Travel on L1B Visa expiring in 2014 and impact on I94 upon returning to US


I and my are on L1B visa with visa stamp expiring in April 2014 and I94 expiring in May 2015. We came to US in May 2012.

My question is If i want to travel to India In Dec 2013, will there be any impact on my I94? Will I get new I94 valid till April 2014 or it will stay the same as May 2015?

Please advice.
