NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. | Basis of Presentation

Insperity, Inc., a Delaware corporation (“Insperity,” “we,” “our,” and “us”), provides an array of human resources (“HR”) and business solutions designed to help improve business performance. Our most comprehensive HR services offerings are provided through our professional employer organization (“PEO”) services, known as Workforce Optimization® and Workforce Synchronization TM solutions (together, our “PEO HR Outsourcing solutions”), which encompass a broad range of HR functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services, along with our cloud-based human capital management solution, the Insperity Premier TM platform.
In addition to our PEO HR Outsourcing solutions, we 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, Retirement Services and Insurance Services, many of which are offered as a cloud-based software solution and are offered separately or with our other solutions.
The Consolidated Financial Statements include the accounts of Insperity 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, 2018. Our Condensed Consolidated Balance Sheet at December 31, 2018 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 June 30, 2019 and our Consolidated Statements of Operations for the three and six month periods ended June 30, 2019 and 2018, our Consolidated Statements of Cash Flows for the six month periods ended June 30, 2019 and 2018 and our Consolidated Statements of Stockholders’ Equity for the three and six month periods ended June 30, 2019 and 2018, 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. Certain prior year amounts have been reclassified to conform to the 2019 presentation.
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. 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.

Insperity | 2019 Second Quarter Form 10-Q | 10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

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 $5.0 million as of June 30, 2019, and is reported as a long-term asset. As of June 30, 2019, Plan Costs were less than the net premiums paid and owed to United by $16.4 million. As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $7.4 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 June 30, 2019 were $15.0 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 six months of 2019 included a charge of $3.5 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, 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.
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 six months ended June 30, 2019 and 2018, we reduced accrued workers’ compensation costs by $19.0 million and $10.9 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 2019 period was 2.3% and in the 2018 period was 2.5%) 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:

Long-term portion of accrued claims | 188,241 |  |  | 174,017 |
Total accrued claims | $ | 231,508 |  |  | $ | 215,844 |

The current portion of accrued workers’ compensation costs on our Condensed Consolidated Balance Sheets at June 30, 2019 includes $3.9 million of workers’ compensation administrative fees.
As of June 30, 2019 and 2018, the undiscounted accrued workers’ compensation costs were $250.9 million and $230.4 million, respectively.
At the beginning of each policy period, the workers’ compensation insurance carrier establishes monthly funding requirements comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”). The level of claim funds is primarily based upon anticipated WSEE payroll levels and expected workers’ compensation loss rates, as determined by the insurance carrier. Monies funded into the program for incurred claims expected to be paid within one year are recorded as restricted cash, a short-term asset, while the remainder of claim funds are included in deposits – workers’ compensation, a long-term asset in our Condensed Consolidated Balance Sheets. During the six months ended June 30, 2019, we funded a collateral deposit of $6.4 million for policy years prior to 2007, which increased deposits. As of June 30, 2019, we had restricted cash of $43.3 million and deposits – workers’ compensation of $187.7 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 $414.6 million and $385.6 million at June 30, 2019 and December 31, 2018, 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 are cancellable by either party with a 30-day notice. These costs are recorded in commissions in our Consolidated Statements of Operations.

4. | Fair Value Measurements

We account for our financial assets in accordance with Accounting Standard Codification 820, Fair Value Measurement. This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The fair value measurement disclosures are grouped into three levels based on valuation factors:

• | Level 1 - quoted prices in active markets using identical assets

• | Level 2 - significant other observable inputs, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other observable inputs

• | Level 3 - significant unobservable inputs

Fair Value of Instruments Measured and Recognized at Fair Value
The following table summarizes the levels of fair value measurements of our financial assets:

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:

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 June 30, 2019, 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.

5. | Long-Term Debt

We have a revolving credit facility (the “Facility”) with borrowing capacity up to $350 million. The Facility may be increased to $400 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

Insperity | 2019 Second Quarter Form 10-Q | 14

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

subsidiaries. At June 30, 2019, our outstanding balance on the Facility was $169.4 million, and we had an outstanding $1.0 million letter of credit issued under the Facility, resulting in an available borrowing capacity of $179.6 million.
The Facility matures on February 6, 2023. Borrowings under the Facility bear interest at 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%. The average interest rate for the period ended June 30, 2019 was 4.00%. Interest expense and unused commitment fees are recorded in other income (expense).
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 June 30, 2019.

6. | Leases

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842), which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms greater than 12 months and also requires disclosures by lessees and lessors about the amount, timing and uncertainty of cash flows arising from leases. Subsequent to the issuance of Topic 842, the FASB clarified the guidance through several ASUs; hereinafter, the collection of lease guidance is referred to as “ASC 842”.
On January 1, 2019 we adopted ASC 842 using the modified retrospective transition method. Results for the reporting period beginning January 1, 2019 are presented under ASC 842, while prior period amounts were not adjusted and continue to be reported in accordance with our historical accounting under ASC 840, Leases. Upon adoption of ASC 842, we increased our total assets and liabilities due to the recording of operating lease ROU assets and operating lease liabilities of approximately $50.8 million and $63.7 million, respectively, as of January 1, 2019. These increases did not have a material impact on our results of operations or cash flows.
For all leases that commenced before the effective date of ASC 842, we elected to apply the permitted practical expedients to not reassess the following: (1) whether any expired or existing contracts contain leases; (2) the lease classification for any expired or existing leases; and (3) initial direct costs for any existing leases.
We determine if an arrangement is a lease at inception of a contract. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense. We have lease agreements which require payments for lease and non-lease components and have elected to account for these as a single lease component related to our other operating facilities.
We have operating leases for office space, other operating facilities, vehicles and office equipment. Our fixed operating lease costs for the three and six months ended June 30, 2019 were $3.8 million and $7.6 million, respectively, and are included in general and administrative expenses on our Consolidated Statements of Operations. During the six months ended June 30, 2019, cash paid for amounts included in the measurement of operating lease liabilities was $8.1 million.

7. | Stockholders' Equity

During the first six months of 2019, we repurchased or withheld an aggregate of 315,369 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 six months ended June 30, 2019, 88,210 shares were repurchased under the Repurchase Program. As of June 30, 2019, we were authorized to repurchase an additional 1,522,945 shares under the Repurchase Program.
Withheld Shares
During the six months ended June 30, 2019, we withheld 227,159 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) | 2019 |  |  | 2018 |
First quarter | $ | 0.30 |  |  | $ | 0.20 |
Second quarter | 0.30 |  |  | 0.20 |

During the six months ended June 30, 2019 and 2018, we paid dividends totaling $24.7 million and $16.8 million, respectively.

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:

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 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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

claims concerning allegations of excessive recordkeeping fees. The court has denied plaintiffs’ request for a jury trial and has set a bench trial for March 2, 2020. With respect to plaintiffs’ remaining claims, plaintiffs allege damages up to $128 million against all defendants. We believe we have meritorious defenses, 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.

Results of Operations
Key Operating Metrics
We monitor certain key metrics to measure our performance, including:

• | WSEE

• | 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 second quarter of 2019 (“Q2 2019”), the number of WSEEs paid from new client sales increased over the second quarter of 2018 (“Q2 2018”) due to an 11.1% increase in the number of Business Performance Advisors. Additionally, client retention remained at high levels with a retention rate just above 99% in both periods. Net gains in our client base during Q2 2019 declined compared to Q2 2018 due to less hiring of full-time and seasonal employees.

• | During the first six months of 2019 (“YTD 2019”), the number of WSEEs paid from new client sales increased over the first six months of 2018 (“YTD 2018”) due to a 9.9% increase in the number of Business Performance Advisors. Additionally, client retention remained consistent compared to YTD 2018. Net gains in our client base declined compared to YTD 2018 due to less hiring of full-time and seasonal employees.

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.

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

Gross Profit per WSEE per Month and Year-over-Year Growth Percentage

Second Quarter 2019 Compared to Second Quarter 2018
Gross profit for Q2 2019 increased 12.4% to $173.7 million compared to $154.5 million in Q2 2018. Gross profit per WSEE per month for Q2 2019 decreased $3 to $250 compared to $253 in Q2 2018.
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 $8 and $5, respectively, due primarily to lower benefit participation in Q2 2019. The net decrease in costs between Q2 2019 and Q2 2018 due to the changes in cost estimates for benefits and workers’ compensation totaled $5.1 million as discussed below. The primary direct cost components changed as follows:
Benefits costs

• | Th e cost of group health insurance and related employee benefits was flat on a per WSEE per month basis, due in part to the decrease in medical participation noted below, but increased 3.1% on a cost per covered employee basis due in part to an increase in large claim activity during the period.

Insperity | 2019 Second Quarter Form 10-Q | 25

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

• | The percentage of WSEEs covered under our health insurance plans was 66.6% in Q2 2019 compared to 68.6% in Q2 2018 due in part to a large client added in the third quarter of 2018 not covered under our medical plan.

• | Changes in estimated claims run-off related to prior periods was a charge of $7.3 million, or $10 per WSEE per month, in Q2 2019 compared to a charge of $6.8 million, or $11 per WSEE per month, in Q2 2018.

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 18.3%, or $9 on a per WSEE per month basis, in Q2 2019 compared to Q2 2018.

• | As a percentage of non-bonus payroll cost, workers’ compensation costs in Q2 2019 were 0.34% compared to 0.48% in Q2 2018.

• | As a result of closing out claims at lower than expected costs, we recorded a reduction in workers’ compensation costs of $11.8 million, or 0.24% of non-bonus payroll costs, in Q2 2019 compared to a reduction of $6.2 million, or 0.14% of non-bonus payroll costs, in Q2 2018.

Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Workers’ Compensation Costs,” for a discussion of our accounting for workers’ compensation costs.
Payroll tax costs

• | Payroll taxes increased 14.6% on a 15.2% increase in payroll costs, or $4 per WSEE per month.

• | Payroll taxes as a percentage of payroll costs were 6.9% in both Q2 2019 and Q2 2018.

First Six Months 2019 Compared to First Six Months 2018
Gross profit for YTD 2019 increased 13.0% to $400.5 million compared to $354.3 million in YTD 2018. Gross profit per WSEE per month for YTD 2019 decreased $3 to $292 compared to $295 in YTD 2018.
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 $15 and $12, respectively, due primarily to lower benefit participation in YTD 2019. The net decrease in costs between YTD 2019 and YTD 2018 due to the changes in cost estimates for benefits and workers’ compensation totaled $2.7 million as discussed below. The primary direct cost components changed as follows:
Benefits costs

• | Th e cost of group health insurance and related employee benefits decreased $2 per WSEE per month, due in part to the decrease in medical participation noted below, but increased 2.9% on a cost per covered employee basis due in part to an increase in large claim activity during the period.

• | The percentage of WSEEs covered under our health insurance plans was 67.0% in YTD 2019 compared to 69.1% in YTD 2018 due in part to a large client added in the third quarter of 2018 not covered under our medical plan.

• | Changes in estimated claims run-off related to prior periods was a charge of $3.5 million, or $3 per WSEE per month, in YTD 2019 compared to a reduction of $1.9 million, or $2 per WSEE per month, in YTD 2018.

Operating expenses for Q2 2019 increased 11.6% to $135.0 million compared to $121.0 million in Q2 2018. Operating expenses per WSEE per month for Q2 2019 decreased 2.0% to $194 compared to $198 in Q2 2018.

• | Salaries of corporate and sales staff for Q2 2019 increased 8.7% to $74.7 million, but decreased $5 per WSEE per month basis, compared to Q2 2018. This increase was primarily due to a 12% increase in corporate headcount, which was partially offset by lower incentive compensation expense in Q2 2019 compared to Q2 2018.

• | Stock based compensation expense for Q2 2019 increased 43.5% to $8.3 million, or $1 per WSEE per month, compared to Q2 2018. The increase was primarily due to awards issued under our restricted stock and Long-Term Incentive Program.

• | Commissions expense for Q2 2019 increased 10.9% to $7.7 million, but remained flat on a per WSEE per month basis, compared to Q2 2018. 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 2019.

• | Advertising expense for Q2 2019 increased 14.6% to $7.5 million, but remained flat on a per WSEE per month basis, compared to Q2 2018. The increase was primarily due to an increase in television advertising and promotions.

• | General and administrative expenses for Q2 2019 increased 8.9% to $29.9 million, but decreased $2 on a per WSEE per month basis, compared to Q2 2018. The increase was primarily due to increased travel and training expenses associated with the increase in BPAs and technology maintenance costs.

• | Depreciation and amortization expense for Q2 2019 increased 26.1% to $6.9 million, or $2 per WSEE per month, compared to Q2 2018. The increase was primarily due to increased capital expenditures related to software development costs and sales office expansions.

Operating expenses for YTD 2019 increased 7.9% to $276.3 million compared to $256.0 million in YTD 2018. Operating expenses per WSEE per month for YTD 2019 decreased 6.1% to $201 compared to $214 in YTD 2018.

• | Salaries of corporate and sales staff for YTD 2019 increased 1.4% to $158.1 million, but decreased $15 on a per WSEE per month basis, compared to YTD 2018. This increase was primarily due to an 11.7% increase in corporate headcount, partially offset by the non-recurrence of a $9.3 million one-time tax reform bonus paid in the first quarter of 2018 (“Q1 2018”) and lower incentive compensation expense in YTD 2019 compared to YTD 2018.

• | Stock based compensation expense for YTD 2019 increased 60.9% to $14.3 million or $3 per WSEE per month, compared to YTD 2018. The increase was primarily due to the acceleration of restricted stock awards and associated expense into the fourth quarter of 2017 that were originally scheduled to vest in Q1 2018.

• | Commissions expense for YTD 2019 increased 12.6% to $14.7 million, but remained flat on a per WSEE per month basis, compared to YTD 2018.

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

For the three months ended June 30, 2019, our provision for income taxes differed from the U.S. statutory rate of 21% primarily due to state income taxes and non-deductible expenses.
For the six months ended June 30, 2019, 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 six months of 2019 and 2018, we recognized an income tax benefit of $14.5 million and $3.7 million, respectively, related to the vesting of long-term incentive in both periods 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 period, 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 operating expense | Represents operating expenses excluding the impact of the following: • costs associated with a one-time tax reform bonus paid to corporate employees.
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, and • costs associated with a one-time tax reform bonus paid to corporate employees.
Adjusted Net Income | Represents net income computed in accordance with GAAP, excluding: • non-cash stock based compensation, and • costs associated with a one-time tax reform bonus paid to corporate employees.
Adjusted EPS | Represents diluted net income per share computed in accordance with GAAP, excluding: • non-cash stock based compensation, and • costs associated with a one-time tax reform bonus paid to corporate employees.

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

Insperity | 2019 Second Quarter Form 10-Q | 32

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

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 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 $386.1 million in cash, cash equivalents and marketable securities at June 30, 2019, of which approximately $218.0 million was payable in early July 2019 for withheld federal and state income taxes, employment taxes and other payroll deductions, and approximately $37.4 million were client prepayments that were payable in July 2019. At June 30, 2019, we had working capital of $149.3 million compared to $94.2 million at December 31, 2018. We currently believe that our cash on hand, marketable securities, cash flows from operations and availability under our revolving credit facility will be adequate to meet our liquidity requirements for the remainder of 2019. 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.
We have a $350 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. As of June 30, 2019, we had an outstanding letter of credit and borrowings totaling $170.4 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 six months of 2019 was $72.4 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 June 30, 2019, the last business day of the reporting period was a Friday, client prepayments were $37.4 million and employment taxes and other deductions were $218.0 million. In the period ended June 30, 2018, the last business day of the reporting period was also a Friday, client prepayments were $14.0 million and employment taxes and other deductions were $191.9 million.

• | Medical plan funding – Our health care contract with United establishes participant cash funding rates 90 days in advance of the beginning of a reporting quarter. Therefore, changes in the participation level of the United plan have a direct impact on our operating cash flows. In addition, changes to the funding rates, which are solely determined by United based primarily upon recent claim history and anticipated cost trends, also have a significant impact on our operating cash flows. As of June 30, 2019, premiums owed and cash funded to United have exceeded the costs of the United plan, resulting in an $16.4 million surplus, $7.4 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 June 30, 2019, were $15.0 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 31.5% to $116.1 million in the first six months ended June 30, 2019, compared to $88.2 million in the first six months ended June 30, 2018. Please read “Results of Operations – First Six Months Ended June 30, 2019 Compared to First Six Months Ended June 30, 2018.”

Cash Flows from Investing Activities
Net cash flows used in investing activities were $17.2 million for the six months ended June 30, 2019, primarily due to property and equipment purchases of $17.2 million.
Cash Flows from Financing Activities
Net cash flows used in financing activities were $34.8 million for the six months ended June 30, 2019. We repurchased or withheld $38.8 million in stock, paid $24.7 million in dividends and borrowed $25.0 million on our revolving line of credit for general corporate purposes.

Insperity | 2019 Second Quarter Form 10-Q | 33

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 June 30, 2019, we had outstanding letters of credit and borrowings totaling $170.4 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 pre-funded municipal bonds that are secured by escrow funds containing 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 June 30, 2019.
There has been no change in our internal controls over financial reporting that occurred during the three months ended June 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

OTHER INFORMATION

These factors are discussed in further detail in our Annual Report on Form 10-K for the year ended December 31, 2018 under “Item 1A. Risk Factors” in Part I and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, and elsewhere in this report. Any of these factors, or a combination of such factors, could materially affect the results of our operations and whether forward-looking statements we make ultimately prove to be accurate.
Except to the extent otherwise required by federal securities law, we do not undertake any obligation to update our forward-looking statements to reflect events or circumstances after the date they are made or to reflect the occurrence of unanticipated events.
In addition, please read the following together with “Risk Factors -- Changes in federal, state and local regulation or our inability to obtain licenses under new regulatory frameworks could have a material adverse effect on our results of operations or financial condition” under “Item 1A. Risk Factors” in Part I of our Annual Report on Form 10-K for the year ended December 31, 2018:
On April 19, 2019, the Internal Revenue Service released an advice memorandum from the Office of the Chief Counsel concerning the IRS’s interpretations of proposed regulations regarding the reporting of remuneration and associated payroll taxes related to WSEEs of Certified Professional Employer Organizations (CPEOs) who are also deemed self-employed owners of client companies for federal tax purposes. The memorandum advises that CPEOs should not report remuneration paid to such self-employed owners on Form W-2 or subject such remuneration to federal employment taxes. As an employer, we have historically reported remuneration and associated payroll taxes processed on Form W-2 for all WSEEs, including those who would be deemed self-employed owners of client companies. Accordingly, we are in the process of transitioning our reporting and payroll tax processing methods for self-employed owners to those described in the memorandum. Our failure to successfully make such a transition could have a material adverse impact on our business and operations, including our ability to attract and retain clients.
