Time Inc. (TIME) , which halted an exploration of a sale of the entire company earlier this year, has updated its divestiture plans and revealed planned changes to its credit agreement.

The New York publisher in a Form 8-K filing on Friday, Sept. 22, with the Securities and Exchange Commission, said it has identified Time Inc. UK Ltd., fulfillment services arm Time Customer Service Inc., a majority stake in Essence and its Coastal Living, Sunset and Golf brands for potential divestiture.

Time said a transaction could come as early as the fourth quarter but noted it could not assure whether the divestitures would carry acceptable terms or occur at all. No definitive agreements have been struck for any potential sale, and the processes are at different stages.

Time estimated the assets on the block contributed $488 million, or 17%, to its revenue for the 12 months ended June 30.

Time shares on Friday afternoon were down 7 cents, or 0.6%, to $12.48. Shares have fallen 30.1% in 2017, thanks in part to a plunge after the sale process ended.

Following a first-quarter conference call in May, Time CEO Rich Battista told TheStreet that noncore sales for the publisher could include any of Time's titles or its various businesses such as a books division and an assortment of marketing and advertising groups.

"The reasoning here is to enhance our strategic and financial flexibility," Battista said then. "This is really about being smart about how we maintain a strong balance sheet and allowing us the monies to invest going forward."

Battista in July told Bloomberg the company was looking to sell Coastal Living, Sunset and Golf, around the same time The Wall Street Journal reported the potential sale of the Essence stake.

Essence as of Dec. 31 had a rate base of 1.05 million -- the circulation guaranteed to advertisers. Golf and Sunset had respective rate bases of 1.4 million and 1.25 million, according to Time's latest annual report, which did not list the rate base for Coastal Living. People (3.4 million), Time and Sports Illustrated (both 3 million) sport the company's highest rate bases, followed by Southern Living (2.8 million) and Real Simple (1.98 million).

Friday's 8-K adds to the assets on the block Time Inc. UK, owner of brands including NME, Horse & Hound, Shooting Times and Rugby World. Time, then part of AOL Time Warner Inc., acquired U.K. magazine publisher IPC Group Ltd. in October 2001 from Cinven Partners LLP for $1.6 billion, or an estimated 13 times its enterprise value to Ebitda. IPC took the Time Inc. UK name in 2014.

Time decided to end a sale process in April after six months and instead focus on its strategic plan. A round of layoffs followed in June aimed at cutting costs.

The company, meanwhile, also said Friday it would seek to amend its credit agreement and issue up to $300 million in unsecured notes due 2025.

Time said it would use the proceeds from the new notes to pay down $200 million of its term loan and to reduce the term loan, existing unsecured notes or both by a total of $100 million. Time owed $575 million on the notes and $664 million on the term loan as of June 30, SEC filings show.

The amendment also would extend the maturity dates on its term loan and a $500 million revolving credit agreement with no balance by 3-1/2 years and reduce the commitment on the latter to $300 million.

The publisher did not indicate a time frame for the debt amendment and note issuance, and a Time representative could not be reached for immediate comment.
