This steady performer has been paying dividends for more than 60 years. RGC's earnings rose 3% from one year earlier to $4.65 million, or $1.01 per share in the fiscal year ended Sept.30 . This was mainly the result of increased natural-gas deliveries to industrial customers and a recent service rate increase. In late November, RGC raised the dividend by 3% to a $0.70 annual rate. The new dividend rate will be paid on Feb.1, 2012, to shareholders of record on Jan.16, 2012.
