    UnionBanCal Corporation (NYSE:UB) today reported second quarter
2006 net income of $182.9 million, or $1.26 per diluted common share,
compared with $1.27 per diluted common share a year earlier. Income
from continuing operations was $182.6 million, or $1.26 per diluted
common share, compared with $1.27 per diluted common share a year
earlier.
    First half 2006 net income was $355.9 million, or $2.44 per
diluted common share, compared with $2.49 per diluted common share for
first half 2005. Income from continuing operations was $364.1 million,
or $2.50 per diluted common share, compared with $2.47 per diluted
common share for first half 2005.
    "Second quarter results were solid and reflect our balanced
business model," stated Takashi Morimura, President and Chief
Executive Officer. "Strong loan growth and continued excellent credit
quality offset mixed deposit results, reflecting deposit pricing
pressures stemming from higher short-term interest rates and
heightened competition. During the quarter, we announced a 15 percent
increase in our common stock dividend and a $500 million extension of
our share repurchase program. These actions underscore our commitment
to enhancing shareholder value through effective capital management,
and reflect both the earnings power of the franchise and the strength
of our balance sheet."
    "Loan growth was robust across all categories in second quarter,"
added Chief Operating Officer Philip Flynn. "Commercial loans
increased 22 percent over prior year and almost 5 percent over first
quarter, while residential mortgages grew 14 percent over prior year
and 2.5 percent over first quarter. Credit quality continues to be
excellent. Second quarter net charge-offs were only $10 million and
nonperforming assets declined again, to just 0.07 percent of total
assets at quarter-end.
    "Average noninterest bearing deposits were flat in sequential
quarters, while interest bearing deposits increased 3.8 percent,"
continued Flynn. "The current interest rate environment has created
volume and pricing challenges for us and the entire industry. In
response, we are taking steps to defend our customer base and market
share. At the same time, our deposit franchise remains healthy and
profitable, driving one of the industry's lowest average all-in cost
of funds and a very solid net interest margin."

    Second Quarter Total Revenue From Continuing Operations

    For second quarter 2006, total revenue (taxable-equivalent net
interest income plus noninterest income) was $688 million, an increase
of $25 million, or 3.8 percent, compared with second quarter 2005. Net
interest income increased 2.0 percent, and noninterest income
increased 7.7 percent. Compared with first quarter 2006, total revenue
increased 0.6 percent, with net interest income and noninterest income
each increasing 0.6 percent.

    Second Quarter Net Interest Income (Taxable-equivalent) From
Continuing Operations

    Net interest income was $469 million in second quarter 2006, up $9
million, or 2.0 percent, from the same quarter a year ago, primarily
due to strong growth in loans.
    Average earning assets increased $1.7 billion, or 4.0 percent,
primarily due to a $4.5 billion, or 14.8 percent, increase in average
loans, while average securities declined $2.6 billion, or 23.7
percent. Average commercial loans increased $2.4 billion, or 22.4
percent, and average residential mortgages increased $1.4 billion, or
14.0 percent.
    Compared to second quarter 2005, average total deposits increased
$0.3 billion, or 0.8 percent. Average interest bearing deposits
increased $1.6 billion, or 7.6 percent. Average noninterest bearing
deposits decreased $1.3 billion, or 6.7 percent, primarily due to a
$733 million, or 22.5 percent, decrease in average title and escrow
deposits, and a $442 million, or 3.6 percent, decrease in average
other commercial noninterest bearing deposits. Average title and
escrow deposits decreased due to lower residential real estate
activity, and average other commercial noninterest bearing deposits
declined primarily due to changes in customer behavior in response to
rising short-term interest rates. Average consumer noninterest bearing
deposits decreased $90 million, or 2.7 percent.
    Average noninterest bearing deposits represented 44.2 percent of
average total deposits in second quarter 2006. The annualized average
all-in cost of funds was 1.76 percent, reflecting the Company's strong
average deposit-to-loan ratio of 113 percent and the high proportion
of noninterest bearing deposits to total deposits.
    The average yield on earning assets of $44.4 billion was 5.95
percent, up 80 basis points over second quarter 2005, with the average
loan yield increasing 51 basis points. The average rate on interest
bearing liabilities of $25.8 billion was 2.95 percent, up 142 basis
points compared with second quarter 2005, reflecting both higher
short-term interest rates and heightened competition for deposits.
Average interest bearing deposits were $22.1 billion and the weighted
average rate was 2.60 percent. Average core deposits funded 70.2
percent of average total assets in the second quarter. The net
interest margin in second quarter 2006 was 4.23 percent, compared with
4.32 percent in second quarter 2005.
    On a sequential quarter basis, net interest income increased $2.7
million, or 0.6 percent. Average loans increased $1.1 billion, or 3.2
percent. Average commercial loans increased $585 million, or 4.7
percent; average residential mortgages increased $289 million, or 2.5
percent; and average construction loans increased $201 million, or
13.2 percent. Average noninterest bearing deposits increased $26
million, or 0.1 percent, with consumer noninterest bearing deposits
decreasing $22 million and commercial noninterest bearing deposits
increasing $48 million, primarily due to a $138 million increase in
title and escrow deposits. The average yield on earning assets
increased 18 basis points and the average rate on interest bearing
liabilities increased 46 basis points. The net interest margin
decreased 13 basis points to 4.23 percent.

