The First Bancorp, Inc. and Subsidiary

Critical Accounting Policies

Management's discussion and analysis of the Company's financial condition is based on the consolidated financial statements which are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such financial statements requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, Management evaluates its estimates, including those related to the allowance for loan losses, the valuation of mortgage servicing rights, and goodwill. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis in making judgments about the carrying values of assets that are not readily apparent from other sources. Actual results could differ from the amount derived from Management's estimates and assumptions under different assumptions or conditions.

Allowance for Loan Losses. Management believes the allowance for loan losses requires the most significant estimates and assumptions used in the preparation of the consolidated financial statements. The allowance for loan losses is based on Management's evaluation of the level of the allowance required in relation to the estimated loss exposure in the loan portfolio. Management believes the allowance for loan losses is a significant estimate and therefore regularly evaluates it for adequacy by taking into consideration factors such as prior loan loss experience, the character and size of the loan portfolio, business and economic conditions and Management's estimation of potential losses. The use of different estimates or assumptions could produce different provisions for loan losses.

Goodwill. Management utilizes numerous techniques to estimate the value of various assets held by the Company, including methods to determine the appropriate carrying value of goodwill as required under SFAS No. 142. In addition, goodwill from a purchase acquisition is subject to ongoing periodic impairment tests, which include an evaluation of the ongoing assets, liabilities and revenues from the acquisition and an estimation of the impact of business conditions.

Mortgage Servicing Rights. The valuation of mortgage servicing rights is a critical accounting policy which requires significant estimates and assumptions. The Bank often sells mortgage loans it originates and retains the ongoing servicing of such loans, receiving a fee for these services, generally 0.25% of the outstanding balance of the loan per annum. Mortgage servicing rights are recognized when they are acquired through the sale of loans, and are reported in other assets. They are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Management uses an independent firm which specializes in the valuation of mortgage servicing rights to determine the fair value which is recorded on the balance sheet. The most important assumption is the anticipated loan prepayment rate, and increases in prepayment speed results in lower valuations of mortgage servicing rights. The valuation also includes an evaluation for impairment based upon the fair value of the rights, which can vary depending upon current interest rates and prepayment expectations, as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. The use of different assumptions could produce a different valuation. All of the assumptions are based on standards the Company believes would be utilized by market participants in valuing mortgage servicing rights and are consistently derived and/or benchmarked against independent public sources.

Executive Summary

Net income for the nine months ended September 30, 2008 was $11,026,000, an increase of $1,413,000 or 14.7% over net income of $9,613,000 for the comparable period of 2007. The rapid lowering of rates by the Federal Open Market Committee has been very positive for the Company, resulting in funding costs dropping faster than our yield on assets and improving our net interest margin. This, in turn, led to increased net interest income. The Company also saw good growth in earning assets year-to-date. The net interest margin on a tax-equivalent basis increased to 3.27% for the first nine months of 2008 from 3.11% for the same period in 2007. Fully diluted earnings per share for the nine months ended September 30, 2008 were $1.13, a 15.3% increase from the $0.98 reported for the first nine months of 2007.

Net income for the three months ended September 30, 2008 was $3,832,000, an increase of $418,000 or 12.2% over net income of $3,414,000 for the comparable period of 2007. The net interest margin on a tax-equivalent basis increased to 3.31% for the three months ended September 30, 2008 from 3.11% for the same period in 2007. Fully

Asset quality remains good, although the ratio of non-performing assets to total assets increased to 0.74% at September 30, 2008 compared to 0.30% reported at December 31, 2007 and 0.41% at June 30, 2008. Net chargeoffs for the third quarter were $372,000 and stand at $811,000 year to date.

Net Interest Income

Total interest income of $53.7 million for the nine months ended September 30, 2008 is a 1.4% increase from total interest income of $53.0 million in the comparable period of 2007. Total interest expense of $26.4 million for the first nine months of 2008 is an 11.1% decrease from total interest expense of $29.7 million for the first nine months of 2007. Net interest income increased 17.3% or $4.0 million to $27.4 for the nine months ended September 30, 2008, from the $23.3 reported for the same period in 2007.

Total interest income of $17.9 million for the three months ended September 30, 2008 was down 3.5% from the comparable period of 2007. Total interest expense of $8.3 million for the three months ended September 30, 2008 is a 20.4% decrease from total interest expense for the third quarter of 2007. Net interest income increased 18.0% to $9.6 million for the three months ended September 30, 2008, from the $8.2 million reported for the same period in 2007.

The Company's net interest margin on a tax-equivalent basis increased from 3.11% in the first nine months of 2007 to 3.27% for the nine months ended September 30, 2008. For the three months ended September 30, 2008, the Company's net interest margin was 3.31%, an increase from the 3.11% in the same period of 2007. These increases were due to a combination of lower interest rates and growth in earning assets.

