Basis of Presentation

(1)	Basis of Presentation

The accompanying unaudited consolidated financial statements of Universal Logistics Holdings, Inc. and its wholly-owned subsidiaries (collectively, “Universal” or the “Company”) have been prepared by the Company’s management. In the opinion of management, the unaudited consolidated financial statements include all normal recurring adjustments necessary to present fairly the information required to be set forth therein. All intercompany transactions and balances have been eliminated in consolidation. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted from these statements pursuant to such rules and regulations and, accordingly, should be read in conjunction with the consolidated financial statements as of December 31, 2018 and 2017 and for each of the years in the three-year period ended December 31, 2018 included in the Company’s Form 10-K filed with the Securities and Exchange Commission. The preparation of the consolidated financial statements requires the use of management’s estimates. Actual results could differ from those estimates.

Our fiscal year ends on December 31 and consists of four quarters, each with thirteen weeks.

The Company made certain immaterial reclassifications to items in its prior financial statements so that their presentation is consistent with the format in the financial statements for the period ended June 29, 2019. These reclassifications, however, had no effect on reported consolidated net income, comprehensive income, earnings per common share, cash flows, total assets or shareholders’ equity as previously reported.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases. The objective of the new standard is to establish principles for lessees and lessors to report information about the amount, timing, and uncertainty of cash flows arising from a lease. The ASU requires a lessee to recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of 12 months or less, the lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In July 2018, the FASB issued additional authoritative guidance providing companies with the option to apply this ASU to new and existing leases within the scope of the guidance as of the beginning of the period of adoption. We elected this transition method of applying the new lease standard on January 1, 2019. In doing so, we also elected the package of practical expedients provided under the guidance, however; we did not elect the hindsight practical expedient when determining the lease term for existing leases. The practical expedient package applies to leases that commenced prior to adoption of the new standard and permits companies not to reassess whether existing or expired contracts are or contain a lease, the lease classification, and any initial direct costs. Upon adoption of the standard, we recorded offsetting lease assets and lease liabilities, resulting in a $88.8 million increase in total assets, a $26.0 million increase in total current liabilities and a $62.8 million increase in total long-term liabilities in our consolidated balance sheet. The amount of accrued rent as of adoption was not material. Prior period amounts were not adjusted and are reported under the accounting standards in effect for those periods. The adoption of the standard did not have a material impact on our results of operations or cash flows. See Note 9 for additional information pertaining to leases.

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which amends existing guidance for reporting comprehensive income to reflect changes resulting from the Tax Cuts and Jobs Act of 2017. The amendment provides the option to reclassify stranded tax effects within accumulated other comprehensive income (AOCI) to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Act is recorded. The adoption of this standard did not have a material impact on our financial condition, results of operations, or cash flows.

In June 2016, the FASB issued ASU 2016-13, (“ASU 2016-13”), Accounting for Credit Losses (Topic 326). ASU 2016-13 requires the use of an “expected loss” model on certain types of financial instruments. The standard also amends the impairment model for available-for-sale debt securities and requires estimated credit losses to be recorded as allowances instead of reductions to amortized cost of the securities. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, with early adoption permitted. The Company is evaluating the new guidance, but does not expect it to have a material impact on its financial condition, results of operations, or cash flows.

Revenue Recognition [Abstract]

Revenue Recognition

(3)	Revenue Recognition

The Company broadly groups its services into the following categories: truckload services, brokerage services, intermodal services, dedicated services and value-added services. We disaggregate these categories and report our service lines separately on the Consolidated Statements of Income.

Truckload services include dry van, flatbed, heavy-haul and refrigerated operations. We transport a wide variety of general commodities, including automotive parts, machinery, building materials, paper, food, consumer goods, furniture, steel and other metals on behalf of customers in various industries.

To complement our available capacity, we provide customers freight brokerage services by utilizing third-party transportation providers to move freight. Brokerage services also include full service domestic and international freight forwarding, and customs brokerage.

Intermodal services include rail-truck, steamship-truck and support services. Our intermodal support services are primarily short-to-medium distance delivery of rail and steamship containers between the railhead or port and the customer and drayage services.

Dedicated services are primarily provided in support of automotive and retail customers using van equipment. Dedicated services also include our final mile and ground expedited services. Our dedicated services are primarily short run or round-trip moves within a defined geographic area.

