Marketable Securities

Marketable Securities

At June 29, 2013 and December 31, 2012, marketable securities, all of which are available-for-sale, consist of common and preferred stocks. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive income, except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in other non-operating income (expense), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in other non-operating income (expense).

The cost, gross unrealized holding gains, gross unrealized holding losses, and fair value of available-for-sale securities by type were as follows (in thousands):


	Cost		Gross unrealized holding gains		Gross unrealized holding (losses)			Fair Value
At June 29, 2013 Equity Securities	$	7,701	$	2,765	$	(217	)	$	10,249

At December 31, 2012 Equity Securities	$	8,106	$	2,077	$	(221	)	$	9,962

Included in equity securities at June 29, 2013 are securities with a fair value of $1.2 million with a cumulative loss position of $0.2 million, the impairment of which the Company considers to be temporary. The Company considers several factors in its determination as to whether declines in value are judged to be temporary or other-than-temporary, including the severity and duration of the decline, the financial condition and near-term prospects of the specific issuers and the industries in which they operate, and the Company’s intent and ability to hold these securities. The Company may incur future impairment charges if declines in market values continue and/or worsen and impairments are no longer considered temporary.

The fair value and gross unrealized holding losses of the Company’s marketable securities that are not deemed to be other-than-temporarily impaired aggregated by type and length of time they have been in a continuous unrealized loss position were as follows (in thousands):


	Less than 12 Months				12 Months or Greater				Total
	Fair Value		Unrealized Losses		Fair Value		Unrealized Losses		Fair Value		Unrealized Losses
At June 29, 2013 Equity securities	$	1,014	$	78	$	212	$	139	$	1,226	$	217

At December 31, 2012 Equity securities	$	1,222	$	118	$	164	$	103	$	1,386	$	221

The Company’s portfolio of equity securities in a continuous loss position, the impairment of which the Company considers to be temporary, consists primarily of common stocks in the oil and gas, banking, transportation and diversified holding industries. The fair value and unrealized losses are distributed in 10 publicly traded companies, with no single industry or company representing a material or concentrated unrealized loss. The Company has evaluated the near-term prospects of the various industries, as well as the specific issuers within its portfolio, in relation to the severity and duration of the impairments, and based on that evaluation, and the Company’s ability and intent to hold these investments for a reasonable period of time to allow for a recovery of fair value, the Company does not consider these investments to be other-than-temporarily impaired at June 29, 2013.

The Company from time to time invests cash in excess of its current needs in marketable securities, much of which is held in equity securities, which are actively traded on public exchanges. It is the philosophy of the Company to minimize the risk of capital loss without foregoing the potential for capital appreciation through investing in value-and-income oriented investments. However, holding equity securities subjects the Company to fluctuations in the market value of its investment portfolio based on current market prices, and a decline in market prices or other unstable market conditions could cause a loss in the value of the Company’s marketable securities classified as available-for-sale.

Syndicated credit facility

On August 30, 2012, the Company entered into a Revolving Credit and Term Loan Agreement, or the Credit Agreement, with and among the lenders parties thereto and Comerica Bank, as administrative agent, to provide for aggregate borrowing facilities of up to $220 million. The Credit Agreement consists of a $110 million revolving credit facility (which amount may be increased by up to $20 million upon request of the Company and approval of the lenders), a $60 million equipment credit facility, and a $50 million term loan. Additionally, the Credit Agreement provides for up to $5 million in letters of credit, which letters of credit reduce availability under the revolving credit facility.

Upon closing the merger with LINC on October 1, 2012, we borrowed approximately $149.1 million to repay LINC’s outstanding indebtedness and dividends payable via the Credit Agreement.

