BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	'
	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	The accompanying condensed consolidated financial statements (‘Interim Financial Statements’) have been prepared in accordance with accounting principles generally accepted in the United States of America (‘US GAAP’).
	The Interim Financial Statements are unaudited but include all adjustments (consisting of normal recurring adjustments) which the Company’s management considers necessary for a fair presentation of the financial position as of such dates and the operating results and cash flows for those periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted. However, the Company believes that the disclosures are adequate to make the information presented not misleading. The results of operations for the nine months ended September 30, 2014 may not necessarily be indicative of the operating results for the entire fiscal year.
	These Interim Financial Statements should be read in conjunction with the Company’s consolidated balance sheets as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive income, cash flows and changes in equity for each of the three years in the period ended December 31, 2013 included in the Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 27, 2014.
	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 reported in a new statement of operations line item, 'Other (expense) income, net', which is reported below Operating income. Prior period amounts have been reclassified to conform to this presentation.
	In July 2013, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('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.
	This standard is effective prospectively for annual and interim reporting periods beginning after December 15, 2013. 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.
	In April 2014, the FASB issued 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.

RESTRUCTURING COSTS	'
	RESTRUCTURING COSTS
	The Operational Improvement Program is a multi-year program and is expected to be completed by the end of 2017. The main elements of the program include the following:
	•	movement of more than 3,500 support roles from higher cost locations to Willis facilities in lower cost locations, bringing the ratio of employees in higher cost versus lower cost near-shore and off-shore centers from approximately 80:20 to approximately 60:40;
	•	net workforce reductions in support positions;
	•	lease consolidation in real estate and reductions in ratios of seats per employee and square footage of floor space per employee; and
	•	information technology systems simplification and rationalization.
	The Company recognized restructuring costs of $17 million and $20 million in the three and nine months ended September 30, 2014 related to its Operational Improvement Program.
	An analysis of the cost for restructuring recognized in the statement of operations in the three and nine months ended September 30, 2014 is as follows:

	As reported	$	380		$	(88	)	23	%
	For interim income tax reporting purposes, the Company determines its best estimate of an annual effective tax rate and applies that rate to its year-to-date ordinary income. The Company's estimated annual effective tax rate excludes significant, unusual, or infrequently occurring items and certain other items excluded pursuant to the US GAAP authoritative guidance where applicable. The income tax expense (or benefit) related to all other items is individually computed and recognized when the items occur.
	The reported tax rate for the three months ended September 30, 2014 was negative 20 percent compared with negative 73 percent for the same period of 2013. The reported tax rate for the nine months ended September 30, 2014 was 31 percent compared with 23 percent for the same period of 2013.
	The tax rate in the three months ended September 30, 2014 was affected by a catch up charge of $4 million as a result of an increase in the estimate of the annual effective tax rate applied to ordinary income of the prior two quarters. The tax rate in the three months ended September 30, 2013 was higher mainly due to charges related to the early extinguishment of debt that was issued by Willis North America in a prior period. As previously disclosed, the Company currently maintains a valuation allowance against net US deferred tax assets. Therefore, no tax benefit was recognized for the debt extinguishment charges, resulting in a large negative tax rate for the period.
	The higher tax rate in the nine months ended September 30, 2014 compared to the same period of 2013 was partly due to the expectation of paying current taxes in the United States in 2014, which resulted in a higher tax charge on US income in the current period compared with the prior period. In addition, there was a $21 million increase to the US valuation allowance against deferred tax assets. This was an incremental increase to the valuation allowance caused by the release of provisions for uncertain tax positions.
	The Company's tax rate differs from the US statutory income tax rate of 35 percent primarily due to income being subject to tax in numerous non-US jurisdictions with varying tax rates, as well as the valuation allowance maintained in the United States due to losses incurred in recent years.

EARNINGS PER SHARE	'
	EARNINGS PER SHARE
	Basic and diluted earnings per share are calculated by dividing net (loss) income 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 issuance of shares that then shared in the net income of the Company.
	In periods where losses are reported, the weighted average shares outstanding excludes the potentially issuable shares described above because their inclusion would be antidilutive.
	At September 30, 2014, time-based and performance-based options to purchase 5.8 million and 4.5 million shares (September 30, 2013: 7.8 million and 5.6 million), respectively, and 2.9 million restricted stock units (September 30, 2013: 1.7 million) were outstanding.
	Basic and diluted earnings per share are as follows:
		Three months ended September 30,							Nine months ended September 30,

	Options to purchase 2.1 million shares were not included in the computation of the dilutive effect of stock options for the nine months ended September 30, 2014 (nine months ended September 30, 2013: 3.8 million).

