    Investment securities, including interest bearing deposits in other
financial institutions, have increased $99 million from September 30, 2003,
and are $40 million more than at December 31, 2003.  Additional investments
were made to utilize excess funding liquidity, and to capture the value of the
spread between short term funding rates and the rates on two-to-five year
maturity assets.

    Non-interest bearing deposits have increased $70 million, or 19 percent,
since December 31, 2003 and are $46 million, or 12 percent, greater than the
September 30, 2003 balance.  This continues to be a primary focus of our banks
and the programs we have initiated this past year continue to gain momentum.
Total deposits have increased $70 million from the September 30, 2003 balances
and $90 million from December 31, 2003.  This growth in deposits, a low cost
stable funding source, gives us increased flexibility in managing our asset
mix.  Federal Home Loan Bank advances have also increased, $77 million from
December 31, 2003, and $139 million from September 30, 2003, as we continue to
take advantage of the flexibility of that funding source in this current
period of low interest rates.  Repurchase agreements and other borrowed funds
also have increased from the prior year and from year end 2003 as we continue
to use these cost effective sources of funding.  On March 24, 2004,
subordinated debentures in the form of trust preferred securities of $45
million, with an interest rate of 5.79 percent, were issued.  The proceeds
were used for general corporate purposes.

    Total equity and book value per share amounts have increased substantially
from the prior year, primarily the result of earnings retention, and stock
options exercised. Net unrealized gains on securities available for sale of
$8 million at September 30, 2004 is greater than the $7 million at year end
2003 and the $4 million at September 30, 2003, and is primarily a function of
interest rate changes.

    Net Interest Income
    Net interest income for the quarter increased $3.721 million, or 16
percent, over the same period in 2003.  Total interest income increased $4.537
million, or 14 percent, while total interest expense was $816 thousand higher.
"Premium amortization on our investments was reduced significantly from the
second quarter due to a substantial reduction in the level of mortgage
prepayments which resulted in higher returns on our investments," said
Blodnick.  The investment portfolio generated approximately 64 percent of the
increase in interest income with the remainder coming from the increase in
loans outstanding.  The increase in interest expense is primarily attributed
to the increase in non-interest bearing deposits and a reduction in rates on
maturing fixed term interest bearing deposits.  The net interest margin as a
percentage of earning assets, on a tax equivalent basis, was 4.11 percent
which was near the 4.12 percent result for the third quarter of 2003.  The
margin for the third quarter increased from the 4.04 percent experienced for
the second quarter of 2004.  Premium amortization on mortgage related
investments for the third quarter was $2.722 million, a decrease of $745
thousand from the second quarter and a decrease of $1.254 million from the
third quarter of last year.  "We continue to deploy a strategy of investing in
short term securities that carry lower current yields. We believe it is
inappropriate in this rate environment to extend maturities in order to
achieve higher yields," said Blodnick.

    Non-interest Income
    Fee income increased $1.265 million, or 24 percent, over the same period
last year, driven primarily by an increased number of loan and deposit
accounts and additional customer services offered.  Gain on sale of loans
decreased $1.047 million from the third quarter of last year, because of
greatly reduced refinance activity, but increased $185 thousand from this
years' second quarter which was $255 thousand higher than the first quarter.
Loan origination activity for housing purchases remains quite strong in our
markets, with $176 million in residential loans originated in the third
quarter and $488 million year to date.

    Non-interest Expense
    Non-interest expense increased by $942 thousand, or 6 percent, from the
same quarter of 2003 including expenses from the Ione branch acquisition, two
additional branches in Boise, Idaho, and a new branch in downtown Bozeman,
Montana.  Compensation and benefit expense increased $619 thousand, or 7
percent from the third quarter of 2003, with the additional bank branches,
normal compensation increases for job performance and increased cost for
benefits tied to Company performance, accounting for the majority of the
increase.  Occupancy and equipment expense increased $126 thousand, or 5
percent, reflecting the cost of the additional locations.  Outsourced data
processing expense decreased by $47 thousand.  Other expenses increased $287
thousand, or 7 percent, primarily from additional marketing expenses, and
costs associated with new branch offices.  The efficiency ratio (non-interest
expense/net interest income + non-interest income) was 49 percent for the 2004
quarter which is a significant improvement from the 52 percent for the 2003
quarter.

    Net Interest Income
    Net interest income for the first nine months increased $12.088 million,
or 18 percent, over the same period in 2003.  Total interest income was
$11.768 million, or 12 percent higher than the same period in 2003, while
total interest expense was $320 thousand lower.  The investment portfolio
generated approximately 76 percent of the increase in interest income.
Additional interest income from the large increase in loans outstanding was
partially offset by lower rates on the loan portfolio due to refinancing, and
re-pricing of existing loans.  The decrease in interest expense is primarily
attributed to the increase in non-interest bearing deposits and a reduction in
rates on maturing fixed term interest bearing deposits and Federal Home Loan
Bank borrowings.  The interest expense on the subordinated debentures issued
in March 2004 partially offset the above described reductions.  The net
interest margin as a percentage of earning assets, on a tax equivalent basis,
was 4.15 percent which was a decrease from 4.21 percent for the same period in
2003.

    Non-interest Income
    Fee income increased $3.082 million, or 21 percent, over the same period
last year, driven primarily by an increased number of loan and deposit
accounts and the fee income associated with this growth in accounts.  Gain on
sale of loans decreased $2.732 million, or 31 percent, from last year, because
of greatly reduced refinance activity.  Loan origination activity for housing
purchases remains quite strong in our markets.  In 2003 gains on sale of
investments, net of impairment charge, of $1.253 million were recorded and
zero gains were realized in 2004.

    Non-interest Expense
    Non-interest expense increased by $5.168 million, or 11 percent, from 2003
including expenses from the acquisitions, two additional branches in Boise,
Idaho, and a new branch in downtown Bozeman, one of the fastest growing cities
in Montana.  Compensation and benefit expense increased $3.247 million, or 12
percent, with the additional bank branches, normal compensation increases for
job performance and increased cost for benefits tied to Company performance,
accounting for the majority of the increase.  Occupancy and equipment expense
increased $760 thousand, or 10 percent, reflecting the cost of the additional
locations.  Outsourced data processing expense decreased by $94 thousand, the
result of bringing all core processing onto our in-house data systems, offset
somewhat by increased item capture expenses for Mountain West Bank resulting
from increased volumes.  Other expenses increased $1.382 million, or 11
percent, primarily from start up expenses on implementing the High Performance
Checking program at the four banks not previously on the program, additional
advertising expense, and costs associated with new branch offices and the
acquisitions.  The efficiency ratio (non-interest expense/net interest income
+ non-interest income) was 51 percent, improving slightly from the 52 percent
in 2003, excluding the gain on sale of securities.

    Allowance for Loan Loss and Non-Performing Assets
    The provision expense for loan losses was $2.995 million, which is a
decrease of $118 thousand from the prior year's provision.  Net charge offs as
a percentage of loans outstanding were .054 percent year-to-date, or .072
percent annualized, for 2004 which is down from .118 percent for the full year
in 2003.

    Cash dividend
    On September 29, 2004, the board of directors declared a cash dividend of
$.17 payable October 21, 2004 to shareholders of record on October 12, 2004.
This was a $.01 increase from the same quarter's dividend in 2003, a 6 percent
increase, and is a $.07 increase in dividends declared for the year, a 16
percent increase.
