Cash and cash equivalents, short-term investments, and restricted cash and investment balances increased to $2.7 billion at the end of the December 2013 quarter compared to $2.6 billion at the end of the September 2013 quarter. This increase was primarily the result of approximately $129 million in cash flows from operating activities during the December 2013 quarter, partially offset by $48 million of stock repurchases.
Deferred revenue and deferred profit balances at the end of the December 2013 quarter increased to $405.0 million and $224.4 million, respectively, as compared to $334.0 million and $188.4 million, respectively, at the end of the September 2013 quarter. Lam's deferred revenue balance does not include shipments to Japanese customers, to whom title does not transfer until customer acceptance. Shipments to Japanese customers are classified as inventory at cost until the time of acceptance. The anticipated future revenue from shipments to Japanese customers was approximately $53.5 million as of December 29, 2013.
