit credit method and several actuarial assumptions the most significant of which are the discount rate and the expected long-term rate of return on plan assets. Other material assumptions include rates of participant mortality, the expected long-term rate of compensation and pension increases and rates of employee termination. Gains and losses occur when actual experience differs from actuarial assumptions. If such gains or losses exceed ten percent of the greater of plan assets or plan liabilities the Company amortizes those gains or losses over the average remaining service period or average remaining life expectancy as appropriate of the plan participants.

In accordance with US GAAP the Company records on the balance sheet the funded status of its pension plans based on the projected benefit obligation.

Defined contribution plans

Contributions to the Company’s defined contribution plans are recognized as they fall due. Differences between contributions payable in the year and contributions actually paid are shown as either other assets or other liabilities in the consolidated balance sheets.

Share-Based Compensation

The Company has equity-based compensation plans that provide for grants of restricted stock units and stock options

to employees and non-employee directors of the Company who perform services for the Company.

The Company expenses all equity-based compensation on a straight-line basis over the requisite service period based upon the fair value of the award on the date of grant, the estimated achievement of any performance targets and anticipated staff retention. The awards under equity-based compensation are classified as equity and included as a component of equity on the Company’s consolidated balance sheets, as the ultimate payment of such awards will not be achieved through use of the Company’s cash or other assets.

Revenue Recognition

Revenue includes insurance commissions, fees for services rendered, certain commissions receivable from insurance carriers, investment income and other income.

Brokerage income and fees negotiated in lieu of brokerage are recognized at the later of the policy inception date or when the policy placement is complete. Commissions on additional premiums and adjustments are recognized when approved by or agreed between the parties and collectability is reasonably assured.

Fees for risk management and other services are recognized as the services are provided. Consideration for negotiated fee arrangements for an agreed period covering multiple insurance placements, the provision of risk management and/or other services are allocated to all deliverables on the basis of their relative selling prices. The Company establishes contract cancellation reserves where appropriate: at December 31, 2014, 2013 and 2012, such amounts were not material.

Investment income is recognized as earned.

Other income comprises gains on disposal of intangible assets, which primarily arise from settlements through enforcing non-compete agreements in the event of losing accounts through producer defection or the disposal of books of business.

- Definition

The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability.

SHARE-BASED COMPENSATION



4.	SHARE-BASED COMPENSATION

On December 31, 2014, the Company had a number of open share-based compensation plans, which provide for the grant of time-based options and performance-based options, time-based restricted stock units and performance-based restricted stock units, and various other share-based grants to employees. All of the Company’s share-based compensation plans under which any options, restricted stock units or other share-based grants are outstanding as at December 31, 2014 are described below. The compensation cost that has been recognized for those plans for the year ended December 31, 2014 was $52 million (2013: $42 million; 2012: $32 million). The total income tax benefit recognized in the statement of operations for share-based compensation arrangements for the year ended December 31, 2014 was $12 million (2013: $9 million; 2012: $9 million).

2012 Equity Incentive Plan

This plan, which was established on April 25, 2012, provides for the granting of incentive stock options, time-based or performance-based non-statutory stock options, share appreciation rights, restricted shares, time-based or performance-based restricted share units ('RSUs'), performance-based awards and other share-based grants or any combination thereof (collectively referred to as 'Awards') to employees, officers, directors and consultants ('Eligible Individuals') of the Company. The Board of Directors also adopted a sub-plan under the 2012 plan to provide an employee sharesave scheme in the United Kingdom.

There are 13,776,935 shares available for grant under this plan. In addition, shares subject to awards that were granted under the Willis Group Holdings 2008 Share Purchase and Option Plan, that terminate, expire or lapse for any reason will be made available for future Awards under this Plan. Options are exercisable on a variety of dates, including from the second, third, fourth or fifth anniversary of grant. Unless terminated sooner by the Board of Directors, the 2012 Plan will expire 10 years after the date of its adoption. That termination will not affect the validity of any grants outstanding at that date.

2008 Share Purchase and Option Plan

This plan, which was established on April 23, 2008, provides for the granting of time and performance-based options, restricted stock units and various other share-based grants at fair market value to employees of the Company. The 2008 plan was terminated as at April 25, 2012 and no further grants will be made under this plan. Any shares available for grant under the 2008 plan were included in the 2012 Equity Incentive Plan availability.

Options are exercisable on a variety of dates, including from the third, fourth or fifth anniversary of grant.

Employee Stock Purchase Plans

The Company adopted the Willis Group Holdings 2001 North America Employee Share Purchase Plan, which expired on May 31, 2011 and the Willis Group Holdings 2010 North America Employee Stock Purchase Plan, which expires on May 31, 2020. These plans provide certain eligible employees in the United States and Canada the ability to contribute payroll deductions to the purchase of Willis Group Holdings plc shares at the end of each offering period.

Option Valuation Assumptions

The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table. Expected volatility is based on historical volatility of the Company’s stock. The Company uses the simplified method set out in Accounting Standard Codification (‘ASC’) 718-10-S99 to derive the expected term of options granted as it does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The risk-free rate for periods within the expected life of the option is based on the US Treasury yield curve in effect at the time of grant.



	Years ended December 31,
	2014		2013		2012

As a result of certain realization requirements of ASC 718 Compensation - Stock Compensation, the Company recognized $8 million of previously unrecognized deferred tax assets that arose directly from tax deductions related to equity compensation greater than compensation recognized for financial reporting. Equity was increased by this $8 million as of December 31, 2014.

