NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

September 30, 2005



Basis of Presentation



The condensed consolidated financial statements included herein have been prepared by AmerInst Insurance Group, Ltd. (AmerInst) without audit,
pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments, consisting of normal recurring accruals, which are, in the opinion of management, necessary for a fair presentation of the results of
operations for the periods shown. These statements are condensed and do not incorporate all the information required under generally accepted accounting principles to be included in a full set of financial statements. It is suggested that these
condensed statements be read in conjunction with the consolidated financial statements at and for the year ended December 31, 2004 and notes thereto, included in AmerInsts annual report on Form 10-K for the year ended December 31,
2004.



In June 2005, the FASB directed its staff to issue the
proposed FSP EITF Issue 03-1-a as final and it will be retitled FSP FAS 115-1, The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments. It replaces existing guidance and clarifies that an impairment
should be recognized as a loss at a date no later than when the impairment is deemed other-than-temporary, even if the decision to sell has not been made. FSP FAS 115-1 is effective for other-than-temporary impairment analysis conducted in periods
beginning after September 15, 2005. The Company believes that its current policy on other-than-temporary impairments complies with FSP FAS 115-1. Accordingly, the adoption of this standard has no impact on the Companys results of
operations or financial condition.



Tender Offer



On December 17, 2004, AmerInst Investment Company, Ltd. commenced a
modified Dutch auction self-tender offer for AmerInst shares. Pursuant to the tender offer, which expired on January 21, 2005, 65,959 shares were accepted for purchase at a price of $60.00 per share, for a total purchase price of
$4,298,229, including tender offer expenses of $340,698.

Part I, Item 2



MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



OVERVIEW



Unless otherwise indicated by the context, in this quarterly report we refer
to AmerInst Insurance Group, Ltd. and its subsidiaries as the Company, we or us. Also, unless otherwise indicated by the context, AmerInst means the parent company, AmerInst Insurance Group, Ltd.



Our primary purpose is to maintain an insurance company which
is intended to exert a stabilizing influence on the design, pricing and availability of accountants professional liability insurance. Historically, the sole business activity of our wholly owned insurance company subsidiary, AmerInst Insurance
Company, Ltd., has been to act as a reinsurer of professional liability insurance policies that are issued under the Professional Liability Insurance Plan sponsored by the American Institute of Certified Public Accountants (AICPA). The AICPA plan
offers professional liability coverage to accounting firms in all 50 states. Currently approximately 24,000 accounting firms are insured under this plan. In 2003, we reinsured insurance written for attorneys professional liability. This
participation terminated on December 31, 2003. We continue to look for ways in which it may be advantageous to expand our business to include the reinsurance of lines of coverage other than accountants professional liability. Any such
expansion may be subject to our obtaining regulatory approvals.



Our reinsurance activity depends upon agreements with outside parties. In August 1993 we began the current reinsurance relationship with CNA, taking a 10% participation of the first $1,000,000 of liability of each policy written under the
AICPA plan. Effective in December 1999, we began taking a 10% share of CNAs value plan business. The value plan provides for separate limits up to $1,000,000 for losses and separate limits up to $1,000,000 for expenses
per occurrence and $2,000,000 in the aggregate. Our maximum limits under the value plan are $2,000,000 per occurrence and $4,000,000 in the aggregate.



Third-party Managers and Service Providers



USA Risk Group (Bermuda) Ltd. provides the day-to-day services necessary for the administration of our business. Shareholder services are conducted by
USA Risk Group of Vermont, Inc., an affiliate of USA Risk Group (Bermuda) Ltd.



The Country Club Bank of Kansas City, Missouri, provides portfolio management of fixed-income securities and directs our investments pursuant to guidelines approved by us. Harris Associates, L.P., Harris Alternatives
Investment Group, and Northeast Investment Management, Inc. provide discretionary investment advice with respect to our equity investments.



Professional Liability Coverage



The form of professional liability policy issued by CNA which we ultimately reinsure is a Professional Liability Company Indemnity Policy form. The
coverage provided under this policy is on a claims made basis, which means the policy covers only those losses resulting from claims asserted against the insured during the policy period. The insuring clause of the policy, which
indemnifies for losses caused by acts, errors or omissions in the insureds performance of professional accounting services for others, is in three parts:



Clause A indemnifies the accounting firm insured and, unless excluded by endorsements, any predecessor firms;



Clause B indemnifies any accountant or accounting firm while performing
professional accounting services under contract with the insured;



Clause C indemnifies any former or new partner, officer, director or employee of the firm or predecessor firms.



Depending on the insured, defense costs for the policies issued by CNA (and reinsured by us) are either within the policy limits or in addition to policy
limits. CNA charges additional premiums to cover the cost of providing defense costs in addition to the policy limits under its value plan. Insureds under the value plan have separate limits for losses and defense costs. There are a few
states in which, if the insured contests the settlement recommended by the insurer, those policies will only cover costs that do not exceed the lesser of the amount for which the claim could have been settled or the policy limits.

OPERATIONS



Three months ended September 30, 2005 compared to three months ended September 30, 2004:



We recorded net income of $289,507 for the third quarter of 2005 compared to net income of $22,063 for the same period of
2004. This improvement was due to a decrease in our recorded losses and an improvement of our investment returns. Our earned premiums for the third quarter of 2005 were $2,226,448 compared to $2,302,646 for the third quarter of 2004, a decrease of
3.3%. The decrease in earned premiums was due to the timing of policies written under the current treaty compared to the same period in 2004. Net premiums written for the three months ended September 30, 2005 were $2,021,827, compared to
$2,472,805 for the third quarter of 2004, a decrease of $450,978 or 18.2%. The decrease in net premiums written was primarily attributable to a decrease in CNAs program writings for the third quarter due to a decrease in the number of policies
written and a slight decrease in policy rates.



Our loss ratio
for the third quarter of 2005 was 70.1%, compared to 79.9% for the same period of 2004. The loss ratio represents our managements current estimate of the effective loss rate selected in consultation with our independent consulting actuary. To
determine total losses for the third quarter of 2005, we multiplied an estimated loss ratio of 70% times the AICPA Professional Liability Insurance Plan net premiums. For the third quarter of 2004, to determine total losses we multiplied an
estimated loss ratio of 80% times the AICPA Professional Liability Insurance Plan current premiums earned and 75% times the attorneys professional liability plan net premiums earned. Our actual overall loss ratio for the year ended
December 31, 2004 was 57.6%. The 70% loss ratio applied to the AICPA Professional Liability Insurance Plan current premiums in 2005 is a decrease from the loss ratio of 80% for the comparable period of 2004 and is the result of favorable loss
trends.

AMERINST INSURANCE GROUP, LTD.



OPERATIONS(Continued)



We expensed policy acquisition costs of $632,262 in the third quarter of 2005 compared to $675,679 for the same period of 2004, a decrease of $43,417 or
6.4%. These costs were 28.4% and 29.2% of net premiums earned for the quarters ended September 30, 2005 and 2004, respectively. Policy acquisition costs are the sum of ceding commissions paid to ceding companies, determined contractually
pursuant to reinsurance agreements, and federal excise taxes paid on premiums written to ceding companies.



We expensed operating and management expenses of $312,929 in the third quarter of 2005 compared to $394,609 for the same period of 2004, a decrease of
$81,680 or 20.7%. The decrease is primarily attributable to costs for strategic and business planning legal fees incurred during the third quarter of 2004, not incurred for the same period of 2005.



We recorded net underwriting income (net premiums earned less the sum of loss
and loss adjustment expenses and policy acquisition costs) of $33,361 for the third quarter of 2005 compared to a net underwriting loss of $214,175 for the same period of 2004, an improvement of $247,536. The improvement was primarily due to an
increase in net premiums earned and a decrease in recorded losses resulting from using an estimated loss ratio of 70.1% (as a result of favorable loss development) for the third quarter of 2005 compared to an estimated loss ratio of 79.9% for the
comparable period in 2004.



We recorded net investment income
of $281,948 in the third quarter of 2005 compared to $378,898 for the same period of 2004, a decrease of $96,950 or 25.6%. The entire decrease was the result of lower interest income as higher interest rate securities matured and were replaced by
securities with a lower yield. Annualized investment yield, calculated as the net average amount of total investments divided by interest and dividend income, was 2.3% for the third quarter of 2005, a decrease from the 2.9% yield earned in the third
quarter of 2004. The decrease in investment yield was due to an overall lower interest rate environment for the fixed income portion of the portfolio. Sales of securities during the third quarter of 2005 resulted in realized capital gains of
$287,127, compared to gains of $251,949 in the third quarter of 2004. Gains recorded in the third quarter of 2005 primarily related to sales of equity securities. Proceeds of these sales were subsequently reinvested in other equity securities.



