FORWARD LOOKING STATEMENTS

The statements contained herein that are not historical facts are forward-looking statements within the meaning of the federal securities laws (Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act). You can identify such forward-looking statements by the words “anticipates,” “expects,” “intends,” “plans,” “projects,” “believes,” “estimates,” “likely,” “possibly,” “probably,” “could,” “goal,” “opportunity,” “objective,” “target,” “assume,” “outlook,” “guidance,” “predicts,” “appears,” “indicator” and similar expressions. Forward-looking statements involve a number of risks and uncertainties. In the normal course of business, in an effort to help keep our stockholders and the public informed about our operations, from time to time, we may issue such forward-looking statements, either orally or in writing. Generally, these statements relate to business plans or strategies; projected or anticipated benefits or other consequences of such plans or strategies; or projections involving anticipated revenues, earnings, average number of worksite employees (“WSEEs”), benefits and workers’ compensation costs, or other operating results. We base the forward-looking statements on our current expectations, estimates and projections. We caution you that these statements are not guarantees of future performance and involve risks, uncertainties and assumptions that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Therefore, the actual results of the future events described in such forward-looking statements could differ materially from those stated in such forward-looking statements. Among the factors that could cause actual results to differ materially are:
•adverse economic conditions;
•impact of the COVID-19 pandemic, or other future pandemics, including the scope, severity and duration of the pandemic; government responses; regulatory developments; and the related disruptions and economic impact to our business and the small and medium-sized businesses that we serve;
•vulnerability to regional economic factors because of our geographic market concentration;
•failure to comply with covenants under our credit facility;
•our liability for worksite employee payroll, payroll taxes and benefits costs;
•increases in health insurance costs and workers’ compensation rates and underlying claims trends, health care reform, financial solvency of workers’ compensation carriers, other insurers or financial institutions, state unemployment tax rates, liabilities for employee and client actions or payroll-related claims;
•cancellation of client contracts on short notice, or the inability to renew client contracts or attract new clients;
•the ability to secure competitive replacement contracts for health insurance and workers’ compensation insurance at expiration of current contracts;
•regulatory and tax developments and possible adverse application of various federal, state and local regulations;
•failure to manage growth of our operations and the effectiveness of our sales and marketing efforts;
•the impact of the competitive environment and other developments in the human resources services industry, including the PEO industry, on our growth and/or profitability;
•an adverse final judgment or settlement of claims against Insperity;
•disruptions of our information technology systems;
•our liability or damage to our reputation relating to disclosure of sensitive or private information as a result of data theft, cyberattacks or security vulnerabilities;
•failure of third-party providers, data centers or cloud service providers; and
•our ability to integrate or realize expected returns on our acquisitions.
These factors are discussed in further detail in our Annual Report on Form 10-K for the year ended December 31, 2020 under “Item 1A. Risk Factors” in Part I and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, and elsewhere in this report. Any of these factors, or a combination of

such factors, could materially affect the results of our operations and whether forward-looking statements we make ultimately prove to be accurate.
Any forward-looking statements are made only as of the date hereof and, unless otherwise required by applicable securities laws, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. | Basis of Presentation

Insperity, Inc., a Delaware corporation (“Insperity,” “we,” “our,” and “us”), provides an array of human resources (“HR”) and business solutions designed to help improve business performance. Our most comprehensive HR services offerings are provided through our professional employer organization (“PEO”) services, known as Workforce Optimization® and Workforce Synchronization TM solutions (together, our “PEO HR Outsourcing solutions”), which we provide by entering into a co-employment relationship with our clients. Our PEO HR Outsourcing solutions encompass a broad range of HR functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services, along with our cloud-based human capital management solution, the Insperity Premier TM platform.
In addition to our PEO HR Outsourcing solutions, we offer a comprehensive traditional payroll and human capital management solution, known as Workforce Acceleration TM. We also offer a number of other business performance solutions, including Comprehensive Traditional Payroll and Human Capital Management, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services and Insurance Services, many of which are offered as a cloud-based software solution. These other products or services are offered separately or with our other solutions.
The Consolidated Financial Statements include the accounts of Insperity, Inc. and its wholly owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation.
The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
The accompanying Consolidated Financial Statements should be read in conjunction with our audited Consolidated Financial Statements at and for the year ended December 31, 2020. Our Condensed Consolidated Balance Sheet at December 31, 2020 has been derived from the audited financial statements at that date, but does not include all of the information or footnotes required by GAAP for complete financial statements. Our Condensed Consolidated Balance Sheet at September 30, 2021 and our Consolidated Statements of Operations for the three and nine month periods ended September 30, 2021 and 2020, our Consolidated Statements of Cash Flows for the nine month periods ended September 30, 2021 and 2020 and our Consolidated Statements of Stockholders’ Equity for the three and nine month periods ended September 30, 2021 and 2020, have been prepared by us without audit. In the opinion of management, all adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows have been made, and all such adjustments are of a normal recurring nature.
The results of operations for the interim periods are not necessarily indicative of the operating results for a full year or of future operations.

