Wells Fargo Institutional Retirement and Trust is promoting America Saves Week via its Twitter account. The company will tweet retirement planning tips and advice throughout the week, including, "Don't wait to save" and "We understand that saving isn't always easy. Take a few minutes to find ways to invest for your future."

"Our research shows that Americans are critically under-saving for retirement, a huge problem at the personal and national level," said Laurie Nordquist, director of Wells Fargo IRT. "We want people to think about producing a nest egg that will replace 80 percent of their pre-retirement income. And we continue to look for innovative ways to make retirement planning top-of-mind. It's exciting to take part in America Saves Week 2012 and connect with followers through Twitter."

In addition to daily tweets on @Ask_WellsFargo, Wells Fargo's Beyond Today  blog will answer questions on topics ranging from how to start a retirement plan to knowing how much is enough to retire and will feature a blog posting from Laurie Nordquist in conjunction with America Saves Week.
