(Reuters) — SoftBank’s talks to secure $3 billion from Japan’s three biggest banks have stalled as the lenders hit internal lending limits, two people said, complicating a $9.5 billion rescue package for WeWork.

The Japanese technology conglomerate is now likely to enter the new year without the WeWork financing in place, these sources said, adding that the banks are also concerned about the risks involved in rescuing the U.S.-based office sharing startup.

Mizuho Financial, Mitsubishi UFJ Financial Group, and Sumitomo Mitsui Financial Group are seeking ways to provide the financing while offsetting exposure, the sources said, declining to be identified because the information is not public.

SoftBank did not respond to a request for comment. Mizuho, MUFG, and SMFG likewise declined to comment.

One option is to use some of SoftBank’s 26% stake in Chinese ecommerce giant Alibaba Group as collateral, the sources said.

“SoftBank is an important client, so we want to do everything we can to help, but we have to consider our credit risk,” said a senior banker.

The talks illustrate the difficulty SoftBank poses for Japan’s banks. Founder Masayoshi Son’s tech juggernaut has long been a lucrative source of corporate lending in the world’s third-largest economy, where banks typically have to lend at ultra-low interest rates, given years of deflation.

But SoftBank’s growing debt and turmoil at WeWork earlier this year also highlight the firm’s higher risk profile.

“Banks cannot loosen their credit criteria only for SoftBank,” said S&P Global Ratings senior director Ryoji Yoshizawa.

Another option to spread the risk is a syndicated loan, Yoshizawa said, adding that this would be time-consuming and potentially delay financing.

Debt pile

SoftBank said in October that it would launch a $9.5 billion bailout of WeWork after the cancellation of the startup’s initial public offering due to investor concerns over its corporate governance and cofounder Adam Neumann’s hard-partying ways.

Son has said he turned a blind eye to Neumann’s management but that the company is still a solid business.

The domestic bank deadlock led SoftBank to secure a $1.75 billion line of credit from Goldman Sachs Group, the sources said.

Goldman Sachs declined to comment.

SoftBank has 5.5 trillion yen ($50.28 billion) in outstanding bonds and another 4 trillion yen in bank loans, Refinitiv data showed. Its weighted average cost of debt is 3.7%, the seventh-highest among all companies on the Nikkei 225 Stock Average.

Moody’s calculations showed the conglomerate’s interest coverage ratio is 1.3, meaning group income is enough to service its debt, with some left over.
