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 SynchronizationTM solutions (together, our “PEO HR Outsourcing solutions”), which 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 PremierTM platform.

In addition to our PEO HR Outsourcing solutions, we also offer a comprehensive traditional payroll and human capital management solution, known as Workforce Acceleration. We also offer a number of other business performance solutions, including Time and Attendance, Performance Management, Organizational Planning, Recruiting Services, Employment Screening, Expense Management Services, 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, 2019. Our Condensed Consolidated Balance Sheet at December 31, 2019 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, 2020 and our Consolidated Statements of Operations for the three and nine month periods ended September 30, 2020 and 2019, our Consolidated Statements of Cash Flows for the nine month periods ended September 30, 2020 and 2019 and our Consolidated Statements of Stockholders’ Equity for the nine month periods ended September 30, 2020 and 2019, have been prepared by us without audit. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows, have been made.

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 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 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

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, 2020, and is included in deposits - health insurance as a long-term asset on our Condensed Consolidated Balance Sheets. As of September 30, 2020, Plan Costs were less than the net premiums paid and owed to United by $32.8 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $23.8 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, 2020 were $38.3 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 2020 included a reduction of $1.9 million for changes in estimated run-off related to prior periods. Our benefits costs incurred in the first nine months of 2019 included a charge of $2.9 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, 2020 and 2019, we reduced accrued workers’ compensation costs by $32.4 million and $26.0 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 2020 period was 0.7% and in the 2019 period was 2.0%) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations.

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at September 30, 2020 includes $2.7 million of workers’ compensation administrative fees.

As of September 30, 2020 and 2019, the undiscounted accrued workers’ compensation costs were $259.4 million and $255.3 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. During the first nine months of 2020 and 2019, we received $24.8 million and $16.7 million, respectively, for the return of excess claim funds related to the workers’ compensation program, which resulted in a decrease to deposits – workers’ compensation. At September 30, 2020, we had restricted cash of $45.3 million and deposits – workers’ compensation of $181.6 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 have a term of 12 months, but are 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 $520.9 million and $448.1 million at September 30, 2020 and December 31, 2019, respectively, are included in accounts receivable, net on our Condensed Consolidated Balance Sheets.

Pursuant to the “practical expedients” provided under Accounting Standards Update (“ASU”) 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.

Recently Adopted Accounting Standards

We adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) effective January 1, 2020 with no material impact. Under this standard, we estimate our reserves using information about past events, current conditions and risk characteristics of our customer when assessing risk associated with the collectability of accounts receivables, including unbilled accounts receivables. We require clients to pay invoices for service fees not later than the same day as the applicable payroll date. As such, we generally do not require collateral. As of September 30, 2020, allowance for bad debts was immaterial.

3. Cash, Cash Equivalents and Marketable Securities

The following table summarizes our cash and investments in cash equivalents and marketable securities held by investment managers and overnight investments:

Our cash and overnight holdings fluctuate based on the timing of clients’ payroll processing cycles. Our cash, cash equivalents and marketable securities at September 30, 2020 and December 31, 2019 included $147.1 million and $234.6 million, respectively, of funds associated with federal and state income tax withholdings, employment taxes and other payroll deductions, as well as $46.5 million and $59.6 million, respectively, in client prepayments.

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

Insperity | 2020 Third Quarter Form 10-Q 13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

•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

Fair Value of Instruments Measured and Recognized at Fair Value

The following table summarizes the levels of fair value measurements of our financial assets:

	September 30, 2020						December 31, 2019
(in thousands)	Total		Level 1		Level 2		Total		Level 1		Level 2
Money market funds	$	353,819	$	353,819	$	—	$	363,075	$	363,075	$	—
U.S. Treasury bills	10,411		10,411		—		34,728		34,728		—

Total	$	387,813	$	364,230	$	23,583	$	397,803	$	397,803	$	—

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.

The following is a summary of our available-for-sale marketable securities:

(in thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value

Fair Value of Other Financial Instruments

The carrying amounts of cash, cash equivalents, restricted cash, accounts receivable, deposits and accounts payable approximate their fair values due to the short-term maturities of these instruments.

As of September 30, 2020, the carrying value of borrowings under our revolving credit facility approximates fair value and was classified as Level 2 in the fair value hierarchy. Please read Note 5, “Long-Term Debt,” for additional information.

Insperity | 2020 Third Quarter Form 10-Q 14

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

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 (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. At September 30, 2020, 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, 2020 was 2.52%. Interest expense and unused commitment fees are recorded in other income (expense). Upon the discontinuation of LIBOR, the Facility provides that we and the agent will negotiate in good faith to amend the agreement to address such discontinuation and to place the parties in substantially the same economic position.

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, 2020.

6. Stockholders' Equity

During the first nine months of 2020, we repurchased or withheld an aggregate of 1,336,884 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 are to 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, 2020, 1,186,000 shares were repurchased under the Repurchase Program. As of September 30, 2020, we were authorized to repurchase an additional 227,833 shares under the Repurchase Program.

Withheld Shares

During the nine months ended September 30, 2020, we withheld 150,884 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)	2020		2019
First quarter	$	0.40	$	0.30
Second quarter	0.40		0.30
Third quarter	0.40		0.30

Insperity | 2020 Third Quarter Form 10-Q 15

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

During the nine months ended September 30, 2020 and 2019, we paid dividends totaling $46.5 million and $36.8 million, respectively.

Rights Plan

On May 21, 2020, the Board declared a dividend of one right (“Right”) for each outstanding share of common stock to common stockholders of record at the close of business on June 1, 2020 (the “Rights Plan”). Each Right, if and when it becomes exercisable, entitles the registered holder to purchase from us one unit consisting of one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share. Initially, the Rights are attached to all outstanding shares of our common stock. The Rights are not currently exercisable and the Rights Plan will expire at the close of business on May 20, 2021, unless the Rights are earlier redeemed or exchanged by us.

7. Incentive Plans

The Insperity, Inc. 2001 Incentive Plan, as amended, and the 2012 Incentive Plan, as amended (collectively, the “Incentive Plans”) provide for options and other stock-based awards that have been and may be granted to our eligible employees and non-employee directors. The 2012 Incentive Plan is currently the only plan under which new stock-based awards may be granted. Beginning with stock-based awards granted in 2020, employees who attain a minimum of age 62 and have provided 15 years or more of continuous service may continue to vest in awards following a qualifying retirement as defined under the 2012 Incentive Plan, as though he or she were still an employee, provided the grant date of the award is six months or more before the employees last day of employment. For a termination following a qualifying retirement, time-vested awards will continue to vest in the normal course. For a termination following a qualifying retirement, performance-based awards with completed or in-process performance periods are adjusted for achievement of the performance criteria, prorated through the date of termination and paid in the normal course, while performance-based awards for performance periods that have not started are forfeited. Stock-based compensation expense related to time-vested and performance-based awards is accelerated for employees who meet the requirements for continued vesting.

8. 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 outstanding stock options.

9. Commitments and Contingencies

Worksite Employee 401(k) Retirement Plan Class Action Litigation

In December 2015, a class action lawsuit was filed against us and a third-party who served as the discretionary trustee (the “Co-Defendant”) of the Insperity 401(k) retirement plan that is available to eligible worksite employees (the “Plan”) in the United States District Court for the Northern District of Georgia, Atlanta Division, on behalf of Plan participants. The suit generally alleges the third-party discretionary trustee of the Plan and Insperity breached their fiduciary duties to plan participants by selecting an Insperity subsidiary to serve as the recordkeeper for the Plan, by causing participants in the Plan to pay excessive recordkeeping fees to the Insperity subsidiary, by failing to monitor other fiduciaries, and by making imprudent investment choices. The court certified a class defined as “all participants and beneficiaries of the Insperity 401(k) Plan from December 22, 2009 through September 30, 2017.” The court dismissed the breach of fiduciary duty claims relating to the selection of an Insperity subsidiary to serve as the recordkeeper of the Plan. On March 28, 2019, the court partially granted Insperity’s motion for summary judgment, resulting in the dismissal of the claims concerning allegations of excessive recordkeeping fees. The court denied the plaintiffs’ request for a jury trial and set a bench trial, which was held from March 2, 2020 to March 13, 2020. At trial, the plaintiffs alleged damages up to approximately $146 million against all defendants. All parties filed proposed findings of fact and conclusions of law on June 15, 2020. On September 18, 2020, the plaintiffs and Co-Defendant informed the court that they reached an agreement in principle to settle the entire case, including a full and final release of all claims against Insperity. Insperity did not participate in the settlement discussions and will make no financial contribution to the settlement. In connection with the settlement, the plaintiffs and Co-Defendant filed a motion to extend the class period to March 31, 2019, which the court granted. The court has also granted preliminary approval of the settlement and has set the final approval hearing on March 5, 2021. As a result of the uncertainty regarding the outcome of this matter and the subsequent settlement agreement that, if approved by the court, will end the case with no financial contribution from Insperity, no provision has been made in the accompanying Consolidated Financial Statements.

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. The complaint alleges that we made materially false and misleading statements regarding our business and operations in violation of the federal securities laws and seeks unspecified damages, the payment of reasonable attorneys’ fees, expert fees and other costs, and such other relief that may be deemed proper. 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.

