One of the major risks of relying on dividend income, is the potential for a company to struggle financially and cut its dividend. Not only is your income cut, but the value of your investment declines as well - nasty. The first recorded dividend for EnerSys, in the last decade, was eight years ago. Its dividend has not fluctuated much that time, which we like, but we're conscious that the company might not yet have a track record of maintaining dividends in all economic conditions. During the past eight-year period, the first annual payment was US$0.5 in 2013, compared to US$0.7 last year. Dividends per share have grown at approximately 4.3% per year over this time.
