NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2012

(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 business offering is provided through our professional employer organization (“PEO”) services, known as Workforce OptimizationTM, which encompasses a broad range of HR functions, including payroll and employment administration, employee benefits, workers’ compensation, government compliance, performance management, and training and development services.

In addition to Workforce Optimization, we offer Performance Management, Expense Management, Time and Attendance, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services and Business Insurance, (collectively “Adjacent Businesses”), many of which are offered via desktop applications and software as a service (“SaaS”) delivery models.  These other products or services are offered separately, as a bundle, or along with Workforce Optimization (“Bundle Plus”).

We provide our Workforce Optimization solution to small and medium-sized businesses in strategically selected markets throughout the United States.  For the three months ended March 31, 2012 and 2011, Workforce Optimization revenues from Insperity’s Texas markets represented 26% and 27%, while Workforce Optimization revenues from Insperity’s California markets represented 17% and 16%, of Insperity’s total Workforce Optimization revenues, respectively.

The Consolidated Financial Statements include the accounts of Insperity and its subsidiaries, all of which are wholly owned.  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 as of and for the year ended December 31, 2011. Our Consolidated Balance Sheets at December 31, 2011 have been derived from the audited financial statements at that date, but do not include all of the information or footnotes required by GAAP for complete financial statements.  Our Consolidated Balance Sheets at March 31, 2012 and the Consolidated Statements of Operations, Comprehensive Income and Cash Flows for the periods ended March 31, 2012 and 2011, and Stockholders’ Equity for the period ended March 31, 2012, 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.

- 10 -

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 worksite employees through a national network of carriers, including UnitedHealthcare (“United”), Kaiser Permanente, Blue Shield of California, HMS BlueCross BlueShield, Unity Health Plan and Tufts, all of which provide fully insured policies or service contracts.

The policy with United provides the majority of our health insurance coverage.  As a result of certain contractual terms, Insperity has accounted for this plan since its inception using a partially self-funded insurance accounting model.  Accordingly, Insperity records the costs of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”) as benefits expense in the Consolidated Statements of Operations.  The estimated incurred claims are based upon: (i) the level of claims processed during the quarter; (ii) estimated completion rates based upon recent claim development patterns under the plan; and (iii) 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.

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 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 Consolidated Balance Sheets.  The terms of the arrangement require Insperity 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 $2.8 million as of March 31, 2012, and is reported as a long-term asset.  As of March 31, 2012, Plan Costs were less than the net premiums paid and owed to United by $28.9 million.  As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $19.9 million balance is included in prepaid insurance, a current asset, in our Consolidated Balance Sheets.  The premiums owed to United at March 31, 2012 were $5.8 million, which is included in accrued health insurance costs, a current liability in our Consolidated Balance Sheets.

- 11 -

Workers’ Compensation Costs

Insperity’s workers’ compensation coverage has been provided through an arrangement with the ACE Group of Companies (“the ACE Program”) since 2007.  The ACE Program is fully insured in that ACE has the responsibility to pay all claims incurred regardless of whether Insperity satisfies its responsibilities.  Through September 30, 2010, Insperity bore the economic burden for the first $1 million layer of claims per occurrence and the insurance carrier was and remains responsible for the economic burden for all claims in excess of such first $1 million layer.

Effective October 1, 2010, in addition to our bearing the economic burden for the first $1 million layer of claims per occurrence, we also bear the economic burden for those claims exceeding $1 million, up to a maximum aggregate amount of $5 million per policy year.

Because we bear the economic burden 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.

Insperity employs a third party actuary to estimate its loss development rate, which is primarily based upon the nature of worksite employees’ job responsibilities, the location of worksite employees, 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 three months ended March 31, 2012 and 2011, Insperity reduced accrued workers’ compensation costs by $3.5 million and $1.9 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 rates utilized in 2012 and 2011 were 1.0% and 1.5%, respectively) and are accreted over the estimated claim payment period and included as a component of direct costs in our Consolidated Statements of Operations.

- 12 -

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

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Beginning balance, January 1,	$	104,791		$	96,934
Accrued claims		9,495			9,790
Present value discount		(347	)		(530	)
Paid claims		(6,976	)		(7,533	)
Ending balance	$	106,963		$	98,661
Current portion of accrued claims	$	45,068		$	40,807
Long-term portion of accrued claims		61,895			57,854
	$	106,963		$	98,661

The current portion of accrued workers’ compensation costs on the Consolidated Balance Sheets at March 31, 2012 includes $2.0 million of workers’ compensation administrative fees.

As of March 31, 2012 and 2011, the undiscounted accrued workers’ compensation costs were $120.1 million and $113.1 million, respectively.

At the beginning of each policy period, the 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 worksite employee 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, a long-term asset in our Consolidated Balance Sheets.  As of March 31, 2012, we had restricted cash of $45.1 million and deposits of $55.7 million.