	During the nine months ended September 30, 2014, the Company made cash contributions of $61 million (2013: $68 million) into the UK defined benefit pension plan. In addition to this, a further payment of $9 million (2013: $9 million) was made in respect of employees’ salary sacrifice contributions. Cash contributions of $2 million and $8 million (2013: $40 million and $8 million) were made to the US plan and other defined benefit pension plans, respectively.
	Contributions to the UK defined benefit pension plan in 2014 are expected to total $81 million, of which approximately $22 million relates to ongoing contributions calculated as 15.9 percent of active plan members’ pensionable salaries and approximately $59 million relates to contributions towards funding the deficit.
	In addition, for full year 2014, the Company expects to contribute approximately $12 million to the UK defined benefit pension plan related to employees’ salary sacrifice contributions. The Company also expects to contribute approximately $25 million to the US plan and $10 million to the other defined benefit pension plans for the full year 2014 (inclusive of amounts contributed in the year to date).
	Further contributions will be payable into the UK pension plan 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). In respect of 2014, any such contributions will be paid in 2015 on finalization of the calculations. Aggregate contributions under the deficit funding contribution and the profit share calculation are capped at £312 million ($506 million) over the six-year period ended December 31, 2017.
	The schedule of contributions is required to be renegotiated after three years or at any earlier time jointly agreed by the Company and the trustee. The Company is currently in negotiations with the plan’s Trustee to agree an updated funding strategy.

