Rust Consulting is expected to mail the final wave of Independent Foreclosure Review checks in mid-July 2013, according to a statement updated Thursday by the Office of the Comptroller of the Currency. Previous statements had said that the final batch of compensation checks for eligible borrowers would be sent “during the summer.”

Staff members from the office of Rep. Elijah Cummings, D-Maryland, one of several Democrats who are closely following the mishaps of the Independent Foreclosure Review (IFR), are scheduled to meet with executives of Rust Consulting this week. Cummings and regulators are trying to figure out what exactly is going on with the firm, which has two decades of experience in managing financial settlements and claims.

Bank regulators keeping tally of checks cashed in the Independent Foreclosure Review (IFR) mailings put the running total at more than $2 billion as of Thursday, but that amount should have been higher if not for more fumbling by the paying agent, Rust Consulting. Now comes the sequel: delayed payments from the other agreement, the National Mortgage Settlement.

Former subsidiaries of Goldman Sachs (Litton Loan Servicing) and Morgan Stanley (Saxon Mortgage Services) are the 12th and 13th mortgage servicers to start compensating a total of nearly 4 million borrowers who went through foreclosures in 2009 and 2010 that were deemed to be wrongful or botched by bank regulators.
