Earlier in the day, Washington Mutual became the latest casualty of mortgage market turbulence. The shares of the savings and loan slid after it said it would cut its dividend, eliminate thousands of jobs and raise $2.5 billion in new capital. WaMu, whose shares lost 12.4 percent to $17.42, said it sees losses from mortgages increasing in 2008.

请问1、The shares of the savings and loan是什么意思？是存贷股票？好像不通。2、
it sees losses from mortgages increasing in 2008.是什么意思？

1 储款和贷款的份额
2 2008年它于抵押增长中预见到损失。
