Net Cash Provided by Investing Activities. Net cash provided by investing activities decreased $94,623 to $105,056 for the year ended December 31, 2003 from $199,679 for the year ended December 31, 2002. The decrease was primarily due to the $116,130 net effect of purchases and maturities of marketable securities and maturities of restricted investments. In addition, capital expenditures decreased to $20,118 for the year ended December 31, 2003 from $41,625 for the year ended December 31, 2002, as we substantially completed the build-out of our terrestrial repeater network during 2002.
