STOCKHOLDERS’ EQUITY

Retained Earnings

The changes in retained earnings for the six months ended June 1, 2018 were as follows (in thousands):



Balance as of December 1, 2017	$	9,573,870

We account for treasury stock under the cost method. When treasury stock is re-issued at a price higher than its cost, the difference is recorded as a component of additional paid-in-capital in our condensed consolidated balance sheets. When treasury stock is re-issued at a price lower than its cost, the difference is recorded as a component of additional paid-in-capital to the extent that there are treasury stock gains to offset the losses. If there are no treasury stock gains in additional paid-in-capital, the losses upon re-issuance of treasury stock are recorded as a reduction of retained earnings in our condensed consolidated balance sheets.

Stock Repurchase Program

To facilitate our stock repurchase program, designed to return value to our stockholders and minimize dilution from stock issuances, we may repurchase shares in the open market or enter into structured repurchase agreements with third parties. In January 2017, our Board of Directors approved our current stock repurchase program granting us authority to repurchase up to $2.5 billion in common stock through the end of fiscal 2019. In May 2018, our Board of Directors granted us another authority to repurchase up to $8 billion in common stock through the end of fiscal 2021.

During the six months ended June 1, 2018 and June 2, 2017, we entered into several structured stock repurchase agreements with large financial institutions, whereupon we provided them with prepayments totaling $1 billion and $500 million, respectively. We enter into these agreements in order to take advantage of repurchasing shares at a guaranteed discount to the Volume Weighted Average Price (“VWAP”) of our common stock over a specified period of time. We only enter into such transactions when the discount that we receive is higher than the foregone return on our cash prepayments to the financial institutions. There were no explicit commissions or fees on these structured repurchases. Under the terms of the agreements, there is no requirement for the financial institutions to return any portion of the prepayment to us.

The financial institutions agree to deliver shares to us at monthly intervals during the contract term. The parameters used to calculate the number of shares deliverable are: the total notional amount of the contract, the number of trading days in the contract, the number of trading days in the interval and the average VWAP of our stock during the interval less the agreed upon discount. During the six months ended June 1, 2018, we repurchased approximately 4.3 million shares at an average price of $208.69 through structured repurchase agreements entered into during fiscal 2017 and the six months ended June 1, 2018. During the six months ended June 2, 2017 we repurchased approximately 4.3 million shares at an average price of $118.00 through structured repurchase agreements entered into during fiscal 2016 and the six months ended June 2, 2017.

For the six months ended June 1, 2018, the prepayments were classified as treasury stock on our condensed consolidated balance sheets at the payment date, though only shares physically delivered to us by June 1, 2018 were excluded from the computation of earnings per share. As of June 1, 2018, $211.2 million of prepayment remained under this agreement.

Subsequent to June 1, 2018, as part of the $2.5 billion stock repurchase authority approved in January 2017, we entered into a structured stock repurchase agreement with a large financial institution whereupon we provided them with a prepayment of $750 million. This amount will be classified as treasury stock on our condensed consolidated balance sheets. Upon completion of the $750 million stock repurchase agreement, $150 million remains under the $2.5 billion authority. We have not drawn from our new $8 billion authority as of the issuance of these financial statements.
