Net rates of return for UK corporations have run strong in the last several quarters. The first quarter's outcome, 13.3%, was the third highest in the 16-year history of these quarterly data. These figures on corporate profitability were reported yesterday, July 5, by the UK Office of National Statistics and have just recently been added to Haver's UK database. The information, called "Profitability of UK Companies", is listed in both the Financial Data and National Accounts menus.

The rates of return are defined as the ratio of the net operating surplus to net capital employed. [The values in "gross" terms, i.e., before the deduction of capital consumption, are also published, but the "net" data get far more attention.] The factors in the ratio, net operating surplus and net capital employed, are published annually; rates of return are available quarterly for all private non-financial corporations and three categories: "Continental Shelf" companies, manufacturing firms and service sector companies. "Continental Shelf" refers to the UK petroleum industry.

In the first quarter, the 13.3% overall return represented a pick-up from the fourth quarter's 13.1% and was equal to the 2004 average of 13.3%. As might be expected, the Continental Shelf firms saw a boost in their return, to 29.6%, up from the prior quarter; the last five years have averaged 30.8%, the highest ever, with a range among individual quarters of 25.6%, right after 9/11, to 38.1% at the end of 2000.

Non-financial service industries experienced their strongest returns in the late 1990s. We'd speculate that computer software developers, internet companies and other tech firms led this high-profit time in the UK, when returns on capital peaked at 19.5% in the second quarter of 1998. The recent period, while lower, isn't "bad", with profitability still running at about 16.5% on average and this latest quarter at 17.5%.

Manufacturing returns have lagged. This has been so for a long time, throughout the history of these data back to 1970. The worst performance was during the energy "crisis"/stagflation recessions of the late 1970s and early 1980s, when, for instance, the net return dipped to just 1.5% in 1981. More currently, manufacturing firms saw good results from 1994 to 1999, but since then have fallen back to single-digits. The 6.0% in Q1 is among the lowest since the 1991 recession. The ONS suggests that the lower returns in manufacturing reflect their higher capital intensity, compared with service firms. This is certainly true, but perhaps their greater cyclicality and variability also restrain their overall performance.
