The Company continually evaluates potential acquisitions that either strategically fit within the Company’s existing portfolio or expand the Company’s portfolio into new product lines or adjacent markets. The Company has completed a number of acquisitions that have been accounted for as business combinations and have resulted in the recognition of goodwill in the Company’s financial statements. This goodwill includes the know-how of the assembled workforce, the ability of the workforce to further improve technology and product offerings, customer relationships and the expected cash flows resulting from these efforts. Goodwill may also include expected synergies resulting from the complementary strategic fit these businesses bring to existing operations. The business acquisition discussed below is included in the Company’s results of operations from their respective dates of acquisition.

On April 1, 2019, the Company entered into a Stock Purchase Agreement, or the Purchase Agreement, with Mission Mode Solutions, Inc., or Mission Mode, pursuant to which the Company purchased all of the issued and outstanding shares of stock of Mission Mode for base consideration of $6.8 million. There is also a contingent payment of up to $1.0 million that can be earned in addition to the base consideration by the sellers based on successfully converting Mission Mode’s customers to the Company’s products. At the date of the acquisition, the Company preliminarily assessed the probabilities of Mission Mode meeting the future sales and billing thresholds and determined them to be probable. Therefore, contingent consideration was recorded as part of the purchase price allocation and the preliminary fair value of the contingent consideration was determined to be $0.6 million. The Company’s acquisition of Mission Mode was made primarily to expand the Company’s customer base and to a lesser extent to complement some of the existing facets of its business with the Company’s existing customers.

The Company accounted for the acquisition of Mission Mode using the acquisition method of accounting for business combinations under ASC 805, Business Combinations. The total purchase price is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date.

As the Company finalizes their estimation of the fair value of the assets acquired and liabilities assumed, additional adjustments may be recorded during the measurement period (a period not to exceed 12 months). Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives and the expected future cash flows and related discount rates, can materially impact the Company’s results of operations. Significant inputs used for the model

included the amount of cash flows, the expected period of the cash flows and the discount rates. The finalization of the acquisition accounting valuation assessment may result in a change in the valuation of the deferred tax assets and liabilities, deferred revenue, contingent consideration and intangible assets, which could have a material impact on the Company’s results of operations and financial position.

The following table summarizes the allocation of the purchase consideration and the estimated fair value of the assets acquired and the liabilities assumed for the acquisition of Mission Mode made by the Company. The purchase price allocations for Mission Mode included in the table below are preliminary. The following table summarizes the aggregate consideration for Mission Mode during the three months ended June 30, 2019 (in thousands):

	Mission Mode
Assets acquired
Accounts receivable		295
Other assets		7
Property and equipment		6
Trade names		220
Acquired technology		310
Customer relationships		4,600
Goodwill		2,918
Total assets acquired	$	8,356
Liabilities assumed
Accounts payable and accrued expenses		152
Deferred revenue		880
Other liabilities		10
Net assets acquired	$	7,314
Consideration paid
Cash paid, net of cash acquired		6,764
Contingent consideration		550
Total	$	7,314

The weighted average useful life of all identified acquired intangible assets is 6.90 years. The weighted average useful lives for acquired technologies, customer relationships and trade names are 3.0 years, 7.0 years and 1.0 years, respectively. Identifiable intangible assets with definite lives are amortized over the period of estimated benefit using the straight-line method and the estimated useful lives of one to seven years. The straight-line method of amortization represents the Company’s best estimate of the distribution of the economic value of the identifiable intangible assets.

As a result of the acquisition, the Company recorded $2.9 million of goodwill. The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to the integration of Mission Mode’s products with the Company's other solutions. The Company believes that the factors listed above in relation to the purchase of Mission Mode support the amount of goodwill recorded as a result of the purchase price paid for the acquisition, in relation to other acquired tangible and intangible assets. The resulting goodwill from the Mission Mode acquisition is not deductible for income tax purposes.

For the three and six months ended June 30, 2019, the Company incurred transaction costs of $0.1 million and $0.1 million, respectively, in connection with the Mission Mode acquisition, which were expensed as incurred and included in general and administrative expenses within the accompanying consolidated statements of operations.

Neither the investment in the assets nor the results of operations of the acquisition of Mission Mode was significant to the Company’s consolidated financial position or results of operations, and thus pro forma information is not presented.
