Correction of Statement of Cash Flows [Abstract] |
Correction of Statement of Cash Flows | Correction of Statement of Cash Flows. Subsequent to the issuance of our condensed consolidated financial statements for the three and six months ended June 30, 2011, we determined that certain balances within the consolidated statement of cash flows for the six months ended June 30, 2011 were misstated due to the amount of the change in property and equipment purchases in accounts payable for the six months ended June 30, 2011 used to determine the capital expenditures for property and equipment and the adjustment to trade payables necessary to arrive at net cash provided by operating activities having been inaccurately calculated. As a result, the affected line items under cash flows from operating activities and cash flows from investing activities of the consolidated statement of cash flows for the six months ended June 30, 2011, have been restated as follows (in thousands):
| As Previously Reported |  | As Corrected
Changes in operating assets and liabilities, net of effects from acquisitions: |  |  |
Trade payables | $ | (4,726 | ) |  | $ | (2,817 | )
Total adjustments | 96 |  |  | 2,005 |
Net cash provided by operating activities | 13,607 |  |  | 15,516 |
Capital expenditures for property and equipment | (21,642 | ) |  | (23,551 | )
Net cash used in investing activities | (24,493 | ) |  | (26,402 | )
The restatement impacted only line items within our consolidated statement of cash flows, and did not result in any change in the beginning and ending balances of cash and cash equivalents from the amounts previously reported. The restated line items do not have any impact on the consolidated balance sheets or statements of income for any period. We do not consider the foregoing corrections to be material.
