NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note A: Summary of Significant Accounting Policies Nature of Operations - Colonial Gas Company, a Massachusetts corporation formed in 1849, is primarily a regulated natural gas distribution utility. The Company serves over 145,000 utility customers in 24 municipalities located northwest of Boston and on Cape Cod. Through its subsidiary, Transgas Inc., the Company also provides over-the-road transportation of liquefied natural gas, propane, and other commodities. Principles of Consolidation - The consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany items have been eliminated in consolidation. Use of Estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Utility Regulation - The Company's utility operations are subject to regulation by the Massachusetts Department of Public Utilities (DPU) with respect to rates charged for natural gas sales and transportation, among other things. The Company's policies conform with generally accepted accounting principles, as applied to regulated public utilities. Utility Property and Non-Utility Property - Utility property and non-utility property are stated at original cost, including labor, materials, taxes and overheads. The amount of interest capitalized as a component of construction overheads amounted to $437,000, $568,000, and $294,000 in 1996, 1995 and 1994, respectively. The original cost of depreciable utility property retired, together with the cost of removal, net of salvage, is charged to accumulated depreciation. Depreciation applicable to the Company's utility property in service is calculated in accordance with depreciation rates as approved by the DPU. The composite depreciation rate is approximately 3.79%. The composite depreciation rate is applied to the utility property balance at the beginning of each year. Depreciation on non-utility property is computed by various methods. Operating Revenues - Operating revenues are accrued based upon the amount of gas delivered to utility customers through the end of the accounting period. Accrued utility revenues of $6,333,000 and $8,924,000, as reported in the Consolidated Balance Sheets at December 31, 1996 and 1995, respectively, represent the accrual of unbilled operating revenues net of related gas costs. The Company's policy is to record lost margins and financial incentives relating to the Company's demand side management (DSM) programs as revenue when earned by the Company and approved by the DPU. Under methodologies approved in 1995 for its residential DSM programs and in 1996 for its commercial and industrial programs, the Company recorded as revenue $1,034,000 of lost margins and $142,000 of financial incentives in 1996 and $900,000 of lost margins and $220,000 of financial incentives in 1995. Unbilled Gas Costs - The Company charges or credits its utility customers for increases or decreases in gas costs from those reflected in its base tariffs by applying a cost of gas adjustment clause (CGAC). In accordance with the CGAC, any under or over recoveries of gas costs are charged or credited to the unbilled gas cost account and recorded as a current asset or liability. Such under or over recoveries are collected or refunded, with interest accrued at the prime rate, in subsequent periods. Pipeline Refunds Due Customers - The Company periodically receives refunds from interstate pipeline companies related to rate adjustments ordered by the Federal Energy Regulatory Commission (FERC). Refunds are returned to utility customers under methods approved by the DPU. Excess Cost of Investments over Net Assets Acquired - This asset arose principally from the pre-1971 acquisitions of utility operations. No amortization has been provided since, in the opinion of management, there has been no diminution in value of the applicable investments. Income Taxes - The Company records deferred income taxes for the income tax effect of the difference between book and tax depreciation and all other temporary book and tax differences, in accordance with Statement of Financial Accounting Standards No. 109 "Accounting for Income Taxes" (SFAS 109). Unamortized investment tax credits, which were allowed under Federal income tax laws prior to 1987, have been deferred and are being amortized as a credit to income tax expense over the estimated service lives of the corresponding assets. Interest and Debt Expense - Interest and debt expense includes interest on long-term debt, interest on short-term notes payable and regulatory interest. As approved by the DPU, regulatory interest is interest income credited on regulatory assets or interest expense charged on regulatory liabilities. Pension Plans - The Company and its subsidiaries have defined benefit pension plans covering substantially all employees. These include two qualified union plans, one qualified plan for non- union employees, and various unqualified individual retirement agreements covering certain key employees and retirees. The Company's funding policy for the qualified plan is to contribute annually an amount at least equal to the normal cost plus a 30- year amortization of the unfunded actuarially calculated accrued liability. Cash and Cash Equivalents - For the purposes of the Consolidated Balance Sheets and Statements of Cash Flows, the Company considers cash investments with an original maturity of three months or less to be cash equivalents. Fair Value of