1. Basis of Presentation and Description of Company

PCM, Inc. is a leading multi-vendor provider of technology products, services and solutions offered through our dedicated sales force and field service teams, direct marketing channels and a limited number of retail stores. Since our founding in 1987, we have served our customers by offering products and services from leading brands, such as Apple, Cisco, Dell, HP, Lenovo and Microsoft. We add additional value by incorporating products and services into comprehensive solutions. Our sales and marketing efforts allow our vendor partners to reach multiple customer segments including commercial businesses, state, local and federal governments, educational institutions and individual consumers.

We have prepared the unaudited consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and in conformity with accounting principles generally accepted in the United States of America, or GAAP, which requires us to make estimates and assumptions that affect amounts reported herein. We base our estimates and assumptions on historical experience and on various other factors that we believe to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, our actual results reported in future periods may be affected by changes in those estimates. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations for interim financial reporting. In the opinion of management, all adjustments, consisting only of normal recurring items which are necessary for a fair presentation, have been included. The results for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the SEC on March 18, 2013 and all of our other periodic filings, including Current Reports on Form 8-K, filed with the SEC after the end of our 2012 fiscal year and through the date of this report.

In 2012, we had four operating segments: MME, SMB, Public Sector and MacMall/OnSale. As a result of our recently effected rebranding and reorganization, in January 2013, we began operating under three operating segments - Commercial, Public Sector and MacMall. Our segments are primarily aligned based upon their respective customer base. We include corporate related expenses such as legal, accounting, information technology, product management and other administrative costs that are not otherwise included in our operating segments in Corporate & Other. All historical segment financial information provided herein has been revised to reflect these new reportable operating segments.

We sell primarily to customers in the United States, and maintain offices throughout the United States, as well as in Montreal, Canada and Manila, Philippines. In the three months ended March 31, 2013, we generated approximately 75% of our revenue in our Commercial segment, 16% of our revenue in our MacMall segment and 9% of our revenue in our Public Sector segment.

Our Commercial segment sells complex products, services and solutions to commercial businesses in the United States, using multiple sales channels, including a field relationship-based selling model, an outbound phone based sales force, a field services organization and an online extranet.

Our Public Sector segment consists of sales made primarily to federal, state and local governments, as well as educational institutions. The Public Sector segment utilizes an outbound phone and field relationship-based selling model, as well as contract and bid business development teams and an online extranet.

Our MacMall segment consists of sales made under our MacMall brand name via telephone, the Internet and four retail stores to consumers, small businesses and creative professionals, and sales made under our OnSale and eCost brand names via the Internet and inbound phone-based sales forces.

Reclassifications

We have revised the December 31, 2012 balance sheet to reduce accounts receivable and deferred revenue by $12.2 million to correct for an immaterial error resulting from the timing of the recognition of the related amounts. We had previously recognized deferred revenue when the related amounts had been billed rather than when the cash had been received in advance of product delivery. Also, we have revised the cash flow statement for the three months ended March 31, 2012 to reflect the reclassification related to the accounts receivable and deferred revenues as discussed above.
