Description of Business and Significant Accounting Policies	'
	NOTE 1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
	Description of Business
	TriNet Group, Inc. (the Company or TriNet), a Delaware corporation incorporated in January 2000, provides a comprehensive human resources solution for small to medium-sized businesses. The Company’s solution includes payroll processing, human capital consulting, employment law compliance and employee benefits, including health insurance, retirement plans and workers compensation insurance.
	The Company provides its services through co-employment relationships with its customers, under which the Company and its customers each take responsibility for certain portions of the employer-employee relationship for worksite employees (WSEs). The Company is the employer of record for most administrative and regulatory purposes, including the following: (i) compensation through wages and salaries; (ii) employer payroll-related taxes payment; (iii) employee payroll-related taxes withholding and payment; (iv) employee benefit programs including health and life insurance, and others; and (v) workers compensation coverage.
	Initial Public Offering
	In March 2014, the Company completed its initial public offering (IPO) in which the Company issued and sold 15,000,000 shares of common stock at a public offering price of $16.00 per share. In addition, another 2,250,000 shares were sold by certain selling stockholders pursuant to the underwriters’ option to purchase additional shares.  The Company received net proceeds of approximately $217.6 million, after deducting underwriting discounts and commissions of $16.8 million and offering expenses of $5.6 million. The Company did not receive any proceeds from the sale by the selling stockholders.  Upon the closing of the IPO, all shares of the Company’s then-outstanding preferred stock were converted into an aggregate of 38,065,708 shares of common stock.
	Segment Information
	The Company operates in one reportable segment in accordance with ASC 280. All of the Company’s service revenues are generated from external customers. Less than 1% of revenues are generated outside of the United States of America (U.S.). Substantially all of the Company’s long-lived assets are located in the U.S.
	Basis of Presentation
	The accompanying unaudited consolidated financial statements and footnotes thereto of the Company and its wholly owned subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (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. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 with the SEC on March 27, 2014. There have been no changes to the Company’s significant accounting policies described in the prospectus that have had a material impact on our consolidated financial statements and related notes. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated balance sheets present the current assets and current liabilities directly related to the processing of human resources transactions as WSE-related assets and WSE-related liabilities, respectively. WSE-related assets comprise cash and investments restricted for current workers compensation claim payments, payroll funds collected, accounts receivable, unbilled service revenues, and refundable or prepaid amounts related to the Company-sponsored workers compensation and health plan programs. WSE-related liabilities comprise customer prepayments, wages and payroll taxes accrued and payable, and liabilities related to the Company-sponsored workers compensation and health plan programs resulting from workers compensation case reserves, premium amounts due to providers for enrolled employees, and workers compensation and health reserves that are expected to be disbursed within the next 12 months.
	The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for fair presentation. The results of the six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014.
	Seasonality
	Historically, the Company has experienced its highest monthly addition of WSEs, as well as its highest monthly levels of client attrition, in the month of January, primarily because clients that change their payroll service providers tend to do so at the beginning of a calendar year. In addition, the Company experiences higher levels of client attrition in connection with renewals of the health insurance it provides for its WSEs, in the event that such renewals result in increased premiums that it passes on to its clients. The Company has also historically experienced higher insurance claim volumes in the second and third quarters of a fiscal year than in the first and fourth quarters of a fiscal year, as WSEs typically access their health care providers more often in the second and third quarters of a fiscal year, which has negatively impacted the Company’s insurance costs in these quarters. These historical trends may change, and other seasonal trends may develop that make it more difficult for the Company to manage its business.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. These estimates include, but are not limited to, allowances for accounts receivable, workers compensation related assets and liabilities, health plan assets and liabilities, recoverability of goodwill and other intangible assets, income taxes, stock-based compensation and other contingent liabilities. Such estimates are based on historical experience and on various other assumptions that Company management believes to be reasonable under the circumstances. Actual results could differ from those estimates.
	Recent Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-12—Compensation-Stock Compensation, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted. The amendments may be applied prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented. The Company does not expect this guidance to have a material effect on its consolidated financial statements. The Company expects to adopt this guidance in 2016.
	In May 2014, the FASB issued ASU 2014-09—Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance under GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. The amendments may be applied retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company expects to adopt this guidance in 2017. The Company has not yet selected a method of adoption and is currently evaluating the effect that the amendments will have on the consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires that an unrecognized tax benefit, or portion of an unrecognized tax benefit, be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If an applicable deferred tax asset is not available or a company does not expect to use the applicable deferred tax asset, the unrecognized tax benefit should be presented as a liability in the financial statements and should not be combined with an unrelated deferred tax asset. ASU 2013-11 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date, however retrospective application is permitted. The Company adopted this guidance in 2014. The adoption of ASU 2013-11 did not have a material impact on the Company’s consolidated financial statements.

