With losses mounting and online and offline sales declining, Neiman Marcus announced on Tuesday morning it is exploring the possibility of a sale.

In its fiscal second quarter earnings filing, Neiman Marcus reported a $117.1 million net loss during the quarter ended Jan. 28, compared to a $7.9 million profit during the same period last year. Through the first six months of fiscal 2017, Neiman Marcus posted a $140.6 million total loss, compared to a $2.7 million loss during the same time last year. Those figures both include a $153.8 non-cash impairment charge which Neiman Marcus writes is related to the revaluing of its brand assets.

While the retailer’s overall sales fell 6.1% during the quarter, its online sales fell 0.4%, which meant that online sales for Neiman Marcus, No. 36 in the Internet Retailer 2016 Top 500 Guide, accounted for a larger share of the retail chain’s total revenue during the quarter.

In its 10-Q filing with the U.S. Securities and Exchange Commission on Tuesday, Neiman Marcus reported that e-commerce accounted for 31.4% of its total sales during the second quarter, or $438.2 million, down from $440.1 million during the same period last year, when online sales accounted for 29.6% of total revenue. For the first six months of fiscal 2017, e-commerce accounted for 30.5% of total revenue, or $754.8 million, down slightly from $755.8 million last year, when online sales accounted for 28.5% of total revenue.

CEO Karen Katz said those figures could’ve been higher had it not been for ongoing issues with NMG One, the retailer’s cross-channel merchandising and distribution system that launched during the first quarter which is designed to streamline its operations across all of its channels. Katz estimated that so far this year, the system’s implementation issues have cost the company at least $55-65 million based on available data.

“We believe the full impact on our sales is likely greater because there is a number of ways that our business has been disrupted that we cannot directly track or measure,” she said. “For example, the impact of not displaying the right product online or not getting product through our distribution centers to our stores as fast as we normally do. We expect this top line pressure to lessen as the system becomes fully operational.”

Katz said in some cases products aren’t showing up correctly online because the new system marries together data from three, 40-year-old systems, which has meant that some SKUs aren’t recognized by the new singular system.

“To give an example of how this manifested itself, a shoe that comes in three colors showed up as three individual shoes in three different places on the website rather than one shoe in three colors displayed in one place,” she said. “It prevents customers from having a seamless online shopping experience.” Katz said the company has identified and isolated the issues and should have all issues related to NMG One resolved by the end of the current fiscal year.

For the second quarter ended Jan. 28, Neiman Marcus reported:

• Total sales of $1.396 billion, down 6.1% from $1.487 billion during the same time last year.
• A year-over-year comparable sales decline including e-commerce of 6.8%, compared to a 2.4% decline during the same time last year.

For the first six months of fiscal 2017, Neiman Marcus reported:

• Total sales of $2.475 billion, down 6.7% from $2.652 billion last year.
• A year-over-year comparable sales decline of 7.3%, compared to a 3.8% decline last year.