Insperity’s estimate of incurred claim costs expected to be paid within one year are recorded as accrued workers’ compensation costs and included in short-term liabilities, while its estimate of incurred claim costs expected to be paid beyond one year are included in long-term liabilities on our Consolidated Balance Sheets.

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:

Marketable securities		56,981			56,987
	$	291,529		$	268,195

Our cash and overnight holdings fluctuate based on the timing of the client’s payroll processing cycle.  Included in the cash balance as of March 31, 2012 and December 31, 2011, are $165.8 million and $150.8 million, respectively, in funds associated with federal and state income tax withholdings, employment taxes and other payroll deductions, as well as $10.7 million and $10.4 million in client prepayments, respectively.

Insperity accounts for its financial assets in accordance with Accounting Standard Codification (“ASC”) 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

- 14 -

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

	Fair Value Measurements

	2012		Level 1		Level 2		Level 3
Money market funds	$	146,842	$	146,842	$	—	$	—

Municipal bonds		56,987		—		56,987		—
Total	$	187,924	$	130,937	$	56,987	$	—

The municipal bond securities valued as Level 2 investments are primarily pre-refunded municipal bonds that are secured by escrow funds containing U.S. Government securities. Valuation techniques used by Insperity 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:

			Gross		Gross
	Amortized		Unrealized		Unrealized			Estimated
	Cost		Gains		Losses			Fair Value
			(in thousands)
March 31, 2012:
Municipal bonds	$	56,882	$	117	$	(18	)	$	56,981
December 31, 2011:
Municipal bonds	$	56,945	$	90	$	(48	)	$	56,987

During the periods ended March 31, 2012 and 2011, we had no realized gains or losses recognized on sales of marketable securities.

- 15 -

As of March 31, 2012, the contractual maturities of our marketable securities were as follows:

	Amortized Cost		Estimated Fair Value
	(in thousands)
Less than one year	$	33,566	$	33,576
One to five years		23,316		23,405
Total	$	56,882	$	56,981

4.  Acquisitions

Insperity accounts for its acquisitions in accordance with ASC 805, Business Combinations, which requires allocation of the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on the fair value at the date of purchase.  The purchase price in excess of the identifiable assets and liabilities is recorded to goodwill.  All acquisition related costs are expensed as incurred and recorded in operating expenses.  We include operations associated with acquisitions from the date of acquisition forward.

In January 2011, Insperity acquired from HumanConcepts, a provider of workforce decision support solutions, ownership of its OrgPlus desktop software product line for small and medium-sized businesses, and its associated customer base, as well as a source code license for a SaaS-based version. OrgPlus facilitates creation, management and communication of detailed organizational charts. The acquisition reflects Insperity’s continued business strategy to expand its HR services as well as the solutions available to our current and prospective clients.  We paid $10.8 million upon the closing of the transaction and paid an additional $1.2 million in January 2012 based on the terms of the agreement.

5. Revolving Credit Facility

On September 15, 2011, we entered into a four-year, $100 million revolving credit facility (the “Facility”), which may be increased to $150 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. Insperity’s 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.  In January 2012, we issued an irrevocable standby letter of credit for $285,000 under the Facility to a state workers’ compensation agency.  At March 31, 2012, we had not drawn on the Facility.

The Facility matures on September 15, 2015.  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 (i) in the case of LIBOR loans, from 2.00% to 2.75%; and (ii) in the case of alternate base rate loans, from 0.00% to 0.75%.  The alternate base rate is the highest of (i) the prime rate most recently published in The Wall Street Journal; (ii) the federal funds rate plus 0.50%; and (iii) 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%. Interest expense and unused commitment fees are recorded in other income (expense).

The Facility contains both affirmative and negative covenants, which 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 March 31, 2012.

6. Stockholders’ Equity

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 three months ended March 31, 2012, no shares were repurchased under the Repurchase Program; however, 105,923 shares were withheld to satisfy tax withholding obligations for the vesting of restricted stock awards.  These shares are not subject to the Repurchase Program.  As of March 31, 2012, we were authorized to repurchase an additional 1,236,872 shares under the program.

The Board declared quarterly dividends of $0.15 per share of common stock in the first quarter of 2012 and 2011, resulting in a total of $3.9 million and $4.0 million, respectively, in dividend payments made by Insperity during the three months ended March 31 of each year.

7. Net Income per Share

We utilize the two-class method to compute net income per share.  The two-class method allocates a portion of net income to participating securities, which include 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.  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.

