Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of CBIZ, Inc. and its subsidiaries (“CBIZ,” the “Company,” “we,” “us,” or “our”) have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and notes required by the accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited 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. These interim unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. In the opinion of management, all adjustments of a normal recurring nature considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2016. The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. 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 and contingent purchase price obligations), 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. Changes in circumstances could cause actual results to differ materially from those estimates. A description of revenue recognition policies is included in the Annual Report on Form 10-K for the year ended December 31, 2015.

Debt Disclosure [Abstract]
Debt and Financing Arrangements	5. Debt and Financing Arrangements At June 30, 2016, CBIZ’s primary financing arrangement was the $400.0 million unsecured credit facility discussed below, which provides the Company with the capital necessary to meet its working capital needs as well as the flexibility to continue with its strategic initiatives, including business acquisitions and share repurchases. In addition to the discussion below, refer to the Annual Report on Form 10-K for the year ended December 31, 2015 for additional details of CBIZ’s debt and financing arrangements. Bank Debt CBIZ has a $400.0 million unsecured credit facility with Bank of America as agent for a group of eight participating banks that matures in July 2019. The balance outstanding under the credit facility was $235.5 million and $205.8 million at June 30, 2016 and December 31, 2015, respectively. Rates for the six months ended June 30, 2016 and 2015 were as follows: Six Months Ended June 30, 2016 2015 Weighted average rates 2.38% 2.17% Range of effective rates 1.82% - 3.50% 1.88% - 3.25% CBIZ had approximately $84.5 million of available funds under the credit facility at June 30, 2016, net of outstanding letters of credit and performance guarantees of $2.3 million. The credit facility provides CBIZ with operating flexibility and funding to support seasonal working capital needs and other strategic initiatives such as acquisitions and share repurchases. As of June 30, 2016, CBIZ was in compliance with its debt covenants. 3.125% Convertible Senior Subordinated Notes (the “2006 Notes”) During the second quarter of 2016, CBIZ redeemed the remaining 2006 Notes for $750 thousand in cash plus accrued interest under an optional early redemption provision. Interest Expense During the three and six months ended June 30, 2016 and 2015, CBIZ recognized interest expense as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Credit facility (1) $ 1,731 $ 1,165 $ 3,251 $ 2,216 2010 Notes (2) — 1,677 — 3,597 2006 Notes 2 6 8 12 Total interest expense $ 1,733 $ 2,848 $ 3,259 $ 5,825 (1) Components of interest expense related to the credit facility include amortization of deferred financing costs, commitment fees and line of credit fees. (2) Components of interest expense related to the 4.875% Convertible Senior Subordinated Notes (the “2010 Notes”) include the contractual coupon interest, amortization of discount and amortization of deferred financing costs. The 2010 Notes matured on October 1, 2015. As previously disclosed, holders received $1,000 in cash for each $1,000 principal amount of 2010 Notes along with a premium of the conversion value over par value. The $71.8 million conversion value of the 2010 Notes was determined by a cash averaging period that began on October 5, 2015 and ended on October 30, 2015. Cash payments were settled on November 4, 2015 with funds available under the credit facility.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	6. Commitments and Contingencies Letters of Credit and Guarantees CBIZ provides letters of credit to landlords (lessors) of its leased premises in lieu of cash security deposits, which totaled $2.3 million at both June 30, 2016 and December 31, 2015. In addition, CBIZ provides license bonds to various state agencies to meet certain licensing requirements. The amount of license bonds outstanding was $2.4 million and $2.3 million at June 30, 2016 and December 31, 2015, respectively. Legal Proceedings In 2010, CBIZ, Inc. and its subsidiary, CBIZ MHM, LLC (fka CBIZ Accounting, Tax & Advisory Services, LLC) (the “CBIZ Parties”), were named as defendants in lawsuits filed in the U.S. District Court for the District of Arizona and the Superior Court for Maricopa County, Arizona. The federal