Our Company

We are one of the world’s largest commercial real estate services firms in terms of revenue, offering a full range of services to commercial real estate occupiers, owners, lenders and investors. On July 23, 2003, we completed our acquisition of Insignia, another leading U.S. and international provider of commercial real estate services. Through our acquisition of Insignia, we expect to solidify our position as a market leader in the commercial real estate services industry. In 2002, on a pro forma basis after giving effect to the Insignia acquisition and related transactions, we and Insignia provided commercial real estate services through a combined total of 250 offices in 47 countries. We provide our services under the CB Richard Ellis brand name on a local, national and international basis. During 2002, on a pro forma basis giving effect to the Insignia acquisition and related transactions, we and Insignia advised on approximately 29,050 commercial lease transactions involving aggregate rents of approximately $33.0 billion and approximately 6,160 commercial sales transactions with an aggregate value of approximately $49.0 billion. Also during 2002, on a pro forma basis giving effect to the Insignia acquisition and related transactions, we and Insignia managed approximately 668.5 million square feet of property, provided investment management services for approximately $12.9 billion in assets, originated approximately $9.0 billion in loans, serviced approximately $58.9 billion in loans through a joint venture, engaged in approximately 40,800 valuation, appraisal and advisory assignments and serviced over 1,400 clients with proprietary research.

We report our commercial real estate operations through three geographically-organized segments: (1) Americas, (2) Europe, the Middle East and Africa, or “EMEA,” and (3) Asia Pacific. The Americas consists of operations in the United States, Canada, Mexico and South America. EMEA mainly consists of operations in Europe, and Asia Pacific consists of operations in Asia, Australia and New Zealand. We have worldwide capabilities to assist buyers in the purchase and sellers in the disposition of commercial property, to assist tenants in finding available space and owners in finding qualified tenants, to provide valuations and appraisals for real estate property, to assist in the arrangement of financing for commercial real estate, to provide commercial loan servicing, to provide research and consulting services, to help institutional investors manage commercial real estate portfolios, to provide property and facilities management services and to serve as the outsource service provider to corporations seeking to be relieved of the responsibility for managing their real estate operations.

Competitive Strengths

The market for our commercial real estate business is both highly fragmented and competitive. Thousands of local commercial real estate brokerage firms and hundreds of regional commercial real estate brokerage firms have offices throughout the world. Most of our competitors in the brokerage and asset services lines of business are local or regional firms that are substantially smaller than we are on an overall basis, but in some cases may be larger locally. In addition, there are several national and, in some cases, international real estate brokerage firms with whom we compete. We believe we have a variety of competitive advantages that have helped to establish our strong, global leadership position within the commercial real estate services industry. These advantages include the following:

Our Strategy

Our goal is to be the world’s leading commercial real estate services firm offering unparalleled breadth and quality of services across the globe. To achieve this goal, we intend to:

Summary of the Insignia Acquisition and Related Transactions

On July 23, 2003, we completed our acquisition of Insignia. We believe that the Insignia acquisition significantly increases our scale, business line and regional diversity, as well as strengthens our leadership position in the commercial real estate services industry worldwide. In addition, we believe that the Insignia acquisition provides significant cost-saving opportunities for us. See “Risk Factors—Risks Relating to Our Business—We cannot assure you as to when or if we will be able to achieve all of our expected cost savings in connection with the Insignia acquisition.”

To partially finance the Insignia acquisition, certain of CBRE Holding’s existing stockholders, including affiliates of Blum Capital Partners, L.P., made an aggregate cash contribution of $120.0 million to CBRE

For additional information regarding the terms of the new amended and restated credit agreement, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” and “Description of Other Indebtedness—Our Senior Secured Credit Facilities.” The new amended and restated credit agreement is filed with the Securities and Exchange Commission as an exhibit to the registration statement of which this prospectus forms a part.

On October 27, 2003, CBRE Holding redeemed $20.0 million in aggregate principal amount of its 16% senior notes due 2011. CBRE Holding paid a $1.9 million premium in connection with this redemption.

We are a Delaware corporation, incorporated on March 9, 1989.

RISK FACTORS

You should carefully consider the risks described below and the other information in this prospectus before you decide to participate in the exchange offer. If any of the following risks or uncertainties actually occurs, our business, financial condition and operating results would likely suffer.

Risks Relating to the Exchange Offer

If you choose not to exchange your outstanding notes, the present transfer restrictions will remain in force and the market price of your outstanding notes could decline.

