EXPLANATORY NOTE

This report combines the annual reports on Form 10-K for the year ended December 31, 2011 of Prologis, Inc. and Prologis, L.P. Unless stated otherwise or the context otherwise requires, references to “Prologis, Inc.” or the “REIT”, mean Prologis, Inc., and its consolidated subsidiaries; and references to “Prologis, L.P.” or the “Operating Partnership” mean Prologis, L.P., and its consolidated subsidiaries. The terms “the Company”, “Prologis”, “we”, “our” or “us” means the REIT and the Operating Partnership collectively.

Prologis, Inc. is a real estate investment trust and the general partner of the Operating Partnership. As of December 31, 2011, the REIT owned an approximate 99.55% common general partnership interest in the Operating Partnership and 100% of the preferred units in the Operating Partnership. The remaining approximate 0.45% common limited partnership interests are owned by non-affiliated investors and certain current and former directors and officers of the REIT. As the sole general partner of the Operating Partnership, the REIT has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership.

We operate the REIT and the Operating Partnership as one enterprise. The management of the REIT consists of the same members as the management of the Operating Partnership. These members are officers of the REIT and employees of the Operating Partnership or one of its direct or indirect subsidiaries. As general partner with control of the Operating Partnership, the REIT consolidates the Operating Partnership for financial reporting purposes, and the REIT does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the REIT and the Operating Partnership are the same on their respective financial statements.

We believe combining the annual reports on Form 10-K of the REIT and the Operating Partnership into this single report results in the following benefits:

We believe it is important to understand the few differences between the REIT and the Operating Partnership in the context of how we operate as an interrelated consolidated company. The REIT’s only material asset is its ownership of partnership interests in the Operating Partnership. As a result, the REIT does not conduct business itself, other than acting as the sole general partner of the Operating Partnership and issuing public equity from time to time. The REIT itself does not issue any indebtedness, but guarantees the unsecured debt of the Operating Partnership. The Operating Partnership holds substantially all the assets of the business, directly or indirectly, and holds the ownership interests in the Company’s investment in certain investees. The Operating Partnership conducts the operations of the business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by the REIT, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates the capital required by the business through the Operating Partnership’s operations, its incurrence of indebtedness and the issuance of partnership units to third parties.

Noncontrolling interests, stockholders’ equity and partners’ capital are the main areas of difference between the consolidated financial statements of the REIT and those of the Operating Partnership. The noncontrolling interests in the Operating Partnership’s financial statements include the interests in consolidated investees not owned by the Operating Partnership. The noncontrolling interests in the REIT’s financial statements include the same noncontrolling interests at the Operating Partnership level, as well as the common limited partnership interests in the Operating Partnership, which are accounted for as partners’ capital by the Operating Partnership.

In order to highlight the differences between the REIT and the Operating Partnership, there are separate sections in this report, as applicable, that separately discuss the REIT and the Operating Partnership including separate financial statements, controls and procedures sections, and separate Exhibit 31 and 32 certifications. In the sections that combine disclosure of the REIT and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of Prologis.

PART I

ITEM 1. Business

The Company

We are the leading global owner, operator and developer of industrial real estate, focused on markets tied to global trade across the Americas, Europe and Asia. As of December 31, 2011, we owned, or had investments in, on a consolidated basis or through unconsolidated investees, properties and development projects totaling approximately 600 million square feet (55.7 million square meters) in 22 countries. These properties are leased to approximately 4,500 customers, including third-party logistics providers, manufacturers, retailers, transportation companies and other enterprises.

Of the approximately 600 million square feet of our owned and managed portfolio as of December 31, 2011:

Prologis, Inc. (the “REIT”) is a self-administered and self-managed real estate investment trust. The REIT is the sole general partner of Prologis, L.P. (the “Operating Partnership”). We operate the REIT and the Operating Partnership as one enterprise. The management of the REIT consists of the same members as the management of the Operating Partnership. These members are officers of the REIT and employees of the Operating Partnership. As general partner with control of the Operating Partnership, the REIT consolidates the Operating Partnership for financial reporting purposes, and the REIT does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the REIT and the Operating Partnership are the same on their respective financial statements and we refer to the REIT and the Operating Partnership collectively throughout this document as “the Company”, “Prologis”, “we”, “our” or “us”. The REIT commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), and believes the current organization and method of operation will enable the REIT to maintain its status as a REIT. The Operating Partnership was also formed in 1997.

We have investments in entities through a variety of ventures. We co-invest in entities that own multiple properties with private capital investors and provide asset and property management services to these entities. We refer to these entities as co-investment ventures. Our ownership interest in these entities generally ranges from 10-50%. We also have investments in joint ventures, generally with one partner and that we do not manage. We refer to our investments in the entities accounted for on the equity method, both unconsolidated co-investment ventures and joint ventures as unconsolidated investees.

Our global headquarters are located at Pier 1, Bay 1, San Francisco, California 94111 and our global operational headquarters are located at 4545 Airport Way, Denver, Colorado 80239. Our other principal office locations are in Amsterdam, the Grand Duchy of Luxembourg, Mexico City, Shanghai, Singapore and Tokyo.

Merger of AMB and ProLogis and Acquisition of PEPR

On June 3, 2011, AMB Property Corporation (“AMB”) completed the merger with ProLogis, a Maryland REIT (“ProLogis”) in which ProLogis shareholders received 0.4464 of a share of common stock of AMB for each outstanding common share of beneficial interest in ProLogis (the “Merger). Following the Merger, AMB changed its name to Prologis, Inc. In the Merger, AMB was the legal acquirer and ProLogis was the accounting acquirer. In May 2011, we also acquired a controlling interest in and began consolidating ProLogis European Properties (“PEPR”) (the “PEPR Acquisition”).

We have recorded the purchase price allocations for both the Merger ($5.9 billion) and PEPR Acquisition ($1.6 billion) in our December 31, 2011 Consolidated Balance Sheet. Our results for 2011 reflect approximately seven months of the impact of the Merger and the PEPR Acquisition. Therefore, period to period comparisons may not be meaningful. See Note 3 to the Consolidated Financial Statements in Item 8 for more information relating to both the Merger and PEPR Acquisition.