	Other Contractual Obligations
	In July 2010, the Company made a capital commitment of $25 million to Trident V Parallel Fund, LP. As of September 30, 2014, there had been approximately $21 million of capital contributions towards this commitment.
	In May 2011, the Company made a capital commitment of $10 million to Dowling Capital Partners I, LP. As of September 30, 2014, there had been approximately $5 million of capital contributions towards this commitment.
	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.
	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 light of current information and legal advice, and the Company adjusts such provisions from time to time according to developments.
	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.
	The material actual and potential claims, lawsuits, and other proceedings, of which the Company is currently aware, are set forth below.
	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.
	The 13 actions are as follows:
	•	Troice, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:09-CV-1274-N, was filed on July 2, 2009 in the U.S. District Court for the Northern District of Texas against Willis Group Holdings plc, Willis of Colorado, Inc. and a Willis associate, among others. On April 1, 2011, plaintiffs filed the operative Third Amended Class Action Complaint individually and on behalf of a putative, worldwide class of Stanford investors, adding Willis Limited as a defendant and alleging claims under Texas statutory and common law and seeking damages in excess of $1 billion, punitive damages and costs. On May 2, 2011, the defendants filed motions to dismiss the Third Amended Class Action Complaint, arguing, inter alia, that the plaintiffs’ claims are precluded by the Securities Litigation Uniform Standards Act of 1998 (‘SLUSA’).
	On May 10, 2011, the court presiding over the Stanford-related actions in the Northern District of Texas entered an order providing that it would consider the applicability of SLUSA to the Stanford-related actions based on the decision in a separate Stanford action not involving a Willis entity, Roland v. Green, Civil Action No. 3:10-CV-0224-N. On August 31, 2011, the court issued its decision in Roland, dismissing that action with prejudice under SLUSA.
	On October 27, 2011, the court in Troice entered an order (i) dismissing with prejudice those claims asserted in the Third Amended Class Action Complaint on a class basis on the grounds set forth in the Roland decision discussed above and (ii) dismissing without prejudice those claims asserted in the Third Amended Class Action Complaint on an individual basis. Also on October 27, 2011, the court entered a final judgment in the action.
	On October 28, 2011, the plaintiffs in Troice filed a notice of appeal to the U.S. Court of Appeals for the Fifth Circuit. Subsequently, Troice, Roland and a third action captioned Troice, et al. v. Proskauer Rose LLP, Civil Action No. 3:09-CV-01600-N, which also was dismissed on the grounds set forth in the Roland decision discussed above and on appeal to the U.S. Court of Appeals for the Fifth Circuit, were consolidated for purposes of briefing and oral argument. Following the completion of briefing and oral argument, on March 19, 2012, the Fifth Circuit reversed and remanded the actions. On April 2, 2012, the defendants-appellees filed petitions for rehearing en banc. On April 19, 2012, the petitions for rehearing en banc were denied. On July 18, 2012, defendants-appellees filed a petition for writ of certiorari with the United States Supreme Court regarding the Fifth Circuit's reversal in Troice. On January 18, 2013, the Supreme Court granted our petition. Opening briefs were filed on May 3, 2013 and the Supreme Court heard oral argument on October 7, 2013. On February 26, 2014, the Supreme Court affirmed the Fifth Circuit's decision.
	On March 19, 2014, the plaintiffs in Troice filed a Motion to Defer Resolution of Motions to Dismiss, to Compel Rule 26(f) Conference and For Entry of Scheduling Order. That motion has now been fully briefed by the parties and awaits disposition by the court.
	On March 25, 2014, the parties in Troice and the Janvey, et al. v. Willis of Colorado, Inc., et al. action discussed below stipulated to the consolidation of the two actions for pre-trial purposes under Rule 42(a) of the Federal Rules of Civil Procedure. On March 28, 2014, the Court “so ordered” that stipulation and, thus, consolidated Troice and Janvey for pre-trial purposes under Rule 42(a).
	On September 16, 2014, the court (a) denied the plaintiffs’ request to defer resolution of the defendants’ motions to dismiss, but granted the plaintiffs’ request to enter a scheduling order; (b) requested the submission of supplemental briefing by all parties on the defendants’ motions to dismiss, which the parties submitted on September 30, 2014; and (c) entered an order setting a schedule for briefing and discovery regarding plaintiffs’ motion for class certification, which schedule, among other things, provides for the submission of the plaintiffs’ motion for class certification (following the completion of briefing and discovery) on April 20, 2015.
	•	Ranni v. Willis of Colorado, Inc., et al., C.A. No. 09-22085, was filed on July 17, 2009 against Willis Group Holdings plc and Willis of Colorado, Inc. in the U.S. District Court for the Southern District of Florida. The complaint was filed on behalf of a putative class of Venezuelan and other South American Stanford investors and alleges claims under Section 10(b) of the Securities Exchange Act of 1934 (and Rule 10b-5 thereunder) and Florida statutory and common law and seeks damages in an amount to be determined at trial. On October 6, 2009, Ranni was transferred, for consolidation or coordination with other Stanford-related actions (including Troice), to the Northern District of Texas by the U.S. Judicial Panel on Multidistrict Litigation (the ‘JPML’). The defendants have not yet responded to the complaint in Ranni. On August 26, 2014, the plaintiff filed a notice of voluntary dismissal of the action without prejudice.
	•	Canabal, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:09-CV-1474-D, was filed on August 6, 2009 against Willis Group Holdings plc, Willis of Colorado, Inc. and the same Willis associate named as a defendant in Troice, among others, also in the Northern District of Texas. The complaint was filed individually and on behalf of a putative class of Venezuelan Stanford investors, alleged claims under Texas statutory and common law and sought damages in excess of $1 billion, punitive damages, attorneys’ fees and costs. On December 18, 2009, the parties in Troice and Canabal stipulated to the consolidation of those actions (under the Troice civil action number), and, on December 31, 2009, the plaintiffs in Canabal filed a notice of dismissal, dismissing the action without prejudice.
	•	Rupert, et al. v. Winter, et al., Case No. 2009C115137, was filed on September 14, 2009 on behalf of 97 Stanford investors against Willis Group Holdings plc, Willis of Colorado, Inc. and the same Willis associate, among others, in Texas state court (Bexar County). The complaint alleges claims under the Securities Act of 1933, Texas and Colorado statutory law and Texas common law and seeks special, consequential and treble damages of more than $300 million, attorneys’ fees and costs. On October 20, 2009, certain defendants, including Willis of Colorado, Inc., (i) removed Rupert to the U.S. District Court for the Western District of Texas, (ii) notified the JPML of the pendency of this related action and (iii) moved to stay the action pending a determination by the JPML as to whether it should be transferred to the Northern District of Texas for consolidation or coordination with the other Stanford-related actions. On April 1, 2010, the JPML issued a final transfer order for the transfer of Rupert to the Northern District of Texas. On January 24, 2012, the court remanded Rupert to Texas state court (Bexar County), but stayed the action until further order of the court. The defendants have not yet responded to the complaint in Rupert.
