Household Bank acquired a failed Colorado thrift.

The takeover of insolvent Brighton Savings & Loan Assn., with $92 million in assets, is Household’s second acquisition of a collapsed S&L; this year and its fourth in less than 16 months. Household, a Westminster-based savings bank subsidiary of Household International Inc., has $850 million in assets and now operates S&Ls; in Colorado, Illinois, Maryland and Ohio, as well as in California. The Federal Savings and Loan Insurance Corp. paid Household $22 million to assume Brighton’s liabilities and operate its two offices.