- 17 -

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 March 31,
	2012			2011
	(in thousands)
Net income	$	13,884		$	8,786
Less income allocated to participating securities		(402	)		(264	)
Net income allocated to common shares	$	13,482		$	8,522
Weighted average common shares outstanding		25,087			25,488
Incremental shares from assumed conversions of common stock options		71			119
Adjusted weighted average common shares outstanding		25,158			25,607
Potentially dilutive securities not included in weighted average share calculation due to anti-dilutive effect		16			—

8.           Commitments and Contingencies

Insperity is a defendant in various 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.

Pennsylvania Sales Taxes

Pennsylvania imposes a sales tax on “help supply services.”  The Pennsylvania Department of Revenue (“Department”) has maintained that PEO services constitute help supply services and are subject to the tax.  On February 21, 2012, the Pennsylvania Supreme Court (“Supreme Court”) affirmed the Appeals Court decision in the matter titled All Staffing vs. Commonwealth of Pennsylvania, which ruled that PEO services are not subject to the Pennsylvania sales tax.

Based upon our belief that our PEO services are not subject to the Pennsylvania sales tax, we filed a refund claim for $2.9 million with the Department for the sales taxes paid in error for the period April 1, 2007 through December 31, 2009.  The refund claim is still under consideration with the Department and the ultimate outcome and timing of our recovery, if any, is uncertain. Accordingly, we have not recognized any asset for the refund claim in our financial statements.  In the event we are successful in our refund claim, we will recognize a gain equal to the recovered amount.

(1) Gross billings of $8,833 and $8,566 per worksite employee per month, less payroll cost of $7,206 and $6,975 per worksite employee per month, respectively.

Revenues

Our revenues for the first quarter of 2012 increased 11.0% over the 2011 period, primarily due to an 8.5% increase in the average number of worksite employees paid per month and a 2.3%, or $36 increase in revenues per worksite employee per month.

- 19 -

By region, our Workforce Optimization revenue change from the first quarter of 2011 and distribution for the quarters ended March 31, 2012 and 2011 were as follows:

	Three Months Ended March 31,							Three Months Ended March 31,
	2012		2011		% Change			2012			2011
	(in thousands)							(% of total revenues)
Northeast	$	158,965	$	140,745		12.9	%		27.0	%		26.6	%
Southeast		53,348		51,375		3.8	%		9.1	%		9.7	%

		588,019		529,651		11.0	%		100.0	%		100.0	%
Other revenue		7,158		6,820		5.0	%
Total revenue	$	595,177	$	536,381		11.0	%

Other revenue is comprised primarily of revenues generated by our Adjacent Businesses.

Our Workforce Optimization growth rate is affected by three primary sources – worksite employees paid from new client sales, client retention and the net change in existing clients through worksite employee new hires and layoffs.  During the first quarter of 2012, the net change in existing clients improved as compared to the first quarter of 2011, while worksite employees paid from new client sales declined and client retention remained consistent with the first quarter of 2011.

Gross Profit

Gross profit for the first quarter of 2012 increased 13.2% over the first quarter of 2011 to $103.0 million.  The average gross profit per worksite employee increased 4.4% to $282 per month in the 2012 period from $270 per month in the 2011 period.  Included in gross profit in 2012 is a $10 per worksite employee per month contribution from our Adjacent Businesses compared to $11 per worksite employee per month in the 2011 period.  Our pricing objectives attempt to maintain or improve the gross profit per worksite employee by increasing revenue per worksite employee to match or exceed changes in primary direct costs and operating expenses.

While our revenues increased 2.3% per worksite employee per month, our direct costs, which primarily include payroll taxes, benefits and workers’ compensation expenses, increased 1.8% to $1,345 per worksite employee per month in the first quarter of 2012 versus $1,321 in the first quarter of 2011.

· Benefits costs – The cost of group health insurance and related employee benefits increased $7 per worksite employee per month, or 3.6% on a cost per covered employee basis compared to the first quarter of 2011.  These results reflect typical annual cost increases and were favorably impacted by plan design changes implemented on January 1, 2012, and a decrease in the number of COBRA participants.  The number of participants electing COBRA coverage in the United plan declined from 4.5% in the first quarter of 2011 to 3.1% in the first quarter of 2012 due primarily to the August 2011 expiration of the 65% federal premium subsidy provided to COBRA eligible participants under the American Recovery and Reinvestment Act of 2009.  Historically, the net costs of COBRA claims per enrollee are approximately double the cost of claims associated with active enrollees.  The percentage of worksite employees covered under our health insurance plans was 72.8% in the 2012 period compared to 74.5% in the 2011 period.  Please read Note 2 to the Consolidated Financial Statements, “Accounting Policies – Health Insurance Costs,” for a discussion of our accounting for health insurance costs.

- 20 -

· Workers’ compensation costs – Workers’ compensation costs increased 1.7%, but decreased $2 per worksite employee per month, compared to the first quarter of 2011.  As a percentage of non-bonus payroll cost, workers’ compensation costs were 0.56% in the 2012 period compared to 0.61% in the 2011 period.  During the 2012 period, we recorded reductions in workers’ compensation costs of $3.5 million, or 0.15% of non-bonus payroll costs, for changes in estimated losses related to prior reporting periods, compared to $1.9 million, or 0.09% of non-bonus payroll costs, in the 2011 period.  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 11.5%, or $19 per worksite employee per month compared to the first quarter of 2011, primarily due to the 12.1% increase in payroll costs.  Payroll taxes as a percentage of payroll cost were 9.6% in both the 2012 and 2011 periods.

Operating Expenses

The following table presents certain information related to our operating expenses:

	Three Months Ended March 31,							Three Months Ended March 31,
	2012		2011		% Change			2012		2011		% Change
	(in thousands)							(per worksite employee per month)

Total operating expenses	$	79,958	$	75,830		5.4	%	$	219	$	225		(2.7	)%

Operating expenses increased 5.4% to $80.0 million compared to $75.8 million in the first quarter of 2011.  Operating expenses in the first quarter of 2011 included costs associated with the launch of our new brand.  Operating expenses per worksite employee per month decreased to $219 in the 2012 period from $225 in the 2011 period.  The components of operating expenses changed as follows:

- 21 -

· Salaries, wages and payroll taxes of corporate and sales staff increased 9.4%, or $1 per worksite employee per month compared to the 2011 period.  This increase was primarily due to a 9.4% rise in headcount, due in part to our adjacent business strategy.

· Stock-based compensation increased 20.4%, or $1 per worksite employee per month compared to the 2011 period, due primarily to an increase in the weighted average market value on the date of grant associated with restricted awards.  The stock-based compensation expense represents amortization of restricted stock awards granted to employees.

· Commissions expense increased 10.9%, due primarily to an 8.5% increase in the average number of worksite employees paid per month.  Commissions expense remained flat on a per worksite employee per month basis compared to the 2011 period.

· Advertising costs decreased 13.6%, or $3 per worksite employee per month compared to the 2011 period, primarily due to the non-recurrence of expenses in 2012 related to our rebranding initiative.

· General and administrative expenses increased 0.8%, but decreased $5 per worksite employee per month compared to the first quarter of 2011, primarily due to increased professional services, office and repairs and maintenance, offset by the non-recurrence of expenses in 2012 related to our rebranding initiative.

· Depreciation and amortization expense increased 6.7%, but remained flat on a per worksite employee per month basis compared to the 2011 period.

Income Tax Expense

Our effective income tax rate was 40.5% in the 2012 period compared to 43.0% in the 2011 period.  Our provision for income taxes differed from the U.S. statutory rate of 35% primarily due to state income taxes and non-deductible expenses.

Operating and Net Income

Operating and net income per worksite employee per month was $63 and $38 in the 2012 period, versus $45 and $26 in the 2011 period.

- 22 -

Non-GAAP Financial Measures

Non-bonus payroll cost is a non-GAAP financial measure that excludes the impact of bonus payrolls paid to our worksite employees.  Bonus payroll cost varies from period to period, but has no direct impact to our ultimate workers’ compensation costs under the current program.  As a result, our management refers to non-bonus payroll cost in analyzing, reporting and forecasting our workers’ compensation costs.  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.  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.  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 table below.

	Three Months Ended March 31,
	2012			2011			% Change
	(in thousands, except per worksite employee per month data)
Payroll cost (GAAP)	$	2,636,129		$	2,352,263			12.1	%
Less: Bonus payroll cost		(367,823	)		(304,849	)		20.7	%
Non-bonus payroll cost	$	2,268,306		$	2,047,414			10.8	%
Payroll cost per worksite employee per month (GAAP)	$	7,206		$	6,975			3.3	%
Less: Bonus payroll cost per worksite employee per month		(1,005	)		(904	)		11.2	%
Non-bonus payroll cost per worksite employee per month	$	6,201		$	6,071			2.1	%

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, acquisition plans and other operating cash needs.  To meet short- and long-term liquidity requirements, including payment of direct and operating expenses and repaying debt, we rely primarily on cash from operations.  However, 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 $291.5 million in cash, cash equivalents and marketable securities at March 31, 2012, of which approximately $165.8 million was payable in early April 2012 for withheld federal and state income taxes, employment taxes and other payroll deductions, and approximately $10.7 million of client prepayments that were payable in April 2012.  At March 31, 2012, we had working capital of $135.9 million compared to $126.6 million at December 31, 2011.  We currently believe that our cash on hand and cash flows from operations will be adequate to meet our liquidity requirements for the remainder of 2012.  We will rely on these same sources, as well as public and private debt or equity financing, to meet our longer-term liquidity and capital needs.

- 23 -

In September 2011, we completed the financing for a new four-year, $100 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 was undrawn at March 31, 2012.  Please read Note 5 to our Consolidated Financial Statements, “Revolving Credit Facility,” for additional information.

Cash Flows from Operating Activities

Net cash provided by operating activities in 2012 was $33.3 million.  Our primary source of cash from operations is the comprehensive service fee and payroll funding we collect from our clients.  The level of 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 / payrolls – 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 worksite employee 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 worksite employees are paid on Fridays; therefore, operating cash flows decrease in the reporting periods that end on a Friday.  In the period ended March 31, 2012, the last business day of the reporting period was a Friday and client prepayments were $10.7 million and accrued worksite employee payroll was $144.8 million.  In the period ended March 31, 2011, the last business day of the reporting period was a Thursday and client prepayments were $57.7 million and accrued worksite employee payroll was $166.3 million.

· Workers’ compensation plan funding – Under our workers’ compensation insurance arrangements, we make monthly payments to the carriers comprised of premium costs and funds to be set aside for payment of future claims (“claim funds”).  These pre-determined amounts are stipulated in our agreements with the carriers, and are based primarily on anticipated worksite employee payroll levels and workers’ compensation loss rates during the policy year.  Changes in payroll levels from those that were anticipated in the arrangements can result in changes in the amount of cash payments, which will impact our reporting of operating cash flows.  Our claim funds paid, based upon anticipated worksite employee payroll levels and workers’ compensation loss rates, were $10.6 million in the first three months of 2012 and $9.1 million in the first three months of 2011. However, our estimate of workers’ compensation loss costs was $9.1 million and $9.3 million in 2012 and 2011, respectively.

- 24 -

· 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.  At March 31, 2012, premiums owed and cash funded to United have exceeded Plan Costs, resulting in a $28.9 million surplus, $19.9 million of which is reflected as a current asset, and $9.0 million of which is reflected as a long-term asset on our Consolidated Balance Sheets.  The premiums owed to United at March 31, 2012, were $5.8 million, which is included in accrued health insurance costs, a current liability, on our Consolidated Balance Sheets.

· Operating results – Our net income has a significant impact on our operating cash flows.  Our net income increased 58.0% to $13.9 million in the three months ended March 31, 2012, compared to $8.8 million in the three months ended March 31, 2011.  Please read “Results of Operations – Three Months Ended March 31, 2012 Compared to Three Months Ended March 31, 2011.”

Cash Flows from Investing Activities

Net cash flows used in investing activities were $5.2 million for the three months ended March 31, 2012, primarily due to $3.4 million in capital expenditures primarily related to our technology infrastructure.

Cash Flows from Financing Activities

Net cash flows used in financing activities were $4.7 million for the three months ended March 31, 2012, including $3.3 million in stock repurchases related to shares withheld to satisfy tax withholding obligations for the vesting of restricted stock awards and $3.9 million in dividends paid.

- 25 -

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.   In addition, borrowings under our Facility bear interest at a variable market rate.  As of March 31, 2012, we had not drawn on the Facility.  Please read Note 5 to the Consolidated Financial Statements, “Revolving Credit Facility,” for additional information.  Our cash equivalent short-term investments consist primarily of overnight investments and money market funds, 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.  The 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 and intermediate-term debt securities, which are primarily prefunded municipal bonds that are secured by escrow funds containing U.S. Government Securities.

ITEM 4.  CONTROLS AND PROCEDURES.

In accordance with the Securities Exchange Act of 1934 Rules 13a-15 and 15d-15, 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 March 31, 2012.

There has been no change in our internal controls over financial reporting that occurred during the three months ended March 31, 2012, 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 8 to our Consolidated Financial Statements, 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 Securities Exchange Act of 1934).  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 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: (i) continued effects of the economic recession and general economic conditions; (ii) regulatory and tax developments and possible adverse application of various federal, state and local regulations; (iii) the ability to secure competitive replacement contracts for health insurance and workers’ compensation contracts at expiration of current contracts; (iv) increases in health insurance costs and workers’ compensation rates and underlying claims trends, health care reform, financial solvency of workers’ compensation carriers and other insurers, state unemployment tax rates, liabilities for employee and client actions or payroll-related claims; (v) failure to manage growth of our operations and the effectiveness of our sales and marketing efforts; (vi) changes in the competitive environment in the PEO industry, including the entrance of new competitors and our ability to renew or replace client companies; (vii) our liability for worksite employee payroll, payroll taxes and benefits costs; (viii) our liability for disclosure of sensitive or private information; (ix) our ability to integrate or realize expected return on our adjacent business strategy, including acquisitions; and (x) an adverse final judgment or settlement of claims against Insperity.  These factors are discussed in further detail in our 2011 Annual Report on Form 10-K under “Factors That May Affect Future Results and the Market Price of Common Stock” on page 19, 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.

There have been no material changes in the risk factors disclosed pursuant to Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2011.

