Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 - Basis of Presentation of Interim Period Statements

The accompanying condensed consolidated financial statements are unaudited and have been prepared by Barrett Business Services, Inc. (“BBSI”, the “Company”, “our” or “we”), pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures typically included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from such estimates and assumptions. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2015 Annual Report on Form 10-K at pages F1 – F62. The results of operations for an interim period are not necessarily indicative of the results of operations for a full year.

Revenue recognition

We recognize professional employer (“PEO”) service and staffing service revenue as services are rendered by our workforce. PEO services are normally used by organizations to satisfy ongoing needs related to the management of human capital and are governed by the terms of a client services agreement which covers all employees at a particular work site. Our client services agreements have a minimum term of one year, are renewable on an annual basis and typically require 30 days’ written notice to cancel or terminate the contract by either party. In addition, our client services agreements provide for immediate termination upon any default of the client regardless of when notice is given.

We report PEO revenues on a net basis because we are not the primary obligor for the services provided by our clients to their customers pursuant to our client services agreements. We reduce these service fee revenues by the amounts invoiced to our clients for direct payroll expenses such as salaries, wages, health insurance, employee out-of-pocket expenses incurred incidental to employment, and safety incentives. Safety incentives represent cash incentives paid to certain client companies for maintaining safe-work practices and minimizing workplace injuries. The safety incentive is based on a percentage of annual payroll and is paid annually to clients who meet predetermined workers’ compensation claims cost objectives.

Cost of revenues

Our cost of revenues for staffing services includes direct payroll costs, employer payroll related taxes, employee benefits, and workers’ compensation costs. Our cost of revenues for PEO services includes only employer payroll related taxes and workers’ compensation costs. Direct payroll costs represent the gross payroll earned by staffing services employees based on salary or hourly wages. Payroll taxes and employee benefits consist of the employer’s portion of Social Security and Medicare taxes, federal and state unemployment taxes, and staffing services employee reimbursements for materials, supplies and other expenses, which are paid by our customer. Workers’ compensation costs consist primarily

Table of Contents

Note 1 - Basis of Presentation of Interim Period Statements (Continued)

of the costs associated with our workers’ compensation program, including claims reserves, claims administration fees, legal fees, medical cost containment (“MCC”) expense, state administrative agency fees, third-party broker commissions, risk manager payroll, and excess insurance premiums for catastrophic injuries. We maintain separate workers’ compensation insurance policies for employees working in states where the Company is not self-insured, including California.

Cash and cash equivalents

We consider non-restricted short-term investments, which are highly liquid, readily convertible into cash, and have maturities at acquisition of less than three months to be cash equivalents for purposes of the condensed consolidated statements of cash flows and condensed consolidated balance sheets. The Company maintains cash balances in bank accounts that normally exceed FDIC insured limits. The Company has not experienced any losses related to its cash concentration.

Investments

As of September 30, 2016, the Company’s investments consisted of municipal bonds and corporate bonds. We classify our investments as trading or available-for-sale. The Company had no trading securities at September 30, 2016 and December 31, 2015. The Company classifies money market funds, municipal bonds, and corporate bonds as available for sale. They are reported at fair value with unrealized gains and losses, net of taxes, shown as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Management considers available evidence in evaluating potential impairment of investments, including the duration and extent to which fair value is less than cost. Realized gains and losses on sales of investments are included in other income (expense) as other, net in our condensed consolidated statements of operations. In the event a loss is determined to be other-than-temporary, the loss will be recognized in the condensed consolidated statements of operations.

Restricted cash and investments

At September 30, 2016, restricted cash and investments consisted of money market funds, certificates of deposit, U.S. Treasuries, corporate bonds, and municipal bonds with maturities generally from 180 days to two years. At September 30, 2016, the approximate fair value of restricted cash and investments equaled their approximate amortized cost. Restricted investments have been categorized as available-for-sale. They are reported at fair value with unrealized gains and losses, net of taxes, shown as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Management considers available evidence in evaluating potential impairment of investments, including the duration and extent to which fair value is less than cost. Realized gains and losses on sales of restricted investments are included in other income (expense) as other, net in our condensed consolidated statements of operations. In the event a loss is determined to be other-than-temporary, the loss will be recognized in the condensed consolidated statements of operations.

