Commenting on the results, Partner and Portfolio Manager George Ensor said:

"Sentiment towards UK listed small and micro cap companies remains depressed and at odds with the ongoing improvement in company fundamentals and earnings. We currently have a portfolio of companies that have, in aggregate, grown earnings rapidly over the last few years, with net cash balance sheets and substantial free cash flow generation. The portfolio free cash flow yield is currently 7% which moves up to 8.5% when adjusted for the large discount to NAV that our shares currently trade at (17%) - a discount that is at odds with our peer group despite a track record and commitment to only retire equity.  We believe we are at or close to the start of a new global cycle of outperformance for smaller companies which is an environment in which this strategy will flourish."
