LONDON -- Global mining giant BHP Billiton (LSE: BLT.L ) (NYSE: BBL ) is a business with very definite attractions. A £104 billion FTSE 100 (UKX) constituent, last year the company earned a pre-tax profit of $23 billion on revenues of $72 billion. (Note: yes, mixed currencies.)
And with margins like that, no wonder this defensively positioned business is popular with many investors. Better still, with its shares changing hands today at 1,948 pence, the company is rated on a price-to-earnings (P/E) ratio of 11, and offers income investors a forecast dividend yield of 3.9%.
But how safe is that share price? And -- of vital importance to income investors -- how safe is that dividend? In short, how could an investment in BHP Billiton adversely impact investors' wealth?
In this series, I set out to answer just these questions. My starting point: BHP Billiton's latest annual report, where the company's directors are obliged to address the issue of risk.
One immediate thing that I'm looking for is an acknowledgement that risks do exist, and that they need managing.
The good news? As you'd expect from a business of BHP Billiton's size and caliber, the company has in place a risk-management policy, a system of regular reviews and a number of high-level committees tasked with monitoring the risks that the business has identified.
But what, precisely, are those risks that the company faces?
Read the small print, and BHP Billiton identifies no fewer than 13 risks as having a significant prospective impact on the company's financial performance. They range from government and political engagement to climate change, and from a shift in currency exchange rates to commercial counter-party failure.
So let's take a look at three of the biggest.
Falling Chinese demand
The Chinese market has become a significant source of global demand for commodities. In 2011, notes BHP Billiton, China represented 61% of global seaborne iron ore demand, 39% of copper demand, 40% of nickel demand, 43% of aluminum demand, 48% of energy coal demand, and 10% of oil demand. The danger is obvious. As BHP Billiton itself puts it: "Sales into China generated $21.6 billion or 29.9 % of our revenue in the year ended 30 June 2012. A slowing in China's economic growth could result in lower prices and demand for our products, and negatively impact our results."
What can BHP Billiton do to counter this risk? Not a lot: What happens to the Chinese economy is very much out of its hands. But the company is clear that successful risk management can be a source of competitive advantage, and points to the carefully developed natural diversification in its portfolio of commodities, geographies, currencies, assets and liabilities as a key element in its risk management approach.
The commodity cycle
Fairly obviously, BHP Billiton is in the commodities business, which -- as most savvy investors recognize -- is subject to the commodity cycle, over which prices rise and fall as supply and demand fluctuate. As the company puts it: "The prices we obtain for our oil, gas, minerals and other commodities are determined by, or linked to, prices in world markets, which have historically been subject to substantial volatility. The ongoing uncertainty and impact on global economic growth, particularly in developed economies, may adversely affect future demand and prices for commodities."
Once again, what can BHP Billiton do about the commodity cycle? Nothing. But it can do its best -- as it has done -- to lock in long-term contracts and trading relationships, and spread its activities over as wide a set of commodities as is practicable, to avoid overexposure to the extremes of any one cycle.
Mining has an unarguable environmental impact. And there are also safety, health, and corporate social responsibility issues to throw in. Compliance today is a costly and complex business compared to the more relaxed standards of yesteryear, and there's little doubt that the regulatory regime is set to get tougher, not more lax. As BHP Billiton puts it: "The nature of the industries in which we operate means that many of our activities are highly regulated by health, safety and environmental laws. As regulatory standards and expectations are constantly developing, we may be exposed to increased litigation, compliance costs and unforeseen environmental rehabilitation expenses."
How is this risk dealt with? Routinely, BHP Billiton makes financial provisions for operational closure and site rehabilitation. In addition, it is aware that its employees face dangers and health risks from occupational exposure to noise, silica, manganese, diesel exhaust particulate, fluorides, coal tar pitch, nickel, and sulphuric acid mist, and does its best to minimize these.
Community actions are also targeted on fulfilling the company's corporate social responsibilities by providing skilled employment opportunities, decent salaries and wages, paying taxes and royalties, and community development programs, which include a commitment to invest 1% of pre‑tax profit in community programs.
On a dividend reinvested basis over the 15 years to Dec. 31, 2011, Neil Woodford delivered a return of 347%, versus the FTSE All-Share's distinctly more modest 42% performance. Warren Buffett, for his part, has delivered returns of over 20% per annum since 1965, transforming himself into the world's third-wealthiest person.