Allowance for doubtful accounts

The Company had an allowance for doubtful accounts of $195,000 and $268,000 at September 30, 2016 and December 31, 2015, respectively. We make estimates of the collectability of our accounts receivable for services provided to our customers. Management analyzes historical bad debts, customer concentrations, customer credit-worthiness, current economic trends and changes in customers’ payment trends when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.

Workers’ compensation claims liabilities

Our workers’ compensation claims liabilities do not represent an exact calculation of liability but rather management’s best estimate, utilizing actuarial expertise and projection techniques, at a given reporting date. The estimated liability for open workers’ compensation claims is based on an evaluation of information provided by our internal claims adjusters and our third-party administrators for workers’ compensation claims, coupled with an actuarial estimate of future adverse cost development with respect to reported claims and incurred but not reported claims (together, “IBNR”). At September 30, 2016 and December 31, 2015, workers’ compensation claims liabilities included case reserve estimates for reported losses, plus additional amounts for estimated future adverse cost development of IBNR claims, MCC and legal costs, and unallocated loss adjustment expenses, including future administrative fees to be paid to third-party service providers. These estimates are reviewed at least quarterly and adjustments to estimated liabilities are reflected in current operating results as they become known.

The process of arriving at an estimate of unpaid claims and claims adjustment expense involves a high degree of judgment and is affected by both internal and external events, including changes in claims handling practices, changes in reserve estimation procedures, changes in individuals involved in the reserve estimation process, inflation, trends in the litigation and settlement of pending claims, and legislative changes.

Our estimates are based on informed judgment, derived from individual experience and expertise applied to multiple sets of data and analyses. We consider significant facts and circumstances known both at the time that loss reserves are initially established and as new facts and circumstances become known. Due to the inherent uncertainty underlying loss reserve estimates, the expenses incurred through final resolution of our liability for our workers’ compensation claims will likely vary from the related loss reserves at the reporting date. Therefore, as specific claims are paid out in the future, actual paid losses may be materially different from our current loss reserves.

The Company’s independent actuary provides management with an estimate of the current and long-term portions of our total workers’ compensation claims, which is an important factor in our process for estimating workers’ compensation claims liabilities. The current portion represents the independent actuary’s best estimate of payments the Company will make related to workers’ compensation claims over the ensuing twelve months. The Company will also pay out a portion of claims first incurred in the ensuing twelve months during that twelve-month period. The long-term portion represents the independent actuary’s best estimate of payments the Company will make related to workers’ compensation claims more than twelve months in the future.

A basic premise in most actuarial analyses is that historical data and past patterns demonstrated in the incurred and paid historical data form a reasonable basis upon which to project future outcomes, absent a material change. Significant structural changes to the available data can materially impact the reserve estimation process. To the extent a material change affecting the ultimate claim liability becomes known, such change is quantified to the extent possible through an analysis of internal Company data and, if available and when appropriate, external data. Nonetheless, actuaries exercise a considerable degree of judgment in the evaluation of these factors and the need for such actuarial judgment is more pronounced when faced with material uncertainties.

Safety incentives liability

Safety incentives represent cash incentives paid to certain PEO client companies for maintaining safe-work practices and minimizing workplace injuries. The incentive is based on a percentage of annual payroll and is paid annually to customers who meet predetermined workers’ compensation claims cost objectives. Safety incentive payments are made only after closure of all workers’ compensation claims incurred during the customer’s contract period. The safety incentive liability is estimated and accrued each month based upon contract year-to-date payroll and the then current amount of the customer’s estimated workers’ compensation claims reserves as established by us and our third-party administrator and the expected payout as determined by historical incentive payment trends. The Company provided $25.0 million and $21.3 million at September 30, 2016 and December 31, 2015, respectively, as an estimate of the liability for unpaid safety incentives. Safety incentive costs are netted against PEO service revenue in our condensed consolidated statements of operations.

Statements of cash flows

Interest paid during the nine months ended September 30, 2016 and 2015 did not materially differ from interest expense. Income taxes received during the nine months ended September 30, 2016 and 2015 totaled $1.1 million and $9.2 million, respectively.

Basic and diluted earnings per share

Basic earnings per share are computed based on the weighted average number of common shares outstanding for each year using the treasury method. Diluted earnings per share reflect the potential effects of the exercise of stock options and the payment of stock awards from other share-based compensation plans that are outstanding at the end of each period presented. Basic and diluted shares outstanding are summarized as follows (in thousands):

Accounting estimates

The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Estimates are used for fair value measurement of all investments, allowance for doubtful accounts, deferred income taxes, carrying values for goodwill and property and equipment, accrued workers’ compensation liabilities and safety incentive liabilities. Actual results may differ from such estimates.

Recent accounting pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The amendments in ASU 2014-09 provide for a single, principles-based model for revenue recognition that replaces the existing revenue recognition guidance. In August 2015, the FASB issued ASU 2015-14 which defers the effective date of ASU 2014-09 by one year. ASU 2014-09 is discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. In March and April 2016, the FASB issued ASU 2016-08 Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Identifying Performance Obligations and Licensing, ASU 2016-11 Revenue Recognition and Derivatives and Hedging: Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, and ASU 2016-12 Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients, which all provide further clarification to be considered when implementing ASU 2014-09. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted as of the date of the original effective date, for interim and annual reporting periods beginning after December 15, 2016. The Company plans to adopt this ASU on January 1, 2018 and is in the process of evaluating its planned transition method and the impact to its consolidated financial statements and disclosures of the adoption of ASU 2014-09.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03, Interest—Imputation of Interest (“ASU 2015-03”) to simplify the presentation of debt issuance costs. ASU 2015-03 requires debt issuance costs be presented on the balance sheet as a direct reduction from the carrying amount of the related debt liability. The amendments in this accounting standard update are to be applied retrospectively and are effective for interim and annual reporting periods beginning after December 15, 2015. We do not expect the adoption of this accounting standard update to have a material impact on our consolidated financial statements and disclosures.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (“ASU 2015-07”). ASU 2015-07 provides that investments for which the practical expedient is used to measure fair value at net asset value per share (“NAV”) must be removed from the fair value hierarchy. Instead, those investments must be included as a reconciling line item so that the total fair value amount of investments in the disclosure is consistent with the amount on the balance sheet. ASU 2015-07 also includes disclosure requirements for investments for which the NAV practical expedient was used to determine fair value. The adoption of this guidance in the third quarter of 2016 did not impact our financial condition or results of operations.

In November 2015, the FASB issued Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The guidance becomes effective for the Company beginning with our annual report for the year ending December 31, 2017 with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires a lessee to record a right of use asset and a corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. ASU 2016-02 is effective for all interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is in the process of evaluating the impact of ASU 2016-02 on the Company’s consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for the taxes related to stock-based compensation, including adjustments to how excess tax benefits and a company’s payments for tax withholdings should be classified. This guidance will be effective for fiscal years beginning after December 15, 2016. The Company is currently evaluating the impact that ASU 2016-09 will have on its consolidated financial statements and disclosures.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments.” ASU No. 2016-15 clarifies and provides specific guidance on eight cash flow classification issues that are not currently addressed by current GAAP, thereby reducing the current diversity in practice. ASU No. 2016-15 is effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2017, with early application permitted. This guidance is applicable to the Company’s fiscal year beginning January 1, 2018. The Company is in the process of evaluating the impact of adoption of ASU 2016-15 to the presentation of consolidated cash flows.

Note 3 - Workers’ Compensation Claims

The following table summarizes the aggregate workers’ compensation reserve activity (in thousands):

The states of California, Maryland, Oregon, Washington, Colorado and Delaware required us to maintain specified investment balances or other financial instruments totaling $159.0 million at September 30, 2016 to cover potential workers’ compensation claims losses related to the Company’s current and former status as a self-insured employer. In addition to restricted cash and investments held to satisfy these requirements at September 30, 2016, we have provided surety bonds and standby letters of credit totaling $152.9 million, including a California requirement of $147.2 million.

The Company also operates a wholly owned insurance company, Ecole Insurance Company (“Ecole”). Ecole is a fully licensed insurance company holding a certificate of authority from the Arizona Department of Insurance. Ecole provides workers’ compensation coverage to the Company’s employees working in Arizona, Utah and Nevada. The surplus of Ecole was $10.8 million and $9.5 million at September 30, 2016 and December 31, 2015, respectively, and is included in long-term restricted cash and investments in our condensed consolidated balance sheets.