	Current portion included in worksite employer-related liability		34,979			23,453
	Long term portion	$	56,253		$	45,309
	Under the terms of its agreements with its workers compensation insurance carriers, the Company collects and holds premiums in restricted accounts pending claims payments by the claims administrator. As of June 30, 2014 and December 31, 2013, such restricted amounts of $50.3 million and $21.5 million, respectively, are presented as restricted cash and restricted investment within WSE-related assets in the accompanying consolidated balance sheets. In addition, the Company invests premium collateral in excess of short term claim obligations in certain longer term securities. While it is the intention of the Company to reinvest maturing securities, periodically certain securities will be classified as short term to the extent the Company does not intend to reinvest the proceeds upon maturity.  At June 30, 2014 and December 31, 2013, $43.5 million and $37.0 million, respectively, are presented as restricted long-term investments.

Marketable Securities and Fair Value Measurements	'
	NOTE 4. MARKETABLE SECURITIES AND FAIR VALUE MEASUREMENTS
	The Company’s noncurrent restricted cash and investments include $43.1 million of available-for-sale marketable securities and $0.4 million of cash collateral at June 30, 2014. The Company’s restricted investments within WSE-related assets include $10.0 million of available-for-sale marketable securities and $2.3 million of certificates of deposit as of June 30, 2014. The available-for-sale marketable securities as of June 30, 2014 and December 31, 2013 consist of the following (in thousands):
		Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value
	30-Jun-14
	U.S. treasuries	$	52,566	$	62	$	(12	)	$	52,616
	Mutual funds		500		9		–			509
	Total investments	$	53,066	$	71	$	(12	)	$	53,125
	December 31, 2013:
	U.S. treasuries	$	35,900	$	38	$	(20	)	$	35,918
	Mutual funds		500		8	–				508
	Total investments	$	36,400	$	46	$	(20	)	$	36,426
	There were no realized gains or losses for the three and six months ended June 30, 2014 and 2013. As of June 30, 2014 and December 31, 2013, the contractual maturities of the U.S. treasuries were two to three years.
	As of June 30, 2014, certain of the Company’s U.S. treasuries were in unrealized loss position principally due to changes in interest rates and credit spreads. No U.S. treasuries were in an unrealized loss position for more than 12 months as of either June 30, 2014 or December 31, 2013. In analyzing an issuer’s financial condition, the Company considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts’ reports. The fair value of these securities in an unrealized loss position represented 39% of the total fair value of all securities available for sale and their unrealized loss was $0.01 million as of June 30, 2014. As the Company has the ability to hold debt securities until maturity, or for the foreseeable future as classified as available for sale, no decline was deemed to be other-than-temporary.
	Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.
	As a basis for considering such assumptions, the Company uses a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
	·	Level I—observable inputs such as quoted prices in active markets
	·	Level II—inputs other than the quoted prices in active markets that are observable either directly or indirectly
	·	Level III—unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions
	This hierarchy requires the Company to use observable market data when available and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures its financial assets at fair value.
	The following table summarizes the Company’s financial assets measured at fair value on a recurring basis (in thousands):
		Total		Level I		Level II			Level III