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.

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, 2019, 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 SynchronizationTM solutions (together, our “PEO HR Outsourcing solutions”), which 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 PremierTM platform.

COVID-19 Pandemic

The effects of the COVID-19 pandemic, including actions taken by businesses and governments, have resulted in a significant reduction 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 remote working for all non-essential 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, return to workforce and workplace safety.

The COVID-19 pandemic did not have a significant impact to our first quarter 2020 financial results due to the increased spread of, and related government and business responses to, the COVID-19 pandemic not occurring until late in the quarter. However, towards the end of the first quarter, clients began layoffs and temporary leaves of absence of worksite employees (“WSEEs”), and this trend continued into the second quarter and resulted in a 1.8% decline in year-over-year average number of paid WSEEs per month in the second quarter. In the third quarter of 2020, the number of WSEEs returning to work as well as new hires exceeded layoffs, resulting in a 1.7% sequential increase and a 3.8% year-over-year decline in the average number of paid WSEEs per month. We expect the average number of paid WSEEs per month to decline between 2.1% and 3.0% in the fourth quarter of 2020 as compared to the fourth quarter of 2019, which equates to the average number of paid worksite employees per month growing 2% to 3% sequentially from the third quarter of 2020. We expect overall reduced employment levels to have a negative impact on our financial results for at least the remainder of 2020 as compared to 2019.

We experienced a 10.7% decrease in the year-over-year benefits costs per covered employee during the second quarter of 2020 and a 1.1% increase in the year-over-year benefits costs per covered employee during the third quarter of 2020. The third quarter 2020 increase in benefits costs per covered employee over the preceding second quarter of 2020 was due primarily to an increase in non-essential claims as a result of higher utilization and fewer deferrals or cancellations associated with the COVID-19 pandemic. We currently expect to experience higher costs related to COVID-19 and certain non-essential elective healthcare procedures during the remainder of 2020 and possibly into 2021 that had been deferred in response to COVID-19 governmental requirements or guidance related to shelter in place and similar orders. As a result, we expect that our healthcare claim costs will not be reflective of our historical quarterly claim cost trends. In addition, 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. As the impact of the COVID-19 pandemic emerges, such impact, if any, on our workers’ compensation program will be reflected in future reporting periods.

Insperity | 2020 Third Quarter Form 10-Q 19

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

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, 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 and availability of therapeutics and vaccines. See Part II, Item 1A. “Risk Factors” for additional information.

Key Operating Metrics

We monitor certain key metrics to measure our performance, including:

•WSEEs

Insperity | 2020 Third Quarter Form 10-Q 21

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

•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 existing clients through WSEE new hires and layoffs.

•During the third quarter of 2020 (“Q3 2020”), WSEEs paid declined 3.8% compared to the third quarter of 2019 (“Q3 2019”). The net gain (loss) in our client base improved over Q3 2019. In addition, the number of WSEEs paid from new client sales was 92% of Q3 2019 paid from new client sales and client retention averaged 99% in 2020 and 2019.

•During the first nine months of 2020 (“YTD 2020”), WSEEs paid declined 0.1% compared to the first nine months of 2019 (“YTD 2019”). The number of WSEEs paid from new client sales was 96% of YTD 2019. While the net gain (loss) in our client base declined compared to YTD 2019, due primarily to layoffs and furloughs of WSEEs by our clients resulting from the effect of the on-going COVID-19 pandemic, we have seen certain clients make significant hiring of worksite employees while other clients have experienced significant layoffs. Average client retention declined slightly compared to YTD 2019.

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 markup computed as a percentage of the payroll cost.

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 total markup is computed 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.

(in thousands)

Third Quarter 2020 Compared to Third Quarter 2019

Our revenues for Q3 2020 were $1.0 billion, a decrease of 3.4%, primarily due to the following:

•Average WSEEs paid decreased 3.8%.

•Revenues per WSEE per month increased 0.4%, or $6, primarily due to higher average pricing partially offset by $40.2 million in FICA deferral elections by clients and credits pursuant to the CARES Act and the Families First Coronavirus Response Act, which also reduced our direct costs and therefore has no net effect on our gross profit.

First Nine Months 2020 Compared to First Nine Months 2019

Our revenues for YTD 2020 were $3.2 billion, a decrease of 0.3%, primarily due to the following:

•Average WSEEs paid decreased 0.1%.

•Revenues per WSEE per month decreased 0.1%, or $2, primarily due to higher average pricing, which was partially offset by $85.0 million in FICA deferral elections by clients and credits pursuant to the CARES Act and the Families First Coronavirus Response Act, which also reduced our direct costs and therefore has no net effect on our gross profit. In addition, during the second quarter of 2020, we accrued $11.6 million of client comprehensive service fee credits applied generally on a WSEE basis across our active client base to assist clients in addressing the unprecedented economic impact of the COVID-19 pandemic.

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

Third Quarter 2020 Compared to Third Quarter 2019

Gross profit for Q3 2020 increased 8.5% to $185.0 million compared to $170.5 million in Q3 2019. Gross profit per WSEE per month for Q3 2020 increased $30 to $266 compared to $236 in Q3 2019 due primarily to the relative changes in higher pricing and lower direct costs 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 and direct costs per WSEE per month increased $6 and decreased $24, respectively, due to higher average pricing, which was partially offset by client FICA deferral elections pursuant to the CARES Act in Q3 2020 and changes in the primary direct cost components, respectively.

The net decrease in costs between Q3 2020 and Q3 2019 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $18.6 million as discussed below. The primary direct cost components changed as follows:

Benefits costs

Insperity | 2020 Third Quarter Form 10-Q 26

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

•The cost of group health insurance and related employee benefits increased $27 per WSEE per month and increased 1.1% on a cost per covered employee basis.

•The percentage of WSEEs covered under our health insurance plans was 67.9% in Q3 2020 compared to 66.0% in Q3 2019.

•Reported results include changes in estimated claims run-off related to prior periods, which was a decrease in costs of $7.7 million, or $11 per WSEE per month, in Q3 2020 compared to an increase in costs of $7.0 million, or $10 per WSEE per month, in Q3 2019.

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 decreased 30.8%, or $9 per WSEE per month, in Q3 2020 compared to Q3 2019.

•As a percentage of non-bonus payroll cost, workers’ compensation costs in Q3 2020 were 0.30% compared to 0.43% in Q3 2019.

•We recorded a reduction in workers’ compensation costs of $11.4 million, or 0.22% of non-bonus payroll costs, in Q3 2020 compared to a reduction of $7.5 million, or 0.15% of non-bonus payroll costs, in Q3 2019, 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 decreased 12.7% on an 0.8% increase in payroll costs, or $44 per WSEE per month, primarily due to $40.2 million of FICA deferral elections by clients pursuant to the CARES Act. In addition, Internal Revenue Service tax reporting changes in 2020 eliminated PEO reporting of payroll taxes for self-employed owners.

•Payroll taxes as a percentage of payroll costs decreased to 5.4% in Q3 2020 compared to 6.2% in Q3 2019.

First Nine Months 2020 Compared to First Nine Months 2019

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 and direct costs per WSEE per month decreased $2 and $35, respectively, due to higher average pricing, which was offset by client FICA deferral elections pursuant to the CARES Act in YTD 2020 and changes in the primary direct cost components, respectively.

The net decrease in costs between YTD 2020 and YTD 2019 attributable to the changes in cost estimates for benefits and workers’ compensation totaled $11.2 million as discussed below. The primary direct cost components changed as follows:

Benefits costs

•The cost of group health insurance and related employee benefits increased $3 per WSEE per month and decreased 1.5% on a cost per covered employee basis due primarily to a decrease in claims as a result of lower utilization and the deferral of nonessential healthcare procedures, primarily in the second quarter of 2020, in response to COVID-19 government requirements or guidance.

Operating expenses for Q3 2020 increased 15.1% to $156.3 million compared to $135.8 million in Q3 2019. Operating expenses per WSEE per month for Q3 2020 increased 19.7% to $225 compared to $188 in Q3 2019.

•Salaries of corporate and sales staff for Q3 2020 increased 12.8% to $89.4 million, or $19 per WSEE per month, compared to Q3 2019. This increase was primarily due to a 2.3% increase in corporate headcount, including a 6.8% increase in total BPAs in Q3 2020 compared to Q3 2019 and higher incentive compensation accruals in Q3 2020 related to better than expected YTD 2020 operating results compared to lower than expected YTD 2019 operating results in Q3 2019.

•Stock based compensation expense for Q3 2020 increased 220.1% to $20.9 million, or $21 per WSEE per month, compared to Q3 2019. The increase was primarily due to an increase in the number of stock awards anticipated to be earned related to performance-based awards granted under our short-term and long-term incentive plans based on our higher than expected year-to-date operating results in Q3 2020 compared to lower than expected year-to-date results in Q3 2019. In addition, Q3 2020 contains the acceleration of expense for employees who meet the retirement eligibility requirements for continued vesting. Please read Note 7 to the Consolidated Financial Statements, “Incentive Plans,” for additional information.

