Walter Investment Management Corp., a mortgage servicer, is seeking $1.63 billion in loans to refinance debt, according to a regulatory filing.

The company is offering a $1.5 billion seven-year, covenant-light loan at 3.75 percentage points more than the London interbank offered rate, according to a person with knowledge of the deal, who asked not to be identified because the terms aren’t set. The debt, which is being arranged by Credit Suisse Group AG, will have a 1 percent minimum on the lending benchmark. The company is also seeking a $125 million revolving-credit line.
