WORKING CAPITAL AND CAPITAL EXPENDITURES

During the operating season, the Partnership carries significant receivables and inventories of food and merchandise, as well as payables and payroll-related accruals. Amounts are substantially reduced in non-operating periods. Seasonal working capital needs are met with a revolving credit facility, which is established at a level sufficient to accommodate the Partnership's peak borrowing requirements in April and May as the seasonal parks complete preparations for opening. Revolving credit borrowings are reduced daily with the Partnership's strong positive cash flow during the seasonal operating period.

The Partnership believes that annual park attendance is influenced to some extent by the investment in new attractions from year to year. Capital expenditures are planned on a seasonal basis with the majority of such capital expenditures made in the period from October through May, prior to the beginning of the peak operating season. Capital expenditures made in a calendar year may differ materially from amounts identified with a particular operating season because of timing considerations such as weather conditions, site preparation requirements and availability of ride components, which may result in accelerated or delayed expenditures around calendar yearend.

COMPETITION

In general, the Partnership competes with all phases of the recreation industry within its primary market areas of Cleveland, Detroit, Los Angeles, San Diego, Philadelphia, New Jersey, Minneapolis-St. Paul, and Kansas City, including several other amusement/theme parks in the Partnership's market areas. The Partnership's business is subject to factors generally affecting the recreation and leisure market, such as economic conditions, changes in discretionary spending patterns and weather conditions.

ITEM 6. SELECTED FINANCIAL DATA.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS.

The table below presents certain financial data expressed as a percent of total net revenues and selective statistical information for the periods indicated.

Business Overview

The Partnership generates itsWe generate our revenues primarily from sales of (1) admission to itsour parks, (2) food, merchandise and games inside itsour parks, and (3) hotel rooms, food and other attractions outside itsour parks. The Partnership'sOur principal costs and expenses, which include salaries and wages, advertising, maintenance, operating supplies, utilities and insurance, are relatively fixed and do not vary significantly with attendance. The fixed nature of these costs makes attendance a key factor in the profitability of each park. Results of operations include Knott's Soak City-Palm SpringsGeauga Lake since its acquisition in April of 2004.

The table below presents certain financial data expressed as a percent of total net revenues and Michigan's Adventure since theirselective statistical information for the periods indicated.

Critical Accounting Policies

Management's Discussion and Analysis of Financial Condition and Results of Operations is based upon our consolidated financial statements, which were prepared in accordance with accounting principles generally accepted in the United States of America. These principles require us to make estimates and assumptions during the normal course of business that affect the reported amounts in the consolidated financial statements. Actual results could differ significantly from those estimates under different assumptions and conditions. The following discussion addresses our critical accounting policies, which are those that are most important to the portrayal of our financial condition and operating results and involve a higher degree of judgment and complexity (see Note 2 to our Consolidated Financial Statements of a complete discussion of our significant accounting policies).

Property and Equipment

Buildings, rides and equipment are depreciated over their estimated useful lives on a straight-line basis over each park's operating season. Expenditures made to maintain such assets in their original operating condition are expensed as incurred, and improvements and upgrades are capitalized. The composite method of depreciation is used for groups of assets obtained together in an acquisition.acquisition of a business.

Self-Insurance Reserves

Reserves are recorded for the estimated amounts of guest and employee claims and expenses incurred each period that are not covered by insurance. These estimates are established based upon historical claims data and third-party estimates of settlement costs for incurred claims. These reserves are periodically reviewed for changes in these factors and adjustments are made to assure their adequacy.as needed.

Revenue Recognition

Revenues on multi-day admission tickets are recognized over the estimated number of visits expected for each type of ticket, and are adjusted at the end of each seasonal period. All other revenues are recognized on a daily basis based on actual guest spending at our facilities, or over the park operating season in the case of certain marina dockage revenues.