Investment Strategy

We believe that gross domestic product (“GDP”) growth and growth in global trade are important drivers of demand for our product. Trade and GDP are correlated as higher levels of investment, production and consumption within a globalized economy are consistent with increased levels of imports and exports. As the world produces and consumes more, we believe that the volume of global trade will continue to increase at a rate in excess of growth in global GDP. Significant supply chain reconfiguration, obsolescence and customers’ preference to lease, rather than own, facilities also drive demand for quality distribution space.

Our investment strategy focuses on providing distribution and logistics space to customers whose businesses are tied to global trade and depend on the efficient movement of goods through the global supply chain to support global trade. We have a deep global presence with assets under management of $43.8 billion spanning 22 countries on four continents. Our properties are primarily located in two main market categories, global markets and regional markets. Global markets comprise approximately 30 of the largest markets tied to global trade. These markets feature large population centers with high per-capita consumption rates and are located near major airports, seaports and ground transportation systems. Similar to global markets, regional markets benefit from large population centers but typically are not as tied to the global supply chain and are often less supply constrained. As of December 31, 2011, global and regional markets represented approximately 83% and 12%, respectively of our overall owned and managed platform (based on our share of net operating income of the properties). Approximately 5% of our total portfolio falls in markets that we do not classify as global or regional markets. Our investment strategy would be to exit these other markets over time. Our portfolio allows us to have local market knowledge, construction expertise and a commitment to sustainable design. We are supported by a broad and diverse customer base, comprising relationships with multinational corporations that result in repeatable business.

Business Strategy

Our business strategy focuses on three principal lines of business within two business segments, as follows:

Real Estate Operations Segment

Rental Operations - This represents the primary source of our core revenue, earnings and funds from operations (or FFO as defined in “Item 7. Management’s Discussion and Analysis of Financial Condition”). We collect rent from our customers under operating leases, including reimbursements for the vast majority of our operating costs. We seek to generate long-term internal growth in rents by maintaining a high occupancy rate at our properties, by controlling expenses and through contractual rent increases on existing space and renewals on rollover space, thus capitalizing on the economies of scale inherent in owning, operating and growing a large global portfolio. Our rental income is diversified due to both our global presence and our broad customer base. We expect to increase overall rental income primarily through the leasing of space currently available in our properties. We believe that our regular maintenance programs, capital expenditure programs, energy management and sustainability programs create cost efficencies that provide a benefit to our customers as well as the Company.

Capital Deployment Activities - Our development and re-development activities support our rental operations and are therefore included with that line of business for segment reporting. We develop and re-develop industrial properties primarily in global and regional markets to meet our customers’ needs. Within this line of business, we provide additional value creation by utilizing: (i) the land that we currently own in global and regional markets; (ii) the development expertise of our local personnel; (iii) our global customer relationships; and (iv) the demand for high quality distribution facilities in key markets. We seek to increase our rental income and the net asset value of the Company, through the leasing of newly developed space, as well as through the acquisition of new properties. Depending on several factors, we may develop properties directly or in co-investment ventures for long-term hold, for contribution into one of our co-investment ventures, or for sale to third parties. Properties that we choose to contribute or sell may result in the recognition of gains or losses. Generally, in the U.S., Europe and Japan we are developing directly while in emerging markets such as Brazil, China and Mexico we are developing with our private capital partners in a variety of co-investment ventures.

Private Capital Segment - We co-invest in properties with private capital investors through a variety of co-investment ventures. We have a direct and long-standing relationship with a significant number of institutional investors. We tailor industrial portfolios to investors’ specific

Table of Contents

needs and deploy capital in both close-ended and open-ended structures, while providing complete portfolio management and financial reporting services. We generally own 10-50% in the ventures. We believe our co-investment in each of our ventures provides a strong alignment of interests with our co-investment partners’ interests. We generate revenues from our unconsolidated co-investment ventures by providing asset management and property management services. We may also earn revenues through additional services provided such as leasing, acquisition, construction, development, disposition, legal and tax services. Depending on the structure of the venture and the returns provided to our partners, we may also earn revenues through incentive returns or promotes. We believe our co-investment program with private capital investors will continue to serve as a source of capital for new investments and provide revenues for our stockholders, as well as mitigate risk associated with our foreign currency exposure. We expect to grow this business with the formation of new ventures and by raising additional third-party capital in our existing ventures.

Our Operating Segments

As discussed above, our current business strategy includes two operating segments: Real Estate Operations, which includes our Capital Deployment activities, and Private Capital. Our Real Estate Operations segment represents the long-term ownership of industrial operating properties, including development activities. Our Private Capital segment represents the long-term management of co-investment ventures and the properties they own. Please see “Item 1A Risk Factors”, our property information and market presence as presented in “Item 2. Properties”, a discussion of our segment results in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our segment footnote – Note22 to our Consolidated Financial Statements in Item 8 for more information with regard to the investments and results of operations of our segments.

Competition

The existence of competitively priced distribution space available in any market could have a material impact on our ability to rent space and on the rents that we can charge. To the extent we wish to acquire land for future development of properties in our Real Estate Operations segment or dispose of land, we may compete with local, regional, and national developers. We also face competition from investment managers for institutional capital.

We believe we have competitive advantages due to (i) our ability to respond quickly to customers’ needs for high-quality distribution space in key global distribution markets; (ii) our established relationships with key customers served by our local personnel; (iii) our ability to leverage our organizational structure to provide a single point of contact for our global customers through our Global Customer Solutions team; (iv) our property management and leasing expertise; (v) our relationships and proven track record with current and prospective investors in our private capital business; (vi) our global experience in the development and management of industrial properties; (vii) the strategic locations of our land that we expect to develop; and (viii) our personnel who are experienced in the land entitlement process.

Customers

We have developed a customer base that is diverse in terms of industry concentration and represents a broad spectrum of international, national, regional and local distribution space users. At December 31, 2011, in our Real Estate Operations segment, we had 3,163 customers occupying 266.0 million square feet of distribution space. In the unconsolidated properties we manage, we had 2,476 customers occupying 249.3 million square feet of distribution space. In our Real Estate Operations segment, our largest customer and 25 largest customers accounted for 0.6% and 7.2%, respectively, of our annualized base rent at December 31, 2011.