Transportation services are short-term in nature; agreements governing their provision generally have a term of less than one year. They do not contain significant financing components. The Company recognizes revenue over the period transportation services are provided to the customer, including service performed as of the end of the reporting period for loads currently in-transit, in order to recognize the value that is transferred to a customer over the course of the transportation service.

We determine revenue in-transit using the input method, under which revenue is recognized based on the duration of time that has lapsed from the departure date (start of transportation services) to the arrival date (completion of transportation services). Measurement of revenue in-transit requires the application of significant judgment. We calculate the estimated percentage of an order’s transit time that is complete at period end, and we apply that percentage of completion to the order’s estimated revenue.

Value-added services, which are typically dedicated to individual customer requirements, include material handling, consolidation, sequencing, sub-assembly, cross-dock services, kitting, repacking, warehousing and returnable container management. Value-added revenues are substantially driven by the level of demand for outsourced logistics services. Major factors that affect value-added service revenue includes changes in manufacturing supply chain requirements and production levels in specific industries, particularly the North American automotive and Class-8 heavy-truck industries.

Revenue is recognized as control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration the Company expects to receive in exchange for its services. We have elected to use the “right to invoice” practical expedient to recognize revenue, reflecting that a customer obtains the benefit associated with value-added services as they are provided. The contracts in our value-added services businesses are negotiated agreements, which contain both fixed and variable components. The variability of revenues is driven by volumes and transactions, which are known as of an invoice date. Value-added service contracts typically have terms that extend beyond one year, and they do not include financing components.

The following table provides information related to contract balances associated with our contracts with customers (in thousands):

We generally receive payment for performance obligations within 45 days of completion of transportation services and 65 days for completion of value-added services. Contract assets in the table above generally relate to revenue in-transit at the end of the reporting period.

Marketable Securities

(4)	Marketable Securities

The Company accounts for its marketable equity securities in accordance with ASC Topic 321 “Investments- Equity Securities.” ASC Topic 321 requires companies to measure equity investments at fair value, with changes in fair value recognized in net income. The Company’s investments in marketable securities consist of equity securities with readily determinable fair values. The cost of securities sold is based on the specific identification method, and interest and dividends on securities are included in non-operating income (expense).

Marketable equity securities are carried at fair value, with gains and losses in fair market value included in the determination of net income. The fair value of marketable equity securities is determined based on quoted market prices in active markets, as described in Note 8.

The following table sets forth market value, cost, and unrealized gains on equity securities (in thousands):

	June 29, 2019		December 31, 2018
Fair value	$	9,646	$	9,333
Cost		8,890		11,143
Unrealized gain (loss)	$	756	$	(1,810	)

During the thirteen-week and twenty-six week periods ended June 29, 2019, our marketable equity securities portfolio experienced a net unrealized pre-tax gain (loss) in market value of approximately $(119,000) and $756,000, respectively, which was reported in other non-operating income (expense) for the period.

During the thirteen-week and twenty-six week periods ended June 30, 2018, our marketable equity securities portfolio experienced a net unrealized pre-tax gain (loss) in market value of approximately $214,000 and $(433,000), respectively, which was reported in other non-operating income (expense) for the period.

On April 22, 2019, the Company acquired Michael’s Cartage, Inc. (“Michael’s”). Headquartered in Bridgeview, Illinois, Michael’s provides intermodal drayage services to customers primarily within a 300-mile radius of the Chicagoland area. The total cash purchase price was $22.0 million, subject to post-closing adjustments. The Company used available cash and borrowings on its revolving credit facility to finance the acquisition, and is in the process of finalizing the purchase accounting for this transaction. Approximately $0.4 million of transaction related costs were incurred in the acquisition.