At December 31, 2014, the Company had valuation allowances of $280 million (2013: $196 million) to reduce its deferred tax assets to estimated realizable value. The valuation allowances at December 31, 2014, relate to deferred tax assets arising from UK capital loss carryforwards ($39 million) and other net operating losses ($10 million), which have no expiration date, and to the deferred tax assets in the United States ($231 million). Included within US deferred tax assets are assets of $76 million in respect of US state net operating losses. These losses will expire as follows: $8 million from 2015 to 2018, $17 million from 2019 to 2023 and $51 million from 2024 to 2034. Capital loss carryforwards can only be offset against future UK capital gains.

The amount charged to tax expense in the table above differs from the effect of $7 million disclosed in the rate reconciliation primarily because the movement in this table includes effects of state taxes, which are disclosed separately in the rate reconciliation. The impact of Other movements is primarily recorded in other comprehensive income.

At December 31, 2014 the Company had deferred tax assets of $146 million (2013: $187 million), net of the valuation allowance. Management believes, based upon the level of historical taxable income and projections for future taxable income, it is more likely than not that the Company will realize the benefits of these deductible differences, net of the valuation allowance. However, the amount of the deferred tax asset considered realizable could be adjusted in the future if estimates of taxable income are revised.

The Company recognizes deferred tax balances related to the undistributed earnings of subsidiaries when the Company expects that it will recover those undistributed earnings in a taxable manner, such as through receipt of dividends or sale of the investments. The Company does not, however, provide for income taxes on the unremitted earnings of certain other subsidiaries where, in management’s opinion, such earnings have been indefinitely reinvested in those operations, or will be remitted either in a tax free liquidation or as dividends with taxes substantially offset by foreign tax credits. It is not practical to determine the amount of unrecognized deferred tax liabilities for temporary differences related to these investments.

Unrecognized tax benefits

Total unrecognized tax benefits as at December 31, 2014, totaled $19 million. During the next 12 months it is reasonably possible that the Company will recognize approximately $1 million of tax benefits related to the release of provisions for potential inter company pricing adjustments no longer required due to either settlement through negotiation or closure of the statute of limitations on assessment.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:



	2014			2013			2012
	(millions)
Balance at January 1	$	41		$	37		$	16
Reductions due to a lapse of the applicable statute of limitation	—			(5		)	(3		)

(Decreases) increases for positions taken in prior periods	(26		)	—			16
Other movements	(1		)	—			—
Balance at December 31	$	19		$	41		$	37

$19 million of the unrecognized tax benefits at December 31, 2014 would, if recognized, favorably affect the effective tax rate in future periods.

The Company files tax returns in the various tax jurisdictions in which it operates. US tax returns have been filed timely. Although tax years 2008 and 2009 are closed, the IRS could make adjustments (but not assess additional tax) up to the amount of the net operating losses carried forward from those years. The Company extended the federal statute of limitations for assessment in the United States for the 2010 year until March 15, 2015.

All UK tax returns have been filed timely and are in the normal process of being reviewed, by HM Revenue & Customs. There are no material ongoing inquiries in relation to filed UK returns. In other tax jurisdictions the Company is currently not subject to any examinations for any year prior to 2004.

Earnings Per Share [Abstract]

EARNINGS PER SHARE



9.	EARNINGS PER SHARE

Basic and diluted earnings per share are calculated by dividing net income (loss) attributable to Willis Group Holdings by the average number of shares outstanding during each period. The computation of diluted earnings per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issue of shares that then shared in the net income of the Company.

In periods where losses are reported the weighted average shares outstanding excludes potentially issuable shares described above, because their inclusion would be anti-dilutive.

For the year ended December 31, 2014, time-based and performance-based options to purchase 5.7 million and 3.7 million shares (2013: 8.0 million and 5.3 million; 2012: 10.2 million and 6.5 million), respectively, and 3.5 million restricted stock units (2013: 2.9 million; 2012: 2.5 million) were outstanding.

Basic and diluted earnings per share are as follows:



	Years ended December 31,
	2014			2013			2012
	(millions, except per share data)
Net income (loss) attributable to Willis Group Holdings	$	362		$	365		$	(446	)
Basic weighted average number of shares outstanding	178			176			173
Dilutive effect of potentially issuable shares	3			3			—
Diluted weighted average number of shares outstanding	181			179			173
Basic earnings per share:
Net income (loss) attributable to Willis Group Holdings shareholders	$	2.03		$	2.07		$	(2.58	)
Dilutive effect of potentially issuable shares	(0.03		)	(0.03		)	—
Diluted earnings per share:
Net income (loss) attributable to Willis Group Holdings shareholders	$	2.00		$	2.04		$	(2.58	)

Options to purchase 2.4 million shares and 1.5 million restricted stock units for the year ended December 31, 2014, were not included in the computation of the dilutive effect of stock options because the effect was antidilutive (2013: 2.1 million shares and 1.3 million restricted stock units; 2012: 16.7 million shares and 2.5 million restricted stock units).

10.	ACQUISITIONS

During the years ended December 31, 2014 and 2013 we made the following material acquisitions in line with our strategy to invest in targeted acquisitions with a focus on earnings accretion, competitive position, and fit.

Max Matthiessen Holding AB

In the fourth quarter of 2014, the Company acquired 75.8 percent of Max Matthiessen Holding AB and subsidiaries (collectively referred to as Max Matthiessen), a leading employee benefits adviser in Sweden, for cash consideration of $204 million.

On acquisition the Company recognized acquired intangible assets of $134 million of which $56 million was in relation to client relationships and $76 million was in relation to fund management contracts, which are being amortized over 12 years and 18 years respectively.

