NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Organization and Basis of Presentation

Organization

The accompanying consolidated financial statements include the accounts of Inergy Holdings, L.P. (“Holdings” or “the Company”), its wholly owned subsidiaries, Inergy Partners, LLC (“Partners”), New Inergy Propane, LLC (“NIP”), Inergy GP, LLC (“GP”), IPCH Acquisition Corp. (“IPCHA”), Wilson Oil Company of Johnston County, Inc. (“Wilson”), Rolesville Gas & Oil Company, Inc. (“Rolesville”) and its controlled subsidiary Inergy, L.P. (“Inergy” or the “Partnership”). IPCHA, Wilson and Rolesville are all subsidiaries created as a result of transactions with Inergy. All significant intercompany transactions, including distribution income, and balances have been eliminated in consolidation.

The consolidated financial statements of the Company include the accounts of Inergy and its subsidiaries, including Inergy Propane, LLC (“Inergy Propane”) and its subsidiary Inergy Sales and Service, Inc. (“Services”), Inergy Acquisition Company, LLC and Inergy Finance Corp. Inergy Partners, LLC (the “Non-Managing General Partner”), a subsidiary of Holdings, owns the Non-Managing General Partner interest in Inergy. Inergy GP, LLC (the “Managing General Partner”), a wholly owned subsidiary of Holdings, has sole responsibility for conducting Inergy’s business and managing Inergy’s operations. The Company is a holding company whose principal business, through its subsidiaries, is its management of and ownership in Inergy.

As of December 31, 2005, Holdings owns an aggregate 10.4% interest in Inergy, inclusive of ownership of the Non-Managing General Partner and Managing General Partner. This ownership is comprised of an approximate 1.1% general partnership interest and a 9.3% limited partnership interest. The Company also owns all of the “incentive distribution rights” provided for in the Inergy partnership agreement, which entitles Holdings to receive increasing percentages, up to 48%, of any cash distributed by Inergy in excess of $0.33 per unit in any quarter.

Nature of Operations

Inergy conducts all of the business activities of the consolidated group and is engaged in the sale, distribution, storage, marketing and trading of propane, natural gas and other natural gas liquids. The retail market is seasonal because propane is used primarily for heating in residential and commercial buildings, as well as for agricultural purposes. Inergy’s operations are primarily concentrated in the Midwest, Northeast, and Southeast regions of the United States.

Basis of Presentation

The financial information contained herein as of December 31, 2005 and for the three-month periods ended December 31, 2005 and 2004 is unaudited. The Company believes this information has been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and Article 10 of Regulation S-X. The Company also believes this information includes all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for the periods then ended. The retail distribution business is largely seasonal due to propane’s primary use as a heating source in residential and commercial buildings. Accordingly, the results of operations for the three month period ended December 31, 2005 is not indicative of the results of operations that may be expected for the entire year.

INERGY HOLDINGS L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements of Inergy Holdings, L.P. and Subsidiaries and the notes thereto included in Form 10-K as filed with the Securities and Exchange Commission for the year ended September 30, 2005.

Conversion Transaction

On April 28, 2005, the Company converted from a Delaware limited liability company (Inergy Holdings, LLC) to a Delaware limited partnership (Inergy Holdings, L.P.). The net income (loss) per limited partner unit and units outstanding presented in the consolidated statements of operations gives effect to the Company’s reorganization as a limited partnership as if it occurred at the beginning of the periods presented.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on net income.

Note 2 – Accounting Policies

Financial Instruments and Price Risk Management

Inergy utilizes certain derivative financial instruments to (i) manage its exposure to commodity price risk, specifically, the related change in the fair value of inventories, as well as the variability of cash flows related to forecasted transactions; (ii) to ensure adequate physical supply of commodity will be available; and (iii) manage its exposure to interest rate risk. Inergy records all derivative instruments on the balance sheet as either assets or liabilities measured at fair value under the provisions of Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities (“SFAS 133”), as amended. Changes in the fair value of these derivative financial instruments are recorded either through current earnings or as other comprehensive income, depending on the type of hedge transaction.

On the date the derivative contract is entered into, Inergy designates the derivative as either a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge), or a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). Inergy documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. Inergy uses regression analysis and the dollar offset method to assess, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, Inergy discontinues hedge accounting prospectively. When hedge accounting is discontinued because it is determined that the derivative no longer qualifies as an effective hedge, Inergy continues to carry the derivative on the balance sheet at its fair value, and recognizes changes in the fair value of the derivative through current period earnings.

10

INERGY HOLDINGS L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Inergy is party to certain commodity derivative financial instruments that are designated as hedges of selected inventory positions, and qualify as fair value hedges, as defined in SFAS 133. Inergy’s overall objective for entering into fair value hedges is to manage its exposure to fluctuations in commodity prices and changes in the fair market value of its inventories as well as to ensure an adequate physical supply will be available. These derivatives are recorded at fair value on the balance sheets as price risk management assets or liabilities and the related change in fair value is recorded to earnings in the current period as cost of product sold. Any ineffective portion of the gain or loss is recognized as cost of product sold in the current period.

Inergy also enters into derivative financial instruments that qualify as cash flow hedges, which hedge the exposure of variability in expected future cash flows attributable to a particular risk. These derivatives are recorded on the balance sheet at fair value as price risk management assets or liabilities. The effective portion of the gain or loss on these cash flow hedges is recorded in other comprehensive income in partner’s capital and reclassified into earnings in the same period in which the hedge transaction closes. Any ineffective portion of the gain or loss is recognized as cost of product sold in the current period.

Furthermore, Inergy has elected to use the special hedge accounting rules in SFAS 133 and hedge the fair value of certain of its inventory positions, whereby the hedged inventory is marked to market. Inventories purchased under energy contracts subsequent to October 25, 2002, and not otherwise designated as being hedged are carried at the lower-of-cost or market.

The cash flow impact of financial instruments is reflected as cash flows from operating activities in the consolidated statements of cash flows.

Revenue Recognition

Sales of propane and other liquids are recognized at the time product is shipped or delivered to the customer. Gas processing and fractionation fees are recognized upon delivery of the product. Revenue from the sale of propane appliances and equipment is recognized at the time of sale or installation. Revenue from repairs and maintenance is recognized upon completion of the service. Revenue from storage contracts is recognized during the period in which it is earned.

