The median is the middle company: half report more and half report less. Each median covers only the companies that reported that figure, so it describes those companies and not every company in the industry. A median is shown only when at least 30 companies reported the figure.

13,156 of the 24,088 companies with net assets for two consecutive years (54.6%) reported higher net assets than the year before.