If you do not exchange your outstanding notes for exchange notes under the exchange offer, then you will continue to be subject to the transfer restrictions on the outstanding notes as set forth in the prospectus distributed in connection with the private offering of the outstanding notes. In general, the outstanding notes may not be offered or sold unless they are registered or exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act. You should refer to “Prospectus Summary—Summary of Terms of the Exchange Offer” and “The Exchange Offer” for information about how to tender your outstanding notes.

The tender of outstanding notes under the exchange offer will reduce the principal amount of the outstanding notes outstanding, which may have an adverse effect upon, and increase the volatility of, the market price of the outstanding notes due to a reduction in liquidity.

Risks Relating to Our Business

The success of our business is significantly related to general economic conditions and, accordingly, our business could be harmed in the event of an economic slowdown or recession.

During 2001 and 2002, we continued to be adversely affected by the slowdown in the global economy, which negatively impacted the commercial real estate market. This caused a decline in leasing activities within the United States, which was only partially offset by improved overall revenues in Europe and Asia. During the first three quarters of 2003, lower leasing revenues in the United States were offset by improved revenues from consulting fees and sales of investment properties in the United States and Europe, as well as improved appraisal fees in the United States.

Moreover, in part because of the terrorist attacks on September 11, 2001 and the subsequent outbreak of hostilities, as well as the conflict with Iraq and the risk of conflict with North Korea, the economic climate in the United States and abroad remains uncertain, which may have a further adverse effect on commercial real estate market conditions and, in turn, our operating results.

Periods of economic slowdown or recession in the United States and in other countries, rising interest rates, a declining demand for real estate or the public perception that any of these events may occur, can harm many segments of our business. These economic conditions could result in a general decline in rents, which in turn would reduce revenue from property management fees and brokerage commissions derived from property sales and leases. In addition, these conditions could lead to a decline in sales prices as well as a decline in demand for funds invested in commercial real estate and related assets. A further or continued economic downturn or a significant increase in interest rates also may reduce the amount of loan originations and related servicing by the commercial mortgage banking business. If the brokerage and mortgage banking businesses are negatively impacted, it is likely that the other lines of business would also suffer due to the relationship among the various business lines. Further, as a result of our debt level, the terms of our existing debt instruments and the terms of the debt instruments entered into in connection with the Insignia acquisition and the related transactions, our exposure to adverse general economic conditions is heightened.

Table of Contents

Index to Financial Statements

If the properties that we manage fail to perform, then our financial condition and results of operations could be harmed.

The revenue we generate from our asset services and facilities management lines of business is generally a percentage of aggregate rent collections from properties, although many management agreements provide for a specified minimum management fee. Accordingly, our success partially depends upon the performance of the properties we manage. The performance of these properties will depend upon the following factors, among others, many of which are partially or completely outside of our control:

Our growth has depended significantly upon acquisitions, which may not be available in the future, may result in integration problems and may not perform as we expected.

A significant component of our growth has occurred through acquisitions. Any future growth through acquisitions will be partially dependent upon the continued availability of suitable acquisition candidates at favorable prices and upon advantageous terms and conditions. However, future acquisitions may not be available at advantageous prices or upon favorable terms and conditions. In addition, acquisitions involve risks that the businesses acquired will not perform in accordance with expectations and that business judgments concerning the value, strengths and weaknesses of businesses acquired will prove incorrect.

We have had, and may continue to experience, difficulties in integrating operations and accounting systems acquired from other companies. These difficulties include the diversion of management’s attention from other business concerns and the potential loss of our key employees or those of the acquired operations. We believe that most acquisitions will initially have an adverse impact on operating and net income. We may experience these difficulties in integrating Insignia’s business into our existing business segments. In addition, we generally believe that, as a result of acquisitions, there will be significant costs related to integrating information technology, accounting and management services and rationalizing personnel levels. In connection with the Insignia acquisition, we anticipate recording significant charges during 2003 relating to integration costs. Accordingly, we may not be able to effectively manage acquired businesses and some acquisitions may not have an overall benefit.

We have several different accounting systems as a result of acquisitions we have made. Insignia’s accounting systems are also different from ours. If we are unable to fully integrate the accounting and other systems of the businesses we own, we may not be able to effectively manage our acquired businesses. Moreover, the integration process itself may be disruptive to business as it requires coordination of geographically diverse organizations and implementation of new accounting and information technology systems.

We cannot assure you as to when or if we will be able to achieve all of our expected cost savings in connection with the Insignia acquisition.

