    UnionBanCal Corporation Reports 16% Increase in Third Quarter
Net Income Per Share and 19% Increase in Operating Earnings Per Share


    SAN FRANCISCO--(BUSINESS WIRE)--Oct. 15, 2003--UnionBanCal
Corporation (NYSE:UB) today reported third quarter 2003 net income of
$155.0 million, or $1.02 per diluted common share, a 15.9 percent
increase over the $0.88 per diluted common share earned in third
quarter 2002. Operating earnings were the same as net income for the
quarter, representing an 18.6 percent increase over operating earnings
of $0.86 per diluted common share in third quarter 2002. Operating
earnings for third quarter 2002 excluded the after-tax effect of a
$3.2 million net reduction in income tax expense attributable to a
permanent reduction in taxes associated with changes in California
state tax law.
    For the first nine months of 2003, net income was $435.3 million,
up $52.4 million, or 13.7 percent, compared with the same period last
year. Net income per diluted common share was $2.87, up 18.1 percent
over the first nine months of 2002, while operating earnings per
diluted common share were $2.83, up 17.9 percent.
    "I am pleased with both our third quarter and year-to-date
results," stated Norimichi Kanari, President and Chief Executive
Officer. "Our 18.6 percent increase in third quarter operating
earnings per share was fueled by excellent deposit growth, which led
to higher net interest income and noninterest income. Total revenue
was more than 7 percent higher than prior year, despite a markedly
lower interest rate environment. Noninterest income grew 19 percent
over last year, and represented 33 percent of total revenue for the
quarter, up from 30 percent a year earlier, demonstrating the ongoing
success of our strategic initiatives emphasizing fee income growth. In
addition, asset quality continued to improve, resulting in a lower
provision for credit losses.
    "During the quarter, we completed the acquisition of Monterey Bay
Bank, which added eight full-service branches in the greater Monterey
Bay area to Union Bank of California's existing branch network, and we
announced our agreement to acquire Business Bank of California, which
operates 15 branches in southern and northern California. The Business
Bank acquisition is expected to close early next year and will further
advance our strategy of extending and adding density to our footprint
in California," continued Kanari.
    "In September, we announced the repurchase of 6.7 million shares
of common stock from our majority shareholder, The Bank of
Tokyo-Mitsubishi, for $300 million," continued Kanari. "The
transaction further demonstrates our commitment to prudently manage
capital and provide increased returns to our shareholders. Our recent
capital management initiatives have contributed significantly to the
200 basis point increase in our third quarter operating return on
equity," concluded Kanari.

    Total Revenue

    For third quarter 2003, total revenue (taxable-equivalent net
interest income plus noninterest income) was $603.2 million, an
increase of $ 41.5 million, or 7.4 percent, compared with third
quarter 2002. Net interest income increased 2.3 percent, while
noninterest income increased 19.1 percent. Compared with second
quarter 2003, total revenue on an operating basis was $22.6 million,
or 3.9 percent, higher with net interest income increasing 4.0 percent
and noninterest income on an operating basis increasing 3.8 percent.

    Net Interest Income (Taxable-equivalent)

    Net interest income was $401.7 million in third quarter 2003, up
$9.1 million from the same quarter a year ago. Volume gains in
deposits and earning assets were largely offset by the effects of the
lower interest rate environment and a shift in the mix of earning
assets. Average earning assets grew $5.1 billion, or 15.6 percent,
primarily due to a $4.0 billion, or 67.7 percent, increase in average
securities, a $763 million, or 164.6 percent, increase in average
money market assets, and a $361 million, or 1.4 percent, increase in
average loans. Average residential mortgages increased $1.4 billion,
or 24.5 percent, and average commercial mortgages increased $400
million, or 10.4 percent. Average commercial loans decreased $1.6
billion, or 14.1 percent, primarily due to weak commercial loan
demand. Average noninterest bearing deposits increased $3.8 billion,
or 30.6 percent, with title and escrow deposits increasing 56 percent
and other business demand deposits increasing 27 percent. Average
noninterest bearing deposits represented 46.8 percent of total
deposits, up from 43.9 percent in the same quarter a year ago. The
annualized all-in cost of funds contracted to just 0.50 percent.
    Due to the lower interest rate environment, the average yield on
earning assets of $37.9 billion declined 92 basis points
year-over-year, while the average rate on interest bearing liabilities
of $20.8 billion fell 63 basis points. The net interest margin in
third quarter 2003 was 4.22 percent, a decrease of 55 basis points
compared with third quarter 2002.
    On a sequential quarter basis, net interest income increased $15.3
million, or 4.0 percent. Average earning assets grew $1.8 billion, or
4.9 percent, with average securities increasing $2.2 billion, or 29.0
percent, and average loans declining $185 million, or 0.7 percent.
Average noninterest bearing deposits increased $1.3 billion, or 8.6
percent. The net interest margin decreased 7 basis points to 4.22
percent.