2. | Accounting Policies

Health Insurance Costs
We provide group health insurance coverage to our WSEEs in our PEO HR Outsourcing solutions through a national network of carriers, including UnitedHealthcare (“United”), UnitedHealthcare of California, Kaiser Permanente, Blue Shield of California, HMSA BlueCross BlueShield of Hawaii, and Tufts, all of which provide fully insured policies or service contracts.
The policy with United provides approximately 87% of our participants’ health insurance coverage. While the policy with United is a fully-insured plan, as a result of certain contractual terms, we have accounted for this plan since its inception using a partially self-funded insurance accounting model. Effective January 1, 2020, under the amended agreement with United, we no longer have financial responsibilities for a participant’s annual claim costs that exceed $1 million. Accordingly, we record the costs of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”), as benefits expense, which is a component of direct costs, in our Consolidated Statements of Operations. The estimated incurred claims are based upon: (1) the level of claims processed during the quarter; (2) estimated completion rates based upon recent claim development patterns under

Insperity | 2021 Third Quarter Form 10-Q | 12

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

the plan; and (3) the number of participants in the plan, including both active and COBRA enrollees. Each reporting period, changes in the estimated ultimate costs resulting from claim trends, plan design and migration, participant demographics and other factors are incorporated into the benefits costs, which requires a significant level of judgment.
Additionally, since the plan’s inception, under the terms of the contract, United establishes cash funding rates 90 days in advance of the beginning of a reporting quarter. If the Plan Costs for a reporting quarter are greater than the premiums paid and owed to United, a deficit in the plan would be incurred and a liability for the excess costs would be accrued in our Condensed Consolidated Balance Sheets. On the other hand, if the Plan Costs for the reporting quarter are less than the premiums paid and owed to United, a surplus in the plan would be incurred and we would record an asset for the excess premiums in our Condensed Consolidated Balance Sheets. The terms of the arrangement require us to maintain an accumulated cash surplus in the plan of $9.0 million, which is reported as long-term prepaid insurance. In addition, United requires a deposit equal to approximately one day of claims funding activity, which was $6.5 million at September 30, 2021, and is included in deposits - health insurance as a long-term asset on our Condensed Consolidated Balance Sheets. As of September 30, 2021, Plan Costs were less than the net premiums paid and owed to United by $15.3 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $6.3 million difference is included in prepaid insurance, a current asset, in our Condensed Consolidated Balance Sheets. The premiums, including the additional quarterly premiums, owed to United at September 30, 2021 were $33.7 million, which is included in accrued health insurance costs, a current liability in our Condensed Consolidated Balance Sheets. Our benefits costs incurred in the first nine months of 2021 included an increase of $4.5 million for changes in estimated run-off related to prior periods. Our benefits costs incurred in the first nine months of 2020 included a reduction of $1.9 million for changes in estimated run-off related to prior periods.
Workers’ Compensation Costs
Our workers’ compensation coverage for our WSEEs in our PEO HR Outsourcing solutions has been provided through an arrangement with the Chubb Group of Insurance Companies or its predecessors (the “Chubb Program”) since 2007. The Chubb Program is fully insured in that Chubb has the responsibility to pay all claims incurred under the policy regardless of whether we satisfy our responsibilities. Under the Chubb Program for claims incurred on or before September 30, 2019, we have financial responsibility to Chubb for the first $1 million layer of claims per occurrence and, for claims over $1 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1 million. Chubb bears the financial responsibility for all claims in excess of these levels. Effective for claims incurred on or after October 1, 2019, we have financial responsibility to Chubb for the first $1.5 million layer of claims per occurrence and, for claims over $1.5 million, up to a maximum aggregate amount of $6 million per policy year for claims that exceed $1.5 million.
Because we bear the financial responsibility for claims up to the levels noted above, such claims, which are the primary component of our workers’ compensation costs, are recorded in the period incurred. Workers’ compensation insurance includes ongoing health care and indemnity coverage whereby claims are paid over numerous years following the date of injury. Accordingly, the accrual of related incurred costs in each reporting period includes estimates, which take into account the ongoing development of claims and therefore requires a significant level of judgment.
We utilize a third-party actuary to estimate our loss development rate, which is primarily based upon the nature of WSEEs’ job responsibilities, the location of WSEEs, the historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. Each reporting period, changes in the actuarial assumptions resulting from changes in actual claims experience and other trends are incorporated into our workers’ compensation claims cost estimates. During the nine months ended September 30, 2021 and 2020, we reduced accrued workers’ compensation costs by $31.4 million and $32.4 million, respectively, for changes in estimated losses related to prior reporting periods. Workers’ compensation cost estimates are discounted to present value at a rate based upon the U.S. Treasury rates that correspond with the weighted average estimated claim payout period (the average discount rate utilized in the 2021 period was 0.5% and in the 2020 period was 0.7%) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations.

