PART I — FINANCIAL INFORMATION

Item 1. Financial Statements

Presented herein are the condensed balance sheets of IEA Income Fund XII, L.P. (the “Partnership”) as of June 30, 2006 and December 31, 2005, condensed statements of operations for the three and six months ended June 30, 2006 and 2005, and condensed statements of cash flows for the six months ended June 30, 2006 and 2005, (collectively the “Financial Statements”) prepared by the Partnership without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations, although the Partnership believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these Financial Statements be read in conjunction with the financial statements and the notes thereto included in the Partnership’s December 31, 2005 Annual Report on Form 10-K. These Financial Statements reflect, in the opinion of the Partnership and Cronos Capital Corp. (“CCC”), the general partner, all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the results for the interim periods. The statements of operations for such interim periods are not necessarily indicative of the results for the full year.

The information in this Quarterly Report on Form 10-Q contains certain “forward-looking statements” within the meaning of the securities laws. These forward-looking statements reflect the current view of the Partnership with respect to future events and financial performance and are subject to a number of risks and uncertainties, many of which are beyond the Partnership’s control. All statements, other than statements of historical facts included in this report, including the statements under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” regarding the Partnership’s strategy, future operations, financial position, estimated revenues, projected costs, prospects, plans and objectives of the Partnership are forward-looking statements. When used in this report, the words “would”, “believe”, “anticipate”, “intend”, “estimate”, “expect”, “project”, and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. All forward-looking statements speak only as of the date of this report. The Partnership does not undertake any obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Although the Partnership believes that its plans, intentions and expectations reflected in or suggested by the forward-looking statements made in this report are reasonable, the Partnership can give no assurance that these plans, intentions or expectations will be achieved. Future economic and industry trends that could potentially impact revenues and profitability are difficult to predict.

IEA INCOME FUND XII, L.P.

Notes to Unaudited Condensed Financial Statements

(1) Summary of Significant Accounting Policies

(a)	Nature of Operations
	IEA Income Fund XII, L.P. (the “Partnership”) is a limited partnership organized under the laws of the State of California on August 28, 1991 for the purpose of owning and leasing marine cargo containers worldwide to ocean carriers. The Partnership’s operations are subject to the fluctuations of world economic and political conditions. The Partnership believes that the profitability of, and risks associated with, leases to foreign customers is generally the same as those of leases to domestic customers. The Partnership’s leases generally require all payments to be made in United States currency.
	Cronos Capital Corp. (“CCC”) is the general partner and, with its affiliate Cronos Containers Limited (the “Leasing Company”), manages the business of the Partnership. CCC and the Leasing Company also manage the container leasing business for other partnerships affiliated with CCC.
	The Partnership commenced operations on January 31, 1992, when the minimum subscription proceeds of $2,000,000 were obtained. The Partnership offered 3,750,000 units of limited partnership interest at $20 per unit, or $75,000,000. The offering terminated on November 30, 1992, at which time 3,513,594 limited partnership units had been sold.
	The Partnership has commenced its 14th year of operations, and is in its liquidation phase wherein CCC is focusing its attention on the retirement of the remaining equipment in the Partnership’s container fleet. At June 30, 2006, approximately 30% of the original equipment remained in the Partnership’s fleet. CCC will take several factors into consideration when examining options for the timing of the disposal of the containers. These factors include the impact of a diminishing fleet size and current market conditions on the level of gross lease revenue, and fixed operating costs relative to this revenue. Parallel to these considerations will be a projected increase in expenses for devoting significant resources to the additional reporting and compliance requirements of Section 404 of the Sarbanes Oxley Act of 2002, which addresses a range of corporate governance, disclosure, and accounting issues. These costs may include increased accounting and administrative expenses for additional staffing and outside professional services by accountants and consultants. These additional costs, depending on their materiality, may reduce the Partnership’s results from operations and therefore negatively affect future distributions to the Limited Partners.
(b)	Leasing Company and Leasing Agent Agreement
	A Leasing Agent Agreement exists between the Partnership and the Leasing Company, whereby the Leasing Company has the responsibility to manage the leasing operations of all equipment owned by the Partnership. Pursuant to the Agreement, the Leasing Company is responsible for leasing, managing and re-leasing the Partnership’s containers to ocean carriers and has full discretion over which ocean carriers and suppliers of goods and services it may deal with. The Leasing Agent Agreement permits the Leasing Company to use the containers owned by the Partnership, together with other containers owned or managed by the Leasing Company and its affiliates, as part of a single fleet operated without regard to ownership. Since the Leasing Agent Agreement meets the definition of an operating lease in Statement of Financial Accounting Standards (SFAS) No. 13, it is accounted for as a lease under which the Partnership is lessor and the Leasing Company is lessee.
	The Leasing Agent Agreement generally provides that the Leasing Company will make payments to the Partnership based upon rentals collected from ocean carriers after deducting direct operating expenses and management fees to CCC and the Leasing Company. The Leasing Company leases containers to ocean carriers, under operating leases which are either master leases or term leases (mostly one to five years) and sales-type leases. Master leases do not specify the exact number of containers to be leased or the term that each container will remain on hire but allow the ocean carrier to pick up and drop off containers at various locations, and rentals are based upon the number of containers used and the applicable per-diem rate.