$110 million Revolving Credit Facility

The revolving credit facility is available to refinance existing indebtedness and to finance working capital through August 28, 2017. Two interest rate options are applicable to advances borrowed pursuant to the facility: Eurodollar-based advances and base rate advances. Eurodollar-based advances bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin, which varies from 1.35% to 2.10% based on our ratio of total debt to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as defined. As an alternative, base rate advances bear interest at a base rate, as defined, plus an applicable margin, which also varies based on our ratio of total debt to EBITDA in a range from 0.35% to 1.10%. The base rate is the greater of the prime rate announced by Comerica Bank, the federal funds effective rate plus 1.0%, or the daily adjusting LIBOR rate plus 1.0%. At June 29, 2013, interest accrued at 1.80% based on 30-day LIBOR.

To support daily borrowing and other operating requirements, the revolving credit facility contains a $10.0 million Swing Line sub-facility and a $5.0 million letter of credit sub-facility. On June 3, 2013, the Company executed an amendment to its Revolving Credit and Term Loan Agreement (the “First Amendment”), which split the availability on the Swing Line between two existing lenders, Comerica Bank and KeyBank. The SwingLine was split to provide for borrowings of up to $7.0 million from Comerica Bank and $3.0 million from KeyBank, so long as the Comerica Bank and KeyBank advances do not exceed $10.0 million in the aggregate. Swing Line borrowings incur interest at either the base rate plus the applicable margin or, alternatively, at a quoted rate offered by the applicable Swing Line lender in its sole discretion. The Company did not have any amounts outstanding under the Swing Lines at June 29, 2013, and there were no letters of credit issued against the lines.

The revolving credit facility is subject to a facility fee, which is payable quarterly in arrears, of either 0.25% or 0.5%, depending on our ratio of total debt to EBITDA. Other than in connection with Eurodollar-based advances or quoted rate advances that are paid off and terminated prior to an applicable interest period, there are no premiums or penalties resulting from prepayment. Borrowings outstanding at any time under the revolving credit facility are limited to the value of eligible accounts receivable of our principal operating subsidiaries, pursuant to a monthly borrowing base certificate. At June 29, 2013, our $46.0 million revolver advance was secured by, among other assets, net eligible accounts receivable totaling $101.0 million, of which, $82.9 million were available for borrowing against pursuant to the agreement.

$60 million Equipment Credit Facility

The equipment credit facility is available to refinance existing indebtedness and to finance capital expenditures including in connection with acquisitions. Borrowings under the equipment credit facility may be made until August 28, 2015, and such borrowings shall be repaid in quarterly installments equal to 1/28^th of the aggregate amount of borrowings under the equipment credit facility commencing on January 1, 2014.

The two interest rate options that apply to revolving credit facility advances also apply to equipment credit facility advances. Eurodollar-based advances bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin, which varies from 1.60% to 2.60% based on our ratio of total debt to EBITDA. Base rate advances bear interest at a base rate, as defined, plus an applicable margin, which also varies based on our ratio of total debt to EBITDA in a range from 0.60% to 1.60%. The equipment credit facility is subject to an unused fee, which is payable quarterly in arrears, of 0.5%. At June 29, 2013, interest accrued at 2.05% based on 30-day LIBOR.

$50 million Term Loan

Proceeds of the term loan were advanced on October 1, 2012 and used to refinance existing indebtedness of LINC. The outstanding principal balance is due on August 28, 2017, to the extent not already reduced by mandatory or optional prepayments. The applicable interest rate on the effective date of the term loan indebtedness was the base rate. Base rate advances bear interest at a defined base rate plus an applicable margin which varies from 1.50% to 2.25%, based on our ratio of total debt to EBITDA. Thereafter, we may convert base rate advances to Eurodollar-based advances, which bear interest at 30, 60 or 90-day LIBOR rates plus an applicable margin which varies from 2.50% to 3.25%, based on our ratio of total debt to EBITDA. At June 29, 2013, interest accrued at 2.95% based on 30-day LIBOR.

Interest on the unpaid principal of all term loan base rate advances is payable quarterly in arrears commencing on October 1, 2012, and on the first day of each October, January, April and July thereafter. Interest on the unpaid principal of each Eurodollar-based advance of the term loan is payable on the last day of the applicable Eurodollar interest period.

The Credit Agreement requires the Company to repay the borrowings made under the term loan facility and the equipment credit facility as follows: 50% (which percentage shall be reduced to 0% subject to the Company attaining a certain leverage ratio) of the Company’s annual excess cash flow, as defined; 100% of net cash proceeds of certain asset sales; and 100% of certain insurance and condemnation proceeds. Mandatory prepayment of the term loan was $0 as of June 29, 2013. The Company may voluntarily repay outstanding loans under each of the facilities at any time, subject to certain customary “breakage” costs with respect to LIBOR-based borrowings. In addition, the Company may elect to permanently terminate or reduce all or a portion of the revolving credit facility.

All obligations under the Credit Agreement are unconditionally guaranteed by the Company’s material U.S. subsidiaries and the obligations of the Company and such subsidiaries under the Credit Agreement and such guarantees are secured by, subject to certain exceptions, substantially all of their assets. The Credit Agreement also may, in certain circumstances, limit our ability to pay dividends or distributions. The Credit Agreement includes annual, quarterly and ad hoc financial reporting requirements and financial covenants requiring the Company to maintain maximum leverage ratios and a minimum fixed charge coverage ratio, as well as customary affirmative and negative covenants and events of default. Specifically, we may not exceed a maximum senior debt to EBITDA ratio, as defined, of 2.5:1 and a maximum total debt to EBITDA ratio, as defined, of 3.0:1. We must also maintain a fixed charge coverage ratio, as defined, of not less than 1.25:1. As of June 29, 2013, the Company was in compliance with its debt covenants.

UBS Secured Borrowing Facility

The Company also maintains a secured borrowing facility at UBS Financial Services, Inc., or UBS, using its marketable securities as collateral for the short-term line of credit. The line of credit bears an interest rate equal to LIBOR plus 0.85% (effective rate of 1.04% at June 29, 2013), and interest is adjusted and billed monthly. No principal payments are due on the borrowing; however, the line of credit is callable at any time. The amount available under the line of credit is based on a percentage of the market value of the underlying securities. If the equity value in the account falls below the minimum requirement, we must restore the equity value, or UBS may call the line of credit. As of June 29, 2013 and December 31, 2012, there were no amounts outstanding under the line of credit, and the maximum available borrowings were $5.0 million and $5.1 million, respectively.

Debt Repaid Upon Merger with LINC

On April 21, 2011, LINC executed a Revolving Credit and Term Loan Agreement with a syndicate of banks to refinance a substantial portion of outstanding secured debt and a portion of outstanding dividend payable to CenTra. The syndicated senior secured loan package included a $40 million revolving credit facility, a $25 million equipment credit facility, and a $30 million senior secured term loan. Comerica Bank acted as lead arranger for the agreement and was the administrative agent.

$40 million Revolving Credit Facility

Borrowings outstanding at any time under the revolving credit facility were limited to the value of eligible accounts receivable of LINC’s principal operating subsidiaries, pursuant to a monthly borrowing base certificate. At December 31, 2011, the $14.0 million revolver advance was secured by, among other assets, eligible accounts receivable totaling $35.7 million. At December 31, 2011, interest accrued at 2.04% based on 30-day LIBOR.

$25 million Equipment Credit Facility

The equipment credit facility was available to refinance existing indebtedness and to finance capital expenditures including in connection with acquisitions through advances available until April 21, 2014. At December 31, 2011, interest accrued at 2.04% based on 30-day LIBOR, and the outstanding balance under the equipment credit facility was $11.1 million.

$30 million Senior Secured Term Loan

Proceeds of the term loan were advanced on April 21, 2011 and used to fund initial distributions described in the Revolving Credit and Term Loan Agreement. At December 31, 2011, interest accrued at 3.29% based on 30-day LIBOR, and the outstanding balance under the term loan was $30.0 million.

Fifth Third Bank Equipment Financing Facility

At December 31, 2011, interest accrued at 1.65% based on 30-day LIBOR, and the principal outstanding was $3.0 million, which was collateralized by transportation equipment with a carrying amount of $3.8 million.

Dividend Distribution Promissory Note

At December 31, 2011, a net dividend payable to CenTra, LINC’s former parent and an affiliate of the Company, totaling $27.0 million was outstanding. Any unpaid amount was payable in cash on or before December 31, 2013. At December 31, 2011, interest accrued at a fixed rate of 1.64%.

Fair Value Measurements and Disclosures

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.

We segregate all financial assets 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, 2013
	Level 1		Level 2		Level 3		Fair Value Measurement
Assets
Cash equivalents	$	24	$	—	$	—	$	24
Marketable securities		10,249		—		—		10,249

Total Assets	$	10,273	$	—	$	—	$	10,273


	December 31, 2012
	Level 1		Level 2		Level 3		Fair Value Measurement
Assets
Cash equivalents	$	23	$	—	$	—	$	23
Marketable securities		9,962		—		—		9,962

Total Assets	$	9,985	$	—	$	—	$	9,985

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.

Our senior debt and line of credit consist of variable rate borrowings. The carrying value of these borrowings approximate fair value because the applicable interest rates are adjusted frequently based on short-term market rates.

Transactions with Affiliates

Through December 31, 2004, we were a wholly-owned subsidiary of CenTra, Inc. On December 31, 2004, CenTra distributed all of our common stock to the shareholders of CenTra. Subsequent to our initial public offering in 2005, our majority shareholders retained and continue to hold a controlling interest in us. CenTra and affiliates of CenTra provide administrative support services to us, including legal, human resources, and tax services. The cost of these services is based on the actual or estimated utilization of the specific service. Management believes these charges are reasonable. However, the costs of these services charged to us are not necessarily indicative of the costs that would have been incurred if we had internally performed or acquired these services as a separate unaffiliated entity.

In addition to the administrative support services described above, we purchase other services from affiliates. Following is a schedule of cost incurred for services provided by affiliates for the thirteen weeks and twenty-six weeks ended June 29, 2013 and June 30, 2012 (in thousands):


	Thirteen weeks ended				Twenty-six weeks ended
	June 29, 2013		June 30, 2012		June 29, 2013		June 30, 2012

Contracted transportation services		83		81		149		127

Total	$	11,658	$	12,466	$	25,201	$	25,901

In connection with our transportation services, we also routinely cross the Ambassador Bridge between Detroit, Michigan and Windsor Ontario, and we pay tolls and other fees to certain related entities which are under common control with CenTra. CenTra also charges us for the direct variable cost of various maintenance, fueling and other operational support costs for services delivered at their trucking terminals that are geographically remote from our own facilities. Such activities are billed when incurred, paid on a routine basis, and reflect actual labor utilization, repair parts costs or quantities of fuel purchased.

A significant number of our transportation and logistics service operations are located at facilities leased from affiliates. As of June 29, 2013, we occupy 35 such 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, 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 or coordinated by this affiliate.

Other services from affiliates, including leased real estate, insurance and employee benefit plans, and 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, 2013 and December 31, 2012, amounts due to affiliates were $5.7 million and $4.1 million, respectively.

Services provided by UTSI to Affiliates

We may assist our affiliates with selected transportation and logistics services in connection with their specific customer contracts or purchase orders.

At June 29, 2013 and December 31, 2012, amounts due from affiliates were $2.7 million and $3.6 million, respectively.

The Company also retained the law firm of Sullivan Hincks & Conway to provide legal services during the period. Daniel C. Sullivan, a member of our Board, is a partner at Sullivan Hincks & Conway. Amounts paid for legal services during the thirteen and twenty-six weeks ended June 29, 2013 were $3,000. Amounts paid for legal services during the thirteen and twenty-six weeks ended June 30, 2012 were $8,000 and $112,000, respectively.

