Equity Transactions

Secondary offering

On May 13, 2016, the Company priced a secondary offering of 1,700,000 shares of the Company’s common stock (the “Firm Shares”). Each share was sold at an offering price of $26.25 per share. The shares sold were registered under the Securities Act of 1933, as amended (the “Securities Act”), on an effective registration statement on Form S-3 (Registration No. 333-206644) pursuant to the Securities Act. In addition, the Company granted the underwriters of this secondary offering a 30-day option to purchase an additional 255,000 shares (the “Option Shares”) of common stock to cover over-allotments. On May 18, 2016, the Company closed on the Firm Shares, for which we received net proceeds of approximately $41,000 after deducting the underwriting discount and estimated offering expenses payable by the Company and issued 1,700,000 shares. On June 3, 2016, the Company closed on the full exercise of the Option Shares by the underwriters of the secondary offering with respect to an additional 255,000 shares of its common stock, for which we received net proceeds of approximately $6,200 after deducting the underwriters’ discount.

Warrant exercise

In conjunction with the Company’s initial public offering on March 26, 2013, the underwriter received a warrant to acquire up to 140,000 units at an exercise price of $7.80 per unit (“Unit Warrant”).  Each of these units consisted of one share of the Company’s common stock and one warrant to purchase one share of the Company’s common stock at an exercise price of $7.80 per share, which warrant expires on March 27, 2018. On March 23, 2016, the underwriter paid $1,008 to the Company to initiate the exercise of the Unit Warrant.  On March 29, 2016, the Company delivered 140,000 shares of common stock to the underwriter, and, on May 5, 2016, the Company completed the exercise of the Unit Warrant by delivery of the warrant. 

Note 2 - Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements of the Company are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting of interim financial information. Pursuant to such rules and regulations, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted. The consolidated financial statements include the accounts of NV5 Global, Inc. and those of its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.

In the opinion of management, the accompanying unaudited interim consolidated financial statements of the Company contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the financial position and results of operations of the Company as of the dates and for the periods presented. Accordingly, these statements should be read in conjunction with the financial statements and notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The accompanying consolidated balance sheet as of December 31, 2015 has been derived from those financial statements. The results of operations and cash flows for the interim periods presented are not necessarily indicative of the results to be expected for any future interim period or for the full 2016 fiscal year.

 Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. These estimates and assumptions are based on management’s most recent assessment of underlying facts and circumstances using the most recent information available. Actual results could differ significantly from these estimates and assumptions, and the differences could be material.

Estimates and assumptions are evaluated periodically and adjusted when necessary. The more significant estimates affecting amounts reported in the consolidated financial statements relate to the fair value estimates used in accounting for business combinations including the valuation of identifiable intangible assets and contingent consideration, fair value estimates in determining the fair value of its reporting units for goodwill impairment assessment, revenue recognition on the percentage-of-completion method, allowances for uncollectible accounts and provision for income taxes.

Concentration of Credit Risk

 Trade receivable balances carried by the Company are comprised of accounts from a diverse client base across a broad range of industries and are not collateralized. However, approximately 25% and 47% of the Company’s gross revenues for the six months ended June 30, 2016 and 2015, respectively, are from California-based projects. The Company does not have any client representing more than 10% of gross revenues during the six months ended June 30, 2016. The Company had one client representing 12% of gross revenues for the six months ended June 30, 2015. Approximately 50% and 63% of the Company’s accounts receivable as of June 30, 2016 and December 31, 2015, respectively, are from government and government-related contracts. Management continually evaluates the creditworthiness of these and future clients and provides for bad debt reserves as necessary.

Fair Value of Financial Instruments

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels of valuation hierarchy are defined as follows:

Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The Company considers cash and cash equivalents, accounts receivable, accounts payable, income taxes payable, accrued liabilities and debt obligations to meet the definition of financial instruments. As of June 30, 2016 and December 31, 2015, the carrying amount of cash and cash equivalents, accounts receivable, accounts payable, income taxes payable and accrued liabilities approximate their fair value due to the relatively short period of time between their origination and their expected realization or payment. The carrying amounts of debt obligations approximate their fair values as the terms are comparable to terms currently offered by local lending institutions for arrangements with similar terms to industry peers with comparable credit characteristics.

The Company applies the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations, in the accounting for its acquisitions, which requires recognition of the assets acquired and the liabilities assumed at their acquisition date fair values, separately from goodwill. Goodwill as of the acquisition date is measured as the excess of consideration transferred and the net of the acquisition date fair values of the tangible and identifiable intangible assets acquired and liabilities assumed. The allocation of the purchase price to identifiable intangible assets (customer relationships, customer backlog, trade name and non-compete) is based on valuations performed to determine the fair values of such assets as of the acquisition dates. The Company engaged a third-party independent valuation specialist to assist in the determination of fair values of tangible and intangible assets acquired and liabilities assumed for the 2016 and 2015 acquisitions. The fair values of earn-out arrangements are included as part of the purchase price of the acquired companies on their respective acquisition dates.  The Company estimates the fair value of contingent earn-out payments as part of the initial purchase price and records the estimated fair value of contingent consideration as a liability on the consolidated balance sheet. Changes in the estimated fair value of contingent earn-out payments are included in General and Administrative expenses on the Consolidated Statements of Net Income and Comprehensive Income.

Several factors are considered when determining contingent earn-out liabilities as part of the purchase price, including whether (i) the valuation of the acquisitions is not supported solely by the initial consideration paid, and the contingent earn-out formula is a critical and material component of the valuation approach to determining the purchase price; and (ii) the former owners of the acquired companies that remain as key employees receive compensation other than contingent earn-out payments at a reasonable level compared with the compensation of other key employees.  The contingent earn-out payments are not affected by employment termination.

We review and re-assess the estimated fair value of contingent consideration on a quarterly basis, and the updated fair value could differ materially from the initial estimates.  Adjustments to the estimated fair value related to changes in all other unobservable inputs are reported in operating income.

The Company measures contingent consideration liabilities recognized in connection with business combinations at fair value on a recurring basis using significant unobservable inputs classified within Level 3, as defined in the accounting guidance. The Company uses a probability-weighted discounted cash flow approach as a valuation technique to determine the fair value of the contingent consideration on the acquisition date and at each reporting period. The significant unobservable inputs used in the fair value measurements are projections over the earn-out period, and the probability outcome percentages that are assigned to each scenario. Significant increases or decreases to either of these inputs in isolation could result in a significantly higher or lower liability with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate on the acquisition date and amount paid will be recorded in earnings (see Note 10).

Goodwill and Intangible Assets 

Goodwill is the excess of consideration paid for an acquired entity over the amounts assigned to assets acquired, including other identifiable intangible assets and liabilities assumed in a business combination. To determine the amount of goodwill resulting from a business combination, the Company performs an assessment to determine the acquisition date fair value of the acquired company’s tangible and identifiable intangible assets and liabilities.

Goodwill is required to be evaluated for impairment on an annual basis or whenever events or changes in circumstances indicate the asset may be impaired. An entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. These qualitative factors include: macroeconomic and industry conditions, cost factors, overall financial performance and other relevant entity-specific events. If the entity determines that this threshold is met, then performing the two-step quantitative impairment test is unnecessary. The two-step impairment test requires a comparison of the carrying value of the assets and liabilities associated with a reporting unit, including goodwill, with the fair value of the reporting unit. The Company determines fair value through multiple valuation techniques, and weights the results accordingly. NV5 Global is required to make certain subjective and complex judgments in assessing whether an event of impairment of goodwill has occurred, including assumptions and estimates used to determine the fair value of its reporting units. If the carrying value of a reporting unit exceeds the fair value of the reporting unit, the Company would calculate the implied fair value of its reporting unit goodwill as compared to the carrying value of its reporting unit goodwill to determine the appropriate impairment charge, if any. The Company has elected to perform its annual goodwill impairment review on August 1 of each year. The Company historically conducts its annual impairment tests on the goodwill using the quantitative method of evaluating goodwill.

Identifiable intangible assets primarily include customer backlog, customer relationships, trade names and non-compete agreements. Amortizable intangible assets are amortized on a straight-line basis over their estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that the assets may be impaired. If an indicator of impairment exists, the Company compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then impairment, if any, is measured as the difference between fair value and carrying value, with fair value typically based on a discounted cash flow model.

See Note 7 for further information on goodwill and identified intangibles.