Results of Operations

2004 vs. 2003

Net revenues forin 2004 increased 6%, or $32.0 million, to $542.0 million. The increase in net revenues was the year ended December 31, 2003 were $510.0result of a 3% increase in combined attendance across our 12 properties (to 12.6 million from 12.2 million in 2003), a 1.4%3% increase over the year ended December 31, 2002. This followedin average in-park guest per capita spending (to $36.59 from $35.48 in 2003), and a 5% increase in out-of-park revenues. The increase in out-of-park revenues was primarily driven by improvement in occupancy levels at our resort hotels at Cedar Point. Excluding results from the acquisition of Geauga Lake, net revenues in 2004 would have increased 2%, or $7.5 million, on a 3% decrease in combined attendance, a 3% increase in average in-park guest per capita spending, and a 4% increase in out-of-park revenues.

In 2004, the addition of Geauga Lake, along with a strong year at Knott's Berry Farm, offset soft attendance numbers at some of our seasonal amusement parks resulting from inconsistent weather during the peak summer months and a moderate capital program. Good weather, together with favorable tourism and pricing trends in the Southern California market, contributed to Knott's strong performance. For the year, combined attendance at our seven amusement parks totaled 11.3 million guests, up 5% from 2003. Excluding the impact of Geauga Lake, combined attendance at our amusement parks would have decreased 1% to 10.6 million. At our five water parks, the comparisons entering 2004 were very difficult following record performances at several of the parks in 2003. For the full year, combined attendance at our five water parks totaled 1.4 million guests, down 11% from 2003, with the majority of that decrease coming at Oceans of Fun in Kansas City, where temperatures stayed well below average al l summer long. The 3% increase in our average in-park guest per capita spending level in 2004 was due to solid improvements in guest spending on admissions and foods, as well as a shift in the mix of attendance away from lower per capita parks, such as our water parks.

Excluding depreciation and all other non-cash charges, total operating costs and expenses in 2004 increased 10%, or $34.7 million, to $369.0 million from $334.3 million in 2003. This increase was largely due to the acquisition of Geauga Lake. Excluding operations at Geauga Lake, total cash operating costs and expenses for 2004 would have increased only 2%, or $6.2 million, from 2003. All operating costs as a percent of revenues remained relatively level between years.

Because we strongly emphasize generating cash flow for distributions to our unitholders, a meaningful measure of our operating results is adjusted EBITDA, which represents earnings before interest, taxes, depreciation, and other non-cash charges and credits. In 2004, adjusted EBITDA decreased 2%, or $2.7 million, to $173.0 million, due entirely to an adjusted EBITDA loss of $4.0 million generated at Geauga Lake during the period subsequent to its acquisition. Excluding the impact of Geauga Lake, adjusted EBITDA would have increased 1%, or $1.3 million, to $177.0 million in 2004, due primarily to increases in average in-park guest per capita spending and out-of-park revenues. The consolidated adjusted EBITDA margin in 2004 decreased to 31.9% from 34.4% in 2003, due almost entirely to the impact of the Geauga Lake operations. On a same park basis, the consolidated EBITDA margin decreased only slightly to 34.2%, due to soft attendance figures at our highest margin park, Cedar Point.

In 2003, we began accounting for unit options using the fair value method under SFAS No. 123, "Accounting for Stock Based Compensation." In 2004, we recorded a $4.5 million non-cash charge for unit options, compared to a charge of $5.9 million in 2003.

In 2002, whenwe recorded a $7.6 million non-cash charge related to the change in fair value of two of our interest rate swap agreements that could not be designated as effective hedges under the applicable accounting rules. In 2004, we recognized a non-cash credit of $4.5 million for the change in fair value of these swap agreements during the year, which compared to a non-cash credit of $2.7 million in 2003. These amounts are aggregated with interest expense in the accompanying table.

After these non-cash items, and interest expense and provision for partnership taxes, both of which were up between years due to the Geauga Lake acquisition, net income for 2004 decreased $7.6 million to $78.3 million, or $1.47 per diluted limited partner unit, from $85.9 million, or $1.67 per unit, in 2003. Excluding the impact of Geauga Lake, net income for 2004 would have increased $5.8 million between years to $91.7 million, or $1.76 per unit.