Our decision to pursue the Insignia acquisition was based in part on our belief that there are significant cost-saving opportunities for us. After performing a detailed review of Insignia’s and our operations to identify areas of overlap, we have formulated a detailed integration plan in order to achieve these expected cost savings.

16

Table of Contents

Index to Financial Statements

We cannot assure you as to when or if all of the cost savings we expect to achieve in connection with the Insignia acquisition will be realized. A variety of risks could cause us not to achieve the benefits of the expected cost savings, including, among others, the following:

If we fail to realize the expected benefits of the cost savings for these or other reasons, the results of operations of the combined company, as well as our liquidity, could be adversely affected.

We agreed to retain contingent liabilities in connection with Insignia’s sale of substantially all of its real estate investment assets.

Immediately prior to the completion of the Insignia acquisition on July 23, 2003, Insignia completed the sale of substantially all of its real estate investment assets to Island Fund I, LLC (Island Fund). These real estate investment assets were comprised of minority investments in operating real estate assets including office, retail, industrial, apartment and hotel properties, minority investments in office development projects, wholly owned or consolidated investments in real property and investments in real estate-related private equity funds. Under the terms of the purchase agreement that we entered into with Island Fund, we agreed to retain some contingent liabilities related to the real estate investment assets that were sold, and these contingent liabilities could result in material adverse effects on our future financial condition and results of operations. The retained contingent liabilities include the following:

17

Table of Contents

Index to Financial Statements

Although Island Fund has agreed to indemnify us with respect to certain losses related to the real estate investment assets, we may not be able to obtain such indemnification from Island Fund in the future.

In connection with the sale of the real estate investment assets, Island Fund generally agreed to indemnify us against any losses resulting from the ownership, use or operation of the real estate investment assets after the closing of the sale, as well as any losses resulting from any action, or failure to act when action was required, by Island Fund with respect to the real estate investment assets after the closing. In addition, a number of the real estate investment assets that we agreed to sell to Island Fund required the consent of one or more third parties in order to transfer such assets to Island Fund and some of these third party consents were not obtained prior to the closing. As a result, we continue to hold these real estate investment assets pending the receipt of these third party consents. While we continue to hold these assets, we generally have agreed to provide Island Fund with the economic benefits from these assets and Island Fund generally has agreed to indemnify us with respect to any losses incurred in connection with our continuing to hold these assets. With respect to any of the Island Fund indemnification obligations described above, however, there can be no assurance that Island Fund actually will provide, or be able to provide, such indemnification if required to do so at any future date. If Island Fund does not, or is unable to, indemnify us against these potential losses, our future financial condition and results of operations may be adversely impacted.

We have numerous significant competitors, some of which may have greater financial resources than we do.

We compete across a variety of business disciplines within the commercial real estate industry, including investment management, tenant representation, corporate services, construction and development management, property management, agency leasing, valuation and mortgage banking. In general, with respect to each of our business disciplines, we cannot assure you that we will be able to continue to compete effectively, maintain our current fee arrangements or margin levels or not encounter increased competition. Each of the business disciplines in which we compete is highly competitive on an international, national, regional and local level. Although we are one of the largest real estate services firms in the world in terms of revenue, our relative competitive position varies significantly across product and service categories and geographic areas. Depending on the product or service, we face competition from other real estate service providers, institutional lenders, insurance companies, investment banking firms, investment managers and accounting firms. Many of our competitors are local or regional firms, which are substantially smaller than we are; however, they may be substantially larger on a local or regional basis. We are also subject to competition from other large national and multi-national firms.

Our international operations subject us to social, political and economic risks of doing business in foreign countries.

We conduct a substantial portion of our business and employ a substantial number of employees outside of the United States. During the nine-month period ended September 30, 2003, on a pro forma basis giving effect to the Insignia acquisition and related transactions, we generated approximately 28.8% of our revenue from operations outside the United States. Circumstances and developments related to international operations that could negatively affect our business, financial condition or results of operations include, but are not limited to, the following factors:

18

Table of Contents

Index to Financial Statements

We have committed additional resources to expand our worldwide sales and marketing activities, to globalize our service offerings and products in selected markets and to develop local sales and support channels. If we are unable to successfully implement these plans, to maintain adequate long-term strategies that successfully manage the risks associated with our global business or to adequately manage operational fluctuations, our business, financial condition or results of operations could be harmed.