Earnings Per Share

Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the Company. In accordance with the FASB ASC 260, Earnings per Share, the effect of potentially dilutive securities is not considered during periods of loss or if the effect is anti-dilutive. The weighted average number of shares outstanding in calculating basic earnings per share for the three and six months ended June 30, 2016 and 2015 exclude 495,042 and 779,431 non-vested restricted shares, respectively, issued since 2010. These non-vested restricted shares are not included in basic earnings per share until the vesting requirement is met. The weighted average number of shares outstanding in calculating diluted earnings per share for the three and six months ended June 30, 2016 and 2015 includes, if outstanding, non-vested restricted shares and units, issuable shares related to acquisitions, and the shares and warrants associated with the Company’s initial public offering. In calculating diluted earnings per share for the three and six months ended June 30, 2016 and 2015, there were no potentially anti-dilutive securities.

The following table represents a reconciliation of the net income and weighted average shares outstanding for the calculation of basic and diluted earnings per share for the three and six months ended June 30, 2016 and 2015:

Note 3 – Recent Accounting Pronouncements

In March 2016, FASB issued Accounting Standards Update 2016-09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-09 and have not yet determined its impact on our consolidated financial statements.

In February 2016, FASB issued ASU 2016-02, Leases. ASU 2016-02 requires lessees to recognize, in the balance sheet, a liability to make lease payments and a right-of-use asset representing the right to use the underlying asset over the lease term. The amendments in this accounting standard update are to be applied using a modified retrospective approach and are effective for fiscal years beginning after December 15, 2018. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our consolidated financial statements.

In November 2015, FASB issued ASU 2015-17— Balance Sheet Classification of Deferred Taxes. As part of FASB's accounting simplification initiative, ASU 2015-17 removes the requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. Instead, the update requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for entities for fiscal years beginning after December 15, 2016, with prospective or retrospective application to all periods presented. Early application is permitted. The Company does not expect the impact of this ASU to be material to its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This ASU was originally effective for annual reporting periods beginning after December 15, 2016 and early adoption is permitted as of the original effective date. Companies may use either a full retrospective or a modified retrospective approach to adopt this ASU and management has not yet determined which method it will apply. In July 2015, FASB voted to approve a one-year deferral of the effective date to December 31, 2017 for interim and annual reporting periods beginning after that date and permitted early adoption of the standard, but not before the original effective date of December 15, 2016. As a result, ASU 2014-09 will become effective for us in the first quarter of our fiscal year ending December 31, 2018. The Company is currently evaluating the impact of adopting ASU 2014-09 on the Company's consolidated net income, financial position and cash flows.

Note 4 – Business Acquisitions

On May 20, 2016, the Company acquired Dade Moeller & Associates, Inc., a North Carolina corporation ("Dade Moeller"). Dade Moeller provides professional services in radiation protection, health physics, and worker safety to government and commercial facilities.  Dade Moeller's technical expertise includes radiation protection, industrial hygiene and safety, environmental services and laboratory consulting.  This acquisition expanded the Company’s environmental, health and safety services and allows the Company to offer these services on a broader scale within its existing network. The purchase price of this acquisition was $20,000 including $10,000 in cash, $6,000 in promissory notes (bearing interest at 3.5%), payable in four installments of $1,500, due on the first, second, third and fourth anniversaries of May 20, 2016, the effective date of the acquisition (see Note 9), $1,000 of the Company’s common stock (36,261 shares) as of the closing date of the acquisition, and $3,000 in stock or a combination of cash and shares of the Company’s stock, at our discretion, payable in three installments of $1,000, due on the first, second and third anniversaries of May 20, 2016. In order to ultimately determine the fair values of tangible and intangible assets acquired and liabilities assumed for Dade Moeller, we engaged a third-party independent valuation specialist to assist in the determination of fair values of tangible and intangible assets acquired and liabilities, however as of the date of this report, the valuation was not final. We expect to finalize the purchase price allocation with respect to this transaction by the end of the third quarter of 2016.

On February 1, 2016, the Company acquired Sebesta, Inc. (“Sebesta”), a St. Paul, Minnesota-based mechanical, electrical and plumbing (“MEP”) engineering and energy management company. Primary clients include federal and state governments, power and utility companies, and major educational, healthcare, industrial and commercial property owners throughout the United States. The purchase price of this acquisition was $14,000 paid from cash on hand. This acquisition expanded the Company’s MEP engineering and energy and allows the Company to offer these services on a broader scale within its existing network. In addition, this acquisition strengthens the Company’s geographic diversification and allows the Company to continue expanding its national footprint. In order to ultimately determine the fair values of tangible and intangible assets acquired and liabilities assumed for Sebesta, we engaged a third-party independent valuation specialist to assist in the determination of fair values of tangible and intangible assets acquired and liabilities, which we finalized during the second quarter of 2016.

On June 24, 2015, the Company acquired certain assets of Allwyn, an environmental services firm based in Phoenix, AZ, that specializes in environmental assessment, radon mitigation, NEPA planning and permitting, NQA-1 compliance, geotechnical engineering, construction materials testing and inspection, and water resources projects. The purchase price of up to $1,300 included up to $800 in cash and a $500 promissory note (bearing interest at 3.5%), payable in three installments of $167, due on the first, second and third anniversaries of June 24, 2015, the effective date of the acquisition (see Note 9). 

On April 22, 2015, the Company acquired all of the outstanding equity interests of Mendoza, a San Francisco based program management firm, with seven offices throughout California, that specializes in the provision of construction program consulting services to public and private clients in the transportation and clean water/wastewater industries. The purchase price of up to $4,000 included up to $500 in cash, a $3,000 short-term promissory note, based on the collection of acquired accounts receivable and work in process, payable within one year, and a $500 promissory note (bearing interest at 3%), payable in two installments of $250, due on the first and second anniversaries of April 22, 2015, the effective date of the acquisition (see Note 9).

On January 30, 2015, the Company acquired all of the outstanding equity interests of Joslin, Lesser & Associates, Inc. (“JLA”), a program management and owner’s representation consulting firm that primarily services government owned facilities and public K through 12 school districts in the Boston, MA area. The purchase price of up to $5,500 included $2,250 in cash, a $1,250 promissory note (bearing interest at 3.5%), payable in four installments of $313, due on the first, second, third, and fourth anniversaries of January 30, 2015, the effective date of the acquisition (see Note 9), and $1,000 of the Company’s common stock (89,968 shares) as of the closing date of the acquisition. The purchase price also included a non-interest bearing earn-out of up to $1,000 payable in cash, notes and the Company’s common stock, subject to the achievement of certain agreed upon metrics for calendar year 2015. The earn-out of $1,000 is non-interest bearing and was recorded at its estimated fair value of $901, based on a probability-weighted approach valuation technique used to determine the fair value of the contingent consideration on the acquisition date. The note and the earn-out are due to a related party individual. As of June 30, 2016 and December 31, 2015, this contingent consideration was $375 and $500, respectively.

The following table summarizes the fair values of the assets acquired and liabilities assumed as of the acquisition date for the acquisitions closed during 2016 and final fair values of the assets acquired and liabilities assumed as of the acquisition dates for the acquisitions closed during 2015:

Goodwill was recorded based on the amount by which the purchase price exceeded the fair value of the net assets acquired and the amount is attributable to the reputation of the business acquired, the workforce in place and the synergies to be achieved from these acquisitions. The goodwill acquired during the six months ended June 30, 2016 was assigned to the PM reportable segment. Goodwill of approximately $15,199 is expected to be deductible for income tax purposes for the 2016 acquisitions.  

The consolidated financial statements of the Company for the three and six months ended June 30, 2016 include the results of operations from the businesses acquired during 2016 from its date of acquisition to June 30, 2016. For the three and six months ended June 30, 2016, the results include gross revenues of $9,662 and $15,117, respectively, and pre-tax income of approximately $1,021 and $1,452, respectively. The consolidated financial statements of the Company for the three and six months ended June 30, 2015 include the results of operations from the businesses acquired during 2015 from their respective dates of acquisition to June 30, 2015. For the three and six months ended June 30, 2015, the results include gross revenues of approximately $3,634 and $2,327, respectively and pre-tax income of $1,514 and $1,088, respectively. Included in general and administrative expense for the three and six months ended June 30, 2016 is $178 and $431, respectively, of acquisition-related costs pertaining to the Company’s acquisition activities.

The following table presents the unaudited, pro forma consolidated results of operations (in thousands, except per share amounts) for the three and six months ended June 30, 2016 and 2015 as if the RBA, Sebesta and Dade Moeller acquisitions had occurred as of January 1, 2015. The pro forma information provided below is compiled from the financial statements of these acquisitions and includes pro forma adjustments for amortization expense, reduction in certain expenses and the income tax impact of these adjustments. The pro forma results are not necessarily indicative of (i) the results of operations that would have occurred had these acquisitions operations actually been acquired on January 1, 2015; or (ii) future results of operations:

Note 5 – Accounts Receivable, net

Accounts receivable, net, consists of the following:

Billed accounts receivable represents amounts billed to clients that remain uncollected as of the balance sheet date. Unbilled accounts receivable represents recognized amounts pending billing pursuant to contract terms or accounts billed after period end, and are expected to be billed and collected within the next 12 months.

Note 6 – Property and Equipment, net

Property and equipment, net, consists of the following:

Depreciation expense was $414 and $162 for the three months ended June 30, 2016 and 2015, respectively, and $792 and $313 for the six months ended June 30, 2016 and 2015, respectively.

Note 7 – Goodwill and Intangible Assets

Goodwill

On August 1, 2015, the Company conducted its annual impairment tests using the quantitative method of evaluating goodwill. Based on the quantitative analyses the Company determined the fair value of each of the reporting units exceeded its carrying value. Therefore, the goodwill was not impaired and the Company did not recognize an impairment charge relating to goodwill as of August 1, 2015. There were no indicators, events or changes in circumstances that would indicate goodwill was impaired during the period from August 2, 2015 through June 30, 2016.

The table set forth below shows the change in goodwill during the six months ended June 30, 2016:

Intangible Assets

Intangible assets, net, as of June 30, 2016 and December 31, 2015 consist of the following:

Trade names are amortized on a straight-line basis over their estimated lives ranging from 1 to 3 years. Customer backlog and customer relationships are amortized on a straight-lines basis over estimated lives ranging from 1 to 9 years. Non-compete agreements are amortized on a straight-line basis over their contractual lives ranging from 4 to 5 years. Favorable lease is amortized on a straight-line basis over the remaining lease term of 9 years.

Amortization expense was $1,025 and $597 for the three months ended June 30, 2016 and 2015, respectively, and $1,889 and $1,086 for the six months ended June 30, 2016 and 2015, respectively.

 Credit Facility

On January 31, 2014, the Company entered into a Business Loan Agreement with Western Alliance Bank, an Arizona corporation (“Western Alliance”), as lender, which was amended on September 3, 2014 and provides for a two-year, $8,000 revolving credit facility (the “Credit Facility”). The interest rate is prime rate plus 0.50%, with a minimum of 3.75%, which was the interest rate as of June 30, 2016. The Credit Facility contains certain financial covenants, including an annual maximum debt to tangible net worth ratio of 3.0:1.0 as of December 31, 2014 and for each annual period ending on the last day of each fiscal year thereafter. In addition, the Credit Facility contains an annual minimum debt service coverage ratio equal to 1.5:1.0 for each annual period ending on the last day of the fiscal year beginning December 31, 2013. The Credit Facility also contains financial reporting covenant provisions and other covenants, representations, warranties, indemnities, and events of default that are customary for facilities of this type. The Credit Facility is guaranteed by the Company’s wholly-owned subsidiaries: (i) NV5 Holdings, (ii) NV5, Inc., (iii) NV5, LLC, (iv) JLA, and (v) The RBA Group, Inc. Engineers, Architects and Planners (“RBA”). As of June 30, 2016 and December 31, 2015, the Company is in compliance with the financial and reporting covenants.

Note 10 – Contingent Consideration

The following table summarizes the changes in the carrying value of estimated contingent consideration:

Note 11 – Commitments and Contingencies

Litigation, Claims and Assessments

The Company is subject to certain claims and lawsuits typically filed against the engineering, consulting and construction profession, alleging primarily professional errors or omissions. The Company carries professional liability insurance, subject to certain deductibles and policy limits, against such claims. However, in some actions, parties are seeking damages that exceed our insurance coverage or for which we are not insured. While management does not believe that the resolution of these claims will have a material adverse effect, individually or in aggregate, on its financial position, results of operations or cash flows, management acknowledges the uncertainty surrounding the ultimate resolution of these matters.

The Company’s office leases are classified as operating leases and rent expense is included in facilities and facilities related expense in the Company’s consolidated statements of net income and comprehensive income. Some lease terms include rent and other concessions and rent escalation clauses which are included in computing minimum lease payments. Minimum lease payments are recognized on a straight-line basis over the minimum lease term. The variance of rent expense recognized from the amounts contractually due pursuant to the underlying leases is included in accrued liabilities in the Company’s consolidated balance sheets.

Note 12 – Stock-Based Compensation

In October 2011, the Company’s stockholders approved the 2011 Equity Incentive Plan, which was subsequently amended and restated in March 2013 (as amended, the “2011 Equity Plan”). The 2011 Equity Plan provides directors, executive officers, and other employees of the Company with additional incentives by allowing them to acquire ownership interest in the business and, as a result, encouraging them to contribute to the Company’s success. The Company may provide these incentives through the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares and units, and other cash-based or stock-based awards. As of June 30, 2016, 495,042 shares of common stock are authorized and reserved for issuance under the 2011 Equity Plan. This reserve automatically increases on each January 1 from 2014 through 2023, by an amount equal to the smaller of (i) 3.5% of the number of shares issued and outstanding on the immediately preceding December 31, or (ii) an amount determined by the Company’s Board of Directors. The restricted shares of common stock granted generally provide for service-based vesting after two to four years following the grant date. A summary of the changes in unvested shares of the restricted stock during the year ended June 30, 2016 is presented below.

The following table summarizes the status of restricted stock awards as of June 30, 2016 and December 31, 2015, and changes during 2016:

Share-based compensation expense relating to restricted stock awards during the three months ended June 30, 2016 and 2015 was $550 and $388, respectively, and for the six months ended June 30, 2016 and 2015 was $1,049 and $666, respectively. Approximately $5,279 of deferred compensation, which is expected to be recognized over the remaining weighted average vesting period of 2.4 years, is unrecognized at June 30, 2016.

Note 13 – Income Taxes

As of June 30, 2016 and December 31, 2015, the Company had net current deferred income tax assets of $1,440 and non-current deferred tax liabilities of $1,634 and $1,582, respectively. No valuation allowance against the Company’s net deferred income tax assets is needed as of June 30, 2016 and December 31, 2015 as it is more-likely-than-not that the positions will be realized upon settlement. Deferred income tax liabilities primarily relate to intangible assets and accounting basis adjustments where the Company has a future obligation for tax purposes. During the three and six months ended June 30, 2016, the Company did not record any deferred tax assets or liabilities in conjunction with the purchase price allocation of acquisitions as a result of the intangibles acquired.

The Company’s consolidated effective income tax rate was 36.7% and 36.8% for the three and six months ended June 30, 2016, respectively. The Company’s consolidated effective income tax rate was 36.5% and 36.6% for the three and six months ended June 30, 2015, respectively. The difference between the effective income tax rate and the combined statutory federal and state income tax rate of approximately 39.0% is principally due to the federal domestic production activities deduction.

The Company evaluates tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. The California Franchise Tax Board (“CFTB”) is challenging the use of certain research and development tax credits generated and included on the tax returns of an acquired company for the years 2005 to 2009. Fiscal years 2005 through 2015 are considered open tax years in the State of California and 2012 through 2015 in the U.S. federal jurisdiction and other state jurisdictions.

 At June 30, 2016 and December 31, 2015, the Company had $570 of unrecognized tax benefits. Included in the balance of unrecognized tax benefits at June 30, 2016 and December 31, 2015 were $570 of tax benefits that, if recognized, would affect our effective tax rate. It is not expected that there will be a significant change in the unrecognized tax benefits in the next 12 months.

Note 14 – Reportable Segments

The Company reports segment information in accordance with ASC Topic No. 280 "Segment Reporting" ("Topic No. 280"). As of June 30, 2016, the Company continues to report based on the following reportable segments:

Infrastructure, engineering and support services (INF): The INF reportable segment provides to clients a broad array of services in the area of engineering, design and support services; and energy services.

Construction quality assurance (CQA): The CQA reportable segment provides construction inspection; geotechnical and engineering services; construction claims and litigation services; and environmental quality testing services.

Program management services (PM): The PM reportable segment provides program management for transportation and vertical construction projects including construction management. Also currently included in PM are 2016 acquisitions of Sebesta and Dade Moeller.

        The Company evaluates the performance of these reportable segments based on their respective operating income before the effect of amortization expense related to acquisitions and other unallocated corporate expenses. We account for inter-segment revenues and transfers as if the sales and transfers were to third parties. All significant intercompany balances and transactions are eliminated in consolidation.

The following tables set forth summarized financial information concerning our reportable segments. Prior period segment financial information presented has been recast to reflect the reporting structure as evaluated during the fourth quarter of 2015:
