Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business: CBIZ, Inc. is a diversified services company which, acting through its subsidiaries, has been providing professional business services since 1996, primarily to small and medium-sized businesses, as well as individuals, governmental entities, and not-for-profit enterprises throughout the United States and parts of Canada. CBIZ, Inc. manages and reports its operations along three practice groups; Financial Services, Benefits and Insurance Services and National Practices. A further description of products and services offered by each of the practice groups is provided in Note 16, Segment Disclosures, to the accompanying consolidated financial statements. Basis of Consolidation: The accompanying unaudited condensed consolidated financial statements include the operations of CBIZ, Inc. and all of its wholly-owned subsidiaries (“CBIZ”, the “Company”, “we”, “us”, or “our”), after elimination of all intercompany balances and transactions. These condensed 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. Unaudited Interim Financial Statements: The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. In the opinion of CBIZ management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial condition, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2018. Use of Estimates: The preparation of condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Changes in circumstances could cause actual results to differ materially from these estimates. Changes in Accounting Policies: We have consistently applied the accounting policies for the periods presented as described in Note 1, Basis of Presentation and Significant Accounting Policies, to the consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2015-14, “Revenue from Contracts with Customers” (“Topic 606”). As a result, we have changed our accounting policy for r evenue recognition as described below in Note 2, New Accounting Pronouncements.

Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	NOTE 2. New Accounting Pronouncements The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the sole source of authoritative GAAP other than the SEC issued rules and regulations that apply only to SEC registrants. The FASB issues an accounting standard to communicate changes to the FASB codification. We assess and review the impact of all accounting standards. Any accounting standards not listed below were reviewed and determined to be either not applicable or are not expected to have a material impact on the consolidated financial statements of the Company. Accounting Standards Adopted in 2018 Modification Accounting for Share-Based Payment Awards: Effective January 1, 2018, we adopted ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) – Scope of Modification Accounting.” The new standard clarifies when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. Modification accounting is required if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. We typically do not change either the terms or conditions of share-based payment awards once they are granted; therefore, the adoption of this new guidance had no impact on our consolidated financial statements. Restricted Cash - Statement of Cash Flows: Effective January 1, 2018, we adopted ASU No. 2016-18, “Statement of Cash Flows (Topic 230).” The new standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. When restricted cash is presented separately from cash and cash equivalents on the balance sheet, a reconciliation is required between the amounts presented on the statement of cash flows and the balance sheet, as well as a disclosure of information about the nature of the restrictions. The adoption of this new standard resulted in a $0.4 million decrease in net cash provided by operating activities and a $4.2 million increase in net cash provided by operating activities for the nine months ended September 30, 2018 and 2017, respectively. Restricted cash consists of funds held by us in relation to our capital and investment advisory services as those funds are restricted in accordance with applicable Financial Industry Regulatory Authority regulations. Restricted cash also consists of funds on deposit from clients in connection with the pass-through of insurance premiums to the carrier with the related liability for these funds recorded in “Accounts payable” in the accompanying Consolidated Balance Sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash as reported in the accompanying Consolidated Balance Sheets that sum to the total of the same such amount shown in the accompanying Consolidated Statements of Cash Flows (in thousands): September 30, September 30, 2018 2017 Cash and cash equivalents $ 3,493 $ 1,278 Restricted cash 32,551 32,104 Total cash, cash equivalents and restricted cash $ 36,044 $ 33,382 Statement of Cash Flows: Effective January 1, 2018, we adopted ASU No. 2016-15, “Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments.” The new standard provides guidance on eight specific cash flow issues. The application of this guidance did not have a material effect on the presentation of our Statement of Cash Flows. Revenue from Contracts with Customers: Effective January 1, 2018, we adopted Topic 606 using the modified retrospective transition method. We recognized the cumulative effect of initially applying the new standard as an adjustment directly to the opening balance of “Retained earnings” at January 1, 2018. The comparative information has not been restated and continues to be reported under the legacy standard. We evaluate our revenue contracts with customers based on the five-step model under Topic 606, pursuant to which we: (i) identify the contract with the customer; (ii) identify the performance obligation in the contract; (iii) determine the contract price; (iv) allocate the transaction price; and (v) recognize revenue when as each performance obligation is satisfied. If we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met. Revenue recognition was consistent under both the legacy standard and Topic 606 for the majority of our revenue streams, with the exception of two business units within our Benefits and Insurance Services practice group. The revenue recognition policies in our Benefits and Insurance Services practice group have been modified under the new standard as follows. • In our Property and Casualty business unit, commission revenue under agency billing arrangements (pursuant to which we bill the insured, collect the funds and remit the premium to the insurance carrier less our commissions) was previously recognized as of the later of the effective date of the insurance policy or the date billed to the customer. We now recognize the commission revenue on the effective date of the insurance policy. Also in our Property and Casualty business unit, commission revenue under direct billing arrangements (pursuant to which the insurance carrier bills the insured directly and remits the commissions to us) was previously recognized when the data necessary from the carriers was available, whereas now we recognize the commission revenue on the effective date of the insurance policy. • In our Retirement Plan Services business unit, under certain defined benefit administration arrangements we charge new clients an initial, non-refundable, set-up fee as part of a multi-year service agreement. Previously, these fees were recognized over the initial set up