	•	Casanova, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:10-CV-1862-O, was filed on September 16, 2010 on behalf of seven Stanford investors against Willis Group Holdings plc, Willis Limited, Willis of Colorado, Inc. and the same Willis associate, among others, also in the Northern District of Texas. The complaint alleges claims under Texas statutory and common law and seeks actual damages in excess of $5 million, punitive damages, attorneys’ fees and costs. The defendants have not yet responded to the complaint in Casanova.
	•	Rishmague, et ano. v. Winter, et al., Case No. 2011CI2585, was filed on March 11, 2011 on behalf of two Stanford investors, individually and as representatives of certain trusts, against Willis Group Holdings plc, Willis of Colorado, Inc., Willis of Texas, Inc. and the same Willis associate, among others, in Texas state court (Bexar County). The complaint alleges claims under Texas and Colorado statutory law and Texas common law and seeks special, consequential and treble damages of more than $37 million and attorneys’ fees and costs. On April 11, 2011, certain defendants, including Willis of Colorado, Inc., (i) removed Rishmague to the Western District of Texas, (ii) notified the JPML of the pendency of this related action and (iii) moved to stay the action pending a determination by the JPML as to whether it should be transferred to the Northern District of Texas for consolidation or coordination with the other Stanford-related actions. On August 8, 2011, the JPML issued a final transfer order for the transfer of Rishmague to the Northern District of Texas, where it is currently pending. On September 9, 2014, the court remanded Rishmague to Texas state court (Bexar County), but stayed the action until further order of the court. The defendants have not yet responded to the complaint in Rishmague.
	•	MacArthur v. Winter, et al., Case No. 2013-07840, was filed on February 8, 2013 on behalf of two Stanford investors against Willis Group Holdings plc, Willis of Colorado, Inc., Willis of Texas, Inc. and the same Willis associate, among others, in Texas state court (Harris County). The complaint alleges claims under Texas and Colorado statutory law and Texas common law and seeks actual, special, consequential and treble damages of approximately $4 million and attorneys' fees and costs. On March 29, 2013, Willis of Colorado, Inc. and Willis of Texas, Inc. (i) removed MacArthur to the U.S. District Court for the Southern District of Texas and (ii) notified the JPML of the pendency of this related action. On April 2, 2013, Willis of Colorado, Inc. and Willis of Texas, Inc. filed a motion in the Southern District of Texas to stay the action pending a determination by the JPML as to whether it should be transferred to the Northern District of Texas for consolidation or coordination with the other Stanford-related actions. Also on April 2, 2013, the court presiding over MacArthur in the Southern District of Texas transferred the action to the Northern District of Texas for consolidation or coordination with the other Stanford-related actions. On September 29, 2014, the parties stipulated to the remand (to Texas state court (Harris County)) and stay of MacArthur until further order of the court (in accordance with the court’s September 9, 2014 decision in Rishmague (discussed above)), which stipulation was “so ordered” by the court on October 14, 2014. The defendants have not yet responded to the complaint in MacArthur.
	•	Florida suits: On February 14, 2013, five law suits were filed against Willis Group Holdings plc, Willis Limited and Willis of Colorado, Inc. in Florida state court (Miami-Dade County) alleging violations of Florida common law. The five suits are: (1) Barbar, et al. v. Willis Group Holdings Public Limited Company, et al., Case No. 13-05666CA27, filed on behalf of 35 Stanford investors seeking compensatory damages in excess of $30 million; (2) de Gadala-Maria, et al. v. Willis Group Holdings Public Limited Company, et al., Case No. 13-05669CA30, filed on behalf of 64 Stanford investors seeking compensatory damages in excess of $83.5 million; (3) Ranni, et ano. v. Willis Group Holdings Public Limited Company, et al., Case No. 13-05673CA06, filed on behalf of two Stanford investors seeking compensatory damages in excess of $3 million; (4) Tisminesky, et al. v. Willis Group Holdings Public Limited Company, et al., Case No. 13-05676CA09, filed on behalf of 11 Stanford investors seeking compensatory damages in excess of $6.5 million; and (5) Zacarias, et al. v. Willis Group Holdings Public Limited Company, et al., Case No. 13-05678CA11, filed on behalf of 10 Stanford investors seeking compensatory damages in excess of $12.5 million. On June 3, 2013, Willis of Colorado, Inc. removed all five cases to the Southern District of Florida and, on June 4, 2013, notified the JPML of the pendency of these related actions. On June 10, 2013, the court in Tisminesky issued an order sua sponte staying and administratively closing that action pending a determination by the JPML as to whether it should be transferred to the Northern District of Texas for consolidation and coordination with the other Stanford-related actions. On June 11, 2013, Willis of Colorado, Inc. moved to stay the other four actions pending the JPML's transfer decision. On June 20, 2013, the JPML issued a conditional transfer order for the transfer of the five actions to the Northern District of Texas, the transmittal of which was stayed for seven days to allow for any opposition to be filed. On June 28, 2013, with no opposition having been filed, the JPML lifted the stay, enabling the transfer to go forward. On September 30, 2014, the court denied the plaintiffs’ motion to remand in Zacarias, and, on October 3, 2014, the court denied the plaintiffs’ motions to remand in Tisminesky and de Gadala Maria. The defendants have not yet responded to the complaints in these actions.
	•	Janvey, et al. v. Willis of Colorado, Inc., et al., Case No. 3:13-CV-03980-D, was filed on October 1, 2013 also in for the Northern District of Texas against Willis Group Holdings plc, Willis Limited, Willis North America Inc., Willis of Colorado, Inc. and the same Willis associate. The complaint was filed (i) by Ralph S. Janvey, in his capacity as Court-Appointed Receiver for the Stanford Receivership Estate, and the Official Stanford Investors Committee (the ‘OSIC’) against all defendants and (ii) on behalf of a putative, worldwide class of Stanford investors against Willis North America Inc. Plaintiffs Janvey and the OSIC allege claims under Texas common law and the court’s Amended Order Appointing Receiver, and the putative class plaintiffs allege claims under Texas statutory and common law. Plaintiffs seek actual damages in excess of $1 billion, punitive damages and costs. On November 15, 2013, plaintiffs filed the operative First Amended Complaint, which added certain defendants unaffiliated with Willis. On February 28, 2014, the defendants filed motions to dismiss the First Amended Complaint, which motions have now been fully briefed by the parties and await disposition by the court.
	As discussed above, on March 25, 2014, the parties in Troice and Janvey stipulated to the consolidation of the two actions for pre-trial purposes under Rule 42(a) of the Federal Rules of Civil Procedure. On March 28, 2014, the Court “so ordered” that stipulation and, thus, consolidated Troice and Janvey for pre-trial purposes under Rule 42(a).
	Additional actions could be brought in the future by other investors in certificates of deposit issued by Stanford and its affiliates. The Company disputes these allegations and intends to defend itself vigorously against these actions. The outcomes of these actions, however, including any losses or other payments that may occur as a result, cannot be predicted at this time.

