CPAs today need to be business consultants, advisors, planners and strategists. We need to be knowledgeable not only in accounting and tax law, but also in business analysis and valuation, estate planning, employee benefit administration and much more.

In August, our Health & Wellness Committee coordinated a day of outdoor fun at Mount Sunapee to celebrate those who participated in our Tax Season Monthly Move Challenge! ⛰

The whole firm was invited to join, along with family and friends, while Move Challenge participants received complimentary passes for the activities of their choice. For many of us, that included taking on the aerial challenge and ropes course! A little challenge, a lot of fun, and some great memories with the team. 💙

Before a valuation report reaches a client, opposing counsel, regulator, or other reviewer, there’s one important question worth asking:

Would an informed reader be able to understand how you got from the available information to your valuation conclusion?

In her latest article, TSS Advisors Partner Karen Lascelle, CPA, CVA, CFE shares a practical 30-minute framework for reviewing valuation reports before they move on to a more detailed technical review.

The “Grade Me” framework helps reviewers evaluate six key areas, including:
✓ The assignment
✓ The factual foundation
✓ Significant assumptions
✓ The analytical narrative
✓ Reconciliation and consistency
✓ Overall credibility and defensibility

💙 The final stop during our teamwide Community Day earlier this summer was COVER Home Repair & Store in White River Junction, VT!

Together, we sorted and stocked every donated item that was waiting to be processed, helping ensure the store was ready for shoppers. 🛍 We also reorganized the furniture showroom to create a display that was easier for customers to browse and purchase items.

Every item we placed helps make affordable home goods available to local families while supporting COVER's mission of providing home repair and housing assistance to local families in need! 🏡