In the second quarter of 2014, the Company acquired 100 percent of Charles Monat Limited and its subsidiaries (collectively referred to as Charles Monat), a life insurance solutions adviser to high net worth clients based in Hong Kong, for cash consideration of $59 million.

Additional consideration estimated at $29 million is payable in annual installments over the next 5 years, based on a multiple of EBITDA of the entities acquired, during the period from May 25, 2014 until September 2, 2019. This consideration has been assessed to have a fair value of $12 million at the date of acquisition.

On acquisition the Company recognized acquired intangible assets of $35 million of which $27 million was in respect of client relationships, which are being amortized over an expected life of 11 years. The remaining $8 million of intangible assets relate to carrier relationships and trade names and are both being amortized over 5 years.

Goodwill of $31 million was recognized on the transaction.

Prime Professions Ltd

In second quarter 2013, the Company acquired 100 percent of PPH Limited and its subsidiary Prime Professions Limited (together referred to as Prime Professions), a leading UK based professional indemnity insurance broker, for cash consideration of $29 million. Additional consideration of up to approximately $2 million is payable in 2015 based on the achievement of certain revenue targets.

In relation to the acquisition of Prime Professions, the Company recognized acquired intangible assets of $17 million of which $16 million was in respect of client relationships, which are being amortized over an expected life of 15 years. The remaining intangible assets relate to non-compete agreements and the Prime trade name which are being amortized over 8 years and 3 years, respectively.

Goodwill

Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL



12.	GOODWILL

Goodwill represents the excess of the cost of businesses acquired over the fair value of identifiable net assets at the dates of acquisition. Goodwill is not amortized but is subject to impairment testing annually and whenever facts or circumstances indicate that the carrying amounts may not be recoverable.

The Company has determined that its reporting units are consistent with its operating segments: North America; International and Global. Goodwill is allocated to these reporting units based on the original purchase price allocation for acquisitions within the reporting units. When a business entity is sold, goodwill is allocated to the disposed entity based on the fair value of that entity compared to the fair value of the reporting unit in which it is included.

The changes in the carrying amount of goodwill by reporting unit for the years ended December 31, 2014 and 2013, are as follows:



	Global			North America			International			Total
	(millions)
Balance at January 1, 2013

_________________________________

⁽ⁱ⁾

Effective January 1, 2014, the Company changed its internal reporting structure: UK Retail, previously reported within the International segment, is now reported within the Global segment; Mexico Retail, which was previously reported within the North America segment, is now reported in the International segment; and the US captive consulting and facultative reinsurance businesses, both previously reported within the North America segment, are now reported within the Global segment. As a consequence of these changes goodwill has been reallocated between reporting units using the relative fair value allocation approach.

Impairment Review

The Company reviews goodwill for impairment annually, or whenever events of circumstances indicate impairment may have occurred. In the first step of the impairment test, the fair value of each reporting unit is compared with its carrying value, including goodwill. If the carrying value of a reporting unit exceeds its fair value, the amount of an impairment loss, if any, is calculated in the second step of the impairment test by comparing the implied fair value of reporting unit goodwill with the carrying amount of that goodwill.

The Company's goodwill impairment test for 2014 has not resulted in an impairment charge (2013: $nil; 2012: $492 million).

In 2012, as a consequence of the Company's annual goodwill impairment test performed as of October 1, 2012, the Company concluded that a pre-tax impairment charge of $492 million was required to reduce the carrying value of the goodwill associated with the Company's North America reporting unit from $1,782 million to its implied fair value of $1,290 million. The Company used the income approach to measure the fair value of the North America reporting unit, which involved calculating the fair value of the reporting unit based on the present value of the estimated future cash flows. Cash flow projections were based on management's estimates of revenue growth rates and operating margins, taking into consideration industry and market conditions and the uncertainty related to the business's ability to execute on the projected cash flows. The discount rate used was based on the weighted-average cost of capital adjusted for the relevant risk associated with market participant expectations of characteristics of the reporting unit. The unobservable inputs included projected revenue growth rates, profitability and the market participant assumptions within the discount rate. The decline in the estimated fair value of the reporting unit resulted from lower projected revenue growth rates and profitability levels as well as an increase in the discount rate used to calculate discounted cash flows. As a consequence of the significance of unobservable inputs developed using company-specific information, the re-measurement of goodwill for this reporting unit is classified as a non-recurring level 3 fair value assessment.

Pension Plans



17.	PENSION PLANS

The Company maintains two principal defined benefit pension plans that cover approximately half of the Company's employees in the United States and United Kingdom. Both of these plans are now closed to new entrants and with effect from May 15, 2009, the Company closed the US defined benefit plan to future accrual. New employees in the United Kingdom are offered the opportunity to join a defined contribution plan and in the United States are offered the opportunity to join a 401(k) plan.

Fair Value Hierarchy

The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value:


•	Level 1: refers to fair values determined based on quoted market prices in active markets for identical assets;


•	Level 2: refers to fair values estimated using observable market based inputs or unobservable inputs that are corroborated by market data; and


•	Level 3: includes fair values estimated using unobservable inputs that are not corroborated by market data.

The following tables present, at December 31, 2014 and 2013, for each of the fair value hierarchy levels, the Company’s UK pension plan assets that are measured at fair value on a recurring basis.