Within our Global Customer Solutions team, we develop long-term relationships with our customers and understand their business and needs, serving as their strategic partner for real estate on a global basis. Keeping in close contact with customers and focusing on exceptional customer service sets us apart from other real estate providers as much more than a landlord. We believe that what we offer in terms of scope, scale and quality of assets is unique. Our in-depth knowledge of our markets helps us stay ahead of trends and create forward-thinking solutions for their distribution networks. This depth of customer knowledge results in greater retention and expanded service, which garners additional business from the same customer across multiple geographies. Approximately 50.0 % of our annual base rent is derived from customers who lease from us in more than one location and more than one country.

In our Private Capital segment, we consider our private capital investors to be our customers. As of December 31, 2011, we partnered with 117 investors, several of which invest in multiple funds.

Employees

We employ 1,457 persons in our entire organization. Our employees work in four countries in the Americas (925 persons), in 15 countries in Europe (345 persons) and in three countries in Asia (187 persons). Of the total, we have assigned 862 employees to our Real Estate Operations segment and 67 employees to our Private Capital segment. We have 528 employees who work in corporate and support positions who are not assigned to a segment who may assist with segment activities. We believe our relationships with our employees are good. Our employees are not organized under collective bargaining agreements, although some of our employees in Europe are represented by statutory Works Councils and benefit from applicable labor agreements.

Management’s Overview

At the time of the Merger, we established key strategic priorities to guide our path over the next two years. These priorities are:

Table of Contents

Align our Portfolio with our Investment Strategy

Subsequent to the Merger, we performed a comprehensive review of our owned and managed portfolio, and categorized the portfolio into three main segments – global, regional and other markets. Global markets represent approximately 83% of our overall owned and managed platform (based on our share of net operating income of the properties). Regional markets represent 12% of our total owned and managed platform. We intend to hold only the highest quality class-A product in our regional markets. We also own a small number of assets in other markets, which account for 5% of our owned and managed platform and that we plan to exit from in an orderly fashion in the next few years. By segmenting our markets in this manner, we were able to construct a strategy that includes culling the portfolio for buildings and potentially submarkets that are no longer a strategic fit for the company. We expect to use the proceeds from dispositions to pay down debt and to recycle capital into new development projects or strategic acquisitions.

Strengthen our Financial Position

We intend to further strengthen our financial position by lowering our financial risk and currency exposure and building one of the strongest balance sheets in the REIT industry. We expect to lower our financial risk by reducing leverage and maintaining staggered debt maturities, which will provide us with more financial flexibility and allow continued access to debt capital markets. This financial flexibility will position us to capitalize on market opportunities across the entire business cycle as they become available. We expect to lower our currency exposure by owning assets outside the U.S. primarily in co-investment ventures in which we maintain an ownership interest and provide services generating private capital revenue. We will accomplish this through contributions and sales to our existing and newly formed co-investment ventures. In addition, we expect that new development projects, particularly in emerging markets such as Brazil, China and Mexico, will be done in conjunction with our private capital partners. We will also reduce our exposure to foreign currency exchange fluctuations by borrowing in local currencies when appropriate.

Streamline Private Capital Business

We are rationalizing our private capital business in conjunction with our private capital investors. Some of our co-investment ventures have fee structures that do not adequately compensate us for the services we provide. Therefore, we may terminate or restructure certain of these co-investment ventures. In other cases, we may combine some co-investment ventures to gain operational efficiencies. In every case, however, we will work very closely with our partners and venture investors who will be active participants in these decisions. We plan to grow our private capital business with the deployment of the private capital commitments we have already raised, formation of new co-investment ventures and raising incremental capital for our existing co-investment ventures.

Improve the Utilization of Our Low Yielding Assets

We plan to increase the value of our low yielding assets by stabilizing our operating portfolio to its historical average of 95% leased, completing the build-out and lease-up of our development projects as well as monetizing our land through development or sale to third parties.

Build the most effective and efficient organization in the REIT industry and become the employer of choice among top professionals interested in real estate as a career

We have identified more than $115 million of Merger cost synergies on an annualized basis, as compared to the combined expenses of AMB and ProLogis on a pre-Merger basis. These synergies include gross general and administrative savings, reduced global line of credit facility fees and lower amortization of non real estate assets. We believe we have realized approximately 90% of these synergies already and expect to realize the full amount by year - end 2012. In addition, we are in the process of implementing a new enterprise wide system that will include a property management/billing system, a human resources system, a general ledger and accounting system and a data warehouse. In connection with this implementation, we are striving to utilize the most effective global business processes with the enhanced system functionality. We have implemented two new compensation plans that we believe will better align employees’ compensation to our performance. We believe these efforts and others will help us with the attainment of this objective.

See “Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations” for a discussion of our 2011 results and progress attaining the objectives outlined above.

Code of Ethics and Business Conduct

We maintain a Code of Ethics and Business Conduct applicable to our Board and all of our officers and employees, including the principal co-executive officers, the principal financial officer and the principal accounting officer, or persons performing similar functions. A copy of our Code of Ethics and Business Conduct is available on our website, www.prologis.com. In addition to being accessible through our website, copies of our Code of Ethics and Business Conduct can be obtained, free of charge, upon written request to Investor Relations, Pier 1, Bay 1, San Francisco, California 94111. Any amendments to or waivers of our Code of Ethics and Business Conduct that apply to the principal

Table of Contents

executive officers, the principal financial officer, or the principal accounting officer, or persons performing similar functions, and that relate to any matter enumerated in Item 406(b) of Regulation S-K, will be disclosed on our website.

Environmental Matters

We are exposed to various environmental risks that may result in unanticipated losses and affect our operating results and financial condition. Either the previous owners or we subjected a majority of the properties we have acquired, including land, to environmental reviews. While some of these assessments have led to further investigation and sampling, none of the environmental assessments has revealed an environmental liability that we believe would have a material adverse effect on our business, financial condition or results of operations. See Note 21 to our Consolidated Financial Statements in Item 8 and “Item 1A. Risk Factors”.