Total accrued claims | $ | 239,006 |  |  | $ | 241,512 |

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at September 30, 2021 includes $3.6 million of workers’ compensation administrative fees.
As of September 30, 2021 and 2020, the undiscounted accrued workers’ compensation costs were $254.5 million and $259.4 million, respectively.
At the beginning of each policy period, the workers’ compensation insurance carrier establishes monthly funding requirements comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”). The level of claim funds is primarily based upon anticipated WSEE payroll levels and expected workers’ compensation loss rates, as determined by the insurance carrier. Monies funded into the program for incurred claims expected to be paid within one year are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included in deposits – workers’ compensation, a long-term asset in our Condensed Consolidated Balance Sheets. At September 30, 2021, we had restricted cash of $47.8 million and deposits – workers’ compensation of $208.2 million.
Our estimate of incurred claim costs expected to be paid within one year is included in short-term liabilities, while our estimate of incurred claim costs expected to be paid beyond one year is included in long-term liabilities on our Condensed Consolidated Balance Sheets.
Revenue and Direct Cost Recognition
We enter into contracts with our customers for human resources services based on a stated rate and price in the contract. Our contracts generally establish pricing for a period of 12 months, and are generally cancellable at any time by either party with 30-days’ notice. Our performance obligations are satisfied as services are rendered each month. The term between invoicing and when our performance obligations are satisfied is not significant. Payment terms are typically due concurrently with the invoicing of our PEO services. We do not have significant financing components or significant payment terms.
Our revenue is generally recognized ratably over the payroll period as WSEEs perform their service at the client worksite. Customers are invoiced concurrently with each periodic payroll of its WSEEs. Revenues that have been recognized but unbilled of $564.6 million and $380.8 million at September 30, 2021 and December 31, 2020, respectively, are included in accounts receivable, net on our Condensed Consolidated Balance Sheets.
Pursuant to the “practical expedients” provided under Accounting Standards Update No 2014-09, we expense sales commissions when incurred because the terms of our contracts generally are cancellable by either party with a 30-day notice. These costs are recorded in commissions in our Consolidated Statements of Operations.

4. | Fair Value Measurements

We account for our financial assets in accordance with Accounting Standard Codification 820, Fair Value Measurement. This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The fair value measurement disclosures are grouped into three levels based on valuation factors:
•Level 1 - quoted prices in active markets using identical assets
•Level 2 - significant other observable inputs, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other observable inputs
•Level 3 - significant unobservable inputs

The municipal bond securities valued as Level 2 are primarily pre-refunded municipal bonds that are secured by escrow funds containing U.S. government securities. Our valuation techniques used to measure fair value for these securities during the period consisted primarily of third-party pricing services that utilized actual market data such as trades of comparable bond issues, broker/dealer quotations for the same or similar investments in active markets and other observable inputs.

5. | Long-Term Debt

We have a revolving credit facility (the “Facility”) with borrowing capacity of up to $500 million. The Facility may be further increased to $550 million based on the terms and subject to the conditions set forth in the agreement relating to the Facility (as amended, the “Credit Agreement”). The Facility is available for working capital and general corporate purposes, including acquisitions, stock repurchases and issuances of letters of credit. Our obligations under the Facility are secured by 65% of the stock of our captive insurance subsidiary and are guaranteed by all of our domestic subsidiaries other than certain excluded subsidiaries. At September 30, 2021, our outstanding balance on the Facility was $369.4 million, and we had an outstanding $1.0 million letter of credit issued under the Facility, resulting in an available borrowing capacity of $129.6 million.
The Facility matures on September 13, 2024. Borrowings under the Facility bear interest at an annual rate equal to an alternate base rate or LIBOR, at our option, plus an applicable margin. Depending on our leverage ratio, the applicable margin varies (1) in the case of LIBOR loans, from 1.50% to 2.25% and (2) in the case of alternate base rate loans, from 0.00% to 0.50%. The alternate base rate is the highest of (1) the prime rate most recently published in The Wall Street Journal, (2) the federal funds rate plus 0.50% and (3) the 30-day LIBOR rate plus 2.00%. We also pay an unused commitment fee on the average daily unused portion of the Facility at a rate of 0.25% per year. The average interest rate for the nine month period ended September 30, 2021 was 1.9%. Interest expense and unused commitment fees are recorded in other income (expense). Following early opt-in by us or our lenders or such other time as LIBOR rates have permanently or indefinitely ceased to be published by the regulatory supervisory authority of LIBOR, then LIBOR will be replaced by a rate per annum equal to the secured overnight financing rate published by the Federal Reserve Bank of New York or such other benchmark as determined in accordance with the Credit Agreement.
The Facility contains both affirmative and negative covenants that we believe are customary for arrangements of this nature. Covenants include, but are not limited to, limitations on our ability to incur additional indebtedness, sell material assets, retire, redeem or otherwise reacquire our capital stock, acquire the capital stock or assets of another business, make investments and pay dividends. In addition, the Credit Agreement requires us to comply with financial covenants limiting our total funded debt, minimum interest coverage ratio and maximum leverage ratio. We were in compliance with all financial covenants under the Credit Agreement at September 30, 2021.