The UK plan’s real estate investment comprises UK property and infrastructure investments which are valued by the fund manager taking into account cost, independent appraisals and market based comparable data. The UK plan’s hedge fund investments are primarily invested in various ‘fund of funds’ and are valued based on net asset values calculated by the fund and are not publicly available. Liquidity is typically monthly and is subject to liquidity of the underlying funds. The UK plan’s Other Government Bonds investments are primarily invested in investment-grade emerging and developed market government bonds. Funds are valued on a net asset value basis, with the underlying bond instruments being valued using bid-side, clean pricing from approved pricing vendors. Prices are not publicly available.

The following tables present, at December 31, 2014 and 2013, for each of the fair value hierarchy levels, the Company’s US pension plan assets that are measured at fair value on a recurring basis.

Equity securities comprise:


•	ordinary shares and preferred shares which are valued using quoted market prices; and


•	pooled investment vehicles which are valued at their net asset values as calculated by the investment manager and typically have daily or weekly liquidity.

Fixed income securities comprise US, UK and other Government Treasury Bills, loan stock, index linked loan stock and UK and other corporate bonds which are typically valued using quoted market prices. Certain of these investments are classified as Level 2 investments on the basis that the assets are valued at their net asset values calculated by the investment manager and liquidity is not daily.

Level 3 investments

As a result of the inherent limitations related to the valuations of the Level 3 investments, due to the unobservable inputs of the underlying funds, the estimated fair value may differ significantly from the values that would have been used had a market for those investments existed.

The following table summarizes the changes in the UK pension plan’s Level 3 assets for the years ended December 31, 2014 and 2013:

Term loans and revolving credit facilities

On July 23, 2013 the Company entered into an amendment to its existing credit facilities to extend both the amount of financing and the maturity date of the facilities. As a result of this amendment, the Company's revolving credit facility was increased from $500 million to $800 million. The maturity date on both the revolving credit facility and the $300 million term loan was extended to July 23, 2018, from December 16, 2016, respectively. At the amendment date the Company owed $281 million on the term loan and there was no change to this amount as a result of the refinancing.

The 7-year term loan facility expiring 2018 bears interest at LIBOR plus 1.50% and is repayable in quarterly installments and a final repayment of $186 million is due in the third quarter of 2018. In 2014, the Company made $15 million of mandatory repayments against this 7-year term loan. Drawings under the $800 million revolving credit facility bear interest at LIBOR plus 1.50%. These margins apply while the Company’s debt rating remains BBB-/Baa3. As of December 31, 2014 $nil was outstanding under this revolving credit facility (December 31, 2013: $nil).

The agreements relating to the Company's 7-year term loan facility expiring 2018 and the revolving $800 million credit facility contain requirements to maintain maximum levels of consolidated funded indebtedness in relation to consolidated EBITDA and minimum level of consolidated EBITDA to consolidated cash interest expense, subject to certain adjustments. In addition, the agreements relating to the Company's credit facilities and senior notes include, in the aggregate covenants relating to the delivery of financial statements, reports and notices, limitations on liens, limitations on sales and other disposals of assets, limitations on indebtedness and other liabilities, limitations on sale and leaseback transactions, limitations on mergers and other fundamental changes, maintenance of property, maintenance of insurance, nature of business, compliance with applicable laws, maintenance of corporate existence and rights, payment of taxes and access to information and properties. At December 31, 2014, the Company was in compliance with all covenants.

On March 3, 2014, Willis Securities, Inc., a wholly-owned indirect subsidiary of Willis Group Holdings plc, entered into a $300 million revolving note and cash subordination agreement available for drawing from March 3, 2014 through March 3, 2015.

The aggregate unpaid principal amount of all advances is repayable on or before March 3, 2016.

On April 28, 2014, the Company entered into an amendment to the $300 million revolving note and cash subordination

agreement to increase the amount of financing and to extend both the end date of the original credit period and the original

repayment date. As a result of this amendment, the revolving credit facility was increased from $300 million to $400 million.

The end date of the credit period was extended to April 28, 2015 from March 3, 2015 and the repayment date was extended to

April 28, 2016 from March 3, 2016. As of December 31, 2014 $nil was outstanding under this revolving credit facility.

Proceeds under the credit facility will be used for regulatory capital purposes related to securities underwriting only, which will

allow Willis Securities to meet or exceed capital requirements of regulatory agencies, self-regulatory agencies and their clearing

houses, including the Financial Industry Regulatory Authority. Advances under the credit facility bear interest at a rate

equal to (a) for Eurocurrency Loans, LIBOR plus 1.50% to 2.25%, and (b) for base rates Loans, the highest of (i) the Federal

Funds rates plus 0.5%, (ii) the 'prime rate' as announced by SunTrust Bank, and (iii) LIBOR plus 1.00%, plus 0.5% to 1.25%, in

each case, based upon the Company’s guaranteed senior-unsecured long-term debt rating.

Senior Notes

On August 15, 2013 the Company issued $250 million of 4.625% senior notes due 2023 and $275 million of 6.125% senior notes due 2043. The effective interest rates of these senior notes are 4.696% and 6.154%, respectively, which include the impact of the discount upon issuance.

On July 25, 2013 the Company commenced an offer to purchase for cash any and all of its 5.625% senior notes due 2015 and a portion of its 6.200% senior notes due 2017 and its 7.000% senior notes due 2019 for an aggregate purchase price of up to $525 million. On August 22, 2013 the proceeds from the issue of the senior notes due 2023 and 2043 were used to fund the purchase of $202 million of 5.625% senior notes due 2015, $206 million of 6.200% senior notes due 2017 and $113 million of 7.000% senior notes due 2019.

