Exhibit 99.1

    The Commerce Group, Inc. Announces 2005 Fourth Quarter Results
                        and Comparison to 2004

    WEBSTER, Mass.--(BUSINESS WIRE)--Feb. 2, 2006--The Commerce Group,
Inc. (NYSE:CGI) today reported 2005 fourth quarter results. Net
earnings were $63.5 million, or $1.87 per diluted share, compared to
net earnings of $71.7 million or $2.14 per diluted share for 2004.
    During the fourth quarter of 2005, the Company had net realized
investment gains of $2.1 million or $0.04 per diluted share, compared
to gains of $14.0 million or $0.27 per diluted share in the fourth
quarter of 2004. A complete breakdown of this information is included
in the attached tables.
    Earned premiums were $430.6 million for the fourth quarter of
2005, compared to $425.0 million for 2004. A schedule of direct
written premiums to earned premiums is included in the attached
tables.
    The fourth quarter GAAP consolidated operating combined ratio was
89.0%, compared to 87.5% for 2004. The increase in the combined ratio
was the result of an increase in the loss ratio partially offset by a
decrease in the underwriting ratio. The Company's GAAP consolidated
loss ratio for the fourth quarter of 2005 increased to 60.4% from
58.4% during the same period last year. The loss ratio increase was
the result of several factors, including an increase in loss
adjustment expenses and a small decline in the amount of favorable
loss reserve development compared to the fourth quarter of last year,
both partially offset by improved results from Commonwealth Automobile
Reinsurers and a decrease in personal automobile bodily injury claim
frequency. The Company's GAAP consolidated underwriting ratio
decreased to 28.6%, as compared to 29.1% for last year's fourth
quarter, primarily as a result of a decrease in our assessment from
the Massachusetts Insurance Insolvency Fund partially offset by
slightly higher accrued agents' profit sharing and higher 2005 policy
year mandated Massachusetts personal automobile commission rates.

    Cumulative December 31, 2005 Results

    Net earnings for 2005 were $243.9 million, or $7.21 per diluted
share, compared to net earnings of $214.4 million or $6.51 per diluted
share for 2004.
    During 2005, the Company had net realized investment gains of
$22.9 million or $0.44 per diluted share, compared to gains of $23.6
million or $0.47 per diluted share in 2004. A complete breakdown of
this information is included in the attached tables.
    Earned premiums were $1,709.9 million for 2005, compared to
$1,638.8 million for 2004. A schedule of direct written premiums to
earned premiums is included in the attached tables.
    The 2005 GAAP consolidated operating combined ratio was 88.7%,
compared to 90.0% for 2004. The decrease in the combined ratio was the
result of a decrease in the loss ratio partially offset by an increase
in the underwriting ratio. The Company's GAAP consolidated loss ratio
for 2005 decreased to 61.4% from 63.8% last year. The improvement was
the result of several factors, including: (1) an increase in average
earned premium revenue per automobile; (2) improved results from
C.A.R; and, (3) a decrease in the current year personal and commercial
automobile bodily injury claim frequency. These items were partially
offset by reduced favorable voluntary loss reserve development
compared to 2004. The Company's GAAP consolidated underwriting ratio
increased to 27.3%, as compared to 26.2% last year, primarily as a
result of significantly higher accrued agents' profit sharing and
slightly higher 2005 policy year mandated Massachusetts personal
automobile commission rates, both partially offset by a decrease in
our assessment from the Massachusetts Insurance Insolvency Fund. The
higher accrued agents' profit sharing is an outcome of the improved
loss ratio for 2005 versus 2004.
    A complete presentation of December 31, 2005 and 2004 financial
statement information is included in the financial statements attached
to this press release. All quarterly figures are unaudited and all
results are reported in accordance with accounting principles
generally accepted in the United States (GAAP). Additional
supplemental financial information will be available by Friday morning
on the Company's website at www.commerceinsurance.com, under the
"Links" section of the "News and Investor Information" area.
    At December 31, 2005, the Company had authority to purchase
approximately 858,000 additional shares of common stock under the
current Board of Directors' stock re-purchase authorization. During
2005, the Company issued approximately 187,000 shares of common stock
related to all option exercises. Approximately 133,000 of these issued
shares were from the American Commerce Insurance Company agents' stock
option program, of which approximately 2.4 million options remain
outstanding at various exercise prices and vesting dates. The
remainder of the issued shares resulted from the stock option program
for officers, of which approximately 11,000 options remain fully
vested and outstanding.

(1) GAAP consolidated operating ratios are calculated as in (2) below
    using the combined insurance subsidiaries' loss and underwriting
    results, adding to them the expenses of the holding companies
    (corporate expenses) in order to equal the loss and underwriting
    expense amounts on the income statement. For purposes of the U/W
    ratio, underwriting expenses are grossed-up for the increase
    (decrease) in deferred acquisition costs of ($10,780) and
    ($11,911) for the three months ended and $10,770 and $10,037 for
    the years ended December 31, 2005 and 2004, respectively.

(2) GAAP operating ratios for combined insurance subsidiaries are
    calculated as follows: (a) The loss ratio represents losses and
    LAE divided by earned premiums; and, (b) The underwriting ratio
    represents underwriting expenses (excluding changes in deferred
    acquisition costs), divided by net premiums written. No corporate
    expenses are included in the calculations.