court case is captioned Robert Facciola, et al v. Greenberg Traurig LLP, et al, and the state court cases are captioned Victims Recovery, LLC v. Greenberg Traurig LLP, et al, Roger Ashkenazi, et al v. Greenberg Traurig LLP, et al, Mary Marsh, et al v. Greenberg Traurig LLP, et al; and ML Liquidating Trust v. Mayer Hoffman McCann PC, et al. Prior to these suits CBIZ MHM, LLC was named as a defendant in Jeffrey C. Stone v. Greenberg Traurig LLP, et al. These lawsuits arose out of the bankruptcy of Mortgages Ltd., a mortgage lender to developers in the Phoenix, Arizona area. Various other professional firms and individuals not related to the Company were also named defendants in these lawsuits. Mortgages Ltd. had been audited by Mayer Hoffman, a CPA firm that has an administrative services agreement with CBIZ. The lawsuits asserted claims against Mayer Hoffman for, among others things, violations of the Arizona Securities Act, common law fraud, and negligent misrepresentation, and sought to hold the CBIZ Parties vicariously liable for Mayer Hoffman’s conduct as either a statutory control person under the Arizona Securities Act or a joint venturer under Arizona common law. CBIZ is not a CPA firm, does not provide audits, and did not audit any of the entities at issue in these lawsuits, nor is CBIZ a control person of, or a joint venture with, Mayer Hoffman. With the exception of claims being pursued by two plaintiffs from the Ashkenazi lawsuit (“Baldino Group”), all other matters have been dismissed or settled without payment by the CBIZ Parties. The Baldino Group’s claims, which allege damages of approximately $16.0 million, are currently stayed as to the CBIZ Parties and Mayer Hoffman and no trial date has been set. The CBIZ Parties deny all allegations of wrongdoing made against them and are vigorously defending the remaining proceedings relating to the Baldino Group’s claims. In particular, the CBIZ Parties are not control persons under the Arizona Securities Act of, or in a joint venture with, Mayer Hoffman. The CBIZ Parties do not have, in any respects, the legal right to control Mayer Hoffman’s audits or any say in how the audits are conducted. The Company has been advised by Mayer Hoffman that it denies all allegations of wrongdoing made against it and that it intends to continue vigorously defending the matters. The Company cannot predict the outcome of the above matters or estimate the possible loss or range of loss, if any. Although the proceedings relating to the Baldino Group’s claims are subject to uncertainties inherent in the litigation process and the ultimate disposition of these proceedings is not presently determinable, management believes that the allegations are without merit and that the ultimate resolution of these matters will not have a material adverse effect on the consolidated financial condition, results of operations or cash flows of the Company. In addition to those items disclosed above, the Company is, from time to time, subject to claims and suits arising in the ordinary course of business. Although the ultimate disposition of such proceedings is not presently determinable, management does not believe that the ultimate resolution of these matters will have a material adverse effect on the consolidated financial condition, results of operations or cash flows of the Company.

We utilize interest rate swaps to manage interest rate risk exposure associated with our floating-rate debt under the credit facility. Under these interest rate swap contracts, we receive cash flows from counterparties at variable rates based on LIBOR and pay the counterparties a fixed rate. See the Annual Report on Form 10-K for the year ended December 31, 2015 for further discussion on CBIZ’s interest rate swaps. The following table summarizes CBIZ’s outstanding interest rate swaps and their classification in the accompanying Consolidated Balance Sheets at June 30, 2016 and December 31, 2015 (in thousands): June 30, 2016 Notional Fair Amount Value (1) Balance Sheet Location Interest rate swaps (2) $ 60,000 $ (972 ) Other non-current liabilities December 31, 2015 Notional Fair Amount Value (1) Balance Sheet Location Interest rate swaps $ 50,000 $ 240 Other non-current assets (1) See additional disclosures regarding fair value measurements in Note 8. (2) The notional value of each interest rate swap is $10.0 million, $15.0 million, $25.0 million, and $10.0 million with maturity tenors of 2, 3, 5 and 5 years, respectively. Under the terms of the interest rate swaps, CBIZ pays interest at a fixed rate of 0.885% (2-year), 1.155% (3-year), 1.300% (5-year) and 1.120% (5-year) plus applicable margin as stated in the agreement, and receives interest that varies with the one-month LIBOR.

