Here's a link to their Q3 report (opens as a pdf): http://www.kinnevik.se/Documents/Pdf/Pressreleases/en/394278.pdf
What I liked most was the ability to buy Millicom at a significant discount (admittedly, it makes MICC less of a pure play). MICC is growing nicely in LatAm and Africa, just bought back 10% debt, and is growing FCF.
When added to MICC (~44% of NAV), other listed holdings make up about 90% of KINVB's NAV, so it's a pretty transparent valuation model. The remaining 10% is a pulp/paper/containerboard business (there is operational risk for management) and venture.
The venture portion is particularly interesting, although I'm not sure it will really move the NAV needle (for what it's worth, they have an indirect position in Groupon, which is a big deal here in Silicon Valley, but will it make a difference?). That said, they have agriculture investments in eastern Europe and Russia, microfinance in India and Peru, private equity in Africa, and internet businesses in Europe. I view these odds and ends as the "alternative investments" part of the overall portfolio.