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table provides information about purchases by Insperity during the three months ended March 31, 2012, of equity securities that are registered by Insperity pursuant to Section 12 of the Exchange Act:

(1) The Board has approved a repurchase program of Insperity common stock. During the three months ended March 31, 2012, no shares were repurchased under the program and 105,923 shares were withheld to satisfy tax withholding obligations for the vesting of restricted stock awards.  As of March 31, 2012, we were authorized to repurchase an additional 1,236,872 shares under the program. Unless terminated earlier by resolution of the Board, the repurchase program will expire when we have repurchased all shares authorized for repurchase under the repurchase program.

(2) These shares were shares of restricted stock that were withheld to satisfy tax-withholding obligations arising in conjunction with the vesting of restricted stock.  The required withholding is calculated using the closing sales price reported by the New York Stock Exchange on the date prior to the applicable vesting date.  These shares are not subject to the repurchase program described above.

Accounting Policies

2.  Accounting Policies

Health Insurance Costs

We provide group health insurance coverage to our worksite employees through a national network of carriers, including UnitedHealthcare (“United”), Kaiser Permanente, Blue Shield of California, HMS BlueCross BlueShield, Unity Health Plan and Tufts, all of which provide fully insured policies or service contracts.

The policy with United provides the majority of our health insurance coverage.  As a result of certain contractual terms, Insperity has accounted for this plan since its inception using a partially self-funded insurance accounting model.  Accordingly, Insperity records the costs of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”) as benefits expense in the Consolidated Statements of Operations.  The estimated incurred claims are based upon: (i) the level of claims processed during the quarter; (ii) estimated completion rates based upon recent claim development patterns under the plan; and (iii) 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.

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 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 Consolidated Balance Sheets.  The terms of the arrangement require Insperity 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 $2.8 million as of March 31, 2012, and is reported as a long-term asset.  As of March 31, 2012, Plan Costs were less than the net premiums paid and owed to United by $28.9 million.  As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $19.9 million balance is included in prepaid insurance, a current asset, in our Consolidated Balance Sheets.  The premiums owed to United at March 31, 2012 were $5.8 million, which is included in accrued health insurance costs, a current liability in our Consolidated Balance Sheets.

Workers' Compensation Costs

Insperity's workers' compensation coverage has been provided through an arrangement with the ACE Group of Companies (“the ACE Program”) since 2007.  The ACE Program is fully insured in that ACE has the responsibility to pay all claims incurred regardless of whether Insperity satisfies its responsibilities.  Through September 30, 2010, Insperity bore the economic burden for the first $1 million layer of claims per occurrence and the insurance carrier was and remains responsible for the economic burden for all claims in excess of such first $1 million layer.

Effective October 1, 2010, in addition to our bearing the economic burden for the first $1 million layer of claims per occurrence, we also bear the economic burden for those claims exceeding $1 million, up to a maximum aggregate amount of $5 million per policy year.

Because we bear the economic burden 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.

Insperity employs a third party actuary to estimate its loss development rate, which is primarily based upon the nature of worksite employees' job responsibilities, the location of worksite employees, 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 three months ended March 31, 2012 and 2011, Insperity reduced accrued workers' compensation costs by $3.5 million and $1.9 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 rates utilized in 2012 and 2011 were 1.0% and 1.5%, respectively) 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:

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Beginning balance, January 1,	$	104,791		$	96,934
Accrued claims		9,495			9,790
Present value discount		(347	)		(530	)
Paid claims		(6,976	)		(7,533	)
Ending balance	$	106,963		$	98,661
Current portion of accrued claims	$	45,068		$	40,807
Long-term portion of accrued claims		61,895			57,854
	$	106,963		$	98,661

The current portion of accrued workers' compensation costs on the Consolidated Balance Sheets at March 31, 2012 includes $2.0 million of workers' compensation administrative fees.

As of March 31, 2012 and 2011, the undiscounted accrued workers' compensation costs were $120.1 million and $113.1 million, respectively.

At the beginning of each policy period, the 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 worksite employee 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, a long-term asset in our Consolidated Balance Sheets.  As of March 31, 2012, we had restricted cash of $45.1 million and deposits of $55.7 million.

Insperity's estimate of incurred claim costs expected to be paid within one year are recorded as accrued workers' compensation costs and included in short-term liabilities, while its estimate of incurred claim costs expected to be paid beyond one year are included in long-term liabilities on our Consolidated Balance Sheets.

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 business offering is provided through our professional employer organization (“PEO”) services, known as Workforce OptimizationTM, which encompasses a broad range of HR functions, including payroll and employment administration, employee benefits, workers' compensation, government compliance, performance management, and training and development services.

In addition to Workforce Optimization, we offer Performance Management, Expense Management, Time and Attendance, Organizational Planning, Recruiting Services, Employment Screening, Retirement Services and Business Insurance, (collectively “Adjacent Businesses”), many of which are offered via desktop applications and software as a service (“SaaS”) delivery models.  These other products or services are offered separately, as a bundle, or along with Workforce Optimization (“Bundle Plus”).

We provide our Workforce Optimization solution to small and medium-sized businesses in strategically selected markets throughout the United States.  For the three months ended March 31, 2012 and 2011, Workforce Optimization revenues from Insperity's Texas markets represented 26% and 27%, while Workforce Optimization revenues from Insperity's California markets represented 17% and 16%, of Insperity's total Workforce Optimization revenues, respectively.

The Consolidated Financial Statements include the accounts of Insperity and its subsidiaries, all of which are wholly owned.  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 as of and for the year ended December 31, 2011. Our Consolidated Balance Sheets at December 31, 2011 have been derived from the audited financial statements at that date, but do not include all of the information or footnotes required by GAAP for complete financial statements.  Our Consolidated Balance Sheets at March 31, 2012 and the Consolidated Statements of Operations, Comprehensive Income and Cash Flows for the periods ended March 31, 2012 and 2011, and Stockholders' Equity for the period ended March 31, 2012, 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.

Revolving Credit Facility

Revolving Credit Facility [Abstract]

Long-term Debt

5. Revolving Credit Facility

On September 15, 2011, we entered into a four-year, $100 million revolving credit facility (the “Facility”), which may be increased to $150 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. Insperity's 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.  In January 2012, we issued an irrevocable standby letter of credit for $285,000 under the Facility to a state workers' compensation agency.  At March 31, 2012, we had not drawn on the Facility.

The Facility matures on September 15, 2015.  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 (i) in the case of LIBOR loans, from 2.00% to 2.75%; and (ii) in the case of alternate base rate loans, from 0.00% to 0.75%.  The alternate base rate is the highest of (i) the prime rate most recently published in The Wall Street Journal; (ii) the federal funds rate plus 0.50%; and (iii) 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%. Interest expense and unused commitment fees are recorded in other income (expense).

The Facility contains both affirmative and negative covenants, which 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 March 31, 2012.

4.  Acquisitions

Insperity accounts for its acquisitions in accordance with ASC 805, Business Combinations, which requires allocation of the purchase price to tangible and identifiable intangible assets acquired and liabilities assumed based on the fair value at the date of purchase.  The purchase price in excess of the identifiable assets and liabilities is recorded to goodwill.  All acquisition related costs are expensed as incurred and recorded in operating expenses.  We include operations associated with acquisitions from the date of acquisition forward.

In January 2011, Insperity acquired from HumanConcepts, a provider of workforce decision support solutions, ownership of its OrgPlus desktop software product line for small and medium-sized businesses, and its associated customer base, as well as a source code license for a SaaS-based version. OrgPlus facilitates creation, management and communication of detailed organizational charts. The acquisition reflects Insperity's continued business strategy to expand its HR services as well as the solutions available to our current and prospective clients.  We paid $10.8 million upon the closing of the transaction and paid an additional $1.2 million in January 2012 based on the terms of the agreement.

Insperity is a defendant in various 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.

Pennsylvania Sales Taxes

Pennsylvania imposes a sales tax on “help supply services.”  The Pennsylvania Department of Revenue (“Department”) has maintained that PEO services constitute help supply services and are subject to the tax.  On February 21, 2012, the Pennsylvania Supreme Court (“Supreme Court”) affirmed the Appeals Court decision in the matter titled All Staffing vs. Commonwealth of Pennsylvania, which ruled that PEO services are not subject to the Pennsylvania sales tax.

Based upon our belief that our PEO services are not subject to the Pennsylvania sales tax, we filed a refund claim for $2.9 million with the Department for the sales taxes paid in error for the period April 1, 2007 through December 31, 2009.  The refund claim is still under consideration with the Department and the ultimate outcome and timing of our recovery, if any, is uncertain. Accordingly, we have not recognized any asset for the refund claim in our financial statements.  In the event we are successful in our refund claim, we will recognize a gain equal to the recovered amount.

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 three months ended March 31, 2012, no shares were repurchased under the Repurchase Program; however, 105,923 shares were withheld to satisfy tax withholding obligations for the vesting of restricted stock awards.  These shares are not subject to the Repurchase Program.  As of March 31, 2012, we were authorized to repurchase an additional 1,236,872 shares under the program.

The Board declared quarterly dividends of $0.15 per share of common stock in the first quarter of 2012 and 2011, resulting in a total of $3.9 million and $4.0 million, respectively, in dividend payments made by Insperity during the three months ended March 31 of each year.

Net Income Per Share

7. Net Income per Share

We utilize the two-class method to compute net income per share.  The two-class method allocates a portion of net income to participating securities, which include 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.  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:

Accounting Policies (Policies)

Accounting Policies [Abstract]

Health Insurance Costs

Health Insurance Costs

We provide group health insurance coverage to our worksite employees through a national network of carriers, including UnitedHealthcare (“United”), Kaiser Permanente, Blue Shield of California, HMS BlueCross BlueShield, Unity Health Plan and Tufts, all of which provide fully insured policies or service contracts.

The policy with United provides the majority of our health insurance coverage.  As a result of certain contractual terms, Insperity has accounted for this plan since its inception using a partially self-funded insurance accounting model.  Accordingly, Insperity records the costs of the United plan, including an estimate of the incurred claims, taxes and administrative fees (collectively the “Plan Costs”) as benefits expense in the Consolidated Statements of Operations.  The estimated incurred claims are based upon: (i) the level of claims processed during the quarter; (ii) estimated completion rates based upon recent claim development patterns under the plan; and (iii) 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.

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 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 Consolidated Balance Sheets.  The terms of the arrangement require Insperity 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 $2.8 million as of March 31, 2012, and is reported as a long-term asset.  As of March 31, 2012, Plan Costs were less than the net premiums paid and owed to United by $28.9 million.  As this amount is in excess of the agreed-upon $9.0 million surplus maintenance level, the $19.9 million balance is included in prepaid insurance, a current asset, in our Consolidated Balance Sheets.  The premiums owed to United at March 31, 2012 were $5.8 million, which is included in accrued health insurance costs, a current liability in our Consolidated Balance Sheets.

Workers' Compensation Costs

Workers' Compensation Costs

Insperity's workers' compensation coverage has been provided through an arrangement with the ACE Group of Companies (“the ACE Program”) since 2007.  The ACE Program is fully insured in that ACE has the responsibility to pay all claims incurred regardless of whether Insperity satisfies its responsibilities.  Through September 30, 2010, Insperity bore the economic burden for the first $1 million layer of claims per occurrence and the insurance carrier was and remains responsible for the economic burden for all claims in excess of such first $1 million layer.

Effective October 1, 2010, in addition to our bearing the economic burden for the first $1 million layer of claims per occurrence, we also bear the economic burden for those claims exceeding $1 million, up to a maximum aggregate amount of $5 million per policy year.

Because we bear the economic burden 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.

Insperity employs a third party actuary to estimate its loss development rate, which is primarily based upon the nature of worksite employees' job responsibilities, the location of worksite employees, 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 three months ended March 31, 2012 and 2011, Insperity reduced accrued workers' compensation costs by $3.5 million and $1.9 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 rates utilized in 2012 and 2011 were 1.0% and 1.5%, respectively) 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:

	Three Months Ended March 31,
	2012			2011
	(in thousands)
Beginning balance, January 1,	$	104,791		$	96,934

Long-term portion of accrued claims		61,895			57,854
	$	106,963		$	98,661

The current portion of accrued workers' compensation costs on the Consolidated Balance Sheets at March 31, 2012 includes $2.0 million of workers' compensation administrative fees.

As of March 31, 2012 and 2011, the undiscounted accrued workers' compensation costs were $120.1 million and $113.1 million, respectively.

At the beginning of each policy period, the 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 worksite employee 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, a long-term asset in our Consolidated Balance Sheets.  As of March 31, 2012, we had restricted cash of $45.1 million and deposits of $55.7 million.

Insperity's estimate of incurred claim costs expected to be paid within one year are recorded as accrued workers' compensation costs and included in short-term liabilities, while its estimate of incurred claim costs expected to be paid beyond one year are included in long-term liabilities on our Consolidated Balance Sheets.

Our cash and overnight holdings fluctuate based on the timing of the client's payroll processing cycle.  Included in the cash balance as of March 31, 2012 and December 31, 2011, are $165.8 million and $150.8 million, respectively, in funds associated with federal and state income tax withholdings, employment taxes and other payroll deductions, as well as $10.7 million and $10.4 million in client prepayments, respectively.

Insperity accounts for its financial assets in accordance with Accounting Standard Codification (“ASC”) 820, Fair Value Measurement.  This standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.  The fair value measurement disclosures are grouped into three levels based on valuation factors:

· Level 1 - quoted prices in active markets using identical assets

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

· Level 3 - significant unobservable inputs

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

	Fair Value Measurements
	(in thousands)
	March 31,
	2012		Level 1		Level 2		Level 3
Money market funds	$	146,842	$	146,842	$	-	$	-

Total	$	187,924	$	130,937	$	56,987	$	-

The municipal bond securities valued as Level 2 investments are primarily pre-refunded municipal bonds that are secured by escrow funds containing U.S. Government securities. Valuation techniques used by Insperity 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:

			Gross		Gross
	Amortized		Unrealized		Unrealized			Estimated
