Yahoo's latest earnings report leaves no doubt the internet company is stuck in a downward spiral.
The company managed to beat Wall Street's limited expectations for revenue in the April-June quarter.
But after subtracting commissions paid to its partners, Yahoo said its revenue fell 19 per cent from a year earlier, while its loss widened to $US440 million ($A579.10 million).
Yahoo also reported on Monday that it's writing down $US482 million in charges related to the declining value of Tumblr, the social-blogging service that Yahoo acquired for $US1.1 billion in 2013.
Combined with an earlier write-down of $US230 million, that indicates Tumblr's value has plunged by almost two-thirds.

What remains unclear is whether Yahoo will abort its long-running turnaround attempts and sell its operations in a move that would likely end the four-year reign of chief executive Marissa Mayer.
Mayer had little to say about a possible sale on Monday, as she released the latest in a succession of dismal earnings reports. She told investors the company is carefully evaluating bids but added, "We have no announcement today."
The company began soliciting bids five months ago.
A decision may come soon, though. Monday was the deadline for final offers.
The list of prospective buyers includes two telecommunications providers, Verizon Communications and AT&T, which are hoping to broaden their array of digital services.
Also in the running is a group led by Quicken Loans founder Dan Gilbert with the backing of billionaire investor Warren Buffett. Several private equity firms that specialise in buying troubled companies are also believed to be in the running.
Analysts have estimated Yahoo will fetch $US4 billion to $US8 billion for a line-up that includes its email service and popular sections devoted to news, sports and finance. Most analysts expect the offers to come in the middle of the projected range.
If Yahoo jettisons its struggling internet operations, it will still retain prized stakes in Yahoo Japan and Chinese e-commerce leader Alibaba Group. Yahoo's investment in Alibaba alone is currently worth $US32 billion, before taxes.