	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
	Fair Value of Derivative Financial Instruments
	In addition to the note below, see Note 10 — ‘Fair Value Measurement’ 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 receives cash for premiums and claims which it deposits in short-term investments denominated in US dollars and other currencies. 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.
	In order to manage interest rate risk arising from these financial assets, the Company may enter 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. The use of interest rate contracts essentially converted groups of short-term variable rate investments to fixed rate investments. The fair value of these contracts was recorded in other assets and other liabilities. For contracts that qualified as cash flow hedges for accounting purposes, the effective portions of changes in fair value were recorded as a component of other comprehensive income, to the extent that the hedge relationships were highly effective.
	During the three and nine months ended September 30, 2014 and three and nine months ended September 30, 2013, the Company had no derivative financial instruments that were designated as cash flow hedges of interest rate risk on 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 $263 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.
	The 7-year term loan facility bears interest at LIBOR plus 1.50%. As of September 30, 2014, $nil was drawn on the $800 million revolving credit facility. 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.
	As of September 30, 2014, $nil was drawn on the $400 million revolving credit facility. Advances under that credit facility shall 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.
	The fixed rate senior notes bear interest at various rates as detailed in Note 16 — ‘Debt’.
	During the three months ended March 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 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. The Company closed out these interest rate swaps in 2013 and received a cash settlement of $13 million on termination.
	Following the partial extinguishment of the 5.625% senior notes due 2015 on August 15, 2013, the Company recorded a credit of $7 million removing a corresponding partial amount of the fair value adjustment to the carrying values of the notes originally recognized in connection with the interest rate swaps. The remaining $5 million fair value adjustment at that date, will be amortized through interest expense over the period to maturity.
	During the three months ended June 30, 2013, the Company entered into two short-term treasury locks to hedge against the potential variability in benchmark interest rates in advance of the anticipated issuance of new senior notes. These were closed out during the three months ended September 30, 2013 following the issue of the new senior notes described in Note 16 — '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. 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, in 2013 the Company recognized a $2 million gain in interest expense for the portion of the treasury locks determined as ineffective.
	Foreign Currency Risk
	The Company’s primary foreign exchange risks arise from the following:
	•	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
	•	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 Pounds sterling expenses exceed Pounds 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 while 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 September 30, 2014 and December 31, 2013, the Company’s foreign currency contracts were all designated as hedging instruments except 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.
		Sell				Fair value
		(millions)
	US dollar	$	503			$	3
	Euro	176				12
	Japanese yen	54				5
	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 September 30, 2014 and December 31, 2013 were immaterial.
	During the nine months ended September 30, 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 $350 million (December 31, 2013: $228 million). In respect of these transactions, $16 million has been recognized as an asset within other current assets and an equivalent gain has been recognized in other expense (income), net, for the period.
	In addition during the three months ended September 30, 2014, in order to hedge the Company’s exposure relating to the purchase price consideration for acquiring an approximate 75 percent holding in Max Matthiessen AB, the Company entered into a series of forward exchange contracts. As a result of these transactions we have recognized a $14 million loss, in other expense (income), net, and an equivalent reduction to cash and cash equivalents in the period.

