Carillion

{{main|Tarmac Group}}

Carillion was created in July 1999, following a demerger from Tarmac, which had been founded in 1903. Tarmac focused on its core heavy building materials business, while Carillion included the former Tarmac Construction contracting business and the Tarmac Professional Services group of businesses.{{cite news |url=http://news.bbc.co.uk/1/hi/business/the_company_file/297579.stm |title=Tarmac to split in two |work=BBC News |date=16 March 1999 |access-date=13 July 2008 |archive-url=https://web.archive.org/web/20030407034938/http://news.bbc.co.uk/1/hi/business/the_company_file/297579.stm |url-status=bot: unknown |archive-date=7 April 2003 }} At the time of demerger Sir Neville Simms was appointed executive chairman of the business.{{cite news |url=https://www.theguardian.com/business/1999/jul/02/12 |title=Tarmac investors threaten revolt |first=Lisa |last=Buckingham |newspaper=The Guardian |date=2 July 1999 |access-date=21 February 2018 |archive-url=https://web.archive.org/web/20140507190733/https://www.theguardian.com/business/1999/jul/02/12 |url-status=live |archive-date=7 May 2014}} Simms stood down from his executive responsibilities in January 2001 but remained non-executive chairman until May 2005 when Philip Rogerson took over the chair.{{cite web |url=https://www.bloomberg.com/research/stocks/people/person.asp?personId=1793256&privcapId=410348 |title=Philip Graham Rogerson |website=Bloomberg |access-date=17 April 2016 |url-access=limited |url-status=live |archive-url=https://web.archive.org/web/20190701215337/https://www.bloomberg.com/research/stocks/people/person.asp?personId=1793256&privcapId=410348 |archive-date=1 July 2019}}

The name 'Carillion', a corruption of the word 'carillon' (a peal of bells), was intended to give the construction business a clearly defined, separate identity, and to distance it from its construction roots.{{cite news |last1=Minton |first1=Anna |title=Tarmac spins off construction arm as Carillion |url=https://www.independent.co.uk/news/business/tarmac-spins-off-construction-arm-as-carillion-1100147.html |access-date=19 January 2018 |newspaper=The Independent |date=13 June 1999 |url-status=live |archive-url=https://web.archive.org/web/20180115191649/https://www.independent.co.uk/news/business/tarmac-spins-off-construction-arm-as-carillion-1100147.html |archive-date=15 January 2018}} It was proposed by London branding consultancy Sampson Tyrell (later Enterprise IG,{{cite news |last1=Taylor |first1=David |title='Where did they get the Carillion name?

In August 2014, the company spent several weeks attempting a merger with rival Balfour Beatty. Three offers were made; the last bid, which valued Balfour Beatty at £2.1 billion, was unanimously rejected by the Balfour Beatty board on 19 August 2014. Balfour refused to allow an extension of time for negotiations that could have prompted a fourth bid. Carillion announced later that day that it would no longer pursue a merger with its rival.{{cite news |title=Balfour Beatty rejects latest Carillion merger offer |url=https://www.theguardian.com/business/2014/aug/20/balfour-beatty-rejects-latest-carillion-merger-offer |date=20 August 2014 |access-date=21 August 2014 |work=The Guardian |first=Jennifer |last=Rankin |url-status=bot: unknown |archive-url=https://web.archive.org/web/20140820195623/http://www.theguardian.com/business/2014/aug/20/balfour-beatty-rejects-latest-carillion-merger-offer |archive-date=20 August 2014 }}

In 2009, Carillion was revealed as a subscriber to an illegal construction industry blacklisting body, The Consulting Association (TCA), though its inclusion on the list was mainly due to its previous ownership of Crown House Engineering (acquired by Laing O'Rourke in 2004), and previous use of TCA by Mowlem (acquired by Carillion in 2006).

A delayed National Audit Office report into the government's handling of the Midland Metropolitan and Royal Liverpool hospitals was published in January 2020. The report warned of possible further significant cost increases, particularly to rectify the badly built Liverpool project, and blamed Carillion for pricing the jobs too low to meet specifications. The two projects were expected to cost more than 40% more than their original budgets, and to be completed between three and five years late. However, due to effective risk transfer to the contractor, the total cost to the taxpayer would be very similar to the original plan.{{cite news |last1=Morby |first1=Aaron |title=NAO raises alarm over cost of finishing Carillion hospitals |url=https://www.constructionenquirer.com/2020/01/17/nao-raises-alarm-over-cost-of-finishing-carillion-hospitals/ |access-date=17 January 2020 |work=Construction Enquirer |date=17 January 2020 |archive-url=https://web.archive.org/web/20200512104542/https://www.constructionenquirer.com/2020/01/17/nao-raises-alarm-over-cost-of-finishing-carillion-hospitals/ |archive-date=12 May 2020 |url-status=live}} A follow-up investigation into the hospitals projects by the Public Accounts Committee was postponed in May 2020 due to the COVID-19 pandemic in the United Kingdom.{{cite news |last1=Marshall |first1=Jordan |title=Government probe into Carillion hospital jobs suspended because of pandemic |url=https://www.building.co.uk/news/government-probe-into-carillion-hospital-jobs-suspended-because-of-pandemic/5106205.article |access-date=28 May 2020 |work=Building |date=28 May 2020 |url-access=registration |archive-url=https://web.archive.org/web/20200620034137/https://www.building.co.uk/news/government-probe-into-carillion-hospital-jobs-suspended-because-of-pandemic/5106205.article |archive-date=20 June 2020 |url-status=live}}