Insurance Coverage

We carry insurance coverage on our properties. We determine the type of coverage and the policy specifications and limits based on what we deem to be the risks associated with our ownership of properties and our business operations in specific markets. Such coverages include property damage and rental loss insurance resulting from such perils as fire, additional perils as covered under an extended coverage policy, named windstorm, flood, earthquake and terrorism; commercial general liability insurance; and environmental insurance. Insurance is maintained through a combination of commercial insurance, self insurance and through a wholly-owned captive insurance entity. We believe that our insurance coverage contains policy specifications and insured limits that are customary for similar properties, business activities and markets and we believe our properties are adequately insured. However, an uninsured loss could result in loss of capital investment and anticipated revenues and earnings. See further discussion in “Item 1A. Risk Factors”.

ITEM 1A. Risk Factors

Our operations and structure involve various risks that could adversely affect our financial condition, results of operations, distributable cash flow and value of our securities. These risks include, among others:

General

Disruptions in the Global Capital and Credit Markets may adversely affect our operating results and financial condition.

Global market and economic conditions have been challenging with tighter credit conditions and slower growth in most major economies during the last few years. Although signs of recovery may exist, there are continued concerns about the systemic impact of inflation, the availability and cost of credit, a lagging real estate market and geopolitical issues that contribute to increased market volatility and uncertain expectations for the global economy. To the extent there is turmoil in the financial markets, it has the potential to materially affect the value of our properties and investments in our unconsolidated investees, the availability or the terms of financing that we and our unconsolidated investees have or may anticipate utilizing, our ability and that of our unconsolidated investees to make principal and interest payments on, or refinance any outstanding debt when due and may impact the ability of our customers to enter into new leasing transactions or satisfy rental payments under existing leases.

The market volatility over the last several years has made the valuation of our properties and those of our unconsolidated investees more difficult. There may be significant uncertainty in the valuation, or in the stability of the value, of our properties and those of our unconsolidated investees, that could result in a decrease in the value of our properties and those of our unconsolidated investees. As a result, we may not be able to recover the current carrying amount of our investments in real estate properties, including our unconsolidated investees, which may require us to recognize an impairment charge in earnings in addition to the charges we previously recognized.

Any additional, continued or recurring disruptions in the capital and credit markets may adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to our security holders and the market price of our securities.

As a global company, we are subject to social, political and economic risks of doing business in many countries.

We conduct a significant portion of our business and employ a substantial number of people outside of the United States. During 2011, we generated approximately 41.9% or $642 million 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:

Table of Contents

Our global growth (including growth in new regions in the United States) also subjects us to certain risks, including risks associated with funding increasing headcount, integrating new offices, and establishing effective controls and procedures to regulate the operations of new offices and to monitor compliance with regulations such as the Foreign Corrupt Practices Act, the UK Bribery Act and similar laws.

Although we have committed substantial resources to expand our global platform, if we are unable to successfully manage the risks associated with our global business or to adequately manage operational fluctuations, our business, financial condition and 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 currency exchange control regulations, transfer pricing regulations and potentially adverse tax consequences, among other things.

The depreciation in the value of the foreign currency in countries where we have a significant investment may adversely affect our results of operations and financial position.

We have pursued, and intend to continue to pursue, growth opportunities in international markets where the U.S. dollar is not the functional currency. At December 31, 2011, approximately 43.5% or $12.1 billion of our total assets are invested in a currency other than the U.S. dollar, primarily the euro, Japanese yen and British pound sterling. As a result, we are subject to foreign currency risk due to potential fluctuations in exchange rates between foreign currencies and the U.S. dollar. A significant change in the value of the foreign currency of one or more countries where we have a significant investment may have a material adverse effect on our financial position, debt covenant ratios and results of operations. Although we attempt to mitigate adverse effects by borrowing under debt agreements denominated in foreign currencies and, on occasion and when deemed appropriate, using derivative contracts, there can be no assurance that those attempts to mitigate foreign currency risk will be successful.

Real estate investments are not as liquid as certain other types of assets, which may reduce economic returns to investors.

Real estate investments are not as liquid as certain other types of investments and this lack of liquidity may limit our ability to react promptly to changes in economic or other conditions. In addition, significant expenditures associated with real estate investments, such as secured mortgage payments, real estate taxes and maintenance costs, are generally not reduced when circumstances cause a reduction in income from the investments. Like other companies qualifying as REITs under the Internal Revenue Code, we are only able to hold property for sale in the ordinary course of business through taxable REIT subsidiaries in order to not incur punitive taxation on any tax gain from the sale of such property. While we may dispose of certain properties that have been held for investment in order to generate liquidity, if we do not satisfy certain safe harbors or we believe there is too much risk of incurring the punitive tax on any tax gain from the sale, we may not pursue such sales.

In the event that we do not have sufficient cash available to us through our operations or available credit facilities to continue operating our business as usual, we may need to find alternative ways to increase our liquidity. Such alternatives may include, without limitation, divesting ourselves of properties, whether or not they otherwise meet our strategic objectives to keep in the long term, at less than optimal terms, incurring debt, entering into leases with our customers at lower rental rates or less than optimal terms or entering into lease renewals with our existing customers without an increase in rental rates at turnover. There can be no assurance, however, that such alternative ways to increase our liquidity will be available to us. Additionally, taking such measures to increase our liquidity may adversely affect our financial condition, results of operations, cash flow, our ability to make distributions and payments to our security holders and the market price of our securities.

Risks Related to our Business

General economic conditions and other events or occurrences that affect areas in which our properties are geographically concentrated, may impact financial results.

We are exposed to general economic conditions, local, regional, national and international economic conditions and other events and occurrences that affect the markets in which we own properties. Our operating performance is further impacted by the economic conditions of the specific markets in which we have concentrations of properties.