Financial Instruments - In accordance with Statement of Financial Accounting Standards No. 107 "Disclosures About Fair Values of Financial Instruments", the fair value amounts are disclosed below. These fair value amounts are not necessarily indicative of the amounts that the Company could realize in a current market exchange. The carrying amount of cash and cash equivalents and short- term debt approximates fair value. The fair value of long-term debt is estimated based on the rates available to the Company at the end of each respective year for debt of the same remaining maturities. The carrying amount of long-term debt (including current maturities) was $100,418,000 and $81,559,000 as of December 31, 1996 and 1995, respectively. The fair value of long-term debt was $102,016,000 and $89,724,000 as of December 31, 1996 and 1995, respectively. Under current regulatory treatment, any premiums paid to refinance long-term debt, would be recovered over the life of the new debt, and would not have a significant impact on the Company's results of operations. Impairment of Long-Lived Assets - During 1996, the Company adopted Statement of Financial Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of". This statement requires the Company to review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The adoption of this standard did not have a material impact on the Company's financial condition or results of operations. Reclassifications - Reclassifications are made periodically to previously issued financial statements to conform to the current year presentation. Note B: Federal Income Tax The Company records deferred income taxes for the income tax effect of the difference between book and tax depreciation and all other temporary book and tax differences, in accordance with SFAS 109. Prior to October 1981 as approved by the DPU, the Company did not record deferred income taxes but rather "flowed through" tax benefits to utility customers. At December 31, 1996, the Company has a liability of $9,774,000 on the Consolidated Balance Sheet as Deferred Income Taxes - Unfunded and a corresponding unrecovered deferred asset. The liability represents the tax effect of pre- 1981 timing differences for which deferred income taxes had not been provided and was increased in accordance with SFAS 109 for the tax effect of future revenue requirements. The Company is recovering these unfunded deferred taxes from utility customers over the remaining book life of utility property. Federal income tax expense is comprised of the following components: Year Ended December 31, (In Thousands) 1996 1995 1994 Charged (credited) to operations: Current $1,104 $6,455 $2,157 Deferred: Unbilled gas costs 2,929 (1,523) (106) Accelerated depreciation 2,202 2,005 2,167 Demand side management costs 747 (32) 1,115 Pension 449 (38) (840) Recovery of unfunded deferred taxes 398 398 398 Debt expense (53) 848 (21) Transition costs (1) (871) (55) Environmental (246) 22 137 Miscellaneous (260) (79) 84 Amortization of investment tax credits (268) (273) (230) Total 7,001 6,912 4,806 Charged to other income 1,599 477 1,014 Total Federal income tax expense $8,600 $7,389 $5,820 The effective Federal income tax rate and the reasons for the difference from the statutory Federal income tax rate are as follows: 1996 1995 1994 Statutory Federal income tax rate 35% 35% 35% Increases (reductions) in taxes resulting from: Amortization of investment tax credits (1) (1) (1) Recovery of unfunded deferred taxes 	 2 2 2 Miscellaneous items (2) (1) (1) Effective Federal income tax rate 34% 35% 35% Temporary differences which gave rise to the following deferred tax assets (liabilities) are: December 31, (In Thousands) 	 1996 1995 Construction contributions $974 	 $1,060 Other 335 1,468 Total deferred tax assets 1,309 2,528 Accelerated depreciation (39,580) (36,949) Cost of removal (2,792) (2,554) Unbilled gas costs (3,990) (315) Environmental response costs (1,571) (1,865) Demand side management costs (2,659) (1,764) Other (1,467) (2,256) Total deferred tax liabilities (52,059) (45,703) Total deferred taxes $(50,750) $(43,175) Note C: Capital Stock Pursuant to the Company's dividend reinvestment and common stock purchase plan, shareholders can automatically reinvest their cash dividends and can invest optional limited amounts of cash payments in newly issued shares. The Company has authorized and unissued 547,559 shares of Class A Preferred Stock, $25 par value, of which 100,000 shares have been designated a Junior Preferred Stock series and reserved for issuance under the Rights Plan described below, and 370,000 shares of Class B Preferred Stock, $1 par value. A Shareholder Rights Plan provides one right ("Right") to purchase one one-hundredth of a share of the Company's Series A-1 Junior Participating Preferred Stock, par value $25 per share, at a price of $60 per share, subject to adjustment. The Rights expire on December 1, 2003 and only become exercisable, or separately transferable, 10 days after a person or group acquires, or announces an intention to acquire, beneficial ownership of 20% or more of the Company's Common Stock. The Rights are redeemable by the Board at a price of $.01 per Right at any time prior to the expiration of ten days after the acquisition by a person or group of beneficial ownership of 20% or more of the Company's Common Stock. Note D: Long-Term Debt The composition of long-term debt is