[1] The determination of fair value related to the inventory acquired was still in progress as of the date of this filing. The amount above represents only the carrying value of the inventory on TRP’s balance sheet as of the acquisition date. The measurement period adjustment noted above for inventory relates to additional inventory received from TE, as well as inventory on customer consignments that was not previously accounted for.

[2] The appraisals related to machinery and equipment acquired were incomplete as of this filing date and, as such, the amount noted above represents only the carrying value of those assets on TRP’s balance sheet as of the acquisition date. The measurement period adjustment noted above for property, plant and equipment relates to equipment that could not be located upon a physical inventory of the assets acquired.

[3] The Company has identified certain intangible assets related to the TRP acquisition, including technology, license agreements and customer lists, which are being valued by a third-party appraiser. These appraisals were not complete as of the date of this filing.

[4] The amount of goodwill is provisional as of the filing date, as the fair value determination of inventory acquired, and appraisals related to property, plant and equipment and various intangible assets are still underway. As the final amount of goodwill has not yet been determined or allocated by segment, the Company is unable to determine at this time the portion of goodwill, if any, that will be deductible for tax purposes.

[5] Deferred consideration represents the Company’s estimate of a working capital adjustment which is payable to the seller. Such adjustment must be agreed upon between the Company and the seller, and has not yet been finalized as of the date of this filing.

[6] Deferred consideration represents the Company's estimate of a working capital adjustment which is payable to the seller. Such adjustment must be agreed upon between the Company and the seller, and has not yet been finalized as of the date of this filing.