The Company accounted for the acquisition in accordance with ASC 805 “Business Combinations.” Assets acquired and liabilities assumed were recorded at their estimated fair value at acquisition, with the remaining unallocated purchase price recorded as goodwill. The goodwill recorded is included in our transportation segment, and is deductible for income tax purposes. The Company is in the process of finalizing post-closing purchase price adjustments and valuations related to certain assets and liabilities. The preliminary allocation of the purchase price is as follows (in thousands):

(1) The Credit and Security Agreement (the “Credit Agreement”) provides for maximum borrowings of $350 million in the form of a $150 million term loan and a $200 million revolver. Term loan proceeds were advanced on November 27, 2018 and mature on November 26, 2023. The term loan will be repaid in consecutive quarterly installments, as defined in the Credit Agreement, commencing March 31, 2019, with the remaining balance due at maturity. Borrowings under the revolving credit facility may be made until and mature on November 26, 2023. Borrowings under the Credit Agreement bear interest at LIBOR or a base rate, plus an applicable margin for each based the Company’s leverage ratio. The Credit Agreement is secured by a first priority pledge of the capital stock of applicable subsidiaries, as well as first priority perfected security interest in cash, deposits, accounts receivable, and selected other assets of the applicable borrowers. The Credit Agreement includes customary affirmative and negative covenants and events of default, as well as financial covenants requiring minimum fixed charge coverage and leverage ratios, and customary mandatory prepayments provisions. At June 29, 2019, we were in compliance with all covenants under the facility, and $147.0 million was available for borrowing on the revolver.

(2) The Equipment Financing consists of a series of promissory notes issued by a wholly-owned subsidiary in order to finance transportation equipment. The equipment notes, which are secured by liens on selected titled vehicles, include certain affirmative and negative covenants and are generally payable in 60 monthly installments and bear interest at fixed rates ranging from 3.18% to 5.13%. At June 29, 2019, we were in compliance with all covenants.

(3) The Real Estate Financing consists of a series of promissory notes issued by a wholly-owned subsidiary in order to finance certain real property. The promissory notes, which are secured by first mortgages and assignment of leases on specific parcels of real estate and improvements, include certain affirmative and negative covenants and are generally payable in 120 monthly installments. Each of the notes bears interest at LIBOR plus 2.25%. At June 29, 2019, we were in compliance with all covenants.

(4) The Margin Facility is a short-term line of credit secured by our portfolio of marketable securities. It bears interest at LIBOR plus 1.10%. The amount available under the line of credit is based on a percentage of the market value of the underlying securities. At June 29, 2019, the maximum available borrowings under the line of credit were $5.3 million.

The Company is also party to two interest rate swap agreements that qualify for hedge accounting. The swap agreements were executed to fix a portion of the interest rates on its variable rate debt that have a combined notional amount of $15.7 million at June 29, 2019. Under the swap agreements, the Company receives interest at the one-month LIBOR rate plus 2.25%, and pays a fixed rate. The March 2016 swap (swap A) became effective October 2016, has a rate of 4.16% (amortizing notional amount of $10.0 million) and expires July 2026, and an additional March 2016 swap (swap B) became effective October 2016, has a rate of 3.83% (amortizing notional amount of $5.7 million) and expires May 2022. At June 29, 2019, the fair value of the swap agreements was a liability of $0.1 million. Since these swap agreements qualify for hedge accounting, the changes in fair value are recorded in other comprehensive income (loss), net of tax. See Note 9 for additional information pertaining to interest rate swaps.

Fair Value Disclosures [Abstract]

Fair Value Measurements and Disclosures

(9)	Fair Value Measurements and Disclosures

FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date and expanded disclosures with respect to fair value measurements.

FASB ASC Topic 820 also establishes a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:

•

Level 1 — Quoted prices in active markets for identical assets or liabilities.

•

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.

(9)	Fair Value Measurements and Disclosures – continued

We have segregated all financial assets and liabilities that are measured at fair value on a recurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the tables below (in thousands):

	June 29, 2019

Interest rate swaps		—		392		—		392
Total	$	9,333	$	392	$	—	$	9,725

The valuation techniques used to measure fair value for the items in the tables above are as follows:

•

Cash equivalents – This category consists of money market funds which are listed as Level 1 assets and measured at fair value based on quoted prices for identical instruments in active markets.

•

Marketable securities – Marketable securities represent equity securities, which consist of common and preferred stocks, are actively traded on public exchanges and are listed as Level 1 assets. Fair value was measured based on quoted prices for these securities in active markets.

•

Interest rate swaps – The fair value of our interest rate swaps, as provided by a third party service provider, is determined using a methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash receipts (or payments) are based on the expectation of future interest rates (forward curves) derived from observed market interest rate curves. The fair value measurement also incorporates credit valuation adjustments to appropriately reflect both the Company’s nonperformance risk and the respective counterparty’s nonperformance risk.

Our revolving credit and term loan agreements and our real estate promissory notes consist of variable rate borrowings. We categorize borrowings under these credit agreements as Level 2 in the fair value hierarchy. The carrying value of these borrowings approximate fair value because the applicable interest rates are adjusted frequently based on short-term market rates.

For our equipment promissory notes, the fair values are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. We categorize borrowings under this credit agreement as Level 2 in the fair value hierarchy. The carrying value and estimated fair value of these promissory notes at June 29, 2019 is summarized as follows:

Leases

Leases [Abstract]

Leases

(10)Leases

On January 1, 2019, we adopted ASU 2016-02, Leases, which required us to recognize a right-of-use asset and a corresponding lease liability on our balance sheet for most leases classified as operating leases under previous guidance. Right-of-use assets represent our right to use an underlying asset over the lease term and lease liabilities represent the obligation to make lease payments resulting from the lease agreement. We recognize a right-of-use asset and a lease liability on the effective date of a lease agreement.

We initially record these assets and liabilities based on the present value of lease payments over the lease term using our incremental borrowing rate applicable to the leased asset or the implicit rate in the lease if it is readily determinable. Most of our leases did not provide a readily determinable implicit rate, and therefore we estimated our incremental borrowing rate based on information available at lease commencement. The incremental borrowing rate is defined as the rate of interest that we would have to pay to borrow, on a collateralized basis and over a similar term, an amount equal to the lease payments in a similar economic environment. We elected to utilize a portfolio approach and applied the rates to a portfolio of leases with similar underlying assets and terms. Upon adoption of the new lease standard, discount rates used for existing leases were established at January 1, 2019. ASU 2016-02 was adopted as of the effective date, and as such prior period amounts are reported under the accounting standards in effect for those periods.

As of June 29, 2019, our obligations under operating lease arrangements primarily related to the rental of office space, warehouses, freight distribution centers, terminal yards and equipment. Our lease obligations typically do not include options to purchase the leased property, nor do they contain residual value guarantees or material restrictive covenants. Options to extend or terminate an agreement are included in the lease term when it becomes reasonably certain the option will be exercised. As of June 29, 2019, we were not reasonably certain of exercising any renewal or termination options, and as such, no adjustments were made to the right-of-use lease assets or corresponding liabilities.

We did not separate lease and nonlease components of contracts for purposes of determining the right-of use lease asset and corresponding liability. Variable lease components that do not depend on an index or a rate, and variable nonlease components were also not contemplated in the calculation of the right-of-use asset and corresponding liability. For facility leases, variable lease costs include the costs of common area maintenance, taxes, and insurance for which we pay the lessors an estimate that is adjusted to actual expense on a quarterly or annual basis depending on the underlying contract terms. For equipment leases, variable lease costs may include additional fees associated with using equipment in excess of estimated amounts. Leases with an initial term of 12 months or less, short-term leases, are not recorded on the balance sheet. Lease expense for short-term and long-term operating leases is recognized on a straight-line basis over the lease term.

In connection with our transportation services, we also pay tolls and other fees for international bridge crossings to certain related entities which are under common control with CenTra.

(11)	Transactions with Affiliates – continued

A significant number of our operating locations are located in facilities leased from affiliates. At 36 facilities, occupancy is based on either month-to-month or contractual, multi-year lease arrangements which are billed and paid monthly. Leasing properties provided by an affiliate that owns a substantial commercial property portfolio affords us significant operating flexibility; however, we are not limited to such arrangements.

We purchase workers’ compensation, property and casualty, cargo, warehousing and other general liability insurance from an insurance company controlled by our majority shareholders. Our employee health care benefits and 401(k) programs are also provided by this affiliate.

Other services from affiliates, including contracted transportation services, are delivered to us on a per-transaction-basis or pursuant to separate contractual arrangements provided in the ordinary course of business. At June 29, 2019 and December 31, 2018, amounts due to affiliates were $17.0 million and $17.8 million, respectively. In our Consolidated Balance Sheets, we record our insured claims liability and the related recovery from an affiliate insurance provider in insurance and claims, and other receivables. At June 29, 2019 and December 31, 2018, there were $9.8 million and $10.5 million, respectively, included in each of these accounts for insured claims.

We made purchases of used equipment from an affiliate during the twenty-six weeks ended June 30, 2018 totaling $8,300, and purchased wheels and tires from an affiliate for new trailering equipment totaling $23,000 during the same period. There were no such purchases made during the twenty-six weeks ended June 29, 2019.

Stock Based Compensation

(12)	Stock Based Compensation

On April 23, 2014, our Board of Directors adopted the 2014 Amended and Restated Stock Incentive Plan, or the Plan. The Plan was approved by our shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The Plan replaced our 2004 Stock Incentive Plan and carried forward the shares of common stock that remained available for issuance under the 2004 Stock Incentive Plan. The grants may be made in the form of stock options, restricted stock bonuses, restricted stock purchase rights, stock appreciation rights, phantom stock units, restricted stock units or unrestricted common stock. Restricted stock awards currently outstanding under the 2004 Stock Incentive Plan will remain outstanding in accordance with the terms of that plan.

On February 22, 2017 and February 24, 2016, the Company granted 10,000 and 10,000 shares, respectively, of restricted stock to our Chief Executive Officer. The restricted stock grants have fair values of $13.45 per share and $15.55 per share, respectively, based on the closing price of the Company’s stock on each grant date. For each award, 25% of the shares vested immediately on the grant dates, and the remaining shares vest in three equal installments with the final vesting of the 2017 award to occur on March 5, 2020, in each case subject to continued employment with the Company.

On February 20, 2019, the Company granted 44,500 shares of restricted stock to certain of its employees, including 12,000 shares to our Chief Executive Officer and 10,000 shares to our Chief Financial Officer. The restricted stock grants have a grant date fair value of $23.56 per share, based on the closing price of the Company’s stock, and will vest in four equal increments on each February 20 in 2020, 2021, 2022 and 2023, in each case subject to continued employment with the Company.

A grantee’s vesting of restricted stock awards may be accelerated under certain conditions, including retirement.

In the twenty-six week periods ended June 29, 2019 and June 30, 2018, the total grant date fair value of vested shares recognized as compensation costs was $0.1 million and $0.2 million, respectively. As of June 29, 2019, there was approximately $1.2 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized on a straight-line basis over the remaining vesting period. As a result, the Company expects to recognize stock-based compensation expense of $0.3 million in each year of 2020, 2021, 2022 and 2023.

We report our financial results in two reportable segments, the transportation segment and the logistics segment, based on the nature of the underlying customer commitment and the types of investments required to support these commitments. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria.

Operations aggregated in our transportation segment are associated with individual freight shipments coordinated by our agents, company-managed terminals and specialized services operations. In contrast, operations aggregated in our logistics segment deliver value-added services or transportation services to specific customers on a dedicated basis, generally pursuant to contract terms of one year or longer. Other non-reportable operating segments are comprised of the Company’s subsidiaries that provide support services to other subsidiaries and to owner-operators, including shop maintenance and equipment leasing.

The following tables summarize information about our reportable segments as of and for the thirteen week and twenty-six week periods ended June 29, 2019 and June 30, 2018 (in thousands):

Our principal commitments relate to long-term real estate leases and payment obligations to equipment vendors.

