Happy Holidays to All…

It has been an eventful year in every respect. At year end, as I reflect on our work to date, I couldn’t be more proud of what we have accomplished. Many of our accomplishments have come in the face of a strategic review which, in my humble opinion, has developed into a fantastic outcome for Weyerhaeuser AND WRECO; and all done safely.

Every one of you played an important role in our success this year and I know it took time away from your families to accomplish. Thank you for your continuing commitment to the WRECO family. I think we all believe that under any circumstance it’s a great collection of companies, brands and people, and your appreciation for the power of that legacy has allowed us to do great things this year.

As promised, I want to update you on our progress regarding the transition from WRECO to TRI Pointe. While we have a signed agreement, there is still much work to do in closing a transaction of this size. It was only 45 days ago that we announced the transaction, but the wheels have begun to turn as to the transition planning. During this process, we continue to be limited in what we can communicate. I would remind everyone that communication directly with TRI Pointe is not permitted and we must continue to observe our business ethics discipline, in effect treating them like a competitor until the transaction is closed. Our work at WRECO has been focused on planning for the mechanics of an operational transition to insure the backbone systems of IT, HR, Accounting, Treasury and Legal (to name a few) are in place for a successful transition. The goal is to “unplug” from the Weyerhaeuser infrastructure and be fully operational under TRI Pointe on day one. While there are no firm dates for closing at this time, the teams are working toward closing in the second quarter.

One of the most gratifying elements of this transaction is TRI Pointe’s acknowledgement of the power of our brands and independent company approach. As such, the transition planning work has been focused primarily at the WRECO level as we organize for the “unplugging” of major systems from Weyerhaeuser to insure we are fully functional on day one. Yes, over time, there will be adjustments in basic processes as we integrate with TRI Pointe after closing. But the value set is clear and I like where we are heading – the “business as usual” mantra still rings true.

I know each of you have questions about how this transition will affect you personally and we are working on answers to those questions. Later today, we will post a set of questions and answers on the WRECO SharePoint site under the TRI Pointe Transition tab available at the following hyperlink:

http://wss.weyer.com/sites/wreco/TriPointeTransition/Forms/AllItems.aspx.

My aim is to keep it updated with answers to the most frequently asked questions as answers become available. If you have particular questions that are unique to your personal situation, your best course of action is to discuss them with your local HR representative. They will do their best to get you answers in a timely way, subject to information availability.

Here are some facts I know for sure…




While the Weyerhaeuser vested benefits you have earned will remain yours, we will no longer participate in a pension program. However, our total benefits package will be substantially comparable. According to the transaction agreement, for a period of at least a year, TRI Pointe will provide the employees of WRECO and its subsidiaries with salary and bonus opportunities that are no less favorable than those provided by WRECO and substantially comparable benefits to those provided by WRECO. The FAQs mentioned above will address more specific questions concerning benefits and other compensation related matters.
We will maintain the structure of the bonus programs for 2014 and adjust our key measures, as we do every year, for our 2014 expectations.
TRI Pointe has advised us that its current plan is to continue the Maracay, Pardee, Quadrant, Trendmaker and Winchester brands and operations.
We are still in the business of buying new land to support our growth goals.
The TRI Pointe Homes headquarters are in Irvine, California, and the WRECO team is clear that not everyone can, or will, be asked to relocate to TRI Pointe headquarters.

Safely selling, building and closing homes must remain our focus through the balance of 2013 and beyond. WRECO does it better than anyone and I have every confidence we will meet our goals. Thank you again for the unbelievable efforts during 2013 in the face of a challenging environment. I hope each of you have a wonderful holiday season with family and friends.