•Commissions expense for Q3 2020 decreased 3.9% to $7.7 million, but remained flat on a per WSEE per month basis, compared to Q3 2019. The decrease was primarily due to reductions in commissions associated with PEO HR Outsourcing solutions and our other business performance solutions offerings, partially offset by an increase in the amount of sales channel referral fees paid during Q3 2020.

•Advertising expense for Q3 2020 decreased 2.3% to $4.8 million, but remained flat on a per WSEE per month basis, compared to Q3 2019. The decrease was primarily due to decreases in trade shows and events due to COVID-19, partially offset by an increase in internet advertising.

•General and administrative expenses for Q3 2020 decreased 13.9% to $25.6 million, or $4 per WSEE per month, compared to Q3 2019. The decrease was primarily due to reductions in travel and training costs in response to the COVID-19 pandemic, partially offset by increases in technology licensing costs, corporate insurance and rent.

•Depreciation and amortization expense for Q3 2020 increased 6.7% to $7.8 million, or $1 per WSEE per month, compared to Q3 2019. The increase was primarily due to increased capital expenditures related to software development costs and sales office expansions.

•Salaries of corporate and sales staff for YTD 2020 increased 12.3% to $266.6 million, or $14 per WSEE per month, compared to YTD 2019. This increase was primarily due to a 5.0% increase in corporate headcount, including an 10.7% increase in total BPAs in YTD 2020 compared to YTD 2019 and higher incentive compensation accruals in YTD 2020 related to better than expected YTD 2020 operating results compared to lower than expected YTD 2019 operating results in Q3 2019.

•Stock based compensation expense for YTD 2020 increased 83.1% to $38.1 million or $8 per WSEE per month, compared to YTD 2019. The increase was primarily due to an increase in the number of stock awards anticipated to be earned related to performance-based awards granted under our short-term and long-term incentive plans based on our higher than expected YTD 2020 operating results compared to lower than expected YTD 2019 operating results. In addition, YTD 2020 contains the acceleration of expense for employees who meet the retirement eligibility requirements for continued vesting. Please read Note 7 to the Consolidated Financial Statements, “Incentive Plans,” for additional information.

•Commissions expense for YTD 2020 increased 4.1% to $23.7 million, but remained flat on a per WSEE per month basis, compared to YTD 2019. The increase was primarily due to commissions associated with growth in our PEO HR Outsourcing solutions, including an increase in the amount of sales channel referral fees paid during 2020. Additionally, as a result of the extension of our fall campaign into Q1 2020, the bonuses paid to sales managers increased in YTD 2020 compared to YTD 2019.

•Advertising expense for YTD 2020 decreased 12.2% to $15.3 million, or $1 per WSEE per month, compared to YTD 2019. The decrease was primarily due to the cancellation of the 2020 Insperity Invitational and decreases in trade shows and events due to COVID-19, partially offset by an increase in internet advertising.

•General and administrative expenses for YTD 2020 decreased 8.1% to $85.3 million, or $3 per WSEE per month, compared to YTD 2019. The decrease was primarily due to decreased travel and training expenses in response to the COVID-19 pandemic, partially offset by increases in technology licensing costs, corporate insurance and rent.

•Depreciation and amortization expense for YTD 2020 increased 11.5% to $23.3 million, or $1 per WSEE per month, compared to YTD 2019. The increase was primarily due to increased capital expenditures related to software development costs and sales office expansions.

Other Income (Expense)

Other Income (expense) for Q3 2020 was an expense of $1.6 million compared to income of $0.5 million in Q3 2019, and an expense of $4.0 million in YTD 2020 compared to income of $3.2 million in YTD 2019. The net decrease was primarily due to decreased interest income on our marketable securities investments and workers’ compensation deposit and increased interest expense related to the higher outstanding balance on our credit facility. Please read Note 5 to the Consolidated Financial Statements, “Long-Term Debt,” for additional information.

Effective income tax rate	26.3%	26.5%	26.8%	19.4%

For the nine months ended September 30, 2020, 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 2020 and 2019, we recognized an income tax benefit of $2.0 million and $14.5 million, respectively, related to the vesting of 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 repurchase, 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 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 $406.4 million in cash, cash equivalents and marketable securities at September 30, 2020, of which approximately $147.1 million was payable in early October 2020 for withheld federal and state income taxes, employment taxes and other payroll deductions, and approximately $46.5 million represented client prepayments that were payable in October 2020. In March 2020, we borrowed $100.0 million under the Facility, which increased working capital. At September 30, 2020, we had working capital of $207.8 million compared to $105.7 million at December 31, 2019. 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 2020. 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 are carefully monitoring in light of the significant uncertainty created by the COVID-19 pandemic.