As of December 31, 2011, approximately 23.0% of our consolidated operating properties or $4.9 billion (based on investment before depreciation) are located in California, which represented 18.8% of the aggregate square footage of our operating properties and 20.8% of our annualized base rent. Our revenue from, and the value of, our properties located in California may be affected by local real estate conditions (such as an oversupply of or reduced demand for industrial properties) and the local economic climate. Business layoffs, downsizing, industry

Table of Contents

slowdowns, changing demographics and other factors may adversely impact California’s economic climate. Because of the number of properties we have located in California, a downturn in California’s economy or real estate conditions could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to our security holders and the market price of our securities.

In addition to California, we also have significant holdings (defined as more than 3% of total investment before depreciation) in operating properties in certain global and regional markets located in Chicago, Dallas/Fort Worth, France, Japan, New Jersey/New York City, South Florida and the United Kingdom. Our operating performance could be adversely affected if conditions become less favorable in any of the markets in which we have a concentration of properties. Conditions such as an oversupply of distribution space or a reduction in demand for distribution space, among other factors, may impact operating conditions. Any material oversupply of distribution space or material reduction in demand for distribution space could adversely affect our results of operations, distributable cash flow and the value of our securities.

In addition, our unconsolidated investees have concentrations of properties in the same markets mentioned above, as well as in markets in Central and Eastern Pennsylvania, Germany, Mexico, Poland and Reno and are subject to the economic conditions in those markets.

A number of our properties are located in areas that are known to be subject to earthquake activity. U.S. properties located in active seismic areas include properties in the San Francisco Bay Area, Los Angeles, and Seattle. International properties located in active seismic areas include Japan and Mexico. We generally carry earthquake insurance on our properties located in areas historically subject to seismic activity, subject to coverage limitations and deductibles if we believe it is commercially reasonable. We evaluate our earthquake insurance coverage annually in light of current industry practice through an analysis prepared by outside consultants and in some specific instances have elected to self insure our earthquake exposure based on this analysis. We have elected not to carry earthquake insurance for wholly owned assets in Japan based on this analysis.

Further, a number of our properties are located in areas that are known to be subject to hurricane and/or flood risk. We carry hurricane and flood hazard insurance on all of our properties located in areas historically subject to such activity, subject to coverage limitations and deductibles if we believe it is commercially reasonable. We evaluate our insurance coverage annually in light of current industry practice through an analysis prepared by outside consultants.

Our insurance coverage does not include all potential losses.

We and our unconsolidated investees currently carry insurance coverage including property damage and rental loss insurance resulting from certain perils such as fire and additional perils as covered under an extended coverage policy, namely windstorm, flood, earthquake and terrorism; commercial general liability insurance; and environmental insurance, as appropriate for the markets where each of our properties and business operations are located. The insurance coverage contains policy specifications and insured limits customarily carried for similar properties, business activities and markets. We believe our properties and the properties of our unconsolidated investees are adequately insured. However, there are certain losses, including losses from floods, earthquakes, acts of war, acts of terrorism or riots, that are not generally insured against or that are not generally fully insured against because it is not deemed economically feasible or prudent to do so. If an uninsured loss or a loss in excess of insured limits occurs with respect to one or more of our properties, we could experience a significant loss of capital invested and future revenues in these properties and could potentially remain obligated under any recourse debt associated with the property.

Furthermore, we cannot be sure that our insurance companies will be able to continue to offer products with sufficient coverage at commercially reasonable rates. If we experience a loss that is uninsured or that exceeds insured limits with respect to one or more of our properties or if our insurance companies fail to meet their coverage commitments to us in the event of an insured loss, then we could lose the capital invested in the damaged properties, as well as the anticipated future revenue from those properties and, if there is recourse debt, then we would remain obligated for any mortgage debt or other financial obligations related to the properties. Any such losses or higher insurance costs could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to our security holders and the market price of our securities.

Investments in real estate properties are subject to risks that could adversely affect our business.

Investments in real estate properties are subject to varying degrees of risk. While we seek to minimize these risks through geographic diversification of our portfolio, market research and our property management capabilities, these risks cannot be eliminated. Some of the factors that may affect real estate values include:

Table of Contents

Our investments are concentrated in the industrial distribution sector and our business would be adversely affected by an economic downturn in that sector.

Our investments in real estate assets are primarily concentrated in the industrial distribution sector. This concentration may expose us to the risk of economic downturns in this sector to a greater extent than if our business activities were more diversified.

Our operating results and distributable cash flow will depend on the continued generation of lease revenues from customers and we may be unable to lease vacant space or renew leases or re-lease space on favorable terms as leases expire.

Our operating results and distributable cash flow would be adversely affected if a significant number of our customers were unable to meet their lease obligations. We are also subject to the risk that, upon the expiration of leases for space located in our properties, leases may not be renewed by existing customers, the space may not be re-leased to new customers or the terms of renewal or re-leasing (including the cost of required renovations or concessions to customers) may be less favorable to us than current lease terms. Our competitors may offer space at rental rates below current market rates or below the rental rates we currently charge our customers, we may lose potential customers, and we may be pressured to reduce our rental rates below those we currently charge in order to retain customers when our customers’ leases expire. In the event of default by a significant number of customers, we may experience delays and incur substantial costs in enforcing our rights as landlord, and may be unable to re-lease spaces. A customer may experience a downturn in its business, which may cause the loss of the customer or may weaken its financial condition, resulting in the customer’s failure to make rental payments when due or requiring a restructuring that might reduce cash flow from the lease. In addition, a customer may seek the protection of bankruptcy, insolvency or similar laws, which could result in the rejection and termination of such customer’s lease and thereby cause a reduction in our available cash flow.

If we decide to contribute or sell properties to an unconsolidated investee or third parties to generate proceeds, we may not be successful.

We may contribute or sell properties to certain of our unconsolidated investees or third parties on a case-by-case basis. Our ability to sell properties on advantageous terms is affected by competition from other owners of properties that are trying to dispose of their properties; market conditions, including the capitalization rates applicable to our properties; and other factors beyond our control. If our competitors sell assets similar to assets we intend to divest in the same markets and/or at valuations below our valuations for comparable assets, we may be unable to divest our assets at favorable pricing or on favorable terms or at all. The unconsolidated investee or third parties who might acquire our properties may need to have access to debt and equity capital, in the private and public markets, in order to acquire properties from us. Should they have limited or no access to capital on favorable terms, then dispositions could be delayed. If we are unable to generate proceeds through property sales we may have to delay our deleveraging plans, which may result in adverse effects on our liquidity, distributable cash flow, debt covenant ratios, and the value of our securities.