The Company incurred total losses on extinguishment of debt of $60 million during the year ended December 31, 2013. This was made up of a tender premium of $65 million, the write-off of unamortized debt issuance costs of $2 million and a credit for the reduction of the fair value adjustment on 5.625% senior notes due 2015 of $7 million.

Lines of credit

The Company also has available $3 million (2013: $4 million) in lines of credit, of which $1 million was drawn as of December 31, 2014 (2013: $nil).

⁽ⁱⁱⁱ⁾	The above excludes $19 million of liabilities for unrecognized tax benefits as the Company is unable to reasonably predict the timing of settlement of these liabilities.

Debt obligations and facilities

The Company’s debt and related interest obligations at December 31, 2014 are shown in the above table.

Mandatory repayments of debt over the next 12 months include expiration of the 3-year term loan facility expiring 2015, maturity of the 5.625% senior notes due 2015 and the scheduled repayment of the current portion of the Company’s 7-year term loan. The Company also has the right, at its option, to prepay indebtedness under the credit facility without further penalty and to redeem the senior notes by paying a ‘make-whole’ premium as provided under the applicable debt instrument.

Operating leases

The Company leases certain land, buildings and equipment under various operating lease arrangements. Original non-cancellable lease terms typically are between 10 and 20 years and may contain escalation clauses, along with options that permit early withdrawal. The total amount of the minimum rent is expensed on a straight-line basis over the term of the lease.

As of December 31, 2014, the aggregate future minimum rental commitments under all non-cancellable operating lease agreements are as follows:



	Gross rental commitments		Rentals from subleases			Net rental commitments
			(millions)
2015	$	128	$	(13	)	$	115
2016	115		(13		)	102
2017	106		(12		)	94

2019	84		(5		)	79
Thereafter	657		(10		)	647
Total	$	1,181	$	(60	)	$	1,121

The Company leases its main London building under a 25-year operating lease, which expires in 2032. The Company’s contractual obligations in relation to this commitment included in the table above total $645 million (2013: $719 million). Annual rentals are $36 million (2013: $36 million) per year and the Company has subleased approximately 29 percent (2013: 29 percent) of the premises under leases up to 15 years. The amounts receivable from subleases, included in the table above, total $51 million (2013: $66 million; 2012: $76 million).

Rent expense amounted to $134 million for the year ended December 31, 2014 (2013: $141 million; 2012: $135 million). The Company’s rental income from subleases was $13 million for the year ended December 31, 2014 (2013: $15 million; 2012: $17 million).

Pensions

Contractual obligations for the Company's pension plans reflect the contributions the Company expects to make over the next five years into the US, UK and Other defined benefit plans. These contributions are based on current funding positions and may increase or decrease dependent on the future performance of the plans.

In the United Kingdom, the Company is required to agree a funding strategy for the UK defined benefit plan with the plan's trustees. In March 2012, the Company agreed to a revised schedule of contributions towards on-going accrual of benefits and deficit funding contributions the Company will make to the UK plan over the six years ended December 31, 2017. Contributions in each of the next three years would total approximately $75 million, of which approximately $19 million relates to on-going contributions calculated as 15.9 percent of active plan members' pensionable salary and approximately $56 million that relates to contributions towards the funding deficit.

In addition, based on this agreement, further contributions would be payable based on a profit share calculation (equal to 20 percent of EBITDA in excess of $900 million per annum as defined by the revised schedule of contributions) and an exceptional return calculation (equal to 10 percent of any exceptional returns made to shareholders, for example, share buybacks, and special dividends). The Company expects to make an exceptional return contribution of $21 million during 2015 as a result of share buyback activity during 2014. Aggregate contributions under the deficit funding contribution and the profit share calculation are capped at £312 million ($486 million) over the six years ended December 31, 2017.

We are currently negotiating a new funding arrangement which we are required to do every three years, which may further change the contributions we are required to make during 2015 and beyond.

An additional amount of approximately $10 million will be paid annually into the UK defined benefit plan related to employee's salary sacrifice contributions.

The total contracted contributions for all plans in 2015 are expected to be approximately $116 million, excluding approximately $10 million in respect of the salary sacrifice contributions.

Guarantees

Guarantees issued by certain of Willis Group Holdings’ subsidiaries with respect to the senior notes and revolving credit facilities are discussed in Note 18 — Debt.

Certain of Willis Group Holdings’ subsidiaries have given the landlords of some leasehold properties occupied by the Company in the United Kingdom and the United States guarantees in respect of the performance of the lease obligations of the subsidiary holding the lease. The operating lease obligations subject to such guarantees amounted to $756 million and $828 million at December 31, 2014 and 2013, respectively. The capital lease obligations subject to such guarantees amounted to $11 million as at December 31, 2014 (2013: $11 million).

In addition, the Company has given guarantees to bankers and other third parties relating principally to letters of credit amounting to $20 million and $11 million at December 31, 2014 and 2013, respectively. Willis Group Holdings also guarantees certain of its UK and Irish subsidiaries’ obligations to fund the UK and Irish defined benefit plans.

Other contractual obligations

For certain subsidiaries and associates, the Company has the right to purchase shares (a call option) from co-shareholders at various dates in the future. In addition, the co-shareholders of certain subsidiaries and associates have the right to sell their shares (a put option) to the Company at various dates in the future. Generally, the exercise price of such put options and call options is formula-based (using revenues and earnings) and is designed to reflect fair value. Based on current projections of profitability and exchange rates and assuming the put options are exercised, the potential amount payable from these options is not expected to exceed $72 million (2013: $12 million).