period, whereas now we defer the set-up fees and associated costs and recognize them over the life of the contract or the expected customer relationship, whichever is longer. The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet was as follows (in thousands): Balance at Adjustments Balance at December 31, due to January 1, Balance Sheet 2017 Topic 606 2018 ASSETS Accounts receivable, net $ 188,300 $ 9,446 $ 197,746 Other current assets 259,873 80 259,953 Other non-current assets 728,058 728 728,786 Total assets $ 1,176,231 $ 10,254 $ 1,186,485 LIABILITIES Accounts payable 51,375 6,281 57,656 Accrued personnel costs 45,264 595 45,859 Other current liabilities 237,607 113 237,720 Deferred income taxes, net 3,339 631 3,970 Other non-current liabilities 307,767 1,012 308,779 Total liabilities 645,352 8,632 653,984 STOCKHOLDERS' EQUITY Retained earnings 345,302 1,622 346,924 Other stockholders' equity 185,577 — 185,577 Total stockholders' equity 530,879 1,622 532,501 Total liabilities and stockholders' equity $ 1,176,231 $ 10,254 $ 1,186,485 The following tables summarize the impact of adopting Topic 606 on our consolidated financial statements for the periods indicated below (in thousands): Balances without September 30, 2018 Balance Sheet As reported Adjustments adoption of Topic 606 ASSETS Accounts receivable, net $ 234,906 $ (15,097 ) $ 219,809 Other current assets 188,931 (80 ) 188,851 Other non-current assets 766,019 (667 ) 765,352 Total assets $ 1,189,856 $ (15,844 ) $ 1,174,012 LIABILITIES Accounts payable $ 57,764 $ (10,276 ) $ 47,488 Accrued personnel costs 55,038 (575 ) 54,463 Other current liabilities 168,995 (114 ) 168,881 Deferred income taxes, net 5,636 (1,038 ) 4,598 Other non-current liabilities 300,508 (925 ) 299,583 Total liabilities 587,941 (12,928 ) 575,013 STOCKHOLDERS' EQUITY Retained earnings 409,467 (2,916 ) 406,551 Other stockholders' equity 192,448 — 192,448 Total shareholders' equity 601,915 (2,916 ) 598,999 Total liabilities and stockholders' equity $ 1,189,856 $ (15,844 ) $ 1,174,012 Balances without Three Months Ended September 30, 2018 Income Statement As reported Adjustments adoption of Topic 606 Revenue $ 224,249 $ (763 ) $ 223,486 Operating expenses 198,607 (14 ) 198,593 Gross margin 25,642 (749 ) 24,893 Corporate general and administrative expenses 10,279 - 10,279 Operating income 15,363 (749 ) 14,614 Other (expense) income: Interest expense (1,614 ) — (1,614 ) Gain on sale of operations, net — — — Other income, net 3,143 — 3,143 Total other expense, net 1,529 — 1,529 Income from continuing operations before income tax expense 16,892 (749 ) 16,143 Income tax expense 3,297 (168 ) 3,129 Income from continuing operations 13,595 (581 ) 13,014 Loss from discontinued operations, net of tax (9 ) — (9 ) Net income $ 13,586 $ (581 ) $ 13,005 Balances without Nine Months Ended September 30, 2018 Income Statement As reported Adjustments adoption of Topic 606 Revenue $ 722,980 $ (1,744 ) $ 721,236 Operating expenses 608,459 (43 ) 608,416 Gross margin 114,521 (1,701 ) 112,820 Corporate general and administrative expenses 30,300 — 30,300 Operating income 84,221 (1,701 ) 82,520 Other (expense) income: Interest expense (5,211 ) — (5,211 ) Gain on sale of operations, net 663 — 663 Other income, net 2,544 — 2,544 Total other expense, net (2,004 ) — (2,004 ) Income from continuing operations before income tax expense 82,217 (1,701 ) 80,516 Income tax expense 19,691 (407 ) 19,284 Income from continuing operations 62,526 (1,294 ) 61,232 Gain from discontinued operations, net of tax 17 - 17 Net income $ 62,543 $ (1,294 ) $ 61,249 Balances without Nine Months Ended September 30, 2018 Cash Flow Statement As reported Adjustments adoption of Topic 606 Cash flows from operating activities: Net income $ 62,543 $ (1,294 ) $ 61,249 Adjustments to reconcile net income to net cash provided by operating activities: 27,884 — 27,884 Changes in assets and liabilities, net of acquisitions and divestitures: — Accounts receivable, net (38,937 ) 5,651 (33,286 ) Other assets (3,474 ) (61 ) (3,535 ) Accounts payable 108 (3,995 ) (3,887 ) Accrued personnel costs 8,986 20 9,006 Other liabilities (3,134 ) (321 ) (3,455 ) Other 9,458 — 9,458 Operating cash flows provide by continuing operations 63,434 — 63,434 Operating cash flows used in discontinued operations (162 ) — (162 ) Net cash provided by operating activities 63,272 — 63,272 Net provided by investing activities 42,201 — 42,201 Net cash used in financing activities (102,838 ) — (102,838 ) Net increase in cash, cash equivalents and restricted cash 2,635 — 2,635 Cash, cash equivalents and restricted cash at beginning of year 33,409 — 33,409 Cash, cash equivalents and restricted cash at end of period $ 36,044 — $ 36,044 Accounting Standards Not Yet Adopted Internal-Use Software: In August 2018, the FASB issued ASU 2018-15, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40)," which aligns the requirements for capitalizing implementation costs incurred in a service contract hosting arrangement with those of developing or obtaining internal-use software. This standard is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently evaluating the impact the new standard will have on our consolidated financial position and results of operations. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220)” which allows the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods, with early adoption permitted. We do not expect this guidance to have a material impact on our consolidated financial position or results of operations. Derivatives and Hedging: In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” The new standard improves and simplifies accounting rules for hedge accounting to better present the economic results of an entity’s risk management activities in its financial statements and improves the disclosures of hedging arrangements. Additionally, it simplifies the hedge documentation and effectiveness assessment requirements. The updated guidance is effective for us beginning January 1, 2019. We do not expect this guidance to have a material impact on our consolidated financial position or results of operations. Leases: In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (the “New Lease Standard”) which amends the current ASC Topic 840, “Leases.” The guidance requires lessees to recognize a right-of-use asset and a lease liability for all leases (with the exception of short-term leases) on their balance sheet at the commencement date and recognize expenses on their income statement similar to the current ASC Topic 840, Leases. The New Lease Standard is effective for fiscal years and interim periods beginning after December 15, 2018. In addition, the FASB issued ASU No. 2018-11, “Leases Targeted Improvements” which provides a package of practical expedients for entities to apply upon adoption. We will adopt this standard effective January 1, 2019. We are making progress on our project plan to implement the New Lease Standard, including assessing and evaluating our portfolio of active real estate leases and surveying our business units for other leases. Additionally, we are utilizing a lease accounting software solution for both real estate and other leases to support the new reporting requirements. We are currently analyzing key lease agreement terms to extract and load into the lease accounting software solution. Although we are still finalizing our evaluation of the impact of the New Lease Standard, we expect it to have a material effect on our consolidated balance sheet. Based on the future minimum payments under non-cancellable operating leases as of September 30, 2018, we would expect to record approximately $200 million of lease related assets and liabilities, discounted to fair value, on our consolidated balance sheet with no impact on our equity. The New Lease Standard is not expected to have a material impact on our results of operations, our liquidity or our debt covenant compliance under our current credit agreements.