6. | Stockholders' Equity

During the first nine months of 2021, we repurchased or withheld an aggregate of 544,132 shares of our common stock, as described below.
Repurchase Program
Our Board of Directors (the “Board”) has authorized a program to repurchase shares of our outstanding common stock (“Repurchase Program”). The purchases may be made from time to time in the open market or directly from stockholders at prevailing market prices based on market conditions and other factors. During the nine months ended September 30, 2021, 253,309 shares were repurchased under the Repurchase Program. As of September 30, 2021, we were authorized to repurchase an additional 874,828 shares under the Repurchase Program.
Withheld Shares
During the nine months ended September 30, 2021, we withheld 290,823 shares to satisfy tax withholding obligations for the vesting of long-term incentive and restricted stock awards.

Dividends
The Board declared quarterly dividends as follows:

(amounts per share) | 2021 |  | 2020
First quarter | $ | 0.40 |  |  | $ | 0.40 |
Second quarter | 0.45 |  |  | 0.40 |
Third quarter | 0.45 |  |  | 0.40 |

During the nine months ended September 30, 2021 and 2020, we paid dividends totaling $50.2 million and $46.5 million, respectively.

7. | Net Income Per Share

We utilize the two-class method to compute net income per share. The two-class method allocates a portion of net income to participating securities, which includes unvested awards of share-based payments with non-forfeitable rights to receive dividends. Net income allocated to unvested share-based payments is excluded from net income allocated to common shares. Any undistributed losses resulting from dividends exceeding net income are not allocated to participating securities. Basic net income per share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income allocated to common shares by the weighted average number of common shares outstanding during the period, plus the dilutive effect of time-vested and performance-based restricted stock units (“RSUs”).
The following table summarizes the net income allocated to common shares and the basic and diluted shares used in the net income per share computations:

| Three Months Ended September 30, |  | Nine Months Ended September 30,
(in thousands) | 2021 | 2020 |  | 2021 | 2020
Net income | $ | 27,296 |  | $ | 20,009 |  |  | $ | 114,372 |  | $ | 133,952 |
Less distributed and undistributed earnings allocated to participating securities | (39) |  | (104) |  |  | (219) |  | (792) |
Net income allocated to common shares | $ | 27,257 |  | $ | 19,905 |  |  | $ | 114,153 |  | $ | 133,160 |
Weighted average common shares outstanding | 38,524 |  | 38,507 |  |  | 38,445 |  | 38,625 |