Nine months ended September 30, 2005 compared to nine months ended
September 30, 2004:



We recorded net income of
$892,835 for the nine months ended September 30, 2005 compared to a net loss of $227,737 for the nine months ended September 30, 2004. This improvement is due to an increase in net premiums earned and net realized gain on investments and a
decrease in recorded losses and loss adjustment expenses, offset by a decrease in net investment income, an increase in our policy acquisition costs and operating and management expenses.



Our net premiums earned for the first nine months of 2005 were $6,693,296 compared to $6,559,066 for 2004. The change of
$134,230 represented a 2.0% increase. Premiums written in the nine months ended September 30, 2005 were $6,444,651 compared to $6,258,444 for the same period in 2004.



Our loss ratio for the first nine months of 2005 was 70.4% compared to 79.9% for the same period of 2004. The loss ratio
represents our managements current estimate of the effective loss rate selected in consultation with our independent consulting actuary. To determine total losses for the first nine months of 2005, we multiplied an estimated loss ratio of 70%
times the AICPA Professional Liability Insurance Plan net premiums earned and have recorded additional reserves relating to the attorneys professional liability plan. For the first nine months of 2004, to determine total losses we multiplied
an estimated loss ratio of 80% times the AICPA Professional Liability Insurance Plan current premiums earned and 75% times the attorneys professional liability plan net premiums earned. Our actual overall loss ratio for the year ended
December 31, 2004 was 57.6%. The 70% loss ratio applied to the AICPA Professional Liability Insurance Plan current premiums in 2005 is a decrease from the loss ratio of 80% for the comparable period of 2004 due to favorable loss trends.



We expensed policy acquisition costs of $1,950,673 in the
first nine months of 2005 compared to $1,915,154 for the same period of 2004, an increase of $35,519 or 1.9%. These costs were 29.1% and 29.2% of premiums earned for the nine-month periods ended September 30, 2005 and 2004, respectively. The
increase in policy acquisition costs in 2005 was due to the increase in net premiums earned. Policy acquisition costs are the sum of ceding commissions paid to ceding companies, which are determined contractually pursuant to reinsurance agreements,
and federal excise taxes paid on premiums written to ceding companies.

We recorded net underwriting income (net premiums earned less the sum of loss and loss adjustment
expenses and policy acquisition costs) of $30,168 for the nine month period ended September 30, 2005 compared to a net underwriting loss of $598,165 for the same period in 2004, an improvement of $628,333. The more favorable underwriting
results in 2005 were primarily due to an increase in net premiums earned and a decrease in net incurred losses.



We realized capital gains of $1,249,351 during the nine months ended September 30, 2005 compared to $439,000 in capital gains in the same period of
2004. Gains recorded in 2005 primarily related to sales of equity securities. Proceeds of these sales were reinvested in other equity securities. Net investment income through September 30, 2005 was $820,000 compared to $972,095 for the same
period of 2004. Investment yield for the nine months ended September 30, 2005 was approximately 3.2% as compared to 2.4% for the first nine months of 2004.

AMERINST INSURANCE GROUP, LTD.



FINANCIAL CONDITION AND LIQUIDITY



As of September 30, 2005, our total investments were $46,311,893, a decrease of $5,480,324, or 10.6%, from $51,792,217 at December 31, 2004. The
decrease was primarily due to the sale of fixed income securities to fund the purchase of shares pursuant to the self-tender offer described below. Cash and cash equivalents balances increased from $1,523,928 at December 31, 2004 to $2,397,395
at September 30, 2005, an increase of $873,467, or 57.3%. The amount of cash and cash equivalents varies depending on the maturities of fixed term investments and on the level of funds invested in money market mutual funds. The ratio of cash
and total investments to total liabilities at September 30, 2005 was 1.37:1, compared to a ratio of 1.58:1 at December 31, 2004.