	There were no transfers between Level I and Level II assets for the three months ended June 30, 2014 or the year ended December 31, 2013.
	As of June 30, 2014 and December 31, 2013, certificate of deposit consisted of certificates of deposit held by domestic financial institutions, which are presented as restricted investments within WSE-related assets in the accompanying consolidated balance sheets.
	The book value of the Company’s financial instruments not measured at fair value, including cash, restricted cash, WSE-related assets and liabilities, line of credit and accrued corporate wages, approximates fair value due to the relatively short maturity, cash repayments or market interest rates of such instruments. The fair value of such financial instruments, other than cash and restricted cash, is determined using the income approach based on the present value of estimated future cash flows. The fair value of all of these instruments would be categorized as Level II of the fair value hierarchy, with the exception of cash and cash equivalents, which would be categorized as Level I.
	At June 30, 2014 and December 31, 2013, the carrying value of our notes payable of $575.4 million and $818.4 million, respectively, approximated fair value. The estimate fair values of our notes payable are considered a Level II valuation in the hierarchy for fair value measurement and are based on a cash flow model discounted at market interest rates that considers the underlying risks of unsecured debt.

	In August 2013, the Company, as guarantor, its subsidiary TriNet HR Corporation, as borrower, and certain of its other subsidiaries as subsidiary guarantors entered into two senior secured credit facilities:
	·	a $705.0 million first lien credit facility with JPMorgan Chase Bank, N.A., as administrative agent; and
	·	a $190.0 million second lien credit facility with Wilmington Trust, National Association, as administrative agent.
	The credit facilities are secured by substantially all of the Company’s assets and the assets of the borrower and of the subsidiary guarantors, other than specifically excluded assets.
	The first lien credit facility provides for a five-year revolving credit facility of $75.0 million, three-year first lien tranche B-1 term loan of $175.0 million and seven-year first lien tranche B-2 term loan of $455.0 million. A second lien credit facility provides for seven-year-and-six-month term loan of $190.0 million. All first lien and second lien term loans were fully drawn in August 2013. The $75.0 million revolving credit facility includes capacity for a $30.0 million letter of credit facility and a $10.0 million swingline facility. The total unused portion of the revolving credit facility was $59.5 million as of June 30, 2014. The proceeds of the first and second lien credit facilities were used to repay approximately $448.3 million of indebtedness outstanding under the Company’s previous credit facility, declare a special dividend, provide cash collateral to guarantee a letter of credit and pay transaction costs. In connection with the credit facilities, the Company incurred $23.1 million of debt issuance costs, which were deferred and are being amortized over the term of the credit facilities.
	In March 2014, the proceeds from the IPO were used to fully repay the $190.0 million second lien credit facility, which resulted in a prepayment premium of $3.8 million, and to repay $25.0 million of the first lien tranche B-1 term loan. Additionally, the remaining balance of the loan fees associated with the second lien credit facility and a portion of the loan fees associated with the first lien credit facility were fully amortized in March 2014 for a charge of $5.0 million. In May 2014, the Company repaid $25.0 million of the first lien tranche B-1 term loan. As a result, a portion of the loan fees associated with the first lien credit facility were fully amortized in May 2014 for a charge of $0.5 million.
	The credit facilities contain customary representations and warranties and customary affirmative and negative covenants applicable to us and our subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness, and dividends and other distributions. Under the revolving credit facility, so long as there are any outstanding revolving loans and/or outstanding letters of credit in excess of $15.0 million other than letters of credit that have been cash collateralized, we are required to comply with a financial covenant that requires us and our subsidiaries to maintain a maximum first lien leverage ratio at 5.25 to 1.00 on a consolidated basis as of June 30, 2014. The Company was in compliance with the restrictive covenants under the credit facilities at June 30, 2014. The company amended and restated the credit facility in July 2014 as discussed in Note 11.