8. | Commitments and Contingencies

Securities Class Action Lawsuit
In July 2020, a federal securities class action was filed against us and certain of our officers in the United States District Court for the Southern District of New York. The name of the case is Building Trades Pension Fund of Western Pennsylvania v. Insperity, Inc. et al., Case No. 1:20-cv-05635-NRB. On October 23, 2020, the court issued an order appointing Oakland County Employees’ Retirement System and Oakland County Voluntary Employees’ Beneficiary Association Trust as lead plaintiff (“Lead Plaintiff”). On December 22, 2020, the Lead Plaintiff filed its consolidated complaint alleging that we made materially false and misleading statements regarding our business and operations in violation of the federal securities laws and seeking unspecified damages, attorneys’ fees, costs, equitable/injunctive relief, and such other relief that may be deemed proper. On April 26, 2021, the defendants moved to dismiss the consolidated complaint with prejudice. The Lead Plaintiff filed its opposition to the motion to dismiss on June 10, 2021, and the defendants filed their reply in support of the motion to dismiss on July 12, 2021. We believe the allegations in the action are without merit, and we intend to vigorously defend this litigation. As a result of uncertainty regarding the outcome of this matter, no provision has been made in the accompanying Consolidated Financial Statements.
Other Litigation
We are a defendant in various other lawsuits and claims arising in the normal course of business. Management believes it has valid defenses in these cases and is defending them vigorously. While the results of litigation cannot be predicted with certainty, management believes the final outcome of such litigation will not have a material adverse effect on our financial position or results of operations.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020, as well as our Consolidated Financial Statements and notes thereto included in this Quarterly Report on Form 10-Q.
Executive Summary
Overview
Insperity, Inc. (“Insperity,” “we,” “our,” and “us”) provides an array of human resources (“HR”) and business solutions designed to help improve business performance. Our most comprehensive HR services offerings are provided through our professional employer organization (“PEO”) services, known as Workforce Optimization® and Workforce Synchronization TM solutions (together, our “PEO HR Outsourcing solutions”), which we provide by entering into a co-employment relationship with our clients. Our PEO HR Outsourcing solutions encompass a broad range of HR functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services, along with our cloud-based human capital management solution, the Insperity Premier TM platform.
COVID-19 Pandemic
The effects of the COVID-19 pandemic, including actions taken by businesses and governments, have resulted in significant changes in U.S. economic activity. As the duration of the pandemic and such economic impacts remain uncertain, we have planned for a range of scenarios and have modified certain business and workforce practices. To conform to government restrictions and best practices, we have taken steps designed to keep our staff safe while continuing to serve clients, including implementing flexible remote working arrangements for our employees and providing extra safety measures at corporate facilities. To serve our clients, we have instituted a number of service offerings and developed COVID-19 resources to assist clients with obtaining government provided tax credits, tax deferrals, loans and loan forgiveness and to provide guidance to assist clients with addressing the challenges faced by employers as a result of the pandemic. These service offerings and guidance to assist clients during the pandemic included additional benefits support, remote workforce transition, monitoring and educating on regulatory changes, including vaccine mandates; return to the workplace and workplace safety.
In the third quarter of 2021 (“Q3 2021”), the average number of WSEEs paid per month increased 11.1% year-over-year as the Q3 2021 increase in WSEEs paid at existing clients combined with WSEEs paid from new sales exceeded the third quarter of 2020 (“Q3 2020”) levels. We expect the average number of paid WSEEs per month to increase between 11.0% and 12.0% in the fourth quarter of 2021 as compared to the fourth quarter of 2020, which, if achieved, would equate to the average number of paid WSEEs per month growing 3.1% to 4.1% sequentially from the third quarter of 2021.
We experienced a 10.3% increase in the year-over-year benefits costs per covered employee during the first nine months of 2021 as compared to the first nine months of 2020, which had substantially lower costs primarily due to the significant decrease in benefits utilization that we experienced during the second quarter of 2020. During the second quarter of 2020, we experienced a 10.7% decrease in benefits costs per covered employee due primarily to lower utilization of medical services by plan participants as a result of the COVID-19 pandemic, including in response to COVID-19 governmental requirements or guidance related to the deferral of non-essential medical procedures and shelter-in-place and similar orders. During the remainder of 2021 and possibly beyond 2021, benefits costs are expected to continue to be affected by the dynamics of the pandemic, including the impact on healthcare utilization and incremental COVID-19 testing, vaccine and treatment costs. This may result in a higher level of healthcare claims costs than our historical claim cost trends. While we have experienced a reduced frequency in workers’ compensation claims during the COVID-19 pandemic, the COVID-19 pandemic has not had a material impact on our workers’ compensation cost estimate; however, the ultimate impact of COVID-19 on our workers’ compensation program remains uncertain.
The extent to which our future results are affected by the COVID-19 pandemic will depend on various factors and consequences beyond our control, such as the scope, duration and magnitude of the pandemic, impacts of changes in or variants of the COVID-19 virus, actions by businesses and governments in response to the pandemic, including programs designed to assist small and medium-sized businesses with the economic impact of the pandemic; and the

speed and effectiveness of responses to combat the virus, including the development, availability and acceptance of therapeutics and vaccines. See Part II, Item 1A. “Risk Factors” for additional information.

Results of Operations
Key Operating Metrics
We monitor certain key metrics to measure our performance, including:
•WSEEs
•Adjusted EBITDA
•Adjusted EPS
Our growth in the number of WSEEs paid is affected by three primary sources: new client sales, client retention and the net change in WSEEs paid at existing clients through new hires and layoffs.
•During Q3 2021, WSEEs paid increased 11.1% compared to Q3 2020. The number of WSEEs paid from new client sales and client retention improved compared to Q3 2020 and the net gain (loss) in our client base improved compared to Q3 2020 as clients continue to recover from the effects of the pandemic.
•During the first nine months of 2021 (“YTD 2021”), WSEEs paid increased 5.2% compared to the first nine months of 2020 (“YTD 2020”). The number of WSEEs paid from new client sales improved compared to YTD 2020 and the net gain (loss) in our client base improved compared to YTD 2020 as clients continue to recover from the effects of the pandemic. Client retention remained consistent compared to YTD 2020.

Revenues
Our PEO HR Outsourcing solutions revenues are primarily derived from our gross billings, which are based on (1) the payroll cost of our WSEEs and (2) a monthly markup component .
Our revenues are primarily dependent on the number of clients enrolled, the resulting number of WSEEs paid each period and the number of WSEEs enrolled in our benefit plans. Because our monthly markup is computed in part as a percentage of payroll cost, certain revenues are also affected by the payroll cost of WSEEs, which may fluctuate based on the composition of the WSEE base, inflationary effects on wage levels and differences in the local economies of our markets.

