1.	Summary of Significant Accounting Policies

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements.

In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting solely of normal recurring adjustments) considered necessary to present fairly the financial position of CBIZ, Inc. and its consolidated subsidiaries (“CBIZ” or the “Company”) as of June 30, 2013 and December 31, 2012, the consolidated results of their operations for the three and six months ended June 30, 2013 and 2012, and the cash flows for the six months ended June 30, 2013 and 2012. Due to seasonality, potential changes in economic conditions, interest rate fluctuations and other factors, the results of operations for such interim periods are not necessarily indicative of the results for the full year. For further information, refer to the consolidated financial statements and notes thereto included in CBIZ’s Annual Report on Form 10-K for the year ended December 31, 2012.

Divestiture of Medical Management Professionals

On July 26, 2013, CBIZ, through its subsidiary CBIZ Operations, Inc., an Ohio Corporation, entered into an agreement with Zotec Partners, LLC, an Indiana limited liability company, to sell all of the issued and outstanding capital stock of each of CBIZ Medical Management Professionals, Inc., an Ohio corporation, and CBIZ Medical Management, Inc., a North Carolina corporation, and substantially all of the stock of their subsidiary companies, collectively consisting of all of CBIZ’s Medical Management Professionals ongoing operations and business (“MMP”) for a purchase price of approximately $200 million, which amount is subject to adjustment. Subject to customary closing conditions and regulatory approvals, the transaction is expected to close on September 1, 2013. After transaction costs and taxes, CBIZ expects proceeds to be approximately $145 million. As a result of the sale agreement, the assets and liabilities as well as the operations of MMP are reflected as discontinued operations in this Form 10-Q. See Note 13 for further discussion of discontinued operations and divestitures.

Principles of Consolidation

The accompanying consolidated financial statements reflect the operations of CBIZ, Inc. and all of its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements do not reflect the operations or accounts of variable interest entities as the impact is not material to the financial condition, results of operations or cash flows of CBIZ. See CBIZ’s Annual Report on Form 10-K for the year ended December 31, 2012 for further discussion.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenue and expenses. Management’s estimates and assumptions include, but are not limited to, estimates of collectability of accounts receivable and unbilled revenue, the realizability of goodwill and other intangible assets, the fair value of certain assets, the valuation of stock options in determining compensation expense, estimates of accrued liabilities (such as incentive compensation, self-funded health insurance accruals, legal reserves, income tax uncertainties, contingent purchase price obligations, and consolidation and integration reserves), the provision for income taxes, the realizability of deferred tax assets, and other factors. Management’s estimates and assumptions are derived from and are continually evaluated based upon available information, judgment and experience. Actual results could differ from those estimates.

Revenue Recognition and Valuation of Unbilled Revenues

Revenue is recognized only when all of the following are present: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the fee to the client is fixed or determinable, and collectability is reasonably assured.

CBIZ offers a vast array of products and business services to its clients. Those services are delivered through three practice groups. A description of revenue recognition policies is included in the Annual Report on Form 10-K for the year ended December 31, 2012.