(i) 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 rates 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, changes in fair value attributable to movement in the forward points are also included.
At September 30, 2014, the Company estimates there will be $17 million of net derivative gains reclassified from accumulated comprehensive income into earnings within the next twelve months as the forecasted transactions affect earnings.
Fair Value Hedges
The Company had previously designated interest rate swaps as fair value hedges against its $350 million 5.625% senior notes due 2015 and 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.
All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.
The table below presents the effects of derivative financial instruments no longer in fair value hedging relationships on the consolidated statements of operations for the three and nine months ended September 30, 2014 and 2013.

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, 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 September 30, 2014.

FAIR VALUE MEASUREMENT	'
	FAIR VALUE MEASUREMENT
	The Company has categorized its assets and liabilities that are measured at fair value on a 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 the fair value hedge - Fair values are based on quoted market values and are therefore 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.
	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.

Goodwill and Intangible Assets Disclosure [Abstract]	'
GOODWILL	'
	GOODWILL
	Goodwill represents the excess of the cost of businesses acquired over the fair market 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 relative fair value of that entity compared with the fair value of the reporting unit in which it is included.
	The changes in the carrying amount of goodwill by segment for the nine months ended September 30, 2014 and the year ended December 31, 2013 are as follows:

	Term loans and revolving credit facilities
	On July 23, 2013, the Company entered into an amendment to its existing credit facilities (the term loan and revolving credit facility) to extend both the amount of financing and the maturity date of the facilities. As a result of this amendment, our revolving credit facility was increased from $500 million to $800 million and the maturity date on the $300 million term loan and revolving credit facility was extended to July 23, 2018, from December 16, 2016. There was no increase to the amount outstanding on the term loan as a result of this amendment.
	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.
	Drawings under the $800 million revolving credit facility bear interest at LIBOR plus 1.50% and the facility expires on July 23, 2018. These margins apply while the Company’s debt rating remains BBB-/Baa3. As of September 30, 2014 $nil was outstanding under this revolving credit facility.
	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 September 30, 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 shall 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 three months ended September 30, 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.

Segment Reporting [Abstract]	'
SEGMENT INFORMATION	'
	SEGMENT INFORMATION
	During the periods presented, the Company operated through three 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, and access to Global’s specialist expertise when required.
	Effective January 1, 2014, the Company has changed its internal reporting structure and the financial information used to evaluate performance and support decision making. The 2013 comparatives have been retrospectively reclassified to take into account these changes.
	As a result of these changes:
	•	the UK retail business, previously reported within the International reporting segment, has been combined with our Specialty businesses and is now reported within the Global reporting segment;
	•	the Mexican retail business, previously reported within the North America reporting segment, is now reported within the International reporting segment; and
	•	the US captive consulting business and facultative reinsurance businesses, both previously reported within the North America reporting segment, are now reported within the Global reporting segment.
	In addition to these structural changes, operating income used to evaluate performance and support decision making has changed to reflect the following: amortization of intangibles, which was previously excluded from segmental expenses, is now reported in operating expenses for each of the reporting segments; certain leadership, project, and other costs relating to Group functions which were previously allocated in full to the reporting segments are now retained in Corporate and other; and the non-servicing elements of the defined benefit pension schemes cost (income), which were previously included within operating expenses of the reporting segments are now retained within Corporate and other.
	For internal reporting and segmental reporting, the following items for which segmental management are not held accountable are excluded from segmental expenses:
	(i)	costs of the holding company;
	(ii)	costs of Group functions, leadership and projects;
	(iii)	significant legal and regulatory settlements which are managed centrally;
	(iv)	non-servicing elements of the defined benefit pension schemes cost (income);
	(v)	fees related to the extinguishment of debt;
	(vi)	some of the costs associated with the Operational Improvement Program; and
	(vii)	costs associated with the 2013 Expense Reduction Initiative.
	The accounting policies of the segments are consistent with those described in Note 2 — ‘Basis of Presentation and Significant Accounting Policies’ to the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	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.