Significant Markets
We believe the middle market sector, which we generally define as those companies with employees ranging from approximately 150 to 5,000 WSEEs, has historically been under-served by the PEO industry. Currently, we have a dedicated sales management, service personnel, and consulting staff who concentrate solely on the middle market sector. Our average number of WSEEs per month in our middle market sector increased 2.4% during YTD 2021 compared to YTD 2020, representing approximately 23.7% and 24.4% of our total average paid WSEEs during YTD 2021 and YTD 2020, respectively.

Insperity | 2021 Third Quarter Form 10-Q | 26

Gross Profit
In determining the pricing of the markup component of our gross billings, we take into consideration our estimates of the costs directly associated with our WSEEs, including payroll taxes, benefits and workers’ compensation costs, plus an acceptable gross profit margin. As a result, our operating results are significantly impacted by our ability to accurately estimate, control and manage our direct costs relative to the revenues derived from the markup component of our gross billings.
Our gross profit per WSEE is primarily determined by our ability to accurately estimate and control direct costs and our ability to incorporate changes in these costs into the gross billings charged to PEO HR Outsourcing solutions clients, which are subject to pricing arrangements that are typically renewed annually. We use gross profit per WSEE per month as our principal measurement of relative performance at the gross profit level.

Third Quarter 2021 Compared to Third Quarter 2020
Gross profit for Q3 2021 increased 7.3% to $198.5 million compared to $185.0 million in Q3 2020. Gross profit per WSEE per month for Q3 2021 decreased $9 to $257 compared to $266 in Q3 2020 due primarily to higher direct costs, offset in part by higher average pricing, as discussed below.
Our pricing objectives attempt to achieve a level of revenue per WSEE that matches or exceeds changes in primary direct costs and operating expenses. Our revenues per WSEE per month increased $115 due to higher average pricing, as well as the non-recurrence of the 2020 FICA deferral elections by clients pursuant to the CARES Act.
The net increase in direct costs between Q3 2021 and Q3 2020 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $6.1 million as discussed below. The $124 per WSEE per month increase in direct costs is due primarily to the direct cost components changes as follows:
Benefits costs
•The cost of group health insurance and related employee benefits increased $27 per WSEE per month and increased 6.0% on a cost per covered employee basis. In Q3 2021, benefits costs continued to reflect the dynamics of the pandemic, including increased utilization of our health plan and COVID-19 related vaccination, testing and treatment costs.
•The percentage of WSEEs covered under our health insurance plans was 66.4% in Q3 2021 compared to 67.9% in Q3 2020.
•Reported results include changes in estimated claims run-off related to prior periods, which was a decrease in costs of $3.7 million, or $5 per WSEE per month, in Q3 2021 compared to a reduction in costs of $7.7 million, or $11 per WSEE per month, in Q3 2020.
Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Health Insurance Costs,” for a discussion of our accounting for health insurance costs.
Workers’ compensation costs
Our continued discipline around our client selection, safety and claims management has allowed for claims within our policy periods to be closed out at amounts below our original cost estimates.
•Workers’ compensation costs increased 20.5%, or $2 per WSEE per month, in Q3 2021 compared to Q3 2020 on an 18.2% increase in non-bonus payroll costs.
•As a percentage of non-bonus payroll cost, workers’ compensation costs in Q3 2021 were 0.30% in both Q3 2021 and Q3 2020.
•We recorded a reduction in workers’ compensation costs of $9.3 million, or 0.15% of non-bonus payroll costs, in Q3 2021 compared to a reduction of $11.4 million, or 0.22% of non-bonus payroll costs, in Q3 2020, primarily as a result of closing out claims at lower than expected costs.
Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Workers’ Compensation Costs,” for a discussion of our accounting for workers’ compensation costs.
Payroll tax costs
•Payroll taxes increased 35.8% on a 22.1% increase in payroll costs, or $96 per WSEE per month, due primarily to the non-recurrence of $40.2 million of the 2020 FICA deferral elections by clients pursuant to the CARES Act.
•Payroll taxes as a percentage of payroll costs increased to 6.0% in Q3 2021 compared to 5.4% Q3 2020, primarily due to the non-recurrence of the 2020 FICA deferral elections by clients pursuant to the CARES Act.

