Our parent, DISH Network, provides a centralized system for the management of our cash and marketable investment securities as it does for all of its subsidiaries to, among other reasons, maximize yield of the portfolio. As a result, the cash and marketable investment securities included on our Consolidated Balance Sheets are a component or portion of the overall cash and marketable investment securities portfolio included on DISH Network’s Consolidated Balance Sheets and are managed by DISH Network. We are reflecting the purchases and sales of marketable investment securities on a net basis for each period presented on our Consolidated Statements of Cash Flows as we believe the net presentation is more meaningful to our cash flows from investing activities.