Insperity | 2020 Third Quarter Form 10-Q 33

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

As of September 30, 2020, 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.

Cash Flows from Operating Activities

Net cash provided by operating activities in the first nine months of 2020 was $106.6 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 at least one day prior to 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, 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. In the period ended September 30, 2019, the last business day of the reporting period was a Monday, client prepayments were $19.7 million and employment taxes and other deductions were $153.8 million.

•Workers’ compensation plan funding – During YTD 2020, we received $24.8 million for the return of excess claim funds related to the workers’ compensation program, which resulted in an increase in working capital.

•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, 2020, premiums owed and cash funded to United have exceeded the costs of the United plan, resulting in a $32.8 million surplus, $23.8 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, 2020, were $38.3 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 increased 10.4% to $161.9 million in the first nine months ended September 30, 2020, compared to $146.7 million in the first nine months ended September 30, 2019. Please read “Results of Operations – First Nine Months 2020 Compared to First Nine Months 2019.”

Cash Flows from Investing Activities

Net cash flows used in investing activities were $68.4 million for the nine months ended September 30, 2020, primarily due to property and equipment purchases of $68.8 million.

Cash Flows from Financing Activities

Net cash flows used in financing activities were $31.4 million for the nine months ended September 30, 2020. We borrowed $100.0 million under the Facility for general corporate purposes, repurchased or withheld $91.2 million in stock and paid $46.5 million in dividends.

Insperity | 2020 Third Quarter Form 10-Q 34

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, 2020, 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, 2020.

There has been no change in our internal controls over financial reporting that occurred during the three months ended September 30, 2020 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

PART II

Item 1. Legal Proceedings

Please read Note 9 to the Consolidated Financial Statements, “Commitments and Contingencies,” which is incorporated herein by reference.

Item 1A. Risk Factors

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 “expects,” “intends,” “plans,” “projects,” “believes,” “estimates,” “likely,” “possibly,” “probably,” “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, Insperity, Inc., in an effort to help keep our stockholders and the public informed about our operations, may from time to time 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, unit growth, profit per worksite employee, pricing, operating expenses, benefits and workers’ compensation costs, or other aspects of operating results. We base the forward-looking statements on our expectations, estimates and projections at the time such statements are made. These statements are not guarantees of future performance and involve risks and uncertainties 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;

•regulatory and tax developments and possible adverse application of various federal, state and local regulations;

•the ability to secure competitive replacement contracts for health insurance and workers’ compensation insurance at expiration of current contracts;

•cancellation of client contracts on short notice, or the inability to renew client contracts or attract new clients;

•vulnerability to regional economic factors because of our geographic market concentration;

•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;

•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;

•our liability for worksite employee payroll, payroll taxes and benefits costs;

•our liability for disclosure of sensitive or private information;

•our ability to integrate or realize expected returns on our acquisitions;

•failure of our information technology systems;

Insperity | 2020 Third Quarter Form 10-Q 36

OTHER INFORMATION

•an adverse final judgment or settlement of claims against Insperity; and

•disruptions to our business resulting from the actions of certain stockholders.

These factors are discussed in further detail in our Annual Report on Form 10-K for the year ended December 31, 2019 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 in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, under “Item 1A. Risk Factors” 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 SynchronizationTM solutions (together, our “PEO HR Outsourcing solutions”), which 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 PremierTM platform.

In addition to our PEO HR Outsourcing solutions, we also offer a comprehensive traditional payroll and human capital management solution, known as Workforce Acceleration. We also offer a number of other business performance solutions, including Time and Attendance, Performance Management, Organizational Planning, Recruiting Services, Employment Screening, Expense Management Services, 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, 2019. Our Condensed Consolidated Balance Sheet at December 31, 2019 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, 2020 and our Consolidated Statements of Operations for the three and nine month periods ended September 30, 2020 and 2019, our Consolidated Statements of Cash Flows for the nine month periods ended September 30, 2020 and 2019 and our Consolidated Statements of Stockholders’ Equity for the nine month periods ended September 30, 2020 and 2019, have been prepared by us without audit. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary to present fairly the consolidated financial position, results of operations and cash flows, have been made.

The results of operations for the interim periods are not necessarily indicative of the operating results for a full year or of future operations.

Accounting Policies [Abstract]

Accounting Policies

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 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 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, 2020, and is included in deposits - health insurance as a long-term asset on our Condensed Consolidated Balance Sheets. As of September 30, 2020, Plan Costs were less than the net premiums paid and owed to United by $32.8 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $23.8 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, 2020 were $38.3 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 2020 included a reduction of $1.9 million for changes in estimated run-off related to prior periods. Our benefits costs incurred in the first nine months of 2019 included a charge of $2.9 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, 2020 and 2019, we reduced accrued workers’ compensation costs by $32.4 million and $26.0 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 2020 period was 0.7% and in the 2019 period was 2.0%) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations.