Gross profit for YTD 2021 increased 1.6% to $649.5 million compared to $639.3 million in YTD 2020. Gross profit per WSEE per month for YTD 2021 decreased $10 to $295 compared to $305 in YTD 2020 due primarily to higher direct costs, offset in part by higher average pricing, as discussed below.
Our pricing objectives attempt to achieve a level of revenue per WSEE that matches or exceeds changes in primary direct costs and operating expenses. Our revenues per WSEE per month increased $128 due to higher average pricing as well as the non-recurrence of the 2020 FICA deferral elections pursuant to the CARES Act and the comprehensive service fee credits.
The net increase in direct costs between YTD 2021 and YTD 2020 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $7.4 million as discussed below. The $138 per WSEE per month increase in direct costs is due primarily to the direct cost components changes as follows:
Benefits costs
•The cost of group health insurance and related employee benefits increased $60 per WSEE per month and increased 10.3% on a cost per covered employee basis due primarily to an increase in claims in YTD 2021 compared to YTD 2020, which had lower claims as a result of lower utilization and the deferral of non-essential health care procedures, primarily in the second quarter of 2020, in connection with the COVID-19 pandemic and related government requirements or guidance.
•The percentage of WSEEs covered under our health insurance plans was 67.2% in YTD 2021 compared to 68.0% in YTD 2020.
•Reported results include changes in estimated claims run-off related to prior periods which was an increase in costs of $4.5 million, or $2 per WSEE per month, in YTD 2021 compared to a reduction in costs of $1.9 million, or $1 per WSEE per month, in YTD 2020.
Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Health Insurance Costs,” for a discussion of our accounting for health insurance costs.
Workers’ compensation costs
Our continued discipline around our client selection, safety and claims management contributed to the decrease in our cost per WSEE and, as a result, has allowed for claims within our policy periods to be closed out at amounts below our original cost estimates.
•Workers’ compensation costs increased 0.5%, but decreased $1 on a per WSEE per month basis, in YTD 2021 compared to YTD 2020.
•As a percentage of non-bonus payroll cost, workers’ compensation costs in YTD 2021 were 0.29% compared to 0.33% in YTD 2020.
•We recorded a reduction in workers’ compensation costs of $31.4 million, or 0.18% of non-bonus payroll costs, in YTD 2021 compared to a reduction of $32.4 million, or 0.21% of non-bonus payroll costs, in YTD 2020, primarily as a result of closing out claims at lower than expected costs.
Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Workers’ Compensation Costs,” for a discussion of our accounting for workers’ compensation costs.
Payroll tax costs
•Payroll taxes increased 21.0% on a 16.8% increase in payroll costs, or $79 per WSEE per month, due primarily to the non-recurrence of $85.0 million of client FICA deferral elections pursuant to the CARES Act in YTD 2020, partially offset by the YTD 2021 collection of $16.8 million in federal payroll tax refunds related to prior years.
•Payroll taxes as a percentage of payroll costs increased to 6.7% in YTD 2021 compared to 6.4% in YTD 2020.

Income Tax Expense

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2021 | 2020 |  | 2021 | 2020
Effective income tax rate | 28.0% | 26.3% |  | 26.4% | 26.8%

For the nine months ended September 30, 2021, our provision for income taxes differed from the U.S. statutory rate primarily due to state income taxes, non-deductible expenses and vesting of restricted and long-term incentive stock awards. During the first nine months of 2021 and 2020, we recognized an income tax benefit of $2.2 million and $2.0 million, respectively, related to the vesting of short-term, long-term incentive, and restricted stock awards.
Non-GAAP Financial Measures
Non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used to their most directly comparable GAAP financial measures as provided in the tables below.

Non-GAAP Measure | Definition | Benefit of Non-GAAP Measure
Non-bonus payroll cost | Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our WSEEs. Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ compensation costs under the current program. | Our management refers to non-bonus payroll cost in analyzing, reporting and forecasting our workers’ compensation costs. We include these non-GAAP financial measures because we believe they are useful to investors in allowing for greater transparency related to the costs incurred under our current workers’ compensation program.
Adjusted cash, cash equivalents and marketable securities | Excludes funds associated with: • federal and state income tax withholdings, • employment taxes, • other payroll deductions, and • client prepayments. | We believe that the exclusion of the identified items helps us reflect the fundamentals of our underlying business model and analyze results against our expectations, against prior periods, and to plan for future periods by focusing on our underlying operations. We believe that the adjusted results provide relevant and useful information for investors because they allow investors to view performance in a manner similar to the method used by management and improves their ability to understand and assess our operating performance. Adjusted EBITDA is used by our lenders to assess our leverage and ability to make interest payments.
EBITDA | Represents net income computed in accordance with GAAP, plus: • interest expense, • income tax expense, and • depreciation and amortization expense.
Adjusted EBITDA | Represents EBITDA plus: • non-cash stock-based compensation.
Adjusted net income | Represents net income computed in accordance with GAAP, excluding: • non-cash stock-based compensation.
Adjusted EPS | Represents diluted net income per share computed in accordance with GAAP, excluding: • non-cash stock-based compensation.

