effective tax rate for fiscal 2013 was lower by approximately 3% due to $6.6 million recorded as a result of the reversal of certain prior period tax liabilities and a tax benefit of $6.3 million from the reinstatement of the U. S.  federal research and development tax credit in January 2013 retroactive to January 1, 2012.
Net Income
## Table 0 ##
The increase in net income in fiscal 2015 as compared to fiscal 2014 was primarily a result of the $78.4 million increase in operating income partially offset by the $13.2 million increase in provision for income taxes.
The decrease in net income in fiscal 2014 as compared to fiscal 2013 was primarily a result of the $85.4 million decrease in nonoperating income partially offset by the $41.8 million decrease in provision for income taxes.
The impact of inflation and foreign currency exchange rate movement on our results of operations during the past three fiscal years has not been significant.
Divestitures On October 31, 2013, we completed the sale of the assets and intellectual property related to our microphone product line to InvenSense, Inc.  (InvenSense).
We received $100.0 million in cash for the assets and intellectual property and after providing for the write-off of inventory, fixed assets and other costs incurred to complete the transaction, recorded a net gain of $85.4 million in nonoperating income during fiscal 2013.
The sale of the assets and intellectual property related to the microphone product line did not qualify as a discontinued operation as it was not considered to be a component of the Company per the applicable guidance.
Acquisitions On July 22, 2014, we completed our acquisition of Hittite (the Acquisition), a company that designed and developed high performance integrated circuits, modules, subsystems and instrumentation for radio frequency, microwave and millimeterwave applications.
The total consideration paid to acquire Hittite was approximately $2.4 billion, financed through a combination of existing cash on hand and a 90-day term loan facility of $2.0 billion.
We recognized assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition, resulting in the recognition of $1.4 billion of goodwill and $666.4 million of intangible assets, including $0.9 million of in-process research and development intangible assets.
We recognized approximately $50.9 million of transaction-related costs, including legal, accounting, severance, debt financing, interest and other related fees of which approximately $9.7 million were expensed in fiscal 2015 and $41.2 million in fiscal 2014.
These costs are included in the consolidated statements of income in operating expenses within SMG&A expenses as well as nonoperating expenses.
The Acquisition resulted in the creation of a new operating segment.
We continue to operate and track our results in one reportable segment based on the aggregation of six operating segments.
The following unaudited pro forma consolidated financial information presents our combined results of operations after giving effect to the Acquisition and assumes that the Acquisition, which closed on July 22, 2014, was completed on November 4, 2012 (the first day of the Company’s 2013 fiscal year).
The pro forma consolidated financial information has been calculated after applying our accounting policies and includes adjustments for amortization expense of acquired intangible assets, transaction-related costs, increase in cost of sales for inventory acquired and depreciation of property, plant and equipment, and interest expense for the debt incurred to fund the Acquisition, together with the consequential tax effects.
These pro forma results have been prepared for comparative purposes only and do not purport to be indicative of our operating results that would have been achieved had the Acquisition actually taken place on November 4, 2012.
In addition, these results are not intended to be a projection of future results and do not reflect events that may occur after the Acquisition, including but not limited to revenue enhancements, cost savings or operating synergies that the combined Company may achieve as a result of the Acquisition.
We, in the normal course of business operations, have issued product warranties related to equipment sales.
Also, contracts often contain standard terms and conditions which typically include a warranty and indemnification to the buyer that the goods and services purchased do not infringe on third-party intellectual property rights.
The provision for estimated future costs relating to warranties is not material to the consolidated financial statements.
We do not expect that any sum we may have to pay in connection with guarantees and warranties will have a material adverse effect on our consolidated financial condition, liquidity, or results of operations.
UNCONDITIONAL PURCHASE OBLIGATIONS We are obligated to make future payments under unconditional purchase obligations as summarized below:
## Table 1 ##
Approximately $4,000 of our unconditional purchase obligations relate to helium purchases, which include crude feedstock supply to multiple helium refining plants in North America as well as refined helium purchases from sources around the world.
As a rare byproduct of natural gas production in the energy sector, these helium sourcing agreements are medium- to long-term and contain take-or-pay provisions.
