某公司的有关资料如下： (1)息税前利润为1000万元。 (2)所得税税率为33%。 (3)长期负债400万元，均为长期债券，平均利息率10%。 (4)发行股数60万股(每股面值1元)，每股账面价值10元，当前市价32.5元。 (5)公司暂时没有累积留存收益。 该公司产品市场前景看好，预期今后每年增长6%，所有净利润的40%用于发放股利，并假定股票价格与其内在价值相等。 要求： (1)计算该公司每股收益及普通股成本。 (2)计算该公司的加权平均资本成本。 (3)该公司可以增加400万元的负债，使负债总额为800万元，以便在现行价格下购回股票。假定此项举措将使负债平均利息率上升至11.5%，普通股权益成本提高到22%，税息前利润保持不变。如果以股价高低判别，试问该公司应否改变其资本结构。 (4)计算该公司资本结构改变前后的已获利息倍数。