Clients are billed for these services based upon a fixed-fee, an hourly rate, or an outcome-based fee. Time related to the performance of all services is maintained in a time and billing system. Revenue for fixed-fee arrangements is recognized over time with the performance obligation measured in hours worked and anticipated realization. Time and expense arrangement revenue is recognized over time with progress measured towards completion with value being transferred through our hourly fee arrangement at expected net realizable rates per hour, plus agreed-upon out-of-pocket expenses. The cumulative impact on any subsequent revision in the estimated realizable value of unbilled fees for a particular client project is reflected in the period in which the change becomes known. Outcome-based arrangement revenue is fully constrained and recognized when the constraint is lifted at a point in time when the value is determined and verified by a third party. Benefits and Insurance Services Core Benefits and Insurance Services consists of group health benefits consulting, property and casualty, retirement plan services and payroll processing services. Revenue consists primarily of fee income for administering health and retirement plans and brokerage commissions. Revenue also includes investment income related to client payroll funds that are held in CBIZ accounts, as is industry practice. Under the new revenue recognition standard, the cost to obtain a contract must be capitalized unless the contract period is one year or less. We have applied a practical expedient related to commissions paid internally and continue to expense the commissions as incurred since the majority of our contract periods are one year or less. Revenue related to group health benefits consulting consists of (i) commissions, (ii) fee income which can be fixed or variable based on a price per participant and (iii) contingent revenue. • Commission revenue and fee income are recognized over the contract period as these services are provided to clients continuously throughout the term of the arrangement. Our customers benefit from each month of service on its own and although volume and the number of participants may differ month to month, the obligation to perform substantially remains the same. • Contingent revenue arrangements are related to carrier-based performance targets. Due to the uncertainty of the outcome and the probability that a change in estimate would result in a significant reversal of revenue, we have applied a constraint on recording contingent revenue. Revenue is recognized when the constraint has been lifted which is the earlier of written notification that the target has been achieved or cash collection. Contingent revenue is not a significant revenue stream to our consolidated financial position or results of operations. Revenue related to property and casualty consists of (i) commissions and (ii) contingent revenue. • Commissions relating to agency billing arrangements (pursuant to which we bill the insured, collect the funds and forward the premium to the insurance carrier less our commission) and direct billing arrangements (pursuant to which the insurance carrier bills the insured directly and forwards the commission to us) are both recognized on the effective date of the policy. Commission revenue is reported net of reserves for estimated policy cancellations and terminations. The cancellation and termination reserve is based upon estimates and assumptions using historical cancellation and termination experience and other current factors to project future experience. • Contingent revenue arrangements related to carrier-based performance targets include claim loss experience and other factors. Due to the uncertainty of the outcome and the probability that a change in estimate would result in a significant reversal of revenue, we have applied a constraint on recording contingent revenue. Revenue is recognized when the constraint has been lifted which is the earlier of written notification that the target has been achieved or cash collection. Contingent revenue is not a significant revenue stream to our consolidated financial position or results of operations. Revenue related to retirement plan services consist of advisory, third party administration and actuarial services. • Advisory revenue is based on the value of assets under management with fees recognized when the quarterly data becomes available. • Third party administration revenue is recognized over the contract period as these services are provided to clients continuously throughout the term of the arrangement. Our clients benefit from each month of service on its own, and although volume may differ month to month, the obligation to perform substantially remains the same. • Actuarial revenue is recognized over the contract period with performance measured in hours in relation to the expected total hours. Under certain defined benefit plan administration arrangements, we charge new clients an initial, non-refundable, set-up fee as part of a multi-year service agreement. Revenue and costs related to the set-up fees are deferred and recognized over the life of the contract or the expected customer relationship, whichever is longer. Revenue related to payroll processing consists of a (i) fixed fee or (ii) variable fee based on a price per employee or check processed. Revenue is recognized when the actual payroll processing occurs. Our customers benefit from each month of service on its own and although volume and the variability may differ month to month, the obligation to perform substantially remains the same. Non-core Benefits and Insurance Services consists of transactional businesses that tend to fluctuate. These include life insurance, wholesale agency benefits and talent and compensation services. National Practices Managed networking, hardware services revenue consists of installation, maintenance and repair of computer hardware. These services are charged to a single customer based on cost plus an agreed-upon markup percentage, which has existed since 1999. National Practices consulting revenue is based upon a fixed fee, an hourly rate, or a percentage of savings. Revenue for fixed fee and time and expense arrangements is recognized over the performance period based upon actual hours incurred. Transaction Price Allocated to Future Obligations The new revenue recognition standard requires us to disclose the aggregate amount of transaction price allocated to performance obligations that have not yet been satisfied as of September 30, 2018. The guidance provides certain practical expedients that limit this requirement, including performance obligations that are part of a contract that is one year or less. Since the majority of our contracts are one year or less, we have applied this practical expedient related to quantifying remaining performance obligations.