On October 1, 2012, we completed the acquisition of LINC. Our principal shareholders beneficially owned, in the aggregate, 100% of the common stock of LINC. See Note 2 “Business Combinations - Acquisition Accounted for Between Entities Under Common Control.”

Stock Based Compensation

Stock Based Compensation

In December 2004, our Board of Directors adopted the 2004 Stock Incentive Plan, or the Plan, which became effective upon completion of the Company’s initial public offering. The Plan allows for the issuance of a total of 500,000 shares of common stock. The grants may be made in the form of restricted stock bonuses, restricted stock purchase rights, stock options, phantom stock units, restricted stock units, performance share bonuses, performance share units or stock appreciation rights.

On December 20, 2012, the Company granted 178,137 shares of restricted stock to certain of its employees. The restricted stock grants vested 20% on December 20, 2012, and an additional 20% will vest on each anniversary of the grant through December 20, 2016, subject to continued employment of the grantee with the Company.

The following table summarizes the status of the Company’s non-vested shares and related information for the period indicated:


	Shares		Weighted Average Grant Date Fair Value
Non-vested at January 1, 2013		142,511	$	16.42
Granted		—	$	—
Vested		—	$	—
Forfeited		—	$	—

Balance at June 29, 2013		142,511	$	16.42

As of June 29, 2013, there was $2.3 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. That cost is expected to be recognized over a weighted-average period of 4 years.

Earnings Per Share [Abstract]

Earnings Per Share

(10)

Earnings Per Share

Basic earnings per common share amounts are based on the weighted average number of common shares outstanding, excluding outstanding non-vested restricted stock, and diluted earnings per share amounts are based on the weighted average number of common shares outstanding, including outstanding non-vested restricted stock, plus incremental shares that would have been outstanding upon the assumed exercise of any dilutive stock options. For the thirteen weeks and twenty-six weeks ended June 29, 2013, there were 142,511 weighted average non-vested shares of restricted shares included in the denominator for the calculation of diluted earnings per share. For the thirteen weeks and twenty-six weeks ended June 30, 2012, the Company had no common stock equivalents; therefore, diluted earnings per share are equal to basic earnings per share.

Unaudited Pro Forma Earnings Per Share

Prior to its acquisition by Universal on October 1, 2012, LINC was an “S” Corporation for U.S. federal income tax purposes. As a result, LINC had no U.S. federal income tax liability, but had state and local liabilities in certain jurisdictions attributable to earnings as an “S” Corporation. Pro forma basic and diluted earnings per share have been computed to give effect to the termination of LINC’s “S” Corporation status and acquisition by Universal, which changes the provision for income taxes for each period presented. For the thirteen weeks and twenty-six ended June 30, 2012, we assume a blended statutory federal, state and local rate of 38.7% and 38.9%, respectively.

The following table sets forth a reconciliation of the numerator and denominator used in the calculation of basic and diluted earnings per share for each 2012 period presented (in thousands, except per share data):

Segment Reporting

Segment Reporting

As of March 30, 2013, certain integration activities in connection with our acquisition of LINC were not concluded. As such, we reported LINC’s financial performance separately from our single reportable segment that predated the acquisition. During the thirteen week period ended June 29, 2013, we determined that our financial results should be report 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.

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. This presentation reflects the manner in which management evaluates our operating segments, including an evaluation of economic characteristics and applicable aggregation criteria. There has been no impact on our consolidated balance sheets, statements of income, comprehensive income or cash flows for any period. Prior period segment information, including as reflected in the thirteen and twenty-six weeks ended June 30, 2012, has been adjusted to reflect the change in segment reporting.

The following tables summarize information about the Company’s reportable segments as of and for the thirteen week and twenty-six week period ended June 29, 2013 and June 30, 2012 (in thousands):