Notes to Unaudited Condensed Financial Statements

(b)	Leasing Company and Leasing Agent Agreement (continued)
	Accordingly, rentals under master leases are all variable and contingent upon the number of containers used. Sales-type leases have fixed payment terms and provide the lessee with a purchase option. The net investment in sales-type leases represents a receivable due from the Leasing Company, net of unearned income. Unearned income, when recognized, is reflected in the Partnership’s statements of operations, providing a constant return on capital over the lease term. Unearned income is recorded as part of the net lease receivable due from the Leasing Company.
(c)	Basis of Accounting
	The Partnership utilizes the accrual method of accounting. Net lease revenue is recorded by the Partnership in each period based upon its leasing agent agreement with the Leasing Company. Net lease revenue is generally dependent upon operating lease rentals from operating lease agreements between the Leasing Company and its various lessees, less direct operating expenses and management fees due in respect of the containers specified in each operating lease agreement.
(d)	Use of Estimates
	The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which requires the Partnership to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.
	The most significant estimates included within the financial statements are the container rental equipment estimated useful lives and residual values, and the estimate of future cash flows from container rental equipment operations, used to determine the carrying value of container rental equipment in accordance with SFAS No. 144. Considerable judgment is required in estimating future cash flows from container rental equipment operations. Accordingly, the estimates may not be indicative of the amounts that may be realized in future periods. As additional information becomes available in subsequent periods, recognition of an impairment of the container rental equipment carrying values may be necessary based upon changes in market and economic conditions.
(e)	Container Rental Equipment
	Container rental equipment is depreciated over a 15-year period using the straight-line basis to its salvage value, estimated to be 10% of its original equipment cost. Depreciation policies are also evaluated to determine whether subsequent events and circumstances warrant revised estimates of useful lives.
	In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” container rental equipment is considered to be impaired if the carrying value of the asset exceeds the expected future cash flows from related operations (undiscounted and without interest charges). If impairment is deemed to exist, the assets are written down to fair value. An analysis projecting future cash flows from container rental equipment operations is prepared annually, or upon material changes in market conditions. Current and projected utilization rates, per-diem rental rates, direct operating expenses, fleet size and container disposals are the primary variables utilized by the analysis. Additionally, the Partnership evaluates future cash flows and potential impairment by container type rather than for each individual container, and as a result, future losses could result for individual container dispositions due to various factors, including age, condition, suitability for continued leasing, as well as the geographical location of containers when disposed. There were no impairment charges to the carrying value of container rental equipment for the six-month periods ended June 30, 2006 and 2005.

(f)	Allocation of Net Income or Loss, Partnership Distributions and Partners’ Capital Accounts
	Net income or loss has been allocated between the general and limited partners in accordance with the Partnership Agreement. The Partnership Agreement generally provides that CCC shall at all times maintain at least a 1% interest in each item of income or loss, including the gain arising from the sale of containers. The Partnership Agreement further provides that the gain arising from the sale of containers be allocated first to the partners with capital account deficit balances in an amount sufficient to eliminate any deficit capital account balance. Thereafter, the Partnership’s gains arising from the sale of containers are allocated to the partners in accordance with their share of sale proceeds distributed. The Partnership Agreement also provides for income (excluding the gain arising from the sale of containers) for any period, be allocated to CCC in an amount equal to that portion of CCC’s distributions in excess of 1% of the total distributions made to both CCC and the limited partners of the Partnership for such period, as well as other allocation adjustments.
	Actual cash distributions differ from the allocations of net income or loss between the general and limited partners as presented in these financial statements. Partnership distributions are paid to its partners (general and limited) from distributable cash from operations, allocated 95% to the limited partners and 5% to CCC. Distributions of sales proceeds are allocated 99% to the limited partners and 1% to CCC. The allocations remain in effect until such time as the limited partners have received from the Partnership aggregate distributions in an amount equal to their capital contributions plus a 10% cumulative, compounded (daily), annual return on their adjusted capital contributions. Thereafter, all Partnership distributions will be allocated 85% to the limited partners and 15% to CCC. Cash distributions from operations to CCC in excess of 5% of distributable cash will be considered an incentive fee and will be recorded as compensation to CCC, with the remaining distributions from operations charged to partners’ capital.
	Upon dissolution, the assets of the Partnership will be sold and the proceeds thereof distributed as follows: (i) all of the Partnership’s debts and liabilities to person’s other than CCC or the limited partners shall be paid and discharged; (ii) all of the Partnership’s debts and liabilities to CCC and the limited partners shall be paid and discharged; and (iii) the balance of such proceeds shall be distributed to CCC and the limited partners in accordance with the positive balances of CCC and the limited partners’ capital accounts. CCC shall contribute to the Partnership, if necessary, an amount equal to the lesser of the deficit balance in its capital account at the time of such liquidation, or 1.01% of the excess of the Limited Partners’ capital contribution to the Partnership over the capital contributions previously made to the Partnership by CCC, after giving effect to the allocation of income or loss arising from the liquidation of the Partnership’s assets.
(g)	Financial Statement Presentation
	These financial statements have been prepared without audit pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) have been condensed or omitted pursuant to such rules and regulations, although the Partnership believes that the disclosures are adequate to make the information presented not misleading. It is suggested that these financial statements be read in conjunction with the financial statements and accompanying notes in the Partnership’s December 31, 2005 Annual Report on Form 10-K.
	The interim financial statements presented herewith reflect, in the opinion of management, all adjustments of a normal recurring necessary to present fairly the results for the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results to be expected for the full year.

Net Lease and Other Receivables Due from Leasing Company

Net lease and other receivables due from the Leasing Company are determined by deducting direct operating payables and accrued expenses, base management fees payable, and reimbursed administrative expenses payable to CCC and its affiliates from the rental billings earned by the Leasing Company under operating leases and sales-type leases to ocean carriers for the containers owned by the Partnership as well as proceeds earned from container disposals. Net lease and other receivables at June 30, 2006 and December 31, 2005 were as follows:

	June 30,			December 31,
	2006			2005
Gross lease and other receivables	$	553,927		$	733,378
Sales-type lease receivable (net of unearned income)		—			18,342

		374,844			446,537
Net lease and other receivables	$	179,083		$	305,183

On December 1, 2004, the Leasing Company, on behalf of the Partnership, amended a term lease agreement with one lessee to include a bargain purchase option in exchange for the lessee’s continued lease of these older containers and their eventual sale. As a result of the amendment, the Partnership reclassified the term lease agreement as a sales-type lease, recorded a sales-type lease receivable and recognized the sale of 532 on-hire containers that were subject to the amended term lease agreement. The sales-type lease expired on March 31, 2006, at which time the lessee exercised its bargain purchase option to acquire the containers subject to the sales-type lease.

