Therefore, the greater a risk weighting for a certain asset, the less attractive the asset becomes for a bank that already has a low capital-adequacy ratio.
Although the BIS has assigned the zero-risk weighting to the bonds of the governments of the Organization for Economic Cooperation and Development (OECD), the Basel Committee in 2001 proposed assigning a 20% weighting to bonds whose ratings are in the single-A class or below.
The officials said most countries will use their own domestic risk weighting rules for their government bonds.
First note that 0-1WEIGHT is clearly in NP, since one can verify in polynomial time for a given graph whether a weighting of its edges from {0, 1} is proper.
Note that any proper weighting w from {0,1} of a graph with such a triangle must hold w(xa) = w(xb); otherwise xw (a) = w(ab) + w(ax) = w(ba) + w(bx) = xw (b).
Note that in any proper weighting w from {0,1}, w(vx) [not equal to] w(vy); otherwise, as both xw(x) and xw(y) have k - 1 contributed by x and y's triangles, xw(x) = w(xv) + w(xy) + k - 1 = w(yv) + w(yx) + k - 1 = xw(y).
Fact 2.1 In h(G) the following holds: any proper weighting w from {0,1} satisfies xw (v) [member of] {n - 1, n, n + 1} for every v [member of] V.