In addition, our international operations and, specifically, the ability of our non-U.S. subsidiaries to dividend or otherwise transfer cash among our subsidiaries, including transfers of cash to pay interest and principal on our debt, may be affected by limitations on imports, currency exchange control regulations, transfer pricing regulations and potentially adverse tax consequences, among other things.

Our revenue and earnings may be adversely affected by foreign currency fluctuations.

Our revenue from non-U.S. operations has been primarily denominated in the local currency where the associated revenue was earned. During the nine-month period ended September 30, 2003, on a pro forma basis giving effect to the Insignia acquisition and related transactions, approximately 28.8% of our business was transacted in currencies of foreign countries, the majority of which included the Euro, the British Pound Sterling, the Hong Kong dollar, the Singapore dollar and the Australian dollar. Thus, we may experience fluctuations in revenues and earnings because of corresponding fluctuations in foreign currency exchange rates.

We have made significant acquisitions of non-U.S. companies and may acquire additional foreign companies in the future. As we increase our foreign operations, fluctuations in the value of the U.S. dollar relative to the other currencies in which we may generate earnings could adversely affect our business, operating results and financial condition. Due to the constantly changing currency exposures to which we will be subject and the volatility of currency exchange rates, we cannot predict the effect of exchange rate fluctuations upon future operating results. In addition, fluctuations in currencies relative to the U.S. dollar may make it more difficult to perform period-to-period comparisons of our reported results of operations.

From time to time, our management uses currency hedging instruments, including foreign currency forward and option contracts and borrows in foreign currencies. Economic risks associated with these hedging instruments include unexpected fluctuations in inflation rates, which impact cash flow relative to paying down debt, and unexpected changes in the underlying net asset position. These hedging activities also may not be effective.

A significant portion of our operations are concentrated in California and New York, and our business could be harmed if the economic downturn continues in the California or New York real estate markets.

For the nine-month period ended September 30, 2003, on a pro forma basis giving effect to the Insignia acquisition and related transactions, a significant amount of our sales and lease revenue, including revenue from investment property sales, was generated from transactions originating in the State of California. In addition, for

19

Table of Contents

Index to Financial Statements

the nine-month period ended September 30, 2003, on the same pro forma basis, a significant amount of our sales and lease revenue, including revenue from investment property sales but excluding revenue from real estate principal investment activities and residential real estate services, was generated from transactions originating in the greater New York metropolitan area. As a result of the geographic concentration in California and New York, a continuation of the economic downturn in the California and New York commercial real estate markets and in the local economies in San Diego, Los Angeles, Orange County or the greater New York metropolitan area could further harm our results of operations.

Our co-investment activities subject us to real estate investment risks which could cause fluctuations in earnings and cash flow.

An important part of the strategy for our investment management business involves investing our capital in certain real estate investments with our clients. As of September 30, 2003, we had committed an additional $21.4 million to fund future co-investments. In addition to required future capital contributions, some of the co-investment entities may request additional capital from us and our subsidiaries holding investments in those assets and the failure to provide these contributions could have adverse consequences to our interests in these investments. Although our and CBRE Holding’s debt instruments contain restrictions that will limit our ability to provide capital to the entities holding direct or indirect interests in co-investments, we may provide this capital in some instances.

Participation in real estate transactions through co-investment activity could increase fluctuations in earnings and cash flow. Other risks associated with these activities include, but are not limited to, the following:

We may incur liabilities related to our subsidiaries being general partners of numerous general and limited partnerships.

We have subsidiaries that are general partners in numerous general and limited partnerships that invest in or manage real estate assets in connection with our co-investments, including several partnerships involved in the acquisition, rehabilitation, subdivision and sale of multi-tenant industrial business parks. Any subsidiary that is a general partner is potentially liable to our partners and for the obligations of the partnership, including those obligations related to environmental contamination of properties owned or managed by the partnership. If our exposure as a general partner is not limited, or if the exposure as a general partner expands in the future, any resulting losses may harm our business, financial condition or results of operations.

Our joint venture activities involve unique risks that are often outside of our control which, if realized, could harm our business.

We have utilized joint ventures for large commercial investments, initiatives in Internet-related technology and local brokerage partnerships. In the future, we may acquire interests in additional limited and general partnerships and other joint ventures formed to own or develop real property or interests in real property. We have acquired and may continue to acquire minority interests in joint ventures. Additionally, we may also acquire interests as a passive investor without rights to actively participate in management of the joint ventures. Investments in joint ventures involve additional risks, including, but not limited to, the following:

20

Table of Contents

If a joint venture participant acts contrary to our interest, it could harm our business, results of operations and financial condition.

