Exhibit 99.1

June 15, 2017

My fellow shareholders,

At our most recent meeting, the Board of Directors declared a dividend to be paid on or about June 15, 2017 to shareholders of record as of May 31, 2017. Your dividend check for 50 cents per share is enclosed.

Last year, the Board of Directors adopted a policy to declare and pay dividends, if any, on an annual basis rather than semi-annually or quarterly, as in past years. We anticipate this will reduce the administrative costs associated with the dividend payment process. If declared, future dividends are expected to be paid once a year – shortly after the Annual General Meeting. To date, we are pleased to announce that we have declared 64 consecutive dividends.

Our results for the quarter ended March 31, 2017 showed continued growth in revenue and net income.
