An analyst does research about preference shares. Which of the following statements is least likely to describe an attribution of participating preference shares Shareholders:（）
A. are entitled to an additional distribution of the company's assets upon liquidation, above the par (or face) value of the preference shares.
B. receive unpaid dividends in full before dividends on common shares can be paid.
C. receive the standard preferred dividends plus the opportunity to receive an additional. dividends when the company's profits exceed a pre-specified level.
参考答案：B
解析：
对于参与型优先股(participating preferred shares)，股东除了收到标准的股利外，还要加上当公司的利润超过某个设定的水平后额外增加的股利，同时股东可以在公司资产清算时就超过优先股面值的部分得到额外的分配。对于累积优先股(cumulative preferred share)，股东会要求公司把以前没付的优先股股利先付掉，再给付其当年的普通股分红。所以选项B并不是参与型优先股的特征。
