Background and Basis of Presentation	BACKGROUND AND BASIS OF PRESENTATION Description of Business: Prior to June 29, 2012, A&B’s businesses included Matson Navigation Company Inc., a wholly owned subsidiary that provided ocean transportation, truck brokerage and intermodal services. As part of a strategic initiative designed to allow A&B to independently execute its strategies and to best enhance and maximize its growth prospects and shareholder value, A&B made a decision to separate the transportation businesses from the Hawaii real estate and agriculture businesses. In preparation for the separation, A&B modified its legal-entity structure and became a wholly owned subsidiary of a newly created entity, Alexander & Baldwin Holdings, Inc. (“Holdings”). On June 29, 2012, Holdings distributed to its shareholders all of the common stock of A&B stock in a tax-free distribution (the “Separation”). Holders of Holdings common stock continued to own the transportation businesses, but also received one share of A&B common stock for each share of Holdings common stock held at the close of business on June 18, 2012, the record date. Following the Separation, Holdings changed its name to Matson, Inc. On July 2, 2012, A&B began regular trading on the New York Stock Exchange under the ticker symbol “ALEX” as an independent, public company. The financial statements and related financial information pertaining to the period preceding the Separation have been presented on a combined basis and reflect the financial position, results of operations and cash flows of the real estate and agriculture businesses and corporate functions of Alexander & Baldwin, Inc., all of which were under common ownership and common management prior to the Separation. The financial statements and related financial information pertaining to the period subsequent to the Separation have been presented on a consolidated basis. The financial statements for periods prior to the Separation included herein may not necessarily reflect what A&B’s results of operations, financial position and cash flows would have been had A&B been a stand-alone company during the periods presented. A&B is headquartered in Honolulu and, with the acquisition of Grace Pacific ("Grace") on October 1, 2013, operates four segments in three industries—Real Estate, Natural Materials and Construction and Agribusiness. Real Estate: The Real Estate Industry consists of two segments, both of which have operations in Hawaii and on the Mainland. The Real Estate Development and Sales segment generates its revenues through the investment in and development and sale of land and commercial and residential properties. The Real Estate Leasing segment owns, operates, and manages retail, office, and industrial properties in Hawaii and on the Mainland. The Real Estate Leasing segment also leases land in Hawaii. Real estate activities are conducted through A&B Properties, Inc. and various other wholly owned subsidiaries of A&B. Agribusiness: Agribusiness, which contains one segment, produces bulk raw sugar, specialty food grade sugars, and molasses; markets and distributes specialty food-grade sugars; provides general trucking services, mobile equipment maintenance, and repair services in Hawaii; leases agricultural land to third parties; and generates and sells electricity, to the extent not used in the Company’s Agribusiness operations. A&B is the member in Hawaiian Sugar & Transportation Cooperative (“HS&TC”), a cooperative that provides raw sugar marketing and transportation services. Natural Materials and Construction: On October 1, 2013, the Company consummated its acquisition of Grace, a Hawaii-based natural materials and infrastructure construction company. Natural Materials and Construction, which contains one segment and includes the results of Grace from the date of acquisition, mines, processes, and sells basalt aggregate; imports sand and aggregates for sale and use; imports and markets liquid asphalt; manufactures and markets asphaltic concrete; performs asphalt paving as prime contractor and subcontractor; manufactures and supplies precast/prestressed concrete products; and provides various construction- and traffic-control- related products and services. Reclassifications: Certain amounts reflected in the consolidated balance sheets as of December 31, 2012 have been reclassified to conform to the presentation as of December 31, 2013. Intangible assets of $8.3 million, as of December 31, 2012, was reclassified from Other assets to Intangible assets to conform to the presentation used in 2013. Additionally, the Company reclassified certain prior year amounts in the Consolidated Statements of Cash Flows, as discussed below, to improve the transparency of its cash flows. Net cash provided by (used in) operations, net cash used in investing activities and net cash provided by financing activities did not change as a result of the reclassifications. The Company's presentation of 1031 activities in the consolidated statements of cash flows was previously treated as a non-cash investing activity, but are now reflected as additional items within cash flows from investing activities. Rounding: Amounts in the consolidated financial statement and Notes are rounded to the nearest tenth of a million, but per-share calculations were determined based on amounts before rounding. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may be slightly different.

