About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

AM Best Revises Issuer Credit Rating Outlook to Positive for Arch Capital Group Ltd. and Its Subsidiaries

By: via Business Wire

AM Best has revised the outlooks to positive from stable for the Long-Term Issuer Credit Ratings (Long-Term ICRs) and affirmed the Financial Strength Rating (FSR) of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) of Arch Reinsurance Ltd. (Arch) (Bermuda) and its strategic affiliates. Concurrently, AM Best has revised the outlook to positive from stable and affirmed the Long-Term ICRs of “a-” (Excellent) and the Long-Term Issue Credit Ratings (Long-Term IRs) of Arch Capital Group Ltd. (Arch Capital) (Bermuda) [NASDAQ: ACGL], the ultimate holding company; Arch Capital Group (US) Inc (Delaware); and Arch Capital Finance LLC (Delaware). (See below for a detailed listing of the companies and ratings.) The outlook of the FSR is stable.

The Credit Ratings (ratings) of Arch reflect the group’s balance sheet strength, which AM Best assesses as strongest, as well as its strong operating performance, favorable business profile and appropriate enterprise risk management (ERM).

Arch’s ratings, along with its Long-Term ICRs outlooks revision to positive from stable, are based on its historically strong operating performance. Though the reinsurance market has grown more favorable, particularly in the period after the January 1, 2023 renewal season, Arch has a proven track record, even in softer market years, of producing superior underwriting results and investment returns. In the recent market with more favorable underwriting conditions, the group continued to differentiate itself from its peers. A key factor in Arch’s success has been its three underwriting segments (reinsurance, primary insurance, mortgage insurance) and its unique agility in managing underwriting cycles.

Additionally, these ratings reflect Arch’s balance sheet strength assessment of strongest, as measured by Best’s Capital Adequacy Ratio (BCAR), and strong management team. Arch performed favorably in 2023, with the group producing record high earnings. Arch also has maintained its robust risk-adjusted capital position, which contemplates a significant stressed ultimate loss, as calculated by AM Best’s “Evaluating Mortgage Insurance” criteria procedure. AM Best utilized a conservative stress scenario for Arch’s mortgage insurance book of business when calculating stress-tested risk-adjusted capitalization. AM Best also recognizes that the mortgage insurance business relies heavily on financial models that can vary from actual results.

The positive outlooks on the Long-Term ICRs reflects AM Best's expectation that the group will continue to outperform its peers through profitable underwriting and robust investment returns, as it supports recent strategic acquisitions and continues to enhance its market position.