The following table summarizes the change in Level 3 fair values of the Company’s contingent purchase price liabilities for the six months ended June 30, 2016 and 2015 (pre-tax basis) (in thousands): 2016 2015 Beginning balance – January 1 $ (24,817 ) $ (33,368 ) Additions from business acquisitions (15,088 ) (4,186 ) Settlement of contingent purchase price liabilities 6,349 5,622 Change in fair value of contingencies 714 1,400 Change in net present value of contingencies (106 ) (79 ) Ending balance – June 30 $ (32,948 ) $ (30,611 ) Contingent purchase price liabilities arise from business acquisitions and are classified as Level 3 due to the utilization of a probability weighted discounted cash flow approach to determine the fair value of the contingency. A contingent liability is established for each acquisition that has a contingent purchase price component extending over a term of two to six years. The significant unobservable input used in the fair value measurement of the contingent purchase price liabilities is the future performance of the acquired business. The future performance of the acquired business directly impacts the contingent purchase price that is paid to the seller; thus, performance that exceeds estimates would result in a higher payout, and a performance under estimates would result in a lower payout. Changes in the expected amount of potential payouts are recorded as adjustments to the initial contingent purchase price liability, with the same amount being recorded in the accompanying Consolidated Statements of Comprehensive Income. These liabilities are reviewed quarterly and adjusted if necessary. See Note 12 for further discussion of contingent purchase price liabilities. The carrying amounts of CBIZ’s cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of the short maturity of these instruments, and the carrying value of bank debt approximates fair value as the interest rate on the bank debt is variable and approximates current market rates. As a result, the fair value measurement of CBIZ’s bank debt is considered to be Level 2.

Employer Share Plans	10. Employer Share Plans Effective May 15, 2014, CBIZ shareholders approved a new plan, the CBIZ, Inc. 2014 Stock Incentive Plan (“2014 Plan”). Under the 2014 Plan, which expires in 2024, a maximum of 9.6 million stock options, shares of restricted stock or other stock-based compensation awards may be granted. Shares subject to award under the 2014 Plan may be either authorized but unissued shares of CBIZ common stock or treasury shares. Compensation expense for stock-based awards recognized during the three and six months ended June 30, 2016 and 2015 was as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Stock options $ 564 $ 534 $ 1,143 $ 1,375 Restricted stock awards 869 755 1,699 1,536 Total stock-based compensation expense $ 1,433 $ 1,289 $ 2,842 $ 2,911 Stock award activity during the six months ended June 30, 2016 was as follows (in thousands, except per share data): Stock Options Restricted Stock Awards Number of Options Weighted Average Exercise Per Share Number of Shares Weighted Grant-Date Fair Value (1) Outstanding at beginning of year 4,885 $ 7.50 962 $ 8.08 Granted 654 $ 10.35 305 $ 10.37 Exercised or released (510 ) $ 6.92 (426 ) $ 7.64 Expired or canceled (24 ) $ 7.47 (3 ) $ 7.66 Outstanding at June 30, 2016 5,005 $ 7.94 838 $ 9.13 Exercisable at June 30, 2016 2,810 $ 7.13 (1) Represents weighted average market value of the shares; awards are granted at no cost to the recipients. CBIZ utilized the Black-Scholes-Merton options-pricing model to determine the fair value of stock options on the date of grant. The fair value of stock options granted during the second quarter of 2016 was $2.40. The following weighted average assumptions were utilized: Six Months Ended June 30, Expected volatility (1) 24.88 % Expected option life (years) (2) 4.62 Risk-free interest rate (3) 1.12 % Expected dividend yield (4) 0.00 % (1) The expected volatility assumption was determined based upon the historical volatility of CBIZ’s stock price, using daily price intervals. (2) The expected option life was determined based upon CBIZ’s historical data using a midpoint scenario, which assumes all options are exercised halfway between the expirations date and the weighted average time it takes the option to vest. (3) The risk-free interest rate assumption was based upon zero-coupon U.S. Treasury bonds with a term approximating the expected life of the respective options. (4) The expected dividend yield assumption was determined in view of CBIZ’s historical and estimated dividend payouts. CBIZ does not expect to change its dividend payout policy in the foreseeable future.