(3)	Net Lease Revenue
	Net lease revenue is determined by deducting direct operating expenses, base management fees and reimbursed administrative expenses to CCC and its affiliates from the rental revenue earned by the Leasing Company under operating leases to ocean carriers for the containers owned by the Partnership. Net lease revenue for the three and six-month periods ended June 30, 2006 and 2005 were as follows:

	Three Months Ended				Six Months Ended
	June 30,		June 30,		June 30,		June 30,
	2006		2005		2006		2005

Net lease revenue	$	287,857	$	480,618	$	628,621	$	963,277

(4)	Operating Segment
	An operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and about which separate financial information is available. Management operates the Partnership’s container fleet as a homogenous unit and has determined that as such, it has a single reportable operating segment.
	The Partnership derives revenues from marine dry cargo and refrigerated containers used by its customers in global trade routes. As of June 30, 2006, the Partnership operated 3,143 twenty-foot, 1,551 forty-foot and 79 forty-foot high-cube marine dry cargo containers, as well as 82 twenty-foot and 6 forty-foot marine refrigerated containers. A summary of gross lease revenue earned by the Leasing Company on behalf of the Partnership, by product, for the three and six-month periods ended June 30, 2006 and 2005 follows:

	Three Months Ended				Six Months Ended
	June 30,		June 30,		June 30,		June 30,
	2006		2005		2006		2005
Dry cargo containers	$	337,696	$	562,087	$	740,027	$	1,131,884
Refrigerated containers		47,948		94,420		106,296		190,760
Total	$	385,644	$	656,507	$	846,323	$	1,322,644

Due to the Partnership’s lack of information regarding the physical location of its fleet of containers when on lease in the global shipping trade, the Partnership believes that it does not possess discernible geographic reporting segments as defined in SFAS No. 131 (“SFAS 131”), “Disclosures about Segments of an Enterprise and Related Information.”

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

     The following discussion of the Partnership’s historical financial condition and results of operations should be read in conjunction with the Partnership’s December 31, 2005 Annual Report on Form 10-K and the financial statements and the notes thereto appearing elsewhere in this report.

Market Overview

     Market conditions during the second quarter of 2006 for the Partnership’s dry cargo and refrigerated containers reflected an improvement in demand when compared to the first quarter of the year, which traditionally has been a period of reduced activity within the container shipping and leasing industries. Other factors that affected the container leasing industry during the first quarter, including the purging of excess equipment by the shipping lines from their leased container fleets and ongoing structural changes within the shipping industry had less of an impact on the container leasing market and the Partnership’s operations during the second quarter. During the second quarter, industry experts deemed the container shipping industry stronger than originally forecasted. In particular, the concern that additional cargo capacity created by the delivery of new containerships would outpace demand was alleviated in the short term by the fact that the new, larger containerships were utilized to update existing trade routes, as opposed to launching new services. Additionally, shipping lines are reported to have reduced their investment in new containers during the first half of 2006 due to the rising price of new containers, as well as a reduction in earnings stemming from lower freight rates, higher fuel costs and rising interest rates. By the end of the second quarter, certain economic trends, including yet higher energy costs, coupled with rising interest rates and higher consumer prices in the US and other countries, appeared to support a slowing in the growth of the global economy.

     In future periods, economic growth and global container trade are expected to have less of an impact on the Partnership’s operations when compared to the effects of CCC’s efforts to retire the remaining equipment in the Partnership’s container fleet. One of the Partnership’s original investment objectives was to realize the residual value of its containers after the expiration of their useful lives, estimated to be between 12 to 15 years after placement in leased service.

