Uber is reportedly operating at a loss of close to half a billion dollars, according to a bond prospectus viewed by Bloomberg.

The Bloomberg report showed $470 million in operating losses with $415 million in revenue, but the report said it was not clear whether the numbers were the results of one quarter, a full year, or some other time period. Nor does it say when the financial numbers are from.

"These are substantially old numbers that do not reflect business activities today," an Uber representative told Business Insider. The company declined to clarify the time period or time frame for the numbers, but it has said the prospectus was not being distributed by Uber.

Last week, The Wall Street Journal reported that the ride-hailing app was raising new funding from the Chinese investment management firm Hillhouse Capital Group. It was rumored that the amount could be as high as $1 billion, though another source told The Journal the final investment was likely to be "hundreds of millions of dollars."

The investment with Hillhouse could be a sign Uber is thinking of going public soon.

The Chinese investment firm was rumored to be purchasing bonds that would later convert into shares at a discount to Uber's initial-public-offering price. The Journal pointed out that the deal with Hillhouse encouraged Uber to go public soon, because the bonds rise in value the longer Uber waits.