2003 vs. 2002

Net revenues rosein 2003 increased 1.4%, or $7.1 million, to $510.0 million from $502.9 million from $477.3 million in 2001. Net revenues for 2003 reflect2002. This increase reflects a 3% increase in average in-park guest per capita spending (to $35.48 from $34.50 in 2002), a 1% increase in out-of-park revenues and a 1% decrease in combined attendance across our 11 properties (to 12.2 million from a record 12.4 million in 2002). The increase in out-of-park revenues was from improvements in occupancy levels at our resort hotels at Cedar Point and Knott's Berry Farm.

In 2003, successful capital programs at Cedar Point and Valleyfair, along with a record year at Michigan's Adventure, partially offset attendance declines at Dorney Park and Worlds of Fun resulting from poor weather and the lack of a major new attraction, and an attendance decline at Knott's Berry Farm due to continued soft tourism trends and heavy competition. For the year, combined attendance at our six amusement parks totaled 10.7 million, down less than 2% from last year's record2002's level. At Cedar Point, the addition of Top Thrill Dragster, the world's tallest and fastest roller coaster, contributed to the park's solid performance, while the introduction of the Steel Venom roller coaster at Valleyfair helped generate record revenues at that park. At our five water parks, improved attendance at our California properties, along with a record year at Worlds of Fun's water park, Oceans of Fun, led to a 3% increase in combined attendance to 1.55 million guests. The 3% increase in our overall in- parkin-park guest per capita spending level in 2003 was due to solid improvements in guest spending on admissions and merchandise, as well as a shift in the mix of attendance toward higher per capita parks, such as Cedar Point.

The 5% increase in net revenues in 2002 reflects a 4% increase in combined attendance across our 11 properties to a record 12.4 million guests (from 11.9 million in 2001), a 9% increase in out-of-park revenues, and a slight increase in average in-park guest per capita spending (to $34.50 from $34.41 in 2001). Successful capital programs at both Cedar Point and Knott's Berry Farm, along with strong marketing programs and a record year at Dorney Park, boosted combined attendance at the Partnership's six amusement parks in 2002 by 3% to 10.9 million guests. At Cedar Point, the introduction of a new roller coaster and the addition of the new PEANUTS-themed ice show contributed to the park's strong 2002 performance. The introduction of the Xcelerator roller coaster in July and a strong Halloween Haunt promotion in October led Knott's Berry Farm to a strong second half of 2002. At our five water parks, ideal weather conditions at the Midwest properties, along with a full-year contribution fr om Knott's Soak City-Palm Springs, led to a 15% increase in attendance to 1.5 million guests. Excluding the impact of the new park, combined water park attendance was still up 10% from 2001. The 9% increase in out-of-park revenues was driven primarily by healthy improvement in occupancy levels at Cedar Point's resort hotels.

Cash operating costs and expenses, excluding depreciation and all other non-cash and non-recurring charges, increased less than 1% to $334.3 million in 2003 from $332.8 million in 2002, due to a continued focus at the individual park level to control operating costs during the year. In 2002, these same cash operating costs and expenses increased $8.2 million, or 2.5%, from $324.6 million in 2001, due in part to the mid-year additions of Michigan's Adventure and Knott's Soak City-Palm Springs in 2001. All operating costs as a percent of revenues have remained relatively level between years.

A very meaningful measure of our operating results is adjusted EBITDA, which represents earnings before interest, taxes, depreciation and non-cash and non-recurring charges. In 2003, adjusted EBITDA increased 3% to a record $175.7 million from $170.1 million in 2002, and $152.7 million in 2001, due primarily to increases in average in-park guest per capita spending and out-of-park revenues, as well as each park's ability to control operating costs. The consolidated adjusted EBITDA margin improved to 34.4% in 2003 from 33.8% in 2002, and 32.0% in 2001, due to costs increasing at a slower rate than revenues. (Adjusted EBITDA is not a measure of operating performance computed in accordance with GAAP and should not be considered a substitute for operating income, net income or cash flows from operating activities. In addition, adjusted EBITDA may not be comparable to similarly titled measures of other companies.)

