Employees at the Royal Bank of Scotland (RBS) joked about crippling the U.S. housing market before the 2008 financial crisis, according to transcripts released by the Department of Justice (DOJ) last week.

According to DOJ transcripts, senior staff described loans they were trading as “total f–king garbage.” DOJ also found that the Sottish bank’s chief credit officer in the U.S. said the loans were “all disguised to, you know, look okay kind of … in a data file.”

The release of the email and call transcripts were part of a DOJ report, which resulted from a $4.9 billion settlement with RBS, Business Insider reported.

In its report, DOJ accused RBS of making “false and misleading representations” to sell more residential mortgage-backed securities to investors. The Justice Department added that executives “showed little regard for their misconduct and, internally, made light of it.”