As part of its fronted workers’ compensation insurance program with Chubb Limited (“Chubb”, formerly ACE Group) in the states of California, Delaware, Virginia, Pennsylvania, North Carolina, New Jersey, West Virginia and the District of Columbia, the Company makes payments into a trust account (“the Chubb trust account”) to be used for the payment of future claims. The balance in the Chubb trust account was $235.2 million and $166.6 million at September 30, 2016 and December 31, 2015, respectively. The Chubb trust account balances are included as a component of the current and long-term restricted cash and investments in the Company’s condensed consolidated balance sheets.

Note 3 - Workers’ Compensation Claims (Continued)

At September 30, 2016 the Company recorded an asset of $13.2 million related to a payment remitted to Chubb on September 29, 2016 but not deposited into the Chubb trust account until October 2016. This amount is included in other assets in the condensed consolidated balance sheet.

Note 4 - Revolving Credit Facility and Long-Term Debt

The Company maintains a credit agreement (the “Agreement”) with its principal bank, Wells Fargo Bank, National Association (the “Bank”). The Agreement provided for a $40.0 million term loan maturing December 31, 2016, as well as a $14.0 million revolving credit line, with a $6.0 million sublimit for unsecured standby letters of credit. As of September 30, 2016, the term loan has been paid off completely, compared to an outstanding balance of $15.0 million at December 31, 2015.

The Agreement also included $42.3 million in cash-secured letters of credit at September 30, 2016 to satisfy collateral requirements associated with the Company’s former status as a self-insured employer in California. In conjunction with these letters of credit, the Company posted with the Bank as collateral $44.1 million in restricted money market funds and restricted certificates of deposit.

Advances under the revolving credit facility bear interest as selected by the Company of either (a) a daily floating rate of one month LIBOR plus 2.0% or (b) a fixed rate of LIBOR plus 2.0%. The Agreement also provides for an unused commitment fee of 0.35% per year on the average daily unused amount of the revolving credit facility, and a fee of 1.75% of the face amount of each letter of credit. The Company had no outstanding borrowings on its revolving credit line at September 30, 2016 and December 31, 2015. The revolving credit line expires on October 1, 2017.

The credit facility is collateralized by the Company’s accounts receivable and other rights to receive payment, general intangibles and equipment.

The Agreement requires the satisfaction of certain financial covenants as follows:

The Agreement includes certain additional restrictions as follows:

Table of Contents

Note 4 - Revolving Credit Facility and Long-Term Debt (Continued)

The Agreement also contains customary events of default. If an event of default under the Agreement occurs and is continuing, the Bank may declare any outstanding obligations under the Agreement to be immediately due and payable.

At September 30, 2016, the Company was in violation of the capital expenditure restriction. The Bank agreed to waive this covenant violation.

The Company maintains a mortgage loan with the Bank with a balance of approximately $4.7 million and $4.8 million at September 30, 2016 and December 31, 2015, respectively, secured by the Company’s corporate office building in Vancouver, Washington. This loan requires payment of monthly principal payments of $18,375 plus interest at a rate of one month LIBOR plus 2.25%, with the unpaid principal balance due November 1, 2017.

Note 5 - Income Taxes

Under ASC 740, “Income Taxes,” management evaluates the realizability of the deferred tax assets on a quarterly basis under a “more-likely than not” standard. As part of this evaluation, management reviews all evidence both positive and negative to determine if a valuation allowance is needed. One component of this analysis is to determine whether the Company was in a cumulative loss position for the most recent 12 quarters. The Company was in a cumulative income position for the 12 quarters ended September 30, 2016. Based on management’s analysis, no valuation allowance of deferred tax assets was recorded at September 30, 2016.

The Internal Revenue Service is examining the Company’s federal tax returns for the years ended December 31, 2011, 2012, 2013 and 2014.

Note 6 - Litigation

On November 6, 2014, plaintiffs in Michael Arciaga, et al. v. Barrett Business Services, Inc., et al., filed an action in the United States District Court for the Western District of Washington against BBSI, Michael L. Elich, BBSI’s Chief Executive Officer, and James D. Miller, BBSI’s then Chief Financial Officer. The action purported to be a class action brought on behalf of all BBSI shareholders alleging violations of the federal securities laws. The claims arose from the decline in the market price for BBSI common stock following announcement of a charge for increased workers’ compensation reserves expense. The lawsuit sought compensatory damages, plus interest, and costs and expenses (including attorney fees and expert fees).

On November 13, 2014, a second purported shareholder class action was filed in the United States District Court for the Western District of Washington, entitled Christopher P. Carnes, et al. v. Barrett Business Services, Inc., et al. The Carnes complaint named the same defendants as the Arciaga case and asserted similar claims for relief.

Similarly, on November 17, 2014, a third purported shareholder class action was filed in the United States District Court for the Western District of Washington, entitled Shiva Stein, et al. v. Barrett Business Services, Inc., et al. The Stein complaint named the same defendants as the Arciaga and Carnes cases and asserted similar claims for relief.

On February 25, 2015, the court ordered consolidation of the three cases, and any new or other cases involving the same subject matter, into a single action for pretrial purposes. The consolidated cases were recaptioned as In re Barrett Business Services Securities Litigation. The court also appointed the Painters & Allied Trades District Council No. 35 Pension and Annuity Funds as the lead plaintiff.

On March 21, 2016, before the court had ruled on the defendants’ motion to dismiss the plaintiffs’ first amended consolidated complaint, the plaintiffs filed a second amended consolidated complaint, naming the same defendants. The second amended consolidated complaint dropped certain allegations from the first amended complaint and added new allegations relating to disclosures in BBSI’s Current Report on Form 8-K filed on March 9, 2016. The defendants filed a motion to dismiss the second amended consolidated complaint on May 23, 2016.

On October 26, 2016, before the court ruled on the motion to dismiss, the parties entered into a Stipulation and Agreement of Settlement dated as of October 26, 2016 (the “Settlement”), to settle the litigation. The settlement class includes all persons and entities who purchased or otherwise acquired BBSI common stock in the period beginning February 12, 2013, through March 9, 2016, and were damaged thereby, with certain exclusions.

The Settlement is intended to fully, finally and forever compromise, settle, release, resolve, and dismiss with prejudice the purported class action and all claims asserted therein against the named defendants. In the Settlement, the defendants have denied all allegations of wrongdoing and the plaintiffs have not conceded any infirmities in their positions.

Note 6 – Litigation (Continued)

The Settlement calls for the payment in cash of $12.0 million (the “Settlement Fund”) into escrow by November 29, 2016, which is 15 business days after the court entered an order preliminarily approving the Settlement. Of this amount, approximately $8.7 million will be paid by BBSI’s insurance carriers and approximately $3.3 million will be paid by BBSI. The amount to be paid by BBSI has been accrued at September 30, 2016 and is included in other accrued liabilities in our condensed consolidated balance sheet. The fees of counsel for the plaintiffs will be paid out of the Settlement Fund following approval by the court.

The Settlement is subject to approval by the court and to other customary terms and conditions, including the right of BBSI to terminate the Settlement under specified circumstances. All potential class members will be notified of the Settlement in November 2016. The court has scheduled a hearing for February 22, 2017, to consider final approval of the Settlement. If the Settlement is not approved by the court, or is otherwise terminated before it is finalized, BBSI is unable to predict the final outcome of the litigation or to estimate its effect on BBSI, which may be material and adverse.

BBSI received a subpoena from the San Francisco office of the Division of Enforcement of the Securities and Exchange Commission (the “SEC”) in May 2015 in connection with the SEC’s investigation of BBSI’s accounting practices with regard to its workers’ compensation reserves. In April 2016, the SEC issued a second subpoena to BBSI for documents relating to the disclosures made by BBSI following Mr. Miller’s termination. BBSI was also advised by the United States Department of Justice in mid-June 2016 that it has commenced an investigation. BBSI is cooperating fully with the investigations.

On June 17, 2015, Daniel Salinas (“Salinas”) filed a shareholder derivative lawsuit against BBSI and certain of its officers and directors in the Circuit Court for Baltimore City, Maryland. The complaint alleges breaches of fiduciary duty, unjust enrichment and other violations of law and seeks recovery of various damages, including the costs and expenses incurred in connection with BBSI’s reserve strengthening process, reserve study and consultants, the cost of stock repurchases by BBSI in October 2014, compensation paid to BBSI’s officers, and costs of negotiating BBSI’s credit facility with its principal lender, as well as the proceeds of sales of stock by certain of BBSI’s officers and directors during 2013 and 2014. On September 28, 2015, BBSI and the individual defendants filed motions to dismiss the derivative suit and a motion to stay pending resolution of In re Barrett Business Services Securities Litigation. On December 4, 2015, Salinas filed an opposition to each motion. On January 27, 2016, the defendants filed a reply to the opposition brief. On February 11, 2016, Judge Michel Pierson heard oral argument on the motions. A decision has not been issued.

Management is unable to estimate the probability, or the potential range of loss arising from the legal actions described above.

General

Company Background. Barrett Business Services, Inc. (“BBSI,” the “Company,” “our” or “we”), is a leading provider of business management solutions for small and mid-sized companies. The Company has developed a management platform that integrates a knowledge-based approach from the management consulting industry with tools from the human resource outsourcing industry. This platform, through the effective leveraging of human capital, helps our business owner clients run their businesses more effectively. We believe this platform, delivered through a decentralized organizational structure, differentiates BBSI from our competitors. BBSI was incorporated in Maryland in 1965.

Business Strategy. Our strategy is to align local operations teams with the mission of small and mid-sized business owners, driving value to their business. To do so, BBSI:

Business Organization. We operate a decentralized delivery model using operationally-focused business teams, typically located within 50 miles of our client companies. These teams are led by senior level business generalists and comprise senior level professionals with expertise in human resources, organizational development, risk mitigation and workplace safety and various types of administration, including payroll. These teams are responsible for growth of their operations and for providing strategic leadership, guidance and expert consultation to our client companies. The decentralized structure fosters autonomous decision-making in which business teams deliver plans that closely align with the objectives of each business owner client. This structure also provides a means of incubating talent to support increased growth and capacity. We support clients with employees located in 22 states and the District of Columbia through a network of 55 branch locations in California, Oregon, Washington, Arizona, Colorado, Idaho, Nevada, Utah, Delaware, Maryland, North Carolina and Virginia. We also have several smaller recruiting locations in our general market areas, which are under the direction of a branch office.

BBSI believes that making significant investments in the best talent available allows us to leverage the value of this investment many times over. We motivate our management employees through a compensation package that includes a competitive base salary and the opportunity for profit sharing. At the branch level, profit sharing is in direct correlation to client performance, reinforcing a culture focused on achievement of client goals.

Services Overview. BBSI’s core purpose is to advocate for business owners, particularly in the small and mid-sized business segment. Our evolution from an entrepreneurially run company to a professionally managed organization has helped inform our view that all businesses experience inflection points at key stages of growth. The insights gained through our own growth, along with the trends we see in working with more than 4,100 companies each day, define our approach to guiding business owners through the challenges associated with being an employer. BBSI’s business teams align with each business owner client through a structured three-tiered progression. In doing so, business teams focus on the objectives of each business owner and deliver planning, guidance and resources in support of those objectives.

Tier 1: Tactical Alignment

The first stage focuses on the mutual setting of expectations and is essential to a successful client relationship. It begins with a process of assessment and discovery in which the business owner’s business objectives, attitudes, and culture are aligned with BBSI’s processes, controls and culture. This stage includes an implementation process, which addresses the administrative components of employment.

Tier 2: Dynamic Relationship

The second stage of the relationship emphasizes organizational development as a means of achieving each client’s business objectives. There is a focus on process improvement, development of best practices, supervisor training and leadership development.

Tier 3: Strategic Counsel

With an emphasis on advocacy on behalf of the business owner, the third stage of the relationship is more strategic and forward-looking with a goal of cultivating an environment in which all efforts are directed by the mission and long-term objectives of the business owner.

In addition to serving as a resource and guide, BBSI has the ability to provide workers’ compensation coverage as a means of meeting statutory requirements and protecting our clients from employment-related injury claims. Through our internal claims managers and our third-party administrators, we provide claims management services for our clients. We work aggressively to manage and reduce job injury claims, identify fraudulent claims and structure optimal work programs, including modified duty.

Results of Operations

The following table sets forth the percentages of total revenues represented by selected items in the Company’s Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2016 and 2015.

We report professional employer service revenues on a net basis because we are not the primary obligor for the services provided by our co-employed clients to their customers pursuant to our client service agreements. We present for comparison purposes the gross revenues and cost of revenues information for the three and nine months ended September 30, 2016 and 2015 in the table below. Although not in accordance with GAAP, management believes this information is informative as to the level of our business activity and illustrative of how we manage our operations, including the preparation of our internal operating forecasts, because it presents our professional employer services on a basis comparable to our staffing services.

The presentation of revenues on a net basis and the relative contributions of staffing and professional employer services revenues can create volatility in our gross margin percentage. The general impact of fluctuations in our revenue mix is described below.
