Here is the letter AOL CEO Randy Falco (pictured here) has penned to the entire staff about layoffs of 10 percent of its workforce–or 700 people–and other cost cuts, which the online service is announcing today.

“We’re at a pivotal point in AOL’s transformation, and need to be even more strategically focused and operationally efficient as we weather the economic storm,” wrote Falco, in part, about the move.

As BoomTown reported earlier today, Time Warner (TWX) online unit AOL is making huge staff cuts, due to the weak economy and the ensuing deep falloff in advertising revenue, but also because of recent structural changes made to refocus the once-mighty service.

The layoffs will take place over the next several quarters, with most of the U.S. cuts to be completed by March. AOL has 7,000 employees world-wide, with most located domestically.

Here’s Falco’s letter:

Dear AOL colleagues,

I’m writing to tell you about some important decisions we’ve made about AOL’s business and why we’ve made them.

The deepening economic recession has affected every corner of the economy, including our own. Online marketers have tightened their ad buying across the board, reducing their spend by hundreds of millions of dollars.

As a result, we will be reviewing our entire organization to further align resources and expenses against the real revenue opportunities in this difficult market. Part of this will involve consolidating groups to gain efficiencies that will unfortunately lead to head-count reductions. We anticipate this will result in a net reduction of our workforce of up to 10% over the next several quarters–and we will attempt to finalize all domestic actions by the end of March. Reducing our workforce is never easy, particularly in the current climate, but our goal in doing this is to provide our core businesses the resources they need to thrive. Please know that, as always, we’ll be doing everything we can to help and support those affected, including offering severance packages and other services.

To further keep employment costs down, we will also forgo merit pay increases in 2009. This is a painful decision, but one that many companies have prudently taken to help minimize the number of layoffs they have to make.

To provide some perspective on these decisions, right now we’re two years into a three-year turnaround plan. Since day one, our strategy has focused on building and growing mutually dependent publishing, advertising and social media businesses to take advantage of the shifting media landscape. We’ve worked shoulder-to-shoulder to make considerable progress during this time.

We acquired best-in-class companies across the digital advertising space (AdTech, Third Screen Media, Lightningcast, buy.at, TACODA and Quigo, respectively) and integrated them with Advertising.com to build Platform-A, the largest, smartest display advertising platform in the world.

We grew our MediaGlow audience via an efficient content development model that in 2008 enabled us to launch more than 20 new sites that are generating significant page view (up 64% year over year in December), engagement (up 39% year over year) and unduplicated user (70+ million) numbers. This momentum will continue in 2009 with our goal of creating an additional 30+ editorially curated sites focused on consumer passion points.

We combined Bebo with our longtime community assets AIM and ICQ as well as newer acquisitions Goowy, Yedda and SocialThing, to build People Networks, gaining AOL a foothold in the critical social media space, with more announcements to come on the next phase of development in both the social media space and in the integration of social and publishing capabilities.

This progress continues to put AOL in a strong position to capitalize on our new business model when the recession ends.

In addition to focusing our investments, a successful turnaround plan also requires us to realign our cost structure against this three-pronged business model–making difficult decisions to cut costs in areas that aren’t critical to our growth. Splitting out the Access business improved the transparency of what’s working and what’s not, and allowed us to make better decisions about exiting businesses that weren’t performing while investing in growth areas. A successful turnaround plan also mandates we control costs, operate with healthy margins and position the company for sustainable growth. As you know, we’ve moved repeatedly to bring discretionary expenses in line to spare across-the-board job cuts.

But we’ve also had to make many hard decisions along the way. And this moment is no exception. We’re at a pivotal point in AOL’s transformation, and need to be even more strategically focused and operationally efficient as we weather the economic storm.

In addition to the head-count reductions and the 2009 merit pay decision, we are also making changes throughout the organization to improve efficiency and better align it to our three core businesses. This includes a review of our international operations and our global shared-services functions. In addition, we will continue throughout the year to carefully and thoroughly review all our products and services to make sure every one fully supports our strategy and has the potential for growth.

Finally, we are going to realize significant savings by continuing to consolidate our facilities–for example, moving from two buildings to one in Mountain View, from two floors to one in Los Angeles, and leasing unused space on our Dulles campus.

With these and other changes, we will take significant annual run-rate costs out of our business while, importantly, retaining the flexibility to invest in our growth strategy.

I know all this will raise questions, but I wanted to share as much as I could with you now. Senior management will provide more details as appropriate to their teams in the weeks ahead.

As difficult as things look right now, the economy eventually will turn around. Some companies will use this time prudently and make difficult decisions to come out of it in better shape–growing toward areas of opportunity, scaling back in others and maintaining a line on costs all around. Our only choice is to be one of these companies. With your continued hard work and dedication, we will position ourselves to emerge a stronger company ready to lead in a vibrant online market.

Randy