     Utilization of the Partnership’s dry cargo container fleet averaged 93% and 92% for the three and six-month periods ended June 30, 2006, respectively. In comparison, dry cargo container utilization rates averaged 96% for both the three and six-month periods ended June 30, 2005. The utilization rate for the Partnership’s refrigerated container fleet measured 80% and 79% for the three and six-month periods ended June 30, 2006, respectively. In comparison, refrigerated container utilization rates for the three and six-month periods ended June 30, 2005 averaged 86% and 85%, respectively. During the same three and six-month periods ended June 30, 2005, the container leasing industry was benefiting from one of the most favorable periods in its 35-year-plus history, resulting in higher levels of demands for existing containers and lower levels of off-hire container inventories than during the same periods in 2006.

     During the second quarter of 2006, the secondary market demand for used containers remained favorable. Higher utilization levels contributed to lower container inventories, resulting in a decrease in the volume of containers available for sale and a slight increase in container sale prices. Changes in future inventory levels, as well as significant fluctuations in new container prices, could adversely impact sales proceeds realized on the sale of the Partnership’s remaining containers. The sale of the Partnership’s off-hire containers, in accordance with one of its aforementioned original investment objectives, has positively affected the Partnership’s results from operations, contributing to high utilization levels in recent periods, minimizing storage and other inventory-related costs incurred for its off-hire containers, as well as realizing gains from the sale of its containers.

     Since December 31, 2005, the price of a new 20-foot dry cargo container increased from approximately $1,500 to approximately $2,000 by the end of July 2006. This rise is primarily attributable to a recent upswing in the price of raw materials used in the production of containers. Most leasing companies reduced their dry cargo container purchasing during the last half of 2005, took delivery of virtually no additional dry cargo containers during the fourth quarter of 2005, and continued to curtail their investment in new containers during the first half of 2006, anticipating a decline in new container prices by the end of 2006. Although the Partnership no longer purchases

12

new containers, the price of new containers indirectly contributed to the Partnership’s results of operations by influencing the level of lease per-diems for existing older containers, as well as container sale prices realized upon their eventual disposal.

     The per-diem rate for the Partnership’s dry cargo containers decreased approximately 12% for both the three and six-month periods ending June 30, 2006, when compared to the same periods in the prior year. The average per-diem rate for the Partnership’s refrigerated cargo containers during the three and six-month periods ending June 30, 2006 decreased approximately 4% and 3%, respectively, when compared to the same periods in the prior year. The lease market for older dry and refrigerated cargo containers remains competitive and, therefore, will be subject to significant pricing pressures in subsequent periods.

     A significant number of new containerships built under various shipbuilding programs are expected to be delivered during the third quarter of 2006. A record number of 1,992 containerships are expected to be delivered in 2006, an increase of 50% from the prior year. The additional capacity has recently contributed to lower freight rates as shipping lines position themselves to ensure that they can fill their new capacity, resulting in reduced profitability for the shipping lines that, in turn, could have adverse implications for container leasing companies. Overcapacity and falling freight rates, combined with soaring oil prices and rising interest rates, are contributing to a challenging outlook for the shipping industry. The Partnership, CCC and the Leasing Company continue to monitor the aging of lease receivables, collections and the credit exposure to various existing and new customers. The financial impact of losses from shipping lines may eventually influence the demand for leased containers, as some shipping lines may experience financial difficulties, consolidate, or become insolvent.

Results of Operations

     Pursuant to the Limited Partnership Agreement of the Partnership, all authority to administer the business of the Partnership is vested in CCC. A Leasing Agent Agreement (“Agreement”) exists between the Partnership and the Leasing Company, whereby the Leasing Company has the responsibility to manage the leasing operations of all equipment owned by the Partnership. Pursuant to the Agreement, the Leasing Company is responsible for leasing, managing and re-leasing the Partnership’s containers to ocean carriers and has full discretion over which ocean carriers and suppliers of goods and services it may deal with. The Agreement permits the Leasing Company to use the containers owned by the Partnership, together with other containers owned or managed by the Leasing Company and its affiliates, as part of a single fleet operated without regard to ownership.