The refined helium is distributed globally and sold as a merchant gas, primarily under medium-term requirements contracts.
While contract terms in the energy sector are longer than those in merchant, helium is a rare gas used in applications with few or no substitutions because of its unique physical and chemical properties.
Approximately $330 of our long-term unconditional purchase obligations relate to feedstock supply for numerous HyCO (hydrogen, carbon monoxide, and syngas) facilities.
The price of feedstock supply is principally related to the price of natural gas.
However, long-term take-or-pay sales contracts to HyCO customers are generally matched to the term of the feedstock supply obligations and provide recovery of price increases in the feedstock supply.
Due to the matching of most long-term feedstock supply obligations to customer sales contracts, we do not believe these purchase obligations would have a material effect on our financial condition or results of operations.
The unconditional purchase obligations also include other product supply and purchase commitments and electric power and natural gas supply purchase obligations, which are primarily pass-through contracts with our customers.
Purchase commitments to spend approximately $350 for additional plant and equipment are included in the unconditional purchase obligations in 2017.
In addition, we have purchase commitments totaling approximately $500 in 2017 and 2018 relating to our long-term sale of equipment project for Saudi Aramco’s Jazan oil refinery.18.
CAPITAL STOCK Common Stock Authorized common stock consists of 300 million shares with a par value of $1 per share.
As of 30 September 2016, 249 million shares were issued, with 217 million outstanding.
On 15 September 2011, the Board of Directors authorized the repurchase of up to $1,000 of our outstanding common stock.
We repurchase shares pursuant to Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended, through repurchase agreements established with several brokers.
We did not purchase any of our outstanding shares during fiscal year 2016.
At 30 September 2016, $485.3 in share repurchase authorization remains.
DISH NETWORK CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - Continued F-40 14.
Stock-Based Compensation We account for our stock-based compensation in accordance with Statement of Financial Accounting Standards No.123R (As Amended), “Share-Based Payment” (“SFAS 123R”), which (i) revises Statement of Financial Accounting Standards No.123, “Accounting and Disclosure of Stock-Based Compensation,” (“SFAS 123”) to eliminate both the disclosure only provisions of that statement and the alternative to follow the intrinsic value method of accounting under Accounting Principles Board Opinion No.25, “Accounting for Stock Issued to Employees” (“APB 25”) and related interpretations, and (ii) requires the cost resulting from all share-based payment transactions with employees be recognized in the results of operations over the period during which an employee provides the requisite service in exchange for the award and establishes fair value as the measurement basis of the cost of such transactions.
Stock Incentive Plans In connection with the Spin-off, as provided in our existing stock incentive plans and consistent with the Spin-off exchange ratio, each DISH Network stock option was converted into two stock options as follows:  an adjusted DISH Network stock option for the same number of shares that were exercisable under the original DISH Network stock option, with an exercise price equal to the exercise price of the original DISH Network stock option multiplied by 0.831219.
 a new EchoStar stock option for one-fifth of the number of shares that were exercisable under the original DISH Network stock option, with an exercise price equal to the exercise price of the original DISH Network stock option multiplied by 0.843907.
Similarly, each holder of DISH Network restricted stock units retained his or her DISH Network restricted stock units and received one EchoStar restricted stock unit for every five DISH Network restricted stock units that they held.
Consequently, the fair value of the DISH Network stock award and the new EchoStar stock award immediately following the Spin-off was equivalent to the fair value of such stock award immediately prior to the Spin-off.
We maintain stock incentive plans to attract and retain officers, directors and key employees.
Awards under these plans include both performance and non-performance based equity incentives.
As of December 31, 2008, we had outstanding under these plans stock options to acquire 21.8 million shares of our Class A common stock and 1.5 million restricted stock awards.
Stock options granted through December 31, 2008 were granted with exercise prices equal to or greater than the market value of our Class A common stock at the date of grant and with a maximum term of ten years.
While historically we have issued stock options subject to vesting, typically at the rate of 20% per year, some stock options have been granted with immediate vesting and other stock options vest only upon the achievement of certain company-wide objectives.
As of December 31, 2008, we had 57.5 million shares of our Class A common stock available for future grant under our stock incentive plans.
As of December 31, 2008, the following stock incentive awards were outstanding:
