沃伦·巴菲特《伯克希尔·哈撒韦 1977 年致股东信》· 1977 Chairman's Letter · 投资
Operating earnings in 1977 of $21,904,000, or $22.54 per share, were moderately better than anticipated a year ago. Of these earnings, $1.43 per share resulted from substantial realized capital gains by Blue Chip Stamps which, to the extent of our proportional interest in that company, are included in our operating earnings figure. Capital gains or losses realized directly by Berkshire Hathaway Inc. or its insurance subsidiaries are not included in our calculation of operating earnings. While too much attention should not be paid to the figure for any single year, over the longer term the record regarding aggregate capital gains or losses obviously is of significance.

We expect difficulty in matching our 1977 rate of return during the forthcoming year. Beginning equity capital is up 23% from a year ago, and we expect the trend of insurance underwriting profit margins to turn down well before the end of the year. Nevertheless, we expect a reasonably good year and our present estimate, subject to the usual caveats regarding the frailties of forecasts, is that operating earnings will improve somewhat on a per share basis during 1978.
