It has long been apparent to anyone with an ounce of business sense that, by and large, partnerships are not the best way to run a company. There are, naturally, exceptions and I am not going to take issue with the profitability of the ‘magic circle’ firms that would be eligible for inclusion in the FTSE100 were they to have publicly traded shares. They have all said, however, they would not seek to float. There are probably many reasons for this, most of which I couldn’t hope to understand. But I bet one of them is because the partners of those firms rather like being partners in those firms.
