Historically, major tech firms have shunned debt financing, but in recent years, this has changed somewhat. Highly acquisitive companies like Cisco and Oracle have started to use some debt to finance their purchases
. As with the increasing presence of private equity in the tech industry
, low interest rates have helped fuel this trend. But the low interest rate environment appears to be coming to an end, and its effects are already being felt in the industry. Yesterday, online travel site Expedia announced that it would suspend a planned share buyback program because it couldn't acquire the necessary capital to finance the purchases
. Meanwhile, a few non-tech private equity deals are hitting the skids
for similar reasons. In the past, industry, might have ignored these economic developments, but it's likely that a number of companies, particularly mature ones, are going to feel a pinch.