	FINANCIAL INFORMATION FOR PARENT GUARANTOR, OTHER GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES
	Willis North America Inc. (‘Willis North America’) has $148 million senior notes outstanding that were issued on July 1, 2005, $394 million of senior notes issued on March 28, 2007 and $187 million of senior notes issued on September 29, 2009.
	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, Trinity Acquisition Limited (previously registered as Trinity Acquisition plc) and Willis Group Limited, collectively the ‘Other Guarantors’, and with Willis Group Holdings, the ‘Guarantor Companies’.
	The debt securities that were issued by Willis North America and guaranteed by the entities described above, and for which the disclosures set forth below relate and are required under applicable SEC rules, were issued under an effective registration statement.
	The guarantee of the guarantors will be deemed to be automatically discharged and released in accordance with the terms of the indenture upon release or discharge of the indebtedness or upon sale of the subsidiary or its assets.
	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 and are all direct or indirect parents of the issuer;
	(iii)	the Issuer, Willis North America;
	(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 unaudited condensed consolidating balance sheets as of September 30, 2014 of Willis Group Holdings, the Other Guarantors and the Issuer.
	The entities included in the Other Guarantors column as of September 30, 2014 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, TA I Limited, Trinity Acquisition Limited and Willis Group Limited.
	Restatement to 2013 financial information
	Regulation S-X, Article 3, Rule 3-10, allows for the presentation of condensed consolidating financial information. In accordance with these rules, the condensed consolidating financial information should be presented in accordance with US GAAP, except that (i) the guarantor and non-guarantor information is presented on a combined rather than consolidated basis, which requires the elimination of intra-entity activity and (ii) investments in subsidiaries are required to be presented under the equity method of accounting. Subsequent to the issuance of our financial statements for the third quarter 2013, management determined that certain balances were not presented in accordance with the above principles and have therefore restated our condensed consolidating financial information to reflect (i) gross, rather than net, presentation of intercompany balance sheet positions; (ii) dividends received from subsidiaries as reductions to the equity method investment balances as opposed to component of investment income from group undertakings; and (iii) appropriate push down accounting for goodwill.
	The impacts of these changes on the previously reported 2013 financial statements are shown in the tables below.

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.
The guarantee of the guarantors will be deemed to be automatically discharged and released in accordance with the terms of the indenture upon release or discharge of the indebtedness or upon sale of the subsidiary or its assets.
The condensed consolidating financial information for the following entities is presented below:
(i)Willis Group Holdings, which is a guarantor, on a parent company only basis;
(ii)	the Other Guarantors, which are wholly owned subsidiaries (directly or indirectly) of the parent. Willis Netherlands B.V, Willis Investment UK Holdings Limited, and TA 1 Limited are all direct or indirect parents of the issuer, and Willis Group Limited and Willis North America, Inc are direct or indirect wholly owned subsidiaries of 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 as of September 30, 2014 of Willis Group Holdings, the Other Guarantors, and the Issuer.
The entities included in the Other Guarantors column as of September 30, 2014 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, Willis North America, TA I Limited, and Willis Group Limited.
Restatement to 2013 financial information
Regulation S-X, Article 3, Rule 3-10, allows for the presentation of condensed consolidating financial information. In accordance with these rules, the condensed consolidating financial information should be presented in accordance with US GAAP, except that (i) the guarantor and non-guarantor information is presented on a combined rather than consolidated basis, which requires the elimination of intra-entity activity and (ii) investments in subsidiaries are required to be presented under the equity method of accounting. Subsequent to the issuance of our financial statements for the third quarter 2013, management determined that certain balances were not presented in accordance with the above principles and have therefore restated our condensed consolidating financial information to reflect (i) gross, rather than net, presentation of intercompany balance sheet positions, (ii) dividends received from subsidiaries as reductions to the equity method investment balances as opposed to component of investment income from group undertakings, and (iii) appropriate push down accounting for goodwill.
The impacts of these changes on the previously reported 2013 financial statements are shown in the tables below.

FINANCIAL INFORMATION FOR PARENT ISSUER, GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES	9 Months Ended
	Sep. 30, 2014
Condensed Financial Information of Parent Company Only Disclosure [Abstract]	'
FINANCIAL INFORMATION FOR PARENT ISSUER, GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES	'
	23	FINANCIAL INFORMATION FOR PARENT ISSUER, GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES
	On March 17, 2011, the Company issued senior notes totaling $800 million in a registered public offering. These debt securities are issued by Willis Group Holdings (‘Holdings Debt Securities’) and are guaranteed by certain of the Company’s subsidiaries. Therefore, the Company is providing the unaudited condensed consolidating financial information below. The following wholly owned subsidiaries (directly or indirectly) 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 unaudited condensed consolidating financial information is presented in Note 22) in that Willis Group Holdings is the Parent Issuer and Willis North America is a subsidiary guarantor.
	The guarantee of the guarantors will be deemed to be automatically discharged and released in accordance with the terms of the indenture upon release or discharge of the indebtedness or upon sale of the subsidiary or its assets.
	The condensed consolidating financial information for the following entities is presented below:
	(i)	Willis Group Holdings, which is the Parent Issuer;
	(ii)	the Guarantors, which are wholly owned subsidiaries (directly or indirectly) 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 unaudited condensed consolidating balance sheets as of September 30, 2014 of Willis Group Holdings and the Guarantors.
	The entities included in the Guarantors column as of September 30, 2014 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, TA I Limited, Trinity Acquisition Limited, Willis Group Limited, and Willis North America.
	Restatement to 2013 financial information
	Regulation S-X, Article 3, Rule 3-10, allows for the presentation of condensed consolidating financial information. In accordance with these rules, the condensed consolidating financial information should be presented in accordance with US GAAP, except that (i) the guarantor and non-guarantor information is presented on a combined rather than consolidated basis, which requires the elimination of intra-entity activity and (ii) investments in subsidiaries are required to be presented under the equity method of accounting. Subsequent to the issuance of our financial statements for the third quarter 2013, management determined that certain balances were not presented in accordance with the above principles and have therefore restated our condensed consolidating financial information to reflect (i) gross, rather than net, presentation of intercompany balance sheet positions, (ii) dividends received from subsidiaries as reductions to the equity method investment balances as opposed to component of investment income from group undertakings, and (iii) appropriate push down accounting for goodwill.
	The impacts of these changes on the previously reported 2013 financial statements are shown in the tables below.

