Commenting on the markets, Richard Davis, representing the Investment Manager
noted:

November was a disappointing month for industrial and precious metals. Base
metals fell by 4.3%, with nickel tumbling by 7.6%. Copper was the best
performer, falling by 2.6% to US$3.20/lb. Copper's relative strength has been
underpinned by a steady fall in inventories since the summer. These now stand
at just 3.5 weeks' of supply. Gold prices slumped by 5.3% to US$1,253/oz, as
some positive US economic data fuelled speculation that the U.S. Federal
Reserve would look to "taper" as early as December. In energy markets, the
spread between Brent (the International benchmark) and West Texas Intermediate
(a US-centric price) widened. Brent gained 3.2% in November to close at
US$111.1/Bbl and WTI slipped by 3.9% to US$92.5/Bbl. Towards the end of the
month, significant progress was made in achieving a comprehensive resolution to
Iran's nuclear programme. While this is a significant political step, sanctions
on crude exports will be maintained for the time being so there is minimal
impact on cruse fundamentals in the near-term. If the political dialogue runs
smoothly, the sanctions may be lifted in 6 months' time. Brent prices were sold
off on the news, but quickly recovered. In Sterling terms, the mining shares
closed down by 6.9%, while the energy shares fell by 2.4%. Gold equities fell
by 14.1%.
