Freddie Simplifies Creation of Giant PCs. Late this week, Freddie Mac announced that it is adding new features to Dealer Direct, its online securitization portal, which will make it easier and faster for dealers to create customized Giant participation certificates. The new Dealer Direct Giant bulk upload feature allows dealers to upload proposed collateral for multiple Giants in a single collateral submission. A unique identifier is used to designate collateral for each Giant. Dealers also now have the option to upload a list of fixed-rate and/or adjustable-rate mortgage collateral without designating securities to specific Giants. Dealer Direct will analyze the individual securities and sort them into the largest possible Giant-eligible groups.
