Congressional Budget Office Cost Estimate: H.R. 4294: Prevention of Private Information Dissemination Act of 2017 [open pdf - 87KB]
"Large bank holding companies and certain nonbank financial companies are currently subject to extra supervision, capital requirements, and stress testing under the Dodd- Frank Wall Street Reform and Consumer Protection Act. In connection with that enhanced supervision, H.R. 4294 would establish a criminal penalty for federal employees who willfully disclose individually identifiable information collected from those institutions and for those who obtain such information under false pretenses. Both penalties would be set at $5,000. Because people who are prosecuted and convicted under H.R. 4294 could be subject to criminal fines, the federal government would probably collect additional penalties under the bill. Such fines are recorded as revenues, deposited in the Crime Victims Fund, and later spent without further appropriation action."
