Mom and Dad may be forced to ditch a trip to Sears and Kmart for toys this holiday season.

Jakks Pacific (JAKK) - Get Report CEO Stephen Berman said on a conference call Thursday the toy maker has opted to halt shipments to a "major U.S. customer that is experiencing challenges" to reduce risks to the company. The major U.S. customer is reportedlySears Holdings' (SHLD) struggling Kmart discount chain. 

As TheStreetrecently reported, toy makers fearful of not getting paid by cash-strapped Sears may be re-thinking how much they ship to the beleaguered retailer for the holiday season amid reports of a possible post-holiday bankruptcy filing.

"The mood in the toy industry is upbeat after two strong years of growth and a good start to 2016. The only concerns in the toy industry are minor ones: whether to ship to a troubled Sears/Kmart organization and if Hanjin shipping containers will be unloaded on time," wrote BMO Capital Markets analyst Gerrick Johnson in a note earlier this month.

Johnson's analysis arrived after a visit to the Dallas Fall Toy Preview, where he met with management teams from private toy companies. He then traveled to Los Angeles to meet with larger toy makers Jakks Pacific and Mattel (MAT) - Get Report . Johnson notes Sears likely represents about 2% of the U.S. toy industry at retail.

Spokespeople at Hasbro (HAS) - Get Report  and Mattel haven't returned repeated requests for comment on whether they have reduced holiday shipments to Sears. Sears spokesman Howard Riefs hasn't returned several requests seeking comment.

It would be hard to blame toy makers for approaching Sears with caution right now.

Fitch Ratings Managing Director Monica Aggarwal estimated Sears will burn through a shocking $1.6 billion to $1.8 billion in cash this year, fueled in large part by as much as $1 billion in earnings before interest, taxes, depreciation and amortization (Ebitda) losses. A year ago, Sears lost $837 million on an EBITDA basis, according to Fitch Ratings.

Fitch Ratings defines Sears' cash burn as cash flow from operations after taking into consideration capital expenditures and pension contributions. The result would make it eight straight years of cash burn for Sears, according to Bloomberg data.

Sears' cash and equivalents declined to a dangerously low $276 million in the second quarter from $1.8 billion a year ago. The company was forced to accept $300 million in financing from CEO Edward Lampert's investment vehicle ESL Investments in August in an effort to make it through the holidays. Sears' cash flow outlook remain bleak, too, for several reasons.

First, given the prospect for continued steep losses next year, Sears will likely have another operating cash outflow. Meanwhile, Fitch estimates Sears' interest expense, capital expenditures and pension outlays will tally $800 million, and it will need need $500 million to $650 million to fund seasonal working capital. Hence, it doesn't take a mathematician to figure out Sears needs to raise cash -- and do so fast if it wants to survive another year.

The concerning cash flow outlook has caused Fitch Ratings to sound the alarm bell on the once iconic retailer. Sears has "significant default risk" within the next 12 to 24 months, triggered by years of weak store traffic and high levels of debt, Fitch Ratings said in a redent report.

"Default risk means most likely a bankruptcy, or a Chapter 11 filing," said one of the report's authors, Sharon Bonelli, in a phone interview, meaning that the company will either have to liquidate to pay back its creditors, or reorganize in bankruptcy court and hope to stay alive by emerging as a smaller entity. At issue for Sears, which is battling declining cash flow amid a prolonged stretch of losses, is repaying some $2.8 billion in high yield bonds and institutional term loans coming due in the next few years.

Sears' "restructuring risk is high over the next 12 months, as our 'CC' rating would suggest," said Aggarwal.

Fitch joined Moody's Investors Service in voicing serious concerns about Sears. Moody's recently slashed its speculative-grade liquidity rating on Sears one notch to SGL-3 from SGL-2. The new rating reflects the likelihood that Sears will continue to need outside financing to stay in business, and that it may require covenant relief to maintain orderly access to funding lines.

"We recognize the risks associated with relying on these sources and continued shareholder support to finance its negative operating cash flow which is estimated by Moody's to be approximately $1.5 billion this year," said Christina Boni, a Moody's vice president.