Debt and Financing Arrangements	Note 7. Debt and Financing Arrangements On April 3, 2018, we amended and restated our $400 million unsecured credit facility (as so amended and restated, the “2018 credit facility”), by and among CBIZ Operations, Inc., CBIZ, Inc., and Bank of America, N.A., as administrative agent and bank, and other participating banks. The 2018 credit facility amends and restates our credit agreement (prior to being amended and restated by the 2018 credit facility, the “2014 credit facility”), dated as of July 28, 2014, as amended by the First Amendment to credit agreement, dated as of April 10, 2015, and as amended by the Second Amendment to credit agreement, as filed on November 3, 2015. The 2018 credit facility extends the maturity date from 2019 to 2023, and continues to provide for a $400 million revolving loan commitment. The 2018 credit facility improves our borrowing margin related to leverage ratio and increases the flexibility of certain covenant baskets, as compared to the 2014 credit facility. In connection with our 2018 credit facility, we incurred approximately $1.1 million of financing costs during the second quarter of 2018, which have been deferred as other assets on our Consolidated Balance Sheets. These deferred financing costs are being amortized as interest expense on a straight line basis over the term of 2018 credit facility. The 2018 credit facility provides us with the capital necessary to meet our working capital needs as well as the flexibility to continue with our strategic initiatives, including business acquisitions and share repurchases. On August 16, 2018, we entered into an unsecured $20 million line of credit (“line of credit”) with a bank participating in our 2018 credit facility. This line of credit will be used to support our short-term funding requirements of payroll client fund obligations due to the investment of client funds, rather than liquidating client funds that have already been invested in available-for-sale securities. Refer to Note 9, Financial Instruments, for further discussion regarding these investments. The line of credit, which terminates August 16, 2019, did not have a balance outstanding at September 30, 2018. Borrowings under the line of credit bear interest at the prime rate. In addition to the discussion below, refer to our Annual Report on Form 10-K for the year ended December 31, 2017 for additional details of our debt and financing arrangements. Bank Debt The balance outstanding under the 2018 credit facility and the 2014 credit facility was $167.1 million and $178.5 million at September 30, 2018 and December 31, 2017, respectively. Rates for the nine months ended September 30, 2018 and 2017 were as follows: Nine Months Ended September 30, 2018 2017 Weighted average rates 3.07% 2.67% Range of effective rates 2.37% - 5.25% 2.19% - 4.75% We have approximately $226 million of available funds under the 2018 credit facility at September 30, 2018, net of outstanding letters of credit of $0.9 million. As of September 30, 2018, we were in compliance with our debt covenants. Interest Expense During the three months ended September 30, 2018 and 2017, interest expense under the 2018 credit facility and the 2014 credit facility was $1.6 million and $1.8 million, respectively. During the nine months ended September 30, 2018 and 2017, interest expense under the 2018 credit facility and 2014 credit facility was $5.2 million and $5 million, respectively.

In addition, we provide license bonds to various state agencies to meet certain licensing requirements. The amount of license bonds outstanding was $2.9 million and $2.5 million at September 30, 2018 and December 31, 2017, 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, P.C. (“Mayer Hoffman”), 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. The lawsuits asserted claims 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 Mortgage Ltd.’s auditor, as either a statutory control person under the Arizona Securities Act or a joint venturer under Arizona common law. With the exception of claims being pursued by two plaintiffs from the Ashkenazi lawsuit (“Baldino Group”), all other related matters have been dismissed or settled without payment by the CBIZ Parties. The Baldino Group’s claims, which allege damages of approximately $16 million, are currently stayed as to the CBIZ Parties and Mayer Hoffman, and no trial date has been set. On September 16, 2016, CBIZ, Inc. and its subsidiary CBIZ Benefits & Insurance Services, Inc. (“CBIZ Benefits”) were named as defendants in a lawsuit filed in the U.S. District Court for the Western District of Pennsylvania. The federal court case is brought by UPMC, d/b/a University of Pittsburgh Medical Center, and a health system it acquired, UPMC Altoona (formerly, Altoona Regional Health System). The lawsuit asserts professional negligence, breach of contract, and negligent misrepresentation claims against CBIZ, CBIZ Benefits and a former employee of CBIZ Benefits in connection with actuarial services provided by CBIZ Benefits to Altoona Regional Health System. The complaint seeks damages in an amount of no less than $142 million. We cannot predict the outcome of the above matters or estimate the possible loss or range of possible loss, if any. Although the proceedings are subject to uncertainties inherent in the litigation process and the ultimate disposition of these proceedings is not presently determinable, we intend to vigorously defend these cases. In addition to those items disclosed above, we are, from time to time, subject to claims and suits arising in the ordinary course of business.