    Second Quarter Noninterest Income From Continuing Operations

    In second quarter 2006, noninterest income was $219 million, up
$16 million, or 7.7 percent, from the same quarter a year ago. Service
charges on deposit accounts increased $2 million, or 2.6 percent, and
trust and investment management fees increased $7 million, or 16.3
percent, primarily due to an increase in trust assets. Merchant
banking fees decreased $10 million, or 53.7 percent, primarily due to
an unusually high volume of syndications completed in second quarter
2005.
    Compared with the preceding quarter, second quarter 2006
noninterest income increased $1.3 million, or 0.6 percent. Service
charges on deposit accounts were flat, while trust and investment
management fees decreased 3.5 percent, primarily due to above-normal
trust fees in first quarter 2006, when the Company implemented a
refinement in accrual methodology.

    Second Quarter Noninterest Expense From Continuing Operations

    Noninterest expense for second quarter 2006 was $413 million, an
increase of $25 million, or 6.3 percent, over second quarter 2005.
Salaries and employee benefits expense increased $15 million, or 6.3
percent, primarily due to annual merit increases and higher
performance-related incentive expense. Higher incentive expense
included $5.4 million in stock option expense, versus none in 2005.
Professional services expense increased $3.9 million, or 29.6 percent,
primarily due to higher compliance-related expense. Foreclosed asset
expense (income) in second quarter 2006 reflected a $7.8 million gain
on the sale of property, compared with a $2.6 million gain in second
quarter 2005. The provision for off-balance sheet commitments was
negative $4 million in second quarter 2006, unchanged from the prior
year.
    Excluding the effect of stock option expense, noninterest expense
increased $19.2 million, or 4.9 percent, compared with prior year.
    Compared with first quarter 2006, noninterest expense decreased
$1.5 million, or 0.4 percent. Salaries and employee benefits expense
decreased $3.9 million, or 1.5 percent, primarily due to annual
seasonal factors that result in lower payroll taxes and 401(k)
matching contributions in the second quarter. The provision for
off-balance sheet commitments was negative $4 million, compared with
negative $3 million in first quarter 2006.

    Income Tax Expense From Continuing Operations

    The effective tax rate for second quarter 2006 was 33.5 percent,
compared with an effective tax rate of 34.8 percent for second quarter
2005, due to higher tax credits applied in the current year.

    Year-to-Date Results From Continuing Operations

    Total revenue was $1.4 billion in the first six months of 2006, an
increase of $67 million, or 5.1 percent, compared with total revenue
of $1.3 billion in the same period of 2005. Net interest income
increased 4.3 percent, and noninterest income increased 6.8 percent.
    Net interest income was $935 million in the first half of 2006, a
$39 million, or 4.3 percent, increase from prior year, primarily due
to growth in earning assets. Average loans increased $4.4 billion, or
14.7 percent, compared with the first six months of 2005. Compared
with prior year, the net interest margin increased 2 basis points, to
4.29 percent.
    Noninterest income in the first half of 2006 was $437 million, an
increase of $28 million, or 6.8 percent, over the same period in 2005.
Service charges on deposit accounts increased $4 million, or 2.8
percent. Trust and investment management fees increased $15 million,
or 17.9 percent, primarily due to growth in trust assets and a
refinement in accrual methodology implemented in first quarter 2006.
Insurance commissions decreased $4 million, or 9.9 percent, primarily
due to lower contingent commissions.
    For the first half of 2006, noninterest expense increased $46
million, or 5.9 percent, over the first half of 2005. Salaries and
employee benefits expense increased $35 million, or 7.6 percent,
primarily due to higher performance-related incentive expense
(including stock option expense of $11.6 million), merit increases,
and higher contract labor expense, reflecting compliance-related
initiatives. Outside services expense increased $12 million, or 24.3
percent, primarily due to higher cost of services related to title and
escrow balances, stemming from a higher earnings credit rate in the
first half of 2006, as well as higher trust administration expenses.
Professional services expense increased $7 million, or 26.9 percent,
primarily due to higher compliance-related expense. The provision for
off-balance sheet commitments was negative $7 million, compared with
negative $1 million in first half 2005.

