What This Comparison Says About CORNERSTONE vs ROCK VALLEY
CORNERSTONE (Freeport, IL) and ROCK VALLEY (Loves Park, IL) are both federally-insured credit unions reporting quarterly to the NCUA, but they differ meaningfully in scale and profile. CORNERSTONE holds $168.8M in assets across 12,235 members, while ROCK VALLEY holds $172.3M across 15,693 members. On the composite health score, ROCK VALLEY comes out ahead at 76/100 versus 75/100 for its counterpart — a gap driven by the weighted combination of capital, loan quality, earnings, growth, and liquidity metrics shown above. Charter numbers 60189 and 68687 indicate entirely separate NCUA supervisory records; they operate under peer groups $100M–$500M and $100M–$500M respectively.
Capital adequacy is the first check: CORNERSTONE's net worth ratio of 9.71% clears the NCUA's 7.0% "well capitalized" bar, while ROCK VALLEY posts 11.19%. Loan quality — measured as loans 60+ days past due over total loans — comes in at 1.76% for CORNERSTONE and 0.94% for ROCK VALLEY; lower is tighter. Earnings efficiency (ROA) shows 0.000% versus 0.000%, though credit unions as not-for-profit cooperatives often report ROA near zero by design, returning surplus to members through rates and dividends. Loan-to-share ratios of 66.93% and 88.62% indicate how each institution deploys member deposits — the 60–80% band is generally considered the balanced-liquidity window by industry analysts.
Both credit unions are covered by NCUSIF federal insurance up to $250,000 per depositor per ownership category, the same limit as FDIC coverage at banks — so the comparison here is about financial efficiency and member experience, not deposit safety. Before joining either institution, verify the field of membership: CORNERSTONE is currently defined as "Other" and ROCK VALLEY as "Other", and eligibility rules (employer, geography, association) determine who can actually open accounts. Current deposit rates, loan APRs, fees, and product availability change continuously and are not reflected in quarterly Call Report data — contact each credit union directly before opening accounts or borrowing. This comparison is informational only and is not financial advice, an endorsement, or a solicitation; credit union performance can shift materially quarter to quarter and should be re-evaluated with current reports before making any decision.
What to Consider When Choosing
Net Worth Ratio: The NCUA requires credit unions to maintain a net worth ratio of at least 7% to be considered "well capitalized." CORNERSTONE shows 9.71% vs ROCK VALLEY at 11.19%. Higher ratios indicate stronger financial buffers.
Delinquency Rate: Measures the percentage of loans that are 60+ days past due. Lower delinquency rates indicate tighter underwriting and lower credit risk. CORNERSTONE: 1.76% — ROCK VALLEY: 0.94%.
Return on Assets: ROA measures how efficiently a credit union generates income from its assets. Industry benchmark is typically 0.50–0.70%. Both values here may be close to zero since credit unions are not-for-profit and return value to members through lower rates and higher dividends.
Membership eligibility: Check each credit union's field of membership before applying. Many restrict membership by employer, geography, or community affiliation.