All bonds are investment grade and are classified as available-for-sale. These bonds have maturity or callable dates ranging from October 2018 through November 2023, and are included in “Funds held for clients – current” in the accompanying Consolidated Balance Sheets based on our intent and ability to sell these investments at any time under favorable conditions. The following table summarizes our bond activity for the nine months ended September 30, 2018 and the twelve months ended December 31, 2017 (in thousands): Nine Months Ended Twelve Months Ended September 30, 2018 December 31, 2017 Fair value at beginning of period $ 51,101 $ 44,573 Purchases 10,745 15,546 Redemptions (1,331 ) (940 ) Maturities (7,370 ) (7,845 ) Decrease in bond premium (219 ) (160 ) Fair market value adjustment (538 ) (73 ) Fair value at end of period $ 52,388 $ 51,101 Interest Rate Swaps We do not purchase or hold any derivative instruments for trading or speculative purposes. 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 the London Interbank Offered Rate (“LIBOR”) and pay the counterparties a fixed rate. See our Annual Report on Form 10-K for the year ended December 31, 2017 for further discussion on our interest rate swaps. During the second quarter of 2018, we entered into an additional interest rate swap with a notional value of $15 million at a fixed interest rate of 2.64% maturing in 5 years. The following table summarizes our outstanding interest rate swaps and their classification in the accompanying Consolidated Balance Sheets at September 30, 2018 and December 31, 2017 (in thousands): September 30, 2018 Notional Fair Amount Value Balance Sheet Location Interest rate swaps $ 70,000 $ 2,089 Other non-current assets Interest rate swaps $ 15,000 $ 21 Other current assets December 31, 2017 Notional Fair Amount Value Balance Sheet Location Interest rate swaps $ 55,000 $ 1,055 Other non-current assets Interest rate swaps $ 15,000 $ 76 Other current assets Under the terms of the interest rate swaps, we pay interest at a fixed rate of interest plus applicable margin as stated in the agreement, and receive interest that varies with the one-month LIBOR. The notional value, fixed rate of interest and expiration date of each interest rate swap as of September 30, 2018 is (i) $15 million – 1.155% -November 2018, (ii) $25 million – 1.300% - October 2020, (iii) $10 million – 1.120% - February 2021, (iv) $20 million – 1.770% - May 2022, and (v) $15 million – 2.64% - June 2023.

The following table summarizes the change in Level 3 fair values of our contingent purchase price liabilities for the nine months ended September 30, 2018 and 2017 (pre-tax basis) (in thousands): 2018 2017 Beginning balance – January 1 $ (37,574 ) $ (33,709 ) Additions from business acquisitions (12,361 ) (17,526 ) Settlement of contingent purchase price liabilities 13,329 11,644 Change in fair value of contingencies (2,574 ) 651 Change in net present value of contingencies (716 ) (430 ) Ending balance – September 30 $ (39,896 ) $ (39,370 ) Contingent Purchase Price Liabilities Contingent purchase price liabilities result from our business acquisitions and are recorded at fair value at the time of acquisition in “Contingent purchase price liability — current” and “Contingent purchase price liability — non-current” in the accompanying Consolidated Balance Sheets. We estimate the fair value of our contingent purchase price liabilities using a probability-weighted discounted cash flow model. This fair value measure is based on significant inputs not observed in the market and thus represents a Level 3 measurement. Fair value measurements characterized within Level 3 of the fair value hierarchy are measured based on unobservable inputs that are supported by little or no market activity and reflect our own assumptions in measuring fair value. We probability weight risk-adjusted estimates of future performance of acquired businesses, then calculate the contingent purchase price based on the estimates and discount them to present value representing management’s best estimate of fair value. The fair value of the contingent purchase price liabilities are reassessed on a quarterly basis based on assumptions provided by practice group leaders and business unit controllers together with our corporate finance department. Any change in the fair value estimate is recorded in the earnings of that period. Refer to Note 14, Acquisitions, for further discussion of our acquisitions and contingent purchase price liabilities. The carrying amounts of our 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 our bank debt is considered to be Level 2.

We 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 2018 was $4.73. The following weighted average assumptions were utilized: Nine Months Ended September 30, 2018 Expected volatility (1) 22.04 % Expected option life (years) (2) 4.62 Risk-free interest rate (3) 2.80 % Expected dividend yield (4) 0.00 % (1) The expected volatility assumption was determined based upon the historical volatility of our stock price, using daily price intervals. (2) The expected option life was determined based upon our historical data using a midpoint scenario, which assumes all options are exercised halfway between the expiration date and the weighted average time for 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 our historical and estimated dividend payouts. We do not expect to change our dividend payout policy in the foreseeable future.