Expense Classification

Cost of product sold consists of tangible products sold including all propane and other natural gas liquids sold and all propane-related appliances sold. Operating and administrative expenses consist of all expenses incurred by the Company other than those described in cost of products sold and depreciation and amortization. Certain operating and administrative expenses and depreciation and amortization are incurred in the distribution of product sales, but are not included in cost of product sold. These amounts were $11.6 million and $5.9 million for the three months ended December 31, 2005 and 2004, respectively.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates.

Inventories

Inventories for retail operations, which mainly consist of propane gas and other liquids, are stated at the lower of cost or market and are computed using the average-cost method or on a first-in, first-out basis. Wholesale propane inventories are stated at the lower of cost or market, determined by using the average-cost method unless designated as being hedged by forward sales contracts. Wholesale propane inventories being hedged and carried at market at December 31, 2005 and September 30, 2005 amount to $31.4 million and $85.8 million, respectively.

Inventories consist of (in thousands):

	December 31, 2005		September 30, 2005
Propane gas and other liquids	$	83,777	$	110,085
Appliances, parts and supplies		11,955		7,727
	$	95,732	$	117,812

Shipping and Handling Costs

Shipping and handling costs are recorded as part of cost of products sold at the time product is shipped or delivered to the customer except as discussed in “Expense Classification”.

Identifiable Intangible Assets

The Company has recorded certain identifiable intangible assets, including covenants not to compete, customer accounts, trademarks, deferred financing costs and deferred acquisition costs. Covenants not to compete, customer accounts and trademarks have arisen from the various acquisitions by Inergy. Deferred financing costs represent financing costs incurred in obtaining financing and are being amortized over the term of the debt. Deferred acquisition costs represent costs incurred on acquisitions that Inergy is actively pursuing, most of which relate to the acquisitions completed subsequent to quarter end.

Certain intangible assets are amortized on a straight-line basis over their estimated economic lives, as follows:

	Years
Covenants not to compete	2-10
Deferred financing costs	1-10
Customer accounts	15
Trademarks	-

12

INERGY HOLDINGS L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Trademarks have been assigned an indefinite economic life and are thereafter not being amortized. However, they are subject to an annual impairment evaluation.

Income Per Unit

Basic net income per limited partner unit is computed by dividing net income applicable to partners’ common interest by the weighted average number of units outstanding. Diluted net income per limited partner unit is computed by dividing net income by the weighted average number of units outstanding and the effect of dilutive unit options granted under the long-term incentive plan. The following table presents the calculation of basic and dilutive net income per limited partner unit for the three months ended December 31, 2005, and on a pro-forma basis for the three months ended December 31, 2004, as if the conversion transaction had occurred at the beginning of the period presented (in thousands, except per unit data):

⁽¹⁾ As of December 31, 2004, 597 redeemable partner units were outstanding and included in limited partner units.

Accounting for Unit-Based Compensation

The Company has a unit-based employee compensation plan, which is accounted for under the provisions of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment (“SFAS 123R”), which is a revision of SFAS No. 123, Accounting for Stock-Based Compensation. SFAS 123(R) supersedes APB Opinion No. 25, Accounting for Stock Issued to Employees (“APB 25”), and amends FASB Statement No. 95, Statement of Cash Flows. SFAS No. 123(R) requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values.

INERGY HOLDINGS L.P. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The Company adopted SFAS No. 123(R) on October 1, 2005 using the modified prospective method. Under the modified prospective method, compensation cost is recognized beginning with the effective date (a) for all share-based payments granted after the effective date and (b) for all awards granted to employees prior to effective date of SFAS No. 123(R) that remain unvested as of the effective date. The amount of compensation expense recorded by the Company under the provisions of SFAS 123(R) during the three months ended December 31, 2005 was not significant.

The following table illustrates the effect on net income and net income per limited partner unit as if Inergy had applied the fair value recognition provisions of SFAS No. 123(R) to unit-based employee compensation for the three months ended December 31, 2004. For purposes of pro forma disclosures, the estimated fair value of an option is amortized to expense over the option’s vesting period.

SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information (“SFAS 131”) establishes standards for reporting information about operating segments, as well as related disclosures about products and services, geographic areas, and major customers. Further, SFAS 131 defines operating segments as components of an enterprise for which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and assessing performance. In determining reportable segments under the provisions of SFAS 131, Inergy examined the way it organizes its business internally for making operating decisions and assessing business performance. See Note 7 for disclosures related to the Company’s propane and midstream segments.

Recently Issued Accounting Pronouncements

SFAS No. 151, Inventory Costs, an amendment of ARB No. 43, Chapter 4 (“SFAS 151”), amends the existing standard that provides guidance on accounting for inventory costs and specifically clarifies that abnormal amounts of costs should be recognized as period costs. SFAS 151 is effective for the fiscal year beginning after June 15, 2005. The adoption of SFAS 151 does not have a material effect on the Company’s consolidated financial statements.

SFAS No. 153, Exchanges of Nonmonetary Assets, an amendment of APB Opinion No. 29, Accounting for Nonmonetary Transactions (“SFAS 153”) eliminates the narrow exception for nonmonetary exchanges of similar productive assets and replaces it with a broader exception for exchanges of nonmonetary assets that do not have commercial substance. Further, the amendments made by SFAS 153 are based on the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged. Previously, Opinion No. 29 required that the accounting for an exchange of a productive asset for a similar productive asset or an equivalent interest in the same or similar productive asset should be based on the recorded amount of the asset relinquished. SFAS 153 is effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. Earlier application is permitted for nonmonetary asset exchanges in fiscal periods beginning after the date of issuance. The provisions of SFAS 153 shall be applied prospectively. The adoption of SFAS 153 does not have a material effect on the Company’s consolidated financial statements.

SFAS No. 154, Accounting Changes and Error Corrections (“SFAS 154”) is a replacement of APB Opinion No. 20, Accounting Changes”, and FASB Statement No. 3, Reporting Accounting Changes in Interim Financial Statements. SFAS 154 applies to all voluntary changes in accounting principle and changes the accounting for and the reporting of a change in accounting principle. SFAS 154 requires retrospective application to the prior periods’ financial statements of a voluntary change in accounting principal unless it is impracticable. SFAS 154 is effective for the accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. The adoption of SFAS 154 is not expected to have a material effect of the Company’s consolidated financial statements.