BACKGROUND AND BASIS OF PRESENTATION

Description of Business: Prior to June 29, 2012, A&B’s businesses included Matson Navigation Company Inc., a wholly owned subsidiary that provided ocean transportation, truck brokerage and intermodal services. As part of a strategic initiative designed to allow A&B to independently execute its strategies and to best enhance and maximize its growth prospects and shareholder value, A&B made a decision to separate the transportation businesses from the Hawaii real estate and agriculture businesses. In preparation for the separation, A&B modified its legal-entity structure and became a wholly owned subsidiary of a newly created entity, Alexander & Baldwin Holdings, Inc. (“Holdings”). On June 29, 2012, Holdings distributed to its shareholders all of the common stock of A&B stock in a tax-free distribution (the “Separation”). Holders of Holdings common stock continued to own the transportation businesses, but also received one share of A&B common stock for each share of Holdings common stock held at the close of business on June 18, 2012, the record date. Following the Separation, Holdings changed its name to Matson, Inc. On July 2, 2012, A&B began regular trading on the New York Stock Exchange under the ticker symbol “ALEX” as an independent, public company.

The financial statements and related financial information pertaining to the period preceding the Separation have been presented on a combined basis and reflect the financial position, results of operations and cash flows of the real estate and agriculture businesses and corporate functions of Alexander & Baldwin, Inc., all of which were under common ownership and common management prior to the Separation. The financial statements and related financial information pertaining to the period subsequent to the Separation have been presented on a consolidated basis. The financial statements for periods prior to the Separation included herein may not necessarily reflect what A&B’s results of operations, financial position and cash flows would have been had A&B been a stand-alone company during the periods presented.

A&B is headquartered in Honolulu and, with the acquisition of Grace Pacific ("Grace") on October 1, 2013, operates four segments in three industries—Real Estate, Natural Materials and Construction and Agribusiness.

Real Estate: The Real Estate Industry consists of two segments, both of which have operations in Hawaii and on the Mainland. The Real Estate Development and Sales segment generates its revenues through the investment in and development and sale of land and commercial and residential properties. The Real Estate Leasing segment owns, operates, and manages retail, office, and industrial properties in Hawaii and on the Mainland. The Real Estate Leasing segment also leases land in Hawaii. Real estate activities are conducted through A&B Properties, Inc. and various other wholly owned subsidiaries of A&B.

Agribusiness: Agribusiness, which contains one segment, produces bulk raw sugar, specialty food grade sugars, and molasses; markets and distributes specialty food-grade sugars; provides general trucking services, mobile equipment maintenance, and repair services in Hawaii; leases agricultural land to third parties; and generates and sells electricity, to the extent not used in the Company’s Agribusiness operations. A&B is the member in Hawaiian Sugar & Transportation Cooperative (“HS&TC”), a cooperative that provides raw sugar marketing and transportation services.

Natural Materials and Construction: On October 1, 2013, the Company consummated its acquisition of Grace, a Hawaii-based natural materials and infrastructure construction company. Natural Materials and Construction, which contains one segment and includes the results of Grace from the date of acquisition, mines, processes, and sells basalt aggregate; imports sand and aggregates for sale and use; imports and markets liquid asphalt; manufactures and markets asphaltic concrete; performs asphalt paving as prime contractor and subcontractor; manufactures and supplies precast/prestressed concrete products; and provides various construction- and traffic-control- related products and services.

Reclassifications: Certain amounts reflected in the consolidated balance sheets as of December 31, 2012 have been reclassified to conform to the presentation as of December 31, 2013. Intangible assets of $8.3 million, as of December 31, 2012, was reclassified from Other assets to Intangible assets to conform to the presentation used in 2013. Additionally, the Company reclassified certain prior year amounts in the Consolidated Statements of Cash Flows, as discussed below, to improve the transparency of its cash flows. Net cash provided by (used in) operations, net cash used in investing activities and net cash provided by financing activities did not change as a result of the reclassifications.

The Company's presentation of 1031 activities in the consolidated statements of cash flows was previously treated as a non-cash investing activity, but are now reflected as additional items within cash flows from investing activities.

Rounding: Amounts in the consolidated financial statement and Notes are rounded to the nearest tenth of a million, but per-share calculations were determined based on amounts before rounding. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may be slightly different.