Other non-cash and non-recurring costs in 2003 include several items. In 2003, we began accountinga $5.9 million charge for unit options using the fair value method under SFAS No. 123, "Accounting for Stock Based Compensation," and123. In 2002, we recordedrecognized a $5.9non-cash unit option charge of $4.0 million non-cash charge for the year. Underunder our previous policy of accounting for unit options using the intrinsic value method we recognized non-cash charges of $4.0 million and $11.7 million in 2002 and 2001, respectively,prescribed by Accounting Principles Board (APB) No. 25, "Accounting for Stock Issued to Employees," as we "marked to market" our variable-priced options only. In 2004, under SFAS No. 123 we expect to recognize approximately $5.0 million of non-cash unit option expense.

In 2002, we recorded a $7.6 million non-cash charge in other expense related to the change in fair value of two of our interest rate swap agreements that could not be designated as effective hedges under the applicable accounting rules. In 2003, we recognized a non-cash credit of $2.7 million for the change in fair value of these swap agreements during the year. The $4.9 million remaining balance will reverse into income in 2004 and the first quarter of 2005 as the swaps continue to serve the purpose of leveling our cash interest costs.

In 2002,addition, we recorded a provision of $3.2 million for the estimated portion of the net book value of certain fixed assets that might not be recoverable after they were removed from service.service in 2002.

After these non-cash charges and credits,items, and interest expense and provision for partnership taxes, both of which were comparable between years (except for the effect of interest rate swap accounting), net income for 2003 increased $14.5 million to $85.9 million, compared toor $1.67 per diluted limited partner unit, from $71.4 million, or $1.39 per unit, in 2002 and $57.9 million in 2001.2002.

Liquidity and Capital Resources

We ended 20032004 in sound financial condition in terms of both liquidity and cash flow. The negative working capital ratio (current liabilities divided by current assets) of 3.83.7 at December 31, 20032004 is the result of our highly seasonal business and careful management of cash flow to reduce borrowings. Receivables and inventories are at normally low seasonal levels and credit facilities are in place to fund current liabilities, capital expenditures and pre-opening expenses as required.

Operating Activities

Net cash from operating activities increased $13.2 million, or 10%, to $148.2 million in 2004. This increase was primarily due to normal fluctuations in current liabilities and accrued taxes, offset by a decrease in net income of $7.6 million. The acquisition of Geauga Lake, combined with the timing in payments of liabilities, contributed to the increase in current liabilities and accrued taxes.

Investing Activities

Investing activities consist principally of acquisitions and capital investments we make in our amusement parks and resort properties. During 2003,2004, net cash generated from operationsused for investing activities totaled $135$220.1 million, and new term loan borrowings provided $100 million. We used $40including $144.3 million for the acquisition of Geauga Lake and $75.9 million of capital expenditures, $107compared to $39.8 million to pay down our revolving credit and term loan borrowings, and $88 million to pay cash distributions.

At yearend, we had $331 million of fixed-rate term debt, with staggered maturities ranging from 2004 to 2018, as well as a $180 million revolving credit facility, which is available through March 2007. Borrowings under the revolving credit facility totaled $37.8 million as of December 31, 2003. Of the total term debt, $20.0 million is scheduled to mature prior to December 31, 2004. Based on interest rates in effect at yearend for variable-rate debt and after giving effect to interest rate swap agreements described below, cash interest payments for 2004 would total approximately $22 million, 8% lower than interest paid in 2003. In addition, distributionsThe $36.1 million increase between years in capital expenditures is the result of a moderate capital program for the 2004 atseason and the current annual rateearly timing of $1.76 per unit, would total approximately $89payments on several large capital projects for the 2005 season. We also invested $21 million 1% higher thanin Castaway Bay, our year-round indoor water park resort in Sandusky, Ohio, which opened to the distributions paidpublic in 2003.November 2004.

For the 20042005 operating season, we are investing approximately $25$83 million in capital improvements at our 1112 properties, including expansions to the Soak City water park and Lighthouse Point property at Cedar Point, and the addition of new intermediate-sized thrill ridesworld-class roller coasters at Knott's Berry Farm and WorldsDorney Park, as well as the addition of Fun. In addition, we have also begun construction on a $22 million indoormajor new water park at Cedar Point and a $16 million world-class roller coaster at Knott's, both of which are scheduled to open late in 2004.Geauga Lake. We are optimistic that these investments, as well as other improvements at each of the parks, will generate a high level of public interest and acceptance. However, stable population trends in the parks' market areas and uncontrollable factors, such as weather, the economy, and competition for leisure time and spending, preclude us from anticipating significant long-term increases in attendance. Historically, we have been able to improve our revenues and profitability by continuing to make substantial investments in our parks and resort facilities. This has enabled us to maintain consistently high attendance levels, as well as generate increases in guest per capita spending and revenues from guest accommodations,accommodat ions, while carefully controlling operating and administrative expenses. In 2001

Financing Activities

Net cash provided by financing activities totaled $73.1 million in 2004, compared to net cash utilized of $95.1 million and $91.3 million in 2003 and 2002, however, competitive discountingrespectively. In connection with our acquisition of Geauga Lake in April 2004, we issued $75.0 million of senior notes with terms of seven to eleven years at a fixed rate of 4.72%, and soft economic conditionswe completed an equity offering of 2.6 million limited partner units, which generated net proceeds of $73.3 million. In addition, net revolving credit borrowings totaled $37.7 million in our regional market areas led2004. Cash used in financing activities during the year reflects $20.0 million for scheduled term loan repayments, $92.2 million to virtually flat in-park guestpay cash distributions, and $0.7 million to repurchase the former General Partner's interest in the Partnership.

Capital Resources

At December 31, 2004, we had $387 million of fixed-rate term debt, with staggered maturities ranging from 2005 to 2018, as well as a $180 million revolving credit facility, which is available through March 2007. Borrowings under the revolving credit facility totaled $75.4 million as of December 31, 2004. Of the total term debt, $20 million is scheduled to mature in 2005. Based on interest rates in effect at yearend for variable-rate debt, and after giving effect to interest rate swap agreements described below, cash interest payments for 2005 would total approximately $24-25 million, in line with interest paid in 2004. In addition, cash distributions in 2005, at the recently declared new annual rate of $1.84 per capita spending.unit, would total approximately $98 million, 7% higher than the distributions paid in 2004.

Credit facilities and cash flow from operations are expected to be adequate to meet planned capital expenditures, as well as seasonal working capital needs planned capital expenditures and regular quarterly cash distributions for the foreseeable future.

Contractual Obligations

The following table summarizes certain obligations at December 31, 20032004 (in millions):

1. Represents maturities on long-term debt obligations, plus contractual interest payments on all fixed-rate debt. See Note 3 in "Notes to Consolidated Financial Statements" for further information.
2. Represents contractual obligations in place at yearend for purchase of new rides and attractions. Obligations not denominated in U.S. dollars have been converted based on the exchange rates existing on December 31, 2004.

Off-Balance Sheet Arrangements

We have no significant off-balance sheet financing arrangements.

Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks from fluctuations in interest rates and, from time to time, currency exchange rates on imported rides and equipment. The objective of our financial risk management is to reduce the potential negative impact of interest rate and foreign currency exchange rate fluctuations to acceptable levels. We do not acquire market risk sensitive instruments for trading purposes.

We are party to two interest rate swap agreements that convert $100 million of revolving credit borrowings to fixed-rate obligations averaging 5.82% for a period of 14 more months. In addition, we have converted $100 million of our term debt to variable rates averaging LIBOR plus 0.64% through the use of several swap agreements for a period of 6-155-14 more years. AsThe fair market value of these swaps, which have been designated as fair value hedges on long-term debt, was a net asset of $1.7 million at December 31, 2003,2004, and has been reflected on the balance sheet in "Intangibles and other assets" with a corresponding increase to "Term debt." At December 31, 2004, $285 million of our outstanding long-term debt $269 million representsrepresented fixed-rate debt and $100$175.4 million representsrepresented variable-rate debt. A

After giving effect to our interest rate swap agreements, and assuming an average annual balance on our revolving credit borrowings, the cash flow impact of a hypothetical 1% increaseone percentage point change in the applicable interest rates on our variable-rate debt would increase annual interest expense bybe approximately $1.0$1.7 million as of December 31, 2003.2004.