The following table provides the activity and balances related to incurred but not paid workers’ compensation claims:

	Nine Months Ended September 30,
(in thousands)	2020		2019
Beginning balance, January 1,	$	242,904	$	229,639
Accrued claims	33,397		44,334
Present value discount, net of accretion	(500)		(3,664)
Paid claims	(34,289)		(34,669)
Ending balance	$	241,512	$	235,640
Current portion of accrued claims	$	45,265	$	45,250
Long-term portion of accrued claims	196,247		190,390
Total accrued claims	$	241,512	$	235,640

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at September 30, 2020 includes $2.7 million of workers’ compensation administrative fees.

As of September 30, 2020 and 2019, the undiscounted accrued workers’ compensation costs were $259.4 million and $255.3 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. During the first nine months of 2020 and 2019, we received $24.8 million and $16.7 million, respectively, for the return of excess claim funds related to the workers’ compensation program, which resulted in a decrease to deposits – workers’ compensation. At September 30, 2020, we had restricted cash of $45.3 million and deposits – workers’ compensation of $181.6 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 have a term of 12 months, but are 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 $520.9 million and $448.1 million at September 30, 2020 and December 31, 2019, respectively, are included in accounts receivable, net on our Condensed Consolidated Balance Sheets.

Pursuant to the “practical expedients” provided under Accounting Standards Update (“ASU”) 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.

Our revenue for our PEO HR Outsourcing solutions by geographic region and for our other products and services offerings are as follows:

Recently Adopted Accounting Standards

We adopted ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) effective January 1, 2020 with no material impact. Under this standard, we estimate our reserves using information about past events, current conditions and risk characteristics of our customer when assessing risk associated with the collectability of accounts receivables, including unbilled accounts receivables. We require clients to pay invoices for service fees not later than the same day as the applicable payroll date. As such, we generally do not require collateral. As of September 30, 2020, allowance for bad debts was immaterial.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

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

Fair Value of Instruments Measured and Recognized at Fair Value

The following table summarizes the levels of fair value measurements of our financial assets:

	September 30, 2020						December 31, 2019
(in thousands)	Total		Level 1		Level 2		Total		Level 1		Level 2
Money market funds	$	353,819	$	353,819	$	—	$	363,075	$	363,075	$	—

Total	$	387,813	$	364,230	$	23,583	$	397,803	$	397,803	$	—

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.

The following is a summary of our available-for-sale marketable securities:

(in thousands)	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Estimated Fair Value

Debt Disclosure [Abstract]

Revolving Credit Facility

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 (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. At September 30, 2020, 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, 2020 was 2.52%. Interest expense and unused commitment fees are recorded in other income (expense). Upon the discontinuation of LIBOR, the Facility provides that we and the agent will negotiate in good faith to amend the agreement to address such discontinuation and to place the parties in substantially the same economic position.

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, 2020.

Stockholders Equity

6. Stockholders' Equity

During the first nine months of 2020, we repurchased or withheld an aggregate of 1,336,884 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 are to 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, 2020, 1,186,000 shares were repurchased under the Repurchase Program. As of September 30, 2020, we were authorized to repurchase an additional 227,833 shares under the Repurchase Program.

Withheld Shares

During the nine months ended September 30, 2020, we withheld 150,884 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)	2020		2019
First quarter	$	0.40	$	0.30
Second quarter	0.40		0.30
Third quarter	0.40		0.30

During the nine months ended September 30, 2020 and 2019, we paid dividends totaling $46.5 million and $36.8 million, respectively.

Rights Plan

On May 21, 2020, the Board declared a dividend of one right (“Right”) for each outstanding share of common stock to common stockholders of record at the close of business on June 1, 2020 (the “Rights Plan”). Each Right, if and when it becomes exercisable, entitles the registered holder to purchase from us one unit consisting of one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $0.01 per share. Initially, the Rights are attached to all outstanding shares of our common stock. The Rights are not currently exercisable and the Rights Plan will expire at the close of business on May 20, 2021, unless the Rights are earlier redeemed or exchanged by us.