     The primary component of the Partnership’s results of operations is net lease revenue. Net lease revenue is determined by deducting direct operating expenses, management fees and reimbursed administrative expenses from gross lease revenues billed by the Leasing Company from the leasing of the Partnership’s containers. Net lease revenue is directly related to the size, utilization and per-diem rental rates of the Partnership’s fleet. Direct operating expenses are direct costs associated with the Partnership’s containers. Direct operating expenses may be categorized as follows:

• Activity-related expenses, including agent and depot costs such as repairs, maintenance and handling.

• Inventory-related expenses for off-hire containers, comprising storage and repositioning costs. These costs are sensitive to the quantity of off-hire containers as well as the frequency at which containers are re-delivered.

• Legal and other expenses, including legal costs related to the recovery of containers and doubtful accounts, insurance and provisions for doubtful accounts.

     At June 30, 2006, approximately 30% of the original equipment remained in the Partnership’s fleet, as compared to approximately 39% at December 31, 2005. The following table summarizes the composition of the Partnership’s fleet (based on container type) at June 30, 2006.

Three Months Ended June 30, 2006 Compared to the Three Months Ended June 30, 2005

     Net lease revenue was $287,857 for the three months ended June 30, 2006 compared to $480,618 for the same period in the prior year. The decline was primarily due to a $269,802 decrease in gross rental revenue (a component of net lease revenue) when compared to the same period in the prior year. Gross rental revenue was primarily impacted by the Partnership’s smaller fleet size, and a 12% decline in the average dry cargo per-diem rental rate, when compared to the same three-month period in the prior year. Rental equipment operating expenses (a component of net lease revenue) declined $42,381 and was attributable to the Partnership’s declining fleet size. The Partnership’s average fleet size and utilization rates for the three-month periods ended June 30, 2006 and 2005 were as follows:

	Three Months Ended
	June 30,			June 30,
	2006			2005
Fleet size (measured in twenty-foot equivalent units (TEU))
Dry cargo containers		6,894			9,751
Refrigerated containers		101			205
Average utilization rates
Dry cargo containers		93	%		96	%
Refrigerated containers		80	%		86	%

     Depreciation expense of $287,245 for the three months ended June 30, 2006 declined by $109,639 when compared to the corresponding period in 2005, a direct result of the Partnership’s aging and declining fleet size.

     Other general and administrative expenses amounted to $43,609 for the three-month period ended June 30, 2006, increasing by $5,266 when compared to the same period in 2005, due primarily to higher professional fees for audit service.

14

     Net gain on disposal of equipment for the three months ended June 30, 2006 was $112,910, an increase of $39,397, compared to the corresponding period in 2005. The Partnership disposed of 469 containers, compared to 491 containers during the same three-month period in 2005. The Partnership continued to dispose of additional containers during 2006 in response to its original investment objective, to realize the residual value of its containers after the expiration of their useful lives. The net gain on container disposals in the three-month period ended June 30, 2006 was a result of the volume of container disposals, in addition to other various factors, including, the age, condition, suitability for continued leasing, as well as the geographical location of the containers when disposed. These factors will continue to influence the amount of sales proceeds received and the related gain or loss on container disposals.

     The level of the Partnership’s container disposals in subsequent periods, as well as the price of steel, new container prices and the current leasing market’s impact on sales prices for existing older containers such as those owned by the Partnership, will also contribute to fluctuations in the net gain or loss on disposals. There were no reductions to the carrying value of container rental equipment due to impairment during the three-month periods ended June 30, 2006 and 2005.

