Xinye Acquisition

On June 8, 2013, Chart Asia Investment Company Limited (“Chart Asia”), a wholly-owned subsidiary of the Company, acquired 80% of the shares of Nanjing Xinye Electric Engineering Co., Ltd. (“Xinye”) for an aggregate cash purchase price of 18.7 million Chinese yuan (equivalent to $3,032), net of cash acquired. The remaining 20% will be retained by an original shareholder. Xinye will be operated as part of the Company's Distribution & Storage business segment. The Company is in the process of finalizing certain analyses; thus, the provisional measurements of the net assets acquired and goodwill are subject to change.

Xinye, located in Nanjing, Jiangsu Province, China, designs, manufactures and sells control systems and dispensers for the liquefied natural gas, compressed natural gas, and industrial gas industries. It also engages in the design and production of integrated circuit card systems and remote monitoring systems for natural gas mobile equipment. Xinye provides the Company localized dispensing and control technology and increases its penetration into the high growth natural gas markets in the Asian region.

AirSep Acquisition

On August 30, 2012, the Company acquired 100% of the equity interests of AirSep Corporation (“AirSep”) for an aggregate cash purchase price of $182,450 (including approximately $2,800 in acquisition-related tax benefits acquired and $10,000 of debt which was retired upon completion of the acquisition). AirSep, located in Amherst, New York, designs, manufactures, sells and services stationary, transportable, and portable oxygen concentrators and self-contained generators, standard generators, and packaged systems for industrial and medical oxygen generating systems. AirSep's results are included in the Company’s BioMedical segment.

The fair value of the net assets acquired and goodwill at the date of acquisition were $72,687 and $109,763, respectively. The allocation of the purchase price is based on the fair value of assets acquired and liabilities assumed, and the related income tax impact of the acquisition adjustments. The acquisition was made and goodwill was established due to the benefits that will be derived from the expansion of the oxygen concentrator business in the U.S., Europe and Asia, and the growth potential for the Company's commercial oxygen generation systems business.

The following table summarizes the fair values of the assets acquired and liabilities assumed in the AirSep acquisition on August 30, 2012.

AirSep provides warranties on certain of its products, generally for periods of five years or less. The warranty reserve is calculated considering historical warranty experience (general portion of the reserve) and specifically identified warranty issues (specific portion of the reserve). To calculate the general reserve, actual warranty claims are used to calculate an average experience rate to be applied against sales. This experience rate is used to record an estimated accrual at the time of the sale. The accrual is reviewed and adjusted periodically to reflect current information including costs to repair or replace the units. The Company reviews other factors to determine if there are any specific factors which could change the reserve. AirSep has experienced a significant number of warranty claims in one of its product lines. To calculate the specific reserve associated with this product line, the Company isolated the specific units which were being returned at significantly higher rates than normal. The entire population of these units was excluded from the general reserve and is considered in a specific reserve. The specific reserve considers the identified population, less units already returned, to estimate potential units that will be returned. Management then estimated the expected number of additional product returns based on historical returns experience for this product line. These expected future returns were multiplied by the estimated cost to replace the unit to establish a specific warranty reserve.

AirSep's identifiable intangible assets mainly include customer relationships and technology and are also comprised of product names, trademarks and trade names.

For the three months ended June 30, 2013, AirSep added $29,855 to sales. For the same period, the acquisition of AirSep increased operating income by $1,872 which included $2,638 in cost of goods sold to amortize the remaining portion of the write-up of inventory to fair value, $1,714 of intangible asset amortization expense and $1,267 in management retention expenses and severance costs.

For the six months ended June 30, 2013, AirSep added $56,869 to sales. For the same period, the acquisition of AirSep increased operating income by $3,175 which included $2,638 in cost of goods sold to amortize the remaining portion of the write-up of inventory to fair value, $3,428 of intangible asset amortization expense and $2,204 in management retention expenses and severance costs.

Pro-forma information related to the above acquisitions have not been presented because the impact on the Company’s consolidated results of operations is not material.

Contingent Consideration

The estimated fair value of total contingent consideration relating to acquisitions in prior years was valued using a discounted cash flow approach, which includes assumptions for the probabilities of achieving gross sales or gross profit targets and the discount rate applied to the projected payments. The valuation is performed using Level 3 inputs as defined in Note C. Changes in fair value of contingent consideration are recorded as selling, general and administrative expenses in the condensed consolidated statements of income and comprehensive income.

Potential payments may be paid over the next three years commencing April 1, 2013 until March 31, 2016 based on the attainment of certain revenue targets. Based on achieving certain revenue targets, the remaining maximum potential payout related to total contingent consideration is $3,000.

Increase in contingent consideration liabilities	135
Balance at June 30, 2013	$	2,125

For the three and six months ended June 30, 2013, total contingent consideration related to the BioMedical segment increased by $77 and $135, respectively.

For the six months ended June 30, 2012, total contingent consideration decreased by $3,865, which included a net decrease of $4,309 related to prior BioMedical segment acquisitions offset by an increase of $444 related to a prior Distribution & Storage segment acquisition.