In March 2005, the FASB issued FASB Interpretation No. 47, Accounting for Conditional Asset Retirement Obligations – an interpretation of FASB Statement No. 143 (“FIN 47”). FIN 47 clarifies that the term conditional retirement obligation, as used in FASB Statement No. 143, Asset Retirement Obligations, refers to a legal obligation to perform an asset retirement activity in which the timing or method of settlement, or both, are conditional on a future event that may or may not be within the control of the entity. An entity is required to recognize a liability for the fair value of a conditional asset retirement obligation if the fair value of the liability can be reasonably estimated. FIN 47 is required to be adopted for the fiscal year ended September 30, 2006 and the Company is currently assessing the impact on its financial statements.

EITF 04-13 Accounting for Purchases and Sales of Inventory with the Same Counterparty addresses the accounting for an entity’s sale of inventory to another entity from which it also purchases inventory to be sold in the same line of business. EITF 04-13 concludes that two or more inventory transactions with the same counterparty should be accounted for as a single non-monetary transaction at fair value or recorded amounts based on inventory classifications. EITF 04-13 is effective for new arrangements entered into, and modifications or renewals of existing arrangements, beginning in the first interim or annual reporting period beginning after March 15, 2006. The Company is evaluating the potential impact of EITF 04-13 and does not believe it will have a material effect on its financial position, results of operations and cash flows.

On July 22, 2005, the Company executed a credit agreement (“Bank Facility”) with a bank. The Bank Facility consists of a $15 million working capital revolver for Inergy Holdings, L.P. and a $5 million working capital revolver for IPCH Acquisition Corp. The maturity date of the Bank Facility is July 22, 2008, and is collateralized by certain of our interests in Inergy, L.P. In addition, the Bank Facility is guaranteed by New Inergy Propane, LLC. The prime rate and LIBOR plus the applicable spreads was 6.04% at December 31, 2005, for all outstanding debt under the Bank Facility. The Bank Facility contains several covenants which, among other things, require the maintenance of various financial performance ratios, restrict the payment of distributions to unit holders, and require financial reports to be submitted periodically to the financial institutions.

Inergy’s credit agreement (“Credit Agreement”) consists of a $75 million revolving working capital facility (“Working Capital Facility”) and a $350 million revolving acquisition facility (the “Acquisition Facility”). At December 31, 2005 and September 30, 2005, the balance outstanding under the Credit Agreement included $45.9 million and $20 million, respectively, under the Working Capital Facility. Additionally, at December 31, 2005, Inergy had $36.6 million borrowed under the Acquisition Facility for working capital purposes. The prime rate and LIBOR plus the applicable spreads were between 6.12% and 7.50% at December 31, 2005, and between 6.19% and 7.75% at September 30, 2005, for all outstanding debt under the Credit Agreement. Unused borrowings under the Credit Agreement amounted to $83.0 million and $276.2 million at December 31, 2005 and September 30, 2005, respectively. See Note 8.

At December 31, 2005, the Company was in compliance with all of its debt covenants.

Note 4 – Business Acquisitions

For the quarter ended December 31, 2005, Inergy closed three acquisitions including Atlas Gas Products Inc., Dowdle Gas, and Graeber Brothers Inc. during the first week of October. The aggregate purchase price for these acquisitions, net of cash acquired was $155.1 million. The purchase price allocation for these acquisitions has been prepared on a preliminary basis and changes may occur when additional information becomes available.

Note 5 – Partners’ Capital

On November 14, 2005, a quarterly distribution of $0.27 per limited partner unit was paid to unitholders of record on November 7, 2005 with respect to the fourth fiscal quarter of 2005, which totaled $5.4 million. On July 27, 2005 the board of directors of Inergy Holdings GP, LLC declared a distribution of $0.225 per limited partner unit for the quarter ended June 30, 2005. This distribution, which totaled $0.3 million, was prorated for the portion of the third fiscal quarter Inergy Holdings, L.P. was a public company and was also paid on November 14, 2005.

Inergy Holdings, L.P. will distribute $0.29 per limited partner unit on February 14, 2006, to unitholders of record on February 7, 2006 for a total distribution of $5.8 million with respect to its first fiscal quarter of 2006.

Note 6 – Commitments and Contingencies

Inergy periodically enters into agreements to purchase fixed quantities of liquid propane and distillates at fixed prices with suppliers. At December 31, 2005, the total of these firm purchase commitments was approximately $219.2 million. Inergy also enters into agreements to purchase quantities of liquid propane and distillates at variable prices with suppliers at future dates at the then prevailing market prices. At December 31, 2005, the quantity of these variable purchase commitments was approximately 307.1 million gallons.

At December 31, 2005, Inergy was contingently liable for letters of credit outstanding totaling $25.5 million, which guarantees various transactions.

The Company is periodically involved in litigation proceedings. The results of litigation proceedings cannot be predicted with certainty; however, management believes that the Company does not have material potential liability in connection with these proceedings that would have a significant financial impact on its consolidated financial condition or results of operations.

Inergy utilizes third-party insurance subject to varying retention levels of self-insurance, which management considers prudent. Such self-insurance relates to losses and liabilities primarily associated with workers’ compensation claims and general, product, vehicle, and environmental liability. Losses are accrued based upon management’s estimates of the aggregate liability for claims incurred using certain assumptions followed in the insurance industry and based on past experience.

To the extent they have not already been paid, certain employees of Inergy are entitled to receive up to $1.7 million in aggregate of bonus payments at the end of the subordination periods of Inergy’s Junior and Senior Subordinated Units. As these amounts will only become due if the employees remain employed by Inergy, no amount has been accrued at December 31, 2005.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operation

“Management’s Discussion and Analysis of Financial Condition and Results of Operations” should be read in conjunction with the accompanying consolidated financial statements and “Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Annual Report on From 10-K of Inergy Holdings, L.P. for the year ended September 30, 2005.

The statements in this Quarterly Report on Form 10-Q that are not historical facts, including most importantly, those statements preceded by, or that include the words “may”, “believes”, “expects”, “anticipates” or the negation thereof, or similar expressions, constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements include, but are not limited to, statements that: (i) we believe our wholesale supply, marketing and distribution business complements our retail distribution business, (ii) we expect recovery of goodwill through future cash flows associated with acquisitions, and (iii) we believe that anticipated cash from operations and borrowings under our credit facility will be sufficient to meet our liquidity needs for the foreseeable future. Such forward-looking statements involve risks, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, but are not limited to, the following: weather in our area of operations; market price of propane; availability of financing; changes in, or failure to comply with, government regulations; the costs, uncertainties and other effects of legal and administrative proceedings and other risks and uncertainties detailed in our Securities and Exchange Commission filings. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the Reform Act. We will not undertake and specifically decline any obligation to publicly release the result of any revisions to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect events or circumstances after anticipated or unanticipated events.