7. Incentive Plans

The Insperity, Inc. 2001 Incentive Plan, as amended, and the 2012 Incentive Plan, as amended (collectively, the “Incentive Plans”) provide for options and other stock-based awards that have been and may be granted to our eligible employees and non-employee directors. The 2012 Incentive Plan is currently the only plan under which new stock-based awards may be granted. Beginning with stock-based awards granted in 2020, employees who attain a minimum of age 62 and have provided 15 years or more of continuous service may continue to vest in awards following a qualifying retirement as defined under the 2012 Incentive Plan, as though he or she were still an employee, provided the grant date of the award is six months or more before the employees last day of employment. For a termination following a qualifying retirement, time-vested awards will continue to vest in the normal course. For a termination following a qualifying retirement, performance-based awards with completed or in-process performance periods are adjusted for achievement of the performance criteria, prorated through the date of termination and paid in the normal course, while performance-based awards for performance periods that have not started are forfeited. Stock-based compensation expense related to time-vested and performance-based awards is accelerated for employees who meet the requirements for continued vesting.

Net Income per Share

8. 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 outstanding stock options.

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,

Worksite Employee 401(k) Retirement Plan Class Action Litigation

In December 2015, a class action lawsuit was filed against us and a third-party who served as the discretionary trustee (the “Co-Defendant”) of the Insperity 401(k) retirement plan that is available to eligible worksite employees (the “Plan”) in the United States District Court for the Northern District of Georgia, Atlanta Division, on behalf of Plan participants. The suit generally alleges the third-party discretionary trustee of the Plan and Insperity breached their fiduciary duties to plan participants by selecting an Insperity subsidiary to serve as the recordkeeper for the Plan, by causing participants in the Plan to pay excessive recordkeeping fees to the Insperity subsidiary, by failing to monitor other fiduciaries, and by making imprudent investment choices. The court certified a class defined as “all participants and beneficiaries of the Insperity 401(k) Plan from December 22, 2009 through September 30, 2017.” The court dismissed the breach of fiduciary duty claims relating to the selection of an Insperity subsidiary to serve as the recordkeeper of the Plan. On March 28, 2019, the court partially granted Insperity’s motion for summary judgment, resulting in the dismissal of the claims concerning allegations of excessive recordkeeping fees. The court denied the plaintiffs’ request for a jury trial and set a bench trial, which was held from March 2, 2020 to March 13, 2020. At trial, the plaintiffs alleged damages up to approximately $146 million against all defendants. All parties filed proposed findings of fact and conclusions of law on June 15, 2020. On September 18, 2020, the plaintiffs and Co-Defendant informed the court that they reached an agreement in principle to settle the entire case, including a full and final release of all claims against Insperity. Insperity did not participate in the settlement discussions and will make no financial contribution to the settlement. In connection with the settlement, the plaintiffs and Co-Defendant filed a motion to extend the class period to March 31, 2019, which the court granted. The court has also granted preliminary approval of the settlement and has set the final approval hearing on March 5, 2021. As a result of the uncertainty regarding the outcome of this matter and the subsequent settlement agreement that, if approved by the court, will end the case with no financial contribution from Insperity, no provision has been made in the accompanying Consolidated Financial Statements.

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. The complaint alleges that we made materially false and misleading statements regarding our business and operations in violation of the federal securities laws and seeks unspecified damages, the payment of reasonable attorneys’ fees, expert fees and other costs, and such other relief that may be deemed proper. 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.

Accounting Policies [Abstract]

Health Insurance Costs

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 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 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, 2020, and is included in deposits - health insurance as a long-term asset on our Condensed Consolidated Balance Sheets. As of September 30, 2020, Plan Costs were less than the net premiums paid and owed to United by $32.8 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $23.8 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, 2020 were $38.3 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 2020 included a reduction of $1.9 million for changes in estimated run-off related to prior periods. Our benefits costs incurred in the first nine months of 2019 included a charge of $2.9 million for changes in estimated run-off related to prior periods.

Workers' Compensation Costs

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, 2020 and 2019, we reduced accrued workers’ compensation costs by $32.4 million and $26.0 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 2020 period was 0.7% and in the 2019 period was 2.0%) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations.

The following table provides the activity and balances related to incurred but not paid workers’ compensation claims:

	Nine Months Ended September 30,
(in thousands)	2020		2019
Beginning balance, January 1,	$	242,904	$	229,639

Current portion of accrued claims	$	45,265	$	45,250
Long-term portion of accrued claims	196,247		190,390
Total accrued claims	$	241,512	$	235,640

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at September 30, 2020 includes $2.7 million of workers’ compensation administrative fees.

As of September 30, 2020 and 2019, the undiscounted accrued workers’ compensation costs were $259.4 million and $255.3 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. During the first nine months of 2020 and 2019, we received $24.8 million and $16.7 million, respectively, for the return of excess claim funds related to the workers’ compensation program, which resulted in a decrease to deposits – workers’ compensation. At September 30, 2020, we had restricted cash of $45.3 million and deposits – workers’ compensation of $181.6 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.
