March 7 (Reuters) - Broadcom Ltd sought again to soothe U.S. security concerns around its bid for chipmaker Qualcomm Inc on Wednesday, saying it would stick with investments aimed at maintaining the United States' leadership in 5G technology.
The Committee on Foreign Investment in the United States (CFIUS), a national security panel that can stop mergers that could harm U.S. security, in an unusual move, stepped into Singapore-based Broadcom's hostile takeover bid for Qualcomm this week, citing a number of concerns on the development of the next generation of mobile networks and technology.
CFIUS delayed a shareholder meeting that had threatened to hand Broadcom control of the Qualcomm board and, among other things, said lower R&D spending would weaken U.S.-based Qualcomm against Chinese companies.
Here are the important events that have taken place since Broadcom made its first bid to buy Qualcomm:
March 6, 2018
CFIUS identified potential risks that warrant a full investigation of Broadcom's $117 billion bid for Qualcomm, a senior U.S. Treasury official said in a letter to the companies.
Some of the U.S. government's concerns relate to risks associated with Broadcom's relationships with foreign entities, Aimen Mir, the Treasury's deputy assistant secretary for investment security, said in the letter, without identifying who those parties might be.
The letter, dated March 5, was made public by Qualcomm on Tuesday.
Separately, the Wall Street Journal reported that Qualcomm is in talks to settle a patent dispute with China's Huawei Technologies Co and could reach an agreement in the coming weeks, citing people familiar with the matter.
March 5, 2018
Broadcom said the decision by CFIUS to review the deal was the result of secret moves made by Qualcomm on Jan. 29 to encourage an investigation into the offer.
Qualcomm said in a statement that it was delaying its 2018 annual meeting to April 5 as a result of the CFIUS order.
Separately, Qualcomm, which is awaiting China's MOFCOM approval for the $44 billion deal to buy NXP Semiconductors NV , extended the tender offer to March 9 from March 5.
March 4, 2018
The U.S. government ordered the national security review of Broadcom Ltd's $117 billion bid for Qualcomm that prompted Qualcomm to delay its March 6 shareholder meeting.
March 2, 2018
Broadcom, seeking to buy rival Qualcomm, was planning to complete its move back to the United States by mid-May, Reuters reported, citing sources familiar with the matter.
Wrapping up the move from Singapore and redomiciling in the United States relatively quickly could remove a roadblock to Broadcom's proposed deal by calming concerns at the national security panel, CFIUS.
Feb. 27, 2018
CFIUS began looking at Singapore-based chipmaker Broadcom's plan to take over rival Qualcomm, Reuters reported, citing three sources familiar with the matter.
Feb. 26, 2018
Qualcomm appears to warm to Broadcom's advances by saying the sides have grown closer on regulatory issues and called for talks on price after Broadcom's latest $117 billion offer. The war of words continued, however, as Broadcom called its U.S. semiconductor peer's proposal to negotiate a higher price "engagement theater".

Feb. 5, 2018
Broadcom raises its offer for Qualcomm to $82 per share from $70 per share, calling the bid its "best and final offer". The revised offer is contingent on either Qualcomm acquiring NXP Semiconductors for $38 billion or the NXP deal being terminated.
Jan. 17, 2018
The Federal Trade Commission investigates whether Broadcom engaged in anticompetitive tactics in negotiations with customers, casting further doubts on regulatory approval for potential deals.