as follows: December 31, (In Thousands) 1996 1995 First mortgage bonds: 8.86% Series CD due 2001 $ - $6,000 9.40% Series CE due 1997 5,000 10,000 8.05% Series CG due 1999 20,000 20,000 8.80% Series CH due 2022 25,000 25,000 6.85% Series MTA-1 due 2025 10,000 10,000 6.45% Series MTA-2 due 2025 10,000 10,000 6.94% Series MTA-3 due 2026 10,000 - 6.20% Series MTA-4 due 1998 10,000 - 6.88% Series MTA-5 due 2008 10,000 - Total 100,000 81,000 Note payable 418 559 Less: Long-term debt due within one year (5,152) (6,141) Total long-term debt $95,266 $75,418 The aggregate amount of maturities for the years 1997, 1998, 1999, 2000 and 2001 are $5,152,000, $10,164,000, $20,102,000, $0 and $0, respectively. The first mortgage bonds are collateralized by utility property. The Company's first mortgage bond indenture includes, among other provisions, limitations on the issuance of long-term debt, leases and the payment of dividends from retained earnings. The note payable is collateralized by equipment. In September 1995, with the approval of the DPU, the Company established a medium term note (MTN) program which permits the issuance of up to $75 million of MTN's as bonds under its indenture. In 1995, the Company issued $10 million of 30-year bonds (MTA-1) with an average effective interest rate of 6.85% (6.44% during the first ten years and 7.38% in the next twenty years) and $10 million of 30-year bonds (MTA-2) with an average effective interest rate of 6.45% (6.08% during the first ten years and 6.90% in the next twenty years). Both issues of bonds can be redeemed by the holder within a 30 day period at the end of ten years. During 1996, the Company issued three separate medium term notes totalling $30 million at various rates and terms. It is anticipated that the remaining bonds under the MTN program will be issued in 1997. In June 1996, the Company redeemed prior to maturity $5 million of Series CD, 8.86%, first mortgage bonds. Note E: Short-Term Debt In July 1994, the Company established a three-year bank line of credit of $75 million with a consortium of four banks. The bank line of credit allows the Company to borrow on a demand basis up to $75 million, less whatever amount has been borrowed through the Company's gas inventory trust (described below). The line of credit allows the Company the option to borrow under four alternative rates: prime rate, certificate of deposit rate, eurodollar rate (LIBOR), and a competitive bid option. At December 31, 1996, the credit available under the bank line of credit was $11,561,000. The weighted average interest rates for short-term debt were 5.87% and 6.03% at December 31, 1996 and 1995, respectively. The Company has an agreement with a single-purpose Massachusetts trust, the Company's gas inventory trust, under which the Company sells supplemental gas inventory to the trust at the Company's cost. The Company's agreement with the trust requires it to repurchase such inventory at cost when needed and reimburse the trust for expenses incurred to finance the gas inventory. The trust finances such purchases of inventory by borrowing under a bank line of credit with a maximum borrowing commitment of $30 million that is complementary to and on similar terms as the Company's bank line of credit described above. The DPU has approved the inventory trust arrangement and has permitted the cost of such gas inventory, including fees and financing costs, to be recovered through the Company's CGAC. During 1996, 1995 and 1994 approximately $500,000, $662,000 and $504,000, respectively, of interest costs were incurred by the trust. Note F: Lease Obligations The Company leases certain facilities and equipment used in its operations. In accordance with accounting for regulated public utilities, the Company has capitalized certain of these leases and reflects lease payments as rental expense in the periods to which they relate. This capitalization has no impact on the Company's net income. Assets held under capital leases amounted to approximately $7,685,000 and $7,291,000 at December 31, 1996 and 1995, respectively. Accumulated amortization on assets held under capital leases amounted to approximately $5,874,000 and $5,038,000 at December 31, 1996 and 1995, respectively. The most significant agreements which meet the criteria for capital lease classification are a lease which expires in 1998 for a liquefied natural gas storage tank in South Yarmouth, Massachusetts and a lease which expires in 2002 for office facilities in Lowell, Massachusetts. Both leases have fair market renewal options at the end of their initial terms. Total rental expense for the years 1996, 1995 and 1994 approximated $1,493,000, $1,429,000 and $2,049,000, respectively. At December 31, 1996, the future minimum payments (including interest) under the Company's lease agreements are: $881,000 in 1997; $737,000 in 1998; $420,000 in 1999; $300,000 in 2000; $255,000 in 2001; and $100,000 thereafter. Note G: Employee Benefit Plans Savings Plan - The Company sponsors an employee 401(k) Savings Plan. The Company's matching contribution, exclusive of plan administration costs, was $570,000, $459,000 and $387,000 for 1996, 1995 and 1994 respectively. Pension Plans - The Company and its subsidiaries have various defined benefit pension plans covering substantially all employees. Net periodic pension cost is comprised of the following components: Year Ended December 31, (In Thousands) 