Competition commission has put the cat among the pigeons

Musical chairs for the audit market?

When the relationships between auditors and some listed companies can be measured in decades, with some spanning more than a century, the idea that companies should be forced to retender for audit services as often as every seven years is a bold suggestion indeed.

But this is what the UK’s Competition Commission (CC) has – albeit provisionally and with much further consultation to come before a final statement in the Autumn – suggested this morning, in what the CC’s audit group chair Laura Carstensen admits represents “some quite radical suggestions”.

The issue Carstensen’s group originally set out to address was the perception that extended relationships between businesses and their auditors breed a kind of familiarity that prevents shareholders’ interests from being protected when auditors run the rule over corporate accounts.

It stands to reason, after all, that an auditor with a longstanding rapport with the management of a business might be inclined to audit financial statements in a way more beneficial to the interests of that management team than to its shareholders.

To shake up this supposedly cosy state of affairs, the CC has proposed mandatory retendering and rotation of audit firms. This, in addition to the prohibition of "Big Four only" clauses in loan documentation, which restrict lending to companies audited by PwC, Ernst & Young, KPMG and Deloitte, and measures to increase engagement between auditors and shareholders.

On paper, mandatory rotation certainly looks like it would protect shareholder interests and increase competition, with smaller firms gaining audit market share from the Big Four, which currently take the lion’s share.

In practice, the concept invokes serious practical considerations that many, especially among the Big Four, think could be counterproductive to the quality of audit services.

First and foremost, mandatory rotation has cost implications to both auditors, who spend time and money on pitches to prospective clients, and those being audited. There are also setting-up costs for auditors and companies in new audit engagements.

Audit rotation after short periods also poses a threat to audit quality, particularly as engagements come to an end. Auditor rotation on a seven year basis is arguably ill-suited to large, complicated financial institutions whose inner workings require a long period for audit teams to understand.

In any case, audit firms already rotate engagement partners with clients to ensure independence, so it is not as if the profession has done nothing to address the issue of over-familiarity.  

But then again, this is exactly what consultation periods are for, and the CC itself acknowledges both the range of possible approaches to the rotation and retendering issue, seeking views on rotation periods of seven, ten and 14 years, and the fact that further recommendations would be contingent on responses to the current proposals.

Carstensen, speaking to me for International Accounting Bulletin this morning, said there is “evidence there is a price benefit to tendering, but we have to weigh up the costs and benefits – we want to know how we can find a point of equilibrium where the benefits are captured, but in such a way that it is not unduly costly or burdensome.”

There is plenty of time to find this point of equilibrium. This morning’s release only represents a summary of provisional findings, and the full text won’t be available until next week, with final recommendations to come in August at the earliest.

Nevertheless, they certainly represent a more aggressive stance to shaking up the market than many in the audit market had expected, and are likely to prompt a broader change in attitudes beyond the UK.

For some time the EU has been rumbling through its own debate on audit reform, and after making some fairly conservative recommendations towards the end of last year, has been widely regarded as waiting on what comes out of the CC before making further statements. Certainly, the CC’s suggestions on mandatory rotation are unambiguously more hard line than anything that has come out of Brussels.

Carstensen told me she expected today’s comments and future findings from the commission to have a definite impact on the continuing EU debate. “Brussels has a lot of respect for our process as very rigorous and very evidence based, and I would expect parties there to be very interested in what we conclude, and the basis on which we reach it.”

In this context, one wonders if the decision to start the rotation discussion at a benchmark of five to seven years was a move designed to bring more impassioned debate to a discussion that some perceived as having become quite flat. Whatever the intention, it has certainly had that effect.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