Tax-exempt interest income amounted to $3.0 million and $2.8 million for the nine months ended September 30, 2008 and 2007, respectively. For the three months ended September 30, 2008 and 2007, tax-exempt interest income amounted to $1.0 million for both periods. The following table presents the effect of tax-exempt income on the calculation of the net interest margin, using a 35.0% tax rate in 2008 and 2007:

Provision for Loan Losses

A $2,314,000 provision to the allowance for loan losses was made during the first nine months of 2008, compared to a $850,000 provision made for the same period of 2007. For the quarter ended September 30, 2008, a $875,000 provision to the allowance for loan losses was made compared to $300,000 for the same period in 2007. As a result, the allowance for loan losses has increased $1.5 million since year end (net of 2008 net chargeoffs) and stands at 0.86% of loans outstanding, a healthy increase from 0.74% of loans outstanding at December 31, 2007.

While the weakness in the national economy has not hit coastal Maine as hard as many other parts of the country, the Company has seen an increase in the level of past-due and non-performing loans. At this point, this has not translated into a significantly higher level of losses, with net chargeoffs of only $811,000 for the first nine months of 2008, 0.086% of average loans outstanding year-to-date. Given the number of economic uncertainties at this time, however, Management views it prudent to continue to increase the allowance for loan losses.

Non-Interest Income

Non-interest income was $7,550,000 for the nine months ended September 30, 2008, an decrease of 0.7% from the $7,603,000 reported for the first nine months of 2007. This slight decline in non-interest income was due to decreases in fiduciary income that were mostly offset by service charges on deposit accounts and other operating income.

Non-interest income was $2,856,000 for the three months ended September 30, 2008, a decrease of 4.3% from the $2,985,000 reported in the same period for 2007. This decline in non-interest income was primarily due to lower levels of other operating income.

Non-Interest Expense

Non-interest expense of $17,158,000 for the nine months ended September 30, 2008, is an increase of 3.3% compared to non-interest expense of $16,602,000 for the same period in 2007. This increase was attributable to higher employee costs. Expense control continues to be a major factor in our performance. Non-interest expense of $6,284,000 for the three months ended September 30, 2008, is an increase of 4.7% compared to non-interest expense of $6,000,000 for the same period in 2007. This increase was attributable to higher employee costs as well.

Income Taxes

Income taxes on operating earnings were $4,434,000 for the nine months ended September 30, 2008, up from $3,872,000 in the same period a year ago. This is in line with the increase in the Company's level of income before taxes.

In June 2006, the FASB issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109" ("FIN 48"). This statement clarifies the criteria that an individual tax position

Investments

The Company's investment portfolio increased by $39.2 million or 17.7% to $261.1 million between December 31, 2007, and September 30, 2008. At September 30, 2008, the Company's available for sale portfolio had an unrealized loss, net of taxes, of $0.9 million. Between September 30, 2007, and September 30, 2008, the Company's investment portfolio increased by $41.2 million or 18.7%.

Loans

During the first nine months of 2008, loans grew by $40.7 million or 4.4%. The growth in commercial loans was $40.0 million or 9.7% while municipal loans decreased by $8.4 million or 31.9%. The residential mortgage portfolio increased by $7.7 million or 2.0% and home equity lines of credit increased $0.4 million or 0.6% year-to-date. Between September 30, 2007 and September 30, 2008 the loan portfolio increased $69.2 million or 7.8%, as a result of customer demand.

Allowance for Loan Losses

The allowance for loan losses represents the amount available for credit losses inherent in the Company's loan portfolio. Loans are charged off when deemed uncollectible, after giving consideration to factors such as the customer's financial condition, underlying collateral and guarantees, as well as general and industry economic conditions.

Adequacy of the allowance for loan losses is determined using a consistent, systematic methodology, which analyzes the risk inherent in the loan portfolio. In addition to evaluating the collectibility of specific loans when determining the adequacy of the allowance for loan losses, Management also takes into consideration other factors such as changes in the mix and size of the loan portfolio, historic loss experience, the amount of delinquencies and loans adversely classified, and economic trends. The adequacy of the allowance for loan losses is assessed by an allocation process whereby specific loss allocations are made against certain adversely classified loans, and general loss allocations are made against segments of the loan portfolio that have similar attributes. The Company's historical loss experience, industry trends, and the impact of the local and regional economy on the Company's borrowers, are considered by Management in determining the adequacy of the allowance for loan losses.

The allowance for loan losses is increased by provisions charged against current earnings. Loan losses are charged against the allowance when Management believes that the collectibility of the loan principal is unlikely. Recoveries on loans previously charged off are credited to the allowance. While Management uses available information to assess possible losses on loans, future additions to the allowance may be necessary based on increases in non-performing loans, changes in economic conditions, growth in loan portfolios, or for other reasons. Any future additions to the allowance would be recognized in the period in which they were determined to be necessary. In addition, various regulatory agencies periodically review the Company's allowance for loan losses as an integral part of their examination process. Such agencies may require the Company to record additions to the allowance based on judgments different from those of Management.

Credit quality of the commercial portfolios is quantified by a credit rating system designed to parallel regulatory criteria and categories of loan risk. Individual loan officers monitor their loans to ensure appropriate rating assignments are made on a timely basis. Risk ratings and quality of the commercial loan portfolio are also assessed on a regular basis by an independent loan review consulting firm. Ongoing portfolio trend analyses and individual credit reviews to evaluate loan risk and compliance with corporate lending policies are also performed. The level of allowance allocable to each group of risk-rated loans is then determined by applying a loss factor that estimates the amount of probable loss in each category. The assigned loss factor for each risk rating is based upon Management's

Consumer loans, which include residential mortgages, home equity loans/lines, and direct/indirect loans, are generally evaluated as a group based on product type and on the basis of delinquency data and other credit data available due to the large number of such loans and the relatively small size of individual credits. Allocations for these loan categories are principally determined by applying loss factors that represent Management's estimate of inherent losses. In each category, inherent losses are estimated based upon Management's assessment of historical loss data, portfolio characteristics, economic trends, overall market conditions and past experience. In addition, certain loans in these categories may be individually risk-rated if considered necessary by Management.

The other method used to allocate the allowance for loan losses entails the assignment of reserve amounts to individual loans on the basis of loan impairment. Certain loans are evaluated individually and are judged to be impaired when Management believes it is probable that the Company will not collect all of the contractual interest and principal payments as scheduled in the loan agreement. Under this method, loans are selected for evaluation based on internal risk ratings or non-accrual status. A specific reserve is allocated to an individual loan when that loan has been deemed impaired and when the amount of a probable loss is estimable on the basis of its collateral value, the present value of anticipated future cash flows, or its net realizable value.

All of these analyses are reviewed and discussed by the Directors' Loan Committee, and recommendations from these processes provide Management and the Board of Directors with independent information on loan portfolio condition. As a result of these analyses, the Company has concluded that the level of the allowance for loan losses was adequate as of September 30, 2008. As of that date, the balance of $8.3 million was 0.86% of total loans, compared to 0.74% at December 31, 2007 and 0.75% at September 30, 2007. Loans considered to be impaired according to SFAS 114/118 totaled $7.6 million at September 30, 2008 compared to $2.9 million at December 31, 2007. At September 30, 2008, impaired loans with specific reserves totaled $5.6 million compared to $1.3 million at December 31, 2007. The portion of the allowance for loan losses allocated to impaired loans at September 30, 2008, was $1.6 million compared to $0.6 million at December 31, 2007.

In Management's opinion, the level of the Company's allowance for loan losses is adequate. Although the allowance is lower as a percentage of loans than many peers, the Bank's loan portfolio has a higher percentage of residential mortgage loans than peers, which typically reflects a much lower level of credit risk. In coastal Maine, the geographic area which the Company serves, the level of foreclosures has been much lower than in many parts of the United States, and the Company has maintained very high standards when underwriting residential mortgage loans. In addition, the Company's actual historical loan loss experience has been much lower than most of its peer banks, again reflective of our loan portfolio composition.

Non-Performing Assets

At September 30, 2008, loans on non-accrual status totaled $7.6 million, which compares to non-accrual loans of $2.9 million as of December 31, 2007. In addition to loans on non-accrual status at September 30, 2008, loans past due 90 days or more and accruing (calculated on a constant 30-day month basis) totaled $2.9 million which compares to $2.3 million as of December 31, 2007. The Company continues to accrue interest on these loans because it believes collection of the interest is reasonably assured. The level of non-performing loans to total loans was 0.78% at September 30, 2008. While this has increased from 0.31% non-performing loans to total loans at December 31, 2007, it remains well-below the level of non-performing loans for the Bank's peer group, which was 1.56% of total loans as of June 30, 2008..

Goodwill

On January 14, 2005, the Company completed the acquisition of FNB Bankshares of Bar Harbor, Maine, and its subsidiary, The First National Bank of Bar Harbor, which was merged into the Bank. The total value of the transaction was $48.0 million, and all of the voting equity interest of FNB Bankshares was acquired in the transaction. As of December 31, 2007, in accordance with SFAS No. 142, the Company completed its annual review of goodwill and determined there has been no impairment.

Deposits

Borrowed Funds

The Company uses funding from the Federal Home Loan Bank of Boston, the Federal Reserve System, and repurchase agreements, enabling it to grow its balance sheet and its revenues. This funding may also be used to carry out interest rate risk management strategies, and is increased to replace or supplement other sources of funding, including core deposits and certificates of deposit. During the nine months ended September 30, 2008, borrowed funds decreased $52.1 million or 16.5% from December 31, 2007, as a result of the deposit growth previously noted and a shift in strategy to increase the Bank's immediate sources of liquidity.