On October 16, 2017, a jury in state court in Cook County, Illinois rendered a verdict of $54.2 million against Universal Am-Can, Ltd. (“UACL”) in the matter of Denton v. UACL, et al. The litigation relates to a vehicular accident that occurred on February 8, 2011 on I-65 in Rensselaer, Indiana. The accident involved a tractor-trailer being driven by an independent owner-operator of UACL. The driver was braking on the expressway in order to avoid another vehicle being driven the wrong way on the interstate. The truck attempted to avoid the oncoming vehicle and the plaintiff’s vehicle and, in so doing, struck the plaintiff’s vehicle. As a result of the accident, the plaintiff sustained non-life threatening injuries. In connection with the verdict, the jury determined that UACL was responsible for the liability associated with the accident. The verdict included $19.2 million in compensatory damages and $35.0 million in punitive damages against UACL. Interest on the verdict accrues at a rate of 9% per year. The insurance coverage available for reimbursement of UACL’s damages underlying the verdict is limited to $1.0 million. We believe the facts and the law do not support the jury’s findings of liability against UACL. The Company has filed an appeal with the Appellate Court of Illinois First Judicial District to overturn the verdict and the judgment. Enforcement of the judgment has been stayed pending the outcome of the appeal. The Company currently estimates the possible range of financial exposure in the matter, net of insurance coverage and before advances made to plaintiffs, to be between $18.2 and $53.2 million. Based on the Company’s best estimate of the liability at this time, the Company recorded an accrued liability for this matter of $18.2 million, which is inclusive of any interest accruing and before consideration of advances made. In September 2018, the Company made a $7.0 million advance, the amount of which will be used as an offset against the ultimate resolution. As such, this amount was recorded as a reduction of the Company’s accrued liability. While we cannot predict with any certainty the outcome of this litigation, its ultimate resolution could be significantly different from our estimate and materially affect our financial condition, results of operations and cash flows.

The Company was plaintiff in a lawsuit that was filed on June 11, 2015 against, among others, Dalton Logistics, Inc. (“Dalton”) in the United States District Court for the Southern District of Texas. The Company was seeking approximately $1.9 million in damages from a debtor relating to unpaid freight charges. In response to the filing of the complaint, the shareholders of Dalton filed a counterclaim against the Company alleging that the Company, in connection with certain unrelated negotiations with the defendant, breached an alleged agreement to acquire Dalton. The respective claims proceeded to trial and, on July 21, 2017, a jury returned two separate verdicts: One in favor of Universal for $1.9 million, and a second in favor of the defendant for approximately $5.7 million. On October 30, 2017, the court entered a judgment against Universal for the $5.7 million, but ignored the $1.9 million jury award in favor of Universal. The Company has filed an appeal with the United States Court of Appeals for the Fifth Circuit to overturn the verdict and the judgment. Enforcement of the judgment has been stayed pending the outcome of the appeal. The Company currently estimates the possible range of financial exposure in the matter to be between $0 and $5.7 million. Based on the Company’s best estimate of the liability at this time, the Company has recorded an accrued liability for this matter of $1.8 million. While we cannot predict with any certainty the outcome of this litigation, management does not believe the outcome will have a material adverse effect on our business, financial condition, results of operations or cash flows.

The Company is involved in certain other claims and pending litigation arising from the ordinary conduct of business. We also provide accruals for claims within our self-insured retention amounts. Based on the knowledge of the facts, and in certain cases, opinions of outside counsel, in the Company’s opinion the resolution of these claims and pending litigation will not have a material effect on our financial position, results of operations or cash flows. However, if we experience claims that are not covered by our insurance or that exceed our estimated claim reserve, it could increase the volatility of our earnings and have a materially adverse effect on our financial condition, results of operations or cash flows.

At June 29, 2019, approximately 27% of our employees in the United States, Canada and Colombia, and 87% of our employees in Mexico are subject to collective bargaining agreements that are renegotiated periodically, less than 10% of which are subject to contracts that expire in 2019.

On July 25, 2019, our Board of Directors declared Universal’s second quarter cash dividend of $0.105 per share of common stock, payable to shareholders of record at the close of business on August 5, 2019 and expected to be paid on August 12, 2019. The Board also declared that Universal’s third quarter cash dividend of $0.105 per share is payable on October 1, 2019 to shareholders of record on September 2, 2019. Declaration of future cash dividends is subject to final determination by the Board of Directors each quarter after its review of our financial condition, results of operations, capital requirements, any legal or contractual restrictions on the payment of dividends and other factors the Board of Directors deems relevant.

On August 2, 2019, our Board of Directors authorized the repurchase of up to 300,000 shares of our common stock through a “Dutch auction” tender offer. Subject to certain limitations and legal requirements, we could repurchase up to an additional 2% of our outstanding shares. The tender offer began on the date of the announcement, August 5, 2019 and will expire on September 3, 2019. Through this tender offer, the Company’s shareholders will have the opportunity to tender some or all of their shares at a price within the range of $21.00 to $24.00 per share. The Company anticipates using available cash and cash equivalents and from funds borrowed under its revolving credit facility to pay for the shares tendered.
