LONDON -- Royal Bank of Scotland (LSE: RBS.L) (NYSE: RBS) kept steady at 263 pence in early trade this morning after the bank announced its Direct Line (LSE: DLG) insurance subsidiary is to be sold for 175 pence per share.

The FTSE 100 (UKX) member confirmed up to 518 million shares in Direct Line would be offered to investors. The flotation is expected to raise gross proceeds of at least 787 million pounds for RBS.

Direct Line's market cap at 175 pence a share will be 2.6 billion pounds, which would place the insurer toward the top of the FTSE 250 index and just outside the FTSE 100.

Direct Line shares will begin full trading on the main market on Tuesday, 16 October. Conditional dealings in the shares, whereby institutions trade on the basis of settlements being made after the flotation, started today at 8 a.m.

Following admission, RBS will retain a 65%, or 1.7 billion pounds, stake in Direct Line. The insurer's mangers will own shares with an aggregate 760,000-pound value.

RBS is essentially a forced seller of Direct Line. The flotation is the first step to satisfying the disposal commitment made to the European Commission after the bank received a taxpayer-funded bailout during 2009. RBS must sell its remaining 65% stake in Direct Line before the end of 2014.

Commenting on today's announcement, Paul Geddes, chief executive of Direct Line, said:

We are delighted with the level of demand institutional and retail investors have shown in Direct Line Group, reflecting the recognition of our clear strategy and key strengths of distribution, scale and market leading brands. We look forward to life as a publicly listed company with the support of a strong and diverse shareholder base.

Direct Line may offer prospective investors some attractive features. In particular, the business claims to have a market-leading position in both home and motor insurance, with an 18% share of each and a total of 8.5 million in-force policies.

Furthermore, the business intends to pay between 50% and 60% of its post-tax profits as a dividend, as well as adopt a "progressive" payout policy thereafter. Direct Line has said it expects to pay its first dividend in the second quarter of next year.

Direct Line's impending flotation could be one to watch, as industry rival Admiral (LSE: ADM) rallied from a start price of 275 pence to as high as 17 pounds after its 2004 listing.