Liquidity and Capital Resources
We periodically evaluate our liquidity requirements, capital needs and availability of resources in view of, among other things, our expansion plans, stock repurchases, potential acquisitions, debt service requirements and other operating cash needs. To meet short-term liquidity requirements, which are primarily the payment of direct costs and operating expenses, we rely primarily on cash from operations. Longer-term projects, large stock repurchases or significant acquisitions may be financed with public or private debt or equity. We have a $500 million revolving credit facility (“Facility”) with a syndicate of financial institutions. The Facility is available for working capital and general corporate purposes, including acquisitions and stock repurchases. We have in the past sought, and may in the future seek, to raise additional capital or take other steps to increase or manage our liquidity and capital resources.
We had $500.6 million in cash, cash equivalents and marketable securities at September 30, 2021, of which approximately $198.4 million was payable in early October 2021 for withheld federal and state income taxes, employment taxes and other payroll deductions, and approximately $74.6 million represented client prepayments that were payable in October 2021. At September 30, 2021, we had working capital of $202.3 million compared to $172.3 million at December 31, 2020. We currently believe that our cash on hand, marketable securities, cash flows from operations and availability under the Facility will be adequate to meet our liquidity requirements for the remainder of 2021. We intend to rely on these same sources, as well as public and private debt or equity financing, to meet our longer-term liquidity and capital needs, which we continually monitor in light of our strategic goals and the significant uncertainty created by the COVID-19 pandemic.
As of September 30, 2021, we had an outstanding letter of credit and borrowings totaling $370.4 million under the Facility. Please read Note 5 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cash Flows from Operating Activities
Net cash provided by operating activities in the first nine months of 2021 was $54.8 million. Our primary source of cash from operations is the comprehensive service fee and payroll funding we collect from our clients. Our cash and cash equivalents, and thus our reported cash flows from operating activities, are significantly impacted by various external and internal factors, which are reflected in part by the changes in our balance sheet accounts. These include the following:
•Timing of client payments / payroll taxes – We typically collect our comprehensive service fee, along with the client’s payroll funding, from clients no later than the same day as the payment of WSEE payrolls and associated payroll taxes. Therefore, the last business day of a reporting period has a substantial impact on our reporting of operating cash flows. For example, many WSEEs are paid on Fridays; therefore, operating cash flows decrease in the reporting periods that end on a Friday or a Monday. In the period ended September 30, 2021, the last business day of the reporting period was a Thursday, client prepayments were $74.6 million and employment taxes and other deductions were $198.4 million. In the period ended September 30, 2020, the last business day of the reporting period was a Wednesday, client prepayments were $46.5 million and employment taxes and other deductions were $147.1 million.
•Medical plan funding – Our health care contract with United establishes participant cash funding rates 90 days in advance of the beginning of a reporting quarter. Therefore, changes in the participation level of the United plan have a direct impact on our operating cash flows. In addition, changes to the funding rates, which are solely determined by United based primarily upon recent claim history and anticipated cost trends, also have a significant impact on our operating cash flows. As of September 30, 2021, premiums owed and cash funded to United have exceeded the costs of the United plan, resulting in a $15.3 million surplus, $6.3 million of which is reflected as a current asset, and $9.0 million of which is reflected as a long-term asset on our Condensed Consolidated Balance Sheets. The premiums, including an additional quarterly premium, owed to United at September 30, 2021, were $33.7 million, which is included in accrued health insurance costs, a current liability, on our Condensed Consolidated Balance Sheets.
•Operating results – Our net income has a significant impact on our operating cash flows. Our adjusted net income decreased 13.0% to $140.9 million in the first nine months ended September 30, 2021, compared to $161.9 million in the first nine months ended September 30, 2020. Please read “Results of Operations – First Nine Months 2021 Compared to First Nine Months 2020.”
Cash Flows from Investing Activities
Net cash flows used in investing activities were $22.4 million for the nine months ended September 30, 2021, primarily due to property and equipment purchases of $23.6 million.
Cash Flows from Financing Activities
Net cash flows used in financing activities were $95.2 million for the nine months ended September 30, 2021. We paid $50.2 million in dividends and repurchased or withheld $49.8 million in stock.

Insperity | 2021 Third Quarter Form 10-Q | 35

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK AND CONTROLS AND PROCEDURES

Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are primarily exposed to market risks from fluctuations in interest rates and the effects of those fluctuations on the market values of our cash equivalent short-term investments, our available-for-sale marketable securities and our borrowings under our Facility, which bears interest at a variable market rate. As of September 30, 2021, we had outstanding letters of credit and borrowings totaling $370.4 million under the Facility. Please read Note 5 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information.
The cash equivalent short-term investments consist primarily of overnight investments, which are not significantly exposed to interest rate risk, except to the extent that changes in interest rates will ultimately affect the amount of interest income earned on these investments. Our available-for-sale marketable securities are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates.
We attempt to limit our exposure to interest rate risk primarily through diversification and low investment turnover. Our investment policy is designed to maximize after-tax interest income while preserving our principal investment. As a result, our marketable securities consist of tax-exempt short term and intermediate term debt securities, which are primarily U.S. Government Securities.
Item 4. Controls and Procedures
In accordance with Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2021.
There has been no change in our internal controls over financial reporting that occurred during the three months ended September 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.
