NOTE L-STATEMENT OF CASH FLOW INFORMATION

Cash and cash equivalents at December 31, 2011 and 2010 included $122,000 and $186,000, respectively of restricted cash related to collateral on seismic operations bonds. The balance at December 31, 2011 also included $125,000 (Canadian) of restricted cash posted as security against Company issued credit cards for Olympic.

For purposes of the statement of cash flows, the Company considers all highly liquid investments or debt instruments with an original maturity of three months or less to be cash equivalents. The Company maintains its day-to-day operating cash and temporary excess cash with various banking institutions that, in turn, invest in time deposits and U.S. Treasury bills.

Significant non-cash investing and financing activities are as follows:

The Company had non-cash additions to its seismic data library comprised of the following (in thousands):

During the year ended December 31, 2009, the Company reversed a non-monetary exchange valued at $1.3 million that was originally entered into in 2008. The Company was notified that the client was unable to provide clear title to one of the seismic surveys included in the original contract resulting in the negative amount of non-monetary exchanges from underwriting of new acquisition in the 2009 period. This portion of non-cash underwriting was subsequently satisfied with a cash payment.
