 However, the proportion of preferred and capital shares does not necessarily have to be one-to-one.Reducing the ratio of issued preferred shares to capital shares (e.g., one preferred share for every two capital shares) would reduce the risk and safely support higher yield for the preferred shares at the cost of making the capital shares less attractive to investors due to increased risk, lower sustainable yield payout and smaller capital gain leverage.The dividend income from the underlying shares may be insufficient to pay out the dividend income for both the preferred and capital shares.