Our success depends upon the retention of our senior management, as well as our ability to attract and retain qualified and experienced employees.

Our continued success is highly dependent upon the efforts of our executive officers and other key employees. The members of our senior management that are parties to employment agreements are Raymond E. Wirta, our Chief Executive Officer; Brett White, our President; Kenneth J. Kay, our Chief Financial Officer; Stephen Siegel, our Chairman, Global Brokerage; Mitchell Rudin, our President, U.S. Brokerage Services; and Alan Froggatt, our Chief Executive Officer, EMEA. If any of our key employees leave and we are unable to quickly hire and integrate a qualified replacement, our business, financial condition and results of operations may suffer. In addition, the growth of our business is largely dependent upon our ability to attract and retain qualified personnel in all areas of our business, including brokerage and property management personnel. If we are unable to attract and retain these qualified personnel, our growth may be limited and our business and operating results could suffer.

If we fail to comply with laws and regulations applicable to real estate brokerage and mortgage transactions and other segments of our business, we may incur significant financial penalties.

Due to the broad geographic scope of our operations and the numerous forms of real estate services performed, we are subject to numerous federal, state and local laws and regulations specific to the services performed. For example, the brokerage of real estate sales and leasing transactions requires us to maintain brokerage licenses in each state in which we operate. If we fail to maintain our licenses or conduct brokerage activities without a license, we may be required to pay fines or return commissions received or have licenses suspended. In addition, because the size and scope of real estate sales transactions have increased significantly during the past several years, both the difficulty of ensuring compliance with the numerous state licensing regimes and the possible loss resulting from non-compliance have increased. Furthermore, the laws and regulations applicable to our business, both in the United States and in foreign countries, also may change in ways that materially increase the costs of compliance.

We may have liabilities in connection with real estate brokerage and property management activities.

As a licensed real estate broker, we and our licensed employees are subject to statutory due diligence, disclosure and standard-of-care obligations. Failure to fulfill these obligations could subject us or our employees to litigation from parties who purchased, sold or leased properties we or they brokered or managed. We could become subject to claims by participants in real estate sales claiming that we did not fulfill our statutory obligations as a broker.

In addition, in our property management business, we hire and supervise third-party contractors to provide construction and engineering services for our managed properties. While our role is limited to that of a supervisor, we may be subjected to claims for construction defects or other similar actions. Adverse outcomes of property management litigation could negatively impact our business, financial condition or results of operations.

We are controlled by affiliates of Blum Capital Partners, L.P., whose interests may be different from yours.

We are a wholly owned subsidiary of CBRE Holding. As of October 31, 2003, Blum Strategic Partners, L.P., Blum Strategic Partners II, L.P. and Blum Strategic Partners II GmbH & Co. KG together owned

approximately 67.2% of CBRE Holding’s outstanding Class A and Class B common stock, taken together. In addition, these investment funds, which are affiliates of Blum Capital Partners, L.P., previously entered into a securityholders’ agreement with the other holders of Class B common stock and some of the holders of Class A common stock. The Class A and Class B common stock subject to the voting provisions of the securityholders’ agreement represented as of October 31, 2003 approximately 98.7% of the voting power of CBRE Holding’s outstanding Class A and Class B common stock, taken together. As a result of the percentage of CBRE Holding’s voting power owned by the affiliates of Blum Capital Partners, L.P. and the other parties to the securityholders’ agreement and the rights granted to these investment funds pursuant to the securityholders’ agreement, CBRE Holding is controlled by these affiliates of Blum Capital Partners, L.P., which control has, among other things, the effects indicated below.

We cannot assure you that the interests of the funds affiliated with Blum Capital Partners, L.P. will not conflict with yours. In particular, these funds may cause a change of control at a time when we do not have sufficient funds to repurchase the notes as described under “Description of the Notes—Change of Control.”

Our results of operations vary significantly among quarters, which makes comparison of our quarterly results difficult.

A significant portion of our revenue is seasonal. Historically, this seasonality has caused our revenue, operating income, net income and cash flow from operating activities to be lower in the first two quarters and higher in the third and fourth quarters of each year. The concentration of earnings and cash flow in the fourth quarter is due to an industry-wide focus on completing transactions toward the fiscal year-end, while incurring constant, non-variable expenses throughout the year. This has historically resulted in lower profits or a loss in the first and second quarters, with profits growing (or losses decreasing) in each subsequent quarter.

Risks Relating to Our Substantial Indebtedness

Our substantial leverage and debt service obligations could harm our ability to operate our business, remain in compliance with debt covenants and make payments on our debt, including the notes.

We are highly leveraged and have significant debt service obligations. For the year ended December 31, 2002 and for the nine months ended September 30, 2003, in each case on a pro forma basis after giving effect to the Insignia acquisition and the related transactions, CBRE Holding’s annual interest expense would have been $90.3 million and $71.8 million, respectively. Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on or other amounts due in respect of our indebtedness. In addition, we may incur additional debt from time to time to finance strategic acquisitions, investments, joint ventures or for other purposes, subject to the restrictions contained in the documents governing our indebtedness. If we incur additional debt, the risks associated with our substantial leverage, including our ability to service our debt, would increase.

Our substantial debt could have other important consequences, which include, but are not limited to, the following:

22

Table of Contents

Index to Financial Statements

We cannot be certain that our earnings will be sufficient to allow us to pay principal and interest on our debt, including the notes, and meet our other obligations. If we do not have sufficient earnings, we may be required to refinance all or part of our existing debt, sell assets, borrow more money or sell more securities, none of which we can guarantee we will be able to do.

We will be able to incur more indebtedness, which may intensify the risks associated with our substantial leverage, including our ability to service our indebtedness.

The indenture relating to the notes, the amended and restated credit agreement governing our senior secured credit facilities and the indentures relating to our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior notes due 2011 issued by CBRE Holding permit us, subject to specified conditions, to incur a significant amount of additional indebtedness, including additional indebtedness under our $90.0 million revolving credit facility. If we incur additional debt, the risks associated with our substantial leverage, including our ability to service our debt, would increase.

Servicing our indebtedness requires a significant amount of cash, and our ability to generate cash depends on many factors beyond our control.

We expect to obtain from our operations the cash necessary to make payments on the notes, our senior secured credit facilities, our 11 ¹/4% senior subordinated notes due 2011, the 16% senior notes due 2011 issued by CBRE Holding, and to fund our working capital, strategic acquisitions, investments, joint ventures and other general corporate requirements. Our ability to generate cash from our operations is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. As a result, we cannot assure you that our business will generate sufficient cash flow from operations, that we will realize currently anticipated cost savings, revenue growth and operating improvements on schedule or at all or that future borrowings will be available to us under our revolving credit facility, in each case, in amounts sufficient to enable us to service our debt and to fund our other liquidity needs. If we cannot service our debt, we will have to take actions such as reducing or delaying strategic acquisitions, investments and joint ventures, selling assets, restructuring or refinancing our debt or seeking additional equity capital. We cannot assure you that any of these remedies could, if necessary, be effected on commercially reasonable terms, or at all. In addition, the terms of our and CBRE Holding’s existing or future debt instruments, including our senior secured credit facilities, the indenture for the notes and the indentures for our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior

23

notes due 2011 issued by CBRE Holding, may restrict us from adopting any of these alternatives. Because of these and other factors beyond our control, we may be unable to pay the principal, premium, if any, interest or other amounts on the notes.

Our and CBRE Holding’s debt instruments impose significant operating and financial restrictions on us and CBRE Holding, and in the event of a default, all of our and CBRE Holding’s borrowings would become immediately due and payable.

The indentures governing the notes, our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior notes due 2011 issued by CBRE Holding impose, and the terms of any future debt may impose, operating and other restrictions on CBRE Holding and on us and many of our subsidiaries. These restrictions will affect, and in many respects will limit or prohibit, the ability of CBRE Holding and of us and our restricted subsidiaries to:

In addition, the new amended and restated credit agreement governing our senior secured credit facilities includes other and more restrictive covenants and prohibits us from prepaying most of our other debt while debt under our senior secured credit facilities is outstanding. The new amended and restated credit agreement governing our senior secured credit facilities also requires us to maintain compliance with specified financial ratios. Our ability to comply with these ratios may be affected by events beyond our control.

The restrictions contained in our and CBRE Holding’s debt instruments could:

A breach of any of these restrictive covenants or the inability to comply with the required financial ratios could result in a default under our and CBRE Holding’s debt instruments. If any such default occurs, the lenders under the senior secured credit facilities and the holders of the notes, our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior notes due 2011 issued by CBRE Holding, pursuant to the respective indentures, may elect to declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable. The lenders under our senior secured credit facilities also have the right in these circumstances to terminate any commitments they have to provide further borrowings. If we are unable to repay outstanding borrowings when due, the lenders under the senior secured credit facilities will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash. If the debt under the senior secured credit facilities, the notes, our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior notes due 2011 were to be accelerated, we cannot assure you that our assets would be sufficient to repay in full the notes and our other debt.