Three Months Ended Nine Months Ended September 30, September 30, 2018 2017 2018 2017 Numerator: Income from continuing operations $ 13,595 $ 9,864 $ 62,526 $ 46,306 Denominator: Basic Weighted average common shares outstanding 54,794 54,142 54,489 53,804 Diluted Stock options (1) 1,654 1,433 1,573 1,499 Restricted stock awards (1) 268 244 307 330 Contingent shares (2) 24 8 24 8 Diluted weighted average common shares outstanding 56,740 55,827 56,393 55,641 Basic earnings per share from continuing operations $ 0.25 $ 0.18 $ 1.15 $ 0.86 Diluted earnings per share from continuing operations $ 0.24 $ 0.18 $ 1.11 $ 0.83 (1) A total of 0.5 million and 0.3 million share based awards were excluded from the calculation of diluted earnings per share for the three and nine months ended September 30, 2018, respectively, and a total of 0.8 million and 0.4 million share based awards were excluded from the calculation of diluted earnings per share for the three and nine months ended September 30, 2017, respectively, as their effect would be anti-dilutive. (2) Contingent shares represent additional shares to be issued for purchase price earned by former owners of businesses acquired by us once future considerations have been met.

Business Combinations [Abstract]
Acquisitions	Note 14. Acquisitions Our acquisition strategy focuses on businesses with a leadership team that is committed to best in class culture, extraordinary client service and cross-serving potential. We have a long history of acquiring businesses that share common cultural values with us and provide value-added services to the small and midsize business market. The valuation of any business is a subjective process and includes industry, geography, profit margins, expected cash flows, client retention, nature of recurring or non-recurring project-based work, growth rate assumptions and competitive market conditions. 2018 During the first half of 2018, we acquired substantially all of the assets of two businesses; InR Advisory Services, LLC (“InR”), effective April 1, 2018, and Laurus Transaction Advisors, LLC (“Laurus”), effective February 1, 2018. InR, located in Media, Pennsylvania, provides investment advisory services for public and private sector clients and non-profit organizations. Operating results of InR are reported in the Benefits and Insurance Services practice group. Laurus, located in Denver, Colorado, provides financial and accounting due diligence and advisory services with respect to mergers and acquisition transactions to private equity groups and public and private sector companies. Operating results for Laurus are reported in the Financial Services practice group. Aggregate consideration for the InR and Laurus acquisitions consisted of approximately $23.4 million in cash consideration, $0.9 million in CBIZ common stock and $12.4 million in contingent consideration. Under the terms of these acquisition agreements, a portion of the purchase price is contingent on future performance of the business acquired. The maximum potential undiscounted amount of all future payments that we could be required to make under the contingent arrangements is $12.4 million, of which $3.4 million was recorded in “Contingent purchase price liability – current” and $9 million was recorded in “Contingent purchase price liability – non-current” in the accompanying Consolidated Balance Sheets at September 30, 2018. Refer to Note 10, Fair Value Measurements, for additional information regarding contingent purchase price liability fair value and fair value adjustments. Annualized revenue for these acquisitions is estimated to be approximately $9.1 million. Pro forma results of operations for these acquisitions have not been presented because the effects of the acquisitions were not significant to our “Income from continuing operations before income taxes.” 2017 During the first half of 2017, we acquired substantially all of the assets of three businesses; CMF Associates, LLC (“CMF”), effective June 1, 2017, Slaton Insurance (“Slaton”), effective June 1, 2017, and Pacific Coastal Pension and Insurance Services, Inc. (“Pacific Coastal”), effective February 1, 2017. CMF, located in Philadelphia, provides various financial consulting, executive search and deal origination services. Operating results of CMF are reported in the Financial Services practice group. Slaton, located in West Palm Beach, Florida, is a full service insurance brokerage firm offering clients a complete line of services including commercial lines, risk management and employee benefits. Pacific Coastal, located in Morgan Hill, California, provides defined contribution third party administrative and consulting services. Operating results for both Slaton and Pacific Coastal are reported in the Benefits and Insurance Services practice group. Aggregate consideration for these acquisitions consisted of approximately $23.7 million in cash consideration, $2 million in CBIZ common stock and $17.5 million in contingent consideration. The maximum potential undiscounted amount of all future payments that we could be required to make under the contingent arrangements is $17.5 million, of which $5.9 million was recorded in “Contingent purchase price liability – current” and $11.6 million was recorded in “Contingent purchase price liability – non-current” in the accompanying Consolidated Balance Sheets at September 30, 2017. Annualized revenue for these acquisitions is estimated to be approximately $23.2 million. Pro forma results of operations for these acquisitions have not been presented because the effects of the acquisitions were not significant to our “Income from continuing operations before income taxes.” The following table summarizes the amounts of identifiable assets acquired, liabilities assumed and aggregate purchase price for the acquisitions for the nine months ended September 30, 2018 and 2017 (in thousands): Nine Months Ended September 30, 2018 2017 Cash $ 306 $ 843 Accounts receivable, net 1,920 4,338 Property and equipment, net — 24 Other assets 12 151 Identifiable intangible assets 3,864 3,115 Current liabilities (1,717 ) (4,716 ) Total identifiable net assets $ 4,385 $ 3,755 Goodwill 32,255 39,460 Aggregate purchase price $ 36,640 $ 43,215 The goodwill of $32.3 million and $39.5 million arising from the acquisitions in the first nine months of 2018 and 2017, respectively, primarily resulted from expected future earnings and cash flows from the existing management team, as well as the synergies created by the integration of the new business within our organization, including cross-selling opportunities expected with our Financial Services practice group and the Benefits and Insurance Services practice group, to help strengthen our existing service offerings and expand our market position. All of the goodwill is deductible for income tax purposes. Client Lists During the nine months ended September 30, 2018, we purchased one client list, reported in the Financial Services practice group, for $0.3 million of contingent consideration. During the same period in 2017, we purchased two client lists, one of which is reported in the Benefits and Insurance practice group for $0.7 million of contingent consideration and one of which is reported in the Financial Services practice group for $0.7 million of contingent considerations. Change in Contingent Purchase Price Liability for Previous Acquisitions During the first nine months of 2018 and 2017, the fair value of the contingent purchase price liability related to prior acquisitions increased by $3.3 million and decreased by $0.2 million, respectively. The change in fair value during 2018 is mostly attributable to the change in stock price related to the mark-to-market adjustment of future common stock issuances, while the change in fair value during 2017 was due to a subsequent measurement adjustment based on projected future results of the acquired businesses. These adjustments are included in “Other income, net” in the accompanying Consolidated Statements of Comprehensive Income. Contingent Payments for Previous Acquisitions and Client Lists We paid $11 million in cash and issued approximately 0.1 million shares of our common stock during the nine months ended September 30, 2018 for previous acquisitions, compared to $4.8 million in cash and approximately 0.2 million shares of our common stock during the same period in 2017. For the first nine months of 2018 and 2017, we paid approximately $1.1 million and $1 million in cash for previous client list purchases.

