Pre-reform prevalence of final-sale accounting for repos

Ascertain the prevalence of final-sale accounting treatment for repo transactions prior to the post-2008 FASB reforms, quantifying how frequently institutions classified first-leg repos as sales rather than secured borrowings across the U.S. repo market before ASU 2011-03 and ASU 2014-11.

Background

Before the 2008 crisis, certain repo structures could be treated as first-leg final sales with the second-leg recognized as a forward contract, enabling removal of securities from balance sheets temporarily. High-profile cases such as Lehman’s Repo 105 and MF Global’s repo-to-maturity highlighted abuses and motivated FASB reforms that largely eliminated final-sale accounting for repos.

The paper indicates that despite these case studies, comprehensive evidence on how widespread final-sale accounting was across institutions and transactions prior to the reforms is lacking, making the historical prevalence an unresolved empirical question.

It is unclear how prevalent was the use of final-sale accounting prior to the reforms.