In July 2010, the Company made a capital commitment of $25 million to Trident V Parallel Fund, LP, an investment fund managed by Stone Point Capital. This replaced a capital commitment of $25 million that had been made to Trident V, LP in December 2009. As at December 31, 2014 there have been approximately $22 million of capital contributions.

In May 2011, the Company made a capital commitment of $10 million to Dowling Capital Partners I, LP. As at December 31, 2014 there had been approximately $7 million of capital contributions.

Other contractual obligations at December 31, 2014, also include certain capital lease obligations totaling $64 million (2013: $63 million), primarily in respect of the Company's Nashville property.

Claims, Lawsuits and Other Proceedings

In the ordinary course of business, the Company is subject to various actual and potential claims, lawsuits, and other

proceedings relating principally to alleged errors and omissions in connection with the placement of insurance and reinsurance.

Similar to other corporations, the Company is also subject to a variety of other claims, including those relating to the

Company’s employment practices. Some of the claims, lawsuits and other proceedings seek damages in amounts which could,

if assessed, be significant.

The material actual or potential claims, lawsuits, and other proceedings, of which the Company is currently aware, are as follows:

Stanford Financial Group Litigation

The Company has been named as a defendant in 13 similar lawsuits relating to the collapse of The Stanford Financial Group (‘Stanford’), for which Willis of Colorado, Inc. acted as broker of record on certain lines of insurance. The complaints in these actions generally allege that the defendants actively and materially aided Stanford’s alleged fraud by providing Stanford with certain letters regarding coverage that they knew would be used to help retain or attract actual or prospective Stanford client investors. The complaints further allege that these letters, which contain statements about Stanford and the insurance policies that the defendants placed for Stanford, contained untruths and omitted material facts and were drafted in this manner to help Stanford promote and sell its allegedly fraudulent certificates of deposit.

Errors and omissions claims, lawsuits, and other proceedings arising in the ordinary course of business are covered in part by

professional indemnity or other appropriate insurance. The terms of this insurance vary by policy year and self-insured risks

have increased significantly in recent years. Regarding self-insured risks, the Company has established provisions which are

believed to be adequate in the light of current information and legal advice, and the Company adjusts such provisions from time

to time according to developments. These provisions have been recognized in other operating expenses to the extent that losses are deemed probable and reasonably estimable. Matters that are not probable or reasonably estimable have not been provided for and the Company does not believe a reasonable possible range of losses, for these matters, can be estimated.

On the basis of current information, the Company does not expect that the actual claims, lawsuits and other proceedings to

which the Company is subject, or potential claims, lawsuits, and other proceedings relating to matters of which it is aware, will

ultimately have a material adverse effect on the Company’s financial condition, results of operations or liquidity. Nonetheless,

given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation and

disputes with insurance companies, it is possible that an adverse outcome in certain matters could, from time to time, have a

material adverse effect on the Company’s results of operations or cash flows in particular quarterly or annual periods.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES



24.	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES

Fair value of derivative financial instruments

In addition to the note below, see Note 25 - Fair Value Measurements for information about the fair value hierarchy of derivatives.

Primary risks managed by derivative financial instruments

The main risks managed by derivative financial instruments are interest rate risk and foreign currency risk. The Company’s Board of Directors reviews and approves policies for managing each of these risks as summarized below.

The Company enters into derivative transactions (principally interest rate swaps and forward foreign currency contracts) in order to manage interest rate and foreign currency risks arising from the Company’s operations and its sources of finance. The Company does not hold financial or derivative instruments for trading purposes.

Interest Rate Risk — Investment Income

As a result of the Company’s operating activities, the Company holds Fiduciary funds. The Company earns interest on these funds, which is included in the Company’s financial statements as investment income. These funds are regulated in terms of access and the instruments in which they may be invested, most of which are short-term in maturity.

Through the fourth quarter of 2011, in order to manage interest rate risk relating to Fiduciary funds, the Company entered into interest rate swaps to receive a fixed rate of interest and pay a variable rate of interest denominated in the various currencies related to the short-term investments. During the second quarter 2012, the Company closed out its legacy position relating to such instruments. The fair value of these swaps at the close out date was $16 million, representing a cash settlement amount on termination. In connection with the terminated swaps, the Company retained a gain of $15 million in accumulated other comprehensive income. This gain is being reclassified into earnings in line with the forecasted swap transactions. The Company expects approximately $1 million of the gain to be recognized in the consolidated statement of operations in 2015.

At December 31, 2014 and 2013, the Company had no derivative financial instruments that were designated as cash flow hedges of interest rate risk in investments.

Interest Rate Risk — Interest Expense

The Company's operations are financed principally by $2,054 million fixed rate senior notes maturing through 2043 and $259 million under a 7-year term loan facility. The Company has access to (i) $800 million under a revolving credit facility expiring July 23, 2018, (ii) $400 million under a revolving credit facility expiring April 28, 2015, which will be available for regulatory capital purposes related to securities underwriting only, and (iii) $22 million under two further revolving credit facilities, of which $20 million is also only available for specific regulatory purposes. As of December 31, 2014 $nil (2013: $nil) was drawn on these facilities.

The 7-year term loan facility bears interest at LIBOR plus 1.50% and drawings under the revolving credit facility bear interest at LIBOR plus 1.50%. These margins apply while the Company’s debt rating remains BBB-/Baa3. Should the Company’s debt rating change, then the margin will change in accordance with the credit facilities agreements. The fixed rate senior notes bear interest at various rates as detailed in Note 18 — ‘Debt’.