1996 1995 1994 Benefits earned during the period $1,036 $836 $1,195 Interest cost on projected benefit obligation 3,267 3,279 2,803 Actual return on plan assets (4,710) (5,515) 77 Net amortization and deferral 1,882 2,757 (2,657) Net periodic pension cost $1,475 $1,357 $1,418 Assumptions used in actuarial calculations were as follows: 					 Year Ended December 31, 1996 1995 1994 Weighted average discount rate 7.75% 7.50% 8.50% Future compensation increases 4.00% 4.00% 5.00% Expected long-term rate of return on assets 9.00% 9.00% 9.00% The funded status of the plans at December 31, 1996 and 1995 is as follows: 1996 1995 Assets Accumulated Assets Accumulated Exceed Benefits Exceed Benefits Accumulated Exceed Accumulated Exceed (In Thousands) Benefits Assets Benefits Assets Projected benefit obligations: Vested $(28,612) $(10,381) $(28,993) $(10,388) Nonvested (703) (956) (628) (869) Accumulated (29,315) (11,337) (29,621) (11,257) Due to recognition of future salary increases (4,248) (116) (4,173) (88) Total (33,563) (11,453) (33,794) (11,345) Plan assets at fair value 33,743 7,715 31,168 6,420 Projected benefit obligation: Less than (in 180 (3,738) (2,626) (4,925) excess of) plan assets Unrecognized net (457) 188 1,758 1,232 (gain) loss Unrecognized 1,398 2,020 1,572 1,247 transition amount Unrecognized prior 487 1,064 347 1,493 service cost Additional liability - (3,157) - (3,885) accrued Prepaid (accrued) $1,608 $(3,623) $1,051 $(4,838) pension costs Assets of the employee benefit plans are invested in domestic and international equities, medium-term domestic fixed income securities, international fixed income securities, real estate and other short-term debt instruments. Additional benefits upon retirement were given to 47 employees who accepted the voluntary early retirement program in 1994. The additional cost of $2,537,000 as a result of this program was recorded as a restructuring charge in the fourth quarter of 1994. Postretirement Life and Health Benefit Plan - The Company sponsors a postretirement benefit plan that covers substantially all employees. The plan provides medical, dental and life insurance benefits. The plan is contributory for retirees, with respect to postretirement medical and dental benefits; the plan is noncontributory with respect to life insurance benefits. During 1993, the Company adopted Statement of Financial Accounting Standards No. 106 "Employers" Accounting for Postretirement Benefits Other Than Pensions" (SFAS 106). Prior to 1993, expense was recognized when benefits were paid. In accordance with SFAS 106, the Company began recording the cost for this plan on an accrual basis in 1993. The Company amortizes the transition obligation over a twenty-year period. The Company's cost under this plan for 1996, 1995 and 1994 was $502,000, $672,000 and $694,000 respectively. A regulatory asset of $431,000 was recorded in 1993 representing the excess of postretirement benefits on the accrual basis over the paid amounts for the period of January 1, 1993 until November 1, 1993, the effective date of the DPU's approval of the Company's new rates. Currently, the DPU allows Massachusetts utilities to recover the tax deductible portion of these postretirement benefits. Beginning in 1990, the Company has funded a portion of these costs through the combination of a trust under Section 501(c)(9) of the Internal Revenue Code and separate accounts of the trust under Section 401(h) of the Internal Revenue Code. The following table sets forth the plan's funded status reconciled with the amounts recognized in the Company's financial statements at December 31, 1996 and 1995: (In Thousands) 1996 1995 Accumulated postretirement benefit obligation: Retirees $(3,957) $(3,816) Fully eligible active plan participants (1,033) (1,047) Other active plan participants (1,239) (1,275) Total (6,229) (6,138) Plan assets at fair value 4,563 4,102 Accumulated postretirement benefit obligation in excess of plan assets: (1,666) (2,036) Unrecognized net (gain) from (1,339) (1,310) past experience different from that assumed and from changes in assumptions Unrecognized transition 4,315 4,584 obligation Prepaid postretirement benefit $1,310 $1,238 cost Net periodic postretirement benefit cost included the following components: Year Ended December 31, (In Thousands) 1996 1995 1994 Service cost - benefits attributable to service $137 $145 $202 during the period Interest cost on accumulated 461 505 455 postretirement benefit obligation Actual return on plan assets (507) (639) 143 Net amortization and deferral 410 661 (106) Net periodic postretirement $501 $672 $694 benefit cost For measurement purposes, a 6.5% (4.5% for dental costs) annual rate of increase in the per capita cost of covered health care benefits was assumed for 1997; the rate of increase for medical costs was assumed to decrease gradually from 6.5% to 4.5% in 2001 and remain at that level thereafter. The health care cost trend rate assumption has a significant effect on the amounts reported. To illustrate, increasing the assumed health care cost trend rates by one percentage point in each year would increase the accumulated postretirement benefit obligation as of December 31, 1996 by $755,000 and the aggregate of the service and the interest cost components of net periodic postretirement benefit cost for the year then ended by $71,000. The weighted average discount rate used in determining the