Impact of Inflation

Substantial increases in costs and expenses could impact our operating results to the extent such increases could possibly not be passed along to our guests. In particular, increases in labor, supplies, taxes and utility expenses could have an impact on our operating results. The majority of our employees are seasonal in nature and are paid hourly rates, which although not tied directly to federal and state minimum wage laws, do follow those wage trends. Historically, we have been able to pass along cost increases to guests through increases in admission, food, merchandise and other prices, and we believe that we will continue to have the ability to do so to a large extent in the future. We believe that the effects of inflation, if any, on our operating results and financial condition have been and will continue to be minor.

Forward Looking Statements

Some of the statements contained in this Annual Report, including the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section, constitute forward-looking statements. These statements may involve risks and uncertainties that could cause actual results to differ materially from those described in such statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to have been correct. Important factors, including general economic conditions, competition for consumer spending, adverse weather conditions, unanticipated construction delays, the absence of historical operating experience for Geauga Lake, and other factors could affect attendance at our parks and cause actual results to differ materially from our expectations.

Notes To Consolidated Financial Statements

(1) Partnership Organization:

Cedar Fair, L.P. (the "Partnership") is a Delaware limited partnership that commenced operations in 1983 when it acquired Cedar Point, Inc., and became a publicly traded partnership in 1987. The Partnership's General Partnergeneral partner is Cedar Fair Management, Company,Inc., an Ohio corporation ownedwhose shares are held by the Partnership's executive managementan Ohio trust (the "General Partner"). The General Partner owns a 0.1%0.001% interest in the Partnership's income, losses and cash distributions, except in defined circumstances, and has full control over all activities of the Partnership. At December 31, 2003,2004, there were 50,673,44453,480,243 outstanding limited partnership units registered on The New York Stock Exchange, net of 1,116,739876,940 units held in treasury.

At a special meeting of limited partners held on June 8, 2004, unitholders approved a plan to allow unitholders to elect the board of directors of the General Partner. Under the approved plan, the Partnership's former general partner, Cedar Fair Management Company, was removed and replaced, and the unitholders elected the members of a staggered board of directors of a new general partner, Cedar Fair Management, Inc. In addition, the partnership agreement was amended to reduce the General Partner's interest in the Partnership from 0.1% to 0.001%, and the new General Partner was granted the authority to implement a unitholders' rights plan, which would allow the board of directors to resist a change or potential change in control of the Partnership if they deem that it is not in the best interest of all unitholders. The equity interest of the former general partner was redeemed by the Partnership for $0.7 million in cash and 89,172 Cedar Fair, L.P. units valued at $2.7 million.

The General Partner may, with the approval of a specified percentage of the limited partners, make additional capital contributions to the Partnership, but is only obligated to do so if the liabilities of the Partnership cannot otherwise be paid or there exists a negative balance in its capital account at the time of its withdrawal from the Partnership. The General Partner, in accordance with the terms of the Partnership Agreement, is required to make regular cash distributions on a quarterly basis of all the Partnership's available cash, as defined.

(2) Summary of Significant Accounting Policies:

The following policies are used by the Partnership in its preparation of the accompanying consolidated financial statements.

Principles of Consolidation The consolidated financial statements include the accounts of the Partnership and its subsidiaries, all of which are wholly owned. All significant intercompany transactions and balances are eliminated in consolidation.

Segment Reporting Although the Partnership manages its parks with a high degree of autonomy, each park offers similar products and services to similar customers. Therefore, the Partnership operates within the single reportable segment of amusement/water parks with accompanying resort facilities.

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 each period. Actual results could differ from those estimates.

Inventories The Partnership's inventories primarily consist of purchased products, such as merchandise and food, for sale to its customers. All inventories are valued at the lower of first-in, first-out (FIFO) cost or market.

Property and Equipment Property and equipment are recorded at cost. Expenditures made to maintain such assets in their original operating condition are expensed as incurred, and improvements and upgrades are capitalized. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets. The composite method is used for the group of assets acquired as a whole in 1983, as well as for the groups of like assets of each subsequent business acquisition. The unit method is used for all individual assets purchased. Depreciation expense totaled $50.1 million in 2004, $44.3 million in 2003, and $41.2 million in 2002, and $42.1 million in 2001.2002.

Under the composite depreciation method, assets with similar estimated lives are grouped together and the several pools of assets are depreciated on an aggregate basis. No gain or loss is recognized on normal retirements of composite assets. Instead, the acquisition cost of a retired asset reduces accumulated depreciation for the composite group. Abnormal retirements of composite assets could result in the recognition of a gain or loss. Management periodically reviews the composite groups to ensure that retirements have not extended the asset lives beyond their estimated remaining economic life.

Under the unit method of depreciation, individual assets are depreciated over their estimated useful lives, with gains and losses on all asset retirements recognized currently in income.

The weighted average useful lives combining both methods are approximately:

Impairment of Long-Lived Assets Effective January 1, 2002, the Partnership adopted Statement of Financial Accounting Standards (SFAS) No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets," which requires that long-lived assets be reviewed for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the assets may not be recoverable. During the first quarter of 2002, the Partnership removed certain fixed assets from service at its parks, and recorded a provision of $3.2 million for the estimated portion of the net book value of these assets that may not be recoverable.

Goodwill Goodwill as of December 31, 20032004 and 20022003 totaled approximately $8.4$9.1 million. Effective January 1, 2002, the Partnership adopted SFAS No. 142, "Goodwill and Other Intangible Assets," which requires that goodwill no longer be amortized, but instead be tested regularly for impairment. An impairment charge would be recognized for the amount, if any, by which the carrying amount of goodwill exceeds its implied fair value. The fair value of a reporting unit and the related implied fair value of its respective goodwill are established through independent fair-market appraisals. This statement did not have a material impact on the consolidated operating results or financial position of the Partnership, as no impairment was identified at the time of adoption, or as of December 31, 2003.has been identified.

Self-Insurance ReservesReserves are recorded for the estimated amounts of guest and employee claims and expenses incurred each period that are not covered by insurance. These estimates are established based upon historical claims data and third-party estimates of settlement costs for incurred claims. These reserves are periodically reviewed for changes in these factors and adjustments are made to assure their adequacy.as needed.

Derivative Financial Instruments The Partnership accounts for the use of derivative financial instruments according to SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities"Activities," and related amendments. For derivative instruments that hedge the exposure of variability in short-term rates, designated as cash flow hedges, the effective portion of the change in fair value of the derivative instrument is reported as a component of "Other comprehensive income (loss)" and reclassified into earnings in the period during which the hedged transaction affects earnings. For derivative instruments that hedge the exposure to changes in the fair value of certain fixed-rate debt, designated as fair value hedges, the effective portion of the change in fair value of the derivative instrument is reported in "Other assets" or "Other liabilities" with a corresponding adjustment to the liability being hedged. For the ineffective portion of a derivative, the change in fair value, if any, is recognized currently in earnings together with the changes in fair value of derivatives not designated as hedges. Derivative financial instruments used in hedging transactions are assessed both at inception and quarterly thereafter to ensure they are effective in offsetting changes in either the fair value or cash flows of the related underlying exposures.

Revenue RecognitionRevenues on multi-day admission tickets are recognized over the estimated number of visits expected for each type of ticket and are adjusted at the end of each seasonal period. All other revenues are recognized on a daily basis based on actual guest spending at our facilities, or over the park operating season in the case of certain marina dockage revenues.

Advertising CostsThe Partnership expenses all costs associated with its advertising, promotion and marketing programs over each park's operating season, including certain costs incurred prior to the season that are amortized over the season. Advertising expense totaled $34.5 million in 2004, $30.8 million in 2003 and $29.9 million in 2002. Amounts incurred through yearend for the following year's advertising programs are included in prepaid expenses.

Income TaxesBecause of its legal structure, the Partnership is not subject to regular corporate income taxes; rather the Partnership's tax attributes (except those of its corporate subsidiaries) are to be included in the individual tax returns of its partners. Neither the Partnership's financial reporting income, nor the cash distributions to unitholders, can be used as a substitute for the detailed tax calculations that the Partnership must perform annually for its partners. Net income from the Partnership is not treated as "passive income" for federal income tax purposes. As a result, partners subject to the passive activity loss rules are not permitted to offset income from the Partnership with passive losses from other sources.