    Credit Quality

    Nonperforming assets at June 30, 2006, were $36 million, or 0.07
percent of total assets. This compares with $42 million, or 0.09
percent of total assets, at March 31, 2006, and $69 million, or 0.13
percent of total assets, at June 30, 2005. Nonperforming assets
declined 48 percent between June 30, 2005 and June 30, 2006.
    In second quarter 2006, the total provision for credit losses was
negative $5.0 million. The total provision for credit losses was
negative $10.0 million in first quarter 2006 and negative $17.6
million in second quarter 2005. The total provision for credit losses
in second quarter 2006 consisted of a provision for loan losses of
negative $1 million and a provision for off-balance sheet commitments
(classified in noninterest expense) of negative $4 million. In second
quarter 2006, net charge-offs were $10 million, compared with net
charge-offs of $5 million in first quarter 2006, and net recoveries of
$7 million in second quarter 2005.
    At June 30, 2006, the allowance for credit losses as a percent of
total loans and as a percent of nonaccrual loans was 1.17 percent and
1130 percent, respectively. These ratios were 1.26 percent and 1003
percent, respectively, at March 31, 2006, and 1.54 percent and 721
percent, respectively, at June 30, 2005.

    Balance Sheet and Capital Ratios

    At June 30, 2006, the Company had total assets of $50.8 billion.
Total loans were $34.7 billion and total deposits were $40.5 billion,
resulting in a period-end deposit-to-loan ratio of 117 percent. Core

percent of total assets. At period-end, total stockholders' equity was
$4.6 billion, the tangible equity ratio was 8.19 percent, and the

respectively.

shares of common stock at a total price of $120.8 million, or an
average of $68.79 per repurchased share. For the first six months of

    Discontinued Operations

    On September 22, 2005, the Company announced the signing of a
definitive agreement to sell its international correspondent banking
business to Wachovia Bank, N.A. Commencing in third quarter 2005, all
results of the international correspondent banking business have been
reported as a discontinued operation and all prior periods have been
restated to reflect this accounting treatment. All of the assets and
liabilities of the discontinued operations have been separately
identified on the consolidated balance sheets (see Exhibit 4) and the
average net assets or liabilities of the discontinued operations are
reflected in the analysis of net interest margin (see Exhibits 6, 7
and 8).
    In the second quarter of 2006, the Company recorded net income
from discontinued operations of $0.3 million, which included a $4
million contingent purchase price payment. In the first quarter of
2006, the Company recorded a net loss from discontinued operations of
$8.5 million, or $0.06 per fully diluted common share.

    Third Quarter and Full Year 2006 Earnings Per Share Forecast

    The Company currently estimates that third quarter 2006 fully
diluted earnings per share from continuing operations will be in the
range of $1.21 to $1.26, including estimated stock option expense of
$0.02 per share and a total provision for credit losses of $5 million.
The Company currently estimates a loss from discontinued operations of
$0.01 per fully diluted share in the third quarter of 2006. Therefore,
net income per diluted common share is expected to be in the range of
$1.20 to $1.25.
    For full year 2006, the Company currently estimates that fully
diluted earnings per share from continuing operations will be in the
range of $4.90 to $5.05, including estimated stock option expense of
$0.09 per share and an estimated total provision for credit losses of
negative $5 million. In addition, the Company expects to record a net
loss from discontinued operations of approximately $0.07 per diluted
common share. Therefore, net income per diluted common share is
expected to be in the range of $4.83 to $4.98.

    Non-GAAP Financial Measures

financial measures reported under GAAP in that they exclude unusual or
non-recurring charges, losses, credits or gains. This press release
identifies the specific items excluded from the comparable GAAP

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.