Six Months Ended June 30, 2006 Compared to the Six Months Ended June 30, 2005

     Net lease revenue was $628,621 for the six months ended June 30, 2006 compared to $963,277 for the same period in the prior year. The decline was primarily due to a $474,085 decrease in gross rental revenue (a component of net lease revenue), when compared to the same period in the prior year. Gross rental revenue was primarily impacted by the Partnership’s smaller fleet size, and a 12% decline in the average dry cargo per-diem rental rate, when compared to the same six-month period in the prior year. Rental equipment operating expenses (a component of net lease revenue) declined $79,325 and was attributable to the Partnership’s declining fleet size. The Partnership’s average fleet size and utilization rates for the six-month periods ended June 30, 2006 and 2005 were as follows:

	Six Months Ended
	June 30,			June 30,
	2006			2005
Fleet size (measured in twenty-foot equivalent units (TEU))
Dry cargo containers		7,415			10,099
Refrigerated containers		109			224
Average utilization rates
Dry cargo containers		92	%		96	%
Refrigerated containers		79	%		85	%

     Depreciation expense of $606,304 for the six months ended June 30, 2006 declined by $219,304 when compared to the corresponding period in 2005, a direct result of the Partnership’s aging and declining fleet size.

     Other general and administrative expenses amounted to $82,714 for the six-month period ended June 30, 2006, an increase of $10,715 when compared to the same period in 2005.

     Net gain on disposal of equipment for the six months ended June 30, 2006 was $171,056, as compared to a net gain of $65,424 for the corresponding period in 2005. The Partnership disposed of 1,404 containers during the first six months of 2006, compared to 1,007 containers during the same six-month period in 2005. The Partnership continued to dispose of additional containers during 2006 in response to its original objective, to realize the residual value of its containers after the expiration of their useful lives. The net gain on container disposals in the six-month period ended June 30, 2006, was a result of various factors, including the volume of disposed containers, the age, condition, suitability for continued leasing, as well as the geographical location of the containers when disposed.

Liquidity and Capital Resources

     During the Partnership’s first 10 years of operations, the Partnership’s primary objective was to generate cash flow from operations for distribution to its limited partners. Aside from the initial working capital reserve retained from the gross subscription proceeds (equal to approximately 1% of such proceeds), the Partnership relied primarily on container rental receipts to meet this objective as well as to finance current operating needs. No credit lines are maintained to finance working capital. Commencing in 2002, the Partnership’s 11th year of operations, the Partnership began focusing its attention on the disposition of its fleet in accordance with another of its original investment objectives, realizing the residual value of its containers after the expiration of their economic useful lives, estimated to be between 12 to 15 years after placement in leased service.

     The Partnership has commenced its 14th year of operations, and is in its liquidation phase wherein CCC is focusing its attention on the retirement of the remaining equipment in the Partnership’s container fleet. At June 30, 2006, approximately 30% of the original equipment remained in the Partnership’s fleet. The Partnership has been actively disposing of its fleet, with cash proceeds from equipment disposals, in addition to cash from operations, providing the cash flow for distributions to its limited partners. CCC will take several factors into consideration when examining options for the timing of the disposal of the containers. These factors include the impact of a diminishing fleet size and current market conditions on the level of gross lease revenue, and fixed operating costs relative to this revenue. Parallel to these considerations will be a projected increase in expenses for devoting significant resources to the additional reporting and compliance requirements of Section 404 of the Sarbanes Oxley Act of 2002, which addresses a range of corporate governance, disclosure, and accounting issues. These costs may include increased accounting and administrative expenses for additional staffing and outside professional services by accountants and consultants. These additional costs, depending on their materiality, may reduce the Partnership’s results from operations and therefore negatively affect future distributions to the Limited Partners. Upon the liquidation of CCC’s interest in the Partnership, CCC shall contribute to the Partnership, if necessary, an amount equal to the lesser of the deficit balance in its capital account at the time of such liquidation, or 1.01% of the excess of the Limited Partners’ capital contribution to the Partnership over the capital contributions previously made to the Partnership by CCC, after giving effect to the allocation of income or loss arising from the liquidation of the Partnership’s assets.

     Distributions are paid monthly, based primarily on each quarter’s cash flow from operations. Monthly distributions are also affected by periodic increases or decreases to working capital reserves, as deemed appropriate by CCC, the general partner. Cash distributions from operations are allocated 5% to CCC and 95% to the limited partners. Distribution of sales proceeds are allocated 1% to CCC and 99% to the limited partners. This sharing arrangement will remain in place until the limited partners have received aggregate distributions in an amount equal to their capital contributions, plus a 10% cumulative, compounded (daily) annual return on their adjusted capital contributions. Thereafter, all distributions will be allocated 15% to CCC and 85% to the limited partners, pursuant to Section 6.1(b) of the partnership agreement. Cash distributions from operations in excess of 5% of distributable cash will be considered an incentive fee and compensation to CCC.