The tax returns of the Partnership are subject to examination by state and federal tax authorities. If such examinations result in changes to taxable income, the tax liability of the partners could be changed accordingly. Only the tax returns of the Partnership's corporate subsidiaries have been examined through March 1999.

Federal and state tax legislation in 1997 provided a permanent income tax exemption to existing "publiclypublicly traded partnerships," such as Cedar Fair, L.P., with new taxes levied on partnership gross income (net revenues less cost of products sold)food, merchandise and games) beginning in 1998. The Partnership recorded provisions of $17.9 million, $17.2 million, and $16.5 milliona tax provision for these federal and state partnership taxes of $18.7 million, $17.9 million, and $17.2 million in 2004, 2003 and 2002, respectively. The provision for income taxes for the Partnership's corporate subsidiaries has not been material in any period presented. The Partnership provides reserves for liabilities that may arise from tax exposures which result from specific positions taken in its tax returns or from tax planning strategies employed to minimize its tax liabilities. Management determines tax exposure items based on positions asserted by tax authorities, as well as management's own assessment of exposures from unasserted items. The calculation of the provision for ta xes involves significant estimates and 2001, respectively.assumptions and actual results could differ from those estimates.

Deferred taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and income tax purposes at the Partnership's corporate subsidiaries. The significant components of deferred tax assets and liabilities as of December 31, 2004 are as follows:

(In thousands)	2004
Deferred tax assets:
Options and deferred compensation	$ 10,026
Accrued expenses	2,119
Gross deferred tax assets	12,145
Deferred tax liabilities:
Depreciation	6,543
Short-period tax liability	4,700
Other, net	78
Gross deferred tax liabilities	11,321
Net deferred tax asset	$ 824

The net current and non-current components of deferred taxes recognized in the consolidated balance sheet are as follows:

(In thousands)	2004
Net current deferred tax asset	$ 743
Net non-current deferred tax asset	81
Net deferred tax asset	$ 824

The net current deferred tax asset amount is included in "Prepaids and other current assets" and the net non-current deferred tax asset amount is included in "Intangibles and other assets" in the accompanying 2004 consolidated balance sheet.

Unit-Based Compensation Prior to 2003, the Partnership accounted for all equity-based compensation awards, including unit options, using the intrinsic value method prescribed by Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to Employees"Employees," and related interpretations. Under APB Opinion No. 25, the Partnership's variable-priced options were "marked to market" over their vesting period whenever the exercise price was lower than the market price of limited partnership units. Approximately $4.0 million and $11.7 million in non-cash compensation expense, with an offsetting credit to partners' equity, was recognized in 2002 and 2001, respectively, under APB Opinion No. 25.

Effective January 1, 2003, the Partnership began to account for unit options under the fair value recognition provisions of SFAS No. 123, "Accounting for Stock-Based Compensation." The Partnership selected the modified prospective method of adoption described in SFAS No. 148, "Accounting for Stock-Based Compensation-Transition and Disclosure." Approximately $4.5 million and $5.9 million in non-cash compensation expense was recognized in 2004 and 2003, respectively, which is the same amount that would have been recognized had the provisions of SFAS No. 123 been applied from its original effective date. In accordance with the modified prospective method of adoption, results for prior years havewere not been restated. Had the Partnership continued to account for options under APB Opinion No. 25, non-cash unit option expense would have been essentially unchanged in 2004 and approximately $13.3 million higher in 2003 compared to the amount recognized under SFAS No. 123.

Had compensation expense for the option plan been determined from inception using the provisions of SFAS No. 123, the effect on the Partnership's net income and earnings per unit in earlier years2002 would have been as follows:

Earnings Per Unit The Partnership has presented earnings per unit amounts for all periods to conform with SFAS No.128, "Earnings Per Share." For purposes of calculating the basic and diluted earnings per limited partner unit, no adjustments have been made to the reported amounts of net income. The unit amounts used are as follows:

	2003	2002	2001
(In thousands except per unit amounts)
Basic weighted average units outstanding	50,615	50,523	50,745
Effect of dilutive units:
Unit options	719	740	368
Diluted weighted average units outstanding	51,334	51,263	51,113
Net income per unit - basic	$1.70	$1.41	$1.14
Net income per unit - diluted	$1.67	$1.39	$1.13