Assumed reinsurance balances receivable are current assumed premiums receivable less commissions payable to the issuing carriers less assumed losses
payable. This balance was a receivable of $877,846 at December 31, 2004 and was $1,753,880 at September 30, 2005. A $1,152,115 payable has been recorded as assumed reinsurance balances payable relating to CNA accountants professional
liability plan. These balances fluctuate due to the timing of renewal premiums written and assumed losses paid.



The Bermuda Monetary Authority previously authorized the purchase of up to 15,000 of our shares by AmerInst Investment Company, Ltd. Such purchases are
made through privately negotiated transactions and are in addition to our practice of purchasing the shares of individuals who have died or retired from the practice of public accounting. Subsequently, the Authority authorized blanket permission for
AmerInst Investment Company, Ltd. to purchase common shares without limit from individuals who have died or retired from the practice of public accounting and on a negotiated case-by-case basis. Through November 2, 2005, AmerInst Investment
Company, Ltd. had purchased in negotiated transactions at various prices 18,433 common shares for a total purchase price of $609,503. In addition, through that date, AmerInst Investment Company, Ltd. had purchased 21,203 common shares from
individuals who had died or retired for a total purchase price of $1,096,241. In connection with the tender offer described below, the Authority separately authorized the acquisition by AmerInst Investment Company, Ltd. of up to 20% of our
outstanding shares.



On December 17, 2004, AmerInst
Investment Company, Ltd. commenced a modified Dutch auction self-tender offer for AmerInst shares. Pursuant to the tender offer, which expired on January 21, 2005, 65,959 shares were accepted for purchase at a price of $60.00 per
share, for a total purchase price of $4,298,229, including tender offer expenses of $340,698.



We paid our first semi-annual dividend of $1.30 per share during the third quarter of 2005. The next semi-annual dividend of $1.30 per share will occur during the first quarter of 2006. The prior forty consecutive
dividends were paid on a quarterly basis. Since AmerInst began paying dividends in 1995, our original shareholders have received approximately $38.30 in cumulative dividends per share, which when measured by a total rate of return calculation has
resulted in an effective annual rate of return of approximately 9.7% from the inception of the Company based on a per share purchase price of $25.00 paid by the original shareholders, and using a value of $60.00 per share as of September 30,
2005.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



Inflation



We do not believe our operations have been materially affected by inflation. The potential adverse impacts of inflation
include: (a) a decline in the market value of our fixed term investment portfolio; (b) an increase in the ultimate cost of settling claims which remain unresolved for a significant period of time; and (c) an increase in our operating
expenses. However, we generally hold our fixed term investments to maturity and currently believe that the yield is adequate to compensate us for the risk of inflation. In addition, we expect that any increase from inflation in the ultimate cost of
settling unpaid claims will be offset by investment income earned during the period when the claim is outstanding. Finally, the increase in operating expenses resulting from inflation should generally be matched by similar inflationary increases in
our premium rates.



Market Sensitive Instruments



Market risk generally represents the risk of loss that may result from
potential change in the value of a financial instrument due to a variety of market conditions. Our exposure to market risk is generally limited to potential losses arising from the effects of changes in the level of interest rates on market values
of fixed term holdings and changes in the market values of equity securities. We do not hold or issue derivative financial instruments for either trading or hedging purposes.



(a) Interest Rate Risk.



Interest rate risk results from our holdings in interest-rate-sensitive instruments. We are exposed to potential losses on fixed rate instruments that we
hold arising from changes in the level of interest rates. We are also exposed to credit spread risk resulting from possible changes in the issuers credit rating. To manage our exposure to interest rate risk we attempt to select investments
with characteristics that match the characteristics of our related insurance liabilities. Additionally, we generally only invest in higher-grade interest bearing instruments.



(b) Foreign Exchange Risk.



We only invest in U.S. dollar denominated financial instruments and do not have any exposure to foreign exchange risk.



(c) Equity Price Risk



Equity price risk arises from fluctuations in the value of securities held.
We invest in equity securities in order to diversify our investment portfolio, which our management believes will assist us in achieving our goal of long-term growth of capital and surplus. Our management has adopted investment guidelines that set
out rate of return and asset allocation targets, as well as degree of risk and equity investment restrictions to minimize exposure to material risk from changes in equity prices.



The table below provides information about our investments available for sale that were sensitive to changes in interest
rates at September 30, 2005 and December 31, 2004 respectively.