Business Combinations [Abstract]
Acquisitions	12. Acquisitions The cost of an acquisition is measured at the fair value of the consideration transferred, including contingent consideration. Acquisition-related costs are recognized as an expense in the period in which they are incurred. The identifiable assets acquired, liabilities assumed and contingent consideration are measured at their fair values at the date of acquisition. Goodwill is measured as the excess of the aggregate of the consideration transferred over the net of the amounts of identifiable assets acquired and liabilities assumed. A significant portion of the goodwill is deductible for income tax purposes. The operating results of acquired businesses are included in the accompanying consolidated financial statements beginning on the date of acquisition. During the six months ended June 30, 2016, CBIZ acquired substantially all of the non-attest assets of three businesses: First quarter 2016 · Effective January 1, 2016, CBIZ acquired Millimaki Eggert, L.L.P., (“Millimaki”), located in San Diego, California. Millimaki provides professional tax, accounting, and financial services, with a specialty niche practice in the real estate sector, to closely held businesses, their owners, and mid-to-high net worth individuals. Annualized revenue attributable to Millimaki is estimated to be approximately $2.4 million. Operating results attributable to Millimaki are reported in the Financial Services practice group. Second quarter 2016 · Effective April 1, 2016, CBIZ acquired The Savitz Organization, (“Savitz”), headquartered in Philadelphia, Pennsylvania with offices in Atlanta, Georgia, and Newton, Massachusetts. Savitz is an employee retirement and health and welfare benefits firm that provides actuarial, consulting and administration outsourcing services. Annualized revenue attributable to Savitz is estimated to be approximately $20.0 million. Operating results attributable to Savitz are reported in the Employee Services practice group. · Effective June 1, 2016, CBIZ acquired Flex-Pay Business Services, Inc., (“Flex-Pay”), located in Winston-Salem, North Carolina. Flex-Pay provides payroll processing, Affordable Care Act fulfillment, and human resource solutions to more than 3,600 clients primarily in the Southeast. Annualized revenue attributable to Flex-Pay is estimated to be approximately $10.0 million. Operating results attributable to Flex-Pay are reported in the Employee Services practice group. Pro forma results of operations for these acquisitions have not been presented because the effects of the acquisitions, individually or in the aggregate, were not significant to the Company’s results. Aggregate consideration for these acquisitions consisted of approximately $33.0 million in cash consideration, $1.6 million in CBIZ common stock and $15.1 million in contingent consideration. The estimated fair values of the assets acquired and the liabilities assumed during the six months ended June 30, 2016 are as follows (in thousands): Six Months Ended June 30, 2016 Cash $ 6 Accounts receivable, net 5,313 Funds held for clients 37,230 Property and equipment, net 383 Other assets 172 Identifiable intangible assets 17,755 Current liabilities (378 ) Client fund obligations (37,230 ) Total identifiable net assets $ 23,251 Goodwill 26,471 Aggregate purchase price $ 49,722 · Under the terms of the acquisition agreements, a portion of the purchase price is contingent on future performance of the businesses acquired. · Utilizing a probability weighted income approach, CBIZ determined that the fair value of the contingent consideration arrangements for the acquisitions occurring in the first half of 2016 was $15.1 million, of which $4.4 million was recorded in “Contingent purchase price liability – current” and $10.7 million was recorded in “Contingent purchase price liability – non-current” in the accompanying Consolidated Balance Sheets at June 30, 2016. · The goodwill of $26.5 million arising from the acquisitions in the first half of 2016 consist largely of expected future earnings and cash flows from the existing management team, as well as the synergies created by the integration of the new businesses within the CBIZ organization, including cross-selling opportunities expected with the Company’s Financial Services group and the Employee Services group, to help strengthen the Company’s existing service offerings and expand the Company’s market position. · The goodwill of $26.5 million from acquisitions in the first half of 2016 is reported under the Employee Services operating segment ($25.5 million) and the Financial Services operating segment ($1.0 million). Client lists During the six months ended June 30, 2016, CBIZ purchased three clients lists, two of which are reported in the Employee Services practice group and one in the Financial Services practice group. Total consideration for these client lists was $0.2 million in cash consideration, $1.0 million of guaranteed future consideration and $0.7 million of contingent consideration. Change in contingent purchase price liability for previous acquisitions During the six months ended June 30, 2016, CBIZ decreased the fair value of the contingent purchase price liability related to prior acquisitions by $0.7 million due to lower than originally projected future results of the acquired businesses. This decrease is included in “Other income, net” in the accompanying Consolidated Statements of