	Equity-Based Incentive Plans
	In 2000, the Company established the 2000 Equity Incentive Plan (the 2000 Plan), which provided for granting incentive stock options, nonstatutory stock options, bonus awards and restricted stock awards to eligible employees, directors, and consultants of the Company. In December 2009, the Board of Directors approved the 2009 Equity Incentive Plan (the 2009 Plan) as the successor to and continuation of the 2000 Plan. As of the 2009 Plan effective date, remaining shares available for issuance under the 2000 Plan were cancelled and became available for issuance under the 2009 Plan. No additional stock awards will be granted under the 2000 Plan. The 2009 Plan provides for the grant of the following awards to eligible employees, directors, and consultants: incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards, and other stock awards. Incentive stock options may only be granted to employees. Nonemployee directors are eligible to receive nonstatutory stock options automatically at designated intervals over their period of continuous service on the Board. In February 2014, the Board approved an amendment to the 2009 Plan authorizing an additional 3,000,000 shares available for grant. The amended 2009 Plan also provides that the number of shares reserved for issuance under the 2009 Plan will increase on January 1 of each year for a period of up to five years by 4.5% of the total number of shares of capital stock outstanding on December 31 of the preceding calendar year, which will begin on January 1, 2015 and continue through January 1, 2019.
	The exercise price per share of all incentive stock options granted under the 2000 Plan and the 2009 Plan must be at least equal to the fair market value of the shares at the date of grant as determined by the Board of Directors. Options issued to recipients other than nonemployee directors generally vest over four years with a one year cliff and monthly thereafter, and have a maximum contractual term of 10 years. Options issued to members of the Board of Directors are issued with varying vesting schedules. Incentive stock options granted at 110% of the fair market value to stockholders who have greater than 10% ownership have a maximum term of five years.
	The Company also has granted restricted stock units to members of the Board of Directors and certain executives. These restricted stock units represent rights to receive shares of the Company’s common stock on satisfaction of applicable vesting conditions. The fair value of restricted stock units is equal to the fair value of the Company’s common stock on the date of grant. The restricted stock units vest at a rate of 25% at the end of the first year and then pro rata monthly thereafter over the remaining vesting term of three or two years, as applicable.
	Stock option plan activity under the 2000 Plan and the 2009 Plan for the six months ended June 30, 2014 is summarized as follows:

	Stock Split
	On March 7, 2014, the Company’s board of directors and stockholders approved and effected an amendment to the amended and restated certificate of incorporation providing for a 2-for-1 stock split of the outstanding common stock. All of the share numbers, share prices, and exercise prices have been adjusted within these financial statements, on a retroactive basis, to reflect this 2-for-1stock split.
	Employee Stock Purchase Plan
	The Company adopted the 2014 Employee Stock Purchase Plan (ESPP) in February 2014, which became effective on March 26, 2014. The ESPP was approved with a reserve of 1.1 million shares of common stock for future issuance under various terms provided for in the ESPP, which will automatically increase on January 1 of each year from 2015 through 2024 by the lesser of 1% of the total number of shares outstanding on December 31 of the preceding calendar year or 1,800,000 shares. We commenced our first purchase period under the ESPP on March 26, 2014 with the purchase price at the lesser of 85% of the fair market value of the common stock on the offering date and 85% of the fair market value of the common stock on the applicable purchase date.  Offering periods will be six months in duration and will end on or about May 15 and November 15 of each year, with the exception of the initial offering period which commenced on March 26, 2014 and that ends on November 14, 2014.

Income Taxes	'
	NOTE 9. INCOME TAXES
	The Company is subject to taxation in the United States and Canada. However, business is conducted primarily in the United States. The effective tax rate differs from the statutory rate primarily due to state taxes, tax credits and changes in uncertain tax positions. The Company makes estimates and judgments about its future taxable income that are based on assumptions that are consistent with the Company’s plans and estimates. Should the actual amounts differ from these estimates, the amount of the valuation allowance could be materially affected.
	Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. Changes in valuation allowances are reflected as a component of provision for income taxes.
	The Company’s effective tax rate (ETR) was 44.2% and 38.4% for the three months ended June 30, 2014 and 2013, respectively. The Company’s ETR was 47.1% and 36.8% for the six months ended June 30, 2014 and 2013, respectively. The increase is primarily due to non-deductible stock-based compensation and for the revaluation of deferred taxes, based on a regulatory state tax change enacted during the three months ended March 31, 2014.   The remainder of the increase is primarily due to the expiration of the federal research and development tax credit in 2014, as well as a release of uncertain tax positions recognized for the three months ended March 31, 2013
	The Company has not been subject to U.S. federal, state and local income tax examinations by tax authorities in material jurisdictions for tax years beginning prior to January 1, 2009.  However, there are outstanding Notices of Proposed Assessment disallowing employment tax credits totaling $10.5 million in connection with the Internal Revenue Service (IRS) examination of Gevity HR, Inc. and Subsidiaries, which was acquired by TriNet on June 1, 2009.  While Appeals has denied the credits, and the Company plans to exhaust all administrative efforts to resolve this issue, it is likely that the matter will ultimately be resolved through litigation.  With regard to these employment tax credits, the Company believes it is more likely than not that the Company will prevail.  Therefore, no reserve has been recognized related to this matter.

	Lease Commitments
	The Company leases office facilities, including its headquarters and other facilities, and equipment under non-cancelable operating leases. The Company also leases certain software and furniture, fixtures, and equipment under capital leases. The lease agreements generally provide for rental payments on a graduated basis and for options to renew, which could increase future minimum lease payments if exercised. The Company recognizes rent expense on a straight-line basis over the lease period and accrues for rent expense incurred but not paid. Rent expense for the three months ended June 30, 2014 and 2013 was $2.9 million and $2.2 million, respectively. Rent expense for the six months ended June 30, 2014 and 2013 was $5.7 million and $4.4 million, respectively.
	Operating Covenants
	To meet various states’ licensing requirements and maintain accreditation by Employer Services Assurance Corporation, the Company is subject to various minimum working capital and net worth requirements. As of June 30, 2014, the Company believes it has fully complied in all material respects with all applicable state regulations regarding minimum net worth, working capital and all other financial and legal requirements. Further, the Company has maintained positive working capital throughout the period covered by the financial statements.
	Contingencies
	The Company may from time to time become involved in various litigation matters arising in the ordinary course of business, including suits by its clients. The unfavorable resolution of any such matter could have a material effect on the Company’s consolidated financial position and results of operations.
	Due to the nature of the Company’s relationship with its WSEs, the Company could be subject to liability for federal and state law violations even if the Company does not participate in such violations. While the Company’s agreements with its clients contain indemnification provisions related to the conduct of its clients, the Company historically has not encountered situations requiring enforcement of these indemnification provisions.
	The Company has been named as a defendant in various class action lawsuits arising from the nature of the Company’s relationship with its WSEs. At this stage of the lawsuits, management believes an unfavorable outcome to the Company is not probable. There are significant uncertainties involved in any class action litigation. Management is unable to estimate a possible loss or range of loss for these class action lawsuits.

	2014 Credit Facility
	On July 9, 2014, the Company amended and restated its first lien credit facility pursuant to an amended and restated first lien credit agreement (the Amended and Restated Credit Agreement).The Amended and Restated Credit Agreement provides for: (i) $375 million principal amount of “tranche A term loans,” (ii) $200 million principal amount of “tranche B term loans,” and (iii) a revolving credit facility of $75 million. The proceeds of the tranche A term loans were used to refinance in part the tranche B-2 term loans outstanding under the original first lien credit facility. The proceeds of the tranche B term loans were used to (i) refinance the remaining tranche B-2 term loans outstanding under the original first lien credit facility, (ii) refinance other amounts outstanding under the original first lien credit facility and (iii) pay fees and expenses related thereto. The revolving credit facility replaced the revolving credit facility under the original first lien credit facility.
	The tranche A term loans and the revolving credit facility will mature on July 9, 2019. The tranche B term loans will mature on July 9, 2017. Loans under the revolving credit facility are expected to be used for working capital and other general corporate purposes.
	The Amended and Restated Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company and its subsidiaries, including, among other things, restrictions on indebtedness, liens, investments, mergers, dispositions, prepayment of other indebtedness, and dividends and other distributions. The Amended and Restated Credit Agreement also contains financial covenants that require the Company to maintain a minimum consolidated interest coverage ratio of at least 3.50 to 1.00, beginning with the fiscal quarter ending September 30, 2014, and a maximum total leverage ratio, currently at 5.00 to 1.00.

	Basis of Presentation
	The accompanying unaudited consolidated financial statements and footnotes thereto of the Company and its wholly owned subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (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. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 with the SEC on March 27, 2014. There have been no changes to the Company’s significant accounting policies described in the prospectus that have had a material impact on our consolidated financial statements and related notes. All intercompany accounts and transactions have been eliminated in consolidation.
	The accompanying unaudited consolidated balance sheets present the current assets and current liabilities directly related to the processing of human resources transactions as WSE-related assets and WSE-related liabilities, respectively. WSE-related assets comprise cash and investments restricted for current workers compensation claim payments, payroll funds collected, accounts receivable, unbilled service revenues, and refundable or prepaid amounts related to the Company-sponsored workers compensation and health plan programs. WSE-related liabilities comprise customer prepayments, wages and payroll taxes accrued and payable, and liabilities related to the Company-sponsored workers compensation and health plan programs resulting from workers compensation case reserves, premium amounts due to providers for enrolled employees, and workers compensation and health reserves that are expected to be disbursed within the next 12 months.
	The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary for fair presentation. The results of the six months ended June 30, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014.
Use of Estimates	'
	Seasonality
	Historically, the Company has experienced its highest monthly addition of WSEs, as well as its highest monthly levels of client attrition, in the month of January, primarily because clients that change their payroll service providers tend to do so at the beginning of a calendar year. In addition, the Company experiences higher levels of client attrition in connection with renewals of the health insurance it provides for its WSEs, in the event that such renewals result in increased premiums that it passes on to its clients. The Company has also historically experienced higher insurance claim volumes in the second and third quarters of a fiscal year than in the first and fourth quarters of a fiscal year, as WSEs typically access their health care providers more often in the second and third quarters of a fiscal year, which has negatively impacted the Company’s insurance costs in these quarters. These historical trends may change, and other seasonal trends may develop that make it more difficult for the Company to manage its business.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. These estimates include, but are not limited to, allowances for accounts receivable, workers compensation related assets and liabilities, health plan assets and liabilities, recoverability of goodwill and other intangible assets, income taxes, stock-based compensation and other contingent liabilities. Such estimates are based on historical experience and on various other assumptions that Company management believes to be reasonable under the circumstances. Actual results could differ from those estimates.

	In June 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-12—Compensation-Stock Compensation, which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. ASU 2014-12 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2015. Early adoption is permitted. The amendments may be applied prospectively to all awards granted or modified after the effective date or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented. The Company does not expect this guidance to have a material effect on its consolidated financial statements. The Company expects to adopt this guidance in 2016.
	In May 2014, the FASB issued ASU 2014-09—Revenue from Contracts with Customers, which will replace most existing revenue recognition guidance under GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard provides a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2016. Early adoption is not permitted. The amendments may be applied retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company expects to adopt this guidance in 2017. The Company has not yet selected a method of adoption and is currently evaluating the effect that the amendments will have on the consolidated financial statements.
	In July 2013, the FASB issued ASU 2013-11—Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, which requires that an unrecognized tax benefit, or portion of an unrecognized tax benefit, be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. If an applicable deferred tax asset is not available or a company does not expect to use the applicable deferred tax asset, the unrecognized tax benefit should be presented as a liability in the financial statements and should not be combined with an unrelated deferred tax asset. ASU 2013-11 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2013. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date, however retrospective application is permitted. The Company adopted this guidance in 2014. The adoption of ASU 2013-11 did not have a material impact on the Company’s consolidated financial statements.

Plan description

'

'

'

'

'

'

'

'

'The fair value of restricted stock units is equal to the fair value of the Company’s common stock on the date of grant. The restricted stock units vest at a rate of 25% at the end of the first year and then pro rata monthly thereafter over the remaining vesting term of three or two years, as applicable.

'

'Options issued to recipients other than nonemployee directors generally vest over four years with a one year cliff and monthly thereafter, and have a maximum contractual term of 10 years.

'

'

'

'

'

'

'

'

'The amended 2009 Plan also provides that the number of shares reserved for issuance under the 2009 Plan will increase on January 1 of each year for a period of up to five years by 4.5% of the total number of shares of capital stock outstanding on December 31 of the preceding calendar year, which will begin on January 1, 2015 and continue through January 1, 2019
