Freddie Mac last week cut some slack in the form of a lifeline to MGIC Investment Corp. which will allow the mortgage insurer to write additional policies even as the MI and the GSE work through a simmering dispute over pool insurance. On Sept. 28, MGIC announced that Freddie has reduced the amount of capital contribution MGIC Investment must pay its principal subsidiary MGIC to $100 million from $200 million. The GSE also extended the deadline for this contribution from Sept. 30 to Dec. 1.
