ACCIDENTS of history make BG 
				shares look decidedly expensive. As a remnant part of the 
				British Gas privatised by Baroness Thatcher, it may still be 
				assumed that BG is one of those steady-as-she-goes blue chips 
				that sits comfortably in a widows-and-orphans equity portfolio. 
				At the same time, it is tempting to consider BG within a peer 
				group encompassing oil majors such as BP and Shell. BG is 
				different to BP and Shell because it is about gas, not oil, but, 
				bereft of anything else, BG, BP and Shell constitute respectable 
				comparators. 
				Yet BG shares, judged with reference to the prospective 
				p/e ratio of 14.5 and dividend yield of less than 11 per cent, 
				are expensive beside both these peers. BT shares, for example, 
				trade on a cheapish prospective p/e ratio of 11.5 and give a 
				dividend yield of 5.5 per cent. Shares in Centrica — BG’s twin 
				offspring from British Gas — trade on a not-so-cheap p/e ratio 
				of 13, but give a 4.6 per cent dividend yield that gives the 
				stock notable value characteristics. Shares in BP and Shell, 
				meanwhile, hover on p/e ratios of about 10.5 and give dividend 
				yields of 3.3 and 3.6 per cent respectively. 
				
				Takeover speculation, much discussed but scantly evidenced, 
				partly explains the BG share-price premium. It also partly 
				explains why the shares have gently but steadily outperformed 
				the oil and gas sector, as shown in the graph, over the past 
				three years. There is a more convincing explanation, however. 
				Rather than seeing BG as a relatively small privatisation stock 
				or oil and gas blue chip, it may be more useful to see it as a 
				relatively large exploration and production (E&P) play. If one 
				considers BG’s peers to be the likes of Cairn Energy and Tullow 
				Oil, the shares look reasonably valued. Cairn stock trades on a 
				prospective p/e ratio of 76 and gives no dividend. Shares in 
				Tullow, which may be a better comparator since it has more 
				producing assets, sit on a p/e of 13.5 and give a 1 per cent 
				dividend yield. 
				Yesterday’s trading statement from BG should settle the 
				nervousness created last month when a decision to buy back £1 
				billion of shares was interpreted as suggesting that the company 
				as running out of growth ideas. The more obvious interpretation 
				is that the buyback shows that BG is producing more cash that it 
				can sensibly invest. And it is a good sign. 
				In the context of E&P plays, BG shares are not expensive. 
				But, as with all E&P plays, the potential for added return comes 
				with added risk. Hold.