     At June 30, 2006, the Partnership had $1,231,941 in cash and cash equivalents, a decrease of $246,888 from the cash balances at December 31, 2005. The Partnership invests its working capital, as well as cash flows from operations and the sale of containers that have not yet been distributed to CCC or its limited partners, in money market funds. At June 30, 2006, the Partnership had an additional $30,000 as part of its working capital for estimated expenses related to the ultimate sale of its remaining containers, final liquidation of its remaining assets and subsequent dissolution.

     Cash from Operating Activities: Net cash provided by operating activities, primarily generated from the billing and collection of net lease revenue, was $636,864 during the six months ended June 30, 2006, compared to $822,292 for the same six-month period in 2005.

     Cash from Investing Activities: Net cash provided by investing activities was $1,000,843 during the six months ended June 30, 2006, compared to $1,223,947 in the corresponding period of 2005. These amounts represent sales proceeds generated from the sale of container equipment and proceeds collected from the sales-type lease receivables.

16

     Cash from Financing Activities: Net cash used in financing activities was $1,884,595 during the six months ended June 30, 2006 compared to $2,478,129 during the six months ended June 30, 2005. These amounts represent distributions to the Partnership’s general and limited partners. The Partnership’s continuing container disposals should produce lower operating results, and consequently, lower distributions to its partners in subsequent periods.

Critical Accounting Policies

     The Partnership’s accounting policies are fundamental to understanding management’s discussion and analysis of results of operations and financial condition. The Partnership has identified three policies as being significant because they require the Partnership to make subjective and/or complex judgments about matters that are inherently uncertain. These policies include the following:

• Container equipment – depreciable lives

• Container equipment – valuation

• Allowance for doubtful accounts

     The Partnership, in consultation with its audit committee, has reviewed and approved these significant accounting policies which are further described in the Partnership’s 2005 Annual Report on Form 10-K.

Inflation

     The Partnership believes inflation has not had a material adverse effect on the results of its operations.

17

Item 3. Quantitative and Qualitative Disclosures about Market Risk

     Exchange rate risk: Substantially all of the Partnership’s revenues are billed and paid in US dollars and a significant portion of costs are billed and paid in US dollars. The Leasing Company believes that the proportion of US dollar revenues may decrease in future years, reflecting a more diversified customer base and lease portfolio. Of the non-US dollar direct operating expenses, the majority is individually small, unpredictable and incurred in various denominations. Thus, the Leasing Company determined such amounts are not suitable for cost effective hedging. As exchange rates are outside of the control of the Partnership and Leasing Company, there can be no assurance that such fluctuations will not adversely affect the Partnership’s results of operations and financial condition.

Item 4. Controls and Procedures

     The principal executive and principal financial officers of CCC have evaluated the disclosure controls and procedures of the Partnership as of the end of the period covered by this quarterly report. As used herein, the term “disclosure controls and procedures” has the meaning given to the term by Rule 13a-15 under the Securities Exchange Act of 1934, as amended (“Exchange Act”), and includes the controls and other procedures of the Partnership that are designed to ensure that information required to be disclosed by the Partnership in the reports that it files with the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Based upon their evaluation, the principal executive and principal financial officers of CCC have concluded that the Partnership’s disclosure controls and procedures were effective such that the information required to be disclosed by the Partnership in this quarterly report is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms applicable to the preparation of this quarterly report and is accumulated and communicated to CCC’s management, including CCC’s principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures.

     There has been no change in the Partnership’s internal control over financial reporting (as defined in Rule 13a-15(f)) that occurred during the fiscal quarter ended June 30, 2006, that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.