accumulated postretirement benefit obligation was 7.75%, 7.5% and 8.5% for 1996, 1995 and 1994, respectively. The expected long-term rate of return on plan assets was 9% for assets in the Section 401(h) accounts and, after estimated taxes, was 6% for assets in the Section 501(c)(9) trust for all years presented. Note H: Other Commitments Long-Term Obligations - The Company has contracts, which expire at various dates through the year 2013, for the acquisition of gas supplies and the storage and delivery of natural gas stored underground. The contracts contain minimum payment provisions which correspond to gas purchases that, in the opinion of management, are not in excess of the Company's requirements. FERC Order 636 Transition Costs - As a result of FERC Order 636, the Company's interstate pipeline service providers have been required to unbundle their supply and transportation services. This unbundling has caused the interstate pipeline companies to incur substantial costs in order to comply with Order 636. These transition costs include four types: (1) unrecovered gas costs (gas costs that had been incurred but not yet recovered by the pipelines when they were providing bundled service to local distribution companies); (2) gas supply realignment costs (the cost of renegotiating existing gas supply contracts with producers); (3) stranded costs (unrecovered costs of assets that can not be assigned to customers of unbundled services); and (4) new facilities costs (costs of new facilities required to physically implement Order 636). Pipelines are expected to be allowed to recover prudently incurred transition costs from customers such as the Company, primarily through a demand charge, after approval by FERC. The Company's additional transition cost liabilities are estimated to range from $4,500,000 to $6,500,000. The Company is recovering these costs from its customers, as approved by the DPU in October 1994. As of December 31, 1996, the Company has recorded on the balance sheet a long-term liability of $4,500,000 ("Accrued Transition Costs") and, based upon rate recovery, has recorded a regulatory asset of $4,500,000 ("Unrecovered Transition Costs Accrued"). Actual transition costs to be incurred depends on various factors, and therefore future costs may differ from the amounts discussed above. Note I: Contingencies Working with the Massachusetts Department of Environmental Protection, the Company is engaged in site assessments and evaluation of remedial options for contamination that has been attributed to the Company's former gas manufacturing site and at various related disposal sites. During 1990, the DPU ruled that Colonial and eight other Massachusetts gas distribution companies can recover environmental response costs related to former gas manufacturing operations over a seven-year period, without carrying costs, through the CGAC. Through December 31, 1996, the Company had incurred environmental response costs of $11,156,000 of which $7,148,000 has been recovered from customers to date. The Company expects to continue incurring costs arising from these environmental matters. As of December 31, 1996, the Company has recorded on the balance sheet a long-term liability of $1,183,000 and, based upon rate recovery, has recorded a corresponding regulatory asset. This amount represents estimated future response costs for these sites based on the Company's preferred methods of remediation. Actual environmental response costs to be incurred depends on various factors, and therefore future costs may differ from the amount currently recorded as a liability. Note J: Quarterly Financial Data (Unaudited) (In Thousands Except Per Share Amounts) Income Utility (Loss)Per Dividends Operating Net Average Paid Per Operating Income Income Common Common Quarter Ended Revenues (Loss) (Loss) Share Share 1996 December 31 $53,869 $9,236 $7,035 $.83 $.325 September 30 15,245 (2,566) (3,580) (.42) .325 June 30 24,237 (689) (2,205) (.26) .325 March 31 77,578 16,213 15,228 1.82 .320 1995 December 31 $56,625 $10,283 $8,530 $1.02 $.320 September 30 14,911 (2,251) (3,932) (.47) .320 June 30 22,760 (925) (3,283) (.40) .320 March 31 70,353 14,467 12,449 1.51 .315 In the opinion of management, the quarterly financial data includes all adjustments, consisting only of normal recurring accruals, necessary for a fair presentation of such information. The Company typically reports profits during the first and fourth quarters of each year while incurring losses during the second and third quarters. This is due to significantly higher natural gas sales during the colder months to satisfy customers' heating needs. Note K: Restructuring Charge In the fourth quarter of 1994, the Company recorded a restructuring charge of $3,185,000 ($1,965,000 after-tax or $.24 per share). This amount includes $2,537,000 for the cost of a voluntary early retirement program which was accepted by 47 employees and $648,000 for costs accrued by the Company in connection with the closure of two retail appliance stores. Note L: Subsequent Event In January 1997, the Company executed definitive agreements with Cabot LNG Corporation (Cabot) to (1) sell a 50% interest in Transgas for $7,000,000 as part of a joint venture and (2) form a separate joint venture owned 50/50 which will lease Colonial's LNG storage tank and related equipment. These joint ventures combine the LNG trucking and storage capabilities of Colonial with the marketing and storage capabilities of Cabot, and are expected to expand the overall utilization of LNG. Completion of the sale of the Transgas interest and implementation of the LNG storage joint venture is subject to certain regulatory approvals. Colonial will recognize a one-time gain, net of taxes, of approximately $.35 per share at the time of the sale, expected to occur in the first half of 1997.