During the year ended December 31, 2010, the Company entered into a series of interest rate swaps for a total notional amount of $350 million to receive a fixed rate and pay a variable rate on a semi-annual basis, with a maturity date of July 15, 2015. The Company had previously designated these instruments as fair value hedges against its $350 million 5.625% senior notes due 2015 and had accounted for them accordingly until the first quarter of 2013 at which point these swaps, although remaining as economic hedges, no longer qualified for hedge accounting.

During the year ended December 31, 2013, the Company closed out the above interest rate swaps and received a cash settlement of $13 million on termination.

To hedge against the potential variability in benchmark interest rates in advance of the anticipated debt issuance, the Company entered into two short-term treasury locks during the three months ended June 30, 2013. These were closed out during the three months ended September 30, 2013 following the issue of the new senior notes described in Note 18 - 'Debt'. The fair value of these treasury locks at the close out date was $21 million, received as a cash settlement on termination.

The Company had designated the Treasury locks as effective hedges of the anticipated transaction and had recognized a gain of $19 million in other comprehensive income in relation to the effective element that qualified for hedge accounting at that date. This amount will be reclassified into earnings consistent with the recognition of interest expense on the 4.625% senior notes due 2023 and the 6.125% senior notes due 2043. In addition, the Company recognized a $2 million gain in interest expense in the year ended December 31, 2013 for the portion of the treasury locks determined as ineffective.

Foreign Currency Risk

The Company’s primary foreign exchange risks arise:

•

from changes in the exchange rate between US dollars and pounds sterling as its London market operations earn the majority of their revenues in US dollars and incur expenses predominantly in Pounds sterling, and may also hold a significant net sterling asset or liability position on the balance sheet. In addition, the London market operations earn significant revenues in Euros and Japanese yen; and


•	from the translation into US dollars of the net income and net assets of its foreign subsidiaries, excluding the London market operations which are US dollar denominated.

The foreign exchange risks in its London market operations are hedged as follows:


•	to the extent that forecast Pound sterling expenses exceed Pound sterling revenues, the Company limits its exposure to this exchange rate risk by the use of forward contracts matched to specific, clearly identified cash outflows arising in the ordinary course of business; and

•

to the extent the UK operations earn significant revenues in Euros and Japanese yen, the Company limits its exposure to changes in the exchange rate between the US dollar and these currencies by the use of forward contracts matched to a percentage of forecast cash inflows in specific currencies and periods. In addition, we are also exposed to foreign exchange risk on any net sterling asset or liability position in our London market operations.

The fair value of foreign currency contracts is recorded in other assets and other liabilities. For contracts that qualify as accounting hedges, changes in fair value resulting from movements in the spot exchange rate are recorded as a component of other comprehensive income whilst changes resulting from a movement in the time value are recorded in interest expense. For contracts that do not qualify for hedge accounting, the total change in fair value is recorded in interest expense. Amounts held in comprehensive income are reclassified into earnings when the hedged exposure affects earnings.

At December 31, 2014 and 2013, the Company’s foreign currency contracts were all designated as hedging instruments except for those relating to short-term cash flows and hedges of certain intercompany loans.

The table below summarizes by major currency the contractual amounts of the Company’s forward contracts to exchange foreign currencies for Pounds sterling in the case of US dollars and US dollars for euro and Japanese yen. Foreign currency notional amounts are reported in US dollars translated at contracted exchange rates.

US dollar	$	678	$	303
Euro	186		97
Japanese yen	51		35

_________________________________


⁽ⁱ⁾	Forward exchange contracts range in maturity from 2015 to 2017.

In addition to forward exchange contracts, we undertake short-term foreign exchange swaps for liquidity purposes. These are not designated as hedges and do not qualify for hedge accounting. The fair values at December 31, 2014 and 2013 were immaterial.

During the year ended December 31, 2014, the Company entered into a number of foreign currency transactions in order to hedge certain intercompany loans. These derivatives were not designated as hedging instruments and were for a total notional amount of $352 million (December 31, 2013: $228 million). In respect of these transactions, an immaterial amount has been recognized as an asset within other current assets and an equivalent gain has been recognized in other income (expense), net, for the period.

In addition during the year ended December 31, 2014, in order to hedge the Company's exposure relating to the purchase price consideration for acquiring a 75.8 percent holding in Max Matthiessen AB, the Company entered into a series of forward exchange contracts. As a result of these transactions the Company recognized a $14 million expense in other income (expense), net, and an equivalent reduction to cash and cash equivalents in the year.

Derivative financial instruments

The table below presents the fair value of the Company’s derivative financial instruments and their balance sheet classification at December 31:



		Fair value

_________________________________

Amounts above shown gross of tax.


⁽ⁱ⁾	OCI means other comprehensive income.

For interest rate swaps all components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. For foreign exchange contracts, only the changes in fair value resulting from movements in the spot exchange rate are included in this assessment. In instances where the timing of expected cash flows can be matched exactly to the maturity of the foreign exchange contract, then changes in fair value attributable to movement in the forward points are also included.

At December 31, 2014 the Company estimates there will be $7 million of net derivative gains reclassified from accumulated comprehensive income into earnings within the next twelve months as the forecasted transactions affect earnings.

Credit Risk and Concentrations of Credit Risk

Credit risk represents the loss that would be recognized at the reporting date if counterparties failed to perform as contracted and from movements in interest rates and foreign exchange rates. The Company currently does not anticipate non-performance by its counterparties. The Company generally does not require collateral or other security to support financial instruments with credit risk.