	FINANCIAL INFORMATION FOR PARENT GUARANTOR, OTHER GUARANTOR SUBSIDIARIES AND NON-GUARANTOR SUBSIDIARIES
	Willis North America Inc. (‘Willis North America’) has $148 million senior notes outstanding that were issued on July 1, 2005, $394 million of senior notes issued on March 28, 2007 and $187 million of senior notes issued on September 29, 2009.
	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, Trinity Acquisition Limited (previously registered as Trinity Acquisition plc) and Willis Group Limited, collectively the ‘Other Guarantors’, and with Willis Group Holdings, the ‘Guarantor Companies’.
	The debt securities that were issued by Willis North America and guaranteed by the entities described above, and for which the disclosures set forth below relate and are required under applicable SEC rules, were issued under an effective registration statement.
	The guarantee of the guarantors will be deemed to be automatically discharged and released in accordance with the terms of the indenture upon release or discharge of the indebtedness or upon sale of the subsidiary or its assets.
	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 and are all direct or indirect parents of the issuer;
	(iii)	the Issuer, Willis North America;
	(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 unaudited condensed consolidating balance sheets as of September 30, 2014 of Willis Group Holdings, the Other Guarantors and the Issuer.
	The entities included in the Other Guarantors column as of September 30, 2014 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, TA I Limited, Trinity Acquisition Limited and Willis Group Limited.
	Restatement to 2013 financial information
	Regulation S-X, Article 3, Rule 3-10, allows for the presentation of condensed consolidating financial information. In accordance with these rules, the condensed consolidating financial information should be presented in accordance with US GAAP, except that (i) the guarantor and non-guarantor information is presented on a combined rather than consolidated basis, which requires the elimination of intra-entity activity and (ii) investments in subsidiaries are required to be presented under the equity method of accounting. Subsequent to the issuance of our financial statements for the third quarter 2013, management determined that certain balances were not presented in accordance with the above principles and have therefore restated our condensed consolidating financial information to reflect (i) gross, rather than net, presentation of intercompany balance sheet positions; (ii) dividends received from subsidiaries as reductions to the equity method investment balances as opposed to component of investment income from group undertakings; and (iii) appropriate push down accounting for goodwill.
	The impacts of these changes on the previously reported 2013 financial statements are shown in the tables below.

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.
The guarantee of the guarantors will be deemed to be automatically discharged and released in accordance with the terms of the indenture upon release or discharge of the indebtedness or upon sale of the subsidiary or its assets.
The condensed consolidating financial information for the following entities is presented below:
(i)Willis Group Holdings, which is a guarantor, on a parent company only basis;
(ii)	the Other Guarantors, which are wholly owned subsidiaries (directly or indirectly) of the parent. Willis Netherlands B.V, Willis Investment UK Holdings Limited, and TA 1 Limited are all direct or indirect parents of the issuer, and Willis Group Limited and Willis North America, Inc are direct or indirect wholly owned subsidiaries of 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 as of September 30, 2014 of Willis Group Holdings, the Other Guarantors, and the Issuer.
The entities included in the Other Guarantors column as of September 30, 2014 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, Willis North America, TA I Limited, and Willis Group Limited.
Restatement to 2013 financial information
Regulation S-X, Article 3, Rule 3-10, allows for the presentation of condensed consolidating financial information. In accordance with these rules, the condensed consolidating financial information should be presented in accordance with US GAAP, except that (i) the guarantor and non-guarantor information is presented on a combined rather than consolidated basis, which requires the elimination of intra-entity activity and (ii) investments in subsidiaries are required to be presented under the equity method of accounting. Subsequent to the issuance of our financial statements for the third quarter 2013, management determined that certain balances were not presented in accordance with the above principles and have therefore restated our condensed consolidating financial information to reflect (i) gross, rather than net, presentation of intercompany balance sheet positions, (ii) dividends received from subsidiaries as reductions to the equity method investment balances as opposed to component of investment income from group undertakings, and (iii) appropriate push down accounting for goodwill.
The impacts of these changes on the previously reported 2013 financial statements are shown in the tables below.