We conduct a substantial portion of our operations through our subsidiaries and may be limited in our ability to access funds from these subsidiaries to service our debt, including the notes.

We conduct a substantial portion of our operations through our subsidiaries and depend to a large degree upon dividends and other intercompany transfers of funds from our subsidiaries to meet our debt service and other obligations, including the notes. Our subsidiaries do not have any obligation to pay amounts due on the notes or to make funds available to us for these payments, unless they are guarantors of the notes. In addition, the ability of our subsidiaries to pay dividends and make other payments to us may be restricted by, among other things, applicable corporate and other laws, transfer pricing regulations, limitations on imports, currency exchange control regulations, potentially adverse tax consequences and agreements of our subsidiaries. Although the indentures governing the notes, our 11 ¹/4% senior subordinated notes due 2011 and the 16% senior notes due 2011 issued by CBRE Holding limit the ability of our subsidiaries to enter into consensual restrictions on their ability to pay dividends and make other payments, the limitations are subject to a number of significant qualifications and exceptions. See “Description of the Notes—Certain Covenants—Limitation on Restrictions on Distributions from Restricted Subsidiaries.” If we are unable to access the cash flow of our subsidiaries, we may have difficulty meeting our debt obligations.

If we fail to meet our payment or other obligations under the senior secured credit facilities, the lenders under the senior secured credit facilities could foreclose on, and acquire control of, substantially all of our assets.

In connection with the incurrence of indebtedness under our senior secured credit facilities and the completion of the Insignia acquisition, the lenders under our senior secured credit facilities received a pledge of all of our equity interests and those of CBRE Holding’s significant domestic subsidiaries, including us, CBRE Investors, L.L.C., L.J. Melody & Company, Insignia Financial Group, Inc. and Insignia/ESG, Inc., which was subsequently renamed CB Richard Ellis Real Estate Services, Inc., and 65% of the voting stock of CBRE Holding’s foreign subsidiaries that is held directly by CBRE Holding or its domestic subsidiaries. Additionally, these lenders generally have a lien on substantially all of our accounts receivable, cash, general intangibles, investment property and future acquired material property. As a result of these pledges and liens, if we fail to meet our payment or other obligations under the senior secured credit facilities, the lenders under the senior secured credit facilities would be entitled to foreclose on substantially all of our assets and liquidate these assets. Under those circumstances, we may not have sufficient funds to pay principal, premium, if any, and interest on the notes. As a result, the holders of the notes may lose a portion of, or the entire value of, their investment.

Risks Relating to the Notes

We may not have the ability to raise the funds necessary to finance a change of control offer.

Upon the occurrence of a change of control, we will be required to offer to repurchase all of the notes. We cannot assure you that there will be sufficient funds available for us to make any required repurchases of the notes upon a change of control. In addition, the amended and restated credit agreement governing our senior secured credit facilities will provide that the occurrence of a change of control constitutes a default. Our failure to purchase tendered notes would constitute a default under the indenture governing the notes, which, in turn, would constitute a default under the senior secured credit facilities. See “Description of the Notes—Change of Control.”

A subsidiary guarantee could be voided if it constitutes a fraudulent transfer under U.S. bankruptcy or similar state law, which would prevent the holders of the notes from relying on that subsidiary to satisfy claims.

Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a subsidiary guarantee can be voided, or claims under the subsidiary guarantee may be subordinated to all other debts of that subsidiary guarantor if, among other things, the subsidiary guarantor, at the time it incurred the indebtedness evidenced by its subsidiary guarantee or, in some states, when payments become due under the subsidiary guarantee, received less than reasonably equivalent value or fair consideration for the incurrence of the subsidiary guarantee and:

25

Table of Contents

Index to Financial Statements

A subsidiary guarantee may also be voided, without regard to the above factors, if a court found that the subsidiary guarantor entered into the subsidiary guarantee with the actual intent to hinder, delay or defraud its creditors.