Putnam, III 		Nickolas Stavropoulos President and Chief Executive Officer Executive Vice President- 					Finance, Marketing and 		Chief Financial Officer MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS RESULTS OF OPERATIONS Net Income and Dividends Net income and income per average common share were $16,478,000 ($1.95), $13,764,000 ($1.66) and $11,009,000 ($1.36) for the three years ended December 31, 1996, 1995, and 1994, respectively. Before a restructuring charge of $1,965,000 after-tax or $.24 per share, 1994 net income and income per average common share were $12,974,000 ($1.60). Net income was favorably impacted by colder than 20-year average temperatures in 1996, 1995 and 1994. This is summarized as follows: 1996 1995 1994 Percent colder than 20-year average 3.0% 2.3% 5.0% Percent colder (warmer) than prior year 0.7% (2.5)% (1.3)% Other items which had an impact on net income are discussed in the following sections. Dividends paid per common share were $1.295 in 1996, $1.275 in 1995 and $1.255 in 1994. The Company has paid dividends for 60 consecutive years, and has increased dividends each year for the past 17 years. Operating Revenues Operating revenues were $170,929,000 in 1996, $164,649,000 in 1995 and $166,259,000 in 1994. Operating revenues are impacted by the volumes of gas sold and transported, changes in base rates as approved by the Massachusetts Department of Public Utilities (DPU), and the pass-through of gas costs to customers via a cost of gas adjustment clause (CGAC). The volumes of gas sold are affected by fluctuations in weather and the number of customers being served. Firm sales customers increased by 13,235 over the last three years from 132,187 in December 1993 to 145,422 in December 1996, an increase of 10%, which has added to firm sales volume. The chart below summarizes volumes of gas sold and transported and number of firm sales customers: 1996 1995 1994 (In MMcf) Gas sold Firm 19,563 18,560 18,716 Non-Firm 648 1,148 729 Gas transported Firm 3,918 2,537 6,090 Non-Firm 2,671 3,224 4,185 Total gas sold and transported 26,800 25,469 29,720 (In MMcf) Firm Sales Customers 145,422 141,359 136,636 Operating revenues increased $6,280,000, or 3.8% from 1995 to 1996. This increase resulted from weather that was 0.7% colder than last year and customer growth of 2.9%. Operating revenues decreased $1,610,000, or 1.0%, from 1994 to 1995. This decrease resulted primarily from weather that was 2.5% warmer than the prior year (although 2.3% colder than the 20-year average) partially offset by a growing customer base and additional revenue of $1,120,000 resulting from regulatory approval to recover lost margins and financial incentives associated with the Company's residential conservation programs. Cost of Gas Sold Average cost of gas sold per Mcf was $4.29 in 1996, $4.22 in 1995 and $4.48 in 1994. Cost of gas sold is based upon the sales volumes, the price and mix of gas purchased and used to satisfy demand, and profits on non-firm sales and transportation, which flow back to firm sales customers as a credit through the CGAC. The Company distributes natural gas purchased under long-term contracts as well as gas purchased on the spot market. The following table summarizes the sources of gas purchased by the Company: (In MMcf) 1996 1995 1994 Gas purchased Pipeline 15,115 14,659 14,392 Underground storage 3,346 3,270 3,112 LNG/Other 2,596 2,426 2,390 Total gas purchased 21,057 20,355 19,894 Underground storage consists primarily of spot gas purchased and injected into storage during the summer and fall for use during the following winter. Operating Expenses Operations expense was $31,383,000 in 1996, an increase of $74,000 or 0.2%, from 1995, and $31,309,000 in 1995, a decrease of $1,695,000, or 5.1%, from 1994. In 1996, the Company was able to maintain operations expense at prior years level. The decrease in 1995 was primarily due to less payroll and related benefits as a result of the early retirement program and cost saving initiatives resulting from the Company's self-examination in 1994. Maintenance expense increased $75,000, or 1.7%, in 1996 from 1995 and decreased $673,000, or 13.3%, in 1995 from 1994. The decrease in 1995 was primarily due to cost saving initiatives. Depreciation and amortization expense increased 9.8% or $1,003,000 in 1996 and 10.7% or $990,000 in 1995. The increases in 1996 and 1995 were due to an increase in utility property. Local property and other taxes increased 4.3% in 1996 from 1995 and 4.6% in 1995 from 1994. The increases in 1996 and 1995 were due to higher property taxes and additional property subject to property taxes. A restructuring charge of $3,185,000 ($1,965,000 after-tax or $.24 per share) was recorded during the fourth quarter of 1994. This amount includes $2,537,000 for the cost of a voluntary early retirement program which was accepted by 47 employees and $648,000 for costs accrued by the Company in connection with the closure of two retail appliance stores. Income Taxes Total Federal income and state franchise taxes increased 8.7% or $729,000 in 1996 as a result of a higher level of income. Total Federal income and state franchise taxes increased 42.5% or $2,495,000 in 1995 as a result of more income. Other Operating Income (Expense) Other operating income (expense), net of income taxes was $2,236,000 in 1996, $596,000 in 1995 and $1,336,000 in 1994. Other operating income primarily includes the results of the Company's wholly-owned energy trucking subsidiary (Transgas). Also included are heating and water heating equipment sales and installations. As discussed previously, the Company's retail appliance sales operation was discontinued as of December 31, 1994. Transgas' 1996 financial results were driven by a 68% increase in liquefied natural gas (LNG) hauls leading to a $3,455,000 increase in trucking revenue and a $1,422,000 increase in truck transportation net income. This increase in demand of truck transportation of LNG occurred for most of the year and was primarily due to the colder than normal weather in the fourth quarter of 1995 and the first quarter of 1996. Transgas' 1994 financial results were driven by extremely cold weather in the first quarter of 1994 which generated a significant increase in demand for the truck transportation of liquefied natural gas (LNG) and propane throughout the first three quarters of 1994. Factors affecting the future financial results of Transgas, in addition to the impact of weather variations, include the amount of LNG used by local distribution companies throughout the northeast United States to satisfy requirements of their customers; the price of domestic and Canadian natural gas compared to imported LNG; the continued availability of imported LNG; and the level of construction and major maintenance projects of interstate pipeline companies which drives the demand for portable pipeline services. As discussed in "LNG Joint Ventures", the Company has agreed to sell a 50% interest in Transgas. Effective upon such sale, the Company will be recognizing 50% of the net income of Transgas on an equity basis. Non-Operating Income Non-operating income, net of income taxes, was $757,000 in 1996, $864,000 in 1995 and $565,000 in 1994. Non-operating income includes interest income and miscellaneous other income. Interest and Debt Expense Interest and debt expense decreased $561,000 or 6.1% in 1996. The decrease in 1996 was due to a decrease in interest on long-term debt resulting from the early retirement of higher interest debt in December 1995 offset by increased levels of short-term debt, although at lower short-term interest rates. Interest and debt expense increased 10.2% in 1995 from 1994. The increase in 1995 was due to increased levels of short-term debt and higher short-term interest rates partially offset by a decrease in interest on long-term debt. Effects of Inflation Inflation generally has a negative impact upon the Company's profitability since the rates charged to the Company's utility customers, excluding changes in the cost of gas sold, cannot be increased without formal proceedings before the DPU. Changes in the cost of gas sold are automatically reflected in customer rates pursuant to semi-annual adjustments under the CGAC. In the absence of authorized rate increases, the Company must look to increased productivity and higher sales volumes to offset inflationary increases in its other costs of operations. The present regulatory process permits the Company to earn a rate of return based on the historical cost of utility property without recognition of the current replacement cost. The Company's policy is to file for an increase in rates only when increases in productivity and customers are not sufficient to counteract the impact of inflation. The Company has set a goal to defer its next base rate increase until at least the year 2000. Regulatory Matters Environmental response costs, transition costs and demand side management (DSM) program costs are recovered through the CGAC, as approved by the DPU. The environmental response costs recovered through the CGAC relate to the Company's former gas manufacturing operations, as described under "Environmental Matters". Transition costs relate to FERC approved pipeline charges resulting from Order 636. In addition to full recovery of the installed conservation measures, the Company is allowed to recover, under methodologies approved in 1995 for its residential DSM programs and in 1996 for its commercial and industrial programs resulting lost margins and financial incentives based on the attainment of performance goals. In 1996, the Company recorded as operating revenues $1,034,000 of lost margins and $142,000 of financial incentives associated with the residential and commercial DSM programs and in 1995, recorded as operating revenues $900,000 of lost margins and $220,000 of financial incentives. The Company has made only two requests for base rate increases since 1984. Its most recent request was made in 1993. In response to that request, the DPU approved a base rate increase designed to produce additional revenues of $6.7 million or 4.9% annually, effective November 1, 1993. The Company's goal is to postpone the filing of a request for its next base rate increase until at least the year 2000 through cost-cutting and other measures, such as the LNG joint venture with Cabot LNG Corporation described below, while maintaining an adequate return to shareholders. Under a 1995 industry-wide ruling of the DPU, the Company will be required in its next base rate filing either to present an alternative incentive-based method of pricing or to justify continuation of the traditional cost-of-service/ rate-of-return method. The Company has reviewed alternative incentive-based pricing methods but has not yet determined what method of regulation will be of greatest benefit to its customers and shareholders. During 1996, the DPU ordered all Massachusetts gas companies to offer only "unbundled" gas service to interruptible and special contract customers, as a means of promoting greater competition at the city-gate. Unbundled service separates (i) the part of the service involving procuring the gas and transporting it to the city-gate (i.e. the point where the Company takes gas from the interstate pipeline into its distribution systems); and (ii) the delivery of the gas to the customer's facility through the local distribution system. The Company had previously offered both bundled and unbundled service to interruptible and special contract customers. Since 1993, the Company also has been offering unbundled service as an alternative to its firm commercial and industrial customers. As of December 31, 1996, 19 customers had opted for the firm transportation service, representing less than 2% of the Company's annual firm load. The Company is analyzing methods for making unbundled service viable for the greater number of firm customers, and anticipates DPU rulings containing additional unbundling guidelines in 1997. In its 1996 order, the DPU continued to allow Massachusetts gas companies to price interruptible services at negotiated rates based on the value of that service to the customer. Additionally, Massachusetts gas companies will now be permitted to retain 25% of the net margins earned on interruptible sales, interruptible transportation and capacity release transactions, to the extent those margins exceed thresholds based on previous activity. The Company had previously been allowed to retain 10% of capacity release revenues above an initial threshold of $2,500,000 under its 1993 base rate proceeding. The amounts retained by the Company from interruptible sales, interruptible transportation and capacity release transactions in 1996, 1995 and 1994 totaled $0, $81,000 and $32,000 respectively. All other revenues from these transactions flow back to firm sales customers through the CGAC. Environmental Matters Working with the Massachusetts Department of Environmental Protection, the Company is engaged in site assessments and evaluation of remedial options for contamination that has been attributed to the Company's former gas manufacturing site and at various related disposal sites. During 1990, the DPU ruled that Colonial and eight other Massachusetts gas distribution companies can recover environmental response costs related to former gas manufacturing operations over a seven-year period, without carrying costs, through the CGAC. Through December 31, 1996, the Company had incurred environmental response costs of $11,156,000 of which $7,148,000 has been recovered from customers to date. The Company expects to continue incurring costs arising from these environmental matters. As of December 31, 1996, the Company has recorded on the balance sheet a long-term liability of $1,183,000 and, based upon rate recovery, has recorded a corresponding regulatory asset. This amount represents estimated future response costs for these sites based on the Company's preferred methods of remediation. Actual environmental response costs to be incurred depends on various factors, and therefore future costs may differ from the amount currently recorded as a liability. Accounting Standards Impairment of Long-Lived Assets - During 1996, the Company adopted Statement of Financial Accounting Standards No. 121 "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of". This statement requires the Company to review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The adoption of this standard did not have a material impact on the Company's financial condition or results of operations. LIQUIDITY AND CAPITAL RESOURCES Operating Activities The Company's liquidity is affected by its ability to generate funds from operations and to access capital markets. The Company's operations are seasonal with its cash flow reflecting this seasonality. The Company typically generates approximately 70 percent of its annual operating revenues during the November through April heating season, which results in a high level of cash flow from operations from late winter through early summer. As a result of this seasonality, the Company's liquidity can be affected by significant variations in weather. Short-term borrowings are highest during the fall and early winter months due to the completion of the annual construction program and seasonal working capital requirements.

These joint ventures combine the LNG trucking and storage capabilities of Colonial with the marketing and storage capabilities of Cabot, and are expected to expand the overall utilization of LNG. Completion of the sale of the Transgas interest and implementation of the joint venture is subject to certain regulatory approvals. Colonial will recognize a one-time gain, net of taxes, of approximately $.35 per share at the time of the sale, expected to occur in the first half of 1997.
