our three core value drivers are : obtaining profitable new business . we attempt to obtain profitable new business by using our technical expertise and application skill and our detailed knowledge of our customer base and the individual niche markets in which we operate . we have regularly been successful in identifying and developing both aftermarket and oem products to drive our growth . improving our cost structure . we are committed to maintaining and continuously improving our lean cost structure through detailed attention to the cost of each of the products that we offer and our organizational structure , with a focus on reducing the cost of each . providing highly engineered value-added products to customers . we focus on the engineering , manufacturing and marketing of a broad range of highly engineered niche products that we believe provide value to our customers . we believe we have been consistently successful in communicating to our customers the value of our products . this has generally enabled us to price our products to fairly reflect the value we provide and the resources required to do so . selective acquisition strategy . we selectively pursue the acquisition of proprietary aerospace component businesses when we see an opportunity to create value through the application of our three core value-driven operating strategies . the aerospace industry , in particular , remains highly fragmented , with many of the companies in the industry being small private businesses or small non-core operations of larger businesses . we have significant experience among our management team in executing acquisitions and integrating acquired businesses into our company and culture . as of the date of this report , we have successfully acquired approximately 60 businesses and or product lines since our formation in 1993. many of these acquisitions have been integrated into an existing transdigm production facility , which enables a higher production capacity utilization , which in turn improves gross profit levels due to the ability to spread the fixed manufacturing overhead costs over higher production volume . 25 acquisitions during the previous three fiscal years are more fully described in note 2 , “ acquisitions , ” in the notes to the consolidated financial statements included herein . critical accounting policies our consolidated financial statements have been prepared in conformity with gaap , which often requires the judgment of management in the selection and application of certain accounting principles and methods . management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations . however , investors are cautioned that the sensitivity of financial statements to these methods , assumptions and estimates could create materially different results under different conditions or using different assumptions . below are those policies applied in preparing our financial statements that management believes are the most dependent on the application of estimates and assumptions . for additional accounting policies , see note 3 , “ summary of significant accounting policies , ” in the notes to the consolidated financial statements included herein . revenue recognition and related allowances : revenue is recognized from the sale of products when title and risk of loss passes to the customer , which is generally at the time of shipment . substantially all product sales are made pursuant to firm , fixed-price purchase orders received from customers . collectibility of amounts recorded as revenue is reasonably assured at the time of sale . provisions for returns , uncollectible accounts and the cost of repairs under contract warranty provisions are provided for in the same period as the related revenues are recorded and are principally based on historical results modified , as appropriate , by the most current information available . we have a history of making reasonably dependable estimates of such allowances ; however , due to uncertainties inherent in the estimation process , it is possible that actual results may vary from the estimates and the differences could be material . allowance for doubtful accounts : management estimates the allowance for doubtful accounts based on the aging of the accounts receivable and customer creditworthiness . the allowance also incorporates a provision for the estimated impact of disputes with customers . management 's estimate of the allowance amounts that are necessary includes amounts for specifically identified credit losses and estimated credit losses based on historical information . the determination of the amount of the allowance for doubtful accounts is subject to significant levels of judgment and estimation by management . depending on the resolution of potential credit and other collection issues , or if the financial condition of any of the company 's customers were to deteriorate and their ability to make required payments were to become impaired , increases in these allowances may be required . historically , changes in estimates in the allowance for doubtful accounts have not been significant . inventories : inventories are stated at the lower of cost or market . cost of inventories is generally determined by the average cost and the first-in , first-out ( fifo ) methods and includes material , labor and overhead related to the manufacturing process . because the company sells products that are installed on airframes that can be in-service for 25 or more years , it must keep a supply of such products on hand while the airframes are in use . where management estimated that the current market value was below cost or determined that future demand was lower than current inventory levels , based on historical experience , current and projected market demand , current and projected volume trends and other relevant current and projected factors associated with the current economic conditions , a reduction in inventory cost to estimated net realizable value was made by recording a provision included in cost of sales . story_separator_special_tag net income for the fiscal year ended september 30 , 2016 of $ 586.4 million was decreased by dividend equivalent payments of $ 3.0 million resulting in net income available to common shareholders of $ 583.4 million . the decrease in earnings per share of $ 2.51 per share to $ 7.88 per share is a result of the factors