Concentrations of credit risk that arise from financial instruments exist for groups of customers or counterparties when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions. Financial instruments on the balance sheet that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, fiduciary funds, accounts receivable and derivatives which are recorded at fair value.

The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places such investments in an extensive number of financial institutions to limit the amount of credit risk exposure. These financial institutions are monitored on an ongoing basis for credit quality predominantly using information provided by credit agencies.

Concentrations of credit risk with respect to receivables are limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas. Management does not believe significant risk exists in connection with the Company's concentrations of credit as of December 31, 2014.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS



25.	FAIR VALUE MEASUREMENTS

The Company has categorized its assets and liabilities that are measured at fair value on a recurring and non-recurring basis into a three-level fair value hierarchy, based on the reliability of the inputs used to determine fair value as follows:


•	Level 1: refers to fair values determined based on quoted market prices in active markets for identical assets;


•	Level 2: refers to fair values estimated using observable market based inputs or unobservable inputs that are corroborated by market data; and


•	Level 3: includes fair values estimated using unobservable inputs that are not corroborated by market data.

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments:

Long-term debt (excluding related fair value hedges)-Fair values are based on quoted market values and so classified as Level 1 measurements.

Derivative financial instruments-Market values have been used to determine the fair value of interest rate swaps and forward foreign exchange contracts based on estimated amounts the Company would receive or have to pay to terminate the agreements, taking into account the current interest rate environment or current foreign currency forward rates. Such financial instruments are classified as Level 2 in the fair value hierarchy.

Financial instruments measured at fair value on a recurring basis

The following table presents, for each of the fair-value hierarchy levels, the Company's assets and liabilities that are measured at fair value on a recurring basis.

Segment Reporting [Abstract]

SEGMENT INFORMATION



26.	SEGMENT INFORMATION

During the periods presented, the Company operated through three reporting segments: Global, North America and International. Global provides specialist brokerage and consulting services to clients worldwide for specific industrial and commercial activities and is organized by specialism. North America and International predominantly comprise our retail operations which provide services to small, medium and large corporations, accessing Global’s specialist expertise when required.

The Company uses segment operating income (loss) to measure segment performance. The Company does not allocate all expenses that form part of total expenses in the consolidated statements of operations to its operating segments because management does not include this information in its measurement of the performance of those segments. Because of this unallocated expense, the operating income (loss) of each reporting segment does not reflect the operating income (loss) reporting segment would report as a stand-alone business.

The accounting policies of the segments are consistent with those described in Note 2 — 'Basis of Presentation and Significant Accounting Policies'.

There are no inter-segment revenues, with segments operating on a revenue-sharing basis equivalent to that used when sharing business with other third-party brokers.

Selected information regarding the Company’s segments is as follows:

30.	FINANCIAL INFORMATION FOR ISSUER, PARENT GUARANTOR, OTHER GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES

Trinity Acquisition Limited (previously registered as Trinity Acquisition plc) has $525 million senior notes outstanding that were issued on August 15, 2013.

All direct obligations under the senior notes were jointly and severally, irrevocably and fully and unconditionally guaranteed by Willis Netherlands Holdings B.V, Willis Investment UK Holdings Limited, TA I Limited, Willis Group Limited and Willis North America, Inc, collectively the 'Other Guarantors', and with Willis Group Holdings, the 'Guarantor Companies'.

The guarantor structure described above differs from the guarantor structure associated with the senior notes issued by the Company and Willis North America (the ‘Willis North America Debt Securities’) in that Trinity Acquisition Limited is the issuer and not a subsidiary guarantor, and Willis North America, Inc. is a subsidiary guarantor.

Presented below is condensed consolidating financial information for:


(i)	Willis Group Holdings, which is a guarantor, on a parent company only basis;


(ii)	the Other Guarantors, which are all 100 percent directly or indirectly owned subsidiaries of the parent. Willis Netherlands Holdings B.V, Willis Investment UK Holdings Limited and TA I Limited are all direct or indirect parents of the issuer and Willis Group Limited and Willis North America Inc., are 100 percent directly or indirectly owned subsidiaries or the issuer;


(iii)	Trinity Acquisition Limited, which is the issuer and is a 100 percent indirectly owned subsidiary of the parent;


(iv)	Other, which are the non-guarantor subsidiaries, on a combined basis;


(v)	Consolidating adjustments; and


(vi)	the Consolidated Company.

The equity method has been used for investments in subsidiaries in the condensed consolidating balance sheets of Willis Group Holdings, the Other Guarantors and the Issuer.

The following 100 percent directly or indirectly owned subsidiaries fully and unconditionally guarantee the Holdings Debt Securities on a joint and several basis: Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, TA I Limited, Trinity Acquisition Limited (previously registered as Trinity Acquisition plc), Willis Group Limited and Willis North America (the ‘Guarantors’).

The guarantor structure described above differs from the guarantor structure associated with the senior notes issued by Willis North America (the ‘Willis North America Debt Securities’) (and for which condensed consolidating financial information is presented in Note 30) in that Willis Group Holdings is the Parent Issuer and Willis North America is a subsidiary guarantor.

Presented below is condensed consolidating financial information for:


(i)	Willis Group Holdings, which is the Parent Issuer;


(ii)	the Guarantors, which are all 100 percent directly or indirectly owned subsidiaries of the parent;


(iii)	Other, which are the non-guarantor subsidiaries, on a combined basis;


(iv)	Consolidating adjustments; and


(v)	the Consolidated Company.

The equity method has been used for investments in subsidiaries in the condensed consolidating balance sheets for the year ended December 31, 2014 of Willis Group Holdings and the Guarantors.