A court would likely find that a subsidiary guarantor did not receive reasonably equivalent value or fair consideration for its subsidiary guarantee if the subsidiary guarantor did not substantially benefit directly or indirectly from the issuance of the notes. If a court were to void a subsidiary guarantee, you would no longer have a claim against the subsidiary guarantor. Sufficient funds to repay the notes may not be available from other sources, including the remaining guarantors, if any. In addition, the court might direct you to repay any amounts that you already received from the subsidiary guarantor.

The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law. Generally, a subsidiary guarantor would be considered insolvent if:

Each subsidiary guarantee will contain a provision intended to limit the subsidiary guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect the subsidiary guarantees from being voided under fraudulent transfer law.

The notes are not guaranteed by all of our subsidiaries.

The notes have not been guaranteed by a number of our subsidiaries. As a result, if we default on our obligations under the notes, you will not have any claims against any of our subsidiaries that do not provide guarantees of the notes. For the nine-month period ended September 30, 2003, on a pro forma basis giving effect to the Insignia acquisition and related transactions, revenues of our non-guarantor subsidiaries constituted approximately 28.8% of our consolidated revenue, operating income of such non-guarantor subsidiaries was $2.6 million and EBITDA of such non-guarantor subsidiaries was $12.6 million. As of September 30, 2003, the total assets of such subsidiaries constituted approximately 20.4% of our consolidated total assets, and the total liabilities (excluding intercompany loans payable) of such subsidiaries were $258.3 million. For additional financial information regarding our guarantor and non-guarantor subsidiaries, see note 17 to CBRE Holding’s September 30, 2003 consolidated financial statements and note 14 to Insignia’s June 30, 2003 consolidated financial statements included elsewhere in this prospectus.

Your ability to recover from our former auditors, Arthur Andersen LLP, for any potential financial misstatements is limited.

On April 23, 2002, at the recommendation of our audit committee, we dismissed Arthur Andersen LLP as our independent public accountants and engaged Deloitte & Touche LLP to serve as our independent public accountants for fiscal year 2002. The audited consolidated financial statements of CBRE Holding as of December 31, 2001 and for the period from February 20, 2001 (inception) through December 31, 2001 and the

audited consolidated financial statements of CB Richard Ellis Services for the period from January 1, 2001 through July 20, 2001 and for the twelve months ended December 31, 2000, which are included in this prospectus, have been audited by Arthur Andersen, our former independent public accountants, as set forth in their report, but Arthur Andersen has not consented to our use of their report in this prospectus.

Arthur Andersen completed its audit of our consolidated financial statements for the year ended December 31, 2001 and issued its report relating to these consolidated financial statements on February 26, 2002. Subsequently, Arthur Andersen was convicted of obstruction of justice for the activities relating to its previous work for another of its audit clients and has ceased to audit publicly-held companies. We are unable to predict the impact of this conviction or whether other adverse actions may be taken by governmental or private entities against Arthur Andersen. If Arthur Andersen has no assets available for creditors, you may not be able to recover against Arthur Andersen for any claims you may have under securities or other laws as a result of Arthur Andersen’s previous role as our independent public accountants and as author of the audit report for some of the audited financial statements included in this prospectus.

We cannot assure you that an active trading market will develop for the exchange notes.

We do not intend to apply for a listing of the exchange notes on a securities exchange. There is currently no established market for the exchange notes and we cannot assure you as to:

Although the initial purchasers of the outstanding notes have advised us that they intend to make a market for the exchange notes, the initial purchasers are not obligated to do so, and may discontinue their market making at any time without notice to the holders of the exchange notes. In addition, market making activity may be limited during the pendency of the exchange offer or the effectiveness of a shelf registration statement. Accordingly, we cannot assure you as to the development or liquidity of any market for the exchange notes. If a market for the exchange notes does develop, prevailing interest rates, the markets for similar securities and other factors could cause the exchange notes to trade at prices lower than their initial market values or reduce the liquidity of the exchange notes.

USE OF PROCEEDS

CB Richard Ellis Services, CBRE Holding and the other guarantors of the outstanding notes will not receive any cash proceeds from the issuance of the exchange notes. In consideration for issuing the exchange notes as contemplated in this prospectus, CB Richard Ellis Services will receive in exchange a like principal amount of outstanding notes, the terms of which are identical in all material respects to the exchange notes. The outstanding notes surrendered in exchange for the exchange notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the exchange notes will not result in any change in our capitalization.

The net proceeds we received from the offering of the outstanding notes, together with cash, borrowings under an amended and restated credit agreement, the proceeds from the sale of real estate investment assets by Insignia to Island Fund and the equity contributions by certain of CBRE Holding’s existing stockholders were used:
