ITEM 8.01  OTHER EVENTS.

As previously disclosed, Union Bank of California, N.A. (the "Bank"), the
Registrant's wholly-owned subsidiary, has been in discussions with the Office of
the Comptroller of the Currency ("OCC") and the Financial Crimes Enforcement
Network ("FinCEN") regarding the imposition of a cease and desist and civil
money penalty order by the OCC and a civil money penalty order by FinCEN
relating to the Bank's Bank Secrecy Act and anti-money laundering controls and
processes. Additionally, the Bank has been cooperating in an investigation by
the U.S. Department of Justice ("DOJ") pertaining to certain past activities
involving the Bank's now-discontinued international banking business. The Bank
sold its international banking business in October 2005.

The Registrant announced today in a press release filed herewith as Exhibit 99.1
that the Bank has entered into a settlement with the OCC, FinCEN and the DOJ.
The settlement involved the following actions:

     1.   On September 14, 2007, the Bank entered into a Stipulation and Consent
          to the Issuance of a Consent Order with the OCC and a Consent Order to
          a Civil Money Penalty and to Cease and Desist (the "Order"), copies of
          which are filed herewith as Exhibits 99.2 and 99.3, respectively. The
          Order supersedes the Memorandum of Understanding made by the Bank with
          the OCC on March 23, 2005. The Order imposes a civil money penalty of
          $10 million and requires the Bank to take actions to improve Bank
          Secrecy Act compliance. As previously disclosed in the Registrant's
          Quarterly Report on Form 10-Q for the quarter ended June 30, 2007
          under "Regulatory Matters," the amount of this penalty was charged in
          the second quarter of 2007.

     2.   On the same day, FinCEN executed an Assessment of Civil Money Penalty
          (the "Assessment") in the amount of $10 million, a copy of which is
          filed herewith as Exhibit 99.4. The Assessment provides that the $10
          million penalty is deemed to be satisfied by the Bank's payment of the
          civil money penalty of $10 million to the OCC.

     3.   On September 17, 2007, the Bank entered into a Deferred Prosecution
          Agreement ("DPA") with the DOJ, a copy of which is filed herewith as
          Exhibit 99.5. Under the DPA, the DOJ has agreed to defer prosecution
          for past violations relating to Bank Secrecy Act and anti-money
          laundering matters in the Bank's now discontinued international
          banking business and to dismiss prosecution completely if the Bank
          meets the conditions of the Order for one year. In the DPA, the Bank
          also agreed to a make a payment of $21.6 million to the DOJ.

The DOJ payment will be recorded in the quarter ending September 30, 2007, and
will be treated as a cost of discontinued operations. Management does not expect
its compliance with the Order, the Assessment or the DPA will have a material
impact on the Registrant's financial condition or liquidity, nor on the
Registrant's results of operations for periods subsequent to the current
quarter. Management is committed to making all improvements necessary to
strengthen the Bank's Bank Secrecy Act compliance program.

The foregoing descriptions of the Order, the Assessment and the DPA are
qualified in their entirety by reference to the complete text of the Order, the
Assessment and the DPA which are filed as exhibits to this Current Report on
Form 8-K and incorporated herein by reference.
