This week, the Business Journal decided to focus most of its coverage on the wildfires that devastated our county this month.

In the days after the fire, it was estimated that there was more than $50 billion in damage. Now some loss estimates are as high as $150 billion.

And experts say the impact could be even larger.

On pages 4 and 5 we look at how a number of industries have been impacted.

We also take a deeper look on pages 47 and 48 about how busy the rental market has been as well as the future of the insurance industry in California.

Since the fires broke out, a number of businesses around L.A. have donated money.

Burbank-based The Walt Disney Co., for example, has committed $15 million for response and rebuilding efforts. The money is supporting organizations such as the American Red Cross, the Los Angeles Fire Department Foundation and the Los Angeles Regional Food Bank.

Bob Iger, the company’s chief executive, said Disney was “committed to supporting our community and our employees as we all work together to recover and rebuild from this unbelievable devastation.”

“Walt Disney came to Los Angeles with little more than his limitless imagination, and it was here that he chose to make his home, pursue his dreams and create extraordinary storytelling that means so much to so many people around the world. We are proud to provide assistance to this resilient and vibrant community in this moment of need,” he added.

SAG-AFTRA has donated $1 million to the SAG-AFTRA Foundation to assist members experiencing hardship caused by the fires.

Amgen and the Amgen Foundation, based in Thousand Oaks, meanwhile have committed $10 million for disaster relief.

The Amgen Foundation is also matching employee donations toward disaster relief.

“Southern California has been Amgen’s home for more than four decades and we are standing tall to support our community through this difficult time,” Robert A. Bradway, chair and chief executive of Amgen, said in a statement.
