The 2017 Motorola Solutions Credit Agreement includes a $500 million letter of credit sub-limit with $450 million of fronting commitments.

An annual facility fee is payable on the undrawn amount of the credit line. The interest rate and facility fee are subject to adjustment if the Company's credit rating changes. The Company must comply with certain customary covenants including a maximum leverage ratio, as defined in the 2017 Motorola Solutions Credit Agreement.

Interest on the Term Loan is variable, indexed to LIBOR, and paid monthly. The weighted average borrowing rate for amounts outstanding during the three months ended March 30, 2019 was 3.75%. No additional borrowings are permitted and amounts borrowed and repaid or prepaid may not be re-borrowed. In February of 2018, the Company issued $500 million of 4.60% Senior notes due 2028. The Company recognized net proceeds of $497 million after debt issuance costs and debt discounts. These proceeds were then used to make a $500 million contribution to the Company's U.S. pension plan. As of March 30, 2019, the Company had $800 million of 2.0% Senior Convertible Notes outstanding with Silver Lake Partners which mature in September 2020 and are fully convertible. The notes are convertible based on a conversion rate of 14.8968, as may be adjusted for dividends declared, per $1,000 principal amount (which is currently equal to a conversion price of $67.13 per share). The exercise price adjusts automatically for dividends. The value by which the Senior Convertible Notes exceeded their principal amount if converted as of March 30, 2019 was $876 million. In the event of a conversion, the Company intends to settle the principal amount of the Senior Convertible Notes in cash.
