谁能告诉我这句话的主谓宾？

Just as bosses and boards have finally sorted out their worst accounting and compliance troubles,and improved their feeble corporation governance ,----这是状语部分
a new problem主语threatens 谓语to earn them---这是句子的主干
-especially in America-这是插入语
the sort of nasty headlines ---这应该指的是"a new problem"
that inevitably lead to heads rolling in the executive suite:data insecurity.----这是定语从句，修饰the sort of nasty headlines

a new problem 主语
threatens谓语
to earn them 及后面的一大串宾语

正如老板和委员会终于解决了他们的最严重的账目和服从的麻烦，提高了他们的软弱，公司管理结构，一个新问题威胁到他们的收入，尤其是在美国-那种下流的标题，必然导致收入，在行政部门：资料不安全。