Overview

Our cash-generating assets consist of our partnership interests, including incentive distribution rights, in Inergy, L.P. (“Inergy”), a publicly traded Delaware limited partnership, which operates a rapidly growing, geographically diverse retail and wholesale propane supply, marketing and distribution business. Our primary objective is to increase distributable cash flow to our unitholders through our ownership of partnership interests in Inergy. Our incentive distribution rights entitle us to receive an increasing percentage of total cash distributions made by Inergy as it reaches certain target distribution levels and have resulted in significantly increasing cash distributions to us.

Our aggregate partnership interests in Inergy consist of the following:

• a 100% ownership interest in each of the managing general partner of Inergy, which manages Inergy’s business and affairs, and the non-managing general partner of Inergy, which owns an approximate 1.1% general partner interest in Inergy;

• 1,717,551 Inergy common units, 1,093,865 Inergy senior subordinated units and 975,924 Inergy junior subordinated units, representing an aggregate limited partner interest in Inergy of approximately 9.3%;

20

• 769,941 Inergy special units, which are not entitled to a current distribution and will convert into Inergy common units representing limited partnership interests in Inergy at a specified conversion rate upon the commercial operation of the Stagecoach expansion project as described below; and

• all of the incentive distribution rights in Inergy which entitle us to receive increasing percentages, up to a maximum of 48.0%, of any cash distributed by Inergy as certain target distribution levels are reached in excess of $0.33 per Inergy unit in any quarter.

Inergy is a rapidly growing retail and wholesale propane, supply, marketing and distribution business. Inergy also owns and operates a growing midstream operation, including a high performance, multicycle natural gas storage facility (“Stagecoach”) and a natural gas liquids (“NGL”) business in California, which includes natural gas processing, NGL fractionation, NGL rail and truck terminals, bulk storage, trucking and marketing operations. Inergy has grown primarily through acquisitions of retail propane operations. Since the inception of Inergy’s predecessor in 1996 through December 31, 2005, Inergy has acquired 52 companies, 50 propane companies and 2 midstream businesses. Inergy further intends to pursue its growth objectives through, among other things, future acquisitions, maintaining a high percentage of retail sales to residential customers, operating in attractive markets and focusing its operations under established, and locally recognized trade names.

In October 2005, Inergy acquired Atlas Gas Products, Dowdle Gas, Inc., and Graeber Brothers Inc. for a total purchase price of $155.1 million, net of cash acquired. The operating results for these entities are included in our consolidated results of operations from the dates of acquisition.

Since we control the managing general partner of Inergy, we reflect our ownership interest in Inergy on a consolidated basis, which means that our financial results are combined with Inergy’s financial results and the results of our other subsidiaries. The limited partner interests in Inergy not owned by affiliates of the managing general partner are reflected as an expense in our results of operations. We have no separate operating activities apart from those conducted by Inergy, and our cash flows consist of distributions from Inergy on the partnership interests we own. Our consolidated results of operations principally reflect the results of operations of Inergy, and also include our gains on the issuance of Inergy common units, provision for income taxes and interest of non-controlling partners in Inergy’s net income. Accordingly, the discussion of our financial position and results of operations in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” reflects the operating activities and results of operations of Inergy. The historical results of our operations do not reflect the incremental expenses we expect to incur as a result of being a public entity.

Because a substantial portion of Inergy’s propane is used in the weather-sensitive residential markets, the temperatures realized in its areas of operations, particularly during the six-month peak heating season, have a significant effect on its financial performance. As a result, operating income is highest October through March. In any given area, warmer-than-normal temperatures will tend to result in reduced propane use, while sustained colder-than-normal temperatures will tend to result in greater propane use. Therefore, Inergy uses information on normal temperatures in understanding how historical results of operations are affected by temperatures that are colder or warmer than normal and in preparing forecasts of future operations, which are based on the assumption that normal weather will prevail in each of our operating regions. “Heating degree days” are a general indicator of weather impacting propane usage and are calculated for any given period by adding the difference between 65 degrees and the average temperature of each day in the period (if less than 65 degrees).

21

The retail propane business is a “margin-based” business where the level of profitability is largely dependent on the difference between sales prices and product cost. The unit cost of propane is subject to volatile changes as a result of product supply or other market conditions. Propane unit cost changes can occur rapidly over a short period of time and can impact margins as sales prices may not change as rapidly. There is no assurance that Inergy will be able to fully pass on product cost increases, particularly when product costs increase rapidly. Inergy has generally been successful in passing on higher propane costs to our customers and have historically maintained or increased our gross margin per gallon in periods of rising costs.

Inergy believes its wholesale supply, marketing and distribution business complements its retail distribution business. Through its wholesale operations, Inergy distributes propane and also offers price risk management services to propane retailers, resellers and other related businesses as well as energy marketers and dealers, through a variety of financial and other instruments. Inergy engages in derivative transactions to reduce the effect of price volatility on our product costs and to help ensure the availability of propane during periods of short supply.

Results of Operations

The results of operations discussed below principally reflect the activities of Inergy. Because our financial statements represent combined consolidated results of Inergy, our financial statements are substantially similar to Inergy’s. The primary differences in our financial statements include the following amounts in the income statement:

• Our recognition of gain on issuance of units in Inergy. In accordance with Staff Accounting Bulletin No. 51, we recognize an increase in the value of our investment in Inergy when Inergy issues additional common units to third parties at a unit price that exceeds the current carrying value of our investment in Inergy common units. This gain is recognized as income in the period in which the sale to third parties occurs. Historically, Inergy has grown through acquisitions funded in part through the issuance of equity. Because we expect Inergy’s acquisition and related financing activity to continue for the foreseeable future, it is likely that we will continue to recognize gains as a result of future equity issuances by Inergy.

• Provision for Income Taxes. Our provision for income taxes is primarily related to cash flows received by certain of our wholly owned corporate subsidiaries.

• Interest of non-controlling partners in Inergy’s net (income) loss. We adjust our net income by excluding the cash flows distributed on Inergy limited partner units that are not directly or indirectly owned by us. At December 31, 2005, we owned an approximate 9.3% limited partner interest in Inergy together with a 1.1% non-managing general partner interest; and the non-affiliated unitholders owned an 89.6% limited partner interest in Inergy.

22

Three Months Ended December 31, 2005 Compared to Three Months Ended December 31, 2004

Volume. During the three months ended December 31, 2005, we sold 125.1 million retail gallons of propane, an increase of 51.8 million gallons, or 71% over the 73.3 million retail gallons sold during the same three-month period in 2004. The increase in retail sales volume was principally due to the December 2004 acquisition of Star Gas Propane, L.P. (“Star Gas”) and the October 2005 acquisition of Dowdle Gas Inc. (“Dowdle”), as well as the impact from the seven other retail propane companies for which results are only included in the 2004 and 2005 periods subsequent to the date of acquisition. Acquisition-related volume accounted for approximately 56.9 million gallons of this increase. Offsetting the acquisition-related volume increase as well as the colder weather experienced in the 2005 period was a decline in the volume sales at existing locations due to customer conservation as a result of an approximate 22% increase in the average cost of propane in the 2005 period over the 2004 period. Weather was approximately 6% colder in our comparable areas of operations in the three months ended December 31, 2005 as compared to the same period in 2004.

Wholesale gallons delivered during the three months ended December 31, 2005 were 127.5 million gallons, as compared to 125.2 million gallons during the same three-month period in 2004.

Revenues. Revenues for the three months ended December 31, 2005 were $450.3 million, an increase of $192.8 million, or 75%, from $257.5 million during the same three-month period in 2004.

Revenues from retail propane sales were $237.4 million for the three months ended December 31, 2005, an increase of $118.2 million, or 99%, from $119.2 million from the same three-month period in 2004. This increase was primarily the result of $107.0 million of sales related to the Star Gas, Dowdle and other acquisitions together with an increase of approximately $19.9 million due to higher selling prices of propane, which was driven by higher cost per gallon of propane. These increases were partially offset by an $8.7 million decline in revenues as a result of lower retail volume sales at our existing locations as discussed above.

Revenues from wholesale propane sales were $129.9 million for the three months ended December 31, 2005, an increase of $24.7 million or 23%, from $105.2 million from the same three-month period in 2004. Approximately $22.3 million of this increase was attributable to the higher cost of propane, approximately $0.6 million was attributable to acquisition-related volume, and $1.8 million was attributable to volume increases generated in our wholesale propane operations. The higher selling price in our wholesale division resulted primarily from the higher cost of propane.

Revenues from other retail sales, primarily service, appliance, transportation, and distillates, were $49.4 for the three months ended December 31, 2005, an increase of $27.8 million or 129% from $21.6 million during the same three-month period in 2004. This increase was primarily due to the Star Gas and Dowdle acquisitions, which contributed approximately $19.3 million and $4.7 million of this increase, respectively.

Revenues from storage, fractionation and other midstream activities were $33.6 million for the three months ended December 31, 2005, an increase of $22.2 million or 195% from $11.4 million from the same three-month period in 2004. Approximately $13.8 million of this increase was due to higher volumes and sales prices of natural gas, butane, and isobutene. Approximately $8.4 million of this increase was due to the acquisition of the Stagecoach natural gas storage facility.

Cost of Product Sold. Retail propane cost of product sold for the three months ended December 31, 2005 was $161.7 million, an increase of $92.2 million or 133%, from $69.5 million during the same

23

three-month period in 2004. Approximately $65.9 million of this increase was the result of increased volumes from acquisitions, approximately $15.8 million of the increase was attributable to the higher average cost of propane in addition to an increase of $16.1 million due to non-cash charges from derivative contracts associated with retail propane fixed price sales contracts (as discussed below). These increases were partially offset by approximately $5.6 million less cost of product sold as a result of lower retail volume sales at our existing locations as discussed above. The $16.1 million non-cash charge results primarily from a decrease in the market price of propane and delivery of propane under contract to the retail customers in the quarter ended December 31, 2005 since recognizing an approximate $19.4 million non-cash gain in the quarter ended September 30, 2005 on these derivative contracts.

Wholesale propane cost of product sold for the three months ended December 31, 2005 was $123.5 million, an increase of $20.4 million or 20%, from $103.1 million from the same three-month period in 2004. Approximately $18.1 million of this increase was a result of the higher average cost of product, approximately $0.5 million of this increase was a result of acquisition-related volume, and approximately $1.8 million of this increase was the result of higher volumes experienced in our wholesale propane areas of operations.

Other retail cost of product was $29.3 million for the three months ended December 31, 2005, an increase of $17.7 million from $11.6 million from the same three-month period in 2004. This increase was primarily due to acquisition-related volume.

Fractionation, storage, and other midstream cost of product sold was $23.3 million for the three months ended December 31, 2005, an increase of $14.7 million, or 171%, from $8.6 million from the same three-month period in 2004. Approximately $12.8 million of this increase was due to higher volumes and cost of natural gas, butane, and isobutane at the West Coast NGL operations, and the balance was due to acquisition-related volume from the Stagecoach natural gas storage facility.

Our retail cost of product sold consists primarily of tangible products sold including all propane, distillates and other natural gas liquids sold and all propane-related appliances sold. Other costs incurred in conjunction with the distribution of these products are included in operating and administrative expenses and consist primarily of wages to delivery personnel and delivery vehicle costs consisting of fuel costs, repair and maintenance and lease expense. These costs approximated $8.7 million and $4.5 million for the three months ended December 31, 2005 and 2004, respectively. In addition, the depreciation expense associated with the delivery vehicles is reported within depreciation and amortization expense and amounted to $2.9 million and $1.4 million for the three months ended December 31, 2005 and 2004, respectively. Since we include these costs in our operating and administrative expenses rather than in cost of product sold, our results may not be comparable to other entities in our lines of business if they include these costs in cost of product sold.

Gross Profit. Retail propane gross profit was $75.7 million for the three months ended December 31, 2005 compared to $49.7 million in the same three-month period in 2004, an increase of $26.0 million, or 52%. This increase was primarily attributable to an increase in retail gallons sold primarily as a result of acquisitions, which accounted for approximately $41.1 million of the increase, as well as an increase in margin per gallon, which resulted in an increase of approximately $4.1 million. The increase in margin per gallon was primarily the result of our ability to increase our selling prices in certain markets in excess of our increased cost of propane. These increases were partially offset by lower retail

24

propane gross profit of approximately $3.1 million at our existing locations as a result of lower volume sales discussed above. Additionally, the increase was reduced by a $16.1 million charge on non-cash charges from derivative contracts as described above.

Wholesale propane gross profit was $6.4 million for the three months ended December 31, 2005 compared to $2.1 million in the same three-month period in 2004, an increase of $4.3 million or 205%. Approximately $4.2 million of this increase was a result of increased margin per gallon from our existing business, with the balance of the increase attributable to acquisition-related volume.

Other retail gross profit was $20.1 million for the three months ended December 31, 2005 compared to $10.0 million in the same three-month period in 2004, an increase of $10.1 million, or 101%. This increase was due primarily to acquisition-related volume.

Fractionation, storage, and other midstream gross profit was $10.3 million for the three months ended December 31, 2005 compared to $2.8 million in the same three-month period in 2004, an increase of $7.5 million, or 268%. This increase was due primarily to $6.7 million of acquisition-related volume and $0.8 million due to increased volumes and margins to existing customers.

Operating and Administrative Expenses. Operating and administrative expenses increased to $69.0 million in the three months ended December 31, 2005 as compared to $34.8 million in the same three-month period in 2004. This increase was primarily attributable to increases in personnel expenses of $18.3 million, general operating expenses of $11.8 million including insurance, professional services and facility costs, and increased vehicle costs of $4.1 million. These higher costs were driven primarily from acquisitions.

Depreciation and Amortization. Depreciation and amortization increased to $19.7 million in the three months ended December 31, 2005 from $8.8 million during the same period in 2004 as a result of retail propane acquisitions.

Interest Expense. Interest expense increased to $13.6 million in the three months ended December 31, 2005 as compared to $3.8 million during the same three-month period in 2004. Interest expense increased primarily due to an increase in the average debt outstanding including the additional financing related to the acquisition of Star Gas Propane, L.P. and higher average interest rates.

Write-off of Deferred Financing Costs. A charge of $7.0 million was recorded in the three-month period ended December 31, 2004 as a result of the write-off of the deferred financing costs associated with the repayment of the previously existing credit agreement and the 364-day facility. No such charge was recorded in the three months ended December 31, 2005.

Gain on Issuance of Units in Inergy. As a result of issuances of additional Inergy common units at a price per unit greater than our equivalent carrying value, our share of the net assets of Inergy increases. In October 2005, the underwriters of a September 2005 6,500,000 common unit offering exercised a portion of their over-allotment provision and Inergy issued an additional 900,000 common units in a follow-on offering, resulting in proceeds of $24.9 million. During the quarter ended December 31, 2005, the Company recorded a gain of approximately $1.0 million relating to this follow-on offering of Inergy common units. During the three months ended December 31, 2004, Inergy issued additional common units in two separate transactions in connection with Inergy’s acquisition of Star Gas Propane.

25

On December 17, 2004, Inergy issued 3,568,139 Inergy common units to unrelated third parties resulting in net proceeds of approximately $91 million and on December 22, 2004 Inergy issued 4,400,000 Inergy common units in a public offering resulting in net proceeds of $121.3 million. These issuances resulted in a gain of approximately $15.1 million for the quarter ended December 31, 2004.

Provision for Income Taxes. The provision for income taxes is primarily related to certain of our corporate subsidiaries. The provision for income taxes decreased to $0.6 million in the period ended December 31, 2005 from $1.4 million in the same three-month period in 2004. The provision for income taxes of $0.6 million in the three months ended December 31, 2005 was composed of $0.8 million of current income tax expense and $0.2 million of deferred income tax benefit. The 2004 provision for income taxes of $1.4 million was composed of $0.5 million of current income tax and $0.9 million of deferred income taxes.

Interest of non-controlling partners in Inergy’s net (income) loss. We recorded expense of $6.1 million in the three month period ended December 31, 2005 as compared to expense of $9.2 million in the same three month period of 2004 associated with the interests of non-controlling partners in Inergy. The decrease of $3.1 million in expense is primarily the result of a $3.3 million increase in incentive distribution rights received by the Company from Inergy, which had the effect of reducing the interest of non-controlling partners in Inergy’s net income. Net income of Inergy was $10.7 million in the three months ended December 31, 2005 compared to $11.0 million in the same period in 2004. This slight decline also contributed to a lower related expense.

Net Income (loss). Net income was $4.6 million for the three months ended December 31, 2005 compared to net income of $15.1 million for the same three-month period in 2004. The $10.5 million decrease in net income was primarily attributable to a $14.1 million decline in the gain on issuance of units in Inergy partially offset by a $3.1 million decline in expense related to the interest of non-controlling partners in Inergy’s net income and a $0.8 million decline in the provision for income taxes. The remaining slight decrease in net income of $0.3 million was attributable to higher gross profit at Inergy in 2005 being more than offset by the $16.1 million non-cash charge from derivative contracts discussed above, as well as increases in operating and administrative expenses, depreciation and amortization, and interest expense. These increases in expense related items were primarily attributable to acquisitions.

Liquidity and Sources of Capital

Historically, we have relied on distributions from Inergy and on borrowings under our existing credit agreement to fund any cash requirements for our operations. We are, and have been for all periods presented, in compliance with all material financial covenants.

In October 2005, the underwriters of a September 2005 6,500,000 common unit offering exercised a portion of their over-allotment provision and Inergy issued an additional 900,000 common units in a follow-on offering, resulting in proceeds of $24.9 million, net of underwriters’ discounts, commissions, and offering expenses. These funds were used to repay borrowings under the credit agreement.

On January 11, 2006, Inergy, L.P. and its wholly owned subsidiary Inergy Finance Corporation issued $200 million aggregate principal amount of 8  ¹/4% senior unsecured notes due 2016 in a private placement to eligible purchasers. Inergy used the net proceeds of the offering to repay outstanding indebtedness under its revolving acquisition credit facility.

26

Cash flows used in operating activities of $11.2 million for the three months ended December 31, 2005 consisted primarily of the following: net income of $4.6 million; net non-cash charges of $4.6 million, including the interest of non-controlling partners in Inergy’s net income of $6.1 million, depreciation and amortization of $19.7 million, net changes of $(22.2) million in price risk management activities due to a $16.1 million non-cash charge from derivative contracts associated with retail propane fixed price sales, and $1.0 million of other non-cash charges; offset by a decrease in cash flows of $(20.4) million relating to changes in operating assets and liabilities. Net cash used relating to changes in operating assets and liabilities was primarily due to an increase in accounts receivable due to the seasonal nature of the business, offset by a decrease in inventory due to price per gallon decreases as well as utilization of inventory due to the seasonal nature of the business. Cash flows used in operating activities of $10.2 million in the same three-month period in 2004 consisted primarily of the following: net income of $15.1 million, net non-cash charges of $3.7 million relating to the interest of non-controlling partners in Inergy’s net income of $9.2 million, depreciation and amortization of $8.8 million, $7.0 million in write-offs of deferred financing costs related to the repayment of Inergy’s previously existing credit agreement and the 364-day credit facility, net changes of $(7.6) million in price risk management activities, a gain on the issuance of units in Inergy L.P. of $(15.1) million, and $1.4 million of other non-cash charges; and a decrease in cash flows of $29.0 million associated with changes in operating assets and liabilities. The cash used in the changes in operating assets and liabilities is primarily due to an increase in accounts receivable due to acquisition-related revenue growth, the seasonal nature of the business and increased wholesale volumes, an increase in net liabilities from price risk management activities, and an increase in customer deposits as a result of acquisition related activity offset by an increase in accounts payable due to propane purchases.

Cash used in investing activities was $160.4 million in the three months ended December 31, 2005 compared to $597.2 million in the same three month period in 2004. Investing activities for the three months ended December 31, 2005 included a use of cash of $156.0 million, net of cash acquired, for the acquisition of three retail propane companies. Investing activities during the same three-month period in 2004 included a use of cash of $569.9 million for the acquisitions of three retail propane companies, including Star Gas Propane, L.P. Additionally, in the three months ended December 31, 2005 and 2004, we expended $5.3 million and $6.0 million, respectively for additions of property, plant and equipment to accommodate our growing operations. Offsetting these uses of cash in investing activities were the proceeds from sale of property, plant and equipment of $0.9 million and $0.6 million received in the three months ended December 31, 2005 and 2004, respectively.

Cash provided by financing activities was $188.7 million in the three months ended December 31, 2005 and $626.3 million in the same three-month period in 2004. These included net borrowings of $189.4 million and $424.3 million, for the three month periods ended December 30, 2005 and 2004, respectively, under debt agreements, including borrowings and repayments of our revolving working capital and acquisition credit facility and the issuance of senior unsecured notes in the three months ended December 31, 2004. In addition, net proceeds were received from the issuance of Inergy common units of $24.9 million and $212.3 million in the three months ended December 31, 2005 and 2004, respectively. During the three months ended December 31, 2004, the Company received $5.6 million of net proceeds from partners’ contributions. Offsetting these cash sources in the three months ended December 31, 2005 were $24.7 million of distributions and $0.9 million of deferred financing cost payments. Offsetting the cash sources in the three months ended December 31, 2004 was $15.9 million of distributions.

27

The following table summarizes our long-term debt, promissory note, and operating lease obligations as of December 31, 2005 in thousands of dollars:

	Total		Less than 1 year		1-3 years		4-5 years		After 5 years
Aggregate amount of principal to be paid on the outstanding long-term debt	$	780,607	$	76,184	$	33,965	$	245,997	$	424,461
Future minimum lease payments under noncancelable operating leases	$	23,246	$	6,510	$	9,878	$	4,552	$	2,306
Standby letters of credit	$	25,547	$	24,657	$	700	$	190	$	—

We believe that anticipated cash from operations and borrowings under our credit facility and Inergy’s credit facility will be sufficient to meet our liquidity needs for the foreseeable future. If our plans or assumptions change or are inaccurate, or we make any acquisitions, we may need to raise additional capital. We may not be able to raise additional funds or may not be able to raise such funds on favorable terms.

Seasonality

The retail market for propane is seasonal because it is used primarily for heating in residential and commercial buildings. Approximately three-quarters of Inergy’s retail propane volume is sold during the peak heating season from October through March. Consequently, sales and operating profits are generated mostly in the first and fourth calendar quarters of each year.

Description of Credit Facilities

On July 22, 2005, we executed a credit agreement (“Bank Facility”) with a bank. The Bank Facility consists of a $15 million working capital revolver for Inergy Holdings, L.P. and a $5 million working capital revolver for IPCH Acquisition Corp. The maturity date of the Bank Facility is July 22, 2008, and is collateralized by certain of our interests in Inergy, L.P. In addition, the Bank Facility is guaranteed by New Inergy Propane, LLC. The prime rate and LIBOR plus the applicable spreads was 6.04% at December 31, 2005, for all outstanding debt under the Bank Facility. The Bank Facility contains several covenants which, among other things, require the maintenance of various financial performance ratios, restrict the payment of distributions to unit holders, and require financial reports to be submitted periodically to the financial institutions.

Inergy maintains borrowing capacity under a credit facility (“Credit Agreement”), which consists of a $75 million revolving working capital facility (“Working Capital Facility”) and a $350 million revolving acquisition facility (“Acquisition Facility”). The Credit Agreement accrues interest at either prime rate

28

or LIBOR plus applicable spreads, resulting in interest rates between 6.12% and 7.50% at December 31, 2005. At December 31, 2005, borrowings outstanding under the Credit Agreement were $316.5 million, including $45.9 million under the Working Capital Facility and $36.6 million borrowed under the Acquisition Facility for working capital purposes. Of the outstanding Credit Agreement balance of $316.5 million, $244 million is classified as long-term in the accompanying consolidated balance sheet as of December 31, 2005. In January, 2006, Inergy issued $200 million aggregate principal amount of 8  ¹/4% senior unsecured notes due 2016 in a private placement to eligible purchasers and used the net proceeds to repay outstanding indebtedness under the Acquisition Facility.

During each fiscal year beginning October 1, the outstanding balance of the revolving working capital facility in the Credit Agreement must be reduced to $10.0 million or less for a minimum of 30 consecutive days during the period commencing March 1 and ending September 30 of each calendar year.

At Inergy’s option, loans under the Credit Agreement bear interest at either the prime rate or LIBOR (preadjusted for reserves), plus, in each case, an applicable margin. The applicable margin varies quarterly based on its leverage ratio. Inergy also pays a fee based on the average daily unused commitments under the Credit Agreement.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We have long-term debt and a revolving line of credit subject to the risk of loss associated with movements in interest rates. At December 31, 2005, we had floating rate obligations totaling approximately $320.2 million for amounts borrowed under credit agreements and an additional $100.0 million of floating rate obligations as a result of interest rate swap agreements as discussed below.

In the quarter ending March 2005, Inergy entered into four interest rate swap agreements scheduled to mature in December 2014, each designed to hedge $25 million in underlying fixed rate senior unsecured notes, in order to manage interest rate risk exposure. These swap agreements, which expire on the same date as the maturity date of the related senior unsecured notes and contain call provisions consistent with the underlying senior unsecured notes, require the counterparty to pay Inergy an amount based on the stated fixed interest rate on the notes due every six months. In exchange, Inergy is required to make semi-annual floating interest rate payments on the same dates to the counterparty based on an annual interest rate equal to the 6 month LIBOR interest rate plus spreads between 1.95% and 2.20% applied to the same notional amount of $100 million. The swap agreements have been recognized as fair value hedges. Amounts to be received or paid under the agreements are accrued and recognized over the life of the agreements as an adjustment to interest expense. During the three months ended December 31, 2005, Inergy recognized an approximate $1.5 million decrease in the fair market value of the related senior unsecured notes at December 31, 2005, with a corresponding change in the fair value of its interest rate swaps, which are recorded in other liabilities. The fair value of the interest rate swaps was $3.1 million at December 31, 2005.

If the floating rate were to fluctuate by 100 basis points from December 2005 levels, our interest expense would change by a total of approximately $4.2 million per year.

29

Commodity Price, Market and Credit Risk

Inherent in our contractual portfolio are certain business risks, including market risk and credit risk. Market risk is the risk that the value of the portfolio will change, either favorably or unfavorably, in response to changing market conditions. Credit risk is the risk of loss from nonperformance by suppliers, customers or financial counterparties to a contract. Inergy takes an active role in managing and controlling market and credit risk and have established control procedures, which are reviewed on an ongoing basis. Inergy monitors market risk through a variety of techniques, including daily reporting of the portfolio’s position to senior management. Inergy provides for such risks at the time derivative financial instruments are adjusted to fair value and when specific risks become known. Inergy attempts to minimize credit risk exposure through credit policies and periodic monitoring procedures as well as through customer deposits and letters of credit, as deemed appropriate. The counterparties associated with assets from price risk management activities as of December 31, 2005 and 2004 were propane retailers, resellers, energy marketers and dealers.

The propane industry is a “margin-based” business in which gross profits depend on the excess of sales prices over supply costs. As a result, Inergy’s profitability will be sensitive to changes in wholesale prices of propane caused by changes in supply or other market conditions. When there are sudden and sharp increases in the wholesale cost of propane, Inergy may not be able to pass on these increases to our customers through retail or wholesale prices. Propane is a commodity and the price Inergy pays for it can fluctuate significantly in response to supply or other market conditions. Inergy has no control over supply or market conditions. In addition, the timing of cost pass-throughs can significantly affect margins. Sudden and extended wholesale price increases could reduce gross profits and could, if continued over an extended period of time, reduce demand by encouraging Inergy’s retail customers to conserve or convert to alternative energy sources.

Inergy engages in hedging transactions, including various types of forward contracts, options, swaps and futures contracts, to reduce the effect of price volatility on product costs, protect the value of inventory positions, and to help ensure the availability of propane during periods of short supply. Inergy attempts to balance its contractual portfolio by purchasing volumes only when it has a matching purchase commitment from its wholesale customers. However, Inergy may experience net unbalanced positions from time to time which Inergy believes to be immaterial in amount. In addition to its ongoing policy to maintain a balanced position, for accounting purposes Inergy is required, on an ongoing basis, to track and report the market value of its purchase obligations and sales commitments.

Notional Amounts and Terms

The notional amounts and terms of these financial instruments as of December 31, 2005 and September 30, 2005 include fixed price payor for 8.9 million and 12.9 million barrels of propane, respectively, and fixed price receiver for 7.8 million and 14.6 million barrels of propane, respectively. Notional amounts reflect the volume of transactions, but do not represent the amounts exchanged by the parties to the financial instruments. Accordingly, notional amounts do not accurately measure Inergy’s exposure to market or credit risks.

30

Fair Value

The fair value of the derivative financial instruments related to price risk management activities as of December 31, 2005, and September 30, 2005 was assets of $46.6 million and $58.4 million, respectively, and liabilities of $20.7 million and $49.6 million, respectively. All intercompany transactions have been appropriately eliminated. The market prices used to value these transactions reflect management’s best estimate considering various factors including closing exchange and over-the-counter quotations, recent transactions, time value and volatility factors underlying the commitments.

The following table summarizes the change in the unrealized fair value of energy contracts related to Inergy’s risk management activities for the three months ended December 31, 2005 and the same three month period in 2004 where settlement has not yet occurred (in thousands of dollars):

	Three Months Ended
	December 31, 2005			December 31, 2004
Net unrealized gains and (losses) in fair value of contracts outstanding at beginning of period	$	8,784		$	(6,626	)
Net unrealized gain acquired through acquisition during the period		—			1,881
Net change in inventory exchange contracts		23,063			(85	)
Change in fair value of contracts attributable to market movement during the year		(4,004	)		4,983
Less: realized gains recognized		1,998			2,031
Net unrealized gains and (losses) in fair value of contracts outstanding at end of period	$	25,845		$	(1,878	)

Of the outstanding unrealized gain as of December 31, 2005, all contracts had a maturity of one year or less.

Sensitivity Analysis

A theoretical change of 10% in the underlying commodity value would result in a change of approximately $0.2 million in the market value of the contracts as there were approximately 2.1 million gallons of net unbalanced positions at December 31, 2005.

31

Item 4. Controls and Procedures

We maintain controls and procedures designed to ensure that information required to be disclosed in our reports that are filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified by the rules and forms of the SEC, and that information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. An evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as such terms are defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act). Based upon that evaluation, management, including the Chief Executive Officer and the Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were adequate and effective as of December 31, 2005. There have been no changes in the Company’s internal controls over financial reporting (as defined in Rule 13(e)-15 or Rule 15d-15(f) of the Exchange Act) or in other factors during the fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

As Adopted Pursuant to Section 906 of the Sarbanes-Oxley Act of 2002

In connection with the Quarterly Report of Inergy Holdings, L.P. (the “Company”) on Form 10-Q for the period ended December 31, 2005 as filed with the Securities and Exchange Commission on the date hereof (the “Report”), I, John J.
