The US-based company, which started a stock repurchase worth USD 2 billion in June 2012, bought about USD 1.3 billion of shares.
"The stock repurchase programme is intended to offset the impact of dilution from our equity compensation programmes," the firm said last week.
As of December 31, the company had about USD 640 million pending for repurchases of its common stock under the 2012 programme, it said in a filing with the US Securities and Exchange Commission (SEC).
Last month, the company's board of directors authorised an additional USD 5 billion stock repurchase programme.
The new stock repurchase programme, together with USD 640 million remaining, brings the total repurchase authorisation as of January to USD 5.6 billion, eBay said in the filing.
eBay also expects to make opportunistic repurchases of its common stock to reduce the outstanding share count.
"Any share repurchases under our stock repurchase programmes may be made through open market transactions, block trades, privately negotiated transactions or other means at times and in such amounts as management deems appropriate and may be funded from our working capital or other financing alternatives," it added.
The global commerce platform and payments firm said its fourth quarter revenue rose 13 per cent to USD 4.5 billion from a year earlier. Net income in the quarter stood at USD 850 million, driven primarily by strong top-line growth.
The total company-enabled commerce volume increased 22 per cent in the fourth quarter to USD 61 billion.
Both Marketplaces and PayPal achieved record mobile results in 2013, each exceeding USD 20 billion.
Mobile users represented 40 per cent of eBay's 36 million new users and accounts in 2013, contributing USD 35 billion to commerce volumes.