We may acquire properties, which involves risks that could adversely affect our operating results and the value of our securities.

We may acquire industrial properties. The acquisition of properties involves risks, including the risk that the acquired property will not perform as anticipated and that any actual costs for rehabilitation, repositioning, renovation and improvements identified in the pre-acquisition due diligence process will exceed estimates. When we acquire properties, we may face risks associated with a lack of market knowledge or understanding of the local economy, forging new business relationships in the area and unfamiliarity with local government and permitting procedures. Additionally, there is, and it is expected there will continue to be, significant competition for properties that meet our investment criteria as well as risks associated with obtaining financing for acquisition activities.

Our real estate development strategies may not be successful.

Our real estate development strategy is focused on monetizing land in the future through sales to third parties, development of industrial properties to hold for long-term investment or contribution or sale to an unconsolidated investee, depending on market conditions, our liquidity needs and other factors. We may expand investment in our development, renovation and redevelopment business and we will complete the build-out and leasing of our development platform. We may also develop, renovate and redevelop properties within existing or newly formed development co-investment ventures. The real estate development, renovation and redevelopment business involves significant risks that could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to our security holders and the market price of our securities, which include the following risks:

Table of Contents

We are exposed to various environmental risks that may result in unanticipated losses that could affect our operating results and financial condition.

Under various federal, state and local laws, ordinances and regulations, a current or previous owner, developer or operator of real estate may be liable for the costs of removal or remediation of certain hazardous or toxic substances. The costs of removal or remediation of such substances could be substantial. Such laws often impose liability without regard to whether the owner or operator knew of, or was responsible for, the release or presence of such hazardous substances. In addition, third parties may sue the owner or operator of a site for damages based on personal injury, property damage or other costs, including investigation and clean-up costs, resulting from the environmental contamination.

Environmental laws in some countries, including the United States, also require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, adequately inform or train those who may come into contact with asbestos and undertake special precautions, including removal or other abatement, in the event that asbestos is disturbed during building renovation or demolition. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos. Some of our properties are known to contain asbestos-containing building materials.

In addition, some of our properties are leased or have been leased, in part, to owners and operators of businesses that use, store or otherwise handle petroleum products or other hazardous or toxic substances, creating a potential for the release of such hazardous or toxic substances. Further, certain of our properties are on, adjacent to or near other properties that have contained or currently contain petroleum products or other hazardous or toxic substances, or upon which others have engaged, are engaged or may engage in activities that may release such hazardous or toxic substances. From time to time, we may acquire properties, or interests in properties, with known adverse environmental conditions where we believe that the environmental liabilities associated with these conditions are quantifiable and that the acquisition will yield a superior risk-adjusted return. In connection with certain divested properties, we have agreed to remain responsible for, and to bear the cost of, remediating or monitoring certain environmental conditions on the properties.

We cannot give any assurance that other such conditions do not exist or may not arise in the future. The presence of such substances on our real estate properties could adversely affect our ability to lease, develop or sell such properties or to borrow using such properties as collateral and may have an adverse effect on our distributable cash flow.

We are subject to risks and liabilities in connection with forming co-investment ventures, investing in new or existing co-investment ventures, attracting third party investment and investing in and managing properties through co-investment ventures.

As of December 31, 2011, we have an investment in approximately 277.8 million square feet held through unconsolidated investees. Our organizational documents do not limit the amount of available funds that we may invest in unconsolidated investees, and we may and currently intend to develop and acquire properties through co-investment ventures and investments in other entities when warranted by the circumstances. However, there can be no assurance that we will be able to form new co-investment ventures, attract third party investment or make additional investments in new or existing co-investment ventures, successfully develop or acquire properties through unconsolidated entities, or realize value from such unconsolidated entities. Our inability to do so may have an adverse effect on our growth, our earnings and the market price of our securities.

Our partners in our unconsolidated investments may share certain approval rights over major decisions and some partners may manage the properties in the unconsolidated investees. Our unconsolidated investments involve certain risks, including:

11

Table of Contents

We generally seek to maintain sufficient influence over our unconsolidated investees to permit us to achieve our business objectives; however, we may not be able to do so, and the occurrence of one or more of the events described above could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to our security holders and the market price of our securities.

Contingent or unknown liabilities could adversely affect our financial condition.

We have acquired and may in the future acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based upon ownership of any of these entities or properties, then we might have to pay substantial sums to settle it, which could adversely affect our cash flow. Contingent or unknown liabilities with respect to entities or properties acquired might include:

Risks Related to Financing and Capital

We face risks associated with the use of debt to fund our business activities, including refinancing and interest rate risks, and our operating results and financial condition could be adversely affected if we are unable to make required payments on our debt or are unable to refinance our debt.

We are subject to risks normally associated with debt financing, including the risk that our cash flow will be insufficient to meet required payments of principal and interest. There can be no assurance that we will be able to refinance any maturing indebtedness, that such refinancing would be on terms as favorable as the terms of the maturing indebtedness, or that we will be able to otherwise obtain funds by selling assets or raising equity to make required payments on maturing indebtedness. If we are unable to refinance our indebtedness at maturity or meet our payment obligations, the amount of our distributable cash flow and our financial condition would be adversely affected and, if the maturing debt is secured, the lender may foreclose on the property securing such indebtedness. Our Global Senior Credit Agreement, Yen-based credit agreement and certain other debt bears interest at variable rates. Increases in interest rates would increase our interest expense under these agreements. In addition, our unconsolidated investees may be unable to refinance indebtedness or meet payment obligations, which may impact our distributable cash flow and our financial condition and/or we may be required to recognize impairment charges of our investments.

Covenants in our credit agreements could limit our flexibility and breaches of these covenants could adversely affect our financial condition.

