Google has warned that it may be forced to make more redundancies than first thought in its bid to reduce the burden on its financies from its Motorola subsidary.
Google announced it was revising its original forecasts in an amended filing with the US Security Exchange Commission on Thursday.
"Motorola has continued to refine its planned restructuring actions and now expects to broaden those actions to include additional geographic regions outside of the US," read the filing.
"Motorola continues to evaluate its plans and further restructuring actions may occur, which may cause Google to incur additional restructuring charges, some of which may be significant."
The search giant clarified that it now expects to incur $300m severance-related charges, an increase from its original $275m estimate.
The cuts originally saw Google planning to cut around 20 percent of Motorola Mobility's staff, some 4,000 workers, when first announced in August.
There is currently no word how many more staff will lose their jobs under the revised plan and neither Google nor Motorola had responded to V3's request for clarification at the time of publication.
Google purchased the mobile wing of Motorola for $12.5 billion in 2011, which was seen at the time as a protective move to gain access to its extensive patent portfolio in the growing legal battles in the market.
The company said it did not believe the move would affect its relationship with other mobile phone makers using its Android operating system.
The restructure will reportedly result in Motorola producing fewer devices and instead focusing on higher quality handsets. HTC announced a similar move in 2011, just before it unveiled its new One series of smartphones.
