The WSJ and Barron's will offer an unusual guarantee to print advertisers who take out an ad between April 1 and June 30, the company told Adweek in an exclusive.

The ad must achieve at least a 70% recall rate, a benchmark measured by Research and Analysis of Media (RAM), a third-party international research firm. If it doesn’t, those advertisers will be offered the same-size ad and placement for free within two weeks of the original ad’s run date.

Rubicon Project and Telaria closed their merger this morning, officially forming the largest independent supply-side platform on the market.

The company, which will announce a new name in the coming months, is coming together during the coronavirus pandemic that has put a strain on the global economy and caused ad budgets to shrink.

Following the completion of the deal, the combined company has $143 million cash on hand, and no debt. Michael Barrett, CEO of Rubicon Project, said having such a strong balance sheet is fortunate in these financially uncertain times.

The holding company said it is freezing new hires, reviewing freelance spend and stopping “discretionary” costs, which include travel, hotels and awards show payments. WPP is also postponing planned salary increases for 2020.