    Noninterest Income

    In third quarter 2003, noninterest income on an operating basis
was $201.5 million, up $32.4 million, or 19.1 percent, from the same
quarter a year ago. Service charges on deposit accounts increased
$13.2 million, or 19.2 percent, primarily due to higher deposit
volumes and higher account analysis and overdraft fees. Trust and
investment management fees were flat, and insurance commissions
increased $9.6 million, to $15.8 million, primarily reflecting the
fourth quarter 2002 acquisition of John Burnham Insurance Services and
the second quarter 2003 acquisition of Tanner Insurance Brokers.
    Noninterest income on an operating basis increased $7.3 million,
or 3.8 percent, on a sequential quarter basis. Service charges on
deposits increased $3.9 million, or 5.0 percent, and trust and
investment management fees increased $2.3 million, or 6.9 percent.

    Noninterest Expense

    Noninterest expense for third quarter 2003 was $348.9 million, an
increase of $31.0 million, or 9.8 percent, over third quarter 2002.
Salaries and other compensation expense increased $17.6 million, or
11.6 percent, primarily due to higher employee count associated with
acquisitions and de novo branch openings, and annual merit increases.
Employee benefits expense increased $5.4 million, or 17.8 percent,
primarily due to higher employee count associated with acquisitions
and de novo branch openings, and increases in health benefits expense
for both current employees and retirees. Intangible asset amortization
expense was $2.6 million, an increase of $1.1 million compared with
prior year, due to recent acquisitions.
    Compared with second quarter 2003, noninterest expense on an
operating basis increased $2.1 million, or 0.6 percent. Salaries and
other compensation expense increased $8.1 million, or 5.0 percent, due
primarily to higher performance-related incentive expense and higher
employee count associated with acquisitions.
    The operating efficiency ratio for third quarter 2003 was 57.8
percent, compared with 56.6 percent in third quarter 2002, and 59.7
percent in second quarter 2003. The increase in the efficiency ratio
versus prior year was due primarily to the lower interest rate
environment in third quarter 2003 and its adverse effect on net
interest income.

    Year-to-Date Results

    For the first nine months of 2003, total revenue on an operating
basis was $1.8 billion, an increase of $97 million, or 5.8 percent,
compared with the same period in 2002. Net interest income increased
1.7 percent, and noninterest income on an operating basis increased
15.3 percent.
    Net interest income was $1.2 billion in the first nine months of
2003, a $20 million, or 1.7 percent, increase from the same period a
year ago. The positive effect of higher volumes of noninterest bearing
demand deposits and earning assets was substantially offset by the
adverse effect of the lower interest rate environment in 2003.
Compared with prior year, net interest margin for the first nine
months declined 42 basis points, to 4.35 percent.
    Noninterest income on an operating basis in the first nine months
of 2003 increased $76.9 million, or 15.3 percent, over the same period
in 2002. Service charges on deposits increased $27.4 million, or 13.4
percent, primarily due to higher account analysis and overdraft fees,
and higher deposit volumes. Trust and investment management fees
decreased $8.4 million, or 7.7 percent, while insurance commissions
increased $25.1 million, or 125.6 percent, due primarily to recent
insurance brokerage acquisitions. In the first nine months of 2003,
auto lease residual writedowns were $0.3 million, compared with $9.0
million in the first nine months of 2002.
    For the first nine months of 2003, noninterest expense on an
operating basis increased $92.2 million, or 9.7 percent, over the same
period in 2002. Salaries and other compensation expense increased
$35.6 million, or 7.9 percent, primarily due to merit increases and
higher employee count associated with recent acquisitions and de novo
branch openings. Employee benefits expense increased $19.4 million, or
19.7 percent, primarily due to higher health benefits expense for
current employees and retirees, and to higher employee count.
Intangible asset amortization expense was $8.3 million, an increase of
$4.6 million compared with prior year, due to recent acquisitions. The
operating efficiency ratio for the first nine months of 2003 was 59.0
percent, compared with 56.8 percent in the first nine months of 2002.
The increase in the efficiency ratio was due primarily to the lower
interest rate environment in 2003 and its adverse effect on net
interest income.

    Credit Quality

    Nonperforming assets at September 30, 2003, were $344 million, or
0.81 percent of total assets. This compares with $380 million, or 0.89
percent of total assets at June 30, 2003, and $396 million, or 1.05
percent of total assets, at September 30, 2002.
    For third quarter 2003, the provision for credit losses was $20
million, compared with $25 million in second quarter 2003, and $40
million in third quarter 2002. Net loans charged off in third quarter
2003 were $38 million, compared with $53 million in second quarter
2003, and $42 million in third quarter 2002.
    At September 30, 2003, the allowance for credit losses as a
percent of total loans and as a percent of nonaccrual loans was 2.11
percent and 161.4 percent, respectively. These ratios were 2.17
percent and 147.1 percent, respectively, at June 30, 2003, and 2.40
percent and 157.7 percent, respectively, at September 30, 2002.

    Balance Sheet and Capital Ratios

    At September 30, 2003, the Company had total assets of $42.6
billion and total deposits of $36.0 billion. Total shareholders'
equity was $3.7 billion and the tangible equity ratio was 8.05
percent. Book value per share was $25.32, up 4.5 percent from a year
earlier. The Company's Tier I and total risk based capital ratios at
September 30, 2003, were 10.96 percent and 12.58 percent,
respectively.

repurchased 6.7 million shares of common stock, at a price of $45.05

shares during the quarter. At September 30, 2003, the Company had
authority from its Board of Directors to repurchase an additional $115
million of common stock under its common stock repurchase plan.
    Common shares outstanding at September 30, 2003, were 145.1
million, a decrease of 5.1 million shares, or 3.4 percent, from one
year earlier.

    Fourth Quarter 2003 Earnings Per Share Guidance

    Use of Non-GAAP Financial Measures

    This press release contains certain references to operating
earnings, and other financial measures identified as being stated on
"an operating basis" or qualified by the word "operating", that
include adjustments from comparable measures calculated and presented
in accordance with accounting principles generally accepted in the
United States of America (GAAP). Operating earnings, as used herein,
differs from net income reported under GAAP in that operating earnings
excludes unusual or non-recurring charges, losses, credits or gains.
Similarly, other financial measures that are identified herein as
being stated on "an operating basis" or qualified by the word
"operating" exclude these unusual or non-recurring charges, losses,
credits or gains. This press release identifies the specific items
excluded from the comparable GAAP financial measure in the calculation
of each non-GAAP financial measure. Because these items and their
impact on the Company's performance are difficult to predict,
management believes that financial presentations excluding the impact
of these items provide useful supplemental information which is
important to a proper understanding of the Company's core business
results by investors. These presentations should not be viewed as a
substitute for results determined in accordance with GAAP, nor are
they necessarily comparable to non-GAAP financial measures presented
by other companies. For a detailed reconciliation of data presented on
an operating basis to GAAP financial measures, please refer to
Exhibits 5 and 6 accompanying this press release.

(1) Yields and interest income are presented on a taxable-equivalent
    basis using the federal statutory tax rate of 35 percent.

(2) Average balances on loans outstanding include all nonperforming
    loans. The amortized portion of net loan origination fees (costs)
    is included in interest income on loans, representing an
    adjustment to the yield.

(3) Foreign loans and deposits are those loans and deposits originated
    in foreign branches.
