note 2 2013 earnings per share the weighted average number of shares outstanding used to compute earnings per common share were as follows ( in millions ) : .

Table:
 | 2018 | 2017 | 2016
weighted average common shares outstanding for basic computations | 284.5 | 287.8 | 299.3
weighted average dilutive effect of equity awards | 2.3 | 2.8 | 3.8
weighted average common shares outstanding for diluted computations | 286.8 | 290.6 | 303.1
we compute basic and diluted earnings per common share by dividing net earnings by the respective weighted average number of common shares outstanding for the periods presented .
our calculation of diluted earnings per common share also includes the dilutive effects for the assumed vesting of outstanding restricted stock units ( rsus ) , performance stock units ( psus ) and exercise of outstanding stock options based on the treasury stock method .
there were no significant anti-dilutive equity awards for the years ended december 31 , 2018 , 2017 and 2016 .
note 3 2013 acquisition and divestitures consolidation of awe management limited on august 24 , 2016 , we increased our ownership interest in the awe joint venture , which operates the united kingdom 2019s nuclear deterrent program , from 33% ( 33 % ) to 51% ( 51 % ) .
consequently , we began consolidating awe and our operating results include 100% ( 100 % ) of awe 2019s sales and 51% ( 51 % ) of its operating profit .
prior to increasing our ownership interest , we accounted for our investment in awe using the equity method of accounting .
under the equity method , we recognized only 33% ( 33 % ) of awe 2019s earnings or losses and no sales .
accordingly , prior to august 24 , 2016 , the date we obtained control , we recorded 33% ( 33 % ) of awe 2019s net earnings in our operating results and subsequent to august 24 , 2016 , we recognized 100% ( 100 % ) of awe 2019s sales and 51% ( 51 % ) of its operating profit .
we accounted for this transaction as a 201cstep acquisition 201d ( as defined by u.s .
gaap ) , which requires us to consolidate and record the assets and liabilities of awe at fair value .
accordingly , we recorded intangible assets of $ 243 million related to customer relationships , $ 32 million of net liabilities , and noncontrolling interests of $ 107 million .
the intangible assets are being amortized over a period of eight years in accordance with the underlying pattern of economic benefit reflected by the future net cash flows .
in 2016 , we recognized a non-cash net gain of $ 104 million associated with obtaining a controlling interest in awe , which consisted of a $ 127 million pretax gain recognized in the operating results of our space business segment and $ 23 million of tax-related items at our corporate office .
the gain represented the fair value of our 51% ( 51 % ) interest in awe , less the carrying value of our previously held investment in awe and deferred taxes .
the gain was recorded in other income , net on our consolidated statements of earnings .
the fair value of awe ( including the intangible assets ) , our controlling interest , and the noncontrolling interests were determined using the income approach .
divestiture of the information systems & global solutions business on august 16 , 2016 , we divested our former is&gs business , which merged with leidos , in a reverse morris trust transaction ( the 201ctransaction 201d ) .
the transaction was completed in a multi-step process pursuant to which we initially contributed the is&gs business to abacus innovations corporation ( abacus ) , a wholly owned subsidiary of lockheed martin created to facilitate the transaction , and the common stock of abacus was distributed to participating lockheed martin stockholders through an exchange offer .
under the terms of the exchange offer , lockheed martin stockholders had the option to exchange shares of lockheed martin common stock for shares of abacus common stock .
at the conclusion of the exchange offer , all shares of abacus common stock were exchanged for 9369694 shares of lockheed martin common stock held by lockheed martin stockholders that elected to participate in the exchange .
the shares of lockheed martin common stock that were exchanged and accepted were retired , reducing the number of shares of our common stock outstanding by approximately 3% ( 3 % ) .
following the exchange offer , abacus merged with a subsidiary of leidos , with abacus continuing as the surviving corporation and a wholly-owned subsidiary of leidos .
as part of the merger , each share of abacus common stock was automatically converted into one share of leidos common stock .
we did not receive any shares of leidos common stock as part of the transaction and do not hold any shares of leidos or abacus common stock following the transaction .
based on an opinion of outside tax counsel , subject to customary qualifications and based on factual representations , the exchange offer and merger will qualify as tax-free transactions to lockheed martin and its stockholders , except to the extent that cash was paid to lockheed martin stockholders in lieu of fractional shares .
in connection with the transaction , abacus borrowed an aggregate principal amount of approximately $ 1.84 billion under term loan facilities with third party financial institutions , the proceeds of which were used to make a one-time special cash payment of $ 1.80 billion to lockheed martin and to pay associated borrowing fees and expenses .
the entire special cash payment was used to repay debt , pay dividends and repurchase stock during the third and fourth quarters of 2016 .
the obligations under the abacus term loan facilities were guaranteed by leidos as part of the transaction. .