Comprehensive Income. Contingent earnouts for previous acquisitions CBIZ paid $4.1 million in cash and issued approximately 220,000 shares of CBIZ common stock during the six months ended June 30, 2016 for previous acquisitions. During the six months ended June 30, 2015, CBIZ acquired substantially all of the assets of one business: First quarter 2015 · Effective March 1, 2015, CBIZ acquired Model Consulting, Inc. (“Model”), located in Trevose, Pennsylvania. Model provides employee benefit consulting services to mid-sized companies in the Philadelphia and Southern New Jersey markets. Operating results attributable to Model are reported in the Employee Services practice group. Pro forma results of operations for these acquisitions have not been presented because the effects of the acquisitions, individually or in the aggregate, were not significant to the Company’s results. Aggregate consideration for this acquisition consisted of approximately $5.5 million in cash consideration and $4.2 million in contingent consideration. The estimated fair values of the assets acquired and the liabilities assumed during the six months ended June 30, 2015 are as follows (in thousands): Six Months Ended June 30, 2015 Cash $ — Accounts receivable, net — Work in process, net — Other assets — Identifiable intangible assets 2,844 Current liabilities — Total identifiable net assets $ 2,844 Goodwill 6,865 Aggregate purchase price $ 9,709 · Under the terms of the acquisition agreements, a portion of the purchase price is contingent on future performance of the businesses acquired. · The goodwill of $6.9 million arising from the acquisition in the first half of 2015 is reported under the Employee Services operating segment. Client lists During the first half of 2015, CBIZ purchased three client lists, all of which are reported in the Employee Services practice group. Total consideration for these client lists was $0.1 million in cash consideration, $0.3 million in guaranteed future consideration and $3.0 million in future consideration. Change in contingent purchase price liability for previous acquisitions During the six months ended June 30, 2015, CBIZ decreased the fair value of the contingent purchase price liability related to prior acquisitions by $1.5 million due to lower than originally projected future results of the acquired businesses. This decrease is included in “Other income, net” in the accompanying Consolidated Statements of Comprehensive Income.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations and Divestitures	13. Discontinued Operations and Divestitures CBIZ has divested, through sale or closure, business operations that do not contribute to the Company’s long-term objectives for growth or that are not complementary to its target service offerings and markets. Divestitures are classified as discontinued operations provided they meet the criteria as provided in Financial Accounting Standards Board (“FASB”) Accounting Standard Update (“ASU”) No. 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of an Entity (Topic 360)” which was effective January 1, 2015. Discontinued Operations Revenue and results from operations of discontinued operations are separately reported as “Loss from operations of discontinued operations, net of tax” in the accompanying Consolidated Statements of Comprehensive Income. During the first half of 2016, CBIZ did not discontinue the operations of any of its businesses. During the same period in 2015, the loss on operations of discontinued operations represents the results from the operations of two small businesses under the Financial Services segment that were discontinued in December 2014, one of which was sold on June 1, 2015. Revenue and results from operations of discontinued operations for the three and six months ended June 30, 2016 and 2015 were as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Revenue $ — $ 2,579 $ — $ 5,994 Loss from discontinued operations before income tax $ (437 ) $ (489 ) $ (488 ) $ (993 ) Income tax benefit (179 ) (159 ) (200 ) (328 ) Loss from discontinued operations, net of tax $ (258 ) $ (330 ) $ (288 ) $ (665 ) Divestitures Gains or losses from divested operations and assets that do not qualify for treatment as discontinued operations are recorded as “Gain on sale of operations, net” in the accompanying Consolidated Statements of Comprehensive Income. During the six months ended June 30, 2016 and 2015, CBIZ did not sell any operations. Gains totaling $0.1 million and $0.1 million for the six months ended June 30, 2016 and 2015, respectively, were recorded and relate to contingent consideration earned on sales made in previous periods.

Segment Disclosures

Segment Reporting [Abstract]
Segment Disclosures	14. Segment Disclosures CBIZ's business units have been aggregated into three practice groups: Financial Services, Employee Services and National Practices. The business units have been aggregated based on the following factors: similarity of the products and services provided to clients; similarity of the regulatory environment in which they operate; and similarity of economic conditions affecting long-term performance. The business units are managed along these segment lines. A general description of services provided by each practice group is provided in the table below. Financial Services Employee Services National Practices · Accounting · Tax · Government Health Care Consulting · Financial Advisory · Valuation · Litigation Support · Risk Advisory Services · Real Estate Advisory · Employee Benefits · Property & Casualty · Retirement Plan Services · Payroll Services · Life Insurance · Human Capital Services · Compensation Consulting · Executive Recruiting · Actuarial Services · Managed Networking and Hardware Services · Health Care Consulting Corporate and Other . Included in “Corporate and Other” are operating expenses that are not directly allocated to the individual business units. These expenses are primarily comprised of certain health care costs, gains or losses attributable to assets held in the Company’s deferred compensation plan, share-based compensation, consolidation and integration charges, certain professional fees, certain advertising costs and other various expenses. Accounting policies of the practice groups are the same as those described in Note 1 to the Annual Report on Form 10-K for the year ended December 31, 2015. Upon consolidation, intercompany accounts and transactions are eliminated, thus inter-segment revenue is not included in the measure of profit or loss for the practice groups. Performance of the practice groups is evaluated on operating income excluding those costs listed above, which are reported in “Corporate and Other.” Segment information for the three months ended June 30, 2016 and 2015 was as follows (in thousands): Three Months Ended June 30, 2016 Financial Services Employee Services National Practices Corporate and Other Total Revenue $ 122,856 $ 66,484 $ 7,675 $ — $ 197,015 Operating expenses 106,987 56,344 7,005 3,660 173,996 Gross margin 15,869 10,140 670 (3,660 ) 23,019 Corporate general & admin — — — 8,346 8,346 Operating income (loss) 15,869 10,140 670 (12,006 ) 14,673 Other income (expense): Interest expense — (10 ) — (1,723 ) (1,733 ) Gain on sale of operations, net — — — 50 50 Other (expense) income, net (27 ) 84 1 645 703 Total other (expense) income (27 ) 74 1 (1,028 ) (980 ) Income (loss) from continuing operations before income tax expense $ 15,842 $ 10,214 $ 671 $ (13,034 ) $ 13,693 Three Months Ended June 30, 2015 Financial Services Employee Services National Practices Corporate and Other Total Revenue $ 116,671 $ 61,024 $ 7,347 $ — $ 185,042 Operating expenses 102,345 51,242 6,649 2,881 163,117 Gross margin 14,326 9,782 698 (2,881 ) 21,925 Corporate general & admin — — — 6,615 6,615 Operating income (loss) 14,326 9,782 698 (9,496 ) 15,310 Other income (expense): Interest expense — (11 ) — (2,837 ) (2,848 ) Gain on sale of operations, net — — — 45 45 Other income (expense), net 8 82 1 (1,217 ) (1,126 ) Total other income (expense) 8 71 1 (4,009 ) (3,929 ) Income (loss) from continuing operations before income tax expense $ 14,334 $ 9,853 $ 699 $ (13,505 ) $ 11,381 Segment information for the nine months ended June 30, 2016 and 2015 was as follows (in thousands): Six Months Ended June 30, 2016 Financial Services Employee Services National Practices Corporate and Other Total Revenue $ 275,063 $ 130,811 $ 15,379 $ — $ 421,253 Operating expenses 220,484 110,024 13,882 7,723 352,113 Gross margin 54,579 20,787 1,497 (7,723 ) 69,140 Corporate general & admin — — — 18,591 18,591 Operating income (loss) 54,579 20,787 1,497 (26,314 ) 50,549 Other income (expense): Interest expense — (20 ) — (3,239 ) (3,259 ) Gain on sale of operations, net — — — 151 151 Other income, net 227 158 1 2,464 2,850 Total other income (expense) 227 138 1 (624 ) (258 ) Income (loss) from continuing operations before income tax expense $ 54,806 $ 20,925 $ 1,498 $ (26,938 ) $ 50,291 Six Months Ended June 30, 2015 Financial Services Employee Services National Practices Corporate and Other Total Revenue $ 260,503 $ 123,675 $ 14,730 $ — $ 398,908 Operating expenses 210,963 102,770 13,250 6,998 333,981 Gross margin 49,540 20,905 1,480 (6,998 ) 64,927 Corporate general & admin — — — 16,480 16,480 Operating income (loss) 49,540 20,905 1,480 (23,478 ) 48,447 Other income (expense): Interest expense — (20 ) — (5,805 ) (5,825 ) Gain on sale of operations, net — — — 101 101 Other income, net 107 199 1 1,426 1,733 Total other income (expense) 107 179 1 (4,278 ) (3,991 ) Income (loss) from continuing operations before income tax expense $ 49,647 $ 21,084 $ 1,481 $ (27,756 ) $ 44,456

Schedule of Fair Value Option Award Weighted Average Assumptions Used	CBIZ utilized the Black-Scholes-Merton options-pricing model to determine the fair value of stock options on the date of grant. The fair value of stock options granted during the second quarter of 2016 was $2.40. The following weighted average assumptions were utilized: Six Months Ended June 30, Expected volatility (1) 24.88 % Expected option life (years) (2) 4.62 Risk-free interest rate (3) 1.12 % Expected dividend yield (4) 0.00 % (1) The expected volatility assumption was determined based upon the historical volatility of CBIZ’s stock price, using daily price intervals. (2) The expected option life was determined based upon CBIZ’s historical data using a midpoint scenario, which assumes all options are exercised halfway between the expirations date and the weighted average time it takes the option to vest. (3) The risk-free interest rate assumption was based upon zero-coupon U.S. Treasury bonds with a term approximating the expected life of the respective options. (4) The expected dividend yield assumption was determined in view of CBIZ’s historical and estimated dividend payouts. CBIZ does not expect to change its dividend payout policy in the foreseeable future.
