Fair Value Disclosures [Abstract] |
Fair Value of Financial Disclosures | Fair Value of Financial Instruments The Company's financial instruments include cash and cash equivalents, cash value of life insurance, accounts receivable, derivative instruments, accounts payable, earn-out liabilities and debt instruments. For short-term instruments, other than those required to be reported at fair value on a recurring basis and for which additional disclosures are included below, management concluded the historical carrying value is a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization. Therefore, as of December 31, 2016 and December 31, 2015, the carrying amount for cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Company's line of credit, which are based on variable interest rates, approximates their fair value. The carrying amount for cash value of life insurance and long-term debt at December 31, 2015 approximated their fair values. The Company has two Level 2 financial assets and liabilities. The fair value of the interest rate swap contract entered into on August 21, 2012 was an asset of $31,000 and a liability of $40,000 at December 31, 2016 and December 31, 2015, respectively. During the third quarter of 2016, the swap contract entered into on September 3, 2013 was settled and as result had no value at December 31, 2016. The fair value of this interest rate swap contract was a liability of $206,000 at December 31, 2015. The interest rate swaps were priced using discounted cash flow techniques which are corroborated by using non-binding market prices. Changes in the swaps' fair value were recorded in current assets or liabilities, as appropriate, with corresponding offsetting entries to other income (expense). Significant inputs to the discounted cash flow model include projected future cash flows based on projected one-month LIBOR and the average margin for companies with similar credit ratings and similar maturities. These are classified as Level 2 as they are not actively traded and are valued using pricing models that use observable market inputs. See Note 17 for further discussion of interest rate swaps. The earn-out liability payments resulting from the acquisitions of Palmer and Specialty are classified as Level 3. The amount of the total earn-out liability to the prior owners of Palmer was determined using management's best estimate of Palmer's EBITDA for the three-year earn-out period which would determine the amount of the ultimate payment to be made. The amount of the total earn-out liability due to the prior owner of Specialty was determined using management's best estimate of Specialty's revenues for the two-year earn-out period which determined the amount of the ultimate payment to be made. Factors such as volume increases, selling price increases and inflation were used to develop a base projection. The Company believed additional costs would be required at Palmer to improve employee turnover, safety, internal controls, etc. These estimated costs were deducted in order to determine projected Palmer's EBITDA. The Company's cost of borrowing at that time was used to determine the present value of these expected payments. Each quarter-end, the Company re-evaluated its assumptions and adjustments to the estimated present value of the expected payments to be made, if required. During the three months ended June 28, 2014, the Company reviewed the Palmer earn-out reserve for the second and third year payments and determined the EBITDA threshold target of $5,825,000 for the period from August 22, 2013 to August 21, 2014 ("Year 2") would not be attained, and therefore, the earn-out payment of $2,500,000 for Year 2 was not made to the former Palmer shareholders. Also, the Company did not expect Palmer to meet the EBITDA threshold target of $6,825,000 during the final twelve month earn-out period, which was used in the earn-out calculation for year three. However, it was expected to reach the minimum $5,825,000 threshold and the earn-out reserve was adjusted accordingly. As a result, the Company adjusted the earn-out liability to the present value of the Company's current estimates by recognizing a gain of approximately $3,476,000 during the second quarter of 2014. During the three months ended April 4, 2015, the Company reviewed the Palmer earn-out reserve for the third year payment and determined the EBITDA minimum threshold of $5,825,000 would not be attained. As a result, the remaining earn-out liability to the former shareholders of Palmer was reduced to zero and a gain of approximately $2,483,000 was recognized during the first quarter of 2015. The earn-out period expired August 21, 2015 and no earn-out payments were made for the third year. During the second quarter 2015, the Company adjusted the preliminary estimate of the earn-out liability to the former owner of Specialty by approximately $2,419,000. Based on the heavy dependence on the energy sector by Specialty's Houston location and as a result of continued evaluation by the Company, the preliminary estimate was revised and goodwill was adjusted accordingly for the final estimate. During the third quarter 2015, the Company completed its revenue projections during its 2016 planning processes. As a result, the Company determined the fair value of the earn-out liability was zero and reduced the remaining earn-out liability by recognizing a gain of approximately $2,414,000 during the third quarter 2015 and remained at zero for the period December 31, 2015. There were no changes in the estimated fair value of Specialty's earn-out liability during 2016. The earn-out period expired on November 22, 2016 with no earn-out payment made to the previous owners of Specialty. The following table presents a summary of changes in fair value of the Company's Level 3 liabilities measured on a recurring basis for 2015:
|  | Level 3 Inputs
Balance at January 3, 2015 |  | $ | 7,256,387 |
Interest expense charged during the year |  | 60,096 |
Reduction due to the finalization of Specialty's beginning balance sheet |  | (2,419,035 | )
Change in the fair value of Specialty's earn-out liability |  | (2,414,115 | )
Change in the fair value of Palmer's earn-out liability |  | (2,483,333 | )
Balance at December 31, 2015 |  | $ | — |
There were no transfers of assets or liabilities between Level 1, Level 2 and Level 3 in the years ended December 31, 2016 or December 31, 2015. There have also been no changes in the fair value methodologies used by the Company during the years ended December 31, 2016 or December 31, 2015.