The company's liquidation raised political questions about the award of UK Government contracts to a financially troubled business, and about Private Finance Initiative projects and wider privatisation of public services.

Its opening paragraph summarised the committees' views:

Carillion’s rise and spectacular fall was a story of recklessness, hubris and greed. Its business model was a relentless dash for cash, driven by acquisitions, rising debt, expansion into new markets and exploitation of suppliers. It presented accounts that misrepresented the reality of the business, and increased its dividend every year, come what may. Long term obligations, such as adequately funding its pension schemes, were treated with contempt. Even as the company very publicly began to unravel, the board was concerned with increasing and protecting generous executive bonuses. Carillion was unsustainable. The mystery is not that it collapsed, but that it lasted so long.{{cite book|title=Carillion: Second Joint report from the Business, Energy and Industrial Strategy and Work and Pensions Committees of Session 2017–19|url=https://publications.parliament.uk/pa/cm201719/cmselect/cmworpen/769/769.pdf|date=2018|publisher=House of Commons|location=London|page=3|access-date=16 May 2018}}

The report said Carillion's collapse had significant consequences, citing: over 2,000 job losses; a pension liability of around £2.6 billion reducing payments to 27,000 pension scheme members; debts owed to 30,000 suppliers, sub-contractors and other creditors; and £150M in UK Government expenditure to keep essential public services running. Former directors Philip Green, Richard Adam and Richard Howson were singled out for particular criticism. The select committee chairs (Frank Field and Rachel Reeves) called for a complete overhaul of Britain's corporate governance regime, saying the government had "lacked the decisiveness or bravery" to do so, and accused the big four accounting firms of operating as a "cosy club", with KPMG singled out for its "complicity" in signing off Carillion's "increasingly fantastical figures" and internal auditor Deloitte accused of failing to identify, or ignoring, "terminal failings". The report recommended the Government refer the statutory audit market to the Competition and Markets Authority, urging consideration of breaking up the Big Four, while two regulators, the Financial Reporting Council and The Pensions Regulator, were branded as "chronically passive".

In light of the MPs' criticism, The Pensions Regulator's CEO Lesley Titcomb announced she would step down at the end of her four-year term in February 2019.{{cite news |last1=Curry |first1=Rhianon |title=The Pensions Regulator head to step down |url=https://www.telegraph.co.uk/business/2018/05/31/pensions-regulator-head-step/ |access-date=4 June 2018 |work=Telegraph |date=31 May 2018}} On 25 June 2018, TPR announced it was considering issuing a contribution notice – a legally enforceable demand for a financial contribution to the pension deficit – against former Carillion directors.{{cite web |title=TPR could go after Carillion's former directors "for everything they've got" |url=https://www.parliament.uk/business/committees/committees-a-z/commons-select/work-and-pensions-committee/news-parliament-2017/chairs-comment-tpr-investigation-carillion-17-19/ |website=www.parliament.uk |publisher=Work and Pensions select committee |access-date=26 June 2018}}{{cite news |last1=Morby |first1=Aaron |title=Carillion bosses could be landed with pension bill |url=http://www.constructionenquirer.com/2018/06/25/carillion-bosses-could-be-landed-with-pension-bill/ |access-date=26 June 2018 |work=Construction Enquirer |date=25 June 2018}}

The parliamentary inquiry was criticised for lacking objectivity and thoroughness, treating a highly complex situation in an incomplete manner. In published letters to the committees, ex-Carillion CEO Howson contended that Carillion was a victim of its public sector clients and that "any analysis as to the causes of the failure of Carillion is not complete without looking at the way in which government and the wider public sector procured services from Carillion and failed to administer payments."{{cite news|last1=Howson|first1=Richard|title=What the MPs Missed|url=https://www.theconstructionindex.co.uk/news/view/what-the-mps-missed-by-richard-howson|access-date=12 July 2018|work=The Construction Index|date=12 July 2018}}

The committees chairs were critical of Carillion's directors continued denials that they were to blame, and concerned at the lack of "meaningful competition" in the audit market; Rachel Reeves, chair of the Business, Energy and Industrial Strategy Committee ("BEIS committee"), said: "The CMA needs to closely examine the audit market and as a Committee we will be keen to see what remedies are proposed to fix the broken audit market."{{cite news |title=Carillion next steps: Committees publish interested parties' responses |url=https://www.parliament.uk/business/committees/committees-a-z/commons-select/work-and-pensions-committee/news-parliament-2017/carillion-report-responses-published-17-19/ |access-date=13 July 2018 |work=Parliament.UK: Work and Pensions Committee |date=12 July 2018}} In September 2018, Business Secretary Greg Clark announced he had asked the CMA to conduct an inquiry into competition in the audit sector,{{cite news |last1=Busby |first1=Mattha |title=Audit sector faces inquiry as minister points to deficiencies |url=https://www.theguardian.com/business/2018/sep/29/uk-mulls-audit-sector-reform-after-minister-admits-deficiencies |access-date=29 September 2018 |work=Guardian |date=29 September 2018}} which was launched in October{{cite web |title=CMA launches immediate review of audit sector |url=https://www.gov.uk/government/news/cma-launches-immediate-review-of-audit-sector |website=Gov.uk |access-date=9 October 2018}} and reported in December 2018.

Carillion had been downgraded to red following its July 2017 profit warning; when officials recommended a provisional black rating in November 2017, Carillion bosses persuaded them not to.{{cite news|last1=Prior|first1=Grant|title=Government slammed for not spotting Carillion was in trouble|url=http://www.constructionenquirer.com/2018/05/23/government-slammed-for-not-spotting-carillion-was-in-trouble/|access-date=23 May 2018|work=Construction Enquirer|date=23 May 2018}} Like the Business and the Work and Pensions Select Committees, the PAC called for a Cabinet Office review of the roles of crown representatives after they failed to spot Carillion's perilous state.{{cite news |last1=Smulian |first1=Mark |title=Cabinet Office urged to review crown representative role after Carillion failings |url=https://www.civilserviceworld.com/articles/news/cabinet-office-urged-review-crown-representative-role-after-carillion-failings |access-date=1 June 2018 |work=Civil Service World |date=31 May 2018}} In September 2018, after receiving a "complacent" Cabinet Office response to the Business and the Work and Pensions Select Committees recommendations regarding crown representatives, Frank Field said: "The picture the Cabinet Secretary paints of our Crown Representatives is more Johnny English than James Bond, instilling little confidence in their ability or capacity to defend the public interest in the multi-billion pound world of Government outsourcing."{{cite web |title=Crown Reps "more Johnny English than James Bond" |url=https://www.parliament.uk/business/committees/committees-a-z/commons-select/work-and-pensions-committee/news-parliament-2017/carillion-government-response-17-19/ |website=Parliament.uk |publisher=Commons Select Committee |access-date=14 September 2018}}

As a result, it said public services had deteriorated.{{cite news |last1=Wearden |first1=Graeme |title=Carillion collapse exposed government outsourcing flaws – report |url=https://www.theguardian.com/business/2018/jul/09/carillion-collapse-exposed-government-outsourcing-flaws-report |access-date=9 July 2018 |work=Guardian |date=9 July 2018}} Responding to the PCAC report, the UK government admitted "Carillion’s liquidation has exposed issues that have at times informed a breakdown of trust between government, suppliers and the public."{{cite news |title=Government Response to the Committee's Seventh Report: After Carillion: Public sector outsourcing and contracting |url=https://publications.parliament.uk/pa/cm201719/cmselect/cmpubadm/1685/168502.htm |access-date=5 November 2018 |work=Public Administration Committee |date=5 November 2018}} The Cabinet Office, in its PCAC response, said it would require suppliers to reveal more information about their financial health; Whitehall would monitor up to five key performance indicators (KPIs) of major contracts with external suppliers.{{cite news |last1=Johnstone |first1=Richard |last2=Trendall |first2=Sam |title=Government database to track KPIs of top contracts in post-Carillion shake-up |url=https://www.publictechnology.net/articles/news/government-database-track-kpis-top-contracts-post-carillion-shake |access-date=7 November 2018 |work=Public Technology |date=7 November 2018}}

In June 2018, the National Audit Office published its investigation into the collapse of Carillion, criticising the government for not spotting financial problems at a key supplier sooner.

The chairs of the Parliamentary select committees enquiry, Frank Field and Rachel Reeves responded to the NAO report. Field said Carillion had "hoodwinked" the government and viewed PwC's involvement in managing the liquidation as a potential conflict of interest.