The terms of our various credit agreements, including our Global Senior Credit Agreement and Yen-based credit agreement, the indentures under which our senior notes are issued and other note agreements, require us to comply with a number of customary financial covenants, such as maintaining debt service coverage, leverage ratios, fixed charge ratios and other operating covenants including maintaining insurance coverage. These covenants may limit our flexibility in our operations, and breaches of these covenants could result in defaults under the instruments governing the applicable indebtedness. If we default under the covenant provisions and are unable to cure the default, refinance the indebtedness or meet payment obligations, the amount of our distributable cash flow and our financial condition could be adversely affected.

Adverse changes in our credit ratings could negatively affect our financing activity.

The credit ratings of our senior unsecured notes and preferred stock are based on our operating performance, liquidity and leverage ratios, overall financial position and other factors employed by the credit rating agencies in their rating analyses of us. Our credit ratings can affect

12

Table of Contents

the amount of capital we can access, as well as the terms and pricing of any debt we may incur. There can be no assurance that we will be able to maintain our current credit ratings, and in the event our credit ratings are downgraded, we would likely incur higher borrowing costs and may encounter difficulty in obtaining additional financing. Also, a downgrade in our credit ratings may trigger additional payments or other negative consequences under our current and future credit facilities and debt instruments. Adverse changes in our credit ratings could negatively impact our refinancing and other capital market activities, our ability to manage debt maturities, our future growth, our financial condition, the market price of our securities, and our development and acquisition activity.

We are dependent on external sources of capital.

In order to qualify as a REIT, we are required each year to distribute to our stockholders at least 90% of our REIT taxable income (determined without regard to the dividends-paid deduction and by excluding any net capital gain) and we may be subject to tax to the extent our income is not fully distributed. While historically we have satisfied these distribution requirements by making cash distributions to our stockholders, we may choose to satisfy these requirements by making distributions of cash or other property, including, in limited circumstances, our own stock. For distributions with respect to taxable years ending on or before December 31, 2011, and in some cases declared as late as December 31, 2012, the REIT can satisfy up to 90% of the distribution requirements discussed above through the distribution of shares of our stock if certain conditions are met. Assuming we continue to satisfy these distribution requirements with cash, we may not be able to fund all future capital needs, including acquisition and development activities, from cash retained from operations and may have to rely on third-party sources of capital. Further, in order to maintain our REIT status and not have to pay federal income and excise taxes, we may need to borrow funds on a short-term basis to meet the REIT distribution requirements even if the then-prevailing market conditions are not favorable for these borrowings. These short-term borrowing needs could result from differences in timing between the actual receipt of cash and inclusion of income for federal income tax purposes, or the effect of non-deductible capital expenditures, the creation of reserves or required debt or amortization payments. Our ability to access debt and equity capital on favorable terms or at all is dependent upon a number of factors, including general market conditions, the market’s perception of our growth potential, our current and potential future earnings and cash distributions and the market price of our securities.

Federal Income Tax Risks

Our failure to qualify as a REIT would have serious adverse consequences.

The REIT elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code, commencing with the taxable year ended December 31, 1997. We believe we have operated so as to qualify as a REIT under the Internal Revenue Code and believe that the current organization and method of operation comply with the rules and regulations promulgated under the Internal Revenue Code to enable us to continue to qualify as a REIT. However, it is possible that we are organized or have operated in a manner that would not allow us to qualify as a REIT, or that our future operations could cause us to fail to qualify. Qualification as a REIT requires us to satisfy numerous requirements (some on an annual and others on a quarterly basis) established under highly technical and complex sections of the Internal Revenue Code for which there are only limited judicial and administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. For example, in order to qualify as a REIT, the REIT must derive at least 95% of its gross income in any year from qualifying sources. In addition, we must pay dividends to our stockholders aggregating annually at least 90% of the REIT taxable income (determined without regard to the dividends paid deduction and by excluding capital gains) and must satisfy specified asset tests on a quarterly basis. The provisions of the Internal Revenue Code and applicable Treasury regulations regarding qualification as a REIT are more complicated in our case because we hold assets through the Operating Partnership.

If we fail to qualify as a REIT in any taxable year, we will be required to pay federal income tax (including any applicable alternative minimum tax) on taxable income at regular corporate rates. Unless we are entitled to relief under certain statutory provisions, we would be disqualified from treatment as a REIT for the four taxable years following the year in which we lost the qualification. If we lost our REIT status, our net earnings would be significantly reduced for each of the years involved.

Furthermore, we own a direct or indirect interest in certain subsidiary REITs which elected to be taxed as REITs under Sections 856 through 860 of the Internal Revenue Code. Provided that each subsidiary REIT qualifies as a REIT, our interest in such subsidiary REIT will be treated as a qualifying real estate asset for purposes of the REIT asset tests, and any dividend income or gains derived by us from such subsidiary REIT will generally be treated as income that qualifies for purposes of the REIT gross income tests. To qualify as a REIT, the subsidiary REIT must independently satisfy all of the REIT qualification requirements. If such subsidiary REIT were to fail to qualify as a REIT, and certain relief provisions did not apply, it would be treated as a regular taxable corporation and its income would be subject to United States federal income tax. In addition, a failure of the subsidiary REIT to qualify as a REIT would have an adverse effect on our ability to comply with the REIT income and asset tests, and thus our ability to qualify as a REIT.

Certain property transfers may generate prohibited transaction income, resulting in a penalty tax on gain attributable to the transaction.

From time to time, we may transfer or otherwise dispose of some of our properties, including by contributing properties to our co-investment ventures. Under the Internal Revenue Code, any gain resulting from transfers of properties we hold as inventory or primarily for sale to customers in the ordinary course of business is treated as income from a prohibited transaction subject to a 100% penalty tax. We do not believe that our transfers or disposals of property or our contributions of properties into our co-investment ventures are prohibited transactions. However, whether property is held for investment purposes is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. The Internal Revenue Service may contend that certain transfers or dispositions of properties by us or contributions of properties into our co-investment ventures are prohibited transactions. While we believe that the Internal Revenue Service

13

Table of Contents

would not prevail in any such dispute, if the Internal Revenue Service were to argue successfully that a transfer, disposition, or contribution of property constituted a prohibited transaction, we would be required to pay a 100% penalty tax on any gain allocable to us from the prohibited transaction. In addition, income from a prohibited transaction might adversely affect our ability to satisfy the income tests for qualification as a REIT.

Legislative or regulatory action could adversely affect us.

In recent years, numerous legislative, judicial and administrative changes have been made to the federal income tax taws applicable to investments in REITs and similar entities. Additional changes to tax laws are likely to continue to occur in the future, and may impact our taxation or that of our stockholders.

Risks relating to the Merger

The combined company may be unable to integrate its businesses successfully and realize the anticipated synergies and related benefits of the Merger or do so within the anticipated timeframe.

On June 3, 2011, AMB and ProLogis completed the Merger. The Merger involved a combination of two companies that previously operated as independent public companies, each of which operated its own private capital platform focused on the industrial real estate sector and served as the sponsor or manager of, or in a similar capacity with respect to, numerous private equity investment vehicles.

The combined company is required to devote significant management attention and resources to integrating the business practices and operations of the constituent companies. Potential difficulties the combined company may encounter in the integration process include the following:

For all these reasons, it is possible that the integration process could result in the distraction of our management, the disruption of our ongoing business or the diversion of our resources to the integration process as we attempt to complete the integration process, any of which could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to security holders and the market price of our securities.

Other Risks

Risks Associated with our Dependence on Key Personnel.

We depend on the efforts of our executive officers and other key employees. From time to time, our personnel and their roles may change. In connection with the completion of the Merger, there were changes to our personnel and their roles. While we believe that we have retained our key talent and can find suitable employees to meet our personnel needs, the loss of key personnel, any change in their roles, or the limitation of their availability could adversely affect our financial condition, results of operations, cash flow and ability to make distributions and payments to security holders and the market price of our securities. If we are unable to continue to attract and retain our executive officers, or if compensation costs required to attract and retain key employees become more expensive, our performance and competitive position could be materially adversely affected.

Compliance or failure to comply with the Americans with Disabilities Act and other similar regulations could result in substantial costs.

Under the Americans with Disabilities Act, places of public accommodation must meet certain federal requirements related to access and use by disabled persons. Noncompliance could result in the imposition of fines by the federal government or the award of damages to private litigants. If we are required to make unanticipated expenditures to comply with the Americans with Disabilities Act, including removing access barriers, then our cash flow and the amounts available to make distributions and payments to our security holders may be adversely affected. Our properties are also subject to various federal, state and local regulatory requirements, such as state and local fire and life-safety requirements. We could incur fines or private damage awards if we fail to comply with these requirements. While we believe that our properties are currently in material compliance with these regulatory requirements, the requirements may change or new requirements may be imposed that could require significant unanticipated expenditures by us that will affect our cash flow and results of operations.

We are subject to governmental regulations and actions that affect operating results and financial condition.

Many laws, including tax laws, and governmental regulations apply to us, our unconsolidated investees and our properties. Changes in these laws and governmental regulations, or their interpretation by agencies or the courts, could occur, which might affect our ability to conduct business.

Table of Contents

Our business could be adversely impacted if we have deficiencies in our disclosure controls and procedures or internal control over financial reporting.

The design and effectiveness of our disclosure controls and procedures and internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. While management will continue to review the effectiveness of our disclosure controls and procedures and internal control over financial reporting, there can be no guarantee that our internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Deficiencies, including any material weakness, in our internal control over financial reporting which may occur in the future could result in misstatements of our results of operations, restatements of our financial statements, a decline in the price of our securities, or otherwise materially adversely affect our business, reputation, results of operations, financial condition or liquidity.

We are exposed to the potential impacts of future climate change and climate change related risks.

We consider that we are exposed to potential physical risks from possible future changes in climate. Our distribution facilities may be exposed to rare catastrophic weather events, such as severe storms and/or floods. If the frequency of extreme weather events increases due to climate change, our exposure to these events could increase.

We do not currently consider ourselves to be exposed to regulatory risks related to climate change, as our operations do not emit a significant amount of greenhouse gases. However, we may be adversely impacted as a real estate developer in the future by potential impacts to the supply chain and/or stricter energy efficiency standards for buildings.

ITEM 1B. Unresolved Staff Comments

None.

ITEM 2. Properties

We are invested in real estate properties that are primarily generic industrial properties. In Japan, our industrial properties are generally multi-level centers, which is common in Japan due to the high cost and limited availability of land. Our properties are typically used for distribution, storage, packaging, assembly and light manufacturing of consumer and industrial products. Based on the square footage of the operating properties included in our Real Estate Operations segment at December 31, 2011 (and discussed below), our properties are 100% industrial properties; including 92.5% used for bulk distribution, 4.4% used for light manufacturing and assembly, 1.3% used for flex industrial, 1.0% used for on-tarmac and 0.8% used for other purposes.

Geographic Distribution

Our investment strategy focuses on providing distribution and logistics space to customers whose businesses are tied to global trade and depend on the efficient movement of goods through the global supply chain. Our properties are primarily located in two main market types, global markets and regional markets. Global markets account for 85.4% of our consolidated operating properties (based on investment balance) and comprise approximately 30 of the largest and most liquid markets tied to global trade. These markets feature large population centers with high per-capita consumption rates and close proximity to airports, seaports and ground transportation systems. Regional markets account for 10.6% of our consolidated operating properties. Similar to global markets, regional markets benefit from large population centers but typically are not as tied to the global supply chain and are often less supply constrained.

Table of Contents

The information in the following tables is as of December 31, 2011 for our consolidated operating properties, properties in our development portfolio and land, including 375 buildings owned by entities we consolidate but of which we own less than 100%. All of these assets are included in our Real Estate Operations segment. This includes our portfolio of operating properties we developed or are currently developing. No individual property or group of properties operating as a single business unit amounted to 10% or more of our consolidated total assets at December 31, 2011 or generated income equal to 10% or more of our consolidated gross revenues for the year ended December 31, 2011. These tables do not include properties that are owned by unconsolidated investees.
