Description of Business
Westell Technologies, Inc. (the Company) is a holding company. Its wholly owned subsidiary, Westell, Inc., designs and distributes telecommunications products, which are sold primarily to major telephone companies. During the second quarter ended September 30, 2017, the Company dissolved Noran Tel, Inc. (NoranTel) a wholly owned subsidiary of Westell, Inc. NoranTel's operations have been fully incorporated into Westell, Inc. As a result of the wind-up of NoranTel, the Company recognized a one-time $0.6 million  foreign currency translation gain, which is presented in Other income, net on the Consolidated Statements of Operations.
Principles of Consolidation
The accompanying Consolidated Financial Statements include the accounts of the Company and its majority owned subsidiaries. The Consolidated Financial Statements have been prepared using accounting principles generally accepted in the United States (GAAP). All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and that affect revenue and expenses during the periods reported. Estimates are used when accounting for the allowance for uncollectible accounts receivable, net realizable value of inventory, product warranty accrued, relative selling prices, stock-based compensation, goodwill and intangible assets fair value, depreciation, income taxes, and contingencies, among other things. The Company bases its estimate on historical experience and on other assumptions that its management believes are reasonable under the circumstances. Actual results could differ from those estimates.
Reverse Stock Split
All common stock, equity, share and per share amounts in the financial statements and notes have been retroactively adjusted to reflect a one-for-four reverse stock split, which was effective June 7, 2017.
