During the month, base metals fell with copper, zinc, nickel and aluminium down -0.7%, -2.1%, -7.1% and -10.1% respectively. Iron ore was a bright spot amidst the bulk commodities as it increased by +2.0%, whilst thermal coal and steel fell -5.4% and -5.9%. (Source: Thomson Reuters Datastream) Across the commodity complex the oil price was the weakest performer declining -22.2% (Brent) and -18.9% (WTI). Mining companies with energy components to their business, such as BHP Billiton, Freeport McMoRan and Vedanta, were particularly affected during the month as a result of this commodity price weakness. Despite the brief respite felt by the iron ore price in December, the iron ore producers continued to feel the pressure, particularly Vale and Fortescue. Over the course of 2014, the iron ore price declined -46.9%. Precious metals performed relatively well during the month: gold was broadly flat at +0.4%, whilst silver, platinum and palladium returned +1.0%, +0.1% and +0.3% respectively. The yellow metal saw some support in early December as the US dollar strength eased and a sharp depreciation of the Russian rouble led the central bank to increase interest rates to 17%, leaving a sense of unease in the market. Gold saw some safe-haven bids as uncertainty intensified, but volumes were relatively modest and this early strength was reversed later in the month when the release of lower than expected US inflation data put downward pressure on the price. Following the month end, Banro Corporation released their Q4 production results to the market, as well as providing an update on their financing situation. Operationally, the company had its best ever quarterly production result at 38,236 ounces of gold, the second quarter in a row of improvement illustrating that the action taken earlier in the year is now delivering results. The company informed the market that the previously announced financing transaction has been delayed and that closing of the deal was on "a more extended timeline" than originally anticipated. As a result, they are progressing with alternative sources of funding but did confirm they have elected to accrue the dividend related to the gold-linked preference shares held by the Company. As stated in the Company's November monthly announcement (released 11 December 2014), the gold-linked preference shares are held at a 30% discount to the implied gold price and the corporate bond at a 25% discount to the last traded price on 21 November 2014 (as per Bloomberg). As at the end of December 2014, the total exposure to Banro was 2.8% of the NAV, of which the corporate bond represents 1.0% and the gold-linked preference shares represent 1.8%. Strategy / Outlook The mining sector has significantly lagged the general equity market in recent years. However, a number of the downside risks that led to this underperformance have reduced (albeit not disappeared). The industry has made good progress in refocusing its strategy: operating costs have been aggressively targeted and investment in projects reassessed. Given the recent falls in commodity prices, we acknowledge that this could take longer to come through than we would have expected six months ago. Recent commodity price moves are likely to abate some of the expected improvement in free cash flow within the sector and are prompting earnings downgrades. However, many commodities are trading close to or below their marginal cost of production, implying that price downside should be limited, in the absence of a collapse in demand.