Discontinued Operations And Disposal Groups [Abstract]
Discontinued Operations and Divestitures	We will divest (through sale or closure) business operations that do not contribute to our long-term objectives for growth, or that are not complementary to our target service offerings and markets. Discontinued operations primarily consisted of two small businesses under the Financial Services segment that were sold in 2015. During the first nine months of both 2018 and 2017, we did not discontinue the operations of any of our businesses. 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. We recorded a gain of $0.7 million in the first nine months of 2018, related to a small book of business under the Benefits and Insurance Services practice group.

Segment Disclosures	Sep. 30, 2018
Segment Reporting [Abstract]
Segment Disclosures	Note 16. Segment Disclosures Our business units have been aggregated into three practice groups: Financial Services, Benefits and Insurance 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 Benefits and Insurance Services National Practices • Accounting and Tax • Government Healthcare Consulting • Financial Advisory • Valuation • Risk & Advisory Services • Group Health Benefits Consulting • Payroll • Property & Casualty • Retirement Plan Services • Managed Networking and Hardware Services • Healthcare 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 our non-qualified 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, Basis of Presentation and Significant Accounting Policies, to the Annual Report on Form 10-K for the year ended December 31, 2017. 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 the “Corporate and Other” segment. Segment information for the three and nine months ended September 30, 2018 and 2017 is presented below. We do not manage our assets on a segment basis, therefore segment assets are not presented below.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
Summary of Significant Accounting Policies (Policies)	Sep. 30, 2018
Accounting Policies [Abstract]
Description of Business	Description of Business: CBIZ, Inc. is a diversified services company which, acting through its subsidiaries, has been providing professional business services since 1996, primarily to small and medium-sized businesses, as well as individuals, governmental entities, and not-for-profit enterprises throughout the United States and parts of Canada. CBIZ, Inc. manages and reports its operations along three practice groups; Financial Services, Benefits and Insurance Services and National Practices. A further description of products and services offered by each of the practice groups is provided in Note 16, Segment Disclosures, to the accompanying consolidated financial statements.
Basis of Consolidation	Basis of Consolidation: The accompanying unaudited condensed consolidated financial statements include the operations of CBIZ, Inc. and all of its wholly-owned subsidiaries (“CBIZ”, the “Company”, “we”, “us”, or “our”), after elimination of all intercompany balances and transactions. These condensed 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.
Unaudited Interim Financial Statements	Unaudited Interim Financial Statements: The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. In the opinion of CBIZ management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial condition, results of operations, and cash flows for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2018.
Use Of Estimates	Use of Estimates: The preparation of condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Changes in circumstances could cause actual results to differ materially from these estimates.
Changes in Accounting Policies	Changes in Accounting Policies: We have consistently applied the accounting policies for the periods presented as described in Note 1, Basis of Presentation and Significant Accounting Policies, to the consolidated financial statements contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017. Effective January 1, 2018, we adopted Accounting Standards Update (“ASU”) No. 2015-14, “Revenue from Contracts with Customers” (“Topic 606”). As a result, we have changed our accounting policy for r evenue recognition as described below in Note 2, New Accounting Pronouncements.
New Accounting Pronouncements	The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the sole source of authoritative GAAP other than the SEC issued rules and regulations that apply only to SEC registrants. The FASB issues an accounting standard to communicate changes to the FASB codification. We assess and review the impact of all accounting standards. Any accounting standards not listed below were reviewed and determined to be either not applicable or are not expected to have a material impact on the consolidated financial statements of the Company. Accounting Standards Adopted in 2018 Modification Accounting for Share-Based Payment Awards: Effective January 1, 2018, we adopted ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) – Scope of Modification Accounting.” The new standard clarifies when a change to the terms or conditions of a share-based payment award must be accounted for as a modification. Modification accounting is required if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. We typically do not change either the terms or conditions of share-based payment awards once they are granted; therefore, the adoption of this new guidance had no impact on our consolidated financial statements. Restricted Cash - Statement of Cash Flows: Effective January 1, 2018, we adopted ASU No. 2016-18, “Statement of Cash Flows (Topic 230).” The new standard requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. When restricted cash is presented separately from cash and cash equivalents on the balance sheet, a reconciliation is required between the amounts presented on the statement of cash flows and the balance sheet, as well as a disclosure of information about the nature of the restrictions. The adoption of this new standard resulted in a $0.4 million decrease in net cash provided by operating activities and a $4.2 million increase in net cash provided by operating activities for the nine months ended September 30, 2018 and 2017, respectively. Restricted cash consists of funds held by us in relation to our capital and investment advisory services as those funds are restricted in accordance with applicable Financial Industry Regulatory Authority regulations. Restricted cash also consists of funds on deposit from clients in connection with the pass-through of insurance premiums to the carrier with the related liability for these funds recorded in “Accounts payable” in the accompanying Consolidated Balance Sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash as reported in the accompanying Consolidated Balance Sheets that sum to the total of the same such amount shown in the accompanying Consolidated Statements of Cash Flows (in thousands): September 30, September 30, 2018 2017 Cash and cash equivalents $ 3,493 $ 1,278 Restricted cash 32,551 32,104 Total cash, cash equivalents and restricted cash $ 36,044 $ 33,382 Statement of Cash Flows: Effective January 1, 2018, we adopted ASU No. 2016-15, “Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments.” The new standard provides guidance on eight specific cash flow issues. The application of this guidance did not have a material effect on the presentation of our Statement of Cash Flows. Revenue from Contracts with Customers: Effective January 1, 2018, we adopted Topic 606 using the modified retrospective transition method. We recognized the cumulative effect of initially applying the new standard as an adjustment directly to the opening balance of “Retained earnings” at January 1, 2018. The comparative information has not been restated and continues to be reported under the legacy standard. We evaluate our revenue contracts with customers based on the five-step model under Topic 606, pursuant to which we: (i) identify the contract with the customer; (ii) identify the performance obligation in the contract; (iii) determine the contract price; (iv) allocate the transaction price; and (v) recognize revenue when as each performance obligation is satisfied. If we determine that a contract with enforceable rights and obligations does not exist, revenues are deferred until all criteria for an enforceable contract are met. Revenue recognition was consistent under both the legacy standard and Topic 606 for the majority of our revenue streams, with the exception of two business units within our Benefits and Insurance Services practice group. The revenue recognition policies in our Benefits and Insurance Services practice group have been modified under the new standard as follows. • In our Property and Casualty business unit, commission revenue under agency billing arrangements (pursuant to which we bill the insured, collect the funds and remit the premium to the insurance carrier less our commissions) was previously recognized as of the later of the effective date of the insurance policy or the date billed to the customer. We now recognize the commission revenue on the effective date of the insurance policy. Also in our Property and Casualty business unit, commission revenue under direct billing arrangements (pursuant to which the insurance carrier bills the insured directly and remits the commissions to us) was previously recognized when the data necessary from the carriers was available, whereas now we recognize the commission revenue on the effective date of the insurance policy. • In our Retirement Plan Services business unit, under certain defined benefit administration arrangements we charge new clients an initial, non-refundable, set-up fee as part of a multi-year service agreement. Previously, these fees were recognized over the initial set up period, whereas now we defer the set-up fees and associated costs and recognize them over the life of the contract or the expected customer relationship, whichever is longer.

This standard is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently evaluating the impact the new standard will have on our consolidated financial position and results of operations. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income: In February 2018, the FASB issued ASU No. 2018-02, “Income Statement – Reporting Comprehensive Income (Topic 220)” which allows the reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods, with early adoption permitted. We do not expect this guidance to have a material impact on our consolidated financial position or results of operations. Derivatives and Hedging: In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities.” The new standard improves and simplifies accounting rules for hedge accounting to better present the economic results of an entity’s risk management activities in its financial statements and improves the disclosures of hedging arrangements. Additionally, it simplifies the hedge documentation and effectiveness assessment requirements. The updated guidance is effective for us beginning January 1, 2019. We do not expect this guidance to have a material impact on our consolidated financial position or results of operations. Leases: In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (the “New Lease Standard”) which amends the current ASC Topic 840, “Leases.” The guidance requires lessees to recognize a right-of-use asset and a lease liability for all leases (with the exception of short-term leases) on their balance sheet at the commencement date and recognize expenses on their income statement similar to the current ASC Topic 840, Leases. The New Lease Standard is effective for fiscal years and interim periods beginning after December 15, 2018. In addition, the FASB issued ASU No. 2018-11, “Leases Targeted Improvements” which provides a package of practical expedients for entities to apply upon adoption. We will adopt this standard effective January 1, 2019. We are making progress on our project plan to implement the New Lease Standard, including assessing and evaluating our portfolio of active real estate leases and surveying our business units for other leases. Additionally, we are utilizing a lease accounting software solution for both real estate and other leases to support the new reporting requirements. We are currently analyzing key lease agreement terms to extract and load into the lease accounting software solution. Although we are still finalizing our evaluation of the impact of the New Lease Standard, we expect it to have a material effect on our consolidated balance sheet. Based on the future minimum payments under non-cancellable operating leases as of September 30, 2018, we would expect to record approximately $200 million of lease related assets and liabilities, discounted to fair value, on our consolidated balance sheet with no impact on our equity. The New Lease Standard is not expected to have a material impact on our results of operations, our liquidity or our debt covenant compliance under our current credit agreements.

Schedule of Fair Value Option Award Weighted Average Assumptions Used	We 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 2018 was $4.73. The following weighted average assumptions were utilized: Nine Months Ended September 30, 2018 Expected volatility (1) 22.04 % Expected option life (years) (2) 4.62 Risk-free interest rate (3) 2.80 % Expected dividend yield (4) 0.00 % (1) The expected volatility assumption was determined based upon the historical volatility of our stock price, using daily price intervals. (2) The expected option life was determined based upon our historical data using a midpoint scenario, which assumes all options are exercised halfway between the expiration date and the weighted average time for 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 our historical and estimated dividend payouts. We do not expect to change our dividend payout policy in the foreseeable future.
