The Neeltran Acquisition completed by the Company during the fiscal year ended March 31, 2022 has been accounted for under the purchase method of accounting in accordance with ASC 805, Business Combinations. The Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of Neeltran Acquisition. The excess of the purchase price paid by the Company over the estimated fair value of net assets acquired has been recorded as goodwill. As Neeltran was previously a private company, the adoption of Accounting Standards Codification 842 ("ASC 842") was completed as part of the Neeltran Acquisition. See Note 15, "Leases" for further details. Neeltran had previously adopted Accounting Standards Codification 606, Revenue from Contracts with Customers ("ASC 606") as part of prior year audited financial statements. The following table summarizes the allocation of the purchase price based on the estimated fair value of the assets acquired and liabilities assumed in connection with the Neeltran Acquisition (in millions):
Cash and short-term investments |  | $ | 0.5 |
Net working capital (excluding inventory and deferred revenue) |  |  | (0.9 | )
Inventory |  |  | 9.0 |
Property, plant and equipment |  |  | 6.5 |
Deferred revenue |  |  | (10.0 | )
Deferred tax liability |  |  | (2.3 | )

Inventory include s a $0.6 million adjustment to step up the inventory balance to fair value consistent with the purchase price allocation. The fair value was based on the estimated selling price of the inventory, less the remaining manufacturing and selling cost and a normal profit margin on those manufacturing and selling efforts. The inventory step up adjustment increased cost of revenue by $0.6 million in the twelve month period ended March 31, 2022 as the inventory was sold. This increase is not reflected in the pro forma condensed combined statements of operations because it does not have a continuing impact beyond the first year. Backlog of $0.1 million was evaluated using the multi period excess earnings method under the income approach. The contracts with customers do not provide for any guarantees to source all future requirements from the Company. The amortization method being utilized is economic consumption estimated over a two year period with the expense being allocated to cost of revenues. ﻿ Customer relationships of $3.5 million relates to customers currently under contract and was determined based on a multi period excess earnings method under the income approach. The method of amortization being utilized is the economic consumption over 7 years with the expense being allocated to SG&A. Trade names and trademarks of $1.2 million were reviewed using the assumption that the Company would continue to utilize the Neeltran trade name indefinitely. The relief from royalty method was utilized using a 1% royalty rate on revenues with a 24.5% discount rate over 15 years. The goodwill represents the value associated with the acquired workforce and expected synergies related to the business combinations of the two companies. Goodwill resulting from the Neeltran Acquisition was assigned to the Company's Grid business segment. Goodwill recognized in the Neeltran Acquisition is not deductible for tax purposes. The Company has finalized its purchase price allocation for the Neeltran Acquisition, and there were no changes to the net assets and goodwill recorded by the Company as of May 6, 2021.

Additionally, the Company may issue to the selling stockholders up to an additional 1,000,000 shares of common stock upon NEPSI’s achievement of specified revenue objectives during varying periods of up to four years following closing of the NEPSI Acquisition. This contingent consideration is recorded as a derivative liability based on a Monte Carlo simulation to determine fair value at the time of issuance. NEPSI is now a wholly-owned subsidiary of the Company and is operated and reported as a component of its Grid business unit. The NEPSI Acquisition completed by the Company during the fiscal year ended March 31, 2021 has been accounted for under the purchase method of accounting in accordance with ASC 805, Business Combinations. The Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of NEPSI Acquisition. The excess of the purchase price paid by the Company over the estimated fair value of net assets acquired has been recorded as goodwill. As NEPSI was previously a private company, the adoption of ASC 606 was completed as part of the NEPSI Acquisition. See Note 3, "Revenue Recognition" for further details. There were no leases acquired and the NEPSI Acquisition had no impact to the Company's reporting under ASC 842. The total purchase price of approximately $42.4 million includes the fair value of shares of the Company’s common stock issued at closing, cash paid, and contingent consideration as follows (in millions):

NEPSI Acquisition costs of $0.3 million were recorded in selling, general and administrative ("SG&A") costs for the fiscal year ended March 31, 2021. The fair value of the contingent consideration was determined using a Monte Carlo model and is accounted for as a derivative liability which is revalued at the fair value determined at each subsequent balance sheet date until the contingencies are resolved and the shares to be issued are determined, with the change in fair value recorded in the current period operating loss or (income). See Note 13, "Contingent Consideration" for further details and a summary of key assumptions used to determine fair value in each period.

Net working capital (excluding inventory and deferred revenue) |  | $ | 0.1 |
Inventory |  |  | 4.2 |
Property, plant and equipment |  |  | 2.3 |

Total purchase consideration |  | $ | 42.4 |
Inventory includes a $1.0 million adjustment to step up the inventory balance to fair value consistent with the purchase price allocation. The fair value was determined based on the estimated selling price of the inventory, less the remaining manufacturing and selling cost and a normal profit margin on those manufacturing and selling efforts. The $1.0 million step up adjustment increased cost of revenue in the fiscal year ended March 31, 2021 as the inventory was sold. This increase is not reflected in the pro forma condensed combined statements of operations because it does not have a continuing impact beyond the first year. Backlog of $0.6 million was evaluated using the multi period excess earnings method under the income approach. The contracts with customers do not provide for any guarantees to source all future requirements from the Company. The amortization method being utilized is economic consumption estimated over a two year period with the expense being allocated to cost of revenues. Customer relationships of $6.1 million relates to customers currently under contract and was determined based on a multi period excess earnings method under the income approach. The method of amortization being utilized is the economic consumption over 7 years with the expense being allocated to SG&A. Trade names and trademarks of $0.6 million were reviewed, using the assumption that the Company would continue to utilize the NEPSI trade name indefinitely. The relief from royalty method was utilized using an 8% royalty rate on revenues with a 13% discount rate over 8 years. Goodwill represents the value associated with the acquired workforce and expected synergies related to the business combination of the two companies. Goodwill resulting from the NEPSI Acquisition was assigned to the Company’s Grid business segment. Goodwill recognized in the NEPSI Acquisition is not deductible for tax purposes. The $1.7 million of deferred tax liability is primarily related to inventory step up and intangibles.
