Regulators are preparing to hand down their findings on the largestU.S. banks' resolution plans as early as this week, The Wall Street Journal reported April 12, citing "people familiarwith the matter."

The Federal Reserve and the FDIC have significant concerns aboutthe plans, commonly called "living wills," of JPMorgan Chase & Co., Bank of New York Mellon Corp. and State Street Corp., the report said, noting that the decisionsare not final and could change. It added that Bankof America Corp. may also receive an unfavorable verdict.

Citigroup Inc.is expected to receive a positive decision, the Journal stated, citing the anonymous sources. The report did not haveindications about the plans of GoldmanSachs Group Inc., MorganStanley or Wells Fargo& Co.

The Fed and the FDIC are also expected to detail specific issueswith the plans, as opposed to the blanket reasoning in public statements regardingthe rejection of all banks'living wills in 2014, the report